Spin (physics)

Spin is an intrinsic form of angular momentum carried by elementary particles

Spin is a fundamental property of particles, intrinsic to their nature. Unlike classical angular momentum, which arises from motion and position, spin is an inherent characteristic of particles. It is a quantum property that cannot be explained by classical physics.

Example

In the Stern-Gerlach experiment, silver atoms demonstrated discrete angular momenta, indicating the quantized nature of spin.

Understanding spin is crucial for explaining particle behavior in quantum mechanics and has significant implications for fields like quantum field theory and particle physics.
