Study Notes

Intellectual Revolution

Refers to Greek speculation about nature from 600 to 400 BCE, prior to Socrates.
Terms associated with this period: pre-Socratic, non-theological, or first philosophy.
Characteristics include:
- The belief that the world is a natural whole, not a supernatural construct.
- Natural laws should be followed as ignoring them is considered immoral.
- Intellectual individuals played a key role in discovering these natural laws.

Scientific Endeavors

Humans have engaged in scientific efforts to understand nature and its workings.
Research into the physical and natural worlds has yielded significant shifts in society.
Ongoing discoveries continue to impact technology, space exploration, and environmental issues.
Major acceleration in scientific acquisition began with the Scientific Revolution in the 16th and 17th centuries.

Copernican Revolution

The geocentric model, proposed by Ptolemy in 140 AD, posited that the Earth was at the center of the universe with circular orbits of celestial bodies.
This model struggled to explain irregularities in planetary motion, such as retrograde motion.
Plato noted differences in motion laws between celestial bodies and terrestrial objects.
Nicolaus Copernicus proposed the heliocentric model, suggesting that planets orbited the sun, addressing inconsistencies of the geocentric model.
Copernicus delayed publishing his ideas for thirty years due to fear of religious backlash, eventually releasing On the Revolutions of the Celestial Spheres shortly before his death.

Galileo Galilei

Galileo utilized the telescope to provide evidence supporting the Copernican model.
Observed phases of Venus and Jupiter's moons, disproving the idea that all celestial objects orbited the Earth.
Faced persecution and was forced to renounce his support for heliocentrism, spending the remainder of his life under house arrest.

Johannes Kepler

Formulated three laws of planetary motion:
- Planets move in elliptical orbits with the Sun at one focus.
- The time to travel any arc of a planetary orbit is proportional to the area of sector between the central body and that arc.
- The relationship between the squares of the planets’ periodic times and the cubes of the radii of their orbits.
Kepler viewed his findings as celestial harmonies reflecting divine design, paving the way for Isaac Newton's later mathematical principles of gravity.
Together, Kepler and Newton’s work transformed the Copernican heliocentric theory into a dynamic model of the universe.
