Scientific Revolution Flashcards
Main Idea
mid 1500s, scientists began to question accepted beliefs and make new theories based on experimentation
Relevance
Scientists questioning led to development of today’s scientific method
Common sense
Make assumptions based on non-scientific observations; in use by most of society in medieval times
What theory was originally accepted? Who backed it?
The Geocentric theory. The church.
Geocentric theory
Sun (and universe) revolves around earth (decided thru common sense.)
Who developed and expanded the geocentric theory?
Aristotle in 4th c BCE, Ptolemy in 2nd century CE
Scientific Revolution
1550-1700 CE; new way of thinking about natural world based on careful observation and a willingness to question accepted beliefs
What caused the Scientific Revolution?
European scholars and explorers and the printing press
How did scholarly works cause the Scientific Revolution?
European scholars translated many scientific works by Muslim scholars and uncovered many classical works from the Renaissance.
How did European explorers traveling to new lands cause the Scientific Revolution?
Needed better navigational instruments and measurements to travel to new lands?
How did the printing press cause the Scientific Revolution?
Helped spread knowledge and challenging ideas
Who developed the heliocentric theory? Who contributed? How so?
Nicolaus Copernicus. Tycho Brahe recorded planetary movements and reasoned that Copernicus was correct. Johannes Kepler mathematically demonstrated Copernicus’s correctness.
What additional discovery did Kepler make?
The elliptical orbit of planets around the sun.
What was the belief that the universe was limited to?
The solar system
Heliocentric theory
universe (solar system) revolves around sun (mostly correct)
What did the geocentric theory believe about the movement of the Earth?
At the center=no movement whatsoever
What did Galileo build that assisted his discoveries?
His own telescope
What did Galileo disprove? (Bit of an unfair q)
Number of accepted Aristotelian theories
What did Galileo discover with his telescope?
Sunspots, craters on our moon, four moons of Jupiter, phases of Venus
Did Galileo invent the telescope?
No (improved it.)
What did Galileo’s discovery of Jupiter’s moons prove?
Not everything orbits the Earth (they orbit Jupiter, so there are spheres in space that orbit other things.)
What did Galileo’s discovery of the phases of Venus (like the moon’s) mean?
The sun was the stabilized sphere in the universe (solar system) or else there would be no phases on Venus.
Why did the heliocentric theory scare Europeans so much?
church teachings were the basis of many beliefs in Europe. If they’re wrong about this, what else?
