Scientific Revolution Flashcards
Francis Bacon
Proficience of Learning
Homocentric
earth is at the centre of the universe
Heliocentric
sun is at the centre of the universe
Empiricism
knowledge can only come about by experience
What were the two dominant ideas during the scientific revolution?
- Aristotle’s approach of empiricism
- Plato’s ideas of theories to explain the natural world
What are Kepler’s three laws of Planetary Motion?
- Planets travel in eliptical circles
- Planets to not travel at a constant speed
- The further from the sun, the longer it takes to orbit it
Kepler
Astronomia Nova, 1609
Kepler - increasing scepticism
- Encouraging people to look for natural causes and observe events, rather than jumping to conclusions and using magic as explanation
- His model of the solar system and planetary laws developed understanding of the universe
- Later scientists were able to build on his work
Kepler - no change
- Witchcraft act not repealed until 1736
- Still widespread popular belief in witches
- Members of the Royal Society still believe in witchcraft
- He was deeply religious
Galilei
Dialogue Concerning the Two Chief World Systems, 1632
What did Gelilei write about in his 1632 publication?
- He believed with Copernicus that the sun was the centre of the solar system (Heliocentric)
- The book was structured as a debate between three men with conflicting views
Galilei - Increasing scepticism
- His work was published in Italian and translated into a number of other languages, ensuring his influence became widespread
- He begins the idea that the church and state should be separate
- His biggest influence was in ensuring a mathematical approach to natural phenomena
- Chruch saw him as a threat - arrested and books banned
Galilei - no change
- Widespread popular belief in witches e.g.Salem in 1692
- His understandings were not supported by elites e.g.Church condemns him in 1633
Newton
Principia Mathematica, 1687
What ideas were put forward in Principia Mathematica?
- Kepler’s laws of planetary motion were proven mathematically
- That physics on earth worked the same as physics in the rest of the universe
- Explained centrifugal fore
- Developed a theory of acoustics
What were Newton’s three laws?
- Every object will remain in place or in motion unless acted upon by an outsider force
- The external force on an object is equal to the mass of the object times its rate of acceleration
- For every force, there is an equal and opposite reaction
