One Sunday in 1583 Galileo made his first scientific discovery. During a rather boring cermony he watched one of the church lamps gently swinging. This led him to carry out further experiments to investigate the motion of pendulum .Based on this work ,Galileo formulated a law describing the pendulum swing. Later these ideas were used in the construction of the first accurate clocks.
