SCIENTIFIC REVOLUTION & THE ENLIGHTENMENT
BACKGROUND to the REVOLUTION
• Medieval scientists were known as “natural philosophers”
• Meaning they did not make observations of the natural world
• Aristotle was relied on for scientific knowledge• Due to the Renaissance, philosophers were able to
learn Greek and Latin
NEW INSTRUMENTS
• Telescope• Microscope• Printing Press• Thermostat• Barometer
MATHEMATICS & ASTRONOMY
• Played an important role in the scientific achievements• Great mathematicians believed the secrets of nature were found
in the language of mathematics– Nicholas Copernicus– Johannes Kepler– Galileo Galilei– Isaac Newton
• Their theories became the foundation of the Scientific Revolution
• Discoveries in astronomy changed how Westerners viewed the universe
PTOLEMAIC SYSTEM
• From the ideas of second century A.D. philosopher, Ptolemy
• System is called geocentric, which places the Earth as the center of the universe
• The universe is a series of concentric spheres• The Earth is fixed as the center of these spheres
COPERNICUS
• In 1543, he published a book, On the Revolutions of the Heavenly Spheres
• Believed in a heliocentric, sun-centered, model of the universe
• He believed that the Sun, not Earth, was at the center
• The planets revolved around the Sun
JOHANNES KEPLER
• Used detailed astronomical data to create laws of planetary motion
• Observation confirmed that the Sun was at the center of the universe
• Also discovered that the orbits of the planets around the Sun were not circular, but elliptical
GALILEO GALILEI
• First European to make observations of the heavens with a telescope
• Discovered mountains on the Moon, four moons revolving Jupiter and sunspots
• His efforts threatened the Catholic church therefore ordering him to abandon the Copernican system
• However, most astronomers had come to accept the heliocentric model
ISSAC NEWTON
• Greatest genius of the Scientific Revolution• In his work, Principia, he defined three laws of
motion that govern both the planetary bodies and objects on Earth
• Universal law of Gravitation1.2.3.
CHEMISTRY
• The science of chemistry also arose in the 17th and 18th centuries
• Robert Boyle was one of the first scientists to conduct controlled experiments
• His work on the properties of gas led to Boyle’s Law• Boyle’s law states that the volume of a gas varies
with the pressure exerted on it• Antoine Lavoisier is considered to actually be the
founder of modern chemistry
WOMEN & SCIENCE
• Margaret Cavendish– One of the most prominent female scientists– Critical of the belief that humans, through science, were
masters of nature• Maria Winklemann– Most famous female astronomer in Germany– Discovered the comet– Denied a job at the Berlin Academy because she was a
woman
THE SCIENTIFIC METHOD
• The scientific method was created during the Scientific Revolution
• It is a systematic procedure for collecting and analyzing
• Francis Bacon developed the scientific method– Believed scientists should use inductive reasoning to
learn about nature– Believed that science could give humans power over
nature
The enlightenment
PATH TO THE ENLIGHTENMENT
• The Enlightenment was an 18th century philosophical movement of intellectuals
• Influenced by John Locke and Isaac Newton• The intellectuals of the Enlightenment were known as
philosophes• To these philosophes, the purpose of philosophy was

US Constitution
PHILOSOPHERS
• Voltaire (Francois-Marie Arouet)– Greatest figure of the Enlightenment– Wrote pamphlets, novels, plays, letters, essays and
histories– Known for his criticism of Christianity – Believed in deism, based on natural law and reason– In the Deists’ view, a mechanic God had created the
