As it is shown in the first part of this short essay, duality plus conservation laws allow the violation of Bell’s inequalities for any spatio-temporal separation. To dig deeper into particle dualism, in the second part, a class of models is proposed as a working framework. It encompasses...

Since the curve is a group of transformations, the directional derivative at [itex] (x,y) [/itex] is determined by what the transformation does to the point [itex] (x,y) [/itex] by values of [itex] \alpha [/itex] close to zero. I'd think that some advanced calculus book so...
