Developments in the Sciences: The Emergence of a New Physics
- a. Belief: based on hard facts and cold reason, science offered certainty of belief in orderliness of nature that appealed to religion-less people
- b. Belief: applying scientif laws would enable complete understanding of physical world and reality
- i. Physics corrected this belief
- a. 19th: westerners adhered to mechanical conception of universe postulated by classical physics of Newton
- i. Giant machine in which time, space and matter were objective realities that existed independently of the people observing them
- ii. Matter was made of indivisible solid material bodies called atoms
- a. Views were questioned at end of 19th
- i. Marie Curie and Pierre discovered that radium gave off rays of radiation from within the atom itself
- 1. Atoms not hard, material bodies, but small worlds containing electrons and protons that behaved randomly
- i. Max Planck rejected belief that a heated body radiates energy in a steady stream but said that energy is radiated discontinuously, in irregular packets called “quanta”
