Oliver Sacks's luminous memoir charts the growth of a mind. Born in 1933 into a family of formidably intelligent London Jews, he discovered the wonders of the physical sciences early from his parents and their flock of brilliant siblings, most notably "Uncle Tungsten" (real name, Dave), who "manufactured lightbulbs with filaments of fine tungsten wire." Metals were the substances that first attracted young Oliver, and his descriptions of their colors, textures, and properties are as sensuous and romantic as an art lover's rhapsodies over an Old Master. Seamlessly interwoven with his personal recollections is a masterful survey of scientific history, with emphasis on the great chemists like Robert Boyle, Antoine Lavoisier, and Humphry Davy (Sacks's personal hero).
