Stern Gerlach experiment

[markse68]

stumbled upon this delightful old demonstration of the Stern Gerlach experiment from 1967 on youtube. It’s quite something to see the real apparatus rather than a graphic and I feel I understand its significance a lot better now. An essential tool for investigating “spooky action at a distance” and Bell’s theorem.

Thank you for sharing, I’d forgotten all about this!

What a lovely film and a very nice demonstration. Good  to see an old experimental rig too.  I’m old enough to remember using chart recorders to capture data. 🙂  thanks for the link.

Nice.

Interestingly for such a fundamental important result, more than 100 years passed before the original 1922 German publication (1:45 of video) was translated into English.

I too am old enough. As a student I used chart recorders in physics labs.
