- Boltzmann & the Arrow of Time: Myth, Paradox, and Legacy
Explore Ludwig Boltzmann’s 19th‑century gamble that statistical physics could explain why entropy rises, the fierce challenges from Loschmidt, Zermelo, and others, and how his ideas seeded modern thermodynamics, cosmology, and even quantum information. The episode traces the debate’s roots, its impact on science policy, and what the arrow of time means today.

24 min - Frog Leg Twitches: Galvani’s Experiment That Sparked Bioelectricity
In this episode we follow Giovanni Battista Galvani’s startling observation of a frog’s leg twitching when struck by a metal rod, the spark that pushed physics from static charge to dynamic currents. We explore how the debate with Alessandro Volta led to the voltaic pile and laid the foundation for modern electrophysiology and electrical engineering.

16 min - Copernicus Moves the Earth: What Everyone Expected—and What Nature Did Instead
In this episode we dive into Nicolaus Copernicus’ audacious heliocentric model that flipped the universe on its axis. We trace how his geometry challenged centuries of astronomy, the experimental limits of the era, and the ripple effects through Kepler, Newton, and modern cosmology.

18 min - Chadwick Finds the Neutron: Why It Still Matters
In the early 1930s at Cambridge’s Cavendish Laboratory, James Chadwick uncovered a neutral particle hidden in alpha‑particle bombardments of beryllium. His meticulous measurements proved the neutron’s existence, resolving atomic number–mass conflicts and opening doors to nuclear reactions, reactors, weapons, and modern research tools.

16 min - Heisenberg’s Uncertainty Principle: Why It Still Matters
From its birth in Heisenberg’s 1927 letter to Pauli, the uncertainty principle reshaped quantum mechanics and challenged classical intuition. The episode traces how the idea emerged from matrix mechanics, sparked debates between Einstein and Bohr, and became a cornerstone for modern technologies like quantum computing and gravitational‑wave detection. It shows why this seemingly abstract limit remains central to experimental design and theoretical insight.

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.
