Episode notes
Knowledge Needs Social Support To Spread
- New knowledge required social structures that support non-survivors to think and record findings.
- Lack of communication and fact-checking slowed acceptance and correction of ideas.
Columbus Didn’t Prove The World Was Round
- The popular story that Christopher Columbus proved the Earth was round is a 19th-century myth popularized by Washington Irving.
- Educated people knew the Earth was spherical long before Columbus, so the myth misrepresents history.
Columbus’s Real Mistake Was Distance
- Columbus didn’t fail because people believed the world was flat but because he grossly underestimated Earth’s size.
- His real error was miscalculating distances, not overturning a flat-earth consensus.
