I’ve never seen such a good explanation of the experiment. The textbook description leaves the reader confused. But this visualization answers all one’s questions.
Few questions: 1) Magnets normally align opposite, North-to-South, not North-to-North; why are these Magnetic-moments aligning North-to-North? 2) Presuming random distribution of incoming orientation, why are all deflected equally? In other words, if a silver atom's outer-electron-spin happens to already be in perfect magnet alignment, there presumably would be no force on that atom and it wouldn't be defected? 3) If electrons have spin, protons have spin too. Has this experiment been shown for single protons?
I also don't get 2) and it seems like the spin is about it. It's this weird property that they called spin. I haven't found any logical explanation for that. I just wondered if we could treat particles as small magnets and they just very, very fast rotate accordingly to magnetic field and that's why they land only in 2 spots. But I don't think it's the solution because someone would come up with it already.
imo: 1) Its a convention which spin has which magnetic orientation. 2) Spin can only be up or down and not in between, so all deflected equally. 3) Single protons (and electrons) would be deflected by the Lorentz (e-magnetic) force, you'd need to balance the charges out first somehow to get just the spin of the electrons.
Good stuff. My question: As the electrons (on the Ag atoms) are travelling they must be in superposition of spin up and spin down states. But when they enter the magnetic field their spin wave functions are collapsed - I suppose they must be because they reveal their states? What do you think. Sorry about the hard headache-question.
Overall this is a very good video, explaining the role of unpaired electrons and how they align with the field. But there is one thing I find missing - there isn't much focus on the fact that the magnetic field is inhomogenous. The explanation seems to omit the role of the magnetic field's gradient entirely.
Spin can only be clockwise or anticlockwise and (Pauli exclusion principle) can only have a spin up and and a spin down in the same orbit. Its like Mobius strips: you cannot lay one m strip on top of another m strip (they don't fit together) unless the M strips are opposite twisted to each other. Try it with paper Mobius strips, you'll see.
@@balabuyew Free lying electrons have a charge of one (each) and will be deflected by any magnetic field but its not the spin deflecting them its the charge. So they no good for this experiment. Same with protons, no good.
Este normal sa nu admiteti ce nu scrie in manuale. Dar dupa ce se descifreaza constanta de actiune h si cu legile electromagnetismului, rezulta structura bipolara a electronului. Inpartiti lungimea de unda a fotonului gama electronic la 137 si apoi la 2.pi si o sa obtineti raza clasica a electronului. Ceeace dovedeste ca electronul este unda stationara bipolara de mare amplitudine a fotonului gama electronic. Si ca fotonul gama ca orisicare foton are exact masa particulei din care se naste prin mecanismul reactiei de anihilare. It is normal not to admit what is not written in the manuals. But after deciphering the action constant h and the laws of electromagnetism, the bipolar structure of the electron results. Divide the wavelength of the electronic gamma photon by 137 and then by 2.pi and you will get the classical radius of the electron. Which proves that the electron is the high-amplitude bipolar standing wave of the electronic gamma photon. And that the gamma photon, like any photon, has exactly the mass of the particle from which it is born through the mechanism of the annihilation reaction.
I found out abt this experiment in a comment section and wanted to know what its about out of curiosity but it ended up strengthening my understanding of a chapter I am studying in school right now, structure of atom. I was able to connect the dots which I studied before as facts.. Our textbook didn't mention about this experiment, its probably there in higher studies. I think it would have been really helpful if they did add it.
Not bad, but what about explaining the behaviour between inhomogeneous and homogeneous fields. Visually, one could come up with the same explanation for homogeneous fields which is wrong.
Ok , but what about the magnetic moment of the atom as a whole, which is due to the rotation of the electrons in the orbits around the nucleus , it can also interfere with the magnets ?
In my opinion conservation of momentum explains your question, each paired electron has opposite magnetic moment (spin) thus the overall magnetic moment is compensated and only the unpaired electron dictates the magnetic moment of the whole particle.
Let us make an incredible conclusion in this experiment! When there is no observer while we are performing the experiment, the valence electron in the silver atom can have a superposition of spin states. This is why it should show a fringe pattern on the detector. Once we start "observing" the silver atoms, the silver atoms' valence electrons collapse to spin up or spin down, and this is why we see two fringes only. This effect will be even more pronounced when we use multiple magnetic slits instead of one as shown in the original experiment! Glory be to quantum mechanics, hurrah!!
This was almost perfect, but does not explain why this result is different from the classical prediction that the atoms should have a continuous distribution on the screen.
4:27 You're saying the magnetic field does a measurement on the atom?????? That's just plain false. The correct explanation is that the electron is in a superposition. The spin up component gets deflected up, and the spin down component get deflected down. The superposition lasts until the electron is measured by the wall at one of the two positions.
Collapse of the quantised time dependent wave function of said electrons during interference with the quanta dynamics of the magnetic field, resulting in a binary random result. You can infer alot about quantum mechanics from stuff like this
Quantum Entangled Twisted Tubules: When we draw a sine wave on a blackboard, we are representing spatial curvature. Does a photon transfer spatial curvature from one location to another? Wrap a piece of wire around a pencil and it can produce a 3D coil of wire, much like a spring. When viewed from the side it can look like a two-dimensional sine wave. You could coil the wire with either a right-hand twist, or with a left-hand twist. Could Planck's Constant be proportional to the twist cycles. A photon with a higher frequency has more energy. (More spatial curvature). What if gluons are actually made up of these twisted tubes which become entangled with other tubes to produce quarks. (In the same way twisted electrical extension cords can become entangled.) Therefore, the gluons are actually a part of the quarks. Mesons are made up of two entangled tubes (Quarks/Gluons), while protons and neutrons would be made up of three entangled tubes. (Quarks/Gluons) The "Color Force" would be related to the XYZ coordinates (orientation) of entanglement. "Asymptotic Freedom", and "flux tubes" make sense based on this concept. Neutrinos would be made up of a twisted torus (like a twisted donut) within this model. Gravity is a result of a very small curvature imbalance within atoms. (This is why the force of gravity is so small.) Instead of attempting to explain matter as "particles", this concept attempts to explain matter more in the manner of our current understanding of the space-time curvature of gravity. If an electron has qualities of both a particle and a wave, it cannot be either one. It must be something else.
In everyday life its good to know what's causing it all to happen. If you no idea you might think spirits are controlling everything and telling you to do things, like suck tulips or take a dump whenever it rains.
So what kind a electrons are in Cathode tubes, in old fashion TV's? Are they purified electrons? 😂 as "ordinary electrons" are with magnetic field inside the tv always and every single one bending on well defined way through magnetic field. But these are "special" imported from Switzerland required to prove quantum physic.😂
The experiment doesn't work with ordinary electrons, which are moved by a straight forward coil or magnetic field as in a TV tube (an old one). The force is not on the spin of the electrons rather the charge of the electron. But this experiment uses silver atoms that are charge neutral so a magnet will not move them.

It didnt explain why the magnetic field is inhomogenous which is a very important detail
I must agree, this video is great! Props to the original creators and for this channel for translating it!
There's a lot of details that are not explained. Its as hard as the conclusions of Quantum Eraser experiment - that is dubious imo.
This was the best visual explanation I have seen on this. Thank you! This really increased my understanding.
I've watched at least 20 videos on the SG experiment and this is the first one that actually explains it.....THANK YOU SO MUCH.
I think this is an awesome experience. It makes is understand or at least imagine what might actually be happening. Great video.
this is the only video that clearly explained this experiment

How is spin determined or caused?

Great clear video ... thanks. I look forward to checking out your channel. Subscribed. Cheers ...
Super clear, thank you.
I don’t think the spin line up with the magnetic field since angular momentum is conserved like a gyroscope
Yeah, I suppose they must emit a photon when aligning?
Good explanation.
Spin is a directional thing. Why spins of paired electrons should be opposite and not just different? When you say "spin up", what is "up"?
Spin can only be clockwise or anticlockwise and (Pauli exclusion principle) can only have a spin up and and a spin down in the same orbit. Its like Mobius strips: you cannot lay one m strip on top of another m strip (they don't fit together) unless the M strips are opposite twisted to each other.

What would be the result of the experiment if the magnetic field were homogeneous?
Nothing would happen (no e-m force as the atoms are neutral charged), spin detection needs an inhomogeneous field for some reason idk.
If all the silver atoms have the unpaired electron with spin up then how does that experiment tell us anything about the electron spin?
what do you mean? I think the spin is not defined before entering the B-field
Not bad, but what about explaining the behaviour between inhomogeneous and homogeneous fields. Visually, one could come up with the same explanation for homogeneous fields which is wrong.

This was almost perfect, but does not explain why this result is different from the classical prediction that the atoms should have a continuous distribution on the screen.
The magnetic field acts like a recording device and forces the atom to take an either spin up or spin down orientation.
made my day!

There are so many rules seeking those explanations. Just a picture is a thousand words. This is a nice video.
