It took me a while to get used to, since there is no "action" in the
direction of the vector, only a mathematical formalism.
But it is a convenient way of uniquely defining the 1) speed, 2)
orientation, and 3) clockwise/counterclockwise sense of a spinning object -
such as a gyroscope, planet, or electron.
