Document Summary
Galileo: discoveries changed astronomy, supported sun was at the center. (heliocentric solar system, first to observe with a telescope, galileo actually tested/experimented, father of modern science . Scientist originally just talked about problems: dark spots on the sun"s surface that move at a regular speed, proved that the moon was not perfectly smooth, the sun rotates, moons of jupiter, saw the shadows on the moon. Galileo: sunspots, realized they were not stars, they were moons, galilean moons, observed venus goes through a set of phases, saw saturn has rings, milky way has millions of stars. Invented reflecting telescopes: developed the universal law of gravity and 3 laws of motion, describe physical world. 1st law: objects of rest remain in rest and objects at motion remain unless something interferes. 2nd law: force= mass x acceleration, acceleration is rate of change, low mass= high acceleration, high mass= low acceleration.
