In 1597 Galileo invented the geometric compass he called it Military compass because it could be used to aim cannons. He added more scales to the This made it useful for working out squares and cubes , multiplying, and computing compound interest. He added a curved metal arc that joined the two right angles. This modification turned the instrument into a quadrant that could be used to measure height and angles. He however made more money teaching students how to use it than he did selling the compass. He wrote a instruction manual called Operations of the Geometric and Military Compass of Galileo Galilei and dedicated it to Cosimo. Cosimo was one of his private students and the heir to the Medici family. In 1609 he heard rumors of a so called telescope so he went on to build his own. H e then proved that the moon had craters on it and was not smooth as it was thought to be. He studied the sky and made the discovery that Jupiter has moons that orbit around Jupiter. He also made the discovery that the Milky way was made up of millions of stars, each at a different difference from earth. While still observing Jupiter he wrote a sixty-page pamphlet on his discoveries. This pamphlet was dedicated to Cosimo II the head of the Medici family. He then named the moons of Jupiter the Medicean moons. Cosimo II made Galileo head mathematician to the Medici family and appointed him professor of philosophy and mathematics at the University of Pisa. At the age of forty-six Galileo returned home as the most respected scientist and notorious scientist in Italy.
