The History of Physics Podcast episodes
- Chadwick’s Neutron Discovery: Unveiling the Invisible Bullet
James Chadwick’s 1932 experiment with alpha particles and beryllium uncovered a neutral, mass‑bearing particle that shattered the prevailing picture of the atom. The episode traces how his careful measurements challenged existing theory, sparked new instrumentation, and opened doors to nuclear energy and weaponry.

19 min - The Archimedes Lever: From Ancient Beam to Modern Statics
Archimedes formalized the lever principle in ancient Greece, turning empirical craftsmanship into a universal law of equilibrium. By proving that force times distance must balance on either side of a fulcrum, he laid the groundwork for statics and modern engineering. This episode traces his geometric reasoning, experimental sketches, and the lasting ripple through physics, architecture, and technology.

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.
