Galileo Galilei, Italian Polymath

Color enhanced engraving of Galileo Galilei (1564 - 1642), Italian scientist, illustrating him first noticing how a pendulum swings. In 1582, while Galileo was studying medicine in Pisa, he noticed a lamp swinging as a simple pendulum in the city's cathedral. His observation that it took the same amount of time for the lamp to do one swing regardless of how far it swung led him to perform experiments. These experiments demonstrated that the period of a pendulum swing is determined by its length. Enhancement of 9m5045
