The Strangest Man: The Hidden Life of Paul Dirac, Mystic of the Atom
Starred Review. Paul Dirac (1902–1984) shared the Nobel Prize for physics with Erwin Schrödinger in 1933, but whereas physicists regard Dirac as one of the giants of the 20th century, he isn't as well known outside the profession. This may be due to the lack of humorous quips attributed to Dirac, as compared with an Einstein or a Feynman. If he spoke at all, it was with one-word answers that made Calvin Coolidge look loquacious . Dirac adhered to Keats's admonition that Beauty is truth, truth beauty: if an equation was beautiful, it was probably correct, and vice versa. His most famous equation predicted the positron (now used in PET scans), which is the antiparticle of the electron, and antimatter in general. In 1955, Dirac came up with a primitive version of string theory, which today is the rock star branch of physics. Physicist Farmelo (It Must Be Beautiful) speculates that Dirac suffered from undiagnosed autism because his character quirks resembled autism's symptoms. Farmelo proves himself a wizard at explaining the arcane aspects of particle physics. His great affection for his odd but brilliant subject shows on every page, giving Dirac the biography any great scientist deserves.(Sept.)Copyright © Reed Business Information, a division of Reed Elsevier Inc.
