It took the two of them the better part of half an hour to get the unit into place; to disguise its presence; and to make proper power connections. Ishie had objected at first to connecting it up, and Mike explained his insistence by saying that "If it looks like something that works, nobody will look at it twice. But if it looks like something dead, one of my boys is apt to take it apart to see what it's supposed to be doing." He didn't mention his real reason--a heady desire to run a few tests on the instrument himself. The job done, the two sat back on their heels, admiring their handiwork like bad boys. "Coffee?" asked Mike. "Snarl. Honorable ancestor Confusion doesn't even need to tell me what to do now. My toy is safe. I am going to bed. I have worked without stopping for two days and now the flare has stopped me. "Confusion decide to relent. He tell me now: 'He who drive self like slave for forty-eight hours is nuts and should be sent to bed.' I hope," he added, "that the hammocks are soft; but I don't think I shall notice. I know just where to go for I checked in once to fool the Sacred Cow before I went to get my beautiful. Now I go back again." And without so much as a thank-you, he staggered out, grasping for hand-holds to guide himself in a most unspacemanlike manner. * * * * * Mike craftily sat back, still on his heels beside the object, and watched until Ishie had disappeared, and then turned his full interest to the playtoy that fortune had placed in his shop. Without hesitation he removed the false front they had so carefully put in place. He still had a long tour of duty ahead, and it was very unlikely that he would be interrupted, or, if interrupted, that anyone would question the object on which he worked. It would be assumed that this was just another piece of equipment normally under his care. Carefully he looked over the circuits, checking in his mind the function of each. Then he went to his racks and began selecting test equipment designed to fit in the empty racks around it. Oscilloscope, signal generator, volt meters and such soon formed a bank around the original piece of equipment, in positions of maximum access. Gingerly he began applying power to the individual circuits, checking carefully his understanding of each component. The magnetic field effect, Ishie had explained; but this three-phase RF generator--that puzzled him for a while. Then he remembered some theory. Brute strength alone would not cause the protons to tip. Much as a top, spinning off-center on its point, will swing slowly around that point instead of tipping over, the spinning protons in the magnetic field would precess, but would not tip and line up without the application of a rotating secondary magnetic field at radio frequencies which would make the feat of lining them up easy.
