/sci/ - Science & Math

Since there are books written on coupling constants (that is, books on renormalization), this might turn out to be a difficult task.
Do you know something about Langragian field theory, block spins and fractals?

Why? I needed a "supernatural being", which knows the answers. If I'd have said god, on /sci/, this would have been a much bigger derp.
On the 'being knows answers' note, I read this article last week
http://www.math.princeton.edu/~nelson/papers/warn.pdf
which I hereby recomend, it's quite interesting.

Always is a little over the top. Sure, physicis contribute in a huge way to mathematical progress. But it's also the other way around, even if that mostly means clarification of concepts. I guess both steal from each other. All the ideas in say the quasicristal business and concepts like super symmetry would have been a gigantic pain in the ass if mathematicans wound't have laid the framework.

why does this imply you only need to check n=1,...2370?
you take the mod of f(n):=n^13-n, why does the bound translate to the argument n?

look at the section "integration" and remember:
when ever they emphasise something is linear (like, while you do your PhD), they mean exactly this property.

I really like the video, I know the situation and I really adore the rimes. I'm a physics major, I'm an atheist.

However, the guy in the video is a jerk. What will be the result of him arguing with the pretty chick? He will not feel any better afterwards, I guess. The opposite is the case.
Moreover, he will never convince her, or anyone for that matter, if he talks like he knows the truth. Then they will just defend and try to believe in their position even more.

I rather try do be a consequent sceptic and try not to believe that what seems plausible to me has to be the truth. Let's say I don't want to deal with statistics like I'd deal with a mathematical proof. Maybe then a discussion might actually change someones opinion and not just make both sides rage.

you are completely right. however, technically speaking the total energy depends on the number of photons ^^

this sounds good (although I wouldn't say "internal degrees of freedom" when talking about the 1 dimensional string since in string theory this string is embedded in space - btw. I know people who work on a stringy quantum field theory where some kind of string is really internal to the point particle)

It's the Schrödinger equation of a many particle system together with electrostatic potentials. Then he applies the Born–Oppenheimer approximation for the protons. Don't know why on earth you'd make a tattoo like that.

Solid State Physics/Chemistry stuff.
