[简答题]Scientific methodology is based on generating hypotheses and testing them to see if they make sense; in laboratories throughout the world, researchers spend at least as much time trying to disprove a theory as they do trying to prove it. Eventually, those ideas that don’t prove false are accepted. But fingerprinting was developed by the police, not by scientists, and it has never been subjected to rigorous analysis—you cannot go to Harvard, Berkeley, or Oxford and talk to the scholar working on fingerprint research. Yet by the early twentieth century, fingerprinting had become so widely accepted in American courts that further research no longer seemed necessary, and none of any significance has been completed.
The discussion of fingerprinting is only the most visible element in a much larger debate about how forensic science fits into the legal system. For years, any sophisticated attorney was certain to call upon expert witnesses to assert whatever might help his cas

[简答题]Technology is the application of scientific method and knowledge to industry to satisfy our material needs and wants. This results in new processes and in new products, such as washing machine, record players, motor ears, electronic computers, nuclear weapons and space rockets. A technologist has the scientific know-how, or technique, for making and doing things. The know-how may be original, as it is devised for a specific purpose, or it may be inherited as the accumulated skill and knowledge of generations of specialists.
We live in a technological society. Almost every aspect of life in the modem world is influenced (for better or worse) by your technological surroundings. 46) Communications, transportation, manufacturing, mining and exploration, the service industries, medicine, agriculture-all are dominated bi methods and apparatus which are the results of technological advances. The basis of technology is science. 47) Without the fundamental discoveries and underst
[填空题]Popper says that the scientific method is hypothetico-deductive.
[填空题]The ’scientific method’ is more a way of describing research than a way of doing it.
[简答题]The method of scientific investigation is nothing but the expression of the necessary mode of working of the human mind: it is simply the mode by which all phenomena are reasoned about and given precise and exact explanations. The difference between the operations and methods of a baker weighing out his goods in common scales, and the operations of a chemist by means of his balance is not that the scales in the one case, and the balance in the other, differ in the principles of their construction or manner of working; but that the latter is a much finer apparatus and of course much more accurate in its measurement than the former.
Probably there is not one here who has not in the course of the day had occasion to set in motion of a complex train of reasoning, of the very same kind, though differing in degree, as that which a scientific man goes through in tracing the causes of natural phenomena.
[简答题]
61) The method of scientific investigation is nothing but the expression of the necessary mode of working of the human mind; it is simply the mode by which all phenomena are reasoned about and given precise and exact explanation. There is no more difference, but there is just the same kind of difference, between the mental operations of a man of science and those of an ordinary person, as there is between the operations and methods of a baker or of a butcher weighing out his goods in common scales, and the operations of a chemist in performing a difficult and complex analysis by means of his balance and finely graded weights. It is not that the scales in the one case, and the balance in the other, differ in the principles of their construction or manner of working; but that the latter is much finer apparatus and of course much more accurate in its measurement than the former.
You will understand this better, perhaps, if I give you some familiar examples. 62) Yo
