| Galileo | ||||||||||||
| Galileo began his studies at the University of Pisa. While there he studied the Pendulum. In 1602 Galileo discovered that the pendulum does not depend on the arc of the swing. (The period is the time in whilch a pendulum swings back and forth.) His discovery eventually lead to his further study of intervals of time and the development of his idea of the pendulum clock. | ||||||||||||
| Galileo questioned the approach of the Aristotelians. They believed that heavier objects fall faster through a medium than lighter objects. Galileo disproved this by asserting that all objects fall at the same rate in a vacume regardless of density. Galileo wrote about his discoveries about motion in his book De Motu meaning "On Motion". | ||||||||||||
| In 1594 Galileo patented a model for a pump. While in Arsenal he was presented with the problem involving the placment of oars in galleys. He came up with an idea to treat the oar as a lever and correctly made the water fulcrum. Galileo also invented the Hydrostatic balance which he said was an accurate balance for weighing objects in both air and water. | ||||||||||||
| Galileos most famous invention was the telescope. He made his first in 1609. He made a telescope after models produced in Europe, however they could only magnify things three times. He created a telescope that could magnify objects twenty times. Galileo was about to observer things like the moon, the satellites of Jupiter and a supernova. Galileos discoveries also proved the Copernican system to be true. The Copernican system stated that the earth and the planets revolve around the sun. Before his discoveries it was believed that the world was geocentric, meaning that the earth was the center and the sun moved around the earth. galoleo got himself in trouble with the Catholic church because of his belief in the Copernican system. Galileo died in 1642. | ||||||||||||
