1. Global Connections Unit 6
Scientific Revolution

2. The Scientific Revolution
Faith and science clash (different philosophies) (truth over superstition and magic)
In this “revolution” we find the origins of the modern world brought about by human inquiry
Nature to be explored in its own right not as evidence of God’s creative powers

3. A new way of thinking Francis Bacon (1561-1626)
Suggests experimentation to learn about the natural world
Inductive not deductive reasoning
Father of modern Empiricism and the scientific method
Rene Descartes ( )
“I think therefore I am”
Rationalism: human reason as the source of knowledge

4. The changing view of the universe
The old view: (4th Cen. BC): Science as a branch of theology (humans at center etc..)
Geocentrism: Aristotle came up with it and Ptolemy figured out rules to explain planetary motion
10 separate crystals with planets embedded in them moved around the earth
Angels moved the spheres in perfect circles

5. Geocentrism

7. Nicholas Copernicus (1473-1543)
Polish cleric
First to challenge Geocentrism in his book “On the Revolutions of the Heavenly Spheres” (published after his death)
Only challenged the Geocentric idea but his work led to more questions being asked

8. Johannes Kepler ( )
Assistant of Brahe (Math genius) Used Brahe’s data to develop three laws of planetary motion
Ellipses not circles
Planets vary their speeds during their orbits based on distance from sun
Time of orbit is based on distance from sun

9. Galileo Galilei (1564-1642) 1609 developed the 1st telescope
1632 published “Dialogues on the 2 great systems of the Universe”
Conflict with Pope Urban VIII
1633 ordered to repudiate his views
Also did work in physics (acceleration of falling bodies)

10. Galileo and the Inquisition

11. Galileo has been called the "father of modern observational astronomy", the "father of modern physics",the "father of science", and "the Father of Modern Science." The motion of uniformly accelerated objects, taught in nearly all high school and introductory college physics courses, was studied by Galileo as the subject of kinematics. His contributions to observational astronomy include the telescopic confirmation of the phases of Venus, the discovery of the four largest satellites of Jupiter, named the Galilean moons in his honour, and the observation and analysis of sunspots. Galileo also worked in applied science and technology, improving compass design

12. Newton’s synthesis (1642-1727)
Author of Mathematical Principles of Natural Philosophy”
Universal Gravitation: Every object in the universe is attracted to every other object by a force called gravity
Inertia: Objects in motion remain in motion unless acted upon by an outside force…

13. The study of living things
Andreas Vesalius: “The father of modern anatomy”
William Harvey: Circulation of blood
