Continuous rotation and translation symmetries

## Before the animation

Chapter lines 171–171:

What rotations return a circle to itself? All of them! Similarly, all translations return a line to itself. The symmetries of space and time are continuous and can therefore be represented as transformations that depend on continuously varying parameters.
