100 Years anniversary: Stern-Gerlach Experiment 1922 (U2-07-03)

The Stern-Gerlach experiment, performed in 1922, delivered the first experimental proof of the fascinating degree of freedom of an electron spin.

Btw, props for the video being pi minutes long

[mixervishant]

Anyone learn anything easily by 3d projections ..
Your video is really useful for me..

[jeremyhofmann]

I watched a dozen videos trying to explain spin for 20 minutes and none made it as clear as this one. Thanks!

[akshaymore]

Finally someone made a video with *perfect* explanation.
Thank you. 👍🏻👍🏻👍🏻

Great! I was confused about this experiment because I was thinking about it in the context of a uniform magnetic field.

[m.c.]

The amount that a magnet deflects in a magnetic field, depends on how long it takes to flip, so if the magnet flips immediately, it will separate exactly like the stern Gerlach experiment.
Large radius objects spend a lot more time turning than objects with a smaller radius.

the explanation was clear and precise.thank you

[averylawton]

I've always had trouble grasping the spin thank you

Tribute to great experimental physicist Otto Stern, who was born OTD in 1888 and who along with Gerlach discovered spin quantization 100 years ago in this month i.e. in Feb. 1922.

Really nice video, You helped me a lot of to understand this experiment. Thanks!

It's 2022 i.e 100 year anniversary of this experiment..🥰

Wow, great work brother. Thank you very much

This is the first video that I could find that actually talked about the instrumentation that's used to actually measure any of this. I want to know what instruments they use to measure spin and how they calculate the 'spooky action at a distance' that sounds more and more like bullshit. Where are the instruments?

A beam of silver atoms were generated in an atomic beam furnace... please explain this process

[discoveringthegardenofeden]

I am stunned. This experiment does not seem to show what it has been purported to show:

The silver atom, being a spinning charge spinning around a nucleus, behaves like a magnet and this 'effect' increases when exposed to the magnetic force of the setup. Magnets either instantly align or go topsy turvy in a greater magnetic field. When I see this experiment I can only deduce that Spin up spin down is a result of the experimental setup, it is not inherent to the silver atom/electron. The fact that the magnetic field is inhomogeneous is a deceptive notion, because in reality the witness plate does not show the amount of tilt of the atom/electron. It merely shows that the only excluded position is perpendicular to the inhomogeneous magnetic field, which for spinning objects (such as vortices, gyroscopes) at the interface of two forces is entirely expected even in classical mechanical systems because that perpendicular position is unstable (example: a spinning gyroscope when spinning down skits away when the sides droop down and touch a surface/opposing force interface, it cannot remain in the latter position).

Repeat the given experiment with a second set of magnets at a given distance. It may be possible to refine the results.

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.

video...visualizing things always helps so much

[abhanaik]

Thank you ! Great explanation and great video!

This universe reserves so many surprises... Quantum world is amazing
