Most of Quantum Mechanics is about solving the Schrodinger, or similar, equations. Quite a few introductory texts take the law of conservation of energy: total energy = kinetic + potential energy, and replace the variables with operators. But none of them explain why this works. In this third video I’ll try to make operator equations seem plausible.

Global warming is here. Fortunately for the planet, we have Faith communities. All Faiths teach environmental responsibility, and most people on the planet have a Faith, therefore there cannot possibly be an environmental problem. Oh, wait a minute.
