Objectives • Explain how new discoveries in astronomy changed the way people viewed the universe. • Analyze the contributions that Newton and other scientists made to the Scientific Revolution.

Scientific Method • Problem=hypothesis=data=conclusion • Bacon moved away from reliance on ancients, stressed experimentation and observation • Descartes “I think therefore I am” • Discourse on Method(1637) • Everything within human reason
Scientific Revolution • Scientific Method needed new materials • Perfected Microscope by Leeuwenhoek(1590) • Fahrenheit and Celsius • Dissection of bodies • On the Structure of the Human Body • Vesalius, first accurate and detailed study of human anatomy • Harvey, circulation of blood and the heart • Inoculations
