1. For those unaware readers, I emphasize that Einstein always denied that quantum mechanics represents a final description of physical phenomena. He believed that another, nonprobabilistic theory would eventually replace and include quantum mechanics. Einstein's discussions and debates with the quantum-theory advocates form an important and fascinating part of developments in twentieth-century physics.
