1. Scientific Revolution Scientists
Revolutioned the World!

2. Raphael’s School of Athens

3. Nicholaus Copernicus (1473-1543)
Polish Astronomer and Mathematician
proposed heliocentric model of the universe - Sun at the center of the universe. Earth was just one of several plants that revolved around the sun
many rejected heliocentric theory - how could things fall if the earth was moving?
the Church banned it the following century
Ptolemy's
Geocentric View
Copernicus'
Heliocentric View

4. Johannes Kepler (1571-1630) German Astronomer and Mathematician
Used his mentor, Brahe’s ideas (built off of Copernicus’ theory) calculated the orbits of the planets revolving around the sun
demonstrated that planets did not move in perfect circles but in orbit called an Ellipse

5. Galileo Galilei (1564-1642) Italian Astronomer
Used technology by Dutch lens grinder - invented a telescope
first to see mountains on the moon and sunspot
observed the four moons of Jupiter moving around the planet
put through Inquisition (trial by the Church) because his observations contradicted ancient views and Christian teachings (heresy)
Threatened with death, he agreed to say that the earth stood motionless at center of universe
It does move

6. Sir Isaac Newton ( )
English Mathematician, Philosopher, and astronomer
discovered the law of gravity (observed an apple falling from tree –wondered about the force that pulled that apple to earth)
said that nature followed universal forms, all motion in the universe can be measured and described mathematically
Define Gravity- force that holds planet in orbit around the sun

8. Sir Francis Bacon (1561-1626) English Scientist
argued that truth is not known at the beginning of inquiry (questioning) but at the end after a long process of investigation
Stressed experiment and observation
wanted science to make life better for people by leading to practical technologies
came up with scientific method
Define Hypothesis- educated guess about answer to a problem

9. Scientific Method: Make an observation, Create a question,
create a hypothesis,
conduct an experiment,
evaluate, (accept or alternate) your hypothesis
