Tycho Brahe
Tycho Brahe was a Danish astronomer who was famous for studying the stars and losing part of his nose in a fight with Manderup Parsbjerg. In 1572, he spotted a supernova in the sky and studied it. He called it the "new star" (Stella Nova in Latin) and becomes a renowned astronomer. His foster father and uncle died of a pneumonia after saving the King of Denmark from drowning. He died in 1601.

Galileo Galilei:
Galileo Galilei was an Italian Renaissance Man (he had many jobs, a physicist, a mathematician, an astronomer, and a philosopher) who played a key role in the Scientific Revolution. He discovered the "law of falling bodies", a theory that gravity pulls all bodies to the Earth at the same speed, so he dropped a 10-pound weight and a 1-pound weight from the Leaning Tower of Pisa and those two weights fell at the same time. He also concluded that the planets revolve around the sun, but the church did not like this idea. It ordered that the people should not read his books, and placed Galileo under house arrest until his death in 1642.

Isaac Newton:
Perhaps the most recognizable person of these three is Sir Isaac Newton. He was born on Christmas Day 1642 and he is most famous for discovering gravity. Newton told people that he wanted to observe an apple falling from a tree to conclude his theory of gravity and why things stay on the ground. Galileo's "law of falling bodies" is said to inspire Isaac Newton's theory. Descendants of said tree are here today at the Cambridge University Botanic Garden and the Instituto Balseiro library garden. He died in 1727, and was the youngest of the three (Tycho, Galileo, and Newton) in this article. Gravity is slipping and falling on banana peels.
