1. DO NOW
True or False:
The chalkboard is white.

2. The Scientific Revolution
1500s-1600s – Changed the World!
People draw conclusions & make decisions based on Experiments and Observations
No more “blind faith” – don’t just accept an idea as being true…
Prove it!!!
Opposition to ideas: Church, Rulers

3. Influences… Renaissance Curiosity about world Knowledge spreads
Reformation
Challenged traditional ideas

4. Challenged Old Ideas: What was true? Aristotle’s theories The Bible
And now? They’re challenged because:
People observe new ideas about how the world works

5. ? The 1st Challenge What is at the Center of the Universe?
Sun – OR – Earth ?

6. Geocentric Theory Earth-Centered Universe Sun revolves around it
The Church/Bible/Aristotle support this
It must be true then…right?

8. Heliocentric Theory Sun-Centered Universe Earth revolves around it
Astronomers think Geocentric is wrong

9. Heliocentric Theory Sun-Centered Universe Earth revolves around this
Astronomers think Geocentric is wrong

10. Nicolaus Copernicus 1500s: Polish scholar/astronomer
Discovered Heliocentric Theory
Doesn’t publish findings until last year of life (1543)
On Revolutions of Heavenly Bodies
Feared persecution from Church

11. Brahe & Kepler Tycho Brahe Believed Copernicus
Observed planets & recorded data
Johannes Kepler
Brahe’s assistant
“Laws” based on Brahe’s data
Proved Heliocentric

12. Galileo Galilei Brilliant Italian scientist Speed of Falling objects
Built a telescope (had never seen one)
Starry Messenger

13. Observations proved Heliocentric
CONFLICT w/the Church
Findings challenge Church teachings
ON TRIAL (faces death penalty)
Takes back his ideas
Says Copernicus was wrong

14. Isaac Newton English Mathematician Discovery: Gravity
Keeps planets in motion
Objects fall to ground
Newton’s Laws of Gravity

15. The Scientific Method 1600s – New approach to science and discovery
Don’t “accept” truths – discover them for yourself
Knowledge should be based on:
Experimentation
Observation

16. Bacon & Descartes 2 Political Thinkers advanced the Scientific Method:
1) Bacon: English politician
People must understand the world!
Gather & analyze info!
2) Descartes: French politician
Reject “old” assumptions about “truth”
Go find out for yourself

25. Impact!!! People Realize 2 Things
We don’t know everything about the world!
The Church and Kings are not always right about everything either!
So they start to think…
WHAT ELSE DON’T WE KNOW?
