A GENIUS!

 Sir Isaac Newton  Galileo Galilei  Tyco Brahe  William Harvey

 Sir Isaac Newtown was born in 1642 and died in 1727  He was born on Christmas day  He is still considered one of the greatest scientists of all time

 It is know that Sir Isaac Newton attended the college Cambridge.  He graduated with a B.A. degree  There is a manuscript of his, dated May 28, 1665, which is the earliest documentary proof of his invention of fluxions.

 His 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.

 Isaac 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’s laws are helpful now in classes such as math and chemistry. Using these laws help us figure out equations.

 Galileo was born on February 15, 1564 and died January 8, 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.”

 Galileo 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.

 Galileo 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,”.

 Galileo 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.

 We still the the telescope that he designed.  He was right about the moon and its mountains.

 Tycho Brahe, born Tyge Ottesen Brahe (14 December 1546 – 24 October 1601)  Brahe was of Danish nationality  Tycho Brahe was well known for his work in astronomy

 Brahe was awarded an estate on the island of Hven, where he built the Uraniborg which was an early research institute  In 1597 he became the official imperial astronomer  Brahe’s discoveries were used by his assistant Johannes Kepler to create the laws of planetary motion

 Tyco Brahe’s theories and findings are still considered to be accurate today

 William was born at his home on April , he died on June 3 rd 1657  He went to school at The King’s School in Canterbury  William was of English nationality

 He was known for his work in the field of medicine and physiology  His most important discovery in systematic circulation  in 1628 published his work Exercitatio Anatomica de Motu Cordis et Sanginuis in Animalibus

 Williams parents were Thomas Harvey and Joane Halke  Elizabeth C. Browne was his wife  Elizabeth was the daughter of Lancelot Browne he was a London physician  William and Elizabeth didn’t have any children

 William Harvey’s idea that the heart pumped the blood through the body is still true today  He proposed that blood flowed through the heart in two separate closed loops
