In physics, "spin" is a fundamental property of particles, similar to charge or mass. It is an intrinsic form of angular momentum carried by elementary particles, composite particles (hadrons), and atomic nuclei. Spin is a quantum mechanical phenomenon that does not have a direct classical analogue. Key aspects of spin include: 1. **Quantization**: Spin can take on only certain discrete values, characterized by quantum numbers.
