Einstein and Quantum Mechanics: It's Not What You Think - a podcast by Michael Haack

Einstein is well known for his rejection of quantum mechanics in the form it emerged from the work of Heisenberg, Born and Schrodinger in 1926. Much less appreciated are the many seminal contributions
he made to quantum theory prior to his �final scientifi�c verdict, thatthe theory was at best incomplete. In this talk I present an overview
of Einsteins many conceptual breakthroughs and place them in historical context. I argue that Einstein, much more than Planck, introduced the concept of quantization of energy in atomic mechanics.Einstein proposed the photon, the fi�rst force-carrying particle discovered for a fundamental interaction, and put forward the notion of wave-particle duality, based on sound statistical arguments 14 years before De Broglies work. He was the fi�rst to recognize the intrinsic
randomness in atomic processes, and introduced the notion of transition probabilities, embodied in the A and B coeffi�cients for atomic emission and absorption. He also preceded Born in suggesting the interpretation of wave fi�elds as probability densities for particles, photons, in the case of the electromagnetic �field. Finally, stimulated byBose, he introduced the notion of indistinguishable particles in the
quantum sense and derived the condensed phase of bosons, which isone of the fundamental states of matter at low temperatures. His
work on quantum statistics in turn directly stimulated Schrodingertowards his discovery of the wave equation of quantum mechanics. It
was only due to his rejection of the �final theory that he is not generally recognized as the most central �figure in this historic achievementof human civilization.
