Here’s my simple test for a product of
today’s technology: I go to the bookstore and check the shelves for remedial
books. The more books, the more my suspicions are raised. If
computers and computer programs supposedly are getting easier to use, why are so
many companies still making a nice living publishing books on how to use
them Computers manipulate information, but information is invisible. There’s nothing to see or touch. The programmer decides what you see on the screen. Computers don’t have knobs like old radios. They don’t have buttons, not real buttons. Instead, more and more programs display pictures of buttons, moving even further into abstraction and arbitrariness.

[单项选择]How exactly, does science work How do scientists go about doing science Ordinarily we think science proceeds in a straight-forward way. Ideally scientists make observations, formulate hypotheses (假设), and test those hypotheses by making further observations. When there is difference between what is observed and what is predicted by the hypothesis, the hypothesis is revised. Science proceeds in this way, which is a gradual method of finding the best fit between observation and prediction.
But this idealized version of how one does science is naive. Although science demands proof that observations made by one observer be observable by other observers using the same methods, it is by no means clear that, even when confronted with identical phenomena, different observers will report identical observations. And it is most certain that, even if the same observations are made, the conclusions as to the meaning of the observations frequently differ.
