The optical frequency comb, a spectrum of evenly spaced, perfectly synchronized lines, became the ruler that redefined how we measure time, distance, and the composition of distant stars. Since then, the same pattern has turned up in vibrating crystals, magnetic materials, ferroelectric devices, and even cosmological models of the early universe.</p> <p>One place it had never appeared, until now: a bubbling dish of chemicals changing color.</p>
