Einstein Was Wrong: John Clauser on Bell's Theorem and the Nature of Reality

In this episode, we sit down with Nobel laureate John Clauser to discuss his experiments from the early 1960’s, testing Bell's inequalities and quantum entanglement. Clauser shares the story of how, as a graduate student, he proposed testing quantum mechanics against Einstein's local realism - an idea that most prominent physicists, including Richard Feynman, dismissed as a waste of time. Despite the skepticism, Clauser persisted and conducted the first experimental tests that showed quantum mechanics was correct and Einstein was wrong about quantum entanglement.

Clauser walks us through the technical challenges of the experiments, from building equipment from scratch on a minimal budget to collecting data over hundreds of hours—using punch cards and paper tape. He also discusses the philosophical implications of quantum mechanics and his current views on climate science.
