Science is the organized skepticism in the reliability of expert opinion

Physics is to mathematics what sex is to masturbation.

It is scientific only to say what is more likely and what less likely, and not to be proving all the time the possible and impossible.

Poets say science takes away from the beauty of the stars - mere globs of gas atoms. I, too, can see the stars on a desert night, and feel them. But do I see less or more?

Mathematics is a language plus reasoning. It's like a language plus logic. Mathematics is a tool for reasoning.

Another thing I must point out is that you cannot prove a vague theory wrong.

What is necessary for 'the very existence of science,' and what the characteristics of nature are, are not to be determined by pompous preconditions, they are determined always by the material with which we work, by nature herself. We look, and we see what we find, and we cannot say ahead of time successfully what it is going to look like. ... It is necessary for the very existence of science that minds exist which do not allow that nature must satisfy some preconceived conditions.
