Is uncertainity a postulate? [duplicate]

I heard the standard interpretation of Heisenberg Uncertainty Principle: Just the measurement affects the position of the body because always you want to see a body (=to measure the position), you ...

Is uncertainty principle a technical difficulty in measurement? [duplicate]

Is the uncertainty principle a technical difficulty in measurement or is it an intrinsic concept in quantum mechanics irrelevant of any measurement? Everyone knows the thought experiment of measuring ...

Heisenberg's Uncertainty Principle - Humans knowing vs values existing in nature [duplicate]

Heisenberg's Uncertainty Principle states that the more precisely the position of some particle is determined, the less precisely its momentum can be known, and vice versa. What I am getting out of ...

Is the uncertainity principle a practical reality, a theoretical law or a measurement problem? [duplicate]

I understand we cannot state with arbitrary precision the position and momentum of a micro-particle as we superpose infinite waves to create a wave packet at the exact position of the particle and ...

Uncertainty principle implies the non-deterministic universe? [duplicate]

Does the uncertainty principle imply the non-deterministic universe, or just the fact that our model of the universe, the one based on observation, can be at most non-deterministic, since we will not ...

Why is the camera not the culprit? [duplicate]

Perhaps I am completely wrong, but as I understand it our observation of a system can affect the outcome. The example I remember is the double slit experiment where electrons behave as a wave at ...

What does the Heisenberg principle actually mean? [duplicate]

As far as I can understand, the Heisenberg principle limits the possibility of calculating the exact position and momentum of electrons, as the light we use to observe it changes it's velocity. But ...

Is the Heisenberg uncertainty principle based on experimental imprecision in measurement? [duplicate]

As far as I understand, the Heisenberg uncertainty principle states that the more one of the conjugate quantities are known, the less the other is known. So for instance, if the velocity of a particle ...

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 ...

If we solved the observer effect/problem, doesn't this mean Quantum superposition isn't actually real? [duplicate]

I am nowhere close to a physicist so please correct me anywhere I am wrong From what I understand about the observer effect, when we measure one intrinsic property of an electron such as position, ...

Why does heisenberg uncertainty principle work? [duplicate]

Hiesenberg's Uncertainty Principle states that inaccuracy in momentum and position will always be there and we will never ever be able to get it 100% accurate. Suppose in future millions of years from ...

Is the uncertainty principle a property of elementary particles or a result of our measurement tools?

In many physics divulgation books I've read, this seems to be a commonly accepted point of view (I'm making this quote up, as I don't remember the exact words, but this should give you an idea): ...

Uncertainty in Uncertainty?

I was reading about how the Planck's Constant can be measured with LEDs, which made me think about this question. The Heisenberg Uncertainty Principle states that: $$\Delta x \Delta p \ge {\hbar\...
