invented the telescope." This is what most people say when

they think about Galileo. However, Galileo did not even

invent the telescope; he only made improvements to it so it

could be used for astronomy. Galileo did use it to make

many important discoveries about astronomy, though; many

of these discoveries helped to prove that the sun was the

center of the galaxy. Galileo also made many important

contributions to Physics; he discovered that the path of a

projectile was a parabola, that objects do not fall with

speeds proportional to their weight, and much more. For

these discoveries, Galileo is often referred to as the founder

of modern experimental science. Galileo Galilei was born in

Pisa, Italy on February 15, 1564. Until he was about 10

years old, Galileo lived in Pisa; in 1574 the family moved to

Florence where Galileo started his education at

Vallombroso, a nearby monastery. In 1581, Galileo went to

the University of Pisa to study medicine, the field his father

wanted him to peruse. While at the University of Pisa,

Galileo discovered his interest in Physics and Mathematics;

he switched his major from medicine to mathematics. In

1585, he decided to leave the university without a degree to

pursue a job as a teacher. He spend four years looking for a

job; during this time, he tutored privately and wrote on some

discoveries that he had made. In 1589, Galileo was given the

job of professor of Mathematics at the University of Pisa.

His contract was not renewed in 1592, but received another

job at the University of Padua as the chair of Mathematics;

his main duties were to teach Geometry and Astrology.

Galileo taught at the university for eighteen years. Galileo

made many important discoveries from the time he was born

to when he left the University of Padua,
