Reverberation and Sabine's formula: a clap in a church, then curtains

Afterwards you can compute a room's reverberation time with Sabine's formula, measure it from a decay curve, and tell echoes, flutter, and reverberation apart.

Plucked string harmonics: why a pluck at a third has no third harmonic

Afterwards you can expand any string shape in a Fourier series, follow a pluck's kinks with d'Alembert, and predict its missing harmonics and its brightness.

Metronome synchronization: why five on a rolling board fall into step

Afterwards you can explain why coupled metronomes lock in step or in opposition, measure it with the Kuramoto order parameter, and find the coupling threshold.
