Contrary to rumour, Isaac Newton has nothing to do with these moon dials at Queens' College. The curious panel appeared on a Cambridge wall in 1743, and to tell the time from it one did indeed need a university education. That is precisely why moon dials never became as popular as sundials: the shadow cast by the moon alone is not enough to determine the hour; a few further mathematical operations and a special scale of corrections are required. Depending on the phase of the moon, such a dial may run slow or fast by as much as five hours if the special mathematical corrections are not taken into account.
