scientist
contribution
developed the heliocentric theory, which placed the sun at the center of the solar system
used the telescope to observe moons and planets, supporting heliocentric theory
defined the three laws of motion that govern the planetary bodies, as well as objects on earth
explored fluid pressure and the relationship between pressure and depth
studied the properties of gas, developing a law which states that the volume of a gas varies with the pressure exerted on it
