In this title, the differences between theoretical and experimental physics are embodied respectively by Einstein and Philipp Lenard, a virulently anti-Semitic German physicist who won the Nobel Prize for Physics in 1905. Hillman describes how, unable to prove the existence of the long-popular notion of 'ether,' in debt, and jealous of the attention paid Einstein, Lenard abandoned his early admiration of the younger man and escalated his ad hominem attacks on his fellow Nobel winner for more than 20 years. The book relies in part on original works in German, thanks to Birgit Ertl-Wagner and Bernd C. Wagners translations for Hillman, adding a new perspective to the study of Einstein. It includes fascinating biographical information on both men. . . .Hillman has succeeded in his goal to 'write a historythat read(s) like a novel,' opening at the scene of a Nazi book burning. This very accessible popular science book will engage readers interested in physics, World War II, history, and biography. * Library Journal * In 1905 Albert Einstein, then a relatively unknown German theoretical physicist, published the paper that introduced his theory of relativity; that same year Philipp Lenard, an older and well-respected experimental physicist, won the Nobel Prize. Einstein, of course, went on to iconic status, but outside the scientific community, Lenard is pretty much unknown these days. What happened? In simple terms, hatred, paranoia, and bigotry are what happened. This is a portrait of a man of indisputable talents who allowed himself to become obsessed with bringing down another brilliant man, who, Lenard believed, was passing off wild speculation as science. But this was more than professional rivalry; Einstein was Jewish, and Lenard was an anti-Semite who would become one of Hitlers advisors. Was Lenards campaign part of a larger effort to rid the scientific community of Jews? Evidence suggests so, though this account also suggests that Lenard seemed honestly to believe in a conspiracy to deprive him of credit for discoveries made by other scientists. A deeply fascinating, deeply sad book that will be appeal to anyone with an interest in the history of modern science. * Booklist *
