DO NOW True or False: The chalkboard is white.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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?
