At the beginning of the last century, classical physics was shaken by two great revolutionary theories. One of them, Albert Einstein's theory of relativity, revolutionized the classical concept of space-time. The second, quantum theory, was born and developed by a constellation of scientists, including Max Planck, Niels Bohr, Werner Heisenberg, and Paul Dirac. In his book, 'Thirty Years That Shook Physics,' George Gamow tells the captivating story of a brainstorming session of great minds, in which he himself played a direct role.
