Heisenberg's Uncertainty Principle

This BBC Radio 4 podcast episode of "In Our Time" features a discussion on Werner Heisenberg and his Uncertainty Principle. Host Robert Douglas-Fairhurst, along with theoretical physicists Fay Dowker, Harry Cliff, and Frank Close, explore Heisenberg's background, the quantum theory before his contributions, and the revolutionary nature of his 1925 paper. They delve into the philosophical implications of the Uncertainty Principle, its mathematical underpinnings, and its impact on various fields, including technology and cosmology. The conversation also touches on Heisenberg's complex relationship with the Nazi regime and the ongoing challenges in reconciling quantum mechanics with general relativity in the quest for a theory of quantum gravity.
