Scientific Revolution Scientists Challenge Old Assumptions
Question Everything!!! • Questioning artistic methods and experimenting with new ones = Renaissance • Questioning religion = Reformation • Questioning accepted ideas about the Earth and the universe = Scientific Revolution
Geocentric Theory Aristotle and Ptolemy – earth is unmoving object at center of universe; planets and sun move around us Church teaches that God deliberately placed earth at the center
Copernicus • Studied movement of heavens for 30 years • Heliocentric Theory • The Sun is the center of the universe, not the earth! • 1st published new idea about the universe in 2,000 yrs.
Results of Copernicus’s breakthrough… • Rethink old theories – stimulates Scientific Revolution • Catholic Church is angry – heliocentric theory challenges idea that human beings are most special to God
Kepler’s Law • 3 laws of planetary motion prove Copernicus’s heliocentric theory • Scientific Method – begin with question based on observed phenomena; hypothesis; gather and test data
Galileo Analyzed Natural World • Law of the Pendulum • Objects fall at the same speed • Built a telescope in Venice – studied stars and planets • Starry Messenger – described his observations of planets and moons
Catholic Church Reacts • Banned Copernicus’s ideas • Jesuits claim that Galileo’s ideas threaten to do more harm than Calvin and Luther put together • Pope summons Galileo to stand trial – under threat of torture he swore he had been wrong and was placed under house arrest until he died
Harvey • 1628, showed that the heart acted as a pump to circulate blood throughout the body
New Tools for Science • Microscope – 1590, invented by Zacharias Janssen • Thermometer – Galileo made one with alcohol in1603; Gabriel Farenheit created one with mercury • Barometer – Galileo’s student, Torricelli, developed mercury barometer for measuring atmospheric pressure and predicting weather
