Ptolemy
Ptolemy was an astronomer who believed that everything in the universe had revolved around the Earth. Even know his theory was proven wrong, it was given the name "Geocentric" meaning "Earth- centered." -
1200
Roger Bacon
Roger Bacon was an English philosopher and he studied mathematics, astronomy, optics, alchemy, and different languages. He was also a monk, but he tuned away from religious beliefs and teachings. He preferred alchemy, which was the backbone of chemistry. His work soon bled into the Scientific Revolution. -
1500
Nicolaus Corpernicus
Nicolaus Corpernicus was a Polish scientist. This theory also ties back to Ptolemy's theory, Corpernicus had soon abandoned Ptolemy's theory for his own called "Heliocentric" meaning "Sun - centered." -
1543
Andreas Vesalius
Vesalius was a Flemish scientist, who studied biology, the practice of medicine, and anatomy. He refused to keep following the descriptions of the human body that were published 1,400 years ago, this pushed him to start studying anatomy of the human body. His eventually published 7 volumes of "On the Fabric of the Human Body" in 1543. This better helped people understand about the human body. -
William Harvey
Harvey was an English physician. He, like Vesalius studied anatomy, he used multiple experiments to study how blood circulated throughout the body. He showed how blood moved through veins and arteries. Harvey also studied the human heart. -
Johannes Kepler
Johannes Kepler was a German astronomer and mathematician. To help prove Copernicus's theory he used a combination of math and observation. Some of the original facts that Copernicus stated were wrong, but, in the end Kepler proved the Heliocentric theory to be correct. He eventually published his planetary laws in 1609 -
Francis Bacon
Bacon was an English scientist and philosopher. He believed that scientific theories should be proven using multiple experiments. He also believed that facts should be prove through physical experiments, not by thinking and reasoning. To assist this new knowledge he published "Novum Organum" in 1620. -
Galileo Galilei
Galilei was an Italian scientist, natural philosopher, astronomer, and mathematician. he made his own telescope so that he could study the sky and stars, since he could see the moon up close he drew pictures and wrote about it. He eventually published his findings in 1632. Galilei also discovered that all things fall at the same rate if there is no air resistance. -
René Descartes
Descartes was a French mathematician, scientist, and philosopher. He stated that if you were to make a theory, it would have to be proven by preexisting facts. This helped people make theories based on logical thinking. -
Robert Boyle
Boyle was an English-Irish scientist. He helped modernize science and chemistry. One of the ways he did this was showing how temperature and pressure effect different gasses. This helped more people study gasses and different elements. -
Antoni van Leewenhoek
Leewenhoek was a Dutch scientist. Even know the microscope was invented in the late 1500's he used his home made one to discover bacteria. He called them 'animalcules' meaning smaller animals. The discovery of bacteria was useful to the scientific revolution was important because people could now study bacteria finding out how it would effect the human body. -
Gottfried Liebnitz
Liebnitz was a German philosopher, mathematician, and political adviser. Through his studies in mathematics, he eventually discovered a new branch of mathematics called calculus and laid out the basics of this new form. This helped people conduct more complicated experiments that required more complicated forms of math. -
Isaac Newton
Newton was an English physicist and mathematician. He a published a book declaring that all the planets in our solar system did indeed revolve around the sun. after numerous experiments, he came up the law of universal gravitation witch says that all bodies attract each other. He also came up with the laws of motion. -
Antoine Lavoisier
Lavoisier was a French chemist. He proved that fire was not actually an element, by rapidly combining oxygen with substance. He also named the element Oxygen. This help scientists better understand chemistry -
Joseph Priestley
Priestley was an English chemist, clergyman, political theorist, and physical scientist. Through his studies, he discovered ten new gasses, on of the most important and famous ones was the element, oxygen. This would help others understand more about chemistry and the different elements.
