For example, the mass of an electron is really a coupling between a left handed electron and a right handed electron, which is the antiparticle of a left handed positron. "

" The reference modes that perhaps are most important in computing are: (1) descriptive, i. e. , the model describes the original. If the deviation from model to original cannot be tolerated then the model has to be changed. Analysis models are in a descriptive reference mode to their originals. (2) prescriptive, i. e. 3d Molecular Model, the model prescribes the original. If the deviation from model to original cannot be tolerated then the original has to be changed. "
