Seven self-evident truths about the world cannot be simultaneously true in quantum mechanics. Give up one, and everything falls into place. This insight provides a simple way to distinguish classical physics from quantum: if all seven hold — it's classical.
🎯 Six of the seven statements fully describe all of classical physics — from the falling apple to the rotation of galaxies. The seventh ingredient always turns out to be redundant.
🎬 A universe where all seven theses held would be classical and empty — without stars, atoms, or life.
