The story of the word

Diogenes Laertius reports that the philosopher was named Aristocles at birth and got Plato as a nickname, for a wrestler's broad shoulders, or a broad forehead, or a broad style, depending on which ancient source you trust. The same πλατύς gives the platypus, broad-foot, and the platitude, a remark flattened by use. Mathematicians who say that numbers are discovered rather than invented are still called Platonists, and many of them are.
