Brian; Quantum spin is an intrinsic value pertaining to quantum physics only. I personally view it as a physical spherical volume influenced by the a physical particle and thus increases or decreases according to Planck's constant. It really has not equivalent relation in classical physics terms (angular velocity). You should add this web site to your favorites; it is useful most of the time for answering physics questions. http://en.wikipedia.org/wiki/Spin (physics)

Mr nobody; You are looking at strong force and weak force as if they are independent quantities. Gravity, Strong force, and weak force are interdependent proportional relationships. If one changes, they all change proportionally. Your logic is flawed and totally based on gibberish.
