Study Notes
Physics
- Physics is the scientific study of matter, energy, and their interactions
- It covers subjects such as motion, force, heat, light, sound, and the structure of matter
- It's one of the oldest academic disciplines
- It was originally part of natural philosophy, but separated into a distinct research area during the 17th century Scientific Revolution
Key Developments
- Advances in physics led to inventions such as television, computers, and nuclear weapons
- The understanding of thermodynamics drove industrialization
- Mechanics directly influenced the development of calculus
Astronomy
- One of the oldest natural sciences.
- Early civilizations like the Sumerians, Egyptians, and Indus Valley Civilization had knowledge of the Sun, Moon, and stars.
- They used their observations for predictions and to understand celestial movements.
Origins of Western Astronomy
- Traces back to Mesopotamia.
- Egyptian astronomers left monuments reflecting their understanding of constellations and celestial movements.
- Homer, the Greek poet, mentioned celestial objects in his works.
- Greek astronomers named constellations visible from the Northern Hemisphere which are still used today.
Natural Philosophy
- Greek philosophers during the Archaic period rejected supernatural explanations for natural phenomena.
- They emphasized natural causes for events and sought explanations based on reason and observation.
- Many pre-Socratic philosophers, like Leucippus and Democritus, proposed ideas later proven correct through experimentation.
- Their hypotheses were tested using reason and observation.
Aristotle and Hellenistic Physics
- Aristotle, a student of Plato, wrote extensively on a wide range of subjects, including Physics.
- His work on physics was influential for over two millennia.
- Aristotle combined limited observation with logical deductive reasoning but did not rely on experimental verification.
- He explained motion and gravity using the theory of four elements: earth, water, air, and fire.
- Each element, according to him, had its natural place in the atmosphere depending on its density.
- He proposed that elements would revert to their natural places if displaced.
- For example, fire would rise to the top of the atmosphere, its natural place.
- One of his laws of motion was that heavier objects fall faster.
