Hi, thanks for the replies.
clem: I understand that the electron is regarded as a point particle for simplicity sake in models. It makes it easier to do standard mathematical calculations if you consider it as a singularity. Am I right?

Hi,
I am currently a student, still grasping some basic concepts of quantum mechanics. I've been reading some books, and the model on quarks intrigue me. There's something I'll like to clarify though.
Mass
Up Quark - 1.5 to 3.3 MeV/c2
Down Quark - 3.5 to 6.0 MeV/c2
Electron - 0.511...
