Galileo, without any option, is forced to leave the University of Pisa due to the lack of money required to fund his education. He didn't complete his degree when he left.
-
Galileo publishes an essay about the Hydrostatic Balance, a balance that can accurately determine the weight of an object submerged in water.
-
Galileo publishes a paper discussing about the centre of gravity in solid objects. After that, he was awarded a position as a lecturer from his former university.
-
Galileo is awarded the position of chair of mathematics in the University of Padua, which he will eventually spend most of his life in.
-
Galileo publishes the Theory of Uniform Acceleration, a theory that he worked on for more than 3 years. It proved that all objects, regardless of their weight, fall at the exact same speed if there's absolutely no friction.
-
After hearing about Hans Janssen's latest invention, the telescope, Galileo decided to try to improve it and apply it to astronomy. In the end, Galileo was able to improve it by 32 times.
-
He leaves Padua to become the first ever Philosopher under Cosimo II de' Medici, the grand duke of Tuscany. That allowed him more time and funds for his works and projects.
-
Galileo publishes a pamphlet involving his findings about space through his newly improved telescope. In this pamphlet, Galileo writes about his early discoveries about the Earth's imperfect moon, Jupiter's moons and the stars that aren't visible to the naked eye.
-
Galileo demonstrates the telescope to Rome
-
Galileo, after Rome accepting his discoveries without conflict, decided to write three formal letters to officially declare what he believed our Solar System looked like: the moon revolving around Earth, and the Earth, along with the rest of the planets, revolving around the Sun.
-
Galileo decided to write his three letters about his belief on how the Solar System looked like in Italian, which resulted in a larger and broader audience instead of religious and scientific communities. This lead to overall conflict between the followers of the writings of Aristotle and Galileo.
-
Galileo temporarily retires to Bellosguardo, an area near Florence.
-
Eventually, the followers of the writings of Aristotle managed to convince the Church that Galileo was going against the scriptures, which lead to even more conflict with Galileo. The Church then decided to completely ban Galileo's writings from the public, and warns him not to "hold or defends his doctrines".
-
Galileo writes and publishes a book called 'The Assayer' in Rome. It debates the difference between primary properties compared to other properties. In this book lies one of his most famous quotes of his lifetime: "The Book of Nature is written with Mathematical characters", which was the first look at nature at a mathematical way instead of the more common philosophical way.
-
Galileo travels back to Rome in hopes to repeal the ban of his writings in Rome. The Pope however, did not agree to this issue and refused to remove the decree. In spite of that, the Pope does allow Galileo to write about the heliocentric theory, but he cannot have a definite conclusion and opinion on the matter.
-
Galileo publishes a book called 'Dialogue Concerning the Two Chief World Systems - Ptolemaic and Copernican' with the consent of the Pope. It was written as if two men were discussing and comparing the Copernican system to the traditional Ptolemaic system.
-
The Pope, infuriated by the contents of Galileo's latest book, placed Galileo under house arrest for the rest of Galileo's life.
-
Galileo, despite still being under house arrest, publishes his final book called the 'Dialogue Concerning Two New Sciences'. It was a scientific testament covering all his discoveries revolving around physics throughout his life.
-
Galileo, after retaining well-being for most of his life, catches a long-lasting illness that finally lead to his death.
His tomb is located in the Basilica of Santa Croce, Florence, Italy
