For a long time, when people looked up at night, they always wanted to know more about sky, stars, and the space outside of earth. Human beings never forgets to get more imformation about the things outside of earth. Do you know how human started to know about astronomy and classify them as a completed system. It is because of a person, he uses his life to prove and protect the truth, even his enemy is church, and pope. He is Galileo. 

He is a Italian mathematician, physicist and astronomer. He was born in Pisa, Italy. He was in a decline noble family. His father Vincenzio Galilei is a musician. When Galileo was 17 in 1581, he was studying medicine in the Pisa University, but he was interested in maths and physics. Then he started his way on them. He was poor to keep study in the university, but he studied by himself. He focused the study about Ancient Greek's scientific paper, he wrote thesis Balance in 1586, then he was called "the Archimedes of the time".

He kept focusing about mechanics, then his new thesis about center of gravity brought him a lot of honor, he came back to Pisa University and became the professor. He invented 40x telescpe, and his study gives a strong help about astronomy. From mechanics, physics, he doesn't think that's enough for what he wants to study more about. Then he starts to get in touch and give a system form about astronomy with the help of his invention, astronomical telescope. 

When he starts to know about astronomy, he noticed that another astronomer Copernicus's thoughts are closest to truth. Long time ago, human thinks about space is earth is the center of the space, everything inclued outside of earth goes around it. It got organized by Ancient Greeks, and the one which is the most famous one is Aristotle. The roman catholic church supported geocentric theory, because their viewpoints can protect and keep their theology world and their control power to earthliness. But Copernicus knows the truth is not like that and he proves that earth is not  the center of the earth, only sun is. His thought is called heliocentric theory, and his thoughts start to threaten geocentric theory, which is the roman catholic church supports about. The church and pope were afarid of Copernicus' thoughts, because it's the truth and it may take away all the benefits they have.

But Copernicus still decided to protect his own thoughts, the truth. Finally in the end he got burt, and he died. His soul gets reborn in the fire, the fire with sins. Galileo looked forward and he wasn't afraid of the roman catholic church and pope behind it. He stood up and against geocentric theory, and he supported Copernicus' thought, heliocentric theory.

The vile church's revenge came quickly and strongly. They gave Galileo life imprisonment, and they made him gave up about Copernican. Galileo's late life is really poor, he has nothing left, even his free to think. But I believe he never regreted. He was brave to face all the things that the church tried to persecute about.

Overall, what I learned about Galileo is all about being brave and protect truth is honorable, we need to live honorably that we can not waste our life. After we learned about Galileo, we will understand what under his heart, and the power that helps him to fight against sins until he died. That is courage.
