Sir Isaac NewtonGalileo GalileiTyco Brahe William HarveyTYCHO BRAHEGrowing upIt is know that Sir Isaac Newton attended the college Cambridge. He graduated with a B.A. degreeThere is a manuscript of his, dated May 28, 1665, which is the earliest documentary proof of his invention of fluxions.Newtons workHis Principia Mathematica (1687) includes Newton's Law of Gravity, an incredibly ground-breaking study. Newton's work destroyed the old notion of an Earth-centered universe.

Fun FactsIsaac Newton invented integral calculus. Isaac Newton made a huge impact on theoretical astronomy. An 18th century poem written by Alexander Pope about Sir Isaac Newton states it best:Nature and Nature's laws lay hid in night:God said, Let Newton be! and all was light.

Newton and TodayNewtons laws are helpful now in classes such as math and chemistry. Using these laws help us figure out equations. http://www.blupete.com/Literature/Biographies/Science/Newton.htm

galileoGalileo was born on February 15, 1564 and died January 8, 1642. he was an Italian scientist.Galileo was an astronomer and he made improvements to the telescope.He is called The Father of Modern Observational Astronomy.

Galilean moonsGalileo discovered the phases of venus, which are different variations of lighting seen on the planets surface.Galileo discovered the four largest moons of Jupiter. They named them the Galilean Moons.

discoveriesGalileo was one of the first scientists to discover sun spots.Galileo was the first person to report seeing craters and mountains on the moon.Galileo tried to measure the size of the mountains and that is how he came to the thought that the moon was "rough and uneven, and just like the surface of the Earth itself, .

More discoveriesGalileo tried to figure out how the tide worked.Galileo thought the tides were caused by the sloshing back and forth of water in the oceans as a point on the Earth's surface speeding up and slowing down because of the Earth's rotation on its axis and revolution around the Sun.If his therory was correct there would be only one high tide a day, and there is two.

Galileo and todayWe still the the telescope that he designed.He was right about the moon and its mountains.
