You are an evil genius. But a more generic branch Banach space theory do have application. For example, Banach spaces are related to Hilbert spaces, which in turn is used massively in 11-dimesnional M-theory.

I tried very hard to be unhelpful!

I agree that Hilbert spaces have many applications. i did study functional analysis for a bit (but I'd be hard-up to tell you anything of value now!).

Many people (perhaps most) will not use any of these topics in their lives. My answer would be that these things are enriching. The same people who ask the point of mathematics are the same people who don't like education, in particular science education. Education rescues us from the small-minded.

Everyone who ever lived assembles before the supreme being. The supreme being tells them. "My message kept getting garbled. What I meant to say was that to get into heaven, you have to pass an entrance exam." And then he hands everyone a math test. The point is that people who think that they know what "really matters" often have no basis for their belief that this or that really matters and the more they try to justify what they do and believe with ultimate pay offs, the less likely they are to have a clue what they are talking about. It's obviously true of religion, but is more generally true of grand philosophies. Getting boatloads of people killed during and in the aftermath of a revolution. all in the name of installing an economic and political system that ends up sucking weasels anyway is something we've seen far too much of in history.

You don't expect me to fall for that? "I have the PERFECT answer, BUT I would rather hear it from YOU guys."

Sounds like you don't know the answer and are fishing for the answer.

HOW do you KNOW you have the PERFECT answer?

IF you have the PERFECT answer, why don't you tell us, bless us with your PERFECTION.

This must be the oldest trick in the book.
