Who is Galileo Galilei?
I have learned a lot about Galileo Galilei in history and science class, and I think he is very fascinating, and he contributed a lot to what we know today. He was born on February 15, 1564 in Pisa. Then his family moved to Florence when he was eight years old. He met a women named Marina Gamba. He never married her but had three children, two daughters which were Virginia, and Livia. Then he had a son named Vincenzo( Machamer, Peter 2017). This is just some basic information about this man. He actually did many things, and did a lot in his life.
Most of Galileo’s early life lead up to what he is known as today. He began educating at Florence’s Vallombrosa monastery

Aristotle, a Greek philosopher, showed that heavier objects fall at a greater speed than lighter objects, and Galileo didn’t really believe this theory. So, Galileo did experiments and showed that balls of different weights and pushed went the same speed (Space.com, 14 Nov. 2017) Then, in 1609 Galileo heard about the invention of the spyglass, then he improved the spyglass and created a telescope. He then, using his new telescope found that moon wasn’t smooth and actually was rough and had mountains, he discovered four of jupiter’s moons, he discovered sunspots, and much, much more(Dejoie, Joyce, and Elizabeth Truelove). He also proposed the theory of Heliocentric, which in fact changed the way we know the solar system …show more content…
The model that everyone believed in back then was called the geocentric model. They thought that the Earth was the center of the universe because it was basically the “greatest”. Then Galileo discovered that the sun was actually the center, and the Earth moved around it. The people were not very happy when Galileo told them this, because they strongly believed in the Geocentric model. They then had Galileo go to trial to prove his theory. He in fact won the trial and we now believe in the heliocentric model today( Paul Halsall, July 1998). The trial actually said, “ That the Sun is the centre of the universe and doth not move from his place is a proposition absurd and false in philosophy, and formerly heretical; being expressly contrary to Holy Writ: That the Earth is not the centre of the universe nor immovable, but that it moves, even with a diurnal motion” This proves that Galileo did prove his theory, and changed the way we see the solar system
The Bible was one of the most important pieces of text during Galileo’s lifetime. If you went against what the Bible stated then you were considered to be a heretic. The Bible indicated that the earth was in the center of the universe and the sun and the other planets revolve around it. a theory known as the geocentric model. Many scientists argued against this theory by stating that actually the sun was in the center of the universe and the earth and the other planets revolved around the sun, this theory was known as the heliocentric model. Nicolas Copernicus was one of the first out of many scientists who publically shared this theory. Later Giordano Bruno also supported this theory and because of this the Church ordered him to be burned
After reading this letter I feel that Galileo had a very opinionated outlook on life and was heavily involved in a struggle for freedom of inquiry. Galileo was a person who had many strong beliefs and would not let people or a document have a say in what he believes.
Galileo was born in Pisa Italy on February 15, 1564. Galileo was the first born child to Vincenzo Galilei and Giulia Ammannati. His family moved to Florence Italy after living in Pisa for ten years. In Florence he received education at the Camaldolese monastery in Vallombrosa. Later on in his life he decided to study medicine at the University of Pisa to study medicine. Wh...
The main argument which Galileo’s opponents used against his theory was that in many places in the Bible it is mentioned that the Earth stands still and that the Sun revolves around it. Galileo himself was a devout Christian and did not mean to question God’s power or the Holy Writ with his work. As a result, to support his claim, he developed three logical arguments in his letter, which he backed with the opinions of leading Christian authorities, in order to prove that science can reinforce religion rather than discredit it.
Galileo Galilei, (1564-1642) an Italian mathematician and astronomer, won the respect and admiration of many people of his time because of his inventions. He constructed a military compass, an instrument for measuring the expansion of liquids, and one of the early telescopes with which he discovered Jupiter's satellites, irregularities on the surface of the moon, star clusters in the milky way and spots on the surface of the sun. He was initially skeptical of Copernicus' theory however his observations and experiments affirmed his diagram of the universe. Critics attacked Galilei's findings. They said that his "discoveries" were ridiculous to believe and that it was only is imagination or dreams. Galilei wrote a letter to Dowager Grand Duchess trying to reconcile his astronomical observations with the Bible.

The first record of the movement of the planets was produced by Nicolaus Copernicus. He proposed that the earth was the center of everything, which the term is called geocentric. Kepler challenged the theory that the sun was the center of the earth and proposed that the sun was the center of everything; this term is referred to as heliocentric. Kepler’s heliocentric theory was accepted by most people and is accepted in today’s society. One of Kepler’s friends was a famous person named Galileo. Galileo is known for improving the design and the magnification of the telescope. With improvement of the telescope Galileo could describe the craters of the moon and the moons of Jupiter. Galileo also created the number for acceleration of all free falling objects as 9.8 meters per second. Galileo’s and Kepler’s theories were not approved by all people. Their theories contradicted verses in the bible, so the protestant church was extremely skeptical of both Galileo and Kepler’s
Copernicus was a scientist and philosopher whose theory proposed that the sun was stationary, and the heavens orbit around the sun. Galileo tried to convince the Church not to abolish the Copernican theory but was told that he was not to entertain such thoughts with others.... ... middle of paper ... ...(n.d.).
Galileo used this great invention to report astronomical facts such as the moon is cover with craters instead of being smooth, the Milky Way is composed of millions of stars, and Jupiter have four moons. Perhaps the most famous discovery is the Earth revolves around the Sun and the Earth is not the center of the universe (even though he was discredited at the time).
Galileo Galilei applied the same approach the ancient scholastic had used-observation of natural events- but when his observations suggested that the earth must rotate next to the sun contrary to the deep rooted religious believe that the sun was simply moving through the ...
In 1513, Nicholas Copernicus, composed a brief theory that stated that the sun is at rest and the earth is in rotation around the sun. In 1543, just days before his death, Copernicus published this theory in On the Revolutions of the Heavenly Spheres. This theory was meant to dissolve the long lived belief in Ptolemyís theory which stated, "The earth was at the center because it was the heaviest of objects(Kagan331)." This was a common belief at that time, which supported the religious beliefs that the earth was the center of the universe and God in the heavens were surrounding the earth. Copernicusís theory was shocking, but he published such a controversial theory without sufficient evidence, it had to be considered invalid.
Why were these changes that Galileo caused so controversial in people's lives and religions, though? Why was the transition from the belief in a earth-centered universe to a heliocentric universe so hard for people, and why was the knowledge of a mathematical universe so important? The answer to these questions comes from the lives that these people led and the "truths" in which these people had their lives based. The working class of the late fifteen hundreds lived troubled lives, where infants died often, disease was usually incurable, and most people where extremely poor. The only thing these people had to believe in was God and the rest of the church. On the other hand, church leaders led extravagant lives with luscious food and housing. They did not want Galileo to change the status quo and ruin the fine lives they were leading. Galileo's testimony that the earth was not the center of the universe frightened many people into thinking that he was suggesting that God didn't exist. People weren't ready to hear the fact that they were not the center to which everything else revolved around.
Galileo was the first of six children born to Vincenzo Galilei, who was musician and music theorist. In 1583, Galileo entered the University of Pisa to study medicine.
Much to the dismay of the Church, two astronomers Galileo and Kepler had the audacity to challenge the authorities by suggesting that the sun-not the earth-was at the center of the universe. The church had a stronghold on the way the spiritual and physical world worked, so these discoveries only added to the Church’s resistance to their aims. Their discoveries came only after Kepler and Galileo began to question ancient theories about how the world functioned. These ancient truths were widely held but were inconsistent with the new observations that they had made. Kepler had discovered the laws of planetary motion which suggested that the planet would move in elliptical orbits, while Galileo followed with his discovery of the principle of inertia. Galileo concluded his finding b...
Galileo was born in Pisa, Italy on February 15th, 1564. His father, Vincenzo was a music teacher and musician. After his family moved to Florence, Galilei was sent to a monastery to be educated. He was so happy there that he decided to become a monk, but his father wanted him to be a medical doctor and brought him home to Florence. He was never really interested in medicine and studied mathematics at the University of Pisa. He was especially interested in famous mathematicians like Euclid (geometry) and Archimedes. In fact in 1586 he wrote his first book about one of Archimedes theories. He eventually became head of mathematics at the University of Pisa where he first wrote about a very important idea that he developed. It was about using experiments to test theories. He wrote about falling bodies in motion using inclined planes to test his theories.
