I did

Yes

Never heard of them. I was looking for a pic and all I could find were b&w shots of hairy men.

so an average Friday night for you?

A bit early yet, but yes.

There is a weird part of my imagination that clings to classical features. But though spin is something that even in a quantum expression looks and feels like a momentum and like a spinning pinball, but that is incomprehensible when you just work with it like that. You have to throw that imagination over bord and just look at spin as an abstract feature of symmetry. An electron is no tiny ball nor a cloud of electric charge with a tiny mass.

It is a trope of features that do not really relate to classical imaginations. And spin is not a momentum or anything spinning at all, the term spin as such is a misleading bitch and clings to classical images of rotating masses. I would like it better if we had a better term as it really is not spinning at all. Though the Hamilton equivalent looks very much like a spin momentum. But that similarity is misleading since it comes from a classical mathematical expression that clings to mechanics.

You get aware that these nice classical imaginations tumble down as spin can have values like +1/2 or -1/2. and the value isn't connected to mass or speed of rotation. Spin is rather a clumsy and misleading term for the symmetry features of an electron. It acts and "looks" differently when observed from different point of view. Like an egg. An egg is not a sphere and looks differently when seen from the side, from top and from the bottom it has a distinct symmetry in one axis and no symmetry in others.

And no, electrons are no eggs and have no mechanical symmetry whatsoever. Physics operates with tropes, not the tiny pyramids, spheres and cubes we did like so much. Why? Because nature is brutal. Nature tells us that the things are not any of those imaginations we had and that when we insist to act as if they were we see that our predictive powers fail. When you insist that dynamite is a cigarette and light it it will blow into your face.

Luckily most of the time imagining them as tiny balls is sufficient when i work on optoelectronic devices

Haha, are yours also blue spheres with a white minus sign?

in my mind electrons are red and holes are blue

Neutrons are light green in my mind! ;)

I thought protons were the red balls .. is my memory failing me?

you could be right, maybe the electrons were the blue ones
