I am bumping this thread because I was wondering it myself. I can't claim the mathematical chops for understanding Noether's theorem, but perhaps someone can give me some idea/well-informed speculation about this question, or even if it's sensible. Leonard Susskind is perhaps the most...

Light (photons) certainly can be stored, however, it's not like the photons are a bunch of marbles you can carry around in your pocket. To get a more satisfactory answer, you should try asking more specific questions. Try to be as accurate as you can with the terminology you're using. Ask...

http://www.technology2skill.com/science_mathematics/vector_analysis/vector_picture/curve_surface_integral_first.png This might be a helpful picture: Here k is a flux vector, and n is the unit vector normal to the surface. The reason why dA is a vector quantity is the amount of electric flux...

great stuff!

So with my limited understanding of particle physics, I've gathered that the the jist of a collider is you accelerate (usually two) beams of charged particles towards each other so that they collide with the highest possible energy. The more energy you use, the more interesting your results will...

So I was reading up on the Pythagoreans, and I came across this page: http://www.math.ufl.edu/~rcrew/texts/pythagoras.html . I don't see the reasoning behind this statement. I tried some simple algebra on this statement and couldn't get Pythag to fall out of it. Can someone figure out a...

I second that, you might even learn some new mathematics in the process!

I'd get a used copy of University Physics, probably an older edition would be cheaper. You will likely have to buy this text at some point as an undergrad.

Cool, this does explain the relationship between an AC's frequency, and the current density throughout the wire. I suppose I have a more general question as well. The above wikipedia article states that So more generally, why would (direct) current be evenly distributed throughout a wire, and...

why doesn't charge only flow along the surface of the conducting wires in low frequency AC circuits? Intro to E & M teaches you that the E-field inside a conductor must always be zero (at least in an electrostatic configuration), so why does this change in (certain) electrodynamic cases?

I find randomness to be a very clear concept, at least when I think about it in terms of Kolmogorov complexity. I wonder if Clausius, Boltzmann, Gibbs, and others would have formulated entropy differently if this mathematical tool had existed a century earlier. KC turns out to be another way...

Great question, I might be wrong here, and I don't think this is a complete or satisfying answer by any means but: the speed of light in a vacuum, c, is defined as c = 1/√ε_{0}\mu_{0} where ε_{0} is the permittivity of free space aka the electric constant, and \mu_{0} is the...
