21 min - Heisenberg’s Matrix Mechanics: How 1925 Ended the Planetary Electron Model
In 1925 Werner Heisenberg abandoned the classic picture of electrons orbiting nuclei, replacing it with matrix mechanics that treated observable quantities as time‑varying matrices. This breakthrough resolved the hydrogen atom’s radiation paradox, introduced the uncertainty principle, and laid the groundwork for modern quantum physics. The episode follows how a windy island and a young physicist’s fresh perspective reshaped our understanding of matter.

19 min - Shadow on the Sun: How Eratosthenes Measured Earth's Size
In this episode we follow ancient Alexandria’s library to uncover how Eratosthenes used a simple stick and the sun’s shadow to calculate the globe’s circumference. We explore his methodology, the cultural context of Greek science, and the lasting legacy that paved the way for modern geodesy and GPS.

17 min - When Uranium Split: Meitner & Frisch Decode the First Nuclear Breakthrough
In December 1938, Otto Hahn and Fritz Strassmann’s neutron‑bombardment of uranium produced a surprising barium residue, hinting that the heavy nucleus might be splitting. Lise Meitner and her nephew Otto Frisch quickly showed that this fission released enormous energy via E=mc², laying the groundwork for reactors and atomic weapons. This episode traces how a single experiment reshaped physics, politics, and society.

About The History of Physics Podcast
From the publisher's feed
Explore the extraordinary history of physics, from the earliest attempts to explain motion, matter, light, and the heavens to the discoveries that transformed our understanding of space, time, energy, atoms, and the universe. The History of Physics Podcast follows the thinkers, experiments, equations, instruments, institutions, and scientific revolutions that built modern physics across thousands of years.
Episodes trace ideas from ancient Greek natural philosophy, astronomy, and mechanics through the Scientific Revolution, Galileo, Kepler, Newton, thermodynamics, electromagnetism, optics, statistical mechanics, relativity, quantum theory, nuclear physics, particle physics, cosmology, and the search for deeper laws of nature. The show also explores famous experiments, rivalries between scientists, failed theories, technological breakthroughs, major laboratories, mathematical innovations, and the historical circumstances that changed the direction of scientific thought.
Whether you are interested in Newton and Einstein, quantum mechanics, black holes, electricity, atomic theory, space exploration, or the people behind the equations, the podcast tells the human story of how physics developed and why its discoveries changed civilization. The History of Physics Podcast is hosted by Josh Linsk.
