The Scientific Revolution began based on careful observation and the willingness to question beliefs that at that time were unquestionable - such as the geocentric theory -.
During the Age of Exploration many new territories were discovered, in the Americas for example, this fueled the research in astronomy and math to make navigation easier and more precise.
This new development, Copernicus developed the Heliocentric Theory in 1543, despite the pressure the Church put on him. After him came Tycho Bahe who recorded the movement of the planets and Johannes Kepler who proved planetary orbits. All of them reinforced the Heliocentric Theory. Later, in 1609, Galileo Galilei, who supported Copernicus ideas created the telescope. His findings angered the Church who called him before the Inquisition.
Further in time, the Scientific Method was developed, which made a revolution upon science and the world. Many were responsible for the development of the Method, Francis Bacon was one of them, he promoted “empiricism” also known as an experimental method. But the most famous one is Rene Descartes, the one that sustained that everything should be doubted until proven with evidence, he defended the use of algebra and geometry, math and logic to prove things.
Later, Isaac Newton developed the Theory of Gravity in 1687, he is without a doubt one of the most important scientists in history.
This these developments the Scientific Revolution spread and became not-stoppable. The microscope was invented in 1590, this made possible bacteria and blood cells to be observed and other creations became possible in medicine and other areas.
