well, that last one is a valid question as written. while quantum field theory (at least my experience with it) is excellent at predicting things like the electron's magnetic moment, it's not so much predicting the future. i suppose general relativity is closer in that you can extract geodesics, which will give you trajectories. still, that's a fairly limited portion of the future.

I like the idea of a "Physics Friend Network".

I was on OKCupid as well - Its just as bad. I'll reiterate that unfortunately - you really do get what you pay for. The pay websites do a really good job of filtering out the crazy and less than intelligent people out there.

Allyson: Carl Zimmer (over at The Loom) would probably love to add that tattoo to his Science Tattoo collection.

Is that an atomic nape I see?

That is a truly awesome tattoo.

The first tattoo I've ever seen that I've liked....! As for the email exchange...I'm recovering from a prostate operation and it's done wonders for my morale...still chuckling!!

Cesium, highly reactive with water. All of those metals in that column are. Interesting pick.

I'm with Terryp! Your confused suitor stumbled across a very insightful question. I'd say the primary goal of any theory of physics is to develop a mathematical formalism to describe the current state of the physical system under consideration and a mathematical formalism for propagating that forward in time. Whether or not the theory properly describes the future (insert caveats about chaos and computational complexity) is an essential test for any theory of physics.

I'm perplexed by the Li tattoo. I understand why the nucleus wouldn't be drawn to scale (so as to make it visible), and why the electron orbits would be drawn classically (it's hard to draw overlapping 3-D wavefunctions), but I'm still confused about what's going on with the electron orbits. They all appear to have nonzero orbital angular momentum and similar radii. Have the two s-shell electrons been promoted to p-shell orbits? That's a mighty exotic state, as it's difficult to excite and I'd expect it to ionize on sub-ns timescales. That's a pretty cool state to get.

Sick Tattoo That makes me want to get a science related Tattoo now!
