Measuring up at Center Parcs

We found this at Center Parcs near Penrith. It was a display of the heights of sports stars. It was as bilingual as ever, giving metric metres and Imperial inches. I've been reading Leonard Susskind's book Quantum Mechanics: The Theoretical Minimum. He comments on why the Planck constant is such a stupidly small number by noting that it is really because humans are too big. The units that we use are based on the size of our bodies, as shown in the picture. The most fundamental scale is really down with the sub-atomic particles. We are just too big.
