Our ancient ancestors first made measurements using their hands and feet or a primitive calendar painted on cave walls. But once humans started building grand projects for their gods, such as the sun God Ra, things needed to be more exact. The cubit rod made sure the Egyptians' pyramids met at the top, and their sundials brought order to their expanding Empire. Yet our 'accurate' modern measurements like the meter are based on faked figures from one of the most influential cover ups in history, and the variable rotation of the planets means 'time lords' have to sneak extra seconds into our clocks now and then. Can scientists solve the problem?
