⏱️ Nuclear Clock Lab: Thorium-229 vs Atomic Clocks, Frequency Stability and Allan Deviation

Explore how clocks are compared: build a noisy oscillator locked to an atomic or Th-229 nuclear reference, watch the Allan deviation fall as the square root of 1/tau, and see why a nuclear clock could beat atomic clocks.

⚙ Under the hood

Lock a noisy oscillator to a caesium, strontium, Al+ or projected Th-229 reference, build the Allan deviation live and check the tau^(-1/2) law, then race clocks over 10^9 years; unlike the existing caesium-fountain sim it compares four clock types, the quantum-projection-noise limit and the nuclear-clock hypothesis.
