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.

In 1916, Einstein predicted the existence of gravitational waves, however, it took almost a century for researchers to detect them. In this episode of the 632-nanometer podcast, the team has a fireside chat with Rainer Weiss, the man behind the Laser Interferometer Gravitational-wave Observatory and winner of the Nobel Prize in Physics for the observation of gravitational waves.
What are gravitational waves, where do they come from, and why are they so difficult to detect? What detection approaches were considered and how did they eventually succeed? In this podcast, you will find the answers to these questions and hear many other insights from Rainer Weiss about science and life in general.
We also discuss space-time distortion, Einstein's theories, the evolution of black hole theory, the pioneering efforts of Joseph Weber, the limitations of early detection methods, the discovery of the interferometry approach, the significance of inflation, technological challenges faced by current detectors like LISA, the role of Richard Isaacson in securing LIGO's success, proposals for moon-based colliders, the role of AI in physics, the operational and financial challenges in large-scale scientific projects, and lots of strategic advice for future researchers.
