You are all missing the most mysterious of all. Consider:
6([sym]p[/sym])[sup]5[/sup] = 1836.12 which is the ratio of the masses of the proton and electron.
But what of the Phi analog to that ‘mathephysical’ expression?
Well, 6([sym]f[/sym])[sup]5[/sup] = 66.54 and …
66.54 just happens to equal 6*(186234/16771), i.e. six times the speed of light in air divided by Hiyruu’s user number at the SDMB!
Coincidence? I think not.
