It is the one with Bell's theorem in it. Maudlin traces how David Bohm's reframing of EPR using particle spin opened the door for Bell's 1964 proof, walked through step by step with a simple chart of coin flips: any theory ruling out "spooky action at a distance" must be deterministic, and no such local theory can match quantum mechanics's actual statistics. We cover common misreadings of Bell — that he assumed determinism (he didn't) and that his "free variables" require free will (they don't) — and close with the 1989 GHZ experiment, a cleaner, fully deterministic version of the same proof. Along the way: why Einstein's real objection was locality, not indeterminism, and why Maudlin calls the death of locality the most astonishing proof in the history of physics. Part Three is still to come. Stay tuned.
