Abstract
Symmetries play a fundamental role in physics, and knowledge of their presence in certain problems often simplifies the solution considerably. We illustrate this with the help of three important examples.

Only proper rotations represent a continuously connected group. Improper rotations contain a reflection in space, which is a discrete transformation. Therefore all rotations including improper ones form a disconnected group.
