Summary - II
- Two Slit experiment:
- Interference depends upon the possibility that each particle went through either slit
- If one detects which slit a particle went through, the interference disappears!
- Thus the observer is involved. The act of observation affects the outcome!
- Schrodinger's Cat Parable:
- Is the cat definitely either dead or alive BEFORE the box is opened?
- Bell’s proof shows one of Einstein’s ideas was NOT correct
- Each particle does not have objective reality!
- It’s properties are affected by measurement on another particle (far away!) It is not “dead” or “alive” until the “box is opened”!
