electron
Its position is unknown but the distance from the nucleus is

I have no idea. The only related things I vaguely comprehend are force particles and chaos theory. I don't think there's a layman's way to understand the models of the quantum structure of space-time. You can scream for a sound-bite explanation all you want, it's not going to make one appear. And it's not going to open up any more holes for you to cram the supernatural into, either. Quote:

I think that the misunderstanding here may be in what is considered to be randomness. We must acknowledge the difference between randomness on a macroscopic scale, and on a quantum level.
In the everyday, observable world many processes appear random because of the sheer number of outside influences affecting the outcome. For instance, consider a ball flying through the air. Simplistically, if we know exactly all the parameters of this system (mass of the ball, initial velocity, wind speed, etc.) we could, using simple Newtonian mechanics, predict the exact point at which this ball would hit the ground. However, many elements of this system cannot be determined exactly, or are changeable, e.g windspeed, so our prediction may be innaccurate. To counter this the obvious next step is to find out exactly what the windspeed will be at all times that the ball is in the air. But everyone who has gone out in a t-shirt because the met office said it would be sunny all day knows that this simply cannot be done. Weather systems are non-linear, and chaotic, and so may be affected by the smallest change in parameters (the famous butterfly flaps its wings and causes a tornado on the otherside of the world.) A similar argument applies to genetic mutation, it would be impossible for a geneticist to take into account every outside influence on a single strand of DNA over even a short period of time, never mind over the entire lifetime of an organism. Secondly, in the quantum realm randomness is not the result of not being able to map the whole system, or because the governing equations are non-linear. Schrodinger's equation, probably the most important in QM, is linear and quite simple, therefore, unlike in the everyday world, QM is deterministic and even an approximate knowledge of initial conditions should give accurate predictions for some time after. The randomness in quantum physics is an integral part of the theory, so you could say that it is caused by nothing, but it would be more accurate to say that this randomness is how the universe is. Of course QM has flaws and there are many theories being proposed to replace and we may see at sometime in the future a new dominant theory, which disposes of the idea altogether. Damn, this is the longest post I've ever made. |

I note that you have not in fact answered my question. Answering a question with more questions goes no where. I repeat again: How would you explore that fundamental nature of randomness in quantum mechanics? <taps fingers> |

If you take a many worlds QM interpretation then all of the possible interactions occur, problem solved
