In my model any spin is real spin, not just an un-explainable phenomenon. Saying that the two electrons in an orbit have just different spins, without explaining what spin means, is just ridiculous. I propose that the two electrons actually spin, and at any instant, their spins are in the same direction with respect to the direction of motion.

I don't think there is any physical idea regarding the spin of photons at present. In my model, the particles of matter in light follows a helical path; the helix may be clockwise or anticlockwise.
