REPOST: How John Dalton's Atomic Theory Changed Science Forever

July 8, 2026 · 12 min

Show notes

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
