🕰️ Big Ben Great Clock: Pendulum, Escapement and Bell Acoustics Lab

Explore how the Great Clock of Elizabeth Tower keeps time with a 4-second compound pendulum, a gravity escapement and penny regulation, then strike the Great Bell and quarter bells and hear how their partials fade with distance. The simulation integrates the non-linear pendulum equation and compares measured seconds-per-day shifts with analytic formulas.
