The Standard Model Theory of the Strong Interactions

A shirk schwartz and jone a, i think, made one of the fundamental observations, that string theory really wants to be a theory of gravity. The standard model type one theory had gravity plus a gauge, but we're missing a cirality. Was called cirality of matter. So if you look at, say, the electron, all the particles standard model a, they have a two kinds, two, two. If my fingers point in the direction that the particle is spinning, and my thumb points in the direction of the momentum, then what i'm describing right now is a left handed spin a if, well, depending on how your camers, if your sins
