Just to be somewhat controversial:

I really think Einstein's comments about his refusal to believe God plays dice was perhaps his worst moment. Its a completely unscientific statement. However it shows that even the greatest scientists are prone to the sort of bias or pre-conceived ideas suffered by humans. If we deconstruct what Einstein is saying it makes some ridiculous assumptions:

Who or what does he mean by God? Its not enough to say he just meant the universe - which is what his apologists usually claim. He is implying that something or a God designed the universe with a purpose in mind. And that something had a choice. Its inescapable no matter how you interpret his statement that he must have believed there was some methodology or consistent idea of how the universe should be at the point of creation.

I find the fact that people still use his statement as some sort of argument for Determinsim rather silly when had that statement emanated from anyone else it would have been flatly rejected as dubious speculation.

Now Im not trying to goad Einstein fanatics but just pointing out that his insistence on Determinsim was deeply flawed from any logical perspective. That doesnt take away from his brilliant work on GR one iota.
