In a book infused with wisdom, wonder, and a healthy dose of wry skepticism, Nobel Prize-winning geneticist Francois Jacob walks us through the surprising ways of science, particularly the science of biology, in this century. Of Flies, Mice, and Men is at once a work of history, a social study of the role of scientists in the modern world, and a cautionary tale of the bumbling and brilliance, imagination and luck, that attend scientific discovery.
