Birth Date
Galileo Galilei was born on February 15, 1564 to the parents of Giulia Degli Ammannati and Vincenzo Galilei. Galileo grew up in Pisa, Italy, during the Italian Renaissance. Galileo's father Vincenzo Galilei was a seminal figure in the music life of the late Renaissance.
This event is significant because Galileo Galilei helps place improvements on physics and science that we use today.

First Important Scientific Discovery
In 1583, Galileo did experiments with pendulums. He observed that the swing remained constant as the swing grew shorter. He also observed that it would only change if the length of the string was different. This is significant because it helped Galileo design the device called pulsilogia that helped measure a patient's pulse. Source: (Hightower 14) -
Wrote First Scientific Paper
In 1586, Galileo wrote his first scientific paper describing hydro static. Galileo described how objects could be weighed in water and their density can be calculated. To experiment it, they would put a certain amount of water and then add the object to see how much the water level rises. This is significant because solved the problem that was written by Archimedes. Source: (Hightower 19) -
Portland Trade Monopoly
In 1594, English Navigator James Lancaster breaks Portland trade monopoly in India. The East Indie Company was formed to trade with the East Indies but ended up trading mainly with India. The government owned no shares and had only indirect control. The Company then struggled with financial problems. That led to the break of the Portland Trade monopoly in India. This is significant because they cut the financial problems and the indirect control had been taken care of. Source: (Boorstin 265) -
The Starving Time
The Starving Time took place in Virginia. During this time, colonists had suffered with landing on this land. They had struggled to survive and build a New Colony. Also, Native Americans helped them survive. Most of the colonists had already been weakened and extremely sick. This is significant because during this time, more than hundreds were killed because of starvation. Source: (Carlisle 4) -
New Telescope
In 1609, Galileo Galilei created a telescope where he could see objects three times closer. He then created another telescope that year that was more accurate and its image was enlarged sixty times. This is a significant event because his creation of a better telescope allowed him to prove Aristotle and Ptolemy's theories incorrect.

Discovery of moons
In 1609 from November 30 to December 18th, Galileo Galilei had been looking at the moon through his telescope. Galileo had discovered that the moon wasn't a flat surface and that it actually has mountains and craters on it. This is significant because this had proved Aristotle and Ptomely's theories wrong. Everything he discovered, he wrote in his book,"The Starry Messenger". Source: (Swisher 86) -
All Planets Revolve around the sun
On January 7, 1610, Galileo Galilei looked at Jupiter and saw four moons. Galileo also observed Venus and found out that it has phases like the moon. He had also discovered that Venus is much larger in a crescent phase than when almost full. This is significant because it came to Galileo's theory that all planets revolve around the sun.

Sidereus Nunclus
In March 1610, Galileo's account of his visions through the telescope (Starry Messenger) was published. In this was all of his findings, Galileo's observations on the moon's surface and stars in the Milky Way, and his newly discovered moons called Medicean Stars. This is significant because it was an instant success and it was observational evidence that we live in a Copernican Solar System in a gigantic universe. Source: (Swisher 88) (Hightower 53) -
Letter
In 1613, Galileo Galilei was trying to write a letter to prove something. He was trying to attempt to show that Copernican theory fit both Catholic doctrine and Biblical interpretation. He was trying to prove that his theory didn't go against the bible. This is significant because he was a proving Catholic and wanted to show that his theory didn't go against anything Catholic or anything in the Bible. Source: (Galileo 119) -
Treaty of Xanten
In 1614, the Treaty of Xanten was passed. Julich-Cleves was then passed and divided between Brandenburg and Neuburg. The treaty ended the War of the Jülich Succession and all hostilities between the two rivals. This is significant because it caused a stop to all the tension in the war of the Julich Succession.

Mayflower Compact
The Mayflower Compact was signed aboard the Mayflower as she sat at the anchor off Cape Cod on November 11, 1620. It was a signed agreement to ensure peace between the two groups carried by the Mayflower ship to America. The Mayflower Compact specified basic laws and social rules for the new colony. This is significant because it contains extremely important concepts that helped shape the historical shape of America. Source: (Carlisle 3) -
Dialogue Concerning the Two Chief World Systems
In 1632, Galileo Galilei published Dialogue Concerning the Two Chief World Systems. It was claimed to be neutral on the astronomical debate. Its failure to do so was but one of the objections raised after publication. When Galileo published it reacted within in five months, and in 1633 his famous trial and recantation took place. This is significant because it had led to his famous trial in 1633 called "The Trial of Galileo Galilei". Source: (Galileo 119) -
Trial of Lancashire Witches
In 1633, the trial of Lancashire witches took place. It was all based on activities following the English coronation of King James I, and as a result of the fear instilled by the Guy Fawkes Gunpowder Plot. Those events were 1602 and 1605 and culminated with the executions in 1612. The footnote of all this happened in 1633 with the execution for witchcraft of Jennet Devize. This is significant because they are the best recorded and most famous witch trials in England. Source: (Boorstin 287) -
Two New Sciences
In 1638, Galileo Galilei's discourse on "Two New Sciences" was published. It was mainly devoted to the treatment of uniform and accelerated motion. Galileo, "composed a treatise on continuous quantity as early as 1609 and had devoted much further study to the subject". This is significant because it gave us more information on more physics that he experimented with. Source: (Galileo 119) -
Charles I March
In 1642, Charles I marches to Westminster to arrest the five members of the Commons. However, Charles' attempt fails. Charles then flees with his family to Hampton Court. This also leads to Queen Henrietta Marie leaving England for Holland. This is significant because his march had led to the danger put on his family, then it had given danger to Queen Henrietta Marie causing her to leave England. Source: (Boorstin 290)
