Saying something is "uncertain" is not an answer to any question. Saying something has a point origin at an event horizon, at least makes an attempt at a definitive answer. You might not like the "observer" explanation, but it is a more rigorous definition of reality. "Limitation of what we can know," vs "limitation of what we can measure" is just semantics. It is the same thing.

scuh a beatiful explanation! Thank you

Thanks for the excellent presentation. Another analogy for the Heisenberg Uncertainty Principle I like to use is detecting audio at different frequencies. You can easily detect the start and stop of a high-pitch noise, light the "high-hat" sound in dance music. Low-frequency tones (20-30Hz) are so spread out that it's far more difficult to tell where they start in time. In typical music, a bass thud is really a short high-pitch impulse followed by the long bass note to give the listener a better sense of when the "beat" starts. Keep up the great videos!

@jayvaibhawverma

Жыл бұрын

Nice. That's a good analogy. But aren't the low frequency tones generally pressure waves? Or more correctly, sound vibrations are pressure waves. So, can we consider the Energy-time equation of the Heisenberg's Uncertainty to deduce the analogy you have given? Because I think that Position-momentum uncertainty will become vague for understanding this. What do you think?

There are no such people, unless they can make an infinite number of clones of themselves. :-)

It should be noted, decoherence is often quoted as a solution to why we never see quantum behavior on macroscopic scales, but this isn't the full story. Decoherence is just a term used to describe what happens when a huge quantum system's many parts interact, both with each other and with their environment. Everything gets scrambled up, and the system's parts begin to behave according to classical probability rules instead of the Born rule. What this does model is the emergence of classical statistical mechanics. But there is no mechanism that decoherence provides that explains the quantum measurement problem. As a system begins to interact with its environment, the state of the system, at least in principle, remains stuck is a massive entangled superposition, all the way to the macroscopic level. Interactions by themselves do nothing, according to Schrödinger's equation, to force a system to leave a superposition of states. This only appears to happen (for some reason) once the system interacts with measurement devices. Therefore, it's still an interpretive question, and an unanswered one at that, to ask what the state of the system at large scales.

This was the best explanation of the double slit experiment I have ever seen - which really helps drive home quantum phenomena

@schmetterling4477

Except that the double slit is not a quantum phenomenon. A quantum phenomenon either has Planck's constant in it somewhere or it requires multi-quantum correlations like entanglement. ;-)

What a great, intuitive explanation of why we don't see quantum behavior at our macro level. How is it that after watching dozens of other videos from various creators about the quantum world, this is the first time I've understood the quantum/macro relationship?

As always, Awesome video Arvin! By the way, I was thinking what would the animation look like when you put a photon detector on the double slit experiment? Like then we’d be able to see the ball coming out off the ball throwing machine and going thru the slit in two straight lines but still creating the interference pattern? Also for fingers thru glass containing water, I don’t think thats photon demonstrating quantum behavior , thats merely total internal reflection, but I admit it’s a good analogy for Quantum tunneling

AWESOME VID

I'm 40, wish this content was available when I was 14. Great work, videos keep getting better - huge fan.

I followed the link for the FTIR and I’m trying to understand it. How about a video on this phenomenon? Love your videos!

Arvin, what a didactically amazing idea!!! I've never seen anything like this before, and such an animation is immensely instructive for looking at the unintuitive wave properties! A tiny nitpick, at 5:50, about the uncertainty principle (UP), it would have been better to say more unambiguously that the UP had been _estimated_ by Heisenberg and _derived_ a few years later; it's simply the Schwarz inequality between conjugate uncertainties in the position and momentum spaces, related by FT-but you know it, whom I'm talking to! I personally know that many physics enthusiasts who try to wrap their heads around QM believe the inequality has been _postulated_ axiomatically, like, for example, the Born rule has. Possibly, the persistent imprecise wording is due to the fact that Heisenberg didn't derive the formula later named after him, as the Stigler's law (formulated and named after Stigler by Merton, naturally) predicts. He only used an order of mag estimation. Too bad we use imprecise “principle,” “rule,” “postulate” etc. in physics. QM is sheer math, with its complex-valued operators and infinite-dimensional state spaces corresponding to nothing in Nature, that, IMO, it would be less confusing-assuming generously that QM _could be_ less confusing-to use “theorems” and “axioms,” as mathematicians do. “Heisenberg's theorem,” “Born's axiom;” no ambiguity :) Owning a 5-string bass guitar with an added low B2 string (~125 Hz), I often use it as an example: if the player slides his finger up or down a semitone, changing the length and thus resonant frequency on this slow-vibrating string, how much time does one need to recover a new note-i.e, the change in frequency? The answer is derived (with a few technical assumptions) with FT and the same bounding inequality on the time and frequency domain uncertainties: exactly 1/4 of the period. It's a warm-up math before the full UP derivation. :)

In the last month or so, I have seen quite a lot of videos on similar topics to this, of which three have been outstanding. Those three include this one.

Many thanks teacher

Woww you brilliant.. 🎉

Re the uncertainty principle: I think that's actually one of the least "weird" properties of "quantum world". Because it's simply an inherent property of all waves, not just the wave function. For example, you can observe a very similar thing with sound: you may have a nice tone, which is a sinusoid wave---so you can easily measure its frequency (wavelength) and that's what defines the pitch. But you can't locate a tone to a singular moment---only to an interval in time during which it sounded. On the other hand, a clap or a gunshot is easily pinned to a moment, but you can't really say what's its pitch; as it's just one sound pressure peak, there's no frequency to it... Same thing.

Thank you so much and beautifully done! Making the non intuitive and hard to believe awkwardness of quantum mechanics visible!!!! 👍👍👍😃

Really enjoyed the video and the tunneling explanation. Would've loved to see mention of De Broglie's hypothesis/equation. For me personally, it really solidified the idea that these subatomic particles aren't bound to "particle-like" behavior.

I really wish educators were held to a much much higher standard (& compensated as such). Imagine a generation of people, 80+% of which being educated by people somewhere near Arvin's level.

I have never been so excited and confused watching KZread video

Very nice explanation of where the understandings end and theories of gobbledygook begin. 🙃

I'm not done yet with the video, but let me tell you, I've been watching stuff about that uncertainty thing.

I have a great curiosity from longtime to know about your qualification I mean in which field of physics you studied so that you motivated to make such amazing and elaborate explanations even though professors don't gave such explanations ;if you interested pls replay...

Thanks (again) Arvin for this video. I always wondered why the double slit experiment doesn't work for large objects, but is does for electrons, while electrons do also interfere with their surrounding. Of course an electron is much smaller than a tennis ball, but is has a charge and mass and even the smallest interaction should prevent an object (electron) to come in superposition. But now I understand that if an object is not a pure wave function because it exists of many waves that are not in sync, it can not be in superposition.

@ArvinAsh

An electron is a single wave, and so behaves like a single wave. A grain of sand is trillions of waves that interfere with each other. It no longer behaves like a wave overall.
