Scientific Revolution
A major change in European thought, starting in the mid-1500s, in which the study of the natural world began to be characterized by careful observation and questioning of accepted beliefs.
Foundations of the Scientific Revolution
The Renaissance inspired curiosity about the world and the way things worked.
The Reformation encouraged new ways of thinking about God and salvation.
The Age of Exploration created an awareness of new places, people, animals, and plants that were previously unknown, including advancements in technology that helped people better understand their surroundings.
Ways of thinking about the Universe
Medieval View
Geocentric Theory
The earth is an immovable object located at the center of the universe
The sun, moon, and planets all revolved in circular orbit around the earth
Ways of thinking about the Universe
Revolutionary View Heliocentric Theory - 1543
Established by Nicolaus Copernicus: A sun-centered theory, planets and stars revolve around the sun
Johnnes Kepler demonstrated that the orbit of the planets was elliptical, not circular
Galileo built the telescope in 1609 and used it to study the stars. He used his own telescope to discover that Jupiter had four moons and the sun had dark spots. Published his findings in his book “The Starry Messenger”
Scientific Method
A logical procedure for gathering and testing ideas.
1. Stating a question/problem arising from an observation.
2. Forming a hypothesis, or assumption that is not yet proven.
3. Testing a hypothesis in an experiment or on the basis of data.
4. Analyzing and interpreting data to reach a conclusion (either proving or disproving the hypothesis).
Sir Isaac Newton
Laws of Motion Objects remain in state
unless force acts upon them
Acceleration happens when a force is applied to a mass
For every action there is an equal and opposite reaction
