Scientific Revolution 1500s-1700s

1. Roots A) Before, relied on Bible or Ancients B) Renaissance led to spirit of curiosity C) Copied works from earlier Muslims D) Age of Discovery assist needs (new things)

THE SCIENTIFIC REVOLUTION NEW DIRECTIONS IN ASTRONOMY & PHYSICS  PTOLEMY: Geocentricism  NICOLAUS COPERNICUS ( ): Heliocentrisim  TYCHO BRAHE ( ): More accurate position of planets  JOHANNES KEPLER, ( ): Elliptical planetary movement

2. Nicolaus Copernicus A) Developed the heliocentric theory-idea that planets orbited the sun..not earth(geocentric) Wrote On the Revolutions of the Heavenly Bodies (1543)

HELL HEAVEN

Copernicus-Heliocentric Theory- Sun is Center of the Universe

Heliocentric

Geocentric – Earth is the center of the Universe

3. Johannes Kepler A. Mathematician B. Discovered planetary motion or that planets revolve around the sun in elliptical orbits instead of circles C. Proved Copernicus’s theory

4. Galileo Galilei A. Confirms Copernicus’s theory by use of telescope B. Challenged by Church officials C. Sentenced to prison by the Inquisition, although books spread

The Scientific Revolution Galileo Galilei ( ) - He was one of the first Europeans to build and use a telescope (he didn’t invent it!) - Galileo used a telescope to observe the moon, and saw craters. This proved that the moon was not a perfect sphere… hmm… trouble… - He saw moons on Jupiter (thus we have the Galilean Moons of Jupiter) - Aristotle didn’t mention moons… they’re they are!!! - Galileo used the scientific method to come to his conclusions; (Observe – Define – Test… Rethink, Observe, Experiment, Observe, Test…)

Galileo’s sketch of the moon as seen from his telescope A photograph of the moon “What do you think of the foremost philosophers of this university? In spite of my oft repeated efforts and invitations, they have refused, with the obstinacy of a glutted adder, to look at the planets or Moon or my telescope.” (letter to Kepler)

Galileo statement With Sincere heat and unpretended faith I abjure, curse, and detest the aforesaid errors and heresies (of Copernicus) and also every other error contrary to the Catholic Church.

5. Isaac Newton (Galileo) A. Law of Gravity-all matter on earth and in space are ruled by the same forces of gravity B. “A Mechanical Universe” C. Mathematical Principles of Natural Philosophy

Newton’s Theory of Universal Gravitation Newton and the Apple (The apple never fell on his head, but sometimes a stupid person will say that, trying to be funny.) Newton asked good questions  the key to his success. Observing Earth’s gravity acting on an apple, and seeing the moon, Newton asked whether the Earth’s gravity extends as far as the moon.

6. William Harvey A. Publishes On the Motion of the Heart and Blood in Animals in 1628 B. Said heart acted as a pump to circulate blood throughout the body

7. Medicine A) Louis Pasteur-discovers bacteria in mid 1800s- Pasteurization

B) Edward Jenner-smallpox vaccination

Early Smallpox Vaccination Testing

8. Scientific Theory or Method A) Francis Bacon-in order to reach scientific truths one must carry out experiments

B) Rene Descartes-must rely on logic and mathematics to reach scientific truths (“I think, therefore I am”)

Scientific Method at work Galileo dropped two stone off the Eiffel Tower one was heavier than the other but they dropped at the same speed. Disproving Aristotles theory.

Understanding With its emphasis on reasoned observation and systematic measurement, the scientific revolution changed the way people viewed the world and their place in it
