What is it with scientists and clocks? Yes, determining the duration of phenomena is important to research, not to forget seemingly unconnected realms like navigation — Britain ruled the waves for centuries, thanks to John Harrison’s clock, accurate time-keeping being the key to determining longitude. Clocks also serve science as metaphor — start with Albert Einstein, struggling to jibe the fixed speed of light with his aborning theory of relativity, looking at the medieval clock tower in Bern and realizing that time is not fixed, but elastic. He started sending notional clocks zipping at the speed of light in thought experiments, trying to nudge us dullards into comprehension. The practical value of Einstein’s 1905 musings was dramatically demonstrated at the University of Chicago in 1942, when the first controlled, self-sustaining nuclear reaction was midwifed by Enrico Fermi. So it makes sense that another fine Hyde Park institution,...
