The theory of the spinning ball. A-B, line of flight. C-C, axis
of revolution. M-N, direction of revolution. First four fingers
show, axis C-C at right angles with line xf flight (A-B). One side
of the ball moves faster than the other, creating unequal pressure.
In the last two the axis parallels the line of flight, like the rifle bul
let and the ball travels straight and true.
