I can make it go either way at will, but the shadow is definitely a blooper.

I am 52 left 48 right.
Gokul43201 said:Good point! The shadow breaks the degeneracy. I can only picture her going clockwise (looking from above), but absent the shadow, I know that she can be just as easily pictured going counter-clockwise. Still, after a minute or so of trying (with the shadow hidden), I couldn't get myself to picture a counter-clockwise rotation.

Moonbear said:No, the shadow will appear to move that same direction too. It just looks like it's entering from the other side of the screen.

is she spin 1/2 or integer spin, i.e. is she a fermion or a boson?

Maybe I can't get her to reverse because of the Pauli Exclusion Principle...:uhh: Waah!Astronuc said:So now the really important question is -

jimmysnyder said: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.Chi Meson said: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.
