My Stern Gerlock magnet has this pointy north end and this flat south end.

I have a particle source that's shooting the electrons through the magnetic field.

The classical prediction, which is this blacked-in eye, says the particle could end up anywhere there.

Now you might ask, why is it this I shape?

And the answer is because as you move,

The the strongest effect is right straight down the center.

And as the particle drifts off to one side or the other, the magnetic field is no longer as inhomogeneous and the the effect then just damps down.

So so the eye kind of

goes like that.

Um whereas in the quantum mechanical case, all that black middle is gone, right?

Things will that's the the particles will not show up in the middle.

They'll either all be di the each one will either be deflected up or it'll be deflected down.

Again, the the eye shape for the same reason because the magnetic field is

Is going down.

So there's the quantum mechanical prediction.

Um, very different than the classical prediction, if you want to say

what's a good experimental reason to think that quantum mechanics is doing something right here that classical mechanics wasn't doing.

Um and now I want to show you and I love I like to do this because I this is a wonderful thing.

This is the actual data.

Um, this is the data that Stern and Gerloch got when they first did this experiment.
