Thanks to @lloydwatts60 for the design idea for the gears! Checkout his video with a wooden version and more insight into spin 1/2 (link in description)

Electron spin be like: Imagine a ball and it’s rotating except it’s not a ball and it’s not rotating

The thing of the belt actually caught me completely off guard!

Man electrons are like the USB port You put it straight don't fit flip it don't fit flip it again don't fit flip it again fits

The Stern-Gerlach-Experiment is my favourite physics experiment 😅 It was conducted by 2 germans in 1922 (Stern and Gerlach). They were actually about to give up the experiment, but then the Reichsbahn (german railway) cancelled their drive home from Frankfurt, so they gave it another shot at night. It was later found out that the experiment only worked because they smoked heavily inside the laboratory, which would be insane nowadays 😂 The smoke caused the screen to make the 2 dots visible.

Kudos to the people who walked around electrons to tell us about this.

This is my favorite action lab video. I have been thinking about electron spin for sometime now and have been showing my kids a slightly different version of 720° rotation using a plate that I hold in my hand. I rotate the plate palm up two full turns without dropping it and without twisting my arm off. The kids find it fascinating that one can do that kind of rotation.

It feels like the electron spin have some similarities to a *Mobius Strip* where you also need to complete 2 full "rotations" of the strip to return to the same side at the original position.

They are entertaining and educational at the same time...

Just plain awesome. As a fairly advanced scientist of 30+ years, I still always learn something refreshingly new and confounding from your videos. I love every one of them and your enthusiasm to match. I have no doubt you'll be making these for a long time to come. Thank you!... for serving us all.

The Belt trick is amazing like all of your explanations ❤

You make physics much more simple with easy world visuals. Thank you.

Basically he's NileRed but it's more physics. His voice is also extremely similar to NileRed and Brandon Farris.

Always making amazing content.

I love this channel... one of my best subscriptions by far!

3:45 It helps to say if you twist the belt 720 degrees clockwise you have to go under the book clockwise as well.

So nice to see and understand concepts about electrons.🙏😊

I love that you mentioned the The Stern-Gerlach experiment, and your insightful question and answers at the end! They were perfect follow up questions! Please continue to add questions and answers that reveal a deeper understanding to all your videos!❤❤❤👏🏽👏🏽👏🏽👏🏽

Thank you so much ! After many years looking for a way of understanding spin it is the first time I do. Not even in my native language.

These videos are always enlightening, but this one actually blew my mind at every turn! Very solid demonstrations and great editing. This is the kind of content I subscribed for.

Amazing expression!

That was a very well hidden jumpcut at 1:00! The talking over hides it so well

The first rotation was flawless but I saw slightly in the second one. Clever cinematography. I love how you always throw a trick in there or two. 😁

You are simply fantastic ! Thanks a lot for all the extremely creative videos you make.

Excellent video as always. I learn a lot from this channel. Thanks and kudos to you.

This was extremely interesting even tough I would love to have mote insight and background to better understand it

Very good illustrations. Thanks!

You would think if you have to spin an electron twice to get back to the initial state that just maybe 360 degrees for you and 360 degrees for the electron are not the same. Perhaps there are more or less dimensions that an electron interacts with and that is the cause of the strangeness. As in it would take an electron longer to rotate through 4 dimensions, versus your 3.

That was a really cool way to explain it ❤️ you should do more of this

I love this explanation on electron rotation topic

I enjoyed the editing SO MUCH!!!

To get the point you can play the "Antichamber" - a short (relatively) indie puzzle game . It has a lot of wierd perspective, spacial, non-flat topology stuff and etc. like impossible rooms and geometry.

I think that was a splendid explanation. Thanks for putting this on here.

Soo informative!. Thanks champ!!

Belt twist untwist is so cool!! And I understood it!! (May try it myself tonight!!)

Those are some clean jump cuts. Bravo!

1:09 was a jumpcut, but it was so seamless, I hardly noticed I wish video games loaded cutscenes and new maps like that

I really like your videos, everytime a unique concept.😍

Belt trick awesome Gears awesome explanation . Love you channel!

The t-shirt you wear being on point with the subject, love the details you put in your videos !

That was impressive as always. Thank u

Amaizing explaination bro.

Nice…. Truly creative ways of demonstrating the difficult to demonstrate

This is the best video so far explaining electron spin

Your videos are soooo awesome.......and really useful ..thank you sooo much for your videos we all love u alot..😊😊😊🥰🤩

Can you really walk around an electron if electrons don't ever sit still? 8:22 Can you show a drawing or animation about rotating apparatus and observing the wave function change?

thx m8... great information!!!

Very cool visual example

Many times when I watch this channel, I feel I just watched some magic illusion. Amazing!

This was one of you more complicated videos (for me as a layman) but with some background on magnetism (and the link with unpaired electrons in orbitals) the video is definitely comprehensible.

Thanks! We are studying HNMR (but from Morrison and Wade book, instead of Carey wich appeared in the video 😆) and we had to study spin and how it acts inside a magnetic field.

Most interesting video yet👍🏻😉😊

That cube animation, wow -))

Thank you so much sir

This is also called the Dirac belt trick. This Is a really nice demonstration!!

As usual the video is great! But the sponsor for this video has had a lot of controversies and scandals attatched to it. I hope you have looked at their background before telling your audience about them. Otherwise a great video!

book and belt trick blew my mind.

This was lovely

If there was any other classical example that described electron angular momentum better than the word “spin”, we would probably use that and call it something other than “spin”. But calling it “spin” is still close enough to what’s going on that we use it. But just keep in mind, it’s VERY different than just the idea that the electron is spinning.

the level of the topics is getting deeper and more interesting every time

Wow that is so amazing

By far, without a doubt, the best entry-level educational channel on KZfaq.

Just subscribed...great content...

A four-cycle engines valve timing does the same thing. Just like the four-cycle engine, the electron absorbs & releases engery from unseen particle-flow. The spin of an electron may be caused from smaller orbiting-particle systems moving around and into & out of the electron. It's always been my belief that orbiting-particle system's make up all matter, as well as all empty space, no exception to the rule. Thank you very much for this video!

That belt trick was quite the twist!

Sir thanks for making this channel.

Belt trick is insane. This man always gives the fact.

I find it really cool that you're doing mental health sponsors in a science channel, keep up the great work!

Nice model for spin half particles

After seeing the belt trick, this may explain how easy a slinky can be tangled and now we have a way to undo what seams impossible with a double overlap. To the stairs.

Would it make a difference if I spin the electron or walk around it instead? What will give me each of the scenarios?

This used to bugged me in High School. Thanks for the explaination.

Great video, cousin!

I swear, I never watched a better video explaining the behaviour of electrons

Genius as always

Did a 360 in my room. Interior changed.

Amazing!

Analogies for understanding electrons have three things in common: they are helpful to a degree, they conflict with each other, and are fundamentally wrong. So far the only accurate description is from QFT, which is just math, and sadly doesn't easily whisper any intuitive understanding.

very cool¡¡¡¡ I want to know how you did the trick of the white ball

A fantastic analogy on the tip of the proverbial iceberg that is quantum mechanics! I had to proctor my first quantum mechanic class, this level of counter intuitive “non-relativistic”reality takes a bit of time to wrap one’s head around. So to be able to explain it simply takes some considerable effort. Hell, I remember just the introduction to quantum mechanics changed my perspective of what is “reality”. Anyway, very cool vids my dude!

Nice trick

this is amazing

My brain exploded with madness when I saw the belt illustrations. And that's not even me exaggerating. Right on!!!

you should go to Penn and teller fool us show! great video!

Wow! This is amazing physics!

Your videos are sooo coool

8:49 wow this is relativity all over again I love it!

You're amazing ✨

Now I am confused. The two spatial rotations required to return the electron to its original state, is to be expected in the first place, is it not ? The axis of the spin of an electron is not merely a spatial axis. The axis also extends across a certain measure of the dimension of time. So with this being a 4 dimension spin, one clearly expects exactly what you observe from a mere 3D perspective.

This guy is so informative

Wouldn't this indicate that there is an absolute orientation of space itself? Like the book with the belt closed in it. You move. The belt moves. The book stays the same. Therefore, only two states for particles, because they are embedded in something which maintains its orientation and has absolute position and absolute direction and therefore gives absolute vector velocity (not everything is relative).

Tysm

Going under the book is also making the ends of the belt to twist

Best visual assumption of electron spin on the Internet.

Thanks! next time I happen go around an electron I'll keep this in mind

Enjoyed the geared electron models, thanks. Individual full-rotation handle cycles compare closest to interactions with single photon wave cycles. What electrons do while they're occupying orbitals is not detectable. One could say orbitals (stable electron states) are compact quantum event horizons and when an electron is induced to jump between a hierarchy of event horizons with different allowed energies it has to do a relatively large and exposed re-adjustment cycle whereby a photon is emitted or absorbed. To emit and reabsorb an identical photon, while potentially avoiding detection of any jumps between states, a quick sequence of two exposed electron pirouettes is called for, two exposed electron cycles to return to the same state. A photon is basically created in the image of an exposed electron dancing probably only once around an atom, an image with a definite direction. My 2 cents there, anyway. Vacuum-energy and electron mass inertia collectively assure photon leading and trailing edge overshoot/damping, I suppose. I sincerely believe interested people could do a whole lot worse getting their information elsewhere.

yay some fine good perfecc content

For anyone who wants a clarification: When you turn around the electron by 360⁰ you add something to the wavefunction that will not affect any measurement, so you will measure everything the same (for example: the spin direction, position, etc), meaning you actually CANNOT tell the difference by any means. But, if you take an electron in a superposition of two states, and rotate it by 360⁰ only in one of them, only then could you actually measure it and see it affecting measurements.

those animations blew my mind

Cool vid! Sponsor ads should be at the start or end of the content to prevent interference or distraction in learning interesting advanced physics ideas. Thanks for your attention.
