I know we're just bikeshedding now, but
neutrino: 0. 8 eV/c^2
electron: 510 000. 0 eV/c^2
proton: 940 000 000. 0 eV/c^2
(Note: neutrino mass is given as the upper limit.)
- _Microft 5y agoThe first value has one, the others two significant figures in this example. The decimal point is also giving a false sense of certainty when used like this. You can find more about significant figures at Wikipedia: https://en.m.wikipedia.org/wiki/Significant_figures https://en.m.wikipedia.org/wiki/Significant_figures
- panda-giddiness 5y agoYes, I know about significant figures. In fact, I considered adding a note about sig figs before deciding it was too minor of a nitpick to elaborate on. Elsewhere in this thread, people have already listed these masses to much greater precision than almost anyone needs (including me, a practicing physicist); obviously people can infer I'm rounding from context. Of course, if you were to present the masses this way without context, you should add a note about rounding.
