Ptolemy
He belived that the universe was geocentric, or the Earth was the center of the universe. This challeneged popular beliefs and was the first to puclicize them. -

Galen
Galen wrote about the anatomy of the human body. He was a Roman physician and philosopher. -
1500
Nicholas Copernicus
He belived the sun was the center of the universe, or heliocentric. His theory were ignored because if the peoples older beliefs about the universe being geocentric. This challenged Ptolemy's theroy and changed many peoples way of thinking. -
1543
Andreas Vesalius
Andreas was a Flemish scientist that studied the human body. He used the words of Leonardo da Vinci, " I advise you not to trouble with words unless speaking to blind men." Working on his own he studied and experimented with the human body. Publishing a seven-volume book called "On The Fabric of The Human Body." The book helped its readers learn more about the complexity of the body. -
1578
William Harvey
William Harvey studied the movement of blood through the body and how the heart veins and arteries work together to pump blood throughout the body. -
René Descartes
René Belived that all sciences were connected and that they should be studied together. His studies ranged from geometry, algebra, astronomy, the scientific method and even physical sciences. René created a mathmatican description to show how light reflects of of a flat surface, this led to the law of refraction. Much of his work challenged the churches beliefs and he was forced to live his life in Sweeden, a protestant kingdom. -
Hans Lippershey
A German-Dutch lens maker created the first telescope. -
Johannes Kepler
Kepler uses mathmatics, models and observations. Though some of Copernicu´s theories were wrong Kelper eventually proved the heliocentric theory as correct. -
Francis Bacon
Francis lived around the same time as Descartes. He believed that scientific theories could be developed through observation. He said that no assumption could be trusted unless it could be proven by repeatable experiments. In 1620, Francis published 'Noveum Organum'. This book outlined this new system of knowledge that was created. -
Galileo Galilei
Galileo built his own telescope and mapped the stars. Observing and sketching the moons orbiting other planets and the rings around saturn. Many people rejected his findings stating that it was of the devil because it contradiced the bible, and many still belived Ptolemy. -
Robert Boyle
Boyle helped pioneer the modern science of chemistry. These studies helped people study the composition of matter and how it changes. In 1662, Boyle showed that temperature and pressure affected the space that a gas occupies. -
Issac Newton
Biulding on the gaps in Copernicus, Kepler and Galileo. Their work Stating that the planets orbited around the sun but could not explain why they did so. Newton found that the force that caused objects to fall to the ground was the same force that holds the planets in place. Proposing the law of universal gravitation. Proving the heliocentric theory and the work of Kepler and Galileo. -
Antoine Lavoisier
Before Lavoisier discovered that fire was found when a substance rabidly combined with oxygen, people believed that fire was an element. He also showed that steam mixes with the air and becomes invisible. By doing the experiments to find these findings, Lavoisier proved that matter can change form, but that it can be neither created nor destroyed. This idea is now known as the law of conservation of matter. Making it one of the most important principles in the study of chemistry.
