Does Heisenberg's Uncertainty Principle describe real uncertainty or measured uncertainty?
Some derivations of Hesenberg's Uncertainty principle are based on the momentum of light or particles used in measuring an object's position and momentum. Does this lower limit on uncertainty describe ...

Is the uncertainty principle a statement about limits on our predictive rather than our measurement abilities?
Here's what I know. The Uncertainty Principle states that $$\sigma_x \cdot \sigma_p \geq {{\hbar} \over 2}$$
However, I also know that this principle refers to measurements performed over many ...

Problem understanding Heisenberg's uncertainty principle
Ok, I'm asking it, even in case of being closed and irrelevant.
It's about Heisenberg's uncertainty principle, and a very dualism of the way of information exchange in the software development world.
...

Uncertainty relation and instrumental errors
I was puzzled recently by what I've read in the internets about Heisenberg's uncertainty principle (one probably should never do this).
It claimed that in the usual relation
$$
\overline{(x-\...

Is uncertainty an emergent property of waves or only a statement about our measuring tools?
I am struggling to interpret the probabilistic nature of quantum mechanics and am wondering if uncertainty is an emergent property of nature or if this is really a statement about our measurement ...

Questioning the Uncertainty Principle [closed]
I am aware this is a widely accepted consensus within the scientific community now, however, majority opinion does not equate to truth as history shows. Furthermore, I still question the validity of ...

Does Heisenberg's uncertainty principle also apply to measuring velocity? Can we measure velocity at an exact time and point?
There will always be an error in measuring velocity because it is average velocity in some range of time not the exact time. So the physical quantity velocity doesn't exist at a moment. So how come ...

Heisenberg's Uncertainty Principle about electrons [closed]
According to Heisenberg's Uncertainty Principle when we shoot or project photons on an electron from one side then there is 100% possibility that there is some error in calculating the position and ...

Is it possible the quantum world to be actually deterministic after all? [closed]
Possible the "Heisenberg Uncertainty Principle" (HUP) describes the fact that we are not able to probe beyond a small size scale into the quantum world because the relative long light waves ...

h-bar limits measurement precision. What limit arises for h-bar itself?
The question is simple.
h-bar, or $\hbar$, limits the precision of every measurement, books tell us.
For example, length measurements are limited by the Compton wavelength.
What limit for the ...

Are quantum properties really indeterminate, or just unknowable?
Early on, it seems like Heisenberg's uncertainty principle was regarded as a principle of ignorance. That is, it says what's possible to measure or to know, rather than what actually is.
However, ...

Is uncertainty a physical obstacle? [duplicate]
Heisenberg's Uncertainty Principle states that you cannot know the position and the momentum of a particle at the same time (I believe this is the main idea behind it). And I have read in various ...

Quantum Mechanics - How do we know that the observed locations of electrons are random? [duplicate]
How do we know that the observed location of a electron (or any quantum object) is purely random (there is no way to predict it) within the probability-function instead of normal randomness (we don't ...

Quantum mechanics - "God does not play dice" - does he? Or might he not? [duplicate]
I'm a mechanical engineer by training, so please forgive ignorance in my question.
Heisenberg's uncertainty principle states (to my understanding) that one cannot measure both position and momentum ...
