Study Notes
Pre-17th Century Natural Philosophy
- Geocentric Model: Earth is the center of the universe, with celestial bodies orbiting it.
- Distinct Laws: Heavenly and earthly laws were believed to be different.
- Imperfect Earth: Earth is imperfect, leading to change and the process of potential becoming actual.
- Perfect Heavens: Heavens and stars are perfect and unchanging, moving in perfect circles made of a distinct material called "fifth essence."
- Young Earth: The age of the Earth was estimated to be only a few thousand years.
- Four Elements: All materials on Earth are composed of four elements: air, water, fire, and soil.
- Spontaneous Generation: Life was believed to arise spontaneously from non-living materials.
- Homogeneous Sunlight: Sunlight was described as white, pure, and homogeneous, composed of the same substance throughout.
- Integration of Science and Religion: The views of Aristotle were integrated with Christian ideology by medieval theologian Thomas Aquinas (1225-1274).
New Astronomy and Physics
- Precession of the Equinoxes: The gradual change in the position of stars over time challenged the idea of perfect circular motion.
- Seven Observed Planets: Ancient astronomers recognized seven planets: Mercury, Venus, Mars, Jupiter, Saturn, the sun, and the moon.
- Copernican Model: Nicolas Copernicus proposed a heliocentric model, suggesting that the planets, including Earth, revolve around the sun.
- Copernicus's Contributions: Copernicus excelled in analyzing astronomical observations and placed the sun at the center to clarify existing difficulties. He calculated the approximate distances between celestial bodies, revealing a larger universe than previously thought.
- Kepler's Laws: Johannes Kepler proposed that planets move in ellipses, not perfect circles, disproving the ancient belief in perfect circular motion.
- Bruno's Views: Giordano Bruno defended Copernicus's sun-centered theory and argued for an infinite universe with infinite worlds inhabited by intelligent beings.
- Galileo's Experiments: Galileo Galilei's experiments demonstrated that objects of different weights fall at the same rate, contradicting common observations.
- Telescope Observations: Using a telescope, Galileo discovered the mountainous and cratered surface of the moon, the moons of Jupiter, and the composition of the Milky Way as thousands of individual stars.
- Galileo's Trial: Galileo faced a trial for supporting Copernicus's theory and was forced to recant his findings.
- Bacon's Advocacy: Francis Bacon emphasized the importance of experimentation, observation, and collaborative scientific inquiry.
- Descartes's Method: Rene Descartes advocated for a skeptical approach to knowledge, doubting everything and starting fresh.
- Newton's Laws of Motion: Isaac Newton outlined three laws of motion:
- A body at rest or in uniform motion remains so unless acted upon by a force.
- A force can change the direction of a moving object.
- For every action, there is an equal and opposite reaction.
- Newton's Light Experiment: Newton demonstrated that sunlight is composed of different colors, a concept that explained the formation of rainbows.
