Summary of Catastrophe Theory

Origin: Developed by French mathematician Rene Thom in the 1960s.
Focus: Studies sudden shifts in behavior due to small changes in circumstances.
Classification: Catastrophes are bifurcations between different equilibria.

Multiple Choice Questions

All possible outcomes of a quantum event occur in separate, parallel universes.

Quantum particles follow deterministic paths but are not observable.

Quantum events are influenced by macroscopic observers.

Quantum particles can only exist in two distinct states at any given time.
