This book tells about lives in science, specifically the lives of thirty from the pantheon of physics. Some of the names are familiar (Newton, Einstein, Curie, Heisenberg, Bohr), while others may not be (Clausius, Gibbs, Meitner, Dirac, Chandrasekhar). All were, or are, extraordinary human beings, at least as fascinatingas their subjects. The short biographies in the book tell the stories of both the people and their physics.
