### Is uncertainty uncertain?

I was thinking about uncertainty and wondered if uncertainty is inherently uncertain. I know in the uncertainty inequality for position and momentum, $\Delta x \Delta p \ge \hbar/2$, the presence of ...

### 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 ...

### 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 ...

### Does uncertainty principle truly represent the “lower bound” of the information we can obtained from a pair of noncommunicable operator?

Background I: Suppose the commonly used non commuting operator $\hat p$ and $\hat x$. The uncertainty principle told us that $\sigma_p\sigma_x\geq \frac{\hbar}{2}$. In standard quantum mechanic ...

### Why don't physicists interpret randomness in quantum mechanics as ignorance or limitations in our knowledge?

As the title says: why don't physicists interpret randomness in quantum mechanics as ignorance or limitations in our knowledge? Why is the randomness in quantum mechanics equations not added to the ...

### 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 ...

### 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, ...

### 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 ...

### 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 ...

### How can indeterminacy in quantum mechanics be derived from lack of ability to observe a cause?

I don't get this part of quantum mechanics. I get the part that you can't observe particles and not affect their behavior because you are shooting photons to them while you are observing them, but ...

### Uncertainty principle in macroscopic world

The uncertainty principle says that $\Delta x\Delta p\geq \frac{\hbar}{2}$. The uncertainty principle is to be viewed as a fundamental fact of nature herself, and the principle has nothing to do with ...

### Shouldn't the Uncertainty Principle be intuitively obvious, at least when talking about the position and momentum of an object?

Please forgive me if I'm wrong, as I have no formal physics training (apart from some in high school and personal reading), but there's something about Heisenberg's Uncertainty Principle that strikes ...
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\...
