2、uires logical reasoning, chess would seem to be perfectly suited to the computer .all a programmer has to do is give the computer a program evaluating the consequences of every possible response to every possible move, and the computer will win every time. In theory this is a sensible approach; in p

3、ractice it is impossible. Today, a powerful computer can analyze 40 000 moves a second. That is an impressive speed. But there are an astronomical number of possible moves in chessliterally trillions. Even if such a program were written (and in theory it could be ,given enough people and enough time

4、), there is no computer capable of holding that much data.Therefore, if the computer is to compete at championship levels, it must be programmed to function with less than complete data. It must be able to learn from experience, to modify its own programm, to deal with a relatively unstructured situ

5、ationin a word, to “think” for itself . In fact, this can be done. Chess-playing computers have yet to defeat world champion chess players, but several have beaten human players of only slightly lower ranks. The computers have had programs to carry them through the early, mechanical stages of their

6、chess games. But they have gone on from there to reason and learn, and sometimes to win the game.There are other proofs that computers can be programmed to learn, but this example is sufficient to demonstrate the point. Granted , winning a game of chess is not an earthshaking event even when a compu

13、You Call This a Good Economy这能称之为上佳经验You have to have lived in the 1950s and 1960s to have experienced a good economy. In the period between 1950 and 1970 it was the rulerather than the exceptionthat an ordinary family, without higher education, could sustain itself decently on the income of a singl

14、e breadwinner（养家糊口的人）. In 1955, when I was 19 and living in Brooklyn, N. Y., my father, who had a sixth-grade education, maintained our family of five on a wage of $82 a week as a bookbinder. My mother taught us fairness and compassion; my father, discipline and enterprise.The U. S. economy in those

15、 years was good. Then where did this good economy go? It was inflated away. The price of gold, which I take as proxy for the prices of all goods, was $35 an ounce in those years. It is at roughly ten times that price today.There is another answer, though: inflation caused the entire work force to be

16、 moved into higher tax groups, thus reducing after-tax purchasing power. That is, my fathers bindery job in1954 paid $82 a week, with $80 after deductions; today, at $ 820 per week the net would be $662.To ordinary people, the economy doesnt look very good at all. After-tax incomes continue to decre

17、ase in purchasing power. The jobs offered in the employment ads pay only a little more than the minimum wage, maybe $5 an hour, which, after payroll deductions, yields $4 an hour. Compare that with minimum-wage jobs of the early 1950s, when 75 cents was worth todays $7.50 before and after taxes.Note

24、ut common sense is useful now as it ever was. No amount of expertise substitutes for an intimate knowledge of a person or a situation. At times you just have to trust your own judgement.It almost cost me my life to learn that. I was reading a book one day, idly scratching the back of my head, when I

25、 noticed that, in one particular spot, the scratching echoed inside my head like fingernails on an empty cardboard carton, I rushed off to my doctor.“Got a hole in your head, have you?” he teased. “Its nothingjust one of those little scalp nerves sounding off.”Two years and four doctors later, I was

26、 still being told it was nothing. To the fifth doctor. I said, almost in desperation,”But I live in tis body. I know somethings different.”“If you wont take my word for it,Ill take an X-ray and prove it to you,” he said.Well, there it was, of course, the tumor that had made a hole as big as an eye s

And Im too docile in the face of authority. I should ha
