This "sir, yes sir" business, which would probably sound like horseshit to any civilian in his right mind, makes sense to Shaftoe and to the officers in a deep and important way. Like a lot of others, Shaftoe had trouble with military etiquette at first. He soaked up quite a bit of it growing up in a military family, but living the life was a different matter. Having now experienced all the phases of military existence except for the terminal ones (violent death, court-martial, retirement), he has come to understand the culture for what it is: a system of etiquette within which it becomes possible for groups of men to live together for years, travel to the ends of the earth, and do all kinds of incredibly weird shit without killing each other or completely losing their minds in the process. The extreme formality with which he addresses these officers carries an important subtext: your problem, sir, is deciding what you want me to do, and my problem, sir, is doing it. My gung-ho posture says that once you give the order I'm not going to bother you with any of the details--and your half of the bargain is you had better stay on your side of the line, sir, and not bother me with any of the chickenshit politics that you have to deal with for a living. The implied responsibility placed upon the officer's shoulders by the subordinate's unhesitating willingness to follow orders is a withering burden to any officer with half a brain, and Shaftoe has more than once seen seasoned noncoms reduce green lieutenants to quivering blobs simply by standing before them and agreeing, cheerfully, to carry out their orders.
He walked straight out of college into the waiting arms of the Navy. They gave him an intelligence test. The first question on the math part had to do with boats on a river: Port Smith is 100 miles upstream of Port Jones. The river flows at 5 miles per hour. The boat goes through water at 10 miles per hour. How long does it take to go from Port Smith to Port Jones? How long to come back?Lawrence immediately saw that it was a trick question. You would have to be some kind of idiot to make the facile assumption that the current would add or subtract 5 miles per hour to or from the speed of the boat. Clearly, 5 miles per hour was nothing more than the average speed. The current would be faster in the middle of the river and slower at the banks. More complicated variations could be expected at bends in the river. Basically it was a question of hydrodynamics, which could be tackled using certain well-known systems of differential equations. Lawrence dove into the problem, rapidly (or so he thought) covering both sides of ten sheets of paper with calculations. Along the way, he realized that one of his assumptions, in combination with the simplified Navier Stokes equations, had led him into an exploration of a particularly interesting family of partial differential equations. Before he knew it, he had proved a new theorem. If that didn't prove his intelligence, what would?Then the time bell rang and the papers were collected. Lawrence managed to hang onto his scratch paper. He took it back to his dorm, typed it up, and mailed it to one of the more approachable math professors at Princeton, who promptly arranged for it to be published in a Parisian mathematics journal.Lawrence received two free, freshly printed copies of the journal a few months later, in San Diego, California, during mail call on board a large ship called the U.S.S. Nevada. The ship had a band, and the Navy had given Lawrence the job of playing the glockenspiel in it, because their testing procedures had proven that he was not intelligent enough to do anything else.
