Title: Scientific Revolution


1
Scientific Revolution
2
Scientific Revolution
  • New way of thinking about natural world
  • Careful observation and willingness to accept
    beliefs
  • Navigators needed better instruments to determine
    location in open sea
  • Determined observations didnt match ancient
    beliefs

3
Heliocentric Theory
  • Nicolaus Copernicus
  • Stars, Earth and Planets revolve around Sun
  • Heliocentric sun centered
  • Didnt explain how planets orbit the way they did
  • Published On the Revolutions of the Heavenly
    Bodies
  • Contradicted religious views
  • Johannes Kepler
  • Mathematical laws govern planetary motion
  • Planets revolve sun in elliptical orbits instead
    of circles

4
More Theories
  • Galileo Galilei
  • Law of the pendulum each swing took same time
  • Aristotle said swings slower as approaches
    resting point
  • Falling objects accelerate at fixed, predictable
    rate
  • Dropped different weights, same speed
  • Telescope
  • Starry Messenger newsletter with observations
  • Jupiter had 4 moons, earths moon rough surface
  • Catholic Church warned not to defend Copernicus
  • If Church theories are wrong, people would
    question other church teachings

5
Scientific Method
  • Logical procedure for gathering and testing ideas
  • Problem, hypothesis, test and analysis
  • Francis Bacon
  • Empiricism - urged scientist to experiment,
    gather info and observe first, then come to
    conclusion
  • Rene Descartes
  • Analytical geometry linked algebra and geometry
  • Doubt until proven by reason
  • I think, therefore I am

6
Isaac Newton
  • Laws of Gravity
  • Same force rules motion of planets, pendulum and
    all earth and space matters
  • Every object attracts every other object in
    universe
  • Degree of attraction depends of weight and
    distance between them
  • Mathematical Principles of Natural Philosophy
  • Universe described as giant clock, all parts work
    together perfectly expressed mathematically

7
Scientific Rev Spreads
  • New Tools
  • Microscope
  • Barometer atmospheric pressure and predict
    weather
  • Thermometer mercury in glass
  • Gabriel Fahrenheit water freezing at 32 degrees
  • Anders Celsius water freezing at 0 degrees
  • Anatomy
  • Andreas Vesalius On the Fabric of the Human
    Body drawings of human organs, bones and
    muscles
  • William Harvey heart pumped blood throughout
    body
  • Medicine
  • Edward Jenner vaccine for small pox

8
  • Copy the timeline on p. 548 549
  • Answer these 3 questions
  • 1. How does the timeline show that the Scientific
    Revolution became a popular movement?
  • 1. How were Keplers findings able to support the
    heliocentric theory?
  • How do new discoveries help advance the
    Scientific Revolution further?

9
  • Answers
  • 1. More scientists and discoveries occurred from
    the start of the 1600s through 1714
  • 2. Kepler used mathematics to support the theory
    and prove his theory correct through accurate
    data
  • 3. New discoveries led to further questions to
    investigate
