A cop pulls over a physicist and asks, “Sir, do you know how fast you were going?”
The physicist replies, “No, but I know exactly where I am.”

I think of a camera shutter speed as an analogy for this

Slower shutter speed gives momentum

Faster shutter speed gives position

This is extremely helpful! I’m currently taking Quantum Theory at an undergraduate level and this helped me solidify my understanding

[Rastlov]

Thank you! I finally understand why you can't calculate the position and momentum. Sometimes less is more.

Physics professor- "Where is your homework?"
Student- "Well, I've calculated it's velocity with such precision that it could be anywhere in the universe"

As an electrical engineer who doesn’t have a quantum physics background, but a strong mathematical background and a strong background in signal analysis, this explanation made complete sense and I’ve never heard a better explanation for myself.

What would really help to understand the uncertainty principle is by working out an example mathematically. Take for example the wave function of a 1s electron and apply commutation to it, specifically the [A, B]- commutation, where A is the kinetic energy operator and B is the location operator. This would result in the following: (AB - BA) • WF, where WF is the wave function. This equation basically tells us what the difference in expectation value is if we first calculated kinetic energy and location (A•B), and then the other way around (B•A). Logic would tell us that the difference would be zero as the order of measuring shouldn’t matter, but you’ll see on the contrary the uncertainty factor as a result of that equation, meaning that the order in which you calculate the expectation value is off by the uncertainty factor. Hope this helps!

I like the use of a spring to represent a sine wave, it catches it's rotation aspect...
What would happen if we rotated a polarizer at the same frequency as light, can the spring be unwound?

You are truly amazing on explaining this hard concept on YT (one of my favorite!!) can you do another short to explain the principle with the relation with energy and time? Thank you anyway for this excellent short 👍

To observers agnostic of each other take the measurements and then meet up with each other and compare results. You now know the position and the momentum.

[ENetArch]

A simpler explanation. Is to compare a ping pong ball hitting a bowling ball and trying to determine position and speed of both, using one or yhe other.

[MINRITY-REPRT]

You just said the magic word - "probability". Humans are too slow and too large to see an electron and determine where it is. The entire field of "quantum mechanics" is just that - a mathematical system of statistical probability. But the words "quantum mechanics" sound so much more mysterious....

[rhouser]

Kinda like you can know all the words said but not understand anything that was said..

[vibhutisrivastava]

Wow! Mom I know the universe it's just uncertainty of electrons

[michaelhester]

There could be only one electron in the entire universe

[EmpressOfExile]

I thought all we had to do is "observe" the electron and that would eliminate the uncertainty? 🤔

[Fran-orlt]

Give me a surfboard and i will certainly find your wave.

[danmiller]

Whose idea was the lefthanded cntrclkwz wave? If you think of it has a corkscrew you can see this. I bet no one noticed. Physicists seem not to pay attention to this. In fact they dismiss lefthanded helicity and say it's "frame dependent" and only appears from a moving frame.

[adamdymke]

Yeah, it basically boils down to the fact that a wave can't be both thin and wide at the same time.

[bmilano]

What led to this question real quick?😅
