Galileo

By Aidan Isenstadt

Paragraph one

Galileo Galilei was born in Pisa, Italy, February 15 1564. Although Galileo's father wanted him to be a musician like himself, he decided to dedicate himself to science. Galileo is credited with 6 scientific published works that include;Sidereus Nuncius (Sidereal Messenger), Lettere sulle macchie solari (Letters on sun spots), Lettera a Madama Cristina (Letters to the Grand Duchess

Christina), Il saggiatore (The Assayer), Dialogo (Dialogue on the Two

Chief Systems of the World), and Discorsi (Discourse on the

Two New Sciences).Also, Galileo studied the pendulum immensely in 1602 and discovered that the pendulum's swings will never end. All in all, he influenced modern science by discovering Jupiter's moons, creating the science of motion, and provided a detailed sketch of our moon

Explanation

•Galileo wrote many scientific documents.

•Galileo also made many discoveries

-finding jupiters moons

-Creating the science of motion

-providing a sketch of the moon

Paragraph 2

Four of Jupiter's moons are called the Galilean Moons because he discovered them. At the time he thought they were four small stars orbiting Jupiter. The Galilean moons are Io, Europa, Ganymede, and Callisto. In his journal he wrote "We see no less sensibly that of the satellites of jupiter." At which point he realized that if moons orbited Jupiter than the earth must orbit the sun (heliocentric model). Galileo studied Jupiter's moons for a month and discovered four satellites that appeared to be orbiting Jupiter. Galileo's evidence pointed to the heliocentric model, opposed to the copernican theory. The copernican theory was that earth was the center of all revolutions and that no other objects had satellites. So when Galileo discovered the four moons of Jupiter he provided evidence for the heliocentric model of the solar system.

Explanation

Galileo discovers moons orbiting Jupiter


-Galileo wrote "we see no less sensibly of the satalites of Jupiter


-Galileo studied the satalites for a month and they appeared to orbit Jupiter


-Galileos discoveries helped support the heliocentric model of our universe

Paragraph 3

Galileo's discovery of the science of motion changed modern science forever. Galileo's 1638 book, Dialogues Concerning Two New Sciences, showed that Galileo tested larger and smaller falling bodies, and discovered no difference in rate. According to Galileo's Dialogues Concerning Two New Sciences, "We infer that larger bodies move with the same speed provided they are with the same specific gravity". He proved that bodies of mass fall at the same rate by rolling metal spheres down ramps and finding no differences in speed. After Galileo's study of rate, he went to Padua, Italy, and was intrigued by the pendulum's motion. He continued his research, and discovered the law of uniform accelerated motion. He wrote the first accurate laws of motion. zebu.uoregon.edu states "Galileo laid down the first accurate laws of motion for masses". He also discovered the concept of inertia, velocity, and the idea of force. Galileo's discovery of accurate laws of motion was one of the great achievements of modern science.

Explanation 3

Galileo discovered the science of motion


-Galileo tested smaller and larger bodies of mass falling from the same height and found they fall at the same rate

-he rolled metal spheres down ramps and they rolled at the same speed

-he wrote the first accurate laws of motion

Paragraph 4

Finally, Galileo provided a detailed sketch of the moon as he saw through his telescope. According to The Galileo project (Rice University) "Galileo Noticed dark and light spots that changed as time passed". He realized that if the light was hitting the moon differently in different places then the "spots" wouldn't move, but Galileo noticed the "spots" moving which proved his theory that there were abnormalities on the face of the moon. Galileo's sketch showed abnormalities in the surface, "Which projects in some places the great spots adjacent regions are always brighter as I have noticed in drawing my illustrations." (Siderus Nuncius). In other words he drew elaborate sketches of our moon. The drawings showed that there were abnormalities in the surface. The church at the time had believed that the darker and lighter spots on the moon were just the light hitting the surface differently. Galileo led the way for later astronomers to look up at the sky with an improved tool which influenced modern science.

Explanation

-Galileo noticed dark and light spots that moved around the moon


-Galileo's sketch showed abnormalities in the surface of the moon


-the church at the time belived that the darker and lighter spots was light hitting the moon differently

Conclusion

Galileo influenced modern science by discovering Jupiter's moons, creating the science of motion, and provided a detailed sketch of our moon.
