他是谁？
He was born in Italy.
His father was a famous musician and music theorist.
He received his formal education at a monastery(修道院) when his family moved to Florence.
He attended the University of Pisa(比萨大学) in 1583 and immediately was interested in many subjects, such as physics and mathematics.
He really wanted to be a university professor at first, but after earning his degree, he changed his mind due to economic hardship.
He never stopped to study mathematics and took a minor teaching position to support himself.
As he studied objects in motion for so long, he discovered some significant scientific principles, which earned him some fame.
He met a Venetian woman, who bore him three children, and never hold a formal wedding ceremony for the woman, probably as a result of financial difficulties or fearing that his illegitimate children could tarnish his reputation.
with a simple telescope made by an eyeglass maker, he constructed his own telescope and used it to explore the vast universe, proving some planets rotated around the sun, which disproved that the Earth was the center of the universe.
He developed the universal law of acceleration which had a long-lasting implication for the development of physics.
He said: “All truths are easy to understand once they are discovered; the point is to discover them.”
His support for the sun-center solar system posed a severe challenge to the established order of the Catholic Church(天主教会). As the Church considered him a great threat in his time, he was convicted of heresy and suffered house arrest.
