This book demolishes the caricature of the scientist as a "soulless hermit toiling away at abstruse problems he cannot explain except in incomprehensible gibberish". Nobel Prize-winning chemist Max Perutz demonstrates the need for an intelligent application and understanding of science in this collection of essays that ranges from science's role in food production, health, and energy to pen portraits of Fleming, Rutherford, Plank, and Weizmann. The book should be of interest to undergraduates across all science subjects and people interested in the philosophy of science.
