The radius of a proton, he found, was about 0.879 femtometer—about one ten-billionth the size of a droplet of mist and square in line with previous measurements.

This “proton radius puzzle” suggests there may be something fundamentally wrong with our physics models. And the researchers who discovered it have now moved on to put a muon in orbit around ...

Rutherford made a series of discoveries about the nature of atoms and, working with colleagues Hans Geiger and Ernest Marsden, presented a planetary model of the atom in 1911. In it, he laid out ...
