Ohh that's interesting. I've been (and still am) confused by the idea of stuff multiplying together to make something. The light example makes it clearer.

"Why not quarks" is because you can't measure quarks directly, because they don't occur in isolation; they ALWAYS occur in bound groups and will instantly transform into something else if you manage to break them apart. Electrons are, as far as we can tell, actually fundamental, instead of being made up of other things.

Oh woops, electrons are very different from protons and neutrons. Err, but what about protons and neutrons..? Do they matter? Are they part of the "volt"? Not that I know what's going on with the electron volt though :x

Wow, that really is useful when I think about it. I'm not a cashier but the first thing I'd think of for 40 cents would be 4 dimes, which I suppose is a waste of dimes XD.
