Galileo was born in Pisa in Italy on February in 1564 and he was the eldest in his family. He had learnt the education near his father until 11 years and he joined in the college to learn the medical science subject on his fathers wish.

Before Galileo, Copernicus told that the planets are moving around the sun and Galileo proved this with the help of the telescope. Galileo found the spots on the sun, phases of Venus and Jupiter planet. Galileo also invented the compass which is used in the measure various measurements. Galileo also proved that the one pound and 100 pounds object fall on the earth at the same time and he said that the belief that was believed by the people was wrong. The religion heads at that time opposed Galileo and stopped the printing of the Galileo books. They sentenced him to jail in 1623.
