An Electron Never Runs Out of Energy. Why Not? | PROF. LENE HAU

Why doesn't an electron ever run out of energy? Classical physics predicted every atom in the universe should collapse in trillionths of a second, as orbiting electrons radiate their energy away and spiral into the nucleus. They don't. This video walks through the actual quantum mechanics that solved one of the strangest problems in physics history, from Rutherford's gold foil experiment to Bohr's stationary states, de Broglie and Schrödinger's matter waves, and Heisenberg's uncertainty principle. You'll learn why electrons behave as standing waves, why a true zero-energy state is physically forbidden, and why this single mechanism is the reason solid matter holds its shape at all.

The physics described, atomic stability, the Rutherford model, Bohr's quantization postulate, de Broglie's matter waves, the Schrödinger equation, and the Heisenberg uncertainty principle, is drawn from established, peer-reviewed twentieth-century physics. Historical attributions are presented as documented scientific history, not as quotations from any individual. REASON TO WATCH Every electron in your body is moving at roughly two thousand kilometers per second and has never once slowed down. Classical electromagnetism says that should be impossible. This video shows you exactly why the atom doesn't collapse, and why your own solidity depends on it.
