  3. Nicolaus Copernicus • Old Belief: Geocentric theory • New Theory: Heliocentric Theory – the sun is at the center of the universe • Findings: Maps the sky for 20 years • Reactions: Disbelief and outrage – “this goes against the church’s teachings!” • Impact: Father of modern Astronomy

  4. Tycho Brahe & Johannes Kepler • Old Belief: Geocentric theory (perfectly circular orbits, universe never changes) • New Theory: Geo-Heliocentric theory, elliptical orbits, universe is changing • Findings: View a supernova, use complex mathematics • Reactions: Disbelief • Impact: No credit until after death

  5. Galileo Galilei • Old Belief: Geocentric theory, universe is perfect & unchanging • New Belief: Universe is imperfect & changing • Findings: Creates telescope to view the heavens • Reactions: Attacked by the Inquisition – spends rest of life under house arrest • Impact: Discovery of Jupiter’s moons, sun spots, and visual proof of Helocentricity

  6. Isaac Newton • Old Belief: Geocentric theory, spirits control the movement of heavenly bodies • New Belief: Heliocentric theory, gravity • Findings: Complex mathematics prove Newton’s “3 laws” • Reactions: wide-spread acceptance • Impact: Father of engineering and physics

  7. Galen of Pergamum • Old Belief: Body is controlled by spirits and humors • New Belief: Body can be understood through examination • Findings: Dissection of animals to learn about human body • Reactions: Acceptance – God made all of us after all • Impact: Founder of anatomy – theories untested for over 1,000 years!

  8. Andreas Vesalius • Old Belief: Dissection of bodies is a sin • New Belief: Human dissection is essential to medicine • Findings: Dissected human corpses to prove theories • Reactions: Acceptance – can’t argue with physical evidence • Impact: Founder of modern science of anatomy and physiology

  9. William Harvey • Old Belief: Food is turned into blood in the heart • New Belief: The heart constantly recycles the same blood • Findings: Observed a still-beating heart • Reactions: Many unwilling to accept his theories • Impact: Father of physiology – how the body works • Capacity of heart =1.5 ounces • Each pump = , 1/8 of blood expelled. • Estimates 1/6 oz. of blood went through heart each pump • Estimates heart beats 1000 times every 30 mins • This would require 10 pounds 6 ounces of blood to be created in 30 mins • Liver would have to produce 540 pounds of blood in a day.
