Single Idea 21165

[catalogued under 27. Natural Reality / B. Modern Physics / 4. Standard Model / c. Particle properties]

Full Idea

Spin is a quantum-mechanical property of a particle akin to rotation about its own axis. Particles of different spins respond to magnetic fields in different ways, so it is a relatively easy thing to measure.

Gist of Idea

Spin is akin to rotation, and is easily measured in a magnetic field


New Scientist writers (Why the Universe Exists [2017], 04)

A Reaction

I wish I knew what 'akin to' meant. Maybe particles are not rigid bodies, so they cannot spin in the way a top can? It must be an electro-magnetic property. Idea 21166 says spin has two possible directions.
