I am not sure if staring at it helps, it might work better if you close your eyes orI totally see it going counter-clockwise. I tried staring at it for a bit to see if it goes the other way, just can't seem to see it like that. I'm not sure it is possible for it to go clockwise, or is it???
There is obviously a pair of women spinning simultaneously in both directions, both occupying the same space. Pauli does not apply here. Definitely a boson.So now the really important question is -
is she spin 1/2 or integer spin, i.e. is she a fermion or a boson?
You guys are all WAY too left-brained to be analyzing the shadow at this level of detail.When she is spinning clockwise, and the foot which is lifted up passes in front of the foot which is planted on the ground, then the shadow of the lifted foot passes in front of the shadow of the planted foot as would be expected.
However, when she is spinning counter-clockwise, and the foot which is lifted up passes in back of the foot which is planted on the ground, then the shadow of the lifted foot still passes in front of the shadow of the planted foot and this is difficult to explain.
I don't think so. The degeneracy is broken by the fact that the observer is on one side of the woman, not by the position of the light source.I can see both directions such that the shadow looks valid. The "slope of the floor" and position of light source both seem to shift.
