Group theory in physics

Group theory in physics studies the mathematical structures called "groups," which describe symmetry. Symmetry refers to the idea that certain properties of physical systems remain unchanged under specific transformations—like rotating a crystal or reflecting a molecule. By understanding these symmetries through group theory, physicists can classify particles, predict their behaviors, and explain fundamental forces. Essentially, it's a powerful language that reveals how the universe’s patterns and structures stay consistent, guiding us in uncovering the underlying rules of nature.
