comment Entangled electron-positron pair
@genneth I don't quite get it. Is it possible to design some kind of experiment to prove such wavefunction really exists?

comment Books that every physicist should read
Most of the books listed are more related to theoretical physics. I wonder if there is any "bible" for experimental physics?

comment How to determine the mass of a quark?
Thanks for all comments above and the re-tagging. @genneth, you took the words right out of my mouth. There has to be some experiment from which scientists can calculate or estimate the rest mass of quarks. I can hardly imagine those quark's masses listed in my textbook is simply derived from theories, via pen and paper, without any experimental verification.

comment How to determine the mass of a quark?
I meant we have never found a single quark. They always appear in pairs or trios (hadrons), because of color confinement.
