The scientific revolution

THE SCIENTIFIC REVOLUTION


Introduction

INTRODUCTION:

During the Middle Ages “natural philosophers” as medieval scientists were known, did not make observations of the natural world. They relied on a few ancient authorities – especially Aristotle – for their scientific knowledge. A number of changes in the 15th and 16th centuries caused them to abandon their old views and develop new ones.


The big question

THE BIG QUESTION:

How did the Scientific Revolution change people’s view of the natural world?


New developments

NEW DEVELOPMENTS

  • Newly discovered Greek works by Ptolemy, Archimedes, and Plato

  • The printing press helped spread new ideas

  • The invention of the telescope, microscope, and other measuring instruments

  • New developments in mathematic


Two types of scientific thinking

Two Types of Scientific Thinking

  • Inductive reasoning:

    • Proceeding from the particular to the general

      • Ex. Every time I eat oranges I get sick, therefore I get sick because I eat oranges.

  • Deductive reasoning:

    • Working from the general toward the specific

      • Ex. All oranges are fruits fruit grows on trees, therefore all oranges grow on trees


A new scientific philosophy

A New Scientific Philosophy

  • Rationalism:

    • The belief that reason is the chief source of knowledge


Roots of scientific revolution

ROOTS OF SCIENTIFIC REVOLUTION

  • can be found in the Renaissance with the works of Copernicus, Galileo and other scientists

  • Rejected traditional authority and church teachings in favor or direct observation of nature

  • Scientific method – people observed nature, made hypotheses about relationships, and then tested through experiments.


Opposing theories

OPPOSING THEORIES

GEOCENTRIC THEORY (Ptolemaic)

This system places the Earth at the center of the universe. The Earth is fixed at the center of concentric spheres, one inside the other, in which the heavenly bodies rotate around the earth.


Heliocentric theory copernican

HELIOCENTRIC THEORY (COPERNICAN) –

  • This theory places the sun (not the earth) at the center of the universe, with planets revolving around the sun. The moon, however, revolves around the earth, and the earth rotates on its axis.


Galileo galilei

Galileo Galilei

  • Italian astronomer

  • Widely used telescopes and conducted tests on the motion of objects to find general principles of physics

  • His idea was that the planets were composed of material substance

  • Wrote “The Starry Messenger”


Nicholas copernicus

Nicholas Copernicus

  • Polish astronomer

  • Idea was that the sun was the center of the universe, and the moon revolved around earth

  • Wrote “On the Revolutions of the Heavenly Spheres”


Johannes kepler

Johannes Kepler

  • German astronomer, scientist, and mathematician

  • Idea was that the orbits of planets were not circular, but elliptical

  • Was able to prove this mathematically


Sir isaac newton

Sir Isaac Newton

  • English scientist and mathematician, and the most influential thinker of the

    Scientific Revolution

  • laws of gravity and motion

  • Wrote “Principia Mathematica”

    (connected the speed of falling

    objects on Earth to the movement

    of planets.

  • Led to hope that the universe acted according to certain fixed and fundamental laws


William harvey

William Harvey

  • Scientist and physician

  • He wrote a book called “On the motion of the Heart and Blood” published in 1628.

  • He showed that the heart was the beginning point in the circulatory system, not the liver. He discovered that the same blood flows in both veins and arteries, and most important, that blood makes a complete circuit as it passes through the body.


Robert boyle 1627 1691

Robert Boyle (1627-1691)

  • Irish Chemist (sometimes knows as the “Father of Chemistry)

  • Conducted controlled experiments on gases at different temperatures and pressures.

  • Pioneered work on the properties of gasses, which led to Boyle’s law.

  • The law states that the volume of a gas varies with the pressure exerted on it.

  • Distinguished mixtures from compounds


Francis bacon

Francis Bacon

  • English philosopher

  • Invented the scientific method

  • He wanted science to benefit industry, agriculture, and trade.

  • He was more concerned with practical matters than pure science.
