In 1905 Albert Einstein committed scientific heresy. He proposed that light could be thought of not as a continuous phenomenon stretching through space but as a collection of particles. Yet even after this suggestion had been finally developed into the Quantum Theory of Light, Einstein could not accept the random nature of it.
John Maddox discusses Einstein's disbelief of the Quantum Theory with Martin Klein , Professor of Physics and the History of Science at Yale University, and Abraham Pais. Professor of Physics at the Rockefeller University.
