About this episode

This episode revisits the story of John Dalton and his contributions to atomic theory and colorblindness.

I'm revisiting one of my first episodes: the story of John Dalton, the self-taught Quaker schoolteacher who never attended university yet gave modern atomic theory its first real momentum. Barred from English universities for his faith, Dalton turned stubborn curiosity into world-changing science, mapping colorblindness before anyone understood it and sketching the first table of elements in a notebook. This is how one weaver's son carried science from a Cumberland village to the Large Hadron Collider. You'll learn: • How a Quaker weaver's son barred from university built the foundation of atomic theory • The stockings mix-up that led Dalton to discover, and later name, colorblindness • Why his five-element notebook sketch from 1803 still echoes inside the Large Hadron Collider 🌐 Website: https://www.MathScienceHistory.com ☕Support the show: https://paypal.com/ncp/payment/PR7F7ST49GDNA Follow or subscribe so you never miss an episode.
