Roger Bacon
Roger Bacon was an English philosopher and scientist. He was one of the earliest person to think outside the traditional beliefs. But he was still influenced by the thinking of that time. He was important to the scientific revolution because he could have inspired other people to try to find the truth and support the scientific revolution. -
1543
Nicolaus Copernicus
Nicolaus Copernicus was the person who started to argue that the sun was the center of the universe, instead of the earth. (Heliocentric theory). He published his theory in 1543. However, he had no prove of his argument without mathematics or instruments. Copernicus had started a very important theory of the nature. If Copernicus didn't publish his theory, Kepler and Galileo couldn't have developed it. -
1543
Andreas Vesalius
Vesalius was one of the first people to study anatomy, and investigating how the human body was constructed. In 1543 he published his book explaining the human body with illustrations, to understand more the ideas. This could have developed the medicine we have now, doctors could know what the patient had, where the pain is located and why based on the information in this book. It also changed people's ideas of how the body functioned, instead of just accepting like facts the old beliefs. -
1563
Tycho Brahe
In August 1563, aged 16, Tycho an astronomer started his first book of astronomical observations. He was also a supporter of the heliocentric theory. He made a lot of accurate observations of planetary positions that were very useful to other scientists and astronomers. All of his observations were made with the naked eye. His discoveries (planetary observations) were a great input to astronomy. -
Zacharias Jansen
Is believed that Zacharias Jansen with the help of his father invented the first compound microscope. It could magnify things by ten times. Jensen's microscope was an important advance from single lens magnification. After years there were a lot of developments that allowed the observation of microorganisms. Without the microscope, we wouldn't know what a bacteria or a cell is. Is important in science to know and observe the smaller things in nature. -
Hans Lippershey
Hans Lippershey is known for the earliest written record of a refracting telescope in 1608. This is an important event because with the telescope scientists could see further than with the human eye could see. This was a great invention to see and study the planets, stars and other space objects. Without the telescope we couldn't know what we are, we wouldn't know our solar system or galaxy. -
Johannes Kepler
Kepler used models, observations and mathematics to prove Copernicus theory, (he also made corrections) and published his laws of planetary motion in 1609.
This was an important event because compared with Copernicus who didn't have the evidence, he had evidence, proves, and studies to prove his arguments. With this book, people started to believe and consider more possibilities, and have other ideas about science, other than attaching to their religion beliefs . -
Francis Bacon
Francis Bacon is known for developing the Baconian method, the investigative method in Bacon's book Novum Organum published in 1620, was influential for the development of the scientific method. This was an important event because the Baconian method was the process people had to follow to make conclusions from observations and to make good facts. -
Galileo Galilei
Galileo also supported Copernicus theory. He built his own telescope and was able to see things that no one else had seen. He published his findings confirming the heliocentric theory in 1632. He also proved that all objects, heavier or lighter, fell at the same speed. His input was important because his discoveries formed the basis of science, the study of objects in motion challenging the traditional beliefs. -
Rene Descartes
Descartes created an important philosophy based on the fact that "no assumptions should be accepted without question", and all assumptions had to be proven on the basis of facts. This was an important statement because instead of believing in what was said for no reason, you had to support that with facts to prove the true. Descartes was one of the first people to use rationalism. -
Robert Boyle
In 1662 Robert Boyle showed that temperature and pressure affected the space that a gas occupies. Boyle's law connects a lot of things in science and gives us important information about the behavior of gases. In general Boyle's law is a part of the basic composition of today's modern chemistry. -
Antonie Leuuwenhoek
Anton van Leeuwenhoek was a scientist, known for his development and improvement of the microscope and for his contribution towards the study of microbiology. In 1676 he observed water closely and saw tiny microorganisms for the first time. This event is relevant to science because after that discovery, microbiology was used to prevent diseases caused by bacteria and other organisms. -
Isaac Newton
In 1687 Isaac Newton published his book supporting Copernicus theory and explaining motion. Based on his studies, he invented the universal gravitation law, where all objects attract each other. He also invented the laws of motion with mathematical means of measuring motion. Newton's work was very important because with his laws he established the base of science and explained the movement of all things in space and earth. Evidence to any scientific argument related with motion. -
Antoine Lavoisier
Lavoisier was the person that showed people that fire resulted when a substance combined with oxygen. He proved matter can change form but not be destroyed or created. This is known as the law of conservation of matter. Is one of the most important basic idea in the study of chemistry and influenced today's science. -
Joseph Priestley
This was the man who discovered oxygen in 1774. This was an important event because this discovery led to many important conclusions and new experiments in science. For example the oxygen tanks used for astronauts.
