3. Impact on Your Lives • Have you learned the scientific method? It was developed during the Sci. Revolution! • Enlightenment philosophers championed the natural rights of humans, setting the stage for the rise of Democracy • Other ideas from the Enlightenment strongly influenced the Founding Fathers and serve as the backbone of the American system of government

4. Section1: The Scientific Revolution Main Idea: The scientific revolution gave Europeans a new way to view the human races’ place in the universe.

5. Revolution in Astronomy • Ptolemaic System • Ptolemy was an ancient Greek/Egyptian astronomer who lived in the 2nd century CE • Geocentric model of the universe • Geo = Earth • Centric = center

6. Ptolemaic System • Planet Earth is at the center of the universe and does not move • Universe is a series of concentric spheres • Developed during the Middle Ages (1100-1500 CE)

7. Nicholas Copernicus • Polish mathematician • Published On the Revolution of Heavenly Spheres in 1543 • Argued Ptolemaic system was too complex • Proposed a heliocentric model of the universe • Helio = sun • Argued the perceived movement of the sun was really the Earth rotating on its axis and moving on its orbit around the sun

8. Johannes Kepler • German mathematician • Expanded upon Copernicus’ research & developed laws of planetary motion • The sun IS the center of the universe • The orbits of planets around the sun were an ellipse (egg)

9. Galileo Galilei • Italian astronomer & mathematician • 1st European to make regular observations with a telescope • Mountains on the moon • Four moons revolving around Jupiter • Sunspots • Heavenly bodies were made of substances similar to those found on Earth, not light!

11. Sir Isaac Newton • English mathematician • Three Laws of Planetary Motion • Universal Law of Gravitation • Every object in the universe is attracted to every other object by a force called gravity • Saw the universe as a huge machine operating according to natural laws • This idea dominated the modern worldview until the mid 20th century

12. Chemistry & Medicine • During the Middle Ages experts still relied on the work of 2nd century Greek Galen • He used animal dissection to develop his ideas of human anatomy – and they were often wrong!

13. Andreas Vesalius • Published On the Fabric of the Human Body in 1543 • His discoveries made by dissecting human cadavers • Detailed observations of organs and structure of the human body • Overturned many of Galen’s theories, but still believed different types of blood flowed through veins & arteries

15. Beginnings of Chemistry • Robert Boyle • Pioneer in controlled experiments • Studied the properties of gasses: Boyle’s Law • Antoine Lavoisier • Developed a system of naming elements • Regarded as the father of modern chemistry

16. Margaret Cavendish • One of the most prominent female scientists of the 1600s • Critical of the belief that humans were masters of nature through scientific knowledge

17. Women & Science in Germany • Between 1650-1710 nearly 15% of all German astronomers were female • Trained by their husbands and fathers at family observatories • Maria Winkleman: most famous German female astronomer • Despite her academic credentials she was denied a teaching position at the Berlin Academy b/c they feared hiring a woman would set a bad example

18. Rene Descartes & Reason • 17th century French philosopher • Considered the father of rationalism • Rationalism: belief that reason is the main source of human knowledge; Our ability to think and reason through problems allows the human race to acquire knowledge
