Why OBSERVING An Atom Changes It — Feynman's Quantum Mystery

What happens when you look at an atom? It changes. Not because you bumped it, not because your detector is clumsy — but because information about its state leaked into the universe. That single fact is one of the strangest, most experimentally verified results in all of physics, and most people have never heard it explained properly. In this video, we reconstruct the mystery from the ground up, following the evidence like detectives at a crime scene. Starting with the double-slit experiment, we track through Heisenberg's uncertainty principle, Wheeler's delayed-choice experiment, and the quantum eraser to uncover what "observation" really means in quantum mechanics. Drawn from Feynman's celebrated lectures on quantum behavior and the character of physical law. 📚 SOURCES: Richard P.
