But QM uses statistical methods as main tool and has invented the 'uncertainty principle', to express the impossibility to do, what you believe they actually can. Actually QM can NOT predict the path of an individual particle or atom. One reason: particles are not individuals. IOW: you cannot number particles and find the same particle under the same number again. And if you do and try to confine the realm of investigation to a specific particle, the uncertainty principle comes into play. > No. I want to express, that the input into a system, which we try to > model, is not known completely. > > This is so, because we have only access to a subset of all influences, > that have an impact on the outcome of something. If you take a certain spot and calculate, to which form all influences onto this point would overlap in the future, you would obviously need to estimate all possible influences. Only you cannot do this, since only a subset of what is possible in principle is known and could be measured. But e.g. neutrinos are hard to measure, but may eventually have an impact. So you are obliged to restrict the model to simple cases, where most of the influences are known and under control. Only this is not, what we usually want to measure and what predictions are about. Predictions are from the realm, we have interest in and that is our usual scale in the macroscopic range. But macroscopic systems contain really large amounts of smaller items and these small entities are actually, what drives the process, we try to model. The overall shape is of no particular interest (for these small items) since they simply to not know. So we want to predict, what is actually generated by statistical processes. And that will not work. TH
