Nicolas Copernicus
Nicolas Copernicus was a Polish Priest and an astronomer, who was not known for unorthodox thought. He was educated at the University of Kraków in poland and later in Italy. Copernicus published On the Revolutions of the Heavenly Spheres, which challenged the Ptolemaic System and created his own which had all of the planets rotating around the sun in a circle. -

1543 De Revolutionibus Orbium Caelestium (On the Revolution of the Heavenly Orbs)
In 1543 Copernicus published On the Revolutions of the Heavenly Spheres, whcih challenged the Ptolemiac picture. In the book he shared his own ideas that all of the planets moved around the sun in a circle. In his book Copernicus argued that the farther planets were from the sun, the longer they took to revolve around it. -

Galileo Galilei
Galileo was the first person to turn a telescope on the heavens. Galileo saw stars that had never been seen before, mountains on the Moon, spots moving on the sun, and moons orbiting Jupiter.

Johannes Kepler (1571-1630)
Johannes Kepler was and assistant of Brahe's, he discovered that in order for the Sun to be the center the paths of the planets must be elliptical and not circular like Copernicus thought. His book was entitled The New Astronomy, which solved the problem of planetary motion. -
Jan 1, 1572
Crab Nebula
The Crab Nebula is the shattered remnant of a massive star that exploded in supernova explosion. The star was first noted by a Chinese astronomer in the year 1054. The star was rediscovered by Brahe, when he was studing the sky and noticed a spot that he had not seen before. -

Rene Descartes
Rene Descartes was the inventor of the Scientific method, which marked a change in styles of research and new theories and speculation. -
Giordano Bruno burnt
Giordano Burno was a astronomer who expaned the copernican metod and focusd on a sun centered model. In 1600 he was arrested for being against the Catholic Church. -
Three Laws of Planetary Motion
Kepler's laws are:
The orbit of every planet is an ellipse with the Sun at one of the two foci.
A line joining a planet and the Sun sweeps out equal areas during equal intervals of time.
The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit. -
One of the Laws of Planetary Motion
An equal area of the plane is covered in equal time by planet revolving around the Sun. (or the period of revolution around the Sun is proportional to distance from the Sun.) -
1615 Letter to Grand Duchess of Tuscany
The Letter to Grand Duchess of Tuscany , was written in 1615 by Galileo Galilei and was an essay on the relation between the revelations of the Bible and the new discoveries being made in science. -
1620 Novum Organum (New Tools)
In Novum Organum, Bacon details a new system of logic he believes to be superior to the old ways of syllogism. This is now known as the Baconian method. -
Theory of Induction c.f. Karl Popper, David Hume
This theory was one that stated man learns by experience and practice not be lesson and acceptance. -
William Harvey
Harvey opened this text a book fair where it would be dispersed quickly and reported his findings on blood circulations and the cardiovascular system. -
Dialogue on Two World Systems

1633 Galileo banned by the Church
In 1633, Galileo was banned by the Church because of his influence in the Copernican model, which the Church did not like because it did not have everything revolve around the Earth. -
1637 Discourse on Method
Decartes published this text in order to voice his opinions on skepticism and that humans naturally need questioning to further inderstanding. This is still used as an important philosophical text. -
Discourse on Two New Sciences
Discouse on Two New Sciences was Galileo's final book and covered much of his work in physics over the preceding thirty years. -
Theory of Deduction
Theory of Deduction: this system of learning taught that one must only draw logical conclusions and not make up an answer. -

Isaac Newton (1642-1727)
Isaac Newton created modern Physics and was able to prove the laws of gravity and inertia. Newton was also very religious and saw science a representation of the divine power of the creator. -

Jean Picard was an French Astronomer, who did extents research with the distance to Mars. He used parallax to determine the distance to Mars. -
1687 Philosophiae Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy)
This text encompasse three volumes where Newton states his laws of motion and physics. -
Newton's Three Laws of Motion
Newton's Three Laws of Motion
A body moves in a straight line unless impeded. (Inertia).
Every action has equal and opposite reaction.
Every body attracts every other body with a force proportional to the distance between. -
Opticks
This is a book published by Issac Newton which dealed with light and reflection -
Malpighi and Capillaries 1661
Even though Harvey understood the way the blood circulates through the human body, he had never actually seen it himself. It was Malpighi that was the first to observe the blood coursing through the capillaries of a frog
