Anyone else would have gone home grumpy, but he went home with an idea. He borrowed a neighbor’s physics textbook and got to work learning about the principles of mechanical advantage and stored energy and by 1966 he had worked it out enough that he patented the compound bow (patent granted in 1969), called the greatest innovation in archery since the first crude use of a piece of wood and a sinew string.
His son Douglas wrote, “As I remember, dad borrowed a high school physics book from a neighbor and studied the section on mechanics, paying particular attention to one basic formula: K.E. =
