Strange Beauty

PUBLISHERS WEEKLY 4 OCT 1999

Up, down, top, bottom, strange and charm aren't just states of mind: they're kinds of quarks, the mind-bending, omnipresent sub-subatomic particles co-discovered and named in the early 1960s by the American physicist Murray Gell-Mann. New York Times science reporter Johnson (Fire in the Mind) has written a brisk, accessible life of the Nobel-winning scientist, who will turn 70 next month. Gell-Mann grew up poor in New York City, the son of Eastern European Jews. Still in his teens, he attended Yale and MIT, and soon afterward won notice for his work on cosmic rays. Gell-Mann followed up his insights about quarks with important work at Caltech and elsewhere on superstrings, supergravity and mathematical complexity. His adult life has had its hardships: his daughter gave much of her life to an American Stalinist fringe group, and his wife died of cancer in 1981. (He's since remarried.) Johnson makes clear that Gell-Mann's direct, sometimes arrogant manner could make him difficult to work with; admired by physicists, he failed to achieve the wider fame of his media-friendly colleague, the late Richard Feynman. While Johnson relates such troubles sympathetically, the story of Gell-Mann's life is in large part the story of his and others' researches and discoveries. Explaining difficult fields like quantum physics, Johnson uses as many analogies, and as little math, as he can, while trying always to give some picture of what scientific problems Gell-Mann and his fellow scientists solved. The result is a careful if colloquial biography, perfect for readers who aren't--or aren't yet--working scientists.
