Wunderbar, ein ungetrübtes Vergnügen für Menschen, die sich für die Realität interessieren und nicht für das Beobachten von Beobachtern. Wonderful, an undisturbed pleasure for people who are interested in reality - and not in observing observers.
Nice animation at the end, although I didn't quite understand it without an explicit representation of the measurement pointer, which is part of the system! So long as the measurement system is conceptually located in the world (the environment), you will have a measurement "problem".
It takes awhile to measure speed, but position is instantaneous. Just as time and frequency can't be known at the same time due to Fourier analysis, you can't measure speed and position at the same time due to speed being the time derivative of position. Heisenberg uncertainty has nothing to do with QM, even though many physicists believe it does! It's just the way measuring any derivative works. It can only be measured instantaneously in the limit as delta approaches zero. So there has to be a minimum delta in the physical world, and it is the very small value, Planck's constant.
@aikidlc I can't follow your explanation or question because it shows a deep lack of understanding of physics. If there is a question, please ask it clearly. If there is a statement of fact, please make it clear. Otherwise, thank you for your participation. I do understand that the basic concepts of physics can be difficult to understand without the proper mathematical and physical background.
