"Common sense" is what most people in a time and place accept. It is not what Carol has arrived at after years of studying mathematics and physics. It is difficult to discuss a book you have not read. "In everyday life, one is primarily concerned with usefulness, whereas science is concerned with rather abstract understanding. This is exemplified by Sherlock Holmes when he turns to Watson, who has been castigating him for not knowing about Copernicus and the solar system and says, "What the deuce is it to me if you say we go around the sun. If we went round the moon it would not make a pennyworth of difference to me or my work."

"In fact one of the strongest arguments for the distance between common sense and science is that the whole of science is totally irrelevant to most people's day-to-day lives." (Wolpert, page 16)

As above, arguments over the Copenhagen Theory have little affect on the lives of most people, even as we depend on quantum mechanics for the design of our electronic computers. Neither does information theory matter to most people on the information superhighway. Millions of people use GPS devices without knowing relativity, or caring one way or the other. That all is common sense. It is not science. The electronic engineers, the information scientists, and the geodetic scientists who created these systems do care about their interaction. A paradigmatic failure in the theory of electron tunneling would shake the foundations of many studies even (or especially) in life sciences and medicine. Many different kinds of scientists would care a whole lot.
