Scientific revolution

Scientific Revolution

Ch. 10

Mrs. Newman

World History


Ptolemy

Ptolemy

  • Greatest astronomer (2nd. Century A.D.)

  • Ptolemaic system- geocentric theory (Earth is at the center of the universe)

  • Theory supported by the Church

Egyptian, wrote in Greek


Scientific revolution

Ptolemaic System


Copernicus

Copernicus

  • Book- On the Revolutions of the Heavenly Spheres

  • Heliocentric theory (sun is at the center of the universe, NOT Earth)

  • Theory angered The Church

1543, from Poland


Kepler

Kepler

  • German mathematician

  • Studied planetary motion & concurred w/Copernicus that the Sun was at the center of the universe

    • Orbits of the planets around the Sun were not circular (were elliptical- egg shaped)—Kepler’s First Law


Galileo

Galileo

  • Italian

  • Taught mathematics

  • 1st. European to use a telescope

    • Discovered mountains on the Moon, four moons revolving around Jupiter, & sunspots


Church response

Church Response

  • The Church ordered Galileo to recant his findings (contradicted the Bible & The Church’s beliefs)

    • He did so, but lived the rest of his life under house arrest


Newton

Newton

  • Professor of mathematics

  • Principia

    • Defined 3 laws of motion that govern the planetary bodies & objects on Earth

    • Universal Law of Gravitation (gravity)


Medicine

Medicine

  • Vesalius

    • On the Fabric of the Human Body (1543)

    • Dissected human bodies

  • Harvey

    • Showed the heart and veins/arteries

Harvey’s sketches of

veins & arteries

Chemistry

Chemistry

  • Boyle

    • One of the 1st. scientists to conduct controlled experiments

    • Boyle’s Law- volume of a gas varies with the pressure exerted on it

  • Lavoisier

    • Invented a system of naming the chemical elements (founder of modern chemistry)

Lavoisier conducting an experiment on respiration in the 1770s.

An animation of Boyle's Law, showing the relationship between volume and pressure when mass and temperature are held constant.


Bellringer write questions and answer

Bellringer *write questions and answer*

  • Define geocentric. Who created that system?

  • Define heliocentric. Who created that system?

  • Who had the idea of gravity?


Women during the scientific revolution

Women during the Scientific Revolution

    • Aristocratic family

    • Critical of the belief that humans, through science, were the masters of nature

  • Maria Winkelmann

    • German astronomer

    • Discovered a comet

    • Denied a position as an assistant astronomer


Descartes

Descartes

  • French philosopher

  • Discourse on Method (1637)

    • “I think, therefore I am”

    • Father of modern rationalism- reason is the chief source of knowlege


Scientific method

Scientific Method

  • Systematic procedure for collecting & analyzing evidence


Francis bacon

Francis Bacon

  • English philosopher

  • Stated scientists should use inductive reasoning to learn about nature

    • Practiced the Scientific Method

    • Wanted science to benefit industry, agriculture, and trade
