- Thats why I said "As far as it is possible to test for randomness,".
-
- A polarized photon has 50% chance of going through a 45 degree polarization
- filter. Unlike an atom nucleus, photons have no observable parts that can keep
- local variables, or as you call it:"beneath the level of the event".
-
- It is alway possible to make physical theories without randomness, but those
- theories still possible to make, are becoming more and more messy.
-
- Good bye, Determinsm.
