In vivid and beautiful language, this book tells the stories of scientists at work, for example Newton who is dedicated to physics, alchemy, theology and politics; Rutherford who discovers atomic structure and Einstein who is stubbornly against the concept of black hole. He also recalls his teacher and friend Teller and Feynman, who are also brilliant scientists. This book is full of interesting anecdotes and profound observation about human nature and reflects the spirit of suspicion of the author.
