18 min - Earth Spins, Stars Stay Still: Aryabhata’s 5th‑Century Revolution
Aryabhata of ancient India proposed that the Earth rotates once every sidereal day—a radical idea that predated Copernicus by over a millennium. His mathematical tables and precise calculations challenged prevailing geocentric models, influencing later astronomers in the Islamic world and laying groundwork for modern concepts of reference frames.

20 min - Carnot's Thermodynamic Ceiling: How 1824 Set the Limits of Heat Engines
In this episode we follow engineer‑turned‑physicist Sadi Carnot as he discovers that heat engines have a theoretical efficiency ceiling tied to temperature differences. His 1824 manuscript, though initially overlooked, laid the groundwork for the second law of thermodynamics, entropy, and modern power generation.

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.
