Document Summary
Electron being represented by wave function in nature two distinct probability functions superposition of states cannot find electron. Box with cat and radioactive material- probability that it will decay is 1/2. When it finishes enables hammer to hit a gong which releases gas and kills cat. How do we know if cat is dead or live. But schrodinger claims it is ridiculous to apply quantum mechanics (with superposition of states some ppl claim it is in a superposition of state- one half dead, one half alive and indeterminism) to macro world (determinism) No scientific theory that est at what scale you have quantum and what is macro. Einstein formulated rules of general and special relativity special relativity claims nothing can go faster than the speed of light. Quantum field theory makes quantum mechanics relativistic by removing all observables-spin, etc. clear contradiction between our understanding of determinism and finiteness of nature that is being challenged.
