He was fairly certain about the outcome of various sports events. But when it came to science, he discovered whole worlds of which he had only heard vaguely before. There were things which he understood only with difficulty, and he began to realize, with a sense of shock, how inadequate his school "science" classes had been. But he didn't worry; he could easily predict that this class of question would have to do either with something medical or something about atomics. He found a great deal of already predicted material in both those fields; every magazine had a doctor writing about which disease would be conquered next, and how soon; and a number of articles gave details on how soon atomic power plants would be running, and what kinds of bombs would be tested next. Don's choice of accountancy had been motivated by a liking for logic and orderliness; he began to find a fascination in the logic and orderliness of science. His picture of a scientist had been vague at best, a picture formed from newspaper photos of Einstein, with his white hair blowing, and of movie scientists, bending over strange machines and creating monsters. At one point Don found the history and viewpoints of science drawing him into reading that could not possibly be used in the questioning. Reluctantly, and resolving to go back to that area, he moved on. _The oil workers union has a contract which runs out next month_, he wrote, _and they have always had a strike at this point in their last few years. If they do strike, there will probably be a temporary shortage of fuel and gasoline. This might be the right answer if the question is, What strike is affecting the country most now?_ Back into politics once more, Don began to extend his guessing, as he read further. _The UN investigation of the situation in South Africa will be resumed, and the South African delegation will withdraw again. It looks as if there is a very good chance of native rebellions in French North Africa, so that a question which pointed to Africa might deal with either situation._ After a while, Don had worked around to the Far East, and became more and more interested. His orderly habits led him into a pattern in which he organized the most likely events into a future history which covered, in detail, the things that would happen in the whole world, to a point that went into the next few years. In fact, he noticed abruptly, the vista ahead had grown brightly clear, and was still extending. He told himself that when he returned, he would continue to write his history of the future. Just for fun, though, he said to himself. Nobody would be really interested in such a thing except himself, and he was no writer. But it looked as if he might have found a real hobby, Don told himself. Why, he didn't even miss television. * * * * *
