"Well, I kept an eye on him after that and about a week later Jerry brought home some calculus dealing with a new design he's developing. He ran into trouble with it and sweated and swore for an hour, while Timmy sat and read and I kept peeking in the hall mirror that lets you see into the front room from the kitchen. After a while Jerry left the room to look for some tables he wanted and Timmy slipped over and looked at his work, made a single notation, then dived back to his book as Jerry returned. Jerry started to sweat over the thing again, then suddenly did a double-take. He made some erasures and in five minutes had the whole thing worked out, cursing himself for misreading a figure or something.
"Now don't tell me it was just a coincidence. Timmy hadn't seen that problem before and it should have been miles over his head anyway, yet he gave it a quick glance, spotted the error, changed the limits of an integration and put Jerry on the right track. Just like that."
Phil carefully massaged a dry plate even drier.
"So I stagger back and gasp, 'I can't believe it!' or something insane but appropriate. The disturbing thing to me is that I not only _can_ believe it, I do believe it. Completely. I may as well tell you now what I haven't yet told anyone else, that I've been methodically tricking Timmy for some months past--in fact, ever since I began to suspect that his knowledge of the sciences was, to say the least, unusual for a boy his age. I probably led him into making that slip with Jerry, identifying the curve. By giving him the impression that any boy his age would know far more chemistry, math and physics than is actually the case, I tripped him into revealing that he himself knows a very great deal about them. Perhaps more than I do.
"I begin to suspect now that I didn't set my sights nearly high enough in leading him on, but God alone knows where he could have learned. On anything that could be related to the humanities he's very slow, but in the physical sciences he's out of this world. His secluded life--unable to mix with other kids, go to shows, games, or do anything that gets him into crowds--gives him a very limited background for understanding his environment, leaves him unboyish. He doesn't understand people. I constantly have the impression that he is anxious to do the right thing, but is simply baffled by problems in human relations."
