Galileo
Galileo's Early Life
Galileo Galilei was an Italian mathematician, astronomer, physicist, and philosopher. He was born in Pisa, Italy on February 15, 1564. He was the first of six children of Vincenzo Galilei, a famous composer, and music theorist, Giulia Ammannat. Because of his contributions, he has been called "the father of observational astronomy", "the father of modern physics", "the father of science", and "the father of modern science". Early in life he wanted to join the Church Order, however his parents had different ambitions for their son. They wanted Galileo to become a medical doctor. While pursuing his university studies, Galileo realized he had a passion for mathematics and instead became a professor of mathematics at the Universities of Padua and Pisa.
The Pendulum
In 1581, Galileo began studying at the University of Pisa, where his father hoped he would study medicine. While at the University of Pisa, Galileo began his study of the pendulum. According to legend, he watched a suspended lamp swing back and forth in the cathedral of Pisa. It was not until 1602 that Galileo made his most notable discovery about the pendulum the period, which the time in which a pendulum swings back and forth, does not depend on the arc of the swing, the isochronism. Eventually, this discovery would lead to Galileo's further study of time intervals and the development of his idea for a pendulum clock. Tower of Pisa
As a professor, Galileo argued against traditional views of astronomy. At that point in history, Aristotle’s theories were thought to be the fundamental laws in physics. Aristotle’s belief that objects with a greater density fall faster than those that was lighter in weight. In 1589, he was disproved by Galileo when he stood at the top of the Leaning Tower of Pisa and discovered that the reason for one object falling faster than the other had to do with the friction each encounters while moving through the air- two objects of different weight actually

    He was one of the most important mathematicians since he did something that was revolutionary for his time he experimented. He experimented so he could prove a point to his teacher, Gioseffo Zarlino that there were non-Pythagorean mathematical relationships in the musical scale. Galiliei’s experimenting was particularly important since his son was Galileo Galiliaei and witnessed all the experiments that his father performed which had a deep impact on the younger Galilei. Galileo Galilei became famous for his attention to the study of motion. Galileo realized he could study the free fall of objects with a ball and an inclined plane. This would allow the motion of the ball to be slowed enough to be observed and measured, rather than a quick free fall. He kept repeating this experiment with steeper inclinations until the ball rolled too fast for him too measure. He was able to use his measurements and observations to explain the motion of free fall. When he rolled the ball over stiff lute strings tied across a tilted board it would make a clicking sound. His musician's ear was able to detect the timing of the ball over the strings as it rolled over them. He discovered that a “falling object doesn’t just drop, but drops faster and faster and faster and faster over time.” This is where he concluded that an object's speed increases over time as it falls downward. He was the first to develop the formula s = At2, which is used to calculate the free fall of any object toward earth. Galileo was not only famous for his study of motion though. Galileo was also known for his study on atoms. Galileo believed that atoms were the smallest quanta of matter and that there are an infinite number of atoms separated by an infinite number of voids. Galileo is best known for his telescopes though. At the time, people were very dismissive and critical of his telescopes though. It was necessary to calibrate his telescopes…

    Theory: During the early part of the seventeenth century, Galileo experimentally examined the concept of acceleration. One of his goals was to measure the acceleration due to gravity, or the acceleration of freely falling objects. Unfortunately, his timing devices were not precise enough to measure the free fall time directly. He decided to “dilute” gravity by using fluids, inclined planes, and pendulums.…

    Galileo Galilei (1564-1642) was a believer of Copernicus's heliocentric theory. His discovery of the telescope (1609) allowed him to confirm the theory and his own beliefs. Galileo was first criticized by Friar Lorini. The Friar said that Copernicus's theory violated the scripture. Galileo responded with the Letter to Castelli, hoping it will give back some hope and trust in science. However, it did the opposite, and Lorini, sent a copy of the letter to the Inquisition (1615). On February 1616, Galileo was warned by Cardinal Bellarmine to keep quiet of his ideas or else stronger measures would be taken.…

    -According to Aristotle, larger, heavier objects were supposed to fall to the ground faster than smaller, lighter objects. Galileo performed a number of experiments to Aristotle’s pronouncements, that two objects of different weight dropped from the same height fall down at exactly the same rate.…

    Ever wonder what it would be like to invent something that would be used for hundreds of years to come? That’s what Galileo Galilei did. Galileo Galilei belongs in the house 8-1 Genius Hall of Fame. Born in 1564 in Florence, Italy, Galileo was the oldest of six children. In 1583, he attended the University of Pisa to study medicine but became fascinated with many other subjects, particularly mathematics and physics. He performed studies and tests on falling objects and then wrote a manuscript about the results that he got. Galileo Galilei achieved lots of greatness throughout his time, including inventing the telescope, and believing in himself and his intelligence when no one else did.…

    His famous nickname is “The Father of Modern Science” because of his pioneering observations that made the foundation for modern physics and astronomy. Galileo as a young child earned a proper education in Florence at Camaldolese monastery, Vallombrosa. He then entered the University of Pisa to study medicine but he soon gained interest in mathematics and physics. As a professor in mathematics he made pioneering observations but Galileo was accused twice of heresy by the catholic church. Soon after accused Galileo died January 8, 1642.…

    Revered as the father of modern science by Albert Einstein and identified as being responsible for the birth of modern science by Stephen Hawking, Galileo Galilei played a crucial role in the scientific revolution during the Renaissance period. He defended the astronomical model of Heliocentricism, asserting the Earth and planets revolved the Sun, which was at the center of the Solar System, by supporting Copernicanism. Copernicanism, the advocacy of the heliocentric model of the heavens, which caused much controversy, as many educational authorities were unconvinced or directly oppositional to this belief. Galileo’s mathematical-experimental model not only brought forth theories which allowed Galileo to establish theories which would eventually…

    He was motivated by Copernicus's idea of the sun being the center of the universe which many astronomy acumens didn't agree with. Through his telescope, Galileo observed that planets existed on their own right. He was also able to observe the moon which he said was formed by Moon Mountains and craters. Although Galileo did not come into full agreement with Copernicus's initial idea of the sun being at the center of the universe, at least he agreed that there are some bodies in the universe which revolve around the sun (Dreyer, 1906). This means that Copernicus' idea was not far from the truth as confirmed by Galilei…

    Documents later showed up saying that Galileo had suffered neither imprisonment nor torture. The sentence was decreed and he was never held in prison. When he moved back to Florence, he made a request to be allowed to go to a church to attend mass, he was never excommunicated by the church for his believes in science. His remains were buried at the Church entrance when he died. In 1820, the censorship of Copernicanism was withdrawn by the Holy Office, taken on the discoveries made by two Italian astronomers.…

    Galileo was a very smart man. He created and discovered many amazing things, not all of which were accepted by the beliefs of the Roman Catholic Church. He created a telescope that magnified up to 20 times and began studying space in 1609, (“Galileo”). The telescope allowed him to see many things not visible to the human eye, such as the texture of the moon and Jupiter's four moons. Through the study of his findings Galileo discovered that Venus and Mercury revolve around the sun, and that confirmed his belief that the Sun was the center of the Universe.…

    Galileo would come to invent a thermoscope, which was the predecessor to the thermometer. He also published The Little Balance, which is what brought him to the attention of the scholarly world. Galileo furthered mankind's understanding of astronomy, applied science, as well as making significant improvements to the telescope. He pointed his telescope toward the night sky and discovered 4 moons around Jupiter that are now called the Galilean Moons. He would also use his understanding of ocean tides to make an argument for the fact that the earth moves around the sun, not the opposite, which was what was commonly accepted. The Catholic Church ordered that publishing's of Galileo could not contain references to ocean tides. Galileo was a large supporter of heliocentrism, which caused large amounts of controversy in the Catholic Church because the belief at the time was that the earth was the center of the universe. Galileo went to Rome to defend the scientific position on the issue, but "In 1616, an Inquisitional commission unanimously declared heliocentrism to be "foolish and absurd in philosophy, and formally heretical since it explicitly contradicts in many places the sense of Holy Scripture."(Wiki). As a result of Galileo's trial in 1633, he was ordered to spend…

    While Kepler was creating a new model of the universe Galileo Galilei was tearing apart the out dated Aristotelian system. Conceiving the theory of inertia, disproving the concept that all planets orbited the Earth (essentially providing the proof Aristarchus’s theory lacked) disproving the Catholic church’s geocentric model that had become so fundamental to its dogma, and lastly left a major concept of physics unexplained, to an influential scientist, that was born the year Galileo died.…

    He applied mathematics to his experiments and also used a telescope to make astronomical observations. He discovered mountains on the moon, spots on the sun, and also the four moons of Jupiter; observations that contradicted traditional beliefs that the heavens were perfect. {EXT.} In a letter to Galileo, an Italian monk named Giovanni Campioli tells Galileo, “remove the possibility of malignant rumors by repeatedly showing your willingness to defer to the authority of those who have jurisdiction over the human intellect in matters of the interpretation of Scriptures.” (Doc. 6) This document may be biased because Campioli was a monk, a religious figure, and only considered the universe a religious subject and that, therefore, he thought would make him a more reliable source than Galileo. He wrote this letter perhaps to try and withhold his authority over religious persons and suppress Galileo by insinuating it was in everyone’s best interest. [POV] Galileo was eventually brought before the Italian Inquisition for his theories. The traditional religious beliefs obviously affected his work in a similar way as Copernicus as he had to be careful who he talked to for fear of being found out by the church. Both scientists were limited in what they could do because of the fact that they were contradicting what the church…

    After that he was appointed philosopher and mathematician to the Grand Duke of Tuscany. During the whole of this period, and to the close of his life, his investigation of Nature, in all his fields, was never stopped. Following up his experiments at Pisa with others upon inclined planes, Galileo established the laws of falling bodies as they are still formulated. He likewise demonstrated the laws of projectiles, and largely anticipated the laws of motion as finally established by Newton.…

    He pioneered the foundation for modern astronomy and physics through his intricate and elaborate observations. Galileo was born on February 15, 1564 in Italy. He started the University of Pisa with the interest of going to medical school. Galileo was very intelligent with immense amounts of talent. He had many interests in mathematics and physics when attending the University. This is where Galileo was first open to the worldviews of Aristotle and the scientific ideas that were approved of by the Roman Catholic Church. Like majority of the intellectuals of the time, Galileo accepted the predestined ideas and was on his way to becoming a university professor, but due to the lack of available funds, Galileo had to drop out of school. Galileo kept on continuing his studies and this led him to discover many innovative findings. He developed the law of acceleration, advanced his findings on falling objects and motion, and supported Copernicus’ heliocentric theory. This went against the views of Aristotle, therefore it also went against the Catholic Church. Later Galileo found interest in telescopes and decided to create one of his own. He discovered that the moon was not a flat surface, but indeed it had craters and mountains. He also observed that Venus had phases similar to the moon’s and this resulted in findings that supported the idea of the sun being the…
