Document Summary
18th century - scientific revolution: alchemy(religion[spiritual powers} + science) --> Alchemists discovered brandy by distilling wine, phosphorus. Nicolaus copernicus - developed the heliocentric model of the universe (sun is the center, and that the earth revolves around it. ) Despite his calculations, many scholars disagree with his theories and continue to believe in the geocentric model proposed by the ancient greek ptolemy 1500 years earlier. Galileo galilei - continued copernicus" work by observing the skies with a homemade telescope. Although he was able to prove copernicus correct, his work was rejected by the church and he was forced to recant (take back) or face execution. Isaac newton - built upon the earlier work of copernicus/galileo and used math to describe gravity as the force that keeps planets revolving around the sun. He also explained that this same force is what causes objects to fall to earth. Rene descartes - french intellectual who challenged traditional ideas.
