Proton:Electron mass ratio

  1. Jul 10, 2013 #1
    Reading my old copy (3rd edition) of H&R's Fundamentals of Physics and it states that no theory can predict the value of the proton:electron mass ratio to date, and that it's a "sure-fire" Nobel Prize problem. Has this been resolved yet? Can't find anything on the web.

    Thanks in advance.

    No it hasn't. None of the masses of any of the fundamental particles are currently explained by theory.
