Hah, was this spurred because of that thread I started about the electron? On that subject, by the way, I really only meant what I said in the most rudimentary way. We've observed it's effects obviously, but not it [i]itself[/i] and, in fact, it could be infinitesimally too small to ever observe. I wasn't saying it didn't exist, merely remarking on how it's impossible to see it.
