By taking a more mechanical approach for
understanding the most important purpose of any femoral hip prosthesis, we can then better determine the best method for designing a physiologic femoral hip prosthesis, which is most capable of successfully achieving its most important purpose; to transfer load from the pelvis to the proximal femur physiologically [as illustrated in the image above left of Townley's PSL Hip prosthesis].

The rules of nature are mathematical

“For a successful technology, reality must take precedence over public relations, for Nature cannot be fooled.” ---Feynman

The only reason something's impossible is because of the limits of ones imagination and one thing that's difficult for the limited imagination to understand is that the rules of nature are mathematical. The principle of science which says that the ultimate and final judge of whether something is so or not isn't the reason, nor is it a characteristic necessity of science that nature's rules be mathetical. It turns out that you can state mathematical laws, in biomechanical engineering at least, which work to make powerful predictions. Why nature is mathematical is, again a mystery. Knowledge is of no real value if you can tell me what happened yesterday. It is necessary to tell me what will happen tomorrow if you do something—not only necessary, but fun. Not knowing is easy. How you get to know is what’s difficult and often requires that you stick your neck out to find an elusive solution to a complex problem.
