The Scientific Revolution
Term | Definition |
---|---|
Scientific Revolution | Through the 15th up to the 18th century there was a tremendous development in mathematics, physics, astronomy, biology, medicine and chemistry. |
Nicolaus Copernicus | An astronomer who studied the stars and the planets and developed the heliocentric theory of the universe which stated that the sun was the center of the universe and the planets and moons moved around the sun. He couldn't prove his theory. |
Heliocentric Theory | The idea that the sun is the center of the universe. And the planets and moons move around the sun. The theory was developed by Copernicus but proved by Kepler. |
Johannes Kepler | A mathematician who proved that the heliocentric theory of the universe was true (Copernicus' idea) by proving that the planets were moving in elliptical orbits around the sun. |
Planetary Motion | Part of Kepler's proof that the sun is at the center of the universe was done by proving that planets are moving around the sun in elliptical orbits. |
Galileo Galilei | Scientist who helped improve the design for the telescope. He also used his telescope design to study the surface of the moon and the sun. He suggested that they weren't perfectly flat surfaces, challenged the Catholic church's beliefs & was arrested. |
Telescopes | A device used to look at the moon, planets, and stars. The use of the telescope allowed people like Kepler to be able to prove planetary motion. |
Scientific Method | Question, Hypothesis, Experiment, Conclude. The idea for the scientific method came from Francis Bacon |
Isaac Newton | Described and proved the law of gravity |
Gravity | The forces that keep us tied to the Earth, Newton would later prove that gravity also affects planets and stars. |
William Harvey | The doctor or physician who discovered the circulatory system in the human body and began to map it throughout the body. |
Circulatory System | The part of your body responsible for circulating blood pumped by your heart, discovered in 1628 by William Harvey |
Reasons why the scientific revolution began when it did: | 1. Focus on careful observation 2. Willingness to question old beliefs and the Church (after the Reformation) 3. European explorers were seeing new things that the Church couldn't explain so people turned to science for answers |
Effects of the Scientific Revolution | 1. Emphasis on reason or logic 2. Formulation of the scientific method 3. Expansion of scientific knowledge |
