Probability and unbiased events?

Question

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?

Editing to add reply to some of the answers:

1. Gebobs: We can't predict the bias because currently we are not sure of the nuclear forces acting. This should be predicatable later in my opinion.
2. Absynthia: Heisenberg's principle is more because of the interaction of photon rather than the non biased nature.
3. fancyname: Everything you mentioned was because of our lack of knowledge rather than the unbiased nature of event.

I am looking for a truly unbiased event in which there is NO possibility of knowing the outcome.

4. frugernity: To do that would be extremely difficult but not impossible!
5.kent j: Man they for sure are unpredictable but this one is a serious question.

Answer 1

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.

Answer 2

I get your drift.

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.

hi, it may in all probability help which you would be able to look into the main factors of quantum mechanics in slightly greater element. Heisenberg's uncertainty concept does not state that we gained't degree or are anticipating the interactions by way of a technical hassle. somewhat, it describes how accuracy in taking one length basically alters a gadget such that understanding yet another, appropriate sources accurately is impossible. to that end it extremely is basically impossible to degree a gadget in a manner that removes uncertainty. there is not any way previous this hassle; there are no via-rules of physics. So, there is not any thank you to describe a gadget in finished certainty; to that end, there is not any thank you to foretell a gadget's behaviour with finished certainty. although, the percentages of a undeniable experience happening in a undeniable volume of time -- that's, the risk of an experience -- could be accurately and constantly desperate. by the variety, on the same time as quantum unpredictability can basically take place with major frequency at subatomic scales, it does have a measureable effect on our macroscopic international. Schrödinger's Cat is a theory test that examines the ramification of huge scale activities (the existence or death of a cat) per quantum uncertainty-based activities like radioactive decay. And, even in environments we evaluate exceedingly deterministic (like billiard tables) we detect many, small, conflicting, turbulent forces that make it impossible to foretell, no count how intently it extremely is set up. So we in no way get remote from uncertainty. each and every thing is a roll of a loaded die.

Answer 4

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.

Answer 5

Show me the bias on the probability for a radioactive atom to decay.

Thanks for stopping by.

Answer 6

You have obviously never had a long term relationship with a woman.

Answer 7

I think that i have ab solutly no clue what the hell you are talking about
