The Physics of Everything: A 50-Module Journey for the Humanist

Natural Sciences, Science

This is a 50-episode podcast in physics as a body of ideas, built for one listener: Ashlee, the most wonderful person in the world. It runs from Thales to the latest dark-energy measurements in nine parts, and it treat physics the way a good seminar treats a canon: as arguments, characters, evidence and unresolved fights

  7. Episode 30 - Uncertainty

    Episode 31

    Show notes

    Explore Heisenberg's uncertainty principle through acoustics and Michael Frayn's Copenhagen. Discover why quantum fuzziness is an intrinsic wave property, not clumsy measurement.

  8. Episode 29 - The double slit

    Episode 30

    Show notes

    Explore the double-slit experiment: physics’ most beautiful and perplexing puzzle. Discover wave-particle duality, how observation alters reality, and why quantum logic defies intuition.
