How Did Galileo Improved The Thermoscope

Although, Galileo did not invent the telescope, he is thought as the inventor of the telescope. Hans Lippershey was the person who invented the telescope in 1608. Galileo learned about the spyglass in 1609. He thought that learning about spyglass was so exciting and interesting. His interest of the spyglass led him to the discovery of improving the telescope. In order to discover deeper, Galileo began to experiment with making the telescope and polished the lenses of his own telescope to increase the range about eight to nine times further. Due to Galileo’s improvement of his telescope’s range, he was the first person to discover sunspots, to see the moon’s craters, and to keep on track of the phases of

Galileo has been credited with the confirmation of the phases of Venus, the discovery of the four largest satellites of Jupiter, and the observation and analysis of sunspots. He also worked in mathematics and with technology, helping to improve the military compass. Galileo was a renaissance man.

Among these people were Copernicus who believed the sun was at the center of the world and the earth, stars and planets revolved around it. Danish astronomer Brahe helped contribute to this idea by contributing a large mass of data about the universe that he was able to discover. His student Kepler kept his ideas going, as he formulated many laws of planetary motion. He said the orbits around the sun were elliptical, planets don’t move in a uniform speed and the time a planet completes its orbit is related to its distance from the sun. Meanwhile, Florentine Galileo decided to use experiments to find out what happened and not what should happen, and discovered that a uniform force makes a uniform acceleration as well as inertia laws, that an object will be in motion forever unless stopped by another force.

Document 3 shows how Galileo’s observations of the moon and laws of motion supported Copernicus’ heliocentric model. He discovered that the moon has craters, and is not a perfect sphere like Aristotle said. This was able to prove that Copernicus was correct. However, the Church disagreed and disliked his work. It was rejected by the Church and he was forced to recant or face execution.

During the time of Galileo, the church was very strict with physicists who believed in the Copernican model. This is exactly the position that Galileo found himself in. In 1600 Galileo began making his own telescope. He became the first person to point one at the night sky. What staggered him the most by doing this was the sheer volume of stars that were not visible with the naked eye. Galileo used his telescope to make many discoveries; one of these is the discovery of Jupiter’s four moons. He even plotted and tracked there rotations around Jupiter. The main thing however, was that Jupiter even had moons, this was proof that the geocentric model was incorrect and that this discovery was in favour of the Copernican model.

Galileo(1564-1642) Made the telescope better and he used the telescope to observe planets, and he proves kepler’s theory, saw the imperfection of planets, and saw a storm on a planet also saw craters.

Scientifically, Galileo will be remembered for invention of the telescope, which allowed astronomers, sailors and other view the heavens and seas, which fed their own theories. He used his own invention to discover the four moons of Jupiter, the mountains and craters of the moon, and sunspots. His work on falling objects led to gravitational studies and mathematical theorems which are on a basic level, physics. Experimentation was used as a means to prove the laws of science along with the mathematical theories. Math, according to Galileo, was the only infallible form of logic. If a mathematical law could be formed from an event, then it was a logical, rational event. His breaking from the Catholic Church, voicing his findings and staying with his convictions broke the traditional way of thinking that the Church was the end all and be all of all things. In the end, he was proven right for most of his beliefs and vindicated for his suppression.

During the 1600’s there was an outstanding advancement, the Scientific Revolution. Everyone had open up to the idea of science and was going away from the church. Scientist were finding out that what they had thought before was wrong, by proving that it could not be possible. People were trying to better understand the universe and how it worked. Some scientist were more curious than others, which lead to make discovery and advancement of further progress science. Johannes Kepler discovered motion of the planets, changed the way people consider about the universe.

Galileo Galilei was also a supporter of the Copernican Theory. Galileo believed the earth, and other planets, rotated on its axis around the unmoving sun. He used his new invention of the telescope to prove Copernicus’ theory. With the telescope, Galileo found sunspots on the earth’s moon, which gave proof to him that the heavens were not perfect and changeless but were more like the changeable earth. iv He also discovered Jupiter and the four moons that revolved around it. He only discovered one moon revolving around the earth. Galileo therefore stated if Jupiter were to revolve around the earth, then the earth would have to have at least four moons, and it doesn’t. v The Church objected Galileo’s theory because the Bible said the sun moved through the sky. Being totally rejected by the church, Galileo was forced to take back what he had written and was also prevented from any further teachings of his theory. Galileo was condemned by the Catholic Church for his ideas. The Church succeeded in silencing Galileo but couldn’t stop the advancements in science.

The use of the telescope led him to discover new characteristics of space and the solar system. He discovered Jupiter’s four largest moons and the rings of Saturn. He also discovered that the Milky Way galaxy is comprised of stars. The observation of mountains on the moon was made by Galileo as well. He also made numerous discoveries within these discoveries.

When Kepler first began his work on the orbit of Mars he was under the assumption, as many scientists were, that the planetary orbits were circular, and that the Sun was at the center of the orbits. This type of system is called a heliocentric system. Also at this time only six planets were known. When Kepler obtained Brahe's data he discovered that the orbits were not perfect circles, but instead were ellipses that were only slightly flattened. The reason nobody else realized this was because the orbits were so slightly elliptical that extensive investigation and data would be needed to show this. It also turned out that the reason the orbit of Mars was very difficult to understand was because its orbit was more eccentric than the other planets that Kepler and Brahe had data about. To understand a lot of Kepler's work you must first

hide his lack of proof by focusing on only what he knew. His actions on the

Galileo’s observational discoveries in astronomy allowed for the basis to begin discrediting the old ideas in favor of a new understanding of the universe. The longstanding way of thought in astronomy favored a spherically rotating universe around the Earth with unchanging and perfectly symmetrical constellations and planets. The contemporaries of Galileo believed, for example, that the moon had the face of a shiny, polished sphere, whereas Galileo showed that the surface of the moon to be imperfect with rough mountainous areas along with deep valleys (or “seas” as he called them) marked with dark sports (Frova 162). This surface very much paralleled the rough surface of the Earth (meaning that Earth’s surface was not unique). Also with his improved telescope, Galileo was capable of viewing the stars with much more clarity. Galileo discovered newly formed stars and star clusters, which challenged the Aristotelian philosophy of an ageless universe. Additionally, Galileo observed four of Jupiter’s largest moons orbiting around the planet (Frova 179). His observations of Jupiter’s satellites did not agree with the idea that all heavenly bodies must rotate around a central Earth. Finally, and arguably most important, Galileo showed Venus’s phases and

Galileo Galilei built a telescope in 1609, and he studied the night sky, observing the earthlike features of the Moon, moons orbiting Jupiter, and sun spots. He published his work, which later earned him a trial by the church and a house arrest for life. “According to a story that began to circulate shortly afterward, as he left the court for house arrest he stamped his foot and muttered defiantly, looking down at the earth: Still, it moves” (page 530, Chapter 16). Francis Bacon and René Descartes established standards of practice and scientific evidence, and they were true believers in human thinking. Physician, William Harvey contributed to science by observing dissected living animals and experimented on himself that the blood circulates in our bodies through veins, heart, and arteries. Inventor and experimenter Robert Hooke introduced microscope into the laboratory and studied the structure of plants on the cellular level. Isaac Newton gave us laws of motion, universal gravity, the reflecting telescope, optic theories,

In 1609, Galileo Galilei, using “spyglass” which allowed one to see things closer than they appeared, made an early version of the telescope. With it, he observed the skies in a way no one had before. He discovered the moon isn’t perfectly globular, it has craters, the Sun has sunspots, Venus orbits the Sun (contrary to widespread belief in his time), and then he observed four “stars” around Jupiter (“Our Solar System”).
