Study Notes

Heliocentric vs. Geocentric Models

Geocentric Model: Earth-centered theory, where Earth is considered the center of the universe.
Heliocentric Model: Sun-centered theory, proposing that the sun is the center around which planets orbit.

Causes of the Scientific Revolution

Trade Expansion: Increased exchange of ideas and knowledge spurred scientific inquiry.
Study of Ancient Authorities: Reassessment of classical texts led to new discoveries.
Scientific Method: Development of systematic observation and experimentation transformed scientific practices.

Key Historical Figures

Ptolemy: Alexandrian astronomer known for the geocentric model; his theories dominated until the Renaissance.
Copernicus: Astronomer who formulated the heliocentric theory, challenging long-held beliefs.
Kepler: Discovered that planetary orbits are elliptical, with varying speeds depending on distance from the sun.
Galileo: Pioneered the use of the telescope in astronomy, establishing that celestial bodies are tangible objects.

Scientific Contributions

Newton: Developed the concept of the SI unit of force, contributing to physics and astronomy.
Cavendish: Authored "Observations upon Experimental Philosophy," advancing experimental science.
Descartes: French philosopher known for analytical geometry; linked algebra and geometry in revolutionary ways.
Bacon: Advocated for the scientific method, emphasizing empirical evidence and experimentation.

Philosophical Perspectives

Hobbes vs. Locke:
- Both philosophers agreed that people need to form societies out of a state of nature.
- Hobbes argued for an absolute monarchy for societal survival.
- Locke advocated for limited government, emphasizing individual rights and freedoms.
