Tribute to Otto Stern a German-American physicist and 1943 Nobel laureate in physics.
Otto Stern 17 February 1888 – 17 August 1969) was a German-American physicist and Nobel laureate in physics. He
was the second most nominated person for a Nobel Prize with 82 nominations in the years, ultimately winning in
1943.
As an experimental physicist Stern contributed to the discovery of spin quantization in the Stern–Gerlach
experiment with Walther Gerlach in February 1922 at the Physikalischer Verein in Frankfurt am Main; demonstration
of the wave nature of atoms and molecules; measurement of atomic magnetic moments; discovery of the proton's
magnetic moment; and development of the molecular beam method which is utilized for the technique of molecular
beam epitaxy.
He was awarded the 1943 Nobel Prize in Physics, the first to be awarded since 1939. It was awarded ...

The Stern-Gerlach Experiment (ESI College Physics Film Program 1967)
This film on The Stern-Gerlach Experiment featuring MIT Professor Jerrold R. Zacharias was produced in 1967 as part of the College Physics Film Program by Educational Services, Inc. (ESI), later Education Development Center (EDC), which grew out of the project known as the Physical Science Study Committee (PSSC). Some of the content was developed by the Science Teaching Center (STC), later Education Research Center (ERC), at MIT.
This is a 16mm projection filmed by a digital camera.
This apparatus is currently in hibernation but had been used for a number of decades in MIT's Junior Physics Laboratory while having its parts gradually replaced or upgraded with components like stepper motors.

The Stern-Gerlach Experiment And The Discovery Of Electron Spin - Sandip Pakvasa [2016]
Abstract:
the lecture describes the story of how Stern and Gerlach tried to detect "space quantization" of Bohr orbits and ended up discovering the spin of the electron; and how it took five years to disentangle the muddle. I will also discuss briefly the vexing story of a possible Stern-Gerlach experiment for free electrons. I will note in passing the remarkably creative career of Otto Stern, sometimes (justifiably) called the founding father of Experimental Atomic Physics.

Otto Stern | Wikipedia audio article
This is an audio version of the Wikipedia Article:
Otto Stern
Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.
Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain
Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

Stern-Gerlach Experiment - explained simply and clearly
Hi everyone. This video is about the Stern-Gerlach experiment. In this experiment, silver is heated so much in a furnis that it becomes gejus. A few individual silver atoms leave the furnis through a small epetscher in the direction of an inhomojeneous magnetic field. Behind the magnetic field there is a photo plate which the silver atoms hit and leave an imprint. The result is that the silver atoms are deflected either up or down. Some of you might now think that the distraction is due to the Lorentz force. However, these are not positively or negatively charged particles that fly through the magnetic field. They are complete silver atoms with an equal number of protons and electrons. Therefore, no resulting Lorentz force acts on the silver atoms.
Let's take a closer look at the silver at...

Otto-Stern Award 2023 of the GDCh Division of Magnetic Resonance to Jean Jeener
Jean Jeener, the pioneer of two-dimensional nuclear magnetic resonance spectroscopy (NMR) provides insight into his transformative invention, which revolutionized NMR. The two experiments proposed by him (COSY and NOEY) are still cornerstones of structure determination of molecules important in structural chemistry and structural biology.
Jean Jeener, der Pionier der zweidimensionalen kernmagnetischen Resonanzspektroskopie (NMR) gibt in einem Interview Einblicke in seine transformative Erfindung, die die Kernresonanzspektroskopie revolutionierte. Die zwei von ihm vorgeschlagenen Experimente (COSY und NOESY) sind immer noch Säulen der Strukturbestimmung von Molekülen in der Strukturchemie und –biologie.

Otto Stern 17 February 1888 – 17 August 1969) was a German-American physicist and Nobel laureate in physics. He
was the second most nominated person for a Nobel Prize with 82 nominations in the years, ultimately winning in
1943.
As an experimental physicist Stern contributed to the discovery of spin quantization in the Stern–Gerlach
experiment with Walther Gerlach in February 1922 at the Physikalischer Verein in Frankfurt am Main; demonstration
of the wave nature of atoms and molecules; measurement of atomic magnetic moments; discovery of the proton's
magnetic moment; and development of the molecular beam method which is utilized for the technique of molecular
beam epitaxy.
He was awarded the 1943 Nobel Prize in Physics, the first to be awarded since 1939. It was awarded to Stern alone,
"for his contribution to the development of the molecular ray method and his discovery of the magnetic moment of
the proton" (not for the Stern–Gerlach experiment). The 1943 prize was actually awarded in 1944.
After Stern retired from the Carnegie Institute of Technology, he moved to Berkeley, California. He was a regular
visitor to the Physics colloquium at UC Berkeley. He died in Berkeley on 17 August 1969.
The Stern-Gerlach-Medaille of the Deutsche Physikalische Gesellschaft awarded for excellence in experimental
physics is named after him and Gerlach.

Hi everyone. This video is about the Stern-Gerlach experiment. In this experiment, silver is heated so much in a furnis that it becomes gejus. A few individual silver atoms leave the furnis through a small epetscher in the direction of an inhomojeneous magnetic field. Behind the magnetic field there is a photo plate which the silver atoms hit and leave an imprint. The result is that the silver atoms are deflected either up or down. Some of you might now think that the distraction is due to the Lorentz force. However, these are not positively or negatively charged particles that fly through the magnetic field. They are complete silver atoms with an equal number of protons and electrons. Therefore, no resulting Lorentz force acts on the silver atoms.
Let's take a closer look at the silver atoms. A silver atom has 47 electrons. The electrons are at different energy levels. It is already noticeable that there is an even number of electrons at every energy level, only one is at the highest energy level. Let's take a closer look at the electrons. The Pauli principle states that no two electrons on a shell may have completely the same quantum numbers.
The main quantum number indicates the shell on which the electron is located, in simple terms the distance between the electron and the atomic nucleus. Let's start with the two electrons on the K shell. The secondary quantum number (s, p, d or f) indicates the shape of the orbital in which an electron is located with a probability of 90%. The magnetic quantum number m indicates the orientation of the orbital shape.
At first glance, one might think that the two electrons on the K shell are the same in all quantum numbers. But according to the Pauli principle, they are not allowed to do that. However, if we take a closer look at the two electrons, we notice a difference.
The final missing quantum number of an electron, the spin is what differentschiates these two electrons.
The left electron has a spin-down and the right electron has a spin-up. These two electrons, which have completely identical quantum numbers except for the spin, are called paired electrons. If you look at the electrons on the other shells, you can see that they consist entirely of paired electrons. Only on the highest shell there is a single unpaired electron. This electron can assume both spin states: spin-down or spin-up, without breaking the Pauli principle. Now let's go back to our experiment. As already mentioned, whole silver atoms always fly through the magnetic field. Now let's look at what happens to all 46 paired electrons as they fly through the magnetic field. The spins of the two electrons must be opposite at all times. Otherwise they would break the Pauli principle. Before entering the magnetic field, the spins are oriented in all possible directions. When entering the magnetic field, the spins align with the magnetic field. In this case the spin of the left electron points in the same direction as the magnetic field and the spin of the right electron points in the opposite direction. An atom that consists only of paired electrons is not deflected in the magnetic field. But the silver atom has an unpaired electron. If this enters the magnetic field, it aligns itself either in the direction of the north pole or in the direction of the south pole. The most important thing is the alignment before entering the magnetic field. If the alignment is previously directed towards the North Pole, the spin is in most cases completely aligned to the North Pole.
In this case, this unpaired electron experiences an upward force. It can thus be shown that the spin of the electron has a magnetic moment and is either attracted by the north pole, as in this example, and repelled by the south pole and deflected upwards, or, as in the second example, exactly in the opposite direction.

Behind the magnetic field there is a photo plate which the silver atoms hit and leave an imprint. The result is that the silver atoms are deflected either up or down. Some of you might now think that the distraction is due to the Lorentz force. However, these are not positively or negatively charged particles that fly through the magnetic field. They are complete silver atoms with an equal number of protons and electrons. Therefore, no resulting Lorentz force acts on the silver atoms.
Let's take a closer look at the silver atoms. A silver atom has 47 electrons. The electrons are at different energy levels. It is already noticeable that there is an even number of electrons at every energy level, only one is at the highest energy level. Let's take a closer look at the electrons. The Pauli principle states that no two electrons on a shell may have completely the same quantum numbers.
The main quantum number indicates the shell on which the electron is located, in simple terms the distance between the electron and the atomic nucleus. Let's start with the two electrons on the K shell. The secondary quantum number (s, p, d or f) indicates the shape of the orbital in which an electron is located with a probability of 90%. The magnetic quantum number m indicates the orientation of the orbital shape.
At first glance, one might think that the two electrons on the K shell are the same in all quantum numbers. But according to the Pauli principle, they are not allowed to do that. However, if we take a closer look at the two electrons, we notice a difference.
The final missing quantum number of an electron, the spin is what differentschiates these two electrons.
The left electron has a spin-down and the right electron has a spin-up. These two electrons, which have completely identical quantum numbers except for the spin, are called paired electrons. If you look at the electrons on the other shells, you can see that they consist entirely of paired electrons. Only on the highest shell there is a single unpaired electron. This electron can assume both spin states: spin-down or spin-up, without breaking the Pauli principle. Now let's go back to our experiment. As already mentioned, whole silver atoms always fly through the magnetic field. Now let's look at what happens to all 46 paired electrons as they fly through the magnetic field. The spins of the two electrons must be opposite at all times. Otherwise they would break the Pauli principle. Before entering the magnetic field, the spins are oriented in all possible directions. When entering the magnetic field, the spins align with the magnetic field. In this case the spin of the left electron points in the same direction as the magnetic field and the spin of the right electron points in the opposite direction. An atom that consists only of paired electrons is not deflected in the magnetic field. But the silver atom has an unpaired electron. If this enters the magnetic field, it aligns itself either in the direction of the north pole or in the direction of the south pole. The most important thing is the alignment before entering the magnetic field. If the alignment is previously directed towards the North Pole, the spin is in most cases completely aligned to the North Pole.
In this case, this unpaired electron experiences an upward force. It can thus be shown that the spin of the electron has a magnetic moment and is either attracted by the north pole, as in this example, and repelled by the south pole and deflected upwards, or, as in the second example, exactly in the opposite direction.
