Claudius Ptolemy
Ptolemy created a theory, where the Earth was the center of the solar system, called the geocentric theory. He made this in 100s a.d. People believed this theory for more than 1400 years until Copernicus created the heliocentric theory. This is important because it showed that early science was flawed and it was a step to improve everyone's knowledge. -
Period: 100 to
Scientific Revolution Timeline

1532
Nicolaus Copernicus
Copernicus developed the heliocentric theory. This meant that the sun was the center of the universe. It states:
1. The Earth is not the center of the universe
2. The sun is in one spot and all objects go around the sun
3. The Earth turns on it's axis and orbits around the sun
4. The stars are stuck in one spot
This changed how people thought, before people thought that Earth was the center. They now realized that the sun was now. This is important because it changed how people thought. -
1543
Andreas Vesalius
Vesalius created a book that fully illustrated the anatomy of the human body. This abolished many misconceptions that people had about a human body. Before this book many people thought that women had 1 more rib than men. This book proved that they had an equal amount. This led people to discover more things about the human body, because this book was the resource that most people would use. -
1579
François Viète
Viète helped create the theory of equations and trigonometry. He proved that hard equations could be solved using math. He solved a cypher that was more than 500 characters long. The person that made this cypher thought it was black magic, but since Viète used math he changed that person's idea. Trigonometry helped explain many things that happen with physics, engineering and chemistry. -
Johannes Kepler
Kepler used models and math to further prove the heliocentric theory. This helped change people's thoughts on what the center of the solar system was. He was one of the first people that had evidence to support the heliocentric theory. This is important because it showed that math and models can explain things. This caused people to adopt the ideas easier. -
Galileo Galilei
In 1609 created his first telescope. He did this so he could further prove the heliocentric theory. While noticed many things that no one had noticed before; one is that he noticed that Saturn had rings around it. The telescope held reinforce the ideas that Copernicus made. He observed that the sun was the center of the universe. This is important because it was instrument that allowed us to study space. The telescope helped people create ways to study space. -
Francis Bacon
Bacon stated that scientific theories could only be developed with observations and repeated experiments. This challenged the idea that if people argued for long enough the truth would be discovered. This affected the world because it made people actually work hard at something to find it out .They couldn't just say something and make that a fact. -
William Harvey
Harvey explained the circulation of blood and how the heart worked. This changed old thinking in a very dramatic way. Before this people thought that there were 2 different blood systems in the body. One brought nutrients to different parts in the body. The other brought life from the lungs to other parts of the body. With Harvey's work people realized that there was one system that did everything. This could have helped people with medicals things because it helped people learn about the body. -
Rene Descartes
Descartes stated that no assumptions will be accepted without any evidence to back it up. This challenged the old beliefs of the church. They used magic to explain things, and that's not evidence. He showed that he would not accept the church's thinking unless they could prove it. This affected the world because it made people think about everything and not just guess. -
Robert Boyle
Boyle stated that there's an inverse relationship between pressure and the volume of a gas. This changed people's views on pressure and the volume of a gas. Before this people didn't realize that they had an inverse relationship. They learned this after Boyle stated this. This helped people realize that there were many relations in science. -
Antonie van Leeuwenhoek
Leeuwenhoek discovered bacteria and called them "animalcules". His discoveries showed that everything is made up of bacteria. This led to medical things because it helped explain and prevent bacteria base illnesses. It also helped fix bacteria based illnesses. -
Gottfried Wilhelm Leibniz
Leibniz created many things to do with math. The most famous thing he created was calculus. This changed how people thought because it showed that math is important to science. Math can be used to calculate something or even building models. This affect the world because it helped people create models to help explain things. -
Isaac Newton
Newton created the 3 laws of motion;
1. Objects in motion stay in action unless acted on by another force.
2. Every change in motion is based upon the force acted on it, basically centripetal force.
3. Every action has an equal and opposite reaction.
This changes how people thought because they thought that motion was magic, now they realized that these things could be explained because of the laws of motion. This is important because it helped people think about science. -
Joseph Priestley
Priestley's biggest achievement was discovering oxygen. This changed people's opinions on what air was made of. Before this people thought that air was made of carbon dioxide and hydrogen. When he discovered oxygen people started to realize that there were more gasses than just carbon dioxide and hydrogen. This helped people discover more gasses. -
Antoine-Laurent Lavoisier
Lavoisier named oxygen, created the law of conservation of matter, and proved that matter can change forms. He believed that matter is neither created or destroyed in a chemical reaction. These changed how people thought about chemistry. He challenged what other chemists were doing. Many chemists were worried about how chemical reactions happened and how the chemicals changed. He was determined to prove that they didn't lose any weight. This helped scientists investigate chemical reactions.
