Is anything truly random?
Summary
Host Anand Jagatia explores the nature of randomness, sparked by a listener’s struggle to create a random bathroom tile pattern. Experts demonstrate that human intuition fails to generate true randomness, as our brains seek patterns. The episode then visits a quantum physics lab in Geneva, where photon behavior proves that intrinsic randomness exists in nature, offering a definitive solution to the listener's dilemma.
