Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. Who discovered Spin (physics)?Concept proposed in 1925, building on experimental observations from 1922
2. What is the applications?Magnetic Resonance Imaging (MRI), spintronics (data storage, electronics), quantum computing
3. What is spin in physics?Spin is an intrinsic property of tiny particles, like a built‑in spinning top. It is a kind of angular momentum that the particle has no matter where it is. The amount of spin is fixed for each type of particle.
4. Why do particles have spin?Spin exists because experiments showed that particles behave as if they have a tiny magnetic compass inside them. The experiments could not be explained by the particles orbiting around something else, so scientists said the spin is part of the particle itself.

Intrinsic Angular Momentum: An inherent angular momentum possessed by a particle, independent of its motion.
Spinor: A mathematical object that describes spin-1/2 particles and transforms non-trivially under rotations.
Spin-Statistics Theorem: A theorem linking a particle's spin value to its quantum statistical behavior (Fermi-Dirac or Bose-Einstein).
