The Heliocentric Theory Scholars began to dispute the claims of the geocentric theory Nicholas Copernicus, a Polish cleric and astronomer, was troubled by this theory Copernicus focused on an ancient idea that the sun was the center of the universe He studied the stars for 25 years and concluded that the sun was at the center Called the Heliocentric Theory He did not publish his findings until the end of his life because he feared ridicule and persecution

Galileo Galilei At 17 years old Galileo disproved one of Aristotle’s theory’s He then discovered that a falling object accelerates at a fixed and predictable rate He disproved Aristotle’s idea that heavier objects fall faster Galileo had learned of a lens that could see far off objects He then improved the invention creating the telescope in 1609 Which he used to study the heavens Both Catholic and Protestant leaders feared Galileo’s findings Galileo was warned not to support these ideas When he ignored the warnings, he was summoned to Rome and the Inquisition He read a signed confession that his findings were false Lived under house arrest until his death
7
Scientific Method All of the new theories and ideas developed led to the development of the scientific method A logical procedure for gathering and testing ideas Two men Francis Bacon and Rene’ Descartes helped create this approach They believed scientists should discard old ways of thought and pursue actual proof Modern science is based on these foundations Observation, experimentation, scientific reasoning, to form conclusions

Sir Isaac Newton A mathematician and Physicist from Cambridge He studied the theories of those before him, Galileo, Copernicus, etc… Newton combined all of the ideas about space and motion into 3 laws The most important law was “the Law of Universal Gravitation”
