On 11 November 1572, Tycho observed a very bright star, now named SN 1572. in the first instance Tycho observed that the object showed no daily parallax against the background of the fixed stars. This implied it was at least farther away than the Moon and those planets that do show such parallax. -
Johannes Kepler learns more about the earth
In 1605 he announced The First Law: Planets move in ellipses with the Sun at one focus. Prior to this in 1602, Kepler found from trying to calculate the position of the Earth in its orbit that as it sweeps out an area defined by the Sun and the orbital path of the Earth that: The radius vector describes equal areas in equal times. (The Second Law) On May 15, 1618 he discovered The Third Law: The squares of the periodic times are to each other as the cubes of the mean distances. -
Galileo opening new things in astronomy
Galileo's most valuable scientific contribution was his founding of physics on precise measurements rather than on metaphysical principles and formal logic. More widely influential, however, were The Starry Messenger and the Dialogue, which opened new vistas in astronomy. By December 1609, Galileo had built a telescope of 20 times magnification, with which he discovered mountains and craters on the moon. -

But the most important contribution Descartes made were his philosophical writings; Descartes, who was convinced that science and mathematics could be used to explain everything in nature, was the first to describe the physical universe in terms of matter and motion, seeing the universe a as giant mathematically designed engine -
Sir Isaac Newton's Theory
From a time period from 1660 Newton had came up with the laws of gravity and had confirmed Keplars laws of planetary motion. Newton discovered the law of gravity after and apple fell from and apple tree and hit his head and that go him thinking about gravity. (P.362) -
William Harvey
Harvey disproved the theory of ancient Greek thinker Galen of Pergamum therum that blood was continuously produced and consumed by the body Harvey estimated how much the heart pumps every time it beats and how many times it pumps per minute and that the body was circulating the same blood through the heart.

Aristotle writes the truth on "natural philosophy"
