  5. Kepler • Used math to support heliocentric model • Showed elliptical rather than circular orbits • 1600 worked with Brahe

  7. Scientific Method-logical procedure • Observation • Question or problem • Hypothesis • Experiment (testing) • Conclusion: confirms or disproves hypothesis

  8. Bacon • Invented scientific method • Experimental method

  9. Descartes (day-cart) • Believed that everything should be doubted until proven with logic • “I think, therefore I am”

  10. Isaac Newton • 1687 wrote a book • Studied the Law of Gravity (wrote a book) • Continued works of Copernicus and others • Every object has an attraction to others

  11. Scientific instruments • Microscope: Janssen, 1592 • Torricelli (1643): barometer: measures atmospheric pressure • Fahrenheit (1714): thermometer • Celsius (1742): created a scale for measuring temperature.

  12. Galen and Vesalius (we-sally-us) • Galen: ancient Greek physician • Vesalius: dissected human bodies, revolutionized the way we look at medicine • 1543 wrote a book
