Quotes about science

If it can't be expressed in figures, it is not science; it is opinion.

Service men are not brighter than civilians. In many cases civilians are much more intelligent. That was the sliver of justification underlying the attempted coup d' etat just before the Treaty of New Delhi, the so-called 'Revolt of the Scientists': let the intelligent elite run things and you'll have utopia. It fell flat on its foolish face of course. Because the pursuit of science, despite its social benefits, is itself not a social virtue; its practitioners can be men so self-centered as to be lacking in social responsibility.

There are but two ways of forming an opinion in science. One is the scientific method; the other, the scholastic. One can judge from experiment, or one can blindly accept authority. To the scientific mind, experimental proof is all important and theory is merely a convenience in description, to be junked when it no longer fits. To the academic mind, authority is everything and facts are junked when they do not fit theory laid down by authority.

Experience is indeed essential to science, but its role is different from that supposed by empiricism. It is not the source from which theories are derived. Its main use is to choose between theories that have already been guessed. That is what ‘learning from experience’ is.

Science can destroy religion by ignoring it as well as by disproving its tenets.

Kuhn's theory suffers from a fatal flaw. It explains the succession from one paradigm to another in sociological or psychological terms, rather than as having primarily to do with the objective merit of the rival explanations. Yet unless one understands science as a quest for explanations, the fact that it does find successive explanations, each objectively better than the last, is inexplicable.

The truly privileged theories are not the ones referring to any particular scale of size or complexity, nor the ones situated at any particular level of the predictive hierarchy—but the ones that contain the deepest explanations.

The overwhelming majority of theories are rejected because they contain bad explanations, not because they fail experimental tests.

Our best theories are not only truer than common sense, they make more sense than common sense...

To say that prediction is the purpose of a scientific theory is to confuse means with ends. It is like saying that the purpose of a spaceship is to burn fuel. … Passing experimental tests is only one of many things a theory has to do to achieve the real purpose of science, which is to explain the world.

I was reading in the paper the other day about those birds who are trying to split the atom, the nub being that they haven't the foggiest as to what will happen if they do. It may be all right. On the other hand, it may not be all right. And pretty silly a chap would feel, no doubt, if, having split the atom, he suddenly found the house going up in smoke and himself torn limb from limb.

It is more difficult for a modern scientist to be a serious Christian, like Polkinghorne, than to be a serious Muslim, like the Nobel Prize-winning physicisit Abdus Salam. Salam happily proclaimed his Muslim faith but did not feel any need to write books about it. For Salam, the idea of a conflict between his faith and his science was ludicrous. Muslim faith has nothing to do with science. But Polkinghorne writes books to prove to himself and to us that his theology and his science can live together harmoniously..
