Chapter 16-The Scientific Revolution Flashcards
What was the nature of the relationship between mathematics, technology and the Scientific Revolution?
Technical problems caused a need for a higher understanding of math and observation methods which increased scientific activity.
Mathematics was seen as a way to explain the universe and vital to understanding nature.
The great mathematicians who contributed to the scientific revolution all believed math was the key to nature’s secrets.
What is the Ptolemaic, or geocentric, view of the universe?
The geocentric view was the belief that Earth is motionless and that the heavenly bodies have a circular orbit around Earth.
This also stated the universe’s fixed outer boundary was heaven meaning the universe was believed to be finite.
Who is Nicolaus Copernicus, what did he write, and what was his major contribution to the Scientific Revolution?
Copernicus is the man who introduced the helicoentric theory of the universe.
He wrote the book, On the Revolutions of Heavenly Spheres.
His major contribution was the Copernican System which stated that the sun was the center of the universe not the Earth, that the planets and the Earth revolved around the sun, and that the Earth rotates on its own daily axis.
What was the major contribution of Tycho Brahe to the Scientific Revolution?
-Detailed astronomical data which was the most accurate up to that time.
-His data made possible Kepler’s contribution to the Scientific Revolution.
Why was Johannes Kepler such an important figure of the Scientific Revolution?
-His three laws of planetary motion.
-His laws killed the idea of perfect circular motion + the idea that crystalline spheres revolved in circular orbits.
-His findings refuted the geocentric or Ptolemaic view of the universe.
Why was Galileo a threat to the Catholic Church?
His ideas threatened Scripture and how people viewed the universe.
What ideas of Galileo were most threatening to the Catholic Church?
-Heaven wasn’t a spiritual world but instead a world of matter.
-Humans were not the center of the universe.
-God seemed to have no specific location.
What was Galileo’s most famous work entitled?
Dialogue on the Two Chief World Systems: Ptolemaic and Copernican.
“natural philosophers”
medieval scientists
The Empyrean Heaven
-The location of God and all the saved souls
-Thought to be located on the outmost edge of the universe
Alchemy & Hermetic magic
-factor in the origins of the Scientific Revolution
-View of the intellectual elite
-fueled the desire to control the natural world
-belief humans could use mathematical magic to dominate/control/understand/employ powers of nature
Tycho Brache
recorded accurate astronomical data that made possible the discoveries of Kepler
Johannes Kepler
-discovered the 3 laws of planetary motion
-confirmed and modified the Copernican theory
William Harvey
-wrote On the Motion of the Heart and Blood
-demonstrated,
- same blood flows in both veins and arteries
-blood makes a complete circle as it passes through the body
-laid foundations for modern physiology
Robert Boyle
-one of the first scientists to conduct controlled experiments.
-Boyle’s law which states that the volume of gas depends on the pressure applied to it. He believed that matter was composed of atoms.
Antoine Lavoisier
-invented a system of naming the chemical elements
-demonstrated the rules of chemical combos
-founder of modern chemistry
Epicycles
-small circle or circular orbit that itself moves along a much larger circular orbit
Nicolaus Copernicus
-theorized the heliocentric or sun-centered conception of the universe
-proposed the Copernican System
-this system was presented in his book, On the Revolutions of the Heavenly Spheres
-for more info, read p.479-481
The Starry Messenger
-written by Galileo
-revealed planets were not perfect or unable to change but made of similar substances to Earth
The Inquisition
-the Catholic Church condemned Copernicanism and ordered Galileo to reject his thesis
-the Copernican system threatened Scripture and the way people viewed the universe
-Galileo did not accept his condemnation
-Galileo published Dialogue which was a defense of the Copernican System
-Galieo found gulity of teaching condemned Copernican system
-forced to recant his ‘errors’
Isaac Newton
-wrote Principa
-invented Calculus
- his universal law of gravitation was able to explain all motion in the universe
-first to develop a theory that combined the theories of Copernicus, Kepler, and Galileo to form a new understanding of the universe
-three laws of motion, aka the basic concepts of mechanics
- newton’s world machine p.488 or slide 27 of notes
Galen
-Greek physician
-lived in 2nd century C.E.
-teachings dominated the field of medicine in the late Middle Ages
-infulenced medieval medical world in anatomy, physiology, disease
Galen’s Doctrine of Four bodily humors
-blood-warm and moist
-yellow bile-warm and dry
-phlegm-cold and moist
-black bile-cold and dry
Paracelsus
-rejected Aristotle and Galen’s work
-believed a human being was a small replica of the larger world, aka the macromsicmic-microcosmic principle
-believed disease was due to chemical imbalances in a certain organs
-believed like cures like
“new drugs”
chemical remedies using the proper dosage of metals and minerals
Andreas Vesalius
- believed in a hands-on methods of studying and teaching anatomy
-his observations made clear the blood vessels came from the heart
