In physics, I've moved from electric current to magnetism. There is a distinct mathematical symmetry between magnetic and electric fields, as expressed in Maxwell's laws of electromagnetism, so I've been wanting to organized the two subjects somewhat in parallel. I found a phrase in an older physics textbook that gives me a handle on it. Directed current elements are to the magnetic field what magnetism what electric charges are to the electric field. A major difference is that current elements don't exist in isolation. That gives me an implortant clue to organizing my discussion of magnetism.
In psychology, I've progressed from consciousness to mentation. I've expanded information a little on Confucius, Jesus, and Paul, I've moved from considering Demography to human ecology (nodding in the direction of Katrina), from language to literature, frlom clothing and dress to buildings, and from families to education. I'm doing a top level review of what I call sociology, and I've moved from the Latin group of western peoples to the germanic group.
