The History of Physics Podcast

This episode traces the journey of the Mohist camera obscura, an early pinhole experiment recorded by 5th‑century BCE Chinese scholars. It explores how this simple observation led to systematic studies by Alhazen and Kepler, ultimately feeding into Maxwell’s field theory and reshaping our understanding of light.

Explore how Democritus’ bold claim that matter is built from indivisible atoms and void laid a mechanistic worldview that later powered Newton, Dalton, and quantum physics. We trace his philosophical laboratory to modern atomic theory, revealing why this ancient speculation still fuels curiosity today.

In this episode we investigate the legendary experiment where Galileo supposedly dropped two balls from the Leaning Tower of Pisa to prove that weight does not affect acceleration. We trace the story’s origins, debate its historicity, and explore how it helped overturn Aristotelian physics, set the stage for Newton’s laws, and shaped modern experimental methods.
