1. In Current Science, spin is an intrinsic property of certain elementary particles which is a form of angular momentum, usu. pictured as a rotation; a vector representing this in the case of a particular particle.
2. In Neu Theory, spin has two specific meanings:
- Spin is one of two perpetual movement/energy forms of nature, and is one of the four primal physical quantities of nature. Spin has five absolute properties;
- G-Spin (quantum spin) is the perpetual constant one-way rotation of:
