University
He enters the University of Pisa to study medicine. As the story goes, Galileo was in the cathedral at Vallombrosa when he observed a lamp hanging from the ceiling swaying with perfect rhythm. He was fascinated that the lamp took the same amount of time to swing no matter how large the range of swing. He later would apply his theories of pendulums to clocks. -
Interest in mathetmatics
Galileo, fascinated by mathematics and geometry, starts taking classes from Ostilio Ricci -
FAILS
Galileo, not completing his degree, is forced to leave the University because of lack of funds. He returns to Pisa. -
ESSAY
He publishes an essay on the hydrostatic balance, a device to measure the mass of objects. -
Publishes paper
He publishes a paper on the center of gravity in solids and is awarded a position as lecturer at the University of Pisa. -
Galileo THEORY
Galileo works on his theory of motion. Aristotle had said that bodies of different weights fall at different rates, but Galileo did not believe this. -
Galileo gets Awarded
Galileo applies and is awarded the chair of mathematics at the University of Padua, where he remained until 1610. Padua is where Galileo did the majority of his work. -
Galileo writes a letter
Galileo writes a letter to Johannes Kepler supporting his heliocentric universe theory over that of Aristotle. Galileo would have published, but he was afraid of ridicule -
Publishes theories
Galileo publishes his theories, now called the theory of uniform acceleration. He proved that all bodies, regardless of their weight, fall at an equal rate, in the absence of friction. Also in this paper he stated that a ball thrown in the air follows a parabolic path. -
Telescope
Galileo learns of the recent invention, the telescope. He returned to Padua and is able to improve the magnification of the telescope he bought to 32 powers. -
Galileo makes many observations
Galileo makes many different observations about the solar system, using his new telescope -
Finally excepted
After being so warmly accepted at Rome, Galileo writes three letters to formally take his position on the heliocentric theory of the universe. His main reason for believing Kepler and Copernicus were his observations of sunspots moving around the sun. -
Travels back to rome
He again travels to Rome hoping to appeal the 1616 decree. The Pope does not repeal the decree, but he does allow Galileo to write on both sides of the issue, noncomentally, and equally supportive of both sides of the issue, and without making any definite conclusions -
More Discovery
Galileo makes the discovery, months before he went completely blind, that the moon makes monthly wobbles on its axis, called liberations. -
Galileo Dies
Galileo Galilei dies from a long illness.
