The Beat of a Different Drum: The Life and Science of Richard Feynman

Few might argue that Richard Feynman was once one of many maximum American-born theoretical physicists of the 20th century, and less nonetheless might dispute that he used to be the main iconoclastic. within the phrases of the eminent mathematician Mark Kac, geniuses are of 2 types: the normal, and the magicians. Feynman used to be a magician of the top quality.

He taught himself how to make electroplated metal stick to plastic objects like radio knobs, how to keep track of time in his head, and how to make columns of ants march to his bidding. He had no difficulty learning to make an impromptu xylophone by filling water glasses; nor had he any shyness about playing them, all evening, at a dinner party for an astonished Niels Bohr. At the same time, when he was engrossed in the physicists’ ultimate how-to endeavor, the making of an atomic bomb, he digressed to learn how to defeat the iron clamp of an old-fashioned soda machine, how to pick Yale locks, and then how to open safes—a mental, not physical, skill, though his colleagues mistakenly supposed he could feel the vibrations of falling tumblers in his fingertips (as well they might, after watching him practice his twirling motion day after day on their office strongboxes).

An ordinary genius is a fellow that you and I would be just as good as, if we were only many times better. There is no mystery as to how his mind works. Once we understand what they have done, we feel certain that we, too, could have done it. It is different with the magicians. They are, to use mathematical jargon, in the orthogonal complement of where we are and the working of their minds is for all intents and purposes incomprehensible. Even after we understand what they have done, the process by which they have done it is completely dark.

A Birth and a Death Melville Feynman (he pronounced his surname like the more standard variants: Fineman or Feinman) came from Minsk, Byelorussia. He immigrated with his parents, Louis and Anne, in 1895, at the age of five, and grew up in Patchogue, Long Island. He had a fascination with science but, like other immigrating Jews of his era, no possible means to fulfill it. He studied a fringe version of medicine called homeopathy; then he embarked on a series of businesses, selling uniforms for police officers and mail carriers, selling an automobile polish called Whiz (for a while the Feynmans had a garage full of it), trying to open a chain of cleaners, and finally returning to the uniform business with a company called Wender & Goldstein.
