3-D Plot of spin connection on the blog of www.aias.us

It looks clear and very well prepared, and is a three dimensional map of the spin connection. The spacetime current is:

J (spacetime) = curl (omega x A) / mu0

where “spacetime” is equivalent to “aether” or “vacuum”. Clearly, omega is the intermediary between J (spacetime) and A, the usual material vector potential.
