Probability and unbiased events?

This question is only for the enlightened ones!


Can we truly have an unbiased event? All events which we call as unbiased are so because we cannot, at this stage, account for all the forces affecting the outcome. For example, tossing a coin or rolling a dice is not an unbiased event as the outcome for the same can be predicted if we know all the intial conditions and the forces acting on coin/dice. So can we really have an unbiased event? Some long ago told me that it happens in the world of quantum mechanics, but I am not sure. Can someone throw some light on it?

Probability and unbiased events?
Yes, physicist currently believe it is impossible to know both the direction an electron is traveling and its speed.(Heisenberg Uncertainty Priciple) This is, imho, the major short coming of String Theory, It accepts that everthing is just probability. It may be true, that the probabilities are close, but in generations to come they hopefully will be able to refine it even more.
Reply:The possibility does exist, the probability is very low. Bias can be construed from just about anything including air pressure, etc. If something occured in a complete vacuum such as quantum , the possibility would be greater but human hands and minds couldnt touch it so the probablity is still very low.

If the laws of physics are truly constant from place to place and from moment to moment then theoretically you could throw the dice in precisely the same way repeatedly (same orientation in space, thrown at the same angle, at exactly the same speed, etc.) and produce the same results. But to do that perfectly it might require that every atom in the room start out precisely as it was at the beginning of the previous throws. Good luck with that.





There are a lot of variables and a small change in any of them can produce different outcomes. In reality there are substantial differences in several variables making the outcomes unpredictable.





It would be interesting to do an experiment where you try to replicate results by placing a die in an automated thrower and attempt to replicate results.
Reply:Show me the bias on the probability for a radioactive atom to decay.





Thanks for stopping by.
