Second, we confess that although he made good choices, Elvis does not know calculus.
In fact, he has trouble differentiating even simple polynomials. More seriously,
although he does not do the calculations, Elvis’s behavior is an example of the uncanny
way in which nature (or Nature) often finds optimal solutions. Consider how
soap bubbles minimize surface area, for example. It is fascinating that this optimizing
ability seems to extend even to animal behavior. (It could be a consequence of natural
selection, which gives
