Heisenberg's Uncertainty Principle

Heisenberg has a book that name is The Representation of Nature in Contemporary Physics. Heisenberg describes the quantum physics innovations brought about by understanding nature and the universe, based on his uncertainty principle in this book. The book does not contain theoretical confusion and it focuses on 'meaning'. Therefore, I think it has become more attractive.

So let's talk about the uncertainty principle that frequently repeated. The Uncertainty Principle says that we can not accurately measure the momentum hence the speed and position of an electron. There is some uncertainty in the measurement of both quantities and the multiplication of these uncertainties has a minimum value. For example, if you want to determine the position correctly, the uncertainty in the momentum approaches forever. Of course, the opposite is also true. Well, where does this come from?

To see any substance, a light must go to it and the light must come from there to our eyes. Light has both wave and particle properties and we need to use a short wavelength light to reduce the uncertainty of the position of the electron during this observation. However, short wavelength refers to a relatively high energy and this means that when light strikes the electron it will seriously affect its momentum and cause some uncertainty.

Electro Magnetic Spectrum

I aware that so far was a little boring but it is very interesting from here. You could ask that does all this mean, what brings us? In fact, all of this means that as an observer, our knowledge of an electron is limited and we can not access all of the information about it. The same thing is true for macro sized objects that we can see in the environment but their masses are so large that they cause them to be hardly affected by the photons that hit them. For example, how much a photon striking a moving truck can change its momentum? But the same thing is not the case for very small particles such as electrons, it has now descended to levels comparable with photon. When we send a photon to examine such a system, the system will be broken down by the effect of photon, so the system that we have examined from now on will be our effective system, not our basic system. It is no longer an independent, objective nature that is observable, but a nature that comes into contact with us. The mathematical formulas we find are not the formulas of nature, but the formulas of nature that jump to us.

I guess it's a bit weird and jarring.
