Every movement—leaping, swimming, rolling down a hill—has a geometry to it.
If you follow one part of a moving body, such as a dancer’s forearm, it traces out a straight line, a curve, or an angle.
Moving machines make geometry too—everything from a speeding locomotive…
…to a spinning ride at a carnival.
Creating a mental picture of a space will help you figure out how to navigate through it.
When making a mental plan for a movement, it helps to copy someone else, and to imagine your body moving in the same way.
And even if you can’t see what’s around you, your brain can help you envision the space, and how to move within it.
