Tom,
Do you agree with Feynman? I know your great love for the mathematical...
"Physics is not mathematics, and mathematics is not physics. One helps the other. But in physics you have to have an understanding of the connection of words with the real world. It is necessary at the end to translate what you have figured out into English, into the world, into the blocks of copper and glass that you are going to do the experiments with. Only in that way can you find out whether the consequences are true. This is a problem which is not a problem of mathematics at all." (Feynman, 1965, p. 49).
"Mathematicians are only dealing with the structure of reasoning and they do not
really care what they are talking about. They do not even need to know what they
are talking about, or, as they themselves say, whether what they say is true." (Id.)
"In other words, mathematicians prepare abstract reasoning ready to be used if
you have a set of axioms about the real world. But the physicist has meaning to
all his phrases." (Id.)
"Mathematicians like to make their reasoning as general as possible,...[whereas]
the physicist is always interested in the special case." (Feynman, 1950, p. 50)
"[T]he poor mathematician translates [the special case] into equations, and as the symbols do not mean anything to him he has no guide but precise mathematical
rigour and care in the argument." (Id.)
Therefore, it is up to the physicist to narrow the scope of the problem and define what is required of the mathematician in rather specific terms.
Strangely enough, Feynman concluded his discussions on the relation of mathematics to physics with the following observation: "the mathematical rigour of great precision is not very useful in physics." (Id., pp. 50 - 51) The reason is that great precision can dampen or limit the intuition and creative imagination of the physicist, which he needs in order to modify his original ideas or guess at new solutions. (Id., p.51) An approximate mathematical conclusion is often more helpful.
