Galileo Galilei

He was born on February 15th 1564. He died on January 18th 1642 at the age of 77.

Galileo was a mathematics professor pioneering observations of nature with long lasting implications for the study of physics. He also constructed a telescope and supported the Copernican theory, which supports a sun centered solar system. Galileo was accused twice of heresy by the church for his beliefs, and wrote books on his ideas.


Galileo Galilei was one of the major contributions to the scientific revolution. Often called the father of modern science. He was the most accomplished scientist of his time.

Early life

He was the first of six children born to Vincenzo Galilei, a well known musician. in 1574 the family moved to Florence, where Galileo started his formal education. In 1583 Galileo entered the University of Pisa to study medicine. He soon became fascinated many subjects particularly mathematics and physics. While at Pisa Galileo was exposed to the Aristotelian view of the world. However due to financial difficulties, Galileo left the university in 1585 before earning his degree.

Key events

In 1581 Galileo enters the University of Pisa to study medicine.

In 1586 he publishes and essay on the hydrostatic balance, a device to measure the mass of objects.

From 1589 - 1592 Galileo works on his theory of motion.

In 1609 Galileo learns of the recent invention, the telescope.

From 1609 - 1610 he makes different observations about the solar system using his telescope.

  • The moon is and irregular, rough body, not smooth at scientist thought
  • The Milky Way is composed of many stars

Galileo publishes his great work, Dialogue Concerning the Two Chief World Systems in 1632.

Historical Impact

Of all of his telescope discoveries, he is probably most known for his discovery of the four massive moons of Jupiter.


In February 1633 Galileo is put on trial. All hell brakes lose, the Pope is infuriated at the content of "Dialago" and places him on trial for one thing after another. After being placed on trial at his old age, he is forced to move back to Rome. He is under suspicion of heresy. He is placed under house arrest for eight years until his death. Despite being under house arrest he continues his research.
