who was richard feynman
All mass is interaction. Richard Phillips Feynman (May 11, 1918 â February 15, 1988) was an American physicist. In the International Phonetic Alphabet his surname is rendered [ËfaÉªnmÉn], the first syllable sounding like fine. Many of the quotes here were delivered by Feynman orally in lectures or interviews. Published versions of these oral statements are necessarily cleaned up by editors, and different editors might clean up the same statement differently.
