Episode notes
Quartz Crystals in Timekeeping
- Quartz crystals vibrate at a consistent frequency when electricity is applied, making them suitable for timekeeping.
- This piezoelectric effect allows quartz clocks to be more accurate than traditional mechanical clocks.
Clock Drift and Stability
- Clocks can drift, gaining or losing time due to imperfections in their mechanisms.
- Atomic clocks aim for stability, measuring a second identically now and in the future.
Cesium-133: A Universal Timekeeper
- Atomic clocks use cesium-133, chosen for its consistent frequency reference, to maintain accuracy.
- This eliminates human error and ensures consistent timekeeping across the universe.
