The Biggest Ideas in the Universe is a series of videos where I talk informally about some of the fundamental concepts that help us understand our natural world. Exceedingly casual, not overly polished, and meant for absolutely everybody. This is Idea #7, "Quantum Mechanics." We talk about the quantum recipe -- the basic ingredients of wave function and Schrödinger equation, and how they are mixed together -- leaving deeper interpretational issues for later.
