Engineering is an endless confrontation with Mother Nature owing to her ob-stinant denial of linearity. The virtue of Her stubbornness is not obvious in the heat of battle, but consider the alternative. Were Her world faithful to a linear persuasion there would be no engineering, at least as we know it. All problems would be accompanied by their unique solutions, thereby inhibiting creativity. Indeed, there would be little excitement in any aspect of human endeavor under the code of linearity, not unlike discovering the North Pole ... a hollow victory.
