I don’t normally comment on KZread videos but I have to say this is an EXCELLENT video. You not only explain a very interesting effect that’s not often discussed but you also explain ancillary topics succinctly like gauge invariance, curl, line integrals etc. You’re using just the right level of mathematics to make it easily approachable to individuals with a college level of education without resorting to leaps due to having to dumb it down. Really an Incredible job. Please pick any topics for future videos and go at it! Looking forward to it.

Omggg!! This channel taught me alott just under 26 mins, Please Do Explain the Schrödinger's equation in one of your next videos 🙏✨️ All the best ❤️✨️

Glad to hear that! Schrödinger equation is coming up in the next 2-3 videos😃

I got a master's in physics in '99 and actually teach high school physics. You have cleared some things up for me that I didn't understand for many years. Thank you.

It's almost like the lesson here is that you can't really enclose a magnetic field, so saying it was a closed magnetic field was wrong in the first place.

Honestly.. I have a question.. Won't that circle containing magnetic field affect the trajectories of electrons and mess with them through the double slit and maybe change the result too? Just curious. They don't seem to do so in the experiment. And also, it's amazing how Vector potentials do actually exists 👍 It's an amazing concept!! Please keep making more videos sir, I love your channel 🫶

Thanks for the support💚 And yes, you are right. The circle/enclosure, which is there to keep the magnetic field confined will interact with the incoming electron. However, that is not a problem. In the first run of the experiment, we still have the circle, it’s just that the magnetic field is off. In the second run, we turn on the magnetic field and the circle is ofc present. So whatever effect the circle has on the experiment is present in both trials. In essence, we are comparing the result of having “double slit+circle” vs “double slit+circle+magnetic field”.

bruh the music 😂

Thank you for creating this video. I would welcome a video explaining the Schrödinger equation and demonstrating how it can be used to calculate the amplitudes of various eigenstates of a system such ammonia.

Sure thing! I'll schedule that as one of the next videos. Btw, Ammonia??

First off, a rather good overall explanation of this "paradox", a very clear discussion of the equations used, and excellent graphics (You can talk a bit faster, however ;) ). I'll simply add that the math really say's nothing about the 'A' field for any specific region (or enclosed by the line integral) except giving its total value. As you point out, the double slit electron experiment, certainly does prove that the vector potential cannot be zero in any region outside the enclosed/shielded 'B' field area. While Maxwell's equation for this situation doesn't account for this behavior (not too surprising since magnetic fields are just uncorrected electric fields in motion) it is obvious that this is where the error dwells. Certainly, this demonstrates a topic the two theoretical approaches provide rather dramatically different results.

Thanks! And yes, certainly, the AB effect exemplifies a bunch of physical principles at play. Another interesting discussion is that regarding the connection between Berry phase and the Aharonov-Bohm effect. This effect can also be approached in a different way: by analyzing the accumulated Berry phase as the wavefunction travels from the slits to the screen.

Great video, but for the music. Perhaps on picking the premises without great care you created the strange effect, much like a Zeno's paradox.

It's said determin and rhymes with in, despite ending in mine and seeming like it should be said as it is written. That said, no one who understands this video was confused by your pronunciation.

It seems to me that it would be worthwhile to substantiate the applicability of Stokes’ theorem

@@WorldofQuantum6.62e-34 Yes, I understand that all the necessary theory for a completely strict description will not fit even into a 3-hour video. It’s just that in this case, the statement of the problem “there is a magnetic field in this region, but in another region it is not” hints at the discontinuity of the magnetic field and therefore, in my opinion, it is still worthwhile to discuss in more detail the application of Stokes’ theorem. However, it's up to you to decide, overall the video is very good.

Can magnetic shielding ever be complete?

As fas as I know you cant shield it

I have a problem with the double slit experiment. A laser in ONE hole makes interference pattern. WHY? Don't believe me? Google "laser interference pattern" Now in ONE hole can make interference pattern im sure 2 can a in interference pattern. So please tell my the double slit experiment is true if ONE HOLE can do the same?

With luck and more power for you.

Great video! I had never heard of the effect until now and now I am very intrigued!

the musics too disruptive

the whole reason to even have quantum mechanics is that humanity put too much value into cause and effect

You do not show what happens . You just talk about it. One of the worst most frustrating youtube ever.

great video, but why so much mispronouncing?
