Science, in practice, depends far less on the experiments it prepares than on the prepared

ness of the minds of the men who watch the experiments. Sir Isaac Newton supposedly discovered gravity through the fall of an apple. Apples had been falling in many places for centuries and thousands of people had seen them fall. But Newton for years had been curious a- bout the cause of the orbital motion of the moon and planets. What kept them in place？ Why didn’t they fall out of the sky？ The fact that the apple fell down toward the earth and not up into the tree answered the question he had been asking himself about those larger fruits of the heavens, the moon and the planets.

How many men would have considered the possibility of an apple failing up into the tree？ Newton did because he was not trying to predict anything. He was just wondering. His mind was ready for the unpredictable. Unpredictability is part of the essential nature of research. If you don’t have unpredictable things, you don’t have research. Scientists tend to forget this when writing their cut and dried reports for the technical journals, but history is filled with examples of it.

In talking to some scientists, particularly younger ones, you might gather the impression that they find the "scientific method" a substitute for imaginative thought. I've attended research conferences where a scientist has been asked what he thinks about the advisability of continuing a certain experiment. The scientist has frowned, looked at the graphs, and said "The data are still inconclusive." "We know that," the men from the budget office have said, "but what do you think？" Is it worthwhile going on？ What do you think we might expect？" The scientist has been shocked at having even been asked to speculate.

What this amounts to, of course, is that the scientist has become the victim of his own writings. He has put forward unquestioned claims so consistently that he not only believes them himself, but has convinced industrial and business management that they are true. If experiments are planned and carried out according to plan is faithfully as the reports in the science journals medicate, then it is perfectly topical for management to expect research to produce results measurable ill dollars and cents. It is entirely reasonable for auditors to believe that scientists who know exactly where they arc going and how they will get there should not be distracted by the necessity of keeping one eye on the cash register while the other eye is on the microscope. Nor, if regularity and conformity to a standard pattern are as desirable to the scientist as the writing of his papers would appear to reflect, is management to be blamed for discriminating against the "odd balls" among re- searchers in favor of more conventional thinkers who "work well with the team".

The autor wants to prove with the example of Isaac Newton that ______.

A．inquiring minds are more important than scientific experiments

B．science advances when fruitful researches are conducted

C．scientists seldom forget the essential nature of research

D．unpredictability weighs less than prediction in scientific research
