Clocks

A clock is a timekeeping device that works by quantifying natural phenomena. A clock operates with its own mechanisms. This means that its muse is not required in order for it to function properly. This is in polar opposition to a sundial which requires the sun to function.^{[3, p.6]}

“CLOCK, noun
1. A machine, consisting of wheels moved by weights, so constructed that by a uniform vibration of a pendulum, it measures time, and its divisions, hours, minutes and seconds, with great exactness. It indicates the hour by the stroke of a small hammer on a bell.”^[1]
Webster’s Dictionary 1828
