John Baez's Stuff
Fascinating site. This guy is really dedicated to updating his site with all kinds of cool stuff, from physics to politics to all kinds of intellectual fun. Make sure you check his blog, "This week's finds," which is an ongoing chronicle of math/phys discoveries written (almost) at the laymen's level.

Baez's physics books recommendations

Acme Klein Bottle
Will definitely fulfill all your zero-volume, non-orientable needs.

The importance of operators in quantum theory
Your one-stop source for info on Krishna operators in quantum mechanics! I wish this were a joke.

Tachyon Energy Products
Lots of really useful devices produced by Gene Latimer's innovative "tachyonization process". Just make sure you have a load of cash to drop on $500 tachyon dust. I actually produce my own tachyon products as well from my secret tachyon source, which is actually just piss in a bucket, but that doesn't matter now, does it?

Cargo Cult Science, by Richard Feynman
Great essay by Feynman on pseudoscience.
