I have been incredibly remiss on just about everything for the past couple of months due to a rather unpleasant personal situation, but I think things are on the upswing because I'm back to being really bothered by things I don't understand.
That particular trait -- not being able to sleep when there's something you can't figure out -- is in my mind the fundamental requirement for being a scientist. I was groggily reading my email Friday and found a request from one of my NASCAR contacts to explain something "simple": why tires make white smoke, even though the tire is black and the skid marks are black.
The question, which was posed by Mike Bagley of The Morning Drive on NASCAR Sirius 128, is a really good one, and it followed right on the heels of a question from Danica Patrick after her Daytona debut as to why they can't make tires that don't generate so doggone much smoke when you skid. Danica was taken out of (aka "crashed and couldn't get back on the track for") the Nationwide race when the smoke prevented her from making her way around an accident ahead of her.
The two questions are linked: They both have to do with how and what you see. And they both made me think I knew the answer, realize I didn't, and then figure it out myself. I posted a companion video blog on this topic on the Stockcar Science Blog. The two pieces are for slightly different audiences, but most people should have no problem understanding both.
Let's start with electromagnetic waves. Waves are characterized by their wavelength, which is their repeat distance. The electromagnetic spectrum includes everything from gamma rays, which are very small (10-12 m, or a millionth of a millionth of a meter) all the way through radio waves, which can be kilometers long.
Our eyes detect visible light, and we need special instrumentation to detect other types of electromagnetic waves, like infrared waves. Visible light is a very small part of the electromagnetic spectrum, having wavelengths from 400 nm to 700 nm. Red, on one side of the rainbow, has longer wavelengths and blue/violet have shorter wavelengths. White light is the superposition of all visible wavelengths at once, and black is the absence of any color light. Natural sunlight contains all of the wavelengths of visible light, in addition to a lot of infrared radiation that makes the Earth warm enough to be habitable.
Just to give you an idea of how small the wavelength of visible light is: If the wavelength of light were equal to the length of a NASCAR
Sprint Cup car, California Speedway would stretch from the Earth halfway
to Venus. (From Earth's orbit halfway to Venus's orbit, technically.)
I'm not sure how many angels can dance on the head of a pin, but I know that you could fit 5000 wavelengths of blue light across the diameter of a 2mm pin. (Light dances. It likes nu-wave music.)
The wavelength of light is important because it provides us with information. We see things in one of two ways: either the object emits light (e.g. the Sun, a light bulb), or the object reflects (or scatters) light from another source. When you look at me outdoors, sunlight strikes my hair, my hair absorbs some wavelengths and reflects others. The reflected wavelengths make it to your eyes where they register as 'reddish-brown'.
Most things we look at are much, much larger than the wavelength of the light we use to look at it. But optics gets a little trickier when you start looking at things that are comparable to (or smaller than) the wavelength of light. Imagine trying to pick up sesame seeds with a pair of kitchen tongs. The tongs are just so large that they don't "see" the sesame seeds.
The gas molecules that form the atmosphere are smaller than the wavelength of light. (In fact the size of a typical molecule is comparable to UV light. When light hits these molecules, it doesn't reflect back so that you can see the molecules. The molecules absorb the incoming light, which increases their energy. To get rid of the extra energy, the molecules emit their own light. When the scatterer (the molecule) is much smaller than the wavelength of light, shorter wavelengths scatter much more strongly than longer wavelengths. (The intensity is proportional to the inverse wavelength to the fourth power, so if you double the wavelength, you decrease the intensity of the scattered light by 64 times.) This wavelength-dependent scattering is called Rayleigh scattering and explains is why the daytime sky is blue. I've illustrated this schematically by showing white light coming in from the left and blue light being re-emitted from the atom or molecule that is doing the scattering.
What color is steam? Boil a pot of water and look close to the surface. You will see... nothing. Water vapor is colorless. So why do you see white steam above the surface of the water? (BTW, a beaker and hot plate works much better than a pot). There is a decreasing temperature gradient from the surface of the water up. The hottest water molecules are nearest the water surface. As the molecules rise and move further from the heat source, they collide with other water molecules and condense into water droplets that are close to the same size as the wavelengths of visible light. Instead of Rayleigh scattering, we get nonspecific or Mie scattering. When the scatterers are comparable to the wavelength of light, the scattered light doesn't change wavelength. Whatever color light comes in is the color light that is scattered. As with Rayleigh scattering, you're not actually seeing the object that's causing the scattering, you're just seeing the effects the scatter causes.
Back to tires. Tires are complex objects chemically and mechanically. Tires are made of rubber -- often three or four kinds, some natural and some synthetic -- plus some processing oils, fillers (usually carbon black and/or silica nanoparticles), vulcanizing molecules (sulfides, zinc oxides) and anti-oxidants or anti-ozonants. Rubber polymer chains are long, like spaghetti, and they don't bind to each other very well. The fillers and vulcanizing molecules tie the long rubber polymer chains together, forming a strong and resilient material that allows a stock car to corner at 195 mph without the tire coming apart. Different parts of the tire are made with different types of rubber: it seems sometimes to be more of a black art than a science.
Speaking of black, tires don't have to be black. You can buy white bike tires, but I haven't found any white car tires. Natural rubber (the sticky, gooey sap of the rubber tree) is sort of a milky off-white. Tires are black because the filler material used to modify their mechanical principles -- carbon black -- makes them black. (Wouldn't you think white tires would get really dirty really fast? Good thinking - let's just put the dirt in the tire at the very beginning and get it over with.)
Carbon black is like soot with very large surface area. The carbon particles are amorphous or graphitic-like in structure and from 10-50 nanometers in diameter. (A human hair is about 70,000 nm - 100,000 nm.) Carbon black nanoparticles aggregate into fractal shapes that disperse through the rubber. The large surface area helps form bonds between the rubber polymer chains and improve the mechanical properties of the tires, reinforcing the tires and helping to conduct heat away from the tread. Carbon black used to be known as lampblack - it could be produced by burning oil lamps. Today, carbon black is made from pyrolyzing (a fancy way of saying "burning") tar oil.
Tires -- especially race tires -- are designed to work at high temperatures. Those high temperatures are produced by friction between the tires and the track. Under normal conditions, it's not unusual for a tire to reach 250 or 275 degrees Fahrenheit. When a driver skids from 200 mph to a stop with the tires locked up, we're talking a lot more than the usual amount of friction and thus a lot more heat.
You can't really melt a tire. Rubber is long polymer molecule (think spaghetti) that is usually more like thick slime than tire. Vulcanization uses molecules like sulfur to make bridges that hold the polymer molecules together. Vulcanization process made rubber a viable material: Until it was discovered, rubber items were flimsy and tended to melt when the temperature got warm.
The fillers (carbon black and silica) also form additional bonds between the rubber chains and this is one reason that tires are such a disposal problem: you can't just melt them down and recover the original rubber. Once you've made a tire, you're stuck with it. That's why most tire recycling schemes involve shredding the rubber and using it as a filler in another material like pavement or that soft stuff they put at playgrounds now so that kids don't get hurt when they fall down.
Under normal circumstances, a tire wears. Small pieces of hot rubber get scraped off the tire by the track, mix with track grit and form 'marbles'. When subjected to high temperatures and sliding, lots of tread material comes off in small particles. Those small particles -- comparable to the size of the wavelength of light -- scatter whatever light is incident on it. If you shine white light on tire smoke, the smoke will look white. If you shine red light on the smoke, the smoke will look red.
Carbon has an exceptionally high melting point - 6400 degrees Fahrenheit, so much of the carbon black, and any rubber molecules that didn't let go of it, is deposited on the track. That's why the skid marks are black. Black tires, black skid marks, white smoke. It's just another example of how nature likes to surprise us when we make things small.
Drifters (the ones who go around corners transversely instead of longitudinally like the rest of us) get points for creating tire smoke, so Kumho actually manufactures a tire that creates colored smoke during burnouts. A dye embedded in the tire sublimates (goes from a solid to a vapor) when it is heated. You can buy red, blue and yellow -- the latter only available for 17 inch rims for some reason. Not that it matters for me: In NASCAR, the only time you want to see tire smoke is if you're doing a burnout after winning the race.

It was a whirlwind weekend at the AAAS meeting in San Diego, where the Spousal Unit and several interdisciplinary colleagues expounded on the mysteries of the arrow of time, and Jen-Luc Piquant hobnobbed with all the coolest avatars in virtual Webspace. As for me, I moderated a spiffy panel discussion in my role as director of the Science and Entertainment Exchange: "Watching the Watchmen and Cheering the Heroes: The Science of Superheroes." In keeping with the Exchange philosophy of promoting an equal partnership between science and Hollywood, we had two physicists, a biologist, a film screenwriter, and two TV writers -- because sure, Hollywood can learn a lot from science, but science has a lot to learn from Hollywood as well. (Like how to cuss and make it seem perfectly natural: I suspect our session set a record for the most "F" bombs dropped in a AAAS session, and the audience seemed to find it refreshing -- including me. Somehow, when scientists try the same thing, they just seem like they're trying too hard. Effective cursing is its own art form; do it with panache, or don't bother.)
First up: Sid Perkowitz, a physics professor at Emory University turned full-time science writer and author of Hollywood Science, among other tomes. A couple of the write-ups of the session make him out to be a typically overly-literal curmudgeonly scientist complaining about "bad science" in fictional entertainment, with the usual calls to lighten up. I'm all for scientists lightening up a bit when it come to Hollywood, but I'd never direct that criticism at Perkowitz, who I've known for years. He's okay with film and TV starting off with an unlikely premise: a man can fly! Something can move faster than light! In Hollywood, this is called a "buy" -- something you ask the audience to buy into at the outset in good faith, in return for an awesome story -- and most projects allow themselves one or two "buys". After that, he'd just like the writers, etc. to do their best to ensure that no scientific concepts are seriously harmed in the making of said film.
Perkowitz watched a good 120 science fiction films in his research for Hollywood Science. More than 1400 science fiction movies have been made since 1902, he says, almost all of which begin with a nugget of real science. And science plays a major role in a full 19 of the 50 top-grossing movies of all time. The results, according to Perkowitz, are often mixed in terms of how science (and scientists) is depicted. The good: Contact (duh) has one of the best depictions of an actual scientist, and a woman to boot, ably played by Jodie Foster. Perkowitz is also a fan of last year's indie film Sleep Dealer, District 9, and Moon, although he reserves highest praise for Gattaca, which not only has plausible science, but explores a genuinely relevant issue about how much of who we are is determined by genetics, and how much is determined by our environment and just sheer force of will (the choices we make and how hard we're willing to fight for what we want).
I'll join Perkowitz in singling out Apollo 13 for special praise: more than any film I've seen thus far, it captures a period in US science history perfectly and made audiences feel the full import of what it took to get astronauts to the moon. I mean, we went to the moon in a souped-up Buick, people! And when something went horribly wrong on the Apollo 13 mission, our men were literally stranded in space. It's not like they could call AAA to bail them out.
Those astronauts figured they probably wouldn't get back safely -- and yet they did, thanks to science! (Jen-Luc thinks Ed Harris is the manliest of men when he barks at his team not to panic: "Let's work the problem, people! Let's not make things worse by guessing.") My favorite scene is when Tom Hanks' character has been doing a calculation for their re-entry. Get it wrong, even a little, and they're all dead. He asks all the scientists back down on Earth to check his math, and there's this great shot of a row of nerds in white shirts, glasses, pocket protectors and the odd bad comb-over giving a series of thumbs up as their calculations match Hanks'. The message is clear: science saves lives.
Ah, but then there's teh bad: The Core takes top honors, with its ludicrous plot about drilling to the Earth's core, which has mysteriously stopped spinning, in order to detonate a nuclear device that will hopefully kick-start the core's rotation. And finally, we have teh ugly: Starship Troopers, because those giant insects not only would collapse under their own weight were real insects scaled up to that size, but they aren't the most attractive creatures from another planet (which is probably the point). But even the bad and the ugly can provide "teaching moments" and great way to engage the public in thinking about science as it relates to their lives -- and hopefully inspiring them to want to learn more.
One person who tends to agree with that is Alex Tse, one of the screenwriters for Watchmen, based on the Citizen Kane of graphic novels (created by Frank Miller Alan Moore). And he phrased it much more colorfully than Perkowitz. "I know shit about science and I'm probably the least qualified person to be on this panel," he insisted. ("Not so!" Jen-Luc protests. "He had great things to say about the inherent tension between story and science in entertainment." Indeed he did.) "But the work I'm really attracted to, and that I admire, and the work that I aspire to do, there's a plausibility in science that I think adds to a timeless quality... of a film. You have some films that are kind of ridiculous and are kind of fun and entertaining to watch but they don't have that lasting effect." (*cough* Michael Bay *cough*) It's a point I've made repeatedly whenever people ask why Hollywood even cares about scientific accuracy. They care about plausibility and willing suspension of disbelief, because if the audience gets jolted out of the moment at any point by a ludicrous plot twist, it ruins the overall experience for them. That's not entertainment.
And you know, they really do think science is cool, and have tons of respect for scientists, despite long-standing stereotypes of mad scientists, geeks and nerds. "One thing I've learned is that you're not a scientist until you wear glasses and have a pipe," joked Jim Kakalios, a physicist at the University of Minnesota and author of The Physics of Superheroes. He even brought along a prop pipe to drive the point home. Kakalios has been using comic book superheroes in his classes for years to illustrate fundamental concepts in physics. And Watchmen offers plenty of grist for that particular mill.
For instance, Dr. Manhattan (or "Big Blue," as Jen-Luc prefers to call him) is an excellent framework for discussing difficult concepts like electron diffraction, his ability to pass through walls is a great segue into quantum tunneling, and his telltale blue hue can be attributed to leakage from high-energy electrons via Cerenkov radiation, according to Kakalios. Also? That full-frontal CGI nudity favored by the good doctor sends another positive message: "Physicists are very secure in their sexuality." Sharp observers might notice that, apart from his initial re-materialization after his accident, Dr. Manhattan starts out wearing some semblance of clothing, and over time wears less and less. Over lunch after the panel, Tse mentioned that this was deliberate: it was a direct consequence of Dr. Manhattan's growing isolation from humanity. Basically, the less human he became, the less he cared about trivial concerns like clothing and nakedness or shame. So, it wasn't, like, gratuitous or anything. That nudity was thoroughly Justified By The Plot.
Kakalios was the technical consultant on Watchmen, a match made by the Exchange while the program was still in its pilot phase, and he made the most out of his experience, even producing a YouTube video, "The Science of Watchmen," explaining some of the physics concepts underlying the film. Not only did it garner him an Upper Midwest Regional Emmy award, but more than 1.5 million people have viewed it so far. "If I taught 500 students a semester, two semesters a year, for 15 centuries, I wouldn't reach that many people n demonstrating electron diffraction," he says.
It's tough to argue with the numbers. Perkowitz compared the box office for An Inconvenient Truth ($49 million worldwide, one of the top-grossing documentary films to date) to that for The Day After Tomorrow ($544 million worldwide). The scientific community cringed at the way the latter depicted climate change -- global warming never seemed so exciting, with enormous catastrophic changes happening in mere hours! -- but it certainly created a sense or urgency in audiences that the documentary failed to achieve. It got people "thinking and talking about global warming, and that was a good thing," Perkowitz insisted, even if the science wasn't up to par. People don't mind if certain narrative liberties are taken, but they are savvy enough to know when the science is totally bogus -- and they don't like it. "The Core did not make money because people understood the science was so out to lunch," said Perkowitz.
Sometimes the issues having nothing to do with science. Tse's biggest beef with Watchmen -- despite being one of the people who wrote the script -- is when Dan (a.k.a. Night Hawk) breaks into supergenius Adrian's corporate office and hacks into his computer with just a few meager attempts to guess his password. "Adrian is the f*&#-ing smartest guy in the world, and Dan goes in and types the password and he's in," Tse gripes. See, even the screenwriter can't win sometimes. You can't please everyone -- not even Hitler, who had his own gripe about the deletion of the giant squid from the film version (expressed in NSFW subtitles, because Hitler is quite the potty mouth).
Heroes writers Aron Coleite and Joe Pokaski know this better than anyone: they've been involved with the series since its inception, and have worked on each of the 76 episodes so far. Along with well-deserved praise, they've also endured their share of scorn and fan dissatisfaction with the creative direction the series took in later seasons. If that weren't enough, they have to deal with scientists nerd-gassing about all the scientific liberties taken in the plot. "We know a lot of this stuff is inaccurate," Coleite admitted, "but we try to make it seem plausible. We spend hours in a stinking room arguing about invisibility. We really do think long and hard about how to explain stuff like whether clothes are visible on an invisible person, or if anything the person touches also becomes invisible." See? Hollywood is not as glamorous as it seems. And even when they come up with a solution, it doesn't always get explicitly stated on-screen. "We're demonstrating it visually. We don't bother people with saying 'It's an invisible field around them that distorts light and that's why Claude is wearing clothes."
Kakalios said something similar about his Watchmen experience: even if the underlying science never made it on-screen, the filmmakers still wanted to know every last detail, because getting even the tiniest thing wrong would ruin the illusion they were trying to create. His favorite scene in Iron Man, for instance was when Tony Stark uses the correct soldering tool -- and in the right way! -- in his lab while building his superhero armored suit. "So you're not thinking about Robert Downey Jr. playing a role, you're thinking about Tony Stark making an Iron Man suit."
"We always try to stay true to scientific accuracy, while occasionally diverging for emotion or story-telling," said Pokaski. "We have enormous respect for scientists and if the science seems off, the audience is going to tune out." It's quite the balancing act on Heroes, with characters who can fly, read minds, heal spontaneously, control time, and be invisible, yet the writers try to remain somewhat consistent with their bending of the science. That said, "We absolutely bastardize science terms to the point where your toes would curl," Coleite declared. There are good reasons for this. For starters, the story will always win out over the science because this is entertainment, folks -- it's all about telling a good, convincing story. It's about compelling characters, and authentic emotions. And that means that often, certain liberties must be taken. The science need not pass peer review; it just needs to be good enough to be plausible and rope in the viewer.
The premise behind Heroes, for those who don't follow such things, is that a small subset of otherwise ordinary people spontaneously develop special abilities: flying, telepathy, quick healing, walking through walls, manipulating space-time, and so forth. The explanation offered is a sudden mutation in their genetic code; they are the next step in human evolution. Our last (but far from least) panelist, Nicole King, is an evolutionary biologist at UC-Berkeley, who had one burning question: what's the mechanism by which this happens? The show doesn't offer an explanation. "We try to have everything based in emotion," Pokaski said. Their
background isn't so much in science, as in science fiction, and more
often than not, leaving something to the imagination works better than
spelling everything out when it comes to science fiction. "The more you try to explain, the sillier it
sounds," he said.
That didn't stop King from investigating a few possibilities, most notably the means by which single-celled organisms developed "super traits" that led to them evolving into higher life forms: animals and people. I rarely write about this subject, so it was fascinating to hear about the concept of "hopeful monsters," which Wikipedia describes as "a colloquial term used in evolutionary biology to describe an event of instantaneous speciation... which contributes positively to the production of new major evolutionary groups."
The Heroes are hopeful monsters; doesn't that make Evil Sylar, from Season 1, a bit more likeable? King used the example of butterfly species. Some species are poisonous, so predators avoid them based on, say, their coloring or wing patterns. Another species spontaneously adopts said coloring and patterning -- even though it isn't poisonous -- as a means of evading said predators.
The term was coined by geneticist Richard Goldschmidt in The Material Basis of Evolution as a means of explaining how nature managed to bridge the gaping chasm between microevolution and macroevolution. He didn't think small gradual changes over time -- a more common understanding of genetic mutation -- was sufficient to account for evolutionary leaps forward. In fine scientific tradition, his colleagues ridiculed this idea, although by 1977, Stephen Jay Gould was arguing that Goldschmidt may have been onto something. By then, regulatory genes had been discovered, which seemed to support some of the earlier scientist's ideas. Not all of them, though. From the brief reading I've been doing, this is an issue still under debate, because other advances in our understanding of the human genome appear to undermine the Hopeful Monster model. (Apparently, while macromutations do occur in the wild, and in human diseases based in genetics, they tend to be "removed by natural selection.")
A Boing-Boing write up summed up another of King's key points best:
[King] brought up a really interesting point about the intersection between evolution and sci-fi. Evolution, as you know, is driven by random mutations in DNA, and most of those mutations have no visible impact at all. DNA changes, but nothing important happens to the overall organism.
Other changes in DNA lead to negative impacts—for instance, the mutations that lead to cancer. Finally, and luckily, some mutations are beneficial. But, King reminded me, they're very seldom only beneficial. The same innovative mutations that make an organism stronger are usually also associated with at least one biological trade-off. You may gain, but you also lose. And whether the mutation gets counted as "successful" depends a lot on how the benefits and detriments balance out. Think about what that could mean for, say, the X-men? Should Warren Worthington III be dealing with the osteoporosis that must surely go along with his light, flight-ready bone structure?
The question of how much of who we are is genetically determined, and how much is a factor of environment and the choices/decisions we make, underlies the entire story arc of Heroes, which explores the question of destiny versus free will when it comes to our identity, our abilities -- and our future. It's a theme in Watchmen as well: our flawed tragic heroes struggle with whether they can change the catastrophic future, or whether the nuclear blast that devastates humanity at the end is, frankly, inevitable.
That's the true power of science fiction: not only can it entertain and inspire the next generation of scientists, but it provides a compelling framework in which to explore how science fits into our culture at large, and the inevitable ethical/philosophical questions that accompany major breakthroughs in research.

It's Valentine's Day again, which means it's time for various media outlets to turn an analytical science-y eye on that most magical-seeming human emotion: love. The inevitable tension is best captured in the romantic comedy Sleepless in Seattle, where various characters talk about the "magic" of the moment when they first knew they'd met "the one." Except for the psychiatrist, who reassures his sister, the recently-engaged Annie (Meg Ryan), that a little trepidation before marriage is perfectly normal: "What we think of as love is merely two neuroses realizing they're a perfect match." It's a movie, so magic wins out in the end, despite the great distance (Seattle and Baltimore). But there's no denying science plays a role in human beings in love.
The film dates from 1993, and it shows: the Internet was just in its infancy, and online dating was seen as suspect, if not outright dangerous. How could you possibly find the perfect match in CyberSpace? (Regular readers already know I met the Spousal Unit through our respective blogs, which isn't exactly a dating service, but proves the same point: technology can help two people find each other, even if they live thousands of miles apart.) There are still plenty of caveats and disagreements about just how successful things like eHarmony and Match.com have been, but today, according to this article at Discovery News, online dating has largely lost its stigma: it's just seen as one in a broad arsenal of tools people use to find romantic attachment.
In one of the first studies to compare newlyweds who met online with ones who met through more traditional routes, researchers found that online daters were slightly older and their courtships had progressed more quickly. But meeting online didn't mean people were any less attractive, intelligent or self-assured. Once they were married, the way they met had no impact on their relationships. ... "Our preliminary results suggest that, in terms of personal qualities, people who meet online are not that different from people who look for partners through other mechanisms," said Alicia Cast, a sociologist at the University of Iowa, Ames. "I'm not sure technology is altering things as dramatically as people think it is."
Scientists still have a lot to learn about love (or any other human emotion, for that matter), but biochemistry certainly plays a role in how we form attachments, most notably dopamine -- released in response to pleasurable activities, and highly concentrated during the early infatuation phase of a relationship -- and oxycontin oxytocin and vasopressin. (The former is the same chemical scientists believe help mothers bond with their infants.)
Various parts of the brain are involved as well. Back in 2004, Forbes reported on the work of Andreas Bartels and Semir Zeki, who claimed to have produced the first fMRI images of your brain on love. There is still some skepticism about their work; Caltech neuroscientist John Allman, for instance, cautions in the article about the difficulties of distinguishing between love and lust on fMRI scans, although Bartels argues his scans are markedly different from the areas of the brain activated when subjects are, say, watching pornography.
In fact, he's compared his fMRI images of people in love to those of mothers looking at their infants, and found the scans were almost identical -- except in the former case, there was extra activity in the hypothalamus, which is linked to sexual arousal. The reward center of the brain lights up when we're in love (winning the lottery produces the same effect), but what's really interesting is which regions get turned off: those commonly associated with things like moral judgement. Apparently love really is blind, and Bartels has the fMRI images to prove it:
The study of love continues apace. According to this article in the Los Angeles Times, there's a new study by Bianca Acevedo (a postdoc at the University of California, Santa Barbara) that suggests one bit of conventional wisdom isn't true: the notion that after the first flush of romantic excitement wears off, partners settle into a less intense, more companionable relationship that is far less thrilling than the infatuation phase. Acevedo says this isn't the case for roughly 30% of US married couples. She looked at brain scans of couples married 20 years or so and still claimed to be in love -- and they showed the exact same neural activity as newlyweds, "only without the anxiety or obsession." I've only been married to the Spousal Unit for 2-1/2 years, so things are early yet, but one of (many) reasons I married him was the same lack of anxiety or obsession -- without sacrificing the excitement of being in love. It's a rare gift.
Apparently all that relationship advice meted out by therapists the world over has some basis in science. "Doing novel, exciting things together boosts marital happiness," according to Acevedo's study, perhaps because this releases dopamine. Ditto for focusing on positive rather than negative aspects of your partner or relationship, resolving "conflict smoothly and quickly," being affectionate, communicating readily, and, of course, sex -- all these things can trigger an influx of oxycontin oxytocin, apparently.
And speaking of sex, what Valentine's Day post would be complete without Mary Roach, author of Bonk, giving a TED talk about the 10 weirdest things you don't know about orgasms? Bonk ranks as one of the best popular science books ever written, in my opinion, because in addition to some truly fascinating science, Roach approaches her subject with good humor. (I especially like the bit about the woman who experienced orgasm every time she brushed her teeth: "You'd think think woman would have excellent oral hygiene," Roach wryly comments, but apparently not: the poor woman assumed she must be demon-possessed.) I dragged the Spousal Unit to Disneyland and to Vegas for the calculus book; Roach's long-suffering husband did the deed in an MRI machine. Now that's a testament to true love.

Okay, the Semester From HellTM is over and I'm back to my usual teaching schedule, which means you'll be hearing from me more often. Part of my Semester from HellTM involved teaching basic computer skills (mostly Microshaft's Office Suite) to remedial freshmen, along with a little computer history. While I don't have a degree in computer science, I'm eminently qualified to teach this class, because I've been a power user (and often the only troubleshooter) of PCs since 1986. It was great fun recalling my earliest adventures with floppies, command lines, and ASCII in the context of a history lecture, and I felt oddly subversive as an English major and amateur geek talking about Charles Babbage and Ada Lovelace and the Difference and Analytical Engines. But it was also somewhat fitting, I believe. After all, Babbage felt free to comment on Alfred, Lord Tennyson's poetry. Wikipedia (my students' favorite source of information) recounts the following story about Babbage:
Babbage once contacted the poet Alfred Tennyson in response to his poem "The Vision of Sin". Babbage wrote, "In your otherwise beautiful poem, one verse reads,
- Every moment dies a man,
- Every moment one is born.
- ... If this were true, the population of the world would be at a standstill. In truth, the rate of birth is slightly in excess of that of death. I would suggest [that the next version of your poem should read]:
Strictly speaking, the actual figure is so long I cannot get it into a line, but I believe the figure 1 1/16 will be sufficiently accurate for poetry."
I fear Randy Olson's retort to this would be, "Don't be such a scientist!" but I think it's lovely that Babbage felt sufficiently competent in poetics to comment on the work of a master like Tennyson. But then, this was an era when expertise was not so tightly focused as it is now. Scientists were well- and widely read in literature, and most were fine writers themselves; poets were not strangers to the practices of science. Writing (or rhetoric, more specifically) was one of the major constituents of the liberal arts education one received at a good university.
The hardest thing about teaching anybody anything is finding the right level of communication, and the right way to express the concepts. It would seem logical that you don't go all jargony on a rank beginner, anymore than you have to spend time explaining the basics to an expert. But you'd be surprised how hard it is to put that into practice. How much knowledge do you assume? And how clear an idea do you as an instructor or writer have of what each level of knowledge actually includes? One of the tricks of being a good teacher is to remember what it was like when you were just starting out. What didn't you know then that you know now? And then you determine the correct order in which to teach it.
But that's not all that you have to worry about, either. The next problem is expressing that knowledge clearly in a way that will allow the listener or reader to follow your argument and build on what they already know. When you're teaching, you tend to do this in a number of ways, using various media. You drag in handouts, you assign textbook readings, you draw pictures, you write concepts and key vocabulary on the board, you use PowerPoint, videos, diagrams, whatever you can get your hands on to reinforce what you're saying in your lecture. But in the end, it all boils down to words, and if you're not using them effectively and clearly, your students or readers are sunk.
I say "readers" because this is just as true in written communication as it is in oral, and I was reminded of that by a recent conversation on one of the professional editors mailing lists I belong to. As a some-time freelance editor, I occasionally proof and copy edit dissertations and so do many of my colleagues. This would have been unheard of for an English major when I was in graduate school, but apparently isn't uncommon anymore, especially in the sciences. One list member confessed, "I work in the Medical Communications/Education industry. We hire PhDs in our scientific services department. Many cannot write an acceptable abstract much less a full length scientific paper. In my day if you did not have the writing skills to write a dissertation you did not graduate." Damn straight, I thought, accompanied by the usual visualization of hand baskets on their way to hell.
The reply from another editor floored me:
The graduate program that [the previous poster] referred to confused writing in the sciences with writing in the humanities. In the sciences, generation of original research and knowledge is the goal, which is separate from writing about that goal. For this reason, it is acceptable to not have writing skills to write a dissertation. Working scientists use writers and editors to communicate the thoughts of their (the working scientists') thoughts. In contrast, in the humanities, the author of the thought is also the author of the words that express that thought. Poets do not use writers to express their (the poets') thoughts.
Many thanks to Tom Lang, internationally recognized biomedical communicator, for explaining the essential difference between writing in the sciences and writing in the humanities.
(Tom Lang, I should note, is in the business of medical writing, so it's to his advantage to make excuses for bad scientific writing.) But there was more from the original poster that I think really goes to the heart of the matter:
It is NOT acceptable to not have 'adequate' writing skills (not exemplary, just adequate). In addition to generating original research and possessing the required analytical skills the scientist must also be able to communicate both the essence and significance of that research - regardless of which industry you work in.
This ignited a very opinionated discussion with a number of other editors. Katharine O'Moore-Klopf, another medical editor, opined:
Hmmm. I'm not sure which era ("in your day and mine") that [the first poster] is referring to. But as a medical copy editor, I encounter plenty of manuscript[s] written by researchers--MDs, DOs, PhDs--whose strength is in research, not writing. It is accepted practice in research institutes and medical schools for such researchers to have their manuscripts heavily edited by professionals like me before the researchers submit those manuscripts for publication. This is a practice conducted in the open, not in the privacy and shame of dark back rooms, because we medical copy editors are not writing manuscripts *for* the authors but helping them *rework* what they have already written. Indeed, several medical journals routinely refer such authors to freelance medical editors like me so that the authors can pay us to help them get their writing up to speed. These researchers are professionals whose scientific research skills use a different part of the brain than is used in writing, a part that in some researchers is rather underdeveloped. Inability to write stellar prose is not necessarily a reflection on a researcher's intelligence.
In defense of the researchers' bad writing, Mark Farrell added:
. . . [C]ompetency in one field doesn't necessarily translate to competency in another, nor should we expect it to do so. I could care less if someone with a talent for science or medicine or whatever can't write their way out of a paper bag--or be able to write at all, for that matter. They could be functionally illiterate, but if they are able to accomplish things in their field that others can't, things that could benefit humanity, why on earth should they be hindered or discouraged from achieving those things because they don't know how to write?
And Laurie Rendon, a social sciences academic editor, agreed:
I don't think good scientists are, by definition, able to express themselves well in their native language. I've edited reappointment documents for professors, and I'm amazed at the variety of things profs are required to do: develop courses, teach, supervise grad students, serve on committees, apply for grants, design experiments, do research... and then present the results of the research. Writing is not everyone's strong suit. And almost no one can decipher a style guide or thick style manual; maybe one in 10 of my professor clients does a half-decent job with reference list or footnotes, and none get it right. Keep in mind that one professor will submit to various journals over the years. Cross-disciplinary journals and even journals in the same field use different style manuals, and many journals have their own style guide, so it isn't a matter of learning to follow a single manual. As for schools and professors encouraging grad students to find an editor, yes they do. I used to make a living working for grad students. Many were sent to e by their professors; others were told in their information sessions to hire an editor if they weren't good writers.
I have some quibbles with this comment because this is one of the things I teach: how to write research papers, and most of my students are in the social sciences. They know they have to get their references right, whether it's APA, AMA, or MLA and that's what they make those manuals for; nobody memorizes them, not even editors. You get to know them quite well through usage after a while, but master them? Hardly. Getting the reference style right is about following directions and examples; that's all. And surely if you have a Ph.D., you have the spare intellect to format your references correctly. Isn't that what junior authors are for? But I'll also admit that reference styles are absurdly detailed things and need extremely careful proofreading, if nothing else, by at least one fresh set of eyes.
The discussion, which had shifted from dissertations to professional communications (not communications with the general public; that's another issue) went on over several more digest emails, but by the time I twigged to it, it was over, and not worth reviving on that particular list. I do, however, have some very strong opinions on this topic, as my students could probably tell you. I suspect that editors and teachers of writing have some different (but not completely) views on the topic too.
First of all, I think we both agree that everyone needs an editor, regardless of how good a writer you are. No one except the most arrogant of writers (who often aren't very good) disputes this. Even the best writers need someone to rein them in, point out their inconsistencies, and to say, "hey, this isn't very clear; can you break it down better?" Writing is necessarily an extremely interior activity and what every writer is trying to do is to convey their own mode of thought, their point of view, to everyone else. When we write, we know what we're trying to say, but that doesn't mean our readers will follow our train of thought exactly. Sometimes we're less successful at conveying our meanings than at others. That's where your editor comes in.
An editor's job is not usually to completely rewrite your prose for you, even in what's called a developmental edit. Rewriting is another job altogether and involves working closely with the putative "author" to get inside their head. The problem with rewriting or ghostwriting is that sometimes ideas get lost in translation or twisted beyond the original meaning. I think this is especially true when writing about science. Look at how often reporters twist the original meaning of research (PDF). Even specialists can do this unintentionally if they aren't especially well-versed in the particular field, and if the author can't explain himself adequately, how do you correct this or better yet, prevent it? The tricky part of writing about science is not necessarily describing the experiments or the research, but interpreting the data. If the researcher can't do that in a clear way, how can his audience be expected to trust his conclusions? More importantly, how easy is it to distinguish fraud or sloppy science from sloppy writing? It's one thing if you're working in your second language, but if you can't put a coherent thought together in writing in your native tongue, that's a big-time FAIL in my book.
Secondly, as a teacher of writing, I believe you can teach just about anyone to be a competent, adequate writer. Not brilliant, because that takes some innate talent, but certainly competent enough to express oneself clearly and concisely. Like anything else worth learning, it takes some effort and practice, but the effort is often not even made because there seems to be a general contempt for the efficacy of good prose in the sciences. When I was teaching science writing at Michigan State 20 years ago, one of my students brought me his lab manual which, in the introduction, plainly stated that "scientists have no time for crafting elegant prose." It would seem to me that scientists have no time for inelegant prose. Who wants to waste precious hours laboring through poorly communicated research results when you can spend half the time with a well-written article and be more certain of what you've read? It doesn't even have to be elegant prose, but it does have to be clear prose. Everyone should know how to express themselves adequately and clearly in writing. Sadly, more people outside the than inside the sciences do, even though universities spend a lot of time and money on writing workshops, tutoring centers, and writing centers.
I'm sure you've run into plenty of impenetrable prose yourself, but if you'd like some concrete examples of how it can be fixed, George Gopen and Judith Swan have thoughtfully provided examples of both errors and fixes in their article "The Science of Scientific Writing: Writing and the Scientific Process," in American Scientist. In it, Gopen and Swan discuss how keeping in mind reader expectations and interpretative processes can help make your prose more accessible and clearer, and how making it clearer actually changes your own thoughts as an author about the subject. Their examples also show you how an editor's mind works and how their transformation of your convoluted prose may actually give a different meaning to your data than you intend. A knowledge of how people read, of how stories are structured, of the rules of grammar and punctuation, can not only improve your writing but your own thoughts. Their two concluding paragraphs are worth quoting:
The substance of science comprises more than the discovery and recording of data; it extends crucially to include the act of interpretation. It may seem obvious that a scientific document is incomplete without the interpretation of the writer; it may not be so obvious that the document cannot "exist" without the interpretation of each reader. In other words, writers cannot "merely" record data, even if they try. In any recording or articulation, no matter how haphazard or confused, each word resides in one or more distinct structural locations. The resulting structure, even more than the meanings of individual words, significantly influences the reader during the act of interpretation. The question then becomes whether the structure created by the writer (intentionally or not) helps or hinders the reader in the process of interpreting the scientific writing.
The writing principles we have suggested here make conscious for the writer some of the interpretive clues readers derive from structures. Armed with this awareness, the writer can achieve far greater control (although never complete control) of the reader's interpretive process. As a concomitant function, the principles simultaneously offer the writer a fresh re-entry to the thought process that produced the science. In real and important ways, the structure of the prose becomes the structure of the scientific argument. Improving either one will improve the other.
In other words, we do well to remember that communication of any kind is a two-way street: information is both presented and interpreted and the more clearly it's presented, the more likely the interpretation will be similar to what's presented.
This is something Isaac Newton grasped intuitively, as Thomas Levenson points out in his book Newton and the Counterfeiter. Early on, Levenson describes Newton's structure for his most famous work, the Principia. Levenson writes, "Nothing in Newton's science depends on the shape of this narrative. In any order, his proofs would be just as valid. But to take the reader on an odyssey that begins with the orbits of the planets and extends to bring the entire cosmos into view allows the larger implications of the Netwonian idea to emerge." Newton realized that he was telling a story, and that the structure and order of it mattered as much as the presence of his mathematical proofs that formed the core of his argument. He was consciously guiding the interpretation of his words, so readers would see the same significance and usefulness of the discoveries that he did.
Third, scientists bemoan with great regularity the scientific illiteracy (and innumeracy) of the general public, and frequently insist that they are the best communicators of that science.Gil Watson, in the UK journal The Humanist, writes (in a somewhat cumbersome sentence) that, "most scientists have been perfecting the communication of their particular area of science for the majority of their working lives to their colleagues." Er, not according to all those editors I quoted above.
And are you sensing a disconnect here?
How can scientists be the best communicators of their disciplines if they don't learn how to write well enough to communicate even with their own colleagues? If they need specialist editors to clarify their prose for people in their own general field, then it doesn't bode well for the non-experts. Sorry, people, but you don't get to have that both ways. And you don't get to complain about people knowing nothing about science when your lack of communication skills is a large part of the problem.
Finally, there's the cost. In case you haven't noticed, scientific journals are not cheap, even the electronic ones. This is because of something called the "first copy cost": the initial costs of refereeing, rewriting, typesetting, copy editing, and proofreading set up for that first journal issue of which all others are but pale copies. The cost goes down with each subscription, but the range is still pretty hefty: from $420 to $2,500 per article, and it can be as high as $4,000 per article. Per article. (PDF) While most authors who need help with rewrites shoulder the costs themselves (and line the grateful pockets of scientific copy editors), this still adds to the administrative costs of the journal with the to-ing and fro-ing. Hardly anyone gets a piece of writing right the first time, but a lack of intelligibility can waste a lot of time for staff and referees as well as risk having your research misunderstood and rejected.
Ultimately, as Gopen and Swan point out, writing is a form of thought, one that helps clarify what we know even to ourselves. Teaching does this too; you never have a clearer idea of what you know than when you have to teach it (read: explain it) to someone else, which is what a good scientific paper does. It's teaching your colleagues about a new result, a new idea, a new approach, a new hypothesis. The best and most creative scientists have not just not just mastered the art of explaining verbally but usually excel in it. This, in fact, may be an indicator for extraordinary creativity in the sciences. In their blog at Psychology Today, Robert and Michele Root-Bernstein quote physics Nobel Prize winner William D. Phillips on his own training:
In high school, I enjoyed and profited from well-taught science and math classes, but in retrospect, I can see that the classes that emphasized language and writing skills were just as important for the development of my scientific career as were science and math. I certainly feel that my high school involvement in debating competitions helped me later to give better scientific talks, that the classes in writing style helped me to write better papers, [emphasis mine] and the study of French greatly enhanced the tremendously fruitful collaboration I was to have with [a French] research group.
One wonders if those "better papers" weren't a factor in Phillips's success as much as his insights into methods of slowing down atoms. So really, it's not just about being able to communicate your thoughts to others; writing well should be part of every scientist's training to foster more creativity and clarity. It might put some of my fellow editors out of business, but overall, it could only be a boon to science.
And really, if I were a scientist, I'd be just a bit embarrassed to know that editors think so little of my abilities. I mean, some of these people are . . . poets! Imagine Tennyson commenting on Babbage's work: poets commenting on your scientific communications. C'mon, aren't you just a little embarrassed? Just a little?

If it's Thursday, it must be Berkeley. That's where I was a couple of nights ago, having driven up from Los Angeles to attend Lawrence Berkeley Laboratory's first-ever Science Cafe, featuring Jaime Paglia, co-creator and showrunner for SyFy's hit TV series, Eureka, with a special Skype appearance by Colin Ferguson, who plays Sheriff Jack Carter on the show. Berkeley isn't exactly a small town, with plenty of hip shops and hangouts and excellent restaurants, not to mention loads of students at a major research university, plus a world-class laboratory. But it manages to retain the flavor of one -- so much so, that author Michael Pollan (a resident) once teasingly described it as "a town of hall monitors" whose motto should be "Welcome to Berkeley. Now stop doing that." That's kind of the essence of a small town, where everyone knows everyone else's business -- and more often than not, has an opinion about it that they're just dying to share.
Eureka is an affectionate paean to the small town, with a twist: it's population is made up of brilliant scientists (and their families), all of whom work at a vast, sooper sekrit lab called Global Dynamics that gets a large part of its funding from the Department of Defense, yet is dedicated to curiosity-driven research -- at least in principle. The show is a dramedy that combines elements of Northern Exposure and The X-Files, according to Jaime -- and I'd throw in a dash of Scrubs and Gilmore Girls to boot. In fact, it reminds me a little of Buffy the Vampire Slayer and Angel without the mystical trappings, both of which combined drama with humor and featured terrific characters and smart, sassy dialogue. (Needless to say, I'm a Eureka fan.) "It's small town trappings with endless possibility," he says, and admits the show's premise is at least partially inspired by places like Los Alamos, Berkeley Lab, Livermore, Bell Labs, even Area 51.
There's definitely an over-arching mythology for Eureka, and among the tidbits Jaime divulged during the discussion is that we will finally get to explore the town's early origins in the upcoming season, which is slated to begin airing in July -- although he avoided specifics on exactly how the writers plan to explore that history. He also mentioned plans for a cross-over episode with another SyFy series, Warehouse 13, and I don't know if he was serious or not, but he toyed with the notion of a possible spinoff series focusing on the town's kids at the Tesla School.
I personally would love to see something like Eureka 90210, My So-Called Lab, or Saved by the Quark, because Jaime is right: the kids are some of the best characters, and we only occasionally get a glimpse of their lives. The high school science fairs in a town filled with scientific geniuses alone would make the show. And instead of jocks lording it over the geeks and nerds, being smart is cool, with academic achievement valued far more than athletics. In one episode, Carter's daughter, Zoe, is awaiting her IQ test results, and Carter reveals his own IQ is 111: "more than 100%!" It becomes the trendy high school insult for awhile (as in "That is sooo 111..."), although Zoe turns out to have a much higher IQ, and actually fits in quite well as time goes on.
For his part, Colin stumped the assembled science geeks by asking about Janelia Farm -- probably the closest thing to a real-world counterpart to the fictional town of Eureka. It's an interdisciplinary research campus founded by the Howard Hughes Medical Institute, and it opened its doors in October 2006. Located near the town of Ashburn, Virginia, it's an attempt to capture something of the curiosity-driven basic research that typified Bell Labs during its heyday, when researchers could pursue intriguing scientific byways without worrying overmuch about potential payoffs.
The primary focus is neurobiology, and related science, so Janelia Farm isn't quite as free-spirited and open-ended as it claims. But it's still a departure from HHMI's usual modus operandi: supporting researchers at their home institutions. At Janelia Farms, the scientists come from all over the country on six-year contracts and get all their funding internally, bypassing the traditional grant process. They all live nearby and work together in the same building, too, which -- in theory -- makes it easier to collaborate across specialties.
Janelia Farm sounds like a fascinating experiment, despite the usual chorus of naysayers, but I can't imagine they'll ever grapple with the kinds of complications that routinely plague Eureka: AI attack drones gone rogue, everyone in town sharing each other's dreams, nanobots pervading the lab and taking on the form of the local stray dog, rips in the fabric of spacetime, and Fargo literally turning green. Jaime swears he'll never do killer plants, but he really wanted to have one episode where Carter became pregnant: "I just wanted to write that scene where he looks down and notices he's lactating." The SyFy honchos understandably nixed the idea. (Jaime is a father twice over, and his daughter not only memorizes the dialogue on Eureka, she's begun creating her own 8-year-old versions of spec scripts.)
Jaime is well-versed in the culture of science, since his father was a researcher with the UCLA Medical Center for decades, and even spent some time at NASA training to be a medical officer for future manned missions to Mars -- the program was scrapped, so Paglia Senior never got to go to space. Yet. Space tourism might still be on the horizon. The Eureka writers also get assistance from their technical consultant, JPL's Kevin Grazier (who also consulted on Battlestar Galactica); the writer's blog, Eureka Unscripted, currently has a two-part interview with Kevin posted that's quite a fun read. (Kevin's a fun guy.)
It's always an interesting dynamic weaving real science into science fiction, and the Eureka writers manage that balance very well -- Jaime tries very hard not to resort to the equivalent of "magic," even though the science as depicted on the show is very much fictional (and far more advanced than our own). But the story is always going to come first. Frankly, what Eureka does best is capture the culture of science: the almost childlike enthusiasm and sense of wonder about the world, and the endless curiosity that drives scientists to ask questions, test theories, all of which leads to even more questions. They worry about their funding, deal with family crises and lab mix-ups, and above all pursue interesting science. The scientists are also believably diverse (male, female, black, Asian, short, tall, chubby, plain, good-looking, and everything in between). Fargo might be the quintessential nerd, but Nathan Stark is tall, dark, handsome and brooding, and very much a slick "company man." Carter's love interest, Allyson, ends up heading Global Dynamics in Season 2, while Henry is the wacky experimentalist with the high ideas who serves as the town's conscience -- perchance even its "soul," if a town can be said to have one.
One of my favorite episodes is in Season 1, where Henry's old girlfriend visits with her husband, a brilliant (supposedly) scientist with a reputation for sweeping in and solving any challenge at the 11th hour. Except it turns out he's not that brilliant -- he just has better technology, namely, a mind-wiping device that can "steal" people's memories for a certain period of time... just long enough for them to forget the solution to a problem, so he can sweep in and pretend he solved it. He's done this to his own wife, of all people, stealing her own professional reputation and earning the accolades that should have come her way. The device he uses may be fictional, but the gender dynamic most certainly is not, and academic misconduct, while rare, does indeed happen.
The show does all of this without ever resorting to hidden agendas and overt "messaging," which make for lousy narratives. This being Berkeley, one questioner inevitably asked (a) why the show never deals with climate change, and (b) why there was no public transport system in Eureka. The answer to (b), per Colin, is that this would need to be done with CGI, which would be prohibitively expensive. As for (a), there has been at least one episode dealing with rogue weather patterns (and artificial weather), and c'mon -- Zoe tools around in a solar-powered car! Jaime also pointed out that if one looks closely in the pilot, Henry's gas station pumps biofuels. As for why Carter gets the job of sheriff when his female deputy, Jo, is passed over -- well, without Carter there wouldn't be a show, would there? And Jo's understandable resentment makes for great dramatic fodder, plus it reflects the kinds of issues that crop up in the real world. Or maybe, as Colin joked, Jaime is just a "sexist world hater." (The large number of strong, capable female characters on the show would belie that label.)
One of Jaime's favorite examples of this natural tension between getting the science right and telling a good story occurred when writing the episode "Blink," Eureka's version of a "Just Say No" anti-drug campaign (and a very effective one). Global Dynamic scientists under pressure to complete their projects by a deadline -- or risk losing their funding -- turn to a hopped-up form of speed. Jaime wanted to show one such user, having overdosed, moving so fast while running that he literally can run across the surface of Lake Archimedes without sinking. He asked Kevin how fast that would be. Kevin did some calculations and decided it would be around 565 MPH -- a speed at which the flesh would likely be flayed from the body, among other inflicted damage, so it was impossible. "Well.... I'm gonna do it," was Jaime's response, so Kevin sighed and gave him the basic outlines for a remotely plausible scenario.
With that one caveat (which applies to all science fiction, and fictional science), I think the science depicted on Eureka is pretty darn good. For instance, in one episode, the plot hinges on a prototype teleportation device that Global Dynamics abandoned due to complicated high-risk factors -- namely, that in order to teleport an object, one must destroy the original and rebuild it from scratch out of entirely new atoms in the new location. That's an aspect of quantum teleportation that rarely gets any prime-time play: people think it's as straightforward as what they see on Star Trek, but the quantum world is never simple, and the jargon in the series is generally pretty spot on, thanks not just to Kevin Grazier, but also Colin and co-star Joe Morton, who plays Henry. Both men are science buffs, and have been known to take issue with draft scripts where they felt the science was a bit too implausible.
Who wouldn't want to live in a smart house like S.A.R.A.H.? The acronym stands for Self Actuated Residential Automated Habitat, a literal "smart house" built inside an abandoned fallout shelter that serves as the residence of Sheriff Jack Carter. S.A.R.A.H. is an AI that can open and close the hermetically sealed doors, control internal lights and temperature, and make sure Jack has a nice cold beer on tap and a tape of the latest baseball game when he gets home from a hard day's work. In a pinch, she can diagnose injuries and compare current DNA samples against samples on file.
Jaime recalled that when he was first developing the series, he looked into the capabilities of a future "smart home" -- and discovered they already exist, sans the highly advanced AI. For instance, Georgia Tech has the Aware Home, an ordinary-looking two-story house tricked out with all the latest sensing equipment: cameras in the ceiling, microphones in the walls, and invisible trip wires in the doorways. And now there's even a "smart dollhouse", part of project called InterHome. Per a recent article in New Scientist:
Developed at the University of Hertfordshire, UK, the house is fitted with a network of infrared sensors connected to a central computer. By working out which rooms we tend to occupy at different times, software algorithms learn when we need the lights, heating or air conditioning systems turned on and, perhaps more importantly, when we don't, says Johann Siau, the project's coordinator. ...
InterHome also aims to boost home security. By connecting door and window lock sensors to the computer, it can send a text message to the homeowner if they have forgotten to lock the front door, for instance. Texting back will lock any doors or windows in question.
Before smart homes become ubiquitous, however, we might want to make sure the AIs behind them don't have S.A.R.A.H.'s rather mercurial temperament. She once locked Carter out when he forgot to call to tell her he'd be late, and when Carter considered leaving the town of Eureka, her abandonment issues kicked into high gear and she locked everyone inside -- using her laser defense system to zap the pizza delivery boy when he tried to escape. Keep your Smart Home happy, people... or else.

Millions of Americans were glued to their TV sets Wednesday night watching the State of the Union address, but let's face it, President Obama was overshadowed by the other big news of the day: the decidedly mixed reaction to Apple's announcement of the long-awaited tablet, with the unfortunate moniker of iPad. (As one of my Facebook buddies put it, "What's next, the Max-iPad?" And Mad TV's eerily prescient spoof is already making the rounds in the blogosphere.) I mean, even before the announcement, armchair pundits were looking into their crystal balls and declaring the product was doomed to failure. Bashing Apple is kind of a hobby for some folks, especially those with PCs who are understandably tired of certain Mac fanatics constantly trumpeting how much cooler they are. It's a vicious geek hierarchy: Macs look down on PCs, Linux users look down on Macs, and the really hard core types build their own computers from scratch and write their own damned operating system, thanks very much.
Once the iPad was unveiled, there were the usual sighs of "Ooh, pretty!" -- because, after all, Apple makes very attractive gadgets -- and a growing chorus of, "But... what about X feature?" Everyone has their pet peeve with the device. No built-in Webcam? You can't Skype? You can't multitask? Where's the USB port? (It doesn't have one.) Why doesn't it have a real keyboard? (You can buy an external keyboard as an accessory.) What good is a Web browser without Flash capability? (Personally I agree with Wired's Gadget Lab: it's time for Flash to die.) Really, all Hitler wants to do is watch LOLcats while reclining on his sofa -- and now he can't! Unless, you know, he uses his actual computer.
Gizmodo has a pretty balanced assessment of the device's pros and cons, based on a hands-on turn with the iPad. Chief among the Grumpy Guses is one of the bloggers at Lifehacker, who magically transforms a simple electronic device into a manifesto about the tyranny of DRM, urging consumers to fight "The Man" and boycott the iPad for the sake of creativity, freedom and individuality. (Can you say "lack of perspective"? Chill, dude. It's a souped-up e-reader.) Over at io9, Annalee is technically correct in her assessment that the iPad is "crap futurism" according to her narrow definition; it's an incremental improvement targeting a specific niche in the market, not a major paradigm shift. But for most of us, it doesn't have to revolutionize the future. Okay, maybe it is just a bigger version of the iPhone -- or more accurately, of the iTouch, since you can't make phone calls on your iPad. I never understood the point of the iTouch -- it always needed to be bigger to hold any kind of appeal for a user like me. And now it is bigger. Go, Apple!
Part of the confusion no doubt stems with Apple's unfocused marketing strategy: Is it a netbook? An e-reader? A replacement for your laptop? Annalee's "mythical convergence device"? Per Annalee: "Apple is marketing the iPad as a computer, when really it's nothing more than a media consumption device -- a convergence television, if you will." She closes with this admonishment: "Do not be content with a television when you can have a computer."
Um, okay, but I already have a computer, and I'm very happy with it. I actually just want a media consumption device, specifically for when I'm on long flights, and a "tarted-up e-book reader" might be just the ticket. I hate having to lug several heavy books when I
travel, and I hate having to settle for the limited "entertainment"
offered by most airlines -- they pick the content, which is often
edited from the original, and it might not be content I'm especially
interested in seeing. So if the iPad is going to give me in-flight
access to books, video, and the odd bit of Web browsing and simple
email capabilities, all of my own choosing, my interest is automatically piqued. You want to dismiss me and others like me as mindless zombie followers of Steve Jobs, or mere "sheeple"? Go right ahead. But as the xkcd cartoon below demonstrates, the "cult of individualism" can be a bit delusional as well. (The mouse-over text is classic: “Hey, what are the odds — five Ayn Rand fans on a train! Must be going to a convention.”)
My job is to be a content provider, and it's damned hard work, sapping my creative juices. So when I relax, I like to indulge in good old-fashioned mindless consumption; it recharges my mental batteries. Frankly, I'm not remotely interested in reconfiguring anything, even on my MacBook Pro. I want the damn thing to work without bugs, and if that means using sanctioned Apple programs, okay then. I have better things to do with my time -- which is why, for all my love of science, I'm just not a hardcore GeekGrrl. If it meets my needs, I'm happy, and so far, the Apple products I own all meet that basic criteria.
Furthermore, for all the weeping and gnashing of teeth (and rending of the garments in extreme cases) about the "limitations" of the "App store," there are thousands of approved apps on there, far more than I could ever hope to even browse, never mind download. There's plenty of choices available to me within those confines; I'm already overwhelmed by the options.
"The only way iPads can truly become futuristic devices is if we hack them so that we can pour whatever operating system we want inside," Annalee concludes in her own over-heated call to arms. "We need to jailbreak these media boxes so we can install the apps we want, not the ones provided by the Apple shopping mall." To which I say: Great! Hack away! Vive la revolution! I'd never deny the hackers their fun. They cracked the iPhone and I have no doubt they'll crack the iPad and congratulate themselves afterward on their own iconoclastic ingenuity and superiority. And then they can design and add their own apps with wild abandon. (If Apple just gave that to them, they wouldn't have the fun of hacking in the first place.) But let the rest of us consume our media in peace.
Now that we've got that out of the way, here are the things I am concerned about with the iPad:
Capacity. Only 64 GB capacity, tops? WTF, Apple? Your standard classic iPod contains 160 GB of data! Maybe you can fit a good number of e-books onto the iPad, but once you start adding in video -- especially for folks who want to watch HD format movies -- that's a serious limitation. Is it really that hard to add more memory for those of us who really want to load up for a long trip? I predict this will be one of the first things Apple upgrades in subsequent models. Because, honestly, that's a laughably small capacity.
The Battery. Apple is claiming 10 hours of battery life, which isn't bad compared to a laptop but pales in comparison to the long battery life of the Kindle. But that's in ideal lab conditions. I think it's safe to assume we're more likely to get 8 hours of battery life between charges, realistically. Which is probably fine for my stated use: to read books and watch video on long trips (especially since more airplanes are incorporating recharging outlets into their seats these days). Also, what happens when the battery finally dies? It used to be a simple matter to switch out the battery on my old MacBook Pro; the new version requires me to bring it into the Genius Bar. Before I buy an iPad, I'll want to know how they plan to handle battery replacement issues.
The LED Screen. There are pros and cons to this choice. The pro is that you get full color and can read Websites, newspapers, and watch video as they were meant to be viewed. The cons are that LEDs are an energy hog, limiting battery life, and honestly, it's hard on the eyes, especially for those of us who already stare at a computer screen much of the day. The Kindle is black and white, and uses electronic ink. The biggest advantage to using electronic ink for the Kindle is that it saves energy and thus extends battery life, giving our beleaguered eyes a bit of break. Then again, you can't watch full-color video on the Kindle. Nor can you read full-color magazines with pretty pictures. And forget about full-color graphic novels. Everything has to be specially formatted for the Kindle and let's face it, that format can be pretty limiting.
Now, publishers can get surprisingly creative to make the Kindle's limitations work for them. Take Archaia, which released the first graphic novel last summer specifically designed for the Kindle: Tumor, by writer Joshua Fialkov and artist Noel Tuazon. The gamble paid off: for the first few weeks after its debut, Tumor was the #1 download on Kindle, and enjoyed Top 20 status among all purchased graphic novels on Amazon. Not bad for a small independent title, going head-to-head with the likes of Spiderman and The X-Men.
It was a natural fit for hardcore comic book fans who know their history. As Fialkov pointed out on a guest blog post at The X-Change Files, graphic novels have never been just about color: "There is an entire world of gorgeous black-and-white comics, with rich traditions in the old newspaper strips of Windsor McCay, through the sub-culture work of R. Crumb, and on to the violent dark world of Frank Miller's Sin City."
Tumor embraces Chandler-esque "LA noir" with a vengeance to tell the story of Frank Armstrong, a down-in-the-dumps, out-of-work private investigator who finally gets a big job on the day that he's diagnosed with a terminal brain tumor. He resolves to solve the case and save the dame, while fighting off all the symptoms of a brain tumor (seizures, hallucinations, not to mention really bad headaches). The whole tale unfolds in black-and-white, which enhances rather than detracts from the experience. That, according to Fialkov, was a deliberate artistic choice for the Kindle:
With my book, we made a conscious decision in the creative process to help address the limitations of the device, and turn them into positives. At its heart, Tumor is a pulp detective story. To have it readable on the pulpy screen of the Kindle evokes, perhaps subconsciously, the look and feel of Black Mask or Weird Tales – books that were printed on newsprint during war time.
What we probably won't be seeing any time soon is a Kindle version of my friend Rick Loverd's Norse myth inspired, uber-violent graphic novel series, Berserker. I mean, I've seen the pre-colored pencils of various issues while they were in production, and they have a certain skeletal spare beauty in their black-and-white incarnation, but I can't imagine being able to fully appreciate Rick's loving depiction of exposed viscera (brought to vivid life by artist Jeremy Haun) in your standard Kindle format. But it would look fantastic on the iPad.
Title Selection and "Ownership" Issues. Okay, back to bitching. This is probably the single biggest concern I have, not just with the iPad but with the Kindle or any other e-reader -- it's not exclusively an Apple problem. In fact, it's why I've resisted buying an e-book reader so far: I like to actually own books, and I gravitate towards quirkier hard-to-find titles, or the kinds of books (science nonfiction!) that have only recently started appearing in e-book format. But the selection has gotten to the point where, for the kinds of books I read while traveling, most probably have Kindle versions available to me.
Then there's the ownership issue: Lifehacker has a valid point about DRM, even if he grossly exaggerates the issue. And once again, it's not exclusive to Apple. Amazon can yank a title whenever it wants, and suddenly I won't have access to a product I paid for. At least when I order a physical book from Amazon, it arrives on my doorstep and it is mine, to do with as I please. There have been unsettling instances where Amazon has arbitrarily yanked titles, like last year when copies of George Orwel's 1984 and Animal Farm mysteriously disappeared from the Kindles of people who had legally purchased them. Also last year, Amazon removed a bunch of gay and lesbian themed books from their sales rankings. As co-blogger Lee observed on her personal blog when the latter "glitch" occurred last year:
Among the books being stripped of their sales ranks and obscured in the search function are notable classics like James Baldwin's Giovanni's Room, Rita Mae Brown's Rubyfruit Jungle, E.M. Forester's Maurice, Edmund White's A Boy's Own Story, and Radclyffe Hall's The Well of Loneliness, all of which I've read in English classes at some point. Oddly enough, both Lady Chatterley's Lover and Lolita have retained their sales ranks (Lolita is up around 2,000). Also stripped of their rankings are Annie Proulx's Brokeback Mountain and Jeanette Winterson's Oranges Are Not the Only Fruit. Even Biological Exuberance: Animal Homosexuality and Natural Diversity has had its ranking stripped.
The message is clear: underage girls and marital infidelity are okay, but anything to do with homosexual relations (other than Christian screeds against it, which are fine) and those perverted animals who indulge in same-sex behavior have got to go. As Bruce Schneier, chief security technology officer for British Telecom and an expert on computer security and commerce, told the New York Times: “As a Kindle owner, I’m frustrated. I can’t lend people books and I can’t sell books that I’ve already read, and now it turns out that I can’t even count on still having my books tomorrow.”
Amazon still occasionally backslides into its naughty Big Brother ways. Sci-fi author John Scalzi just discovered yesterday that all his books under the Tor imprint mysteriously became unavailable on Amazon because of some dispute they're having with parent publisher MacMillan. While the corporations are playing Negotiator Chicken, Scalzi and other authors under MacMillan are, frankly, losing potential royalties because we, their readers, can't find the books on Amazon. (Fortunately there are always other options. Scalzi helpfully directs his Whatever readers to other book-buying sites that haven't blocked his titles... yet. And hey, why not use this as an opportunity to visit an actual brick-and-mortar bookstore before the species becomes extinct?)
So now we're back to Lifehacker's burning question of whether we want to support this kind of top-down "control" or fight back against The Man Tryin' to Keep Us Down. Frankly, there has always been some measure of control in the publishing industry. Publishers decide which books to publish. Bookstores decide which books they wish to stock, and can "censor" certain titles at any time (cf. Walmart). Amazon can arbitrarily decide to flex its marketplace muscles and not stock a specific title or, in the case of MacMillan, withhold an entire line of titles from a single publisher. It's disturbing, I grant you, but Apple is not the only offender when it comes to embracing this business model, nor is it the worst. In principle, Apple can adopt similar practices, or possibly implement even more draconian controls -- but it's not in its best interests to do too much of that. All they'll accomplish is discouraging on-the-fence potential buyers like me from entering the e-reader market.
There are always tradeoffs. No one device will please everybody 100%, no matter how hard it tries. The only question is whether the benefits to any given user outweigh the inevitable tradeoffs that must be made. For my part, I'm reserving final judgment until I check out the actual iPad in the store. It'll come down to that, the larger version of the Kindle -- or continuing to abstain from the e-book market altogether.

Fifty years ago, a handy little device was invented that would go on to change the world. I'm talking about the laser: without it, there would be no DVDs or BluRays, no laser light shows, no handy laser pointers to highlight the relevant portion of one's PowerPoint slide, no fiber optic communications systems, no corrective eye surgery, no supermarket scanners, tattoo removal, and so on. The laser is ubiquitous to modern technology, which is why the physics community is celebrating Laser Fest all this year, kicking off this past weekend in Berkeley with a special exhibit at the Lawrence Hall of Science.
“Laser,” for those who aren't inclined to Google it, is an acronym for Light Amplification by Stimulated Emission of Radiation -- quite the mouthful, so you can see why everyone just decided to call it a laser. It describes any device that creates and amplifies a narrow, tightly focused beam of light whose photons are all traveling in the same direction, rather than emitting every which way at once, like the light emitted from, say, a household flashlight.
How often do you stop and ask yourself, "Where does light even come from?" The answer is that it comes from atoms as their energy levels rise and fall back down to ground state. Anything that produces light – the heating element in toasters, gas lanterns, incandescent bulbs – does so by raising the temperature of the atoms that make up said object. This causes the electrons orbiting the atomic nuclei to jump to higher energy levels; when they relax back into their ground state, the excess energy is released as photons. The wavelength of the emitted light depends on how many levels the electron had to drop. Laser light is unique because it is "tuned" -- that is, it contains only one specific color, or wavelength.
There are many different types of
laser, but at heart, they exploit the same fundamental physics. You start with an empty cavity with two mirrors -- one of which is half-silvered so it reflects some light and lets some light through -- on each end. Inside that cavity is a crystal like ruby or garnet, or a gas or liquid. This is the "lasing medium." Now it's time to pump things up by applying intense flashes of light or electricity. You're literally pumping in extra energy, which is absorbed by the atoms or molecules of the lasing
medium. This boosts them above their ground state to a higher energy level. Atoms thus boosted are said to be "excited," and who wouldn't be when subjected to a sudden electric shock?
Then a photon enters the laser cavity, just minding its own business, but the space is pretty crowded, so chances are, it will bump into an excited atom. If that happens, the atom drops back down to its ground state and emits a second photon of the same frequency, in the same direction as the bombarding photon.
This produces a kind of domino effect: each of these may in turn strike other energized atoms, prompting the release of still more photons in the same frequency, all traveling in the same direction. The end result is a sudden burst of coherent” light as all the atoms discharge in a rapid chain reaction. This process is called “stimulated emission.”
Okay, stop giggling. That's what it's called! Check Wikipedia if you don't believe me. Anyway, Albert Einstein first broached the possibility of stimulated emission (oh, stop it!) in a 1917 paper. (Einstein did a lot of things in addition to special and general relativity.) He was a bit too far ahead of his time; or rather, it was an interesting effect, but nobody could figure out what it might be good for.
It wasn’t until the 1940s and 1950s that physicists found a novel use for the concept. It all started with radar, invented in 1935 by Sir Robert Watson-Watt. Yes, radar. Laser pioneer Charles Townes worked on radar systems during World War II. After the war ended, Townes switched his focus to molecular spectroscopy, a technique that studies the absorption of light by molecules (different types of molecules absorb different wavelengths of light). Just like radar, molecular spectroscopy bombards the surface of molecules with light and analyzes the ones that bounce back to determine the molecule’s structure. By 1953 he had patented a device he called a maser, for “microwave amplification by stimulated emission of radiation.”
Initially the technique was limited by the
microwave wavelength. Townes noticed that as the wavelength of the
microwaves shortened, the light interacted more strongly with the molecules,
which meant one could learn more about them. He thought it might be possible to
gain even more information by developing a device that produced light at much
shorter wavelengths, essentially extending the maser concept to the optical
range of the electromagnetic spectrum. The best way to do this, he thought,
would be to use molecules to generate the desired frequencies through
stimulated emission.
Townes mentioned the idea to a colleague (later his brother-in-law), Arthur Schawlow, who came up with the idea of outfitting the lasing cavity with mirrors on either end in such a way that only photons in the selected wavelength and frequency range would be amplified.
The two men wrote a paper detailing their concept for what they called a laser, and published it in the December 1958 issue of the scientific journal the Physical Review, although they had yet to build a working prototype. They received a patent for their design two years later – the same year that the first working laser was built by Theodore Maiman at Hughes Aircraft Company.
You can learn about all the gritty details at the LaserFest Website, which includes video interviews with Townes, Maiman, and a special documentary on laser applications. And for anyone who's in the Berkeley area tomorrow afternoon, Townes and a couple of other physicists will be giving a public talk at the Lawrence Hall of Science at 4:30 PM.
Interesting historical side note: as is often the case with revolutionary inventions, there was some question of the patent rights for the laser. Gordon Gould, a scientist at Columbia University and later with Technical Research Group (TRG), sued to earn patent rights based on his research notebook, which contained an entry dated and notarized in November 1957, describing his own design for a laser. Here's what the Washington Post had to say about it, in Gould's 2005 obituary:
While studying physics at Columbia University, Mr. Gould said, he conceived the idea for the laser Nov. 9, 1957, in the middle of the night. After jumping from bed, he chain-smoked his way through the weekend and that Wednesday raced his notebook from his Bronx, N.Y., apartment to a candy store to have it stamped by a notary public.
Confused by a lawyer's advice, he thought he first needed a working model and neglected to apply for a patent. This was a costly oversight, allowing other scientists to win credit for the laser, which Mr. Gould believed could cut, weld, measure distances and create heat that would trigger nuclear fission.
Gould fought for decades, and in 1973 the U.S. Court of Customs and Patent Appeals ruled that the original patent awarded to Schawlow and Townes was too general, and did not supply enough information to create certain key components of a working laser. Gould was entitled to patent rights -- which by then probably added up to a tidy sum of money.
There are several different types of lasers. Solid-state lasers use crystals whose atoms are arranged in a solid matrix, such as ruby. CO2 lasers emit energy in the far-infrared and microwave regions of the spectrum. This type produces intense heat, and is capable of melting through objects. Dr. Evil coveted such a laser when he demanded “sharks with frickin’ laser beams” on their heads to torture Austin Powers to death – only to be foiled because sharks are an endangered species. Imagine his disappointment if, in addition to having to make do with cranky mutated sea bass, they were equipped not with CO2 lasers, but with conventional diode (semiconductor) lasers. These are the type used in pocket laser pointers and CD and DVD players. They are not even remotely lethal.
The laser revolution continues, with ultrafast lasers, quantum cascade lasers, and other innovations, each enabling a brand new host of applications. So the next time you whip out that power pointer or fire up your DVD player, take a moment to reflect on what decades of scientific research has wrought, and maybe even say a quiet thank you.

It was a whirlwind Saturday at Science Online 2010 (a.k.a. Bora!Fest), where I had the chance to catch up with old friends I hadn't seen since the last Bora!Fest in 2008. It was a treat to chat with bloggy pals like Tom Levenson, Janet Stemwedel (who generously offered alcohol, wasabi peas and M&Ms to my famished self upon hearing the hotel restaurant closed seconds after I checked in), Carl Zimmer, Eric Roston, Chris Mooney, PZ Myers (yes, he and Chris were at the same conference and the universe did not implode -- imagine that!), Abel Pharmboy, and Carmen Drahl -- and of course, Bora! in all his manic glory. I finally met a few folks in person: Ed Yong, Rebecca Skloot, Kevin Zelnio, Blake Stacey (carrying an awesome cane a la Gregory House), Brian Switek, SciCurious, Skulls in the Stars, the mighty Isis, and John Timmer, to name a few. And the number of nifty new folks I met are simply too numerous to mention. Geez, people, I skip one year, and you go and add tons of smart, funny, creative people to the roster -- that's what keeps the scientific blogosphere so vibrant.
Of course, there were also lively opinionated sessions! I naturally gravitated to those centered on writing and communication, so bright and early on Saturday morning (6 AM Pacific time), I dragged my bleary-eyed carcass to hear Brian, Tom and Rebecca offer their collective wisdom on going "From Blog to Book." It's a topic near and dear to my heart, given that my new book, The Calculus Diaries, evolved directly from posts I wrote, and interactions with readers, here at the cocktail party. I generally don't like to get too "meta," but post-Science Online tends to be a time when I indulge, because sometimes a little navel-gazing can be a valuable exercise. So bear with me.
From Book to Blog
Just prior to the conference, Tom mused on his own mixed experience going from blog to book over at Inverse Square, concluding that while blogs can be valuable to writers, as a purely promotional tool, the effort probably is not worth the reward. (He re-iterated that point during the session.)
At least don’t imagine that [a] blog created simply to promote a specific book is going to do much for you. Either your book is already attracting attention, in which case the blog won’t hurt but won’t add much value for the time taken to do it right, or your book is struggling to find traction, and a brand new blog is not usually an immediately effective way to reach much of an audience. Especially if the blog is explicitly built around the work that already isn’t getting enough play.
Mid-post, he throws some gratifying and surprising props my way, in terms of how I've gone about building "pre-book buzz." It's gratifying because Tom's a good friend and an astonishingly gifted writer -- Newton and the Counterfeiter is one of the most well-researched and elegantly written scientific biographies out there, and if you haven't read it yet, Jen-Luc Piquant demands to know what the hell is wrong with you -- and hence I value his critical assessment. It's surprising because I am notoriously inept at most forms of self-promotion and buzz-building; mostly, I follow my curiosity (as time permits), and if I get the buzz-building right, it's largely by accident. Fortunately, Tom also recognizes this:
That’s how to build long-distance buzz. And what Jennifer did is exemplary in my view because it was real (as I tried to make my Newton posts as well, certainly) — by which I mean that what she wrote on the blog materially shaped what she came to think about as she wrote her book. [emphasis mine]
I would agree with Tom's conclusion that starting a blog solely to help promote your new book is kind of pointless, from both an artistic and a marketing standpoint. Granted, I started Cocktail Party Physics when my first book came out early in 2006 (see Black Bodies and Quantum Cats link under the "We Have No Shame" button in the sidebar), at the suggestion of my publisher. But it was never merely a promotional endeavor. That just seemed incredibly boring to me, so from the start I set out to make the blog a place where I could explore and indulge my curiosity. I loved having an outlet for all the nifty flotsam and jetsam I encountered as a science writer that didn't fit into paid work for professional outlets, and I loved the freedom blogging gave me to explore my unique writer's "voice." It's easier to take risks in a bloggy format, and not as big a deal if those risks fail. More importantly, I became part of a wonderful online community.
Creativity is notoriously nonlinear, but I can say with some confidence that The Calculus Diaries might never have been written had I not started the blog, and it certainly wouldn't have turned out as well. First, writing is a craft. That means you become a better writer by writing: everything I learned writing the first book fed into the second (The Physics of the Buffyverse), and everything I learned writing the second, plus innumerable blog posts, fed into writing The Calculus Diaries. Yet it wasn't just the posts I wrote about exploring calculus that materially shaped the book: it was also the give and take with readers who commented, and other bloggers who linked to the pieces and joined the conversation.
Early on in the book process, long before we met in person, Brian and I had an hour-long phone conversation about our mutual struggles with math; he's even quoted in the epilogue. And several participants in a spirited and lengthy comment thread on women and math over at Tiny Cat Pants a couple of years ago gave me permission to use their comments in the book (mostly anonymously). That's just two examples of innumerable interactions with people, both online and off, providing valuable book fodder. Heck, you guys even helped pick the book's title when we were wavering back and forth between two possibilities by weighing in with thoughtful arguments in favor of one or the other.
So this community is an invaluable resource for any writer serious about his/her craft. But you've got to be a genuine member of that community; we easily can sniff out folks who are joining just to exploit us. As Tom says, it has to be "real." (Side note: Our little cocktail party has become even more of a community with the addition of my co-bloggers last year, each of whom brings her unique perspective and writer's "voice" to the blog.)
In my keynote at Science Online 2008, I said that the blog became my "writer's lab." Brian was one of the folks who took that phrase to heart. I think it resonates because lots of people use their blog like this, whether they consciously think about it or not. Brian used Laelaps to develop his forthcoming book, Written in Stone; the blog helped him get a handle on a mind-boggling amount of material, honed his writing skills, and helped him find his voice. It's been a long journey for him, with a few discouraging hard knocks along the way, but he persevered, and I'm so happy that he's now reaping the fruits of all his hard labor.
Tom, of course, has been working on books, journalism, and science programming for awhile, so you should believe him when he says that "the conventional path to bring books to audiences is completely broken, or at least fragmented." In his view, connecting to a social network of folks who can help you spread the word is one of the few means left for marketing one's books, particularly for newcomers. The New York Times, New York Review of Books, and The New Yorker are still useful marketing outlets for authors. NPR is wonderful, because their listeners are avid readers and thus buy books. If you're incredibly lucky, you might be able to snag a spot on syndicated TV.
But for the rest of us, social networks (blogs, Facebook, etc.) are the best means available. The best way to do that, says Tom, is to create a conversation "that is about more than just the book." I would agree: I'm very supportive of my fellow writers, but nothing will make me stop reading your blog, or hide your Facebook feed faster, than if you do nothing but harp endlessly about your book. Which is why I don't harp on my own books very often, occasionally to my detriment.
If Tom is pessimistic, Rebecca Skloot is optimistic, excited to be doing books at a point in time when we're at the tipping point in terms of a new marketing model for book publishing. She's correct that publishing has been caught off guard by this failure of its publicity machine, and that there simply aren't enough internal publicists to go around. Frankly, her experiences self-marketing her book aren't especially new. Anyone who's published a book in the last 10 years already knows it's largely up to the author to make the marketing magic happen, through personal contacts or what have you, and if there's going to be any kind of book tour, it's the author who will make that happen, usually on his/her own dime.
So we are all loyal foot soldiers in the service of helping our babies find their place in the world, and it's utterly exhausting. (Eric Roston expressed relief at finally being able to go to a conference and not have to continually plug The Carbon Age.) But Rebecca has zeroed in on the problem with unusual vigor and creativity, ferociously making use of every tool at her disposal, right down to instructing her publicist how to make pitches to specific media outlets, drawing on her long career as a freelance writer. Other authors, take note and follow her lead. And show your support by buying The Immortal Life of Henrietta Lacks.
Blurring the Boundaries
I want to end with a clear statement about what Cocktail Party Physics is not: it's not professional journalism, nor was it ever intended to be. See, another session at Science Online 2010 dealt with the future of science journalism, featuring Carl Zimmer, Ed Yong, David Dobbs, and John Timmer. Carl in particular moves easily between newspapers, magazines, books, and blogs, the epitome of how the lines are increasingly blurring between these areas. People keep wanting clearly defined labels for who is a journalist and who is a blogger, but more and more of us are both at once (and authors of books besides). Some material fits better in a newspaper article; some is perfect for a magazine feature; and an amusing, yet explicit video of a corkscrew duck penis inside an artificial glass vagina is pretty much ideal for a blog, as Carl's traffic spike for that post over at the Loom should attest. (As Carl wrote, "There comes a time in every science writer’s career when one must write about glass duck vaginas and explosive duck penises. That time is now.") And every now and then, you hit on something (calculus for math-phobes!) that ends up in a full-length book.
Eversions in barriers / from blogs.discovermagazine.com/loom from Carl Zimmer on Vimeo.
I especially liked Carl's (I think it was Carl) description of this emergent media enterprise as a delicately balanced ecosystem, each segment interdependent on the others for survival. Several weeks ago, Bora! posted one of his occasional rants relishing the collapse of traditional media, in which he baldly stated that he really didn't care if the cost of the revolution was journalists losing their jobs. (I can't find the link, sorry. He's just so damned prolific.) I adore Bora!, but he's wrong about this. He should care that journalists are losing their jobs, because they are not "the Other" anymore. We are all caught up in the same ecosystem, and draconian upheaval in one segment will inevitably, in time, negatively impact the others. I agree that the revolution must, and is, occurring, and a certain degree of suffering is part of the cost, but that's no reason to abandon compassion -- particularly as the distinctions between categories continue to blur.
But if the boundaries between being a journalist or a blogger are blurring, there's still a very clear definition about what constitutes journalism, at least among professionals. One of the more heated exchanges centered on the controversial new aggregator site, Futurity -- basically a consortium of universities partnered to post their (slightly rewritten) press releases on the site with slick graphics and call it "News." Now, I understand the rationale for doing this: science coverage has declined so badly in traditional media outlets that tons of great stories get lost to obscurity. Like Tom, who was also at that session, I think there's something to be said for pooling their resources and setting up a slicker, more sophisticated version of, say, EurekAlert, which really is just a compendium of press releases, and openly states that fact.
It's a very pretty design, with some fascinating material. The problem I -- and just about every other journalist I know -- has with Futurity is the way it portrays itself as a journalistic news outlet, right down to the site design. A representative from Futurity happened to be in the audience, and insisted (a) the person who rewrites the press releases doesn't mess with the technical details, which are carefully vetted by the researchers, and (b) that they'd responded to the outcry from journalists by putting a "disclaimer" in their banner. First, while I hope it's true the researchers vet the press releases, we've all encountered tons of examples where this didn't happen. I'd be careful about making that sweeping claim, particularly with so many university partners, each with its own "best practices."
Second, and more to the point, here's Futurity's supposed disclaimer: "News from Leading Research Universities." It's the use of the word "news" that's objectionable here. In physics, common words like "force," "energy" and "work" mean very specific, well-defined things, even though non-scientists use the same words all the time in a much broader context. So, too, to a journalist, "news" means something very specific: multiple sources, no conflict of interest in the reporting, and something that has had the advantage of both an editor and a copy editor, for example. The reporter's job is to synthesize and shape the raw material into a coherent story, and especially these days, narrative frameworks and the odd bit of commentary is occasionally allowed, particularly for feature writing.
Futurity has an obvious, blatant conflict of interest and it's being disingenuous about owning up to it. What's so hard about following EurekAlert's lead and changing that disclaimer to read "Press Releases from Major Research Universities"? Their reluctance to do so suggests they know they're being a little weasel-y in their approach. Just because Fox News does it, that's no excuse to follow suit, okay?
And that's why Cocktail Party Physics is not professional journalism. It's a blog, plain and simple. It's biased, occasionally self-serving (buy my books!), often single-sourced, plus there's the occasional gratuitous duck sex video to contend with. As I told Bora! in 2008:
It takes a lot of work just to dash off a reasonably factual post at Cocktail Party Physics -- I spend a minimum of four hours on each post, sometimes longer. It would take twice as much time, at least, to bring the quality up to what I'd consider a professional standard. People sometimes compare my posts to actual published magazine or newspaper articles. They're not. They're subjective, a bit snarky, a bit unfocused, with lots of extraneous personal details woven into them. Plus, there are still typos, there's no firsthand interviews with scientists, the links are mostly to Wikipedia and a handful of online resources that I find credible, but they're not exhaustive and, well, I could be wrong!
Sometimes a blog post does turn into a nifty article, but it really is first and foremost my writing lab, and a way to stay connected with my bloggy "peeps." I think the convergence of journalism, books, blogs and other forms of media into a interconnected ecosystem is a marvelous, potentially powerful development. But we need to be very clear about the boundaries between all those formats, and label them correctly.

So, the science blogosphere is all a-flutter about this weekend's Science Online 2010, pretty much the Woodstock of Science Blogging, or as I like to call it, Bora!-Fest 2010. And oh yes, Jen-Luc-Piquant and I will be there -- I missed last year's confab due to a slight case of launching a national outreach program. I'm thrilled at the prospect of seeing all my blogging buddies again, and making new ones. Bora! even interviewed me (and numerous others) after Science Online 2008.
This time around, I'll be co-chairing a panel -- on science, Hollywood, the changing landscape of online multimedia, and what that might mean for blogging -- with the lovely Tamara Krinsky, all-around Renaissance woman of science and entertainment. Ironically, even though Tamara and I live in the same city (Los Angeles) and have several acquaintances in common, we met through Bora!, who lives 3000 miles away. That's why he's King of the Blogosphere. Our panel, called Science and Entertainment: Beyond Blogging, will be on Saturday from 2 to 3 PM and in the words of Michael Bay, it is going to be "AWESOME!"
The official description:
Over the past several years, the Internet has tangibly changed the way that movies and TV shows are produced and marketed. Blogs will call out ridiculous scientific errors found in stories and the critique can go viral very quickly; therefore, science advising is on the rise in an attempt to add some semblance of plausibility to your favorite flicks. As tools on the web continue to evolve, filmmakers and television creators are finding new ways to connect with and market to their viewers. For some shows, this has meant tapping into the science featured in their content, ranging from an exploration of the roots of the science that has been fictionalized to the expansion of a scientific topic explored in a documentary. In this session, we’ll look at how online video and social networking tools are playing a part in connecting science, Hollywood and its fans.
But we're actually hoping not to just lecture; we want you to come and join us for what promises to be a fascinating conversation. Sure, we'll both give brief presentations as an overview of the type of online multimedia currently available -- I'm excited about what's been happening in that sphere, and the stuff Tamara has told me about what's on the horizon -- and then we will open the floor to discuss how blogging fits into this new multimedia space. As that space continues to evolve and change, how should blogging change with it? What are the untapped potentials? What new multimedia formats and partnerships might be formed between science bloggers and the entertainment industry? I don't want to see blogging being left in the dust, like print media, because it gets too entrenched in the status quo. Not that this would happen: bloggers are some of the earliest adopters out there, after all. Basically it's an excuse for me to pick everyone's brain because I tend to be a bit slow up the uptake with the latest Web-trends.
In other shameless self-promotion news, I was interviewed on yesterday's Armed With Science podcast by John Ohab of the Department of Defense. Jessica of Bioephemera introduced us, and I'm so glad, because I love what he's doing with that podcast. Joining me for the interview was none other than Eureka co-creator Jaime Paglia, who gave his own take on how his show, in particular, portrays science, scientists, and the inevitable tension between idealism and pragmatism that scientists often must grapple with (e.g., they want to make discoveries and invent things to help humanity, but those same breakthroughs can be weaponized, particularly since much of their funding comes from defense). The Eureka writers are a smart, savvy bunch -- they all take after Jaime -- and now they have their own blog, too, Eureka Unscripted, for anyone who's interested in some insider baseball.
Finally, The Damn Book is finally -- finally!! -- in production. I've been working on revisions intermittently for so long, my friends started saying, "But you were revising the manuscript a month ago, weren't you? Isn't it done yet?" It's never done. But at some point you have to let your baby go out into the world, warts and all. There's no cover, or even a Web page for the book yet, but here's a sneak peek at the catalog copy and my favorite of the many excellent illustrations Jason Torchinsky created for the book:
The Calculus Diaries: How Math Can Help You Lose Weight, Win in Vegas, and Survive a Zombie Apocalypse
Jennifer Ouellette never took math in college, mostly because she—like most people—assumed that she wouldn’t need it in real life. But then the English-major-turned-award-winning-science-writer had a change of heart and decided to revisit the equations and formulas that had haunted her for years. The Calculus Diaries is the fun and fascinating account of her year spent confronting her math phobia head on. With wit and verve, Ouellette shows how she learned to apply calculus to everything from gas mileage to diet, the rides at Disneyland to shooting craps in Vegas—proving that even the mathematically challenged can learn the fundamentals of the universal language.
Those of you who've been following the cocktail party for awhile now, know the book arose out of a series of calculus-related posts I wrote starting in 2006. Here's a sampling for those who missed them:
Game ChangerThe book will be much more polished; blog posts are always the first drafts, part of my "writing lab." It's fun to see how far I've come since those early days, both in my rudimentary understanding of calculus, and in my ability to write about such an abstract subject coherently. And oh yes, there will be zombies -- even an equation involving zombies in Appendix 2: Calculus of the Living Dead. Because sometimes you just have to nut up or shut up, and do some calculus before the zombies wipe out the human race.
