01 - Background to the Revolution Mathematics played an important role in the scientific achievements of the sixteenth and seventeenth centuries. Nicholas Copernicus, Johannes Kepler, Galileo Galilei, and Isaac Newton were all great mathematicians who believed that the secrets of nature were written in the language of mathematics. After studying the ideas of the ancient mathematicians, they sometimes rejected these ideas. They developed new theories that became the foundation of the Scientific Revolution 02 - Revolution in Astronomy In 1543, Nicolas Copernicus published his famous book, On the Revolutions of the Heavenly Spheres. Copernicus believed in a heliocentric, or sun-centered, model of the universe. He believed that the Sun, not Earth, was at the center of the universe. The planets, including Earth, revolved around the Sun. Another mathematician, Johannes Kepler, used detailed astronomical data to create laws of planetary motion. His observations confirmed that the Sun was at the center of the universe. He also discovered that the orbits of the planets around the Sun were not circular, as Copernicus had thought. Instead, the orbits were elliptical (egg-shaped). Another mathematician, Galileo Galilei, was the first European to make regular observations of the heavens with a telescope. He discovered mountains on the Moon, four moons revolving around Jupiter, and sunspots. His observations indicated that heavenly
bodies were not pure orbs of light, but were composed of material substance like Earth. After Galileo published his discoveries in The Starry Messenger in 1610, the Catholic Church ordered him to abandon the Copernican system. The new system threatened the Church’s view of the universe and seemed to contradict the Bible. In spite of the Isaac Newton is considered the greatest genius of the Scientific Revolution. His major work, Mathematical Principles of Natural Philosophy, is also known asPrincipia (the first word of its Latin title). In the Principia, Newton defined the three laws of motion that govern both the planetary bodies and objects on Earth. The universal law of gravitation explains why the planetary bodies do not go off in straight lines but continue in elliptical orbits around the Sun. The law states that every object in the universe is attracted to every other object by a force called gravity. Newton’s laws created a new picture of the universe. It was now seen as a huge machine that worked according to natural laws.
03 - Breakthroughs in Medicine and Chemistry The science of chemistry also arose in the seventeenth and eighteenth 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. This law states that the volume of a gas varies with the pressure exerted on it. In the eighteenth century, Antoine Lavoisier invented a system of naming the chemical elements. He is considered by many to be the founder of modern chemistry 04 - Women and the Origins of Modern Science 05 - Descartes and Reason 06 - The Scientific Method
What did Galileo and Newton believe knowledge should be based on?2 Francis Bacon, Galileo, and Isaac Newton promoted the idea that knowledge should be based on 1. the experiences of past civilizations 2. experimentation and observation 3. emotions and feelings 4.
What was Galileo and Newton ideas on knowledge?Galileo determined the laws of gravity and explored the laws of motion on earth. Newton first conclusively affirmed the laws of motion and linked them with Kepler's laws of planetary motion. Before Newton, no one had demonstrated conclusively that the movements of heavenly bodies were related to terrestrial physics.
What did Francis Bacon believe scientists should?Testing hypotheses
For example, in order to test the idea that sickness came from external causes, Bacon argued that scientists should expose healthy people to outside influences such as coldness, wetness, or other sick people to discover if any of these external variables resulted in more people getting sick.
How did Galileo inspired Isaac Newton?It was a development of Galileo's ideas that led Isaac Newton to lay down his famous three laws of motion. These, plus Newton's own 'law of gravity', would provide the ultimate explanation for Kepler's elliptical orbits and really tell us what was going on.
