For about three centuries we have been doing science, trying science out, using science for the construction of what we call modern civilization. Every dispensable item of contemporary technology, from canal locks to dial telephones to penicillin, was pieced together from the analysis of data provided by one or another series of scientific experiments. Three hundred years seems a long time for testing a new approach to human interaction, long enough to settle back for critical appraisal of the scientific method, maybe even long enough to vote on whether to go on with it or not. There is an argument.
Voices have been raised in protest since the beginning, rising in pitch and violence in the nineteenth century during the early stages of the industrial revolution, summoning urgent crowds into the streets any day on the issue of nuclear energy. The principal discoveries in this century, all in all, are the glimpses of the depth of our ignorance about nature. Things that used to seem clear and rational, matters of absolute certainty—Newtonian mechanics, for example—have slipped through our fingers, and we are left with a new set of gigantic puzzles, cosmic uncertainties, ambiguities; some of the laws of physics are amended every few years, some are canceled outright, some undergo revised versions of legislative intent as if they were acts of Congress.
Just thirty years ago we call it a biological revolution when the fantastic geometry of the DNA molecule was exposed to public view and the linear language of genetics was decoded. For a while, things seemed simple and clear, the cell was a neat little machine, a mechanical device ready for taking to pieces and reassembling, like a tiny watch. But just in the last few years it has become almost unbelievably complex, filled with strange parts whose functions are beyond today's imagining.
It is not just that there is more to do; there is everything to do. What lies ahead, or what can lie ahead if the efforts in basic research are continued, is much more than the conquest of human disease or the improvement of agricultural technology or the cultivation of nutrients in the sea. As we learn more about fundamental processes of living things in general we will learn more about ourselves.
What CAN'T be inferred from the 1st paragraph？
听力原文： The modern sailing ship was developed by a man who never went to sea. He was Prince Henry of Portugal, the younger son of the Portuguese King and an English princess.
Prince Henry lived in the 15th century. As a boy he became devoted to the sea, and he dedicated himself to improving the design of ships and the methods of sailing them. In 1416, Henry founded a school for mariners, to which he invited everyone who could help him--Jewish astronomers, Italian and Spanish sailors, and Arab mathematicians and map makers who knew how to use the crude compass of the day and improve it.
Henry's goal was to design and equip vessels that would be capable of making long ocean voyages without having to hug the shore. The caravel carried more sail and was longer and slimmer than any ship then made, yet was tough enough to withstand gales at sea. He also developed the carrack, which was a slower ship, but one that was capable of carrying more cargo.
To Prince Henry the world owes credit for the development of craft that made oceanic exploration possible. He lives in history as "Prince Henry the Navigator".
