Do computers think It isn’t a new question. In fact, Alan Turing, a British mathematician, proposed an experiment to answer the question in 1950, and the test, known as the Turing Test, is still used today. In the experiment, a group of people are asked to interact with something in another room through a computer terminal. They don’t know whether it is another person or a computer that they are interacting with. They can ask any questions that they want. They can type their questions onto a computer screen, or they can ask their questions by speaking into a microphone. In response, they see the answers on a computer screen or they hear them played back by a voice synthesizer. At the end of the test, the people have to decide whether they have been talking to a person or to a computer. If they judge the computer to be a person, or if they can’t determine the difference, then the machine has passed the Turing Test.

Historically, schools in the United States have borrowed the European system of school organization, a system that separates students into grades by chronological age. In general, children begin formal schooling at the age of six in what is referred to as the first grade. For the most part, students progress through twelve grades; however, some students who do not meet minimum requirements for a particular grade may be asked to repeat the year.
Graded schools are divided into primary grades, intermediate grades, and secondary grades. Primary education includes grades 1 through 5 or 6, and may also provide kindergarten as a preparation for first grade. Referred to as elementary school, these grades are usually taught by one teacher in a selfcontained classroom. Intermediate grades begin with grade 6 or 7 and offer three years of instruction. At this level, teams of teachers may collaborate to provide subject-based classe

The jet stream is an irregular band of wind that occurs in high altitudes at about 20,000 feet, that is, between 6 and 9 miles above the surface of the Earth. Consequently, the jet stream wanders near the top of the Earth’s troposphere, and, coincidentally, that is exactly where most of the Earth’s weather patterns occur. It is helpful to think of the jet stream like a river of air that occurs at several different locations, but in general flows from west to east over the middle latitudes. Technically, to be called a jet stream, the winds should be moving faster than 57 miles an hour, but it can have average core speeds of 190 miles per hour, and in the winter, when the jet stream is strongest, winds have been clocked at 300 miles an hour. For the most part, the winds are stronger in the winter because during the winter months the surface temperature contrasts more with the temperature in the troposphere. To put that another

| Time spent in a bookshop can be most
enjoyable, whether you are book-lover or merely you are there to buy a book as a
present. You may even have entered the shop just to find shelter from a sudden
shower. Whatever the reason, you can soon become totally unaware of your
surroundings. The desire to pick up a book with an attractive dust-jacket is
irresistible, although this method of selection ought not to be followed, as you
might end up with a rather dull book. You soon become engrossed in some book or
other, and usually it is only much later that you realize you have spent far too
much time there and must dash off to keep some forgotten appointment-without
buying a book, of course. This opportunity to escape the
realities of everyday life is, I think, the main attraction of a bookshop.
There are not many places where it is possible to do this. A music shop is
very much like a bookshop. You can wander about these places to your heart’s
content. If it is a good shop, no assistant approach you with inevitable
greeting: "Can I help you" you needn’t buy anything you don’t want. In a
bookshop an assistant should remain in the background until you have finished
browsing. Then, and only then, are his services necessary. Of course, you may
want to find out where a particular section is, but when he has led you there,
the assistant should retire carefully and look as if he is not interested in
selling a single book. You have to be careful not to be
attracted by the variety of books in a bookshop. It is very easy to enter the
shop looking for a book on ancient coins and to come out with a copy of the
latest best-selling novel and perhaps a book about brass-rubbing-something that
had vaguely interested you up until then. This volume on the subject, however,
happened to be so well illustrated and the part of the text you proved so
interesting that you had to but it. This sort of thing can be very dangerous.
Apart from running up a huge account, you can waste a great deal of time
wandering from section to section. |
