Science,  in  practice,  depends  far  less  on  the  experiments  it  prepares  than  on  the   preparedness  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 about 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 falling 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 as faithfully as the reports in the science journals  indicate, then  it  is perfectly  logical  for management to  expect research to produce results measurable in dollars and cents. It is entirely reasonable for auditors to believe that scientists who know exactly where they are 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  researchers  in  favor  of  more  conventional thinkers "who work well with the team."
