[3][4] Galileo in 1637 described to his son a mechanism which could keep a pendulum swinging, which has been called the first pendulum clock design (picture at top). The advantage of a pendulum for timekeeping is that it is a harmonic oscillator: It swings back and forth in a precise time interval dependent on its length, and resists swinging at other rates. Whilethese clocks may have lost their popularity in the face ofmore sleek and sophisticated modern clocks, they arent dependent on either batteries or electricity (unlike almost all modern clocks), yet they are incredibly accurate. During most of the pendulum's swing the wheel is prevented from turning because a tooth is resting against one of the pallets; this is called the "locked" state. any falling object. copper, Once you have removed all four, set them aside safely out of reach of children and pets.
