Episode notes
First International Scientific Quest
- The 1735 expedition was the first international scientific collaboration aimed at measuring a degree of latitude at the equator.
- That measurement settled debate on Earth's shape and enabled accurate maps and navigation.
Why Shape Of Earth Mattered
- The team measured latitude to resolve whether Earth bulged at the equator or poles, settling Newton vs. Descartes debates.
- Knowing Earth's true shape was essential for accurate sea charts and Enlightenment-era science.
Grueling Route To Quito
- The expedition sailed, island-hopped, crossed the Panamanian isthmus, and hauled instruments by mule into the Andes.
- After a year they reached Quito to begin measurements despite extreme terrain and altitude sickness.
