5. New Theories  By using the works of Brahe, Johannes Kepler developed the 3 laws of planetary motion  Determined that planets travel on elliptical orbits, don’t travel with uniform speed etc.  Demonstrates that scientists did not merely accept truth but tested new theories to build and expand on their concepts

6. New Theories  Galileo further expanded our view of the universe with the telescope in his book Starry Messenger  Identified the principle of inertia  Said celestial objects made up of same material as earth  The church becomes cautious: They don’t want to claim that science is all wrong but don’t want people to give it all power either

7. Newton  Author of Principia, Newton made many great discoveries for science  Discovered universal law of gravitation  Invented Calculus to help him with his findings  Made the concept of a “World Machine” where things acted according to natural laws instead of God  Combined scientific method

8. Doctors  Galen (classical doctor) claimed body had four humors (liquids) and sickness came from an imbalance of them  Paracelsus claimed that chemicals could be used to treat and like cures like in different dosage  (Our first pharmacist)

10. Other scientists  Antoine Lavoisier: Founder of modern chemistry  Robert Boyle: Wanted controllable experiments and determined laws of gasses
