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. What is the group SO(3)?The mathematical group representing all possible rotations in three-dimensional space
2. What is spin in physics?Spin is a special kind of angular momentum that particles have inside them, even if they aren't actually spinning.
3. Why do electrons have a half‑integer spin?Electrons are fermions, and all fermions have a spin value of 1/2, which means their spin is a half‑integer.

Fermions: Particles with half-integer spin (like electrons), subject to the Pauli Exclusion Principle.
Bosons: Particles with integer spin (like photons), which do not obey the Pauli Exclusion Principle.
Spintronics: A field of electronics that uses the intrinsic spin of electrons in addition to their electric charge.
Isometry: A transformation that preserves distances between points, such as rotation, translation, and reflection.
