Certainly Newton considered some theoretical aspects of it in his writings, but he was reluctant to go to sea to further his work.
For most people the sea was remote, and with the exception of early intercontinental travelers or others who earned a living from the sea, there was little reason to ask many questions about it, let alone to ask what lay beneath the surface. The first time that the question "what is at the bottom of the oceans?" Had to be answered with any commercial consequence was when the laying of a telegraph cable from Europe to America was proposed. The engineers had to know the depth profile of the route to estimate the length of cable that had to be manufactured.
It was to Maury of the US Navy that the Atlantic Telegraph Company turned, in 1853, for information on this matter. In the 1840s, Maury had been responsible for encouraging voyages during which soundings were taken to investigate the depths of the North Atlantic and Pacific Oceans. Later, some of his findings aroused much popular interest in his book The Physical Geography of the Sea.
The cable was laid, but not until 1866 was the connection made permanent and reliable. At the early attempts, the cable failed and when it was taken out for repairs it was found to be covered in living growths, a fact which defied contemporary scientific opinion that there was no life in the deeper parts of the sea.
Within a few years oceanography was under way. In 1872 Thomson led a scientific expedition, which lasted four years and brought home thousands of samples from the sea.
Their classification and analysis occupied scientists for years and led to a fivevolume report, the last volume being published in 1895.
The proposal to lay a telegraph cable from Europe to America made oceanographic studies take on ______.
A.an academic aspect
B.a military aspect
C.a business aspect
D.an international aspect
Most meetings are sometimes thought to be___.
A.solving many problems
B.discussing important matters
C.killing time and uninteresting
Yet there is another important aspect of advertising that should not be forgotten: that of choice. A number of advertisements for different brands of the same product, e.g. toothpaste, shampoo or washing powder allow the consumer to choose. Choice is an important part of buying.
In this busy day and age, there is little time for comparison shopping. To determin which product is the best to buy, and at the most competitive price, consumers these days rely on advertising in its various forms. This saves time and energy and simplifies shopping. So for busy people like you and me, advertisements actually do us a favor.
What is the dual function of advertisements?
A.To sell and to inform.
B.To increase prices and competition.
C.To change the means of selling and buying.
D.To take away chances of choosing from customers.
One consequence from studying the possibility of computer thought was that we were forced to examine with new care the idea of thought in general. It soon became clear that we were not sure what we meant by such terms as thought and thinking. We tend to assume that human beings think, some more than others, though we often call people thoughtless or unthinking. Dreams cause a problem, partly because they usually happen outside our control. They are obviously some type of mental experience, but are they a type of thinking? And the question of nonhuman life forms adds further problems. Many of us would maintain that some of the higher animals—dogs, cats, apes, and so on—are capable of at least basic thought, but what about fish and insects? It is certainly true that the higher mammals show complex brain activity when tested with the appropriate equipment. If thinking is demonstrated by evident electrical activity in the brain, then many animal species are capable of thought. Once we have formulated clear ideas on what thought is in biological creatures, it will be easier to discuss the question of thought in artificial machines. One of the great benefits of AI research is that we are being forced to examine more closely the working of the human mind.
It is already clear that machines have superior mental abilities to many life forms. No tree can play chess as well as even the simplest computer; nor can frogs repair car bodies as well as robots. It seems that, viewed in terms of intellect, the computer should be set well above plants and most animals. Only the higher animals can, it seems, compete with computers with regard to intellect.
