Galileo Galilei

Galileo

Galileo Galilei was an Italian scientist. He was an astronomer, physicist, engineer, philosopher, and a mathematician. Galileo is most well known for his amazing astronomy and his experiment on the Leaning Tower of Pisa.

Galileo was born in Pisa, Italy, on February 15, 1564. He was the eldest child of Vincenzo Galilei, and Giulia Ammannati. Galileo's family belonged to the nobility of Italy, but his family wasn't exceptionally rich. 

Galileo was most famous for his astronomy. At the time, the people thought that all the planets and the sun would revolve around Earth, but Galileo thought differently. He proved this theory incorrect, although he was found to be guilty for heresy,which means to say something against the rules  , by the church. Galileo also made a very effective telescope. While the telescopes at the time magnified 3x, Galileo's magnified the view by 9x. With his telescope, Galileo found the Galilean moons, Jupiter's largest moons.

Galileo also did experiments mass and gravity. It had long been believed that heavy objects would drop faster than light objects, but he was always curious about whether this was true or not. One day, he went up to the top floor of the Leaning Tower of Pisa. He dropped two objects of different weight down at the same time and they hit the ground at the same time. He found that what determines how fast something will drop is gravity and air resistance.

I believe that Galileo was an amazing scientist and his inventions and discoveries were key to our modern world today.
