I have been wondering this same thing - a google search directed me to your post. I'll keep an eye and post back here if I find anything. Hopefully you can do the same. I'm also very interested in finding such a source or creating one if there is a void.

For actual theoretical research in time travel, you should have a look a the work of http://www.phys.uconn.edu/~mallett/main/main.htm". Also, you might enjoy his book. Again, you should be careful how you think about claims theoretical physics, because while there is sometimes nothing to say...

Okay, gotcha! Thanks a bunch

Give this book by Blumel a look. He explains it very well, and I didn't fully understand Bell's Theorem until I gave it a look either. http://books.google.com/books?id=GOYtFsJN9dQC&lpg=PP1&dq=blumel&pg=PA182#v=onepage&q=blumel&f=false

So, if we use the ideal gas law, and divide by V^2... \frac{P}{V} = \frac{Nk_BT}{V^2} = k So we see that, if P \propto V , the expansion cannot be isothermal; moreover there must be a specific relationship between T and V? I don't really think that makes much sense that the...

I think this is just what you need: http://www.physicsclassroom.com/class/estatics/U8L1e.cfm the polarization comes from the electric dipole within the atom caused by the charge distribution

I agree, because the main part of the problem is inside the sphere. You can use \mathbf{E} = (1/4 \pi \epsilon_o) \int \frac{\rho}{r^3} \mathbf{r} dV and then break down the differential volume element to integrate

Hey there, Hyperfine splitting is not the same as polarization. Hyperfine splitting is due to a property of quantum particles called spin. This property creates "hyperfine splitting" in the energy levels of quantum systems past the fine structure that arises due to first order relativistic...

Okay, so that's the only difference thanks a bunch. I think my professor had mentioned that she was using a difference book for her notes than we had read. She hadn't been able to reconcile the difference by the end of class though--it just became a big mess. Regarding why P changes, I think...

This seems odd to me for the charge density \rho (r) = C r I don't think you can simplify to a point charge, since the potential for a point charge drops as 1/r^2 and this density says that there is more charge as you get further away from the origin. That is not the same field as a...

Homework Statement A gas expands from 1L at 1atm to 3L. Assume P is directly proportional to V. This is a simple question from my second lecture on Thermal Physics, and I have found a way to solve it after my professor made it very confusing in class. My question is more about the...
