	~~Comments and questions:~~

	*I love the article on units. I hate these units where I don't know what applies to what or what comes from what. Good idea. I'm also interested in the derivation of them. Would you be interested for me to contribute with the derivation of some of these?

	*I think Tesla are equivalent to <math>Wb/m^2\ </math>, Webers per meter squared.

	*(It doesn't really matter, but the character you're using for epsilon is actually the set inclusion operator. \epsilon or \varepsilon is technically correct.)
