Scientific Revolution 1470-1730

PtolemyGeocentric Theory
Earth-centered theory
IN the A.D. 100s, Ptolemy believed that the Earth was the CENTER of the universe.
Heliocentric Theory
1500s time frame
Nicolaus Copernicus argued that the sun was the center of the universe.
“Helio” is the Greek word for “sun”.
People paid little attention—it just didn’t make sense
The Scientific Method
Johannes Kepler and Planetary motion
PROVED COPERNICUS RIGHT
Brilliant mathematician who used models, observation and mathematics to test Copernicus's heliocentric theory
Published Laws of Planetary Motion in 1609
Galileo…The Heretic?
I do not feel obliged to believe that the same God who endowed us with sense, reason, and intellect intended us to forgo their use.
Galileo Galilei and his telescope
Italian scientist improved the telescope
Produced evidence that Copernicus was correct
Saw that the moon was not a smooth surface and that Jupiter had moons
Used experiments and mathematics to disprove that heavy objects fall faster than light ones

Isaac Newton and his law of gravity
Newton realized the force that holds the planets in their orbits and the force that causes objects to fall to Earth are one and the same.
Huge impact on the science of his time
You can also thank him for developing calculus
Galen
William Harvey and the heart
English physician that studied the circulation of blood and how it moved through the veins and arteries.
Also studied the heart
VesaliusThe Father of Modern Anatomy
Flemish scientist

Performed his own studies to see how human body was constructed

Published a book called On the Fabric of the Human Body

Helped people gain ideas on how the body worked

During his research Vesalius showed that the anatomical teachings of Galen, revered in medical schools, was based upon the dissections of animals even though they were meant as a guide to the human body.
The Impact of the Scientific Revolution
Technology- all weather roads improve year-round transport and trade
New designs in farm tools increase agricultural productivity
Improved ship design lower transport costs
