Study Notes
History and Development of Physics
- Physics originates from the Latin word "physica" and the Greek term "phusikḗ," meaning "study of nature."
- Ancient civilizations like the Sumerians, ancient Egyptians, and the Indus Valley Civilisation had predictive knowledge and a basic understanding of the motions of celestial bodies.
- Western astronomy's origins can be traced back to Mesopotamia, and Western efforts in exact sciences are descended from late Babylonian astronomy.
- Early Greek philosophers rejected non-naturalistic explanations for natural phenomena and proposed ideas verified by reason and observation.
- The fall of the Western Roman Empire led to a decline in intellectual pursuits in Western Europe, while the Eastern Roman Empire continued to advance various fields of learning, including physics.
- John Philoponus, a Byzantine scholar, questioned Aristotle's teaching of physics and introduced the theory of impetus.
- Philoponus' criticism of Aristotelian principles of physics served as an inspiration for Galileo Galilei during the Scientific Revolution.
- In the 1300s, Jean Buridan developed the concept of impetus, a step toward modern ideas of inertia and momentum.
- Islamic scholarship inherited Aristotelian physics from the Greeks and developed it further during the Islamic Golden Age, emphasizing observation and a priori reasoning.
- Aristotle's principles of physics were criticized, but it is important to identify the evidence on which he based his views.
- Aristotle's science formed the backbone of the science taught in schools today, and his findings are still taught in science classes.
- Aristotle believed that each element had its own natural place based on its density, and when a small amount of one element enters the natural place of another, the less abundant element will automatically go into its own natural place.
