Thanks, DH.
My first followup would be: why does 3D space imply 1/r^2? But I am going to take a guess from your answer about W and Z Bosons:
3D space implies 1/r^2 laws is because the idea is that the interactions are mediated by force carriers, and the number of force carriers that smacks...
I am wondering why both Coulomb and Classical Gravity follow 1/r^2 laws. Weak and Nuclear force fall off at much faster distance scales! Does anyone know why it is that both Coulomb and Gravity have 1/r^2 strength, while the other forces have different distance scales?
You are correct that the equations describe fluid motion. I have a beautiful proof that solutions always exist in three dimensions, but unfortunately it is too big for this marginal comment.
I read in the Feynman Lectures, section 5-8 in Volume 2, that Coulomb's law may begin to break down at distance scales shorter than 10^-14 cm.
Feynman says that, at the time of his lecture, the question was still open. Does anyone have any new information on this question?
Thanks,

Thanks to all for their recommendations, and to whoever moved the thread to the right place. I looked for a section like this, but I'm new here and I didn't find it. :^)
Jackson's Text is not my Friend--Any E+M Text Recommendations?
Hello Everyone,
I am a first year PhD student taking E+M. We are using, as many students do, the dear text by John David Djingleheimer Jackson. He seems like a pretty righteous dude, but I'm not feeling the textbook. Does anyone...
