Study Notes

Introduction to Philosophy of Physics

Philosophy of Physics: Studies assumptions and foundations of physical theories, exploring the nature of space, time, matter, and limitations of physical knowledge.
Provides insights into reality and identifies limits of scientific theories.

Key Concepts and Debates

Determinism vs. Indeterminism
- Determinism: Future conditions determined by current states (illustrated by classical mechanics).
- Indeterminism: Acknowledges that not all events are predetermined, as evidenced in quantum mechanics.
Realism vs. Anti-Realism
- Realism: Belief that physical theories represent reality accurately.
- Anti-Realism: Theories are seen as tools for making predictions rather than true descriptors of reality.

Class Exercise

Schrödinger's Cat Thought Experiment
- Scenario presents a cat that can be both alive and dead, highlighting quantum superposition.
- Task involves students discussing their views on the cat's dual state and its implications for reality.

Class Discussion

Discuss the impacts of the Schrödinger's Cat experiment on perceptions of physical reality and the act of measurement.
