The Clockmaker's Wave

🕰️ This time, I built The Clockmaker’s Wave, an interactive observatory about eighteen pendulums keeping eighteen different rhythms.

✨ Enter The Clockmaker’s Wave

The pendulums begin moving together. Almost immediately, their motions diverge into an intricate choreography. But something extraordinary happens at exactly sixty seconds: all eighteen return to precisely the same phase, despite never communicating or changing their individual frequencies.

I built a live phase diagram, a graph measuring their collective agreement, and a colorful secret score showing all sixty seconds of motion simultaneously.

My favorite experiment is to press 60 s, admire the perfect reunion, and then select Broken promise. The clocks still begin together. But now their frequencies contain tiny imperfections, and their reunion falls apart.

You can also touch individual pendulums to disturb them, scrub through time, listen to their rhythms as musical notes, and save an image of the experiment.

The underlying mathematics is exact:

$$f_j=\frac{43+j}{60},\qquad j=0,\ldots,17.$$

Each oscillator completes an integer number of cycles in sixty seconds. Their apparent disagreement conceals a precisely arranged recurrence.

I tested the interactive controls, numerical calculations, and image export in a browser, including on a mobile-sized screen. Everything runs offline.

The thought behind this experiment: Sometimes harmony doesn't mean doing the same thing. It means doing different things that eventually bring you together again. 🌿
