Who is Galileo Galilei? He is an astronomer and the founder of modern experimental science. Galileo made observations of sunspots, Saturn, and Venus. He noted that, much like the moon, Venus progresses through phases.He also discovered the law of falling bodies as well as the law of pendulum. Galileo designed a variety of scientific instruments. He developed and improved the refracting telescope, though he did not invent it.
Galileo Galilei was born in Pisa on Feb. 15, 1564. In the early 1570's, his family moved to a new location. Galileo went to school in a monastery in Florence. Galileo's father wanted his son to be a doctor. For the next four years, Galileo studied medicine and the philosophy of Aristotle. In 1585, he convinced his father …show more content…
The problem, as he saw it, was the Aristotelian theory of motion. The theory referred all motion to a stationary Earth at the center of the universe, making it impossible to believe Earth actually moves. Galileo went to work to develop a theory of motion consistent with a moving Earth.
Among the most important results of this search were the law of the pendulum and the law of freely falling bodies. Galileo observed that pendulums of equal length swing at the same rate whether their arcs are large or small. Modern measuring instruments show that the rate is actually somewhat greater if the arc is large. Galileo's law of falling bodies states that all objects fall at the same speed, regardless of their mass. It also says that, as bodies fall, the speed of their descent increases uniformation.
Because of Galileo's advanced age and poor health, the church allowed him to serve his imprisonment under house arrest in a villa outside Florence. There, he passed the remainder of his years in isolation. Eventually, he became blind. But he managed to complete his final scientific masterpiece, the Discourse on Two New Sciences, published in 1638. In this work, Galileo provided both a mathematical proof of his new theory of motion and an original study of the tensile strength of materials. Tensile strength is the maximum stress a material can withstand before breaking. He died on Jan. 8,

Galileo was an Italian scientist that built many theories about astronomy. One of Galileo's theories encourage the belief of the heliocentric theory which states that the earth in the center of the universe. This statement goes against what the Catholic Church had to say. The Church believed in the geocentric theory is the correct way on how the earth was formed. This caused havoc in
Galileo Galilei, a renowned astronomer and mathematician born in 1564, was one of the most controversial people of the Renaissance Period due to his objection with the geocentric theory, which was accepted by the Church. Galileo was persecuted and excommunicated because of his theory that the Sun was at the center of the solar system instead of the Earth. He was even threatened with torture and death unless he renounced his beliefs. He was put on trial on June 12, 1633 in Rome, and was forced to apologize for committing heresy. After the trial, Galileo was placed on house arrest for the rest of his life and one of his books, Dialogue on the Great World Systems, which compared the Copernican heliocentric theory to the traditional Ptolemaic geocentric system, was put on the index of banned books, regulated by the Inquisition.
Before the Scientific Revolution, the Church had lots of power. This meant that whatever the Church said everyone believed without questioning what the church said. As the scientific revolution started people started to question the church’s reasons behind their actions. Galileo thought that without reasoning behind the Church's decision how do you know they are the right decisions. Instead of blindly following whatever the Church said Galileo came up with his own ideas.
Galileo began work on critiquing Aristotle’s manuscript, De Motu. He disagreed with Aristotle’s argument that there are for kinds of terrestrial matter and only has two forms. Galileo, using an Archimedian model, describes that there is only one form of matter, which is heavy. Light matter is a form of heavy matter that dispels other bits of matter or energy that then makes the heavy matter rise in comparison to the dispelled matter. In order for him to accurately represent the claims that he made, he tried using weight and a balance; however, he found that his characterizations were inadequate and began to study the how heaviness, as a measure, was comparable to various specific gravities of bodies, or matter, that have the same volume.
Galileo was a well known astronomer and physicist during the time of the Renaissance. He was born on February 15, 1564 in Pisa, and died in Arcetri on January 8, 1642. Galileo attended the University of Pisa where he studied medicine. However, He became more interested in astronomy and physics and decided to make that his profession. Before Galileo, the solar system was a mystery to everyone.
According to Alexander Koyre in The Philosophical Review, Galileo was the first to recognize the importance of mathematics as a tool for understanding the natural world. He was one of the first to use mathematics to explain and predict physical phenomena, and he developed an accurate description of how objects move in two dimensions and how they are affected by acceleration. He also demonstrated the motion of the planets around the sun, and established the law of inertia, which states that a body in motion will remain in motion unless acted upon by an external force. Galileo’s work revolutionized the scientific community by creating the foundation for modern physics and astronomy. His discoveries fundamentally changed our understanding of the universe, and contributed to the development of the scientific method.
This led to him constructing more advanced telescopes and selling them for profit. Using his telescope, he discovered Jupiter’s four largest moons, the rings around Saturn, and the planet Neptune. He also discovered that Earth’s moon has mountains, the Milky Way is made of stars and that Venus has phases similar to Earth’s moon. Venus’s phases were the first piece of empirical evidence to show that the planets orbit the sun. Galileo also established that gravity affects all objects equally, regardless of their weight and that objects are accelerated by gravity at a constant rate so that the distance fallen equals the time squared.
“Isaac Newton was born in 1643 to a poor family in the United Kingdom. Growing up, his mother hoped that he would one day take over the family farm but he decided that farming was not for him. He ventured to study at Trinity College at Cambridge at the age of 19 and fell in love with the writings of natural philosophers. He specifically favored the writings and experiments of the Italian genius Galileo Galilei. Galileo’s ideas about inertia and motion paved the way for Newton’s three laws of motion.”
Galileo saw sunspots, the valleys, craters, and mountains of the moon, the 4 moons of Jupiter, and finally, the phases of Mars and Venus. Galileo also had many stimulating thoughts throughout his lifetime. Galileo believed that the 10 spheres surrounded the Sun, and not the Earth, and Galileo’s discovery of the phases of Mars and Venus had led Galileo to believe in this Copernican school of thought (of Heliocentrism), because the only way that Mars and Venus could have phases, is if they orbited around the Sun. Another phenomenon that Galileo thought of was the principle of inertia, and in this, Galileo had hypothesized that if uniform motion was applied to an object, it would move at an accelerated rather than a uniform force. Throughout Galileo’s lifetime, he said many things, and made many arguments.
Curious with the world and stars around him, he designed an improved telescope which allowed him to view the moons surface, and as far as the rings of Saturn. In the 16th and 17th century, that is quite a feat. Also, Galileo had great contributions to the beginning phases of laws of motion. Having done many experiments of the rate in which objects fell, helping him develop the concept of inertia. While viewing the heavens through his improved telescope, he saw moons orbiting Jupiter and the roughness of our moon.
Then, Galileo came about and he found that two objects fall at the same rate and strike the ground roughly at the same time. But Galileo basically observed objects and described them, he never really came up with how to solve the force or speed at which objects were moving. Both of the Greek philosopher and Italian Astronomer were wrong, or they simply failed to fully understand motion and how to solve it.
Newton made a mathematical formulu of gravity that explained both the motion of a falling apple and the motion of the planets. He showed that the gravitational force between any two objects is similar to the product of their masses and inversely proportional to the square of the distance between them. When applied to the motion of a planet around the sun, this theory explained all three of Kepler's
Galileo Galilei Galileo Galilei was born in Pisa, Italy on February 15,1564 and died in January 8, 1642. Eldest son of Vincenzo Galilei and Giulia Ammannati. Talian natural philosopher, astronomer, and mathematician who made fundamental contributions to the sciences of motion, astronomy, and strength of material and to the development of the scientific method. His formulation of circularinteria, the law of falling bodies, and parabolic trajectories marked the beginning of a fundamental change in the study of motion.
Galileo also may have made the first recorded studies of the planet Neptune, though he didn't think it was a planet. Galileo helped to support Copernicus’ theory. Copernicus theory was that the sun is the center of the universe and the planet revolve around also known as the heliocentric theory. His observations of Venus and the fact that Jupiter had moons that did not orbit Earth, helped support the theory. He ended up becoming a Italian physicist.
