Galileo Galilei
Galileo Galilei was an intelligent astronomer, physicist, engineer, philosopher, and mathematician who contributed to scientific revolution during the Italian Renaissance. He was born in Pisa, Italy on February 15, 1564. When he was 8 years old, he and his family moved to Florence in 1574 where he was educated in the Camaldolese Monastery at Vallombrosa. He had interests and focused on Science and Mathematics until he died. Galileo Galilei is a hero because he contributed to modern physics, astronomy, and enlightening people by publishing educational books.
First, Galileo Galilei was a hero because he discovered physics theories that are still used by people. One of his famous physics theories is Motion theory. Throughout many …show more content…
In 1609, as he heard that a telescope was invented in Netherland, he created his own magnifying astronomical telescope. With that telescope, he began to observe the space. While he was observing the moon and Jupiter, “He started by observing the Moon, on which he discovered mountains and craters, not an even surface as was believed at the time. Then, on January 7th, 1610, while looking at Jupiter, he saw three small stars close to it, two to the east of the planet and one to the west. The next night he looked at them again and all three were to the west. Watching on subsequent nights he saw them in varying positions and realized that they were 'wandering' round Jupiter, as he later put it, moving around it in orbit. On January 13th, he discovered a fourth satellite or moon.” (Cavendish 8). People believed that the Moon was a perfect circle and his observation of the moon brought a shocked to people. They did not know there were a craters and mountains on the moon. Also, his observation of Jupiter was innovative. People thought all planets revolved around the Earth but Galileo found that the satellites of the Jupiter revolve around the Jupiter. Also, Galileo discovered the phase of Venus that revolves around the Sun. “And what better way to commence a celebration of Galileo's astronomical achievements than to repeat his observations of Venus. Through his telescope, Galileo found that Venus goes through a cycle of Moon-like phases, starting out as a small circular disk when it first appears in the evening sky, low in the west after sunset. In the months that follow, as Venus climbs higher above the horizon, its disk grows larger while transforming into a "half-Moon" shape -- the phase Galileo observed when the planet arrived at greatest elongation from the Sun.” (Chaple 78).
