Sample text

The tricky part would be figuring out the crown’s volume. Because it was not a geometric shape, like a cube or a ball, Archimedes did not know how to figure out the crown’s volume. He had to figure out what to do without destroying the crown in the process. Then, the great mathematician devised a solution: He would submerge the crown in water and then do the same with an equal mass of pure gold. The amount of water displaced each time A New Direction could then be calculated. If the same amount of water was displaced, then the density of the metal in the crown would have to be equal to the density of pure gold and the crown would be genuine.

He was also developing his own, unique approach to his education. For one thing, he was becoming extremely opinionated. Galileo would study the texts, such as the writings of the ancient Greek philosopher and scientist Aristotle, as all of his fellow students did. Galileo did not automatically accept the conclusions and theories that Aristotle promoted, however, because Aristotle never experimented. To Galileo, Aristotle had never proved anything. For this reason, it became important to the young Italian student to question the theories of Greek scholars such as Aristotle.

53 Galileo 54 According to one story, Galileo did, in fact, come upon an answer. ” 19 Galileo would test the theory using cannonballs, but he had to find a place where he could drop them from a height of 150 feet. He chose the Tower of Pisa, already an important landmark in Pisa. The leaning bell tower was perfect for Galileo’s experiment. Aristotle had written of dropping balls a distance of 150 feet and the tower stood just over 180 feet in height. Galileo announced to everyone at the university that he intended to perform an experiment to prove Aristotle wrong.
