Galileo Galilei, Astronomer/Mathematician

Galileo was responsible for the creation of modern science becoming a discipline and its concepts and method a whole philosophical system. Galileo’s contributions involved using a telescope to examine space, inventing the microscope, disproving Aristotles laws, inventing the law of the pendulum, advocating the relativity of motion, and creating a mathematical physics. However one of his most important contributions was the fact that he conducted experiments, thus making him the first experimental scientist. Testing ideas with experiments was not a conventional approach in Galileo’s years therefore he revolutionized the way which science was conducted. Some of Galileo’s most important contributions to science include building a telescope of his own from scratch without ever seeing one in 1609. The observations that Galileo made through his telescope gave evidence that Earth is not the center of all things and that the planets orbited the Sun. Among his findings were the moons of Jupiter, the fact that the Moon’s surface was rough and covered in mountains and craters, the complete cycle of phases of Venus, and sunspots. Galileo observed the changing appearance of sunspots and concluded that the Sun rotates once per month around an axis that is perpendicular to the ecliptic plane. These observations supported the Copernican model but rejected the philosophy of Aristotle.

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.

Galileo was first to have the use of a telescope to observe celestial bodies, which helped him greatly in making new discoveries. He was able to not only study the motion of other planets, but was able to observe the satellites orbiting those planets. Galileo also discovered an enormous amount of stars by observing the Milky Way giving way to theorizing that there is more to our universe then what was previously thought. Galileo later found himself in trouble with the Catholic Church for publicly announcing his findings, which went against the Church’s held beliefs of the Earth’s place in our universe. Sadly, Galileo had to essentially denounce his findings and was forced to keep his discoveries private for the rest of his days.

During one of his nightly star gazing rituals, he discovered what he thought to be a new comet. He returned four days later to find the comet to have moved, thus increasing his certainty that it was. He shared his discovery with others, who despite having a hard time confirming his discoveries at first,

Galileo Galilei, the most renowned scientist of the Renaissance period, or the “father of modern science” was known as a jack-of-all-trades: he was an astronomer, physicist, engineer, philosopher, and mathematician just to name a few. But perhaps what he is most known for is spurring the scientific revolution in the late seventeenth century. Galileo challenged what was then considered common knowledge for almost 30 years: for example, the idea of a heliocentric universe. The most controversial of these ideas was embracing the theories of Nicholas Copernicus. Not only did he embrace Copernicus’ ideas, but expanded and substantiated them. The consequences of these actions were multiple trials with the Church regarding his work and later

“Perhaps most important for the science of astronomy is that the discovery of Uranus began the search for other undiscovered planets in our solar system. It was the beginning of a second phase in the discovery of planets, during which Neptune and Pluto were discovered.”

Galileo Galilei was an astronomer, physicist, engineer and mathematician during the renaissance period in Italy. He was born in Italy, Pisa in 1564, and died in 1642 at age 77. Galileo was influential in supporting the Copernican Theory, which suggested that the earth revolved around the sun, and that the earth was not in fact the centre of the universe. He also developed the telescope, and discovered moons orbiting Jupiter, which are now name after him in his honour, the Galilean moons.

Galileo Galilei was an extremely important scientific figure. Known as the father of modern science, Galileo's’ discoveries and advancements helped build the foundation of theorems and technology still used today. From proving the Copernican theory to building his own telescope, he made a huge impact that is definitely worth learning about and noting.

first person to study stars in the universe According to him, the Sun, the Moon, the planets, and the stars travel in separate spheres. When the spheres touch each other, a 'music of the spheres' can be heard proved that the Earth is spherical.

Galileo Galilei was born in 1564 in Florence Italy. Although his family was poor they were noble. His parents recognized and understood his intelligence and made sacrifices for his education. Galilei was an astronomer (a scientist who studies stars, planets, moons, comets and galaxies.) He developed a telescope and made many important discoveries in astronomy. Galilei was important to the renaissance because of his agreement “the sun is the center of the universe, not the earth and that all planets revolve around the sun” which had earlier been stated by Copernicus. He was sentenced to life in prison by the inquisition for his support for the Copernican theory that the sun was the center of the solar system. He died on January 8, 1642.

His first observations were of the moon- noting a heavily cratered surface that contradicted the previous belief held by Aristotle and taught by the Church- that heavenly bodies possessed a smooth and ‘perfect’ surface.

William Herschel was a musician who also dabbled in astronomy. He quickly got sick of trying to study the heavens with the tiny telescopes available at the time, and decided to build his own. It was a great success and he was able to see much farther than previously, so he built more. One night while studying the sky he discovered what he thought was a comet because its position changed from night to night. He notified astronomers in England and France of his discovery, and they were puzzled. One suggested that it might be a planet, so they investigated it further by tracking and calculating its orbit. This confirmed that it was a planet.

Although many remember Galileo as an astronomer, his chief contributions to the world of knowledge were in the dynamic and mechanical fields of science. The first of his many

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 was one of the most famous Italian scantest in the world. He was born on 15 of February 1564. He was interested in physics, mathematics and astronomy. He wrote a lot of books about these subjects which has impact in many aspects on human lives. This essay will tell about Galileo Galilei life, then about what did he invent, after that I will tell about his theory.
