Fred,
Thanks. The equation's assumptions mean it only selectively models nature. a,b are something like tied parallel 'bivectors', but only one accessible. Perhaps each (identical) particle may then be something like E = a-b/b-a, both subject to cos theta. In fact even that can't be all right as I falsified the = sign and Law of the Excluded Middle in last years essay!
The question is, is E really just E, or is it really E_tot = vector independent = E_ccw = E_cw. In which case it seems the equation you gave may be a tautology using the assumptions it's based on.
Lets use an analogy to check a few concepts. Your car is up on axle stands with the wheels turning. We have a hand dynamometer. On the off side, both sides of the tyre have the same E, in fact checking 'inside' (under the car) and out, we have not only the same E in two sets of two opposite directions, but find the same with everything at 90^o as well!
Then we go round to the other side of the car, and find exactly the same, all reversed! Now which 'directions' are and which are - ? And would that change if the car was on it's roof?
In the scenario of the equation, plus an minus are not just the same value E but the same 'thing'. They are a nominal false description, and entirely observer dependent. I've found the problem is all about the way humans think, and may need as big a step as Copernicus identified. As I say in the paper, there is no 'up' in space.
I suspect that is what Joy's mathematopological approach may help resolve, if it includes the attributes of real physical dynamics.
Or perhaps as a short answer to your question; we can get E(a, b) = -a.b. by simply tuning the observer of the equation upside down. If he's in space he really won't notice! Whichever way up A or B are the total E will always be the same if measured on the axis.
I moved away from prediction by manipulating ancient Arab symbols some decades ago (Mayan ones are more interesting!) so if you have any good ideas for simple representations of the discrete dynamics described I'd be delighted for you to have all the kudos.
Best wishes.
