If you never quite got a hang of quantum mechanics, you can take another run at it by watching four animated Ted-Ed primers, created by Chad Orzel, Associate Professor in the Department of Physics and Astronomy at Union College. He's also the author of How to Teach Quantum Physics to Your Dog. In Particles and waves: The central mystery of quantum mechanics (above), Orzel briefly traces the conceptual development of quantum mechanics, highlighting the contributions of physicists like Max Planck, Niels Bohr and Louis de Broglie.
Next up, Orzel tackles the famous thought experiment known as Schrödinger's cat, devised, of course, by the Nobel-prize winning Austrian physicist Erwin Schrödinger in 1935. For another primer on this topic, you should also check out this lesson presented by Sixty Symbols, a web site specializing in physics and astronomy videos hosted by The University of Nottingham. The two remaining videos in Orzel's series appear below.
