Re: Mass ratios

  1. Feb 17, 2005 #1
    Is there any reason why an electron is 1084(I think that's right) times smaller than the mass of a neutron. is there any mathematical or "physical" reason why this works for atoms and if so what would be the consequences of a proton having half that mass but with the same ratio to an electron or indeed having a different ratio? Would there be any real world implications or is the ratio important rather than the masses?

    Is this a 'it just is' answer question?

    It is an unaswered question. Wilzeck's "Mount Planck" is a good sketch of the issue.

    Compare the mass of an electron with the masses of up and down quarks and tell me whether the ratio is that "impressive"...

    BTW:~1039.6 is the number you were supposed to write...

    The reason I asked was?

    At work I'm talking to a guy who thinks he know's why it is the masses are of that ratio, so I thought I might try and find out if anyone else had any insight, he's a clever guy but he won't tell me his ideas, he's a Dr on a mission, he'll be gratifeid to know that the science community know's not why, not surprisingly; I thought I'd find out if anyone else had approached this problem, I see that they haven't, good I'd love to work with a Nobel prize winner:) just kidding but he thinks he's close to finding the answer, if he is great but I doubt it; thanks for replying to the post anyway,all answers greatfuly recieved

    godzilla7, please redirect your friend to my wiki page

    for info in different amateurish approaches.

    The most current measured values are always in the "particle data group" website http://pdg.lbl.gov/
