Episode notes
Why Standard Units Emerged
- Early units were local and inconsistent, which hindered trade as regions grew connected.
- The French Revolution created a push for a universal, decimalized system to standardize measurements.
Pendulum As A Failed Meter
- The first meter idea used a pendulum half-period equal to one second but failed due to Earth's variations.
- They abandoned it because a pendulum's period changes depending where you are on Earth.
The Paris Meridian Origin
- France defined the meter as one ten-millionth of the distance from the North Pole to the equator through Paris, despite limited data.
- They later used a platinum-iridium prototype bar stored in Paris as the legal meter standard.
