Regardless of this example, do you really think that all mathematical
results would really produce a physical result?

Math is a descriptive tool to help quantify physical relations and
actions.  Math cannot force the relation-action.

It might provide insight if it captures the essence of the physic, but
it cannot 'make' it.

You read many of these posts.  What makes a math incorrect?  Because
it doesn't apply to the physic you want it to?  Why should any math be
a sole dictator of a physic?  We hardly know the physic to start with..

The math 'applications' are fine when restricted to the bounds of the
physic.  They are also fine when they are a pure math.  Thus the
difference.

I fully agree with what you said.
Specific with the sentence:
Mathematics is a descriptive tool to help to quantify the
physical relations.

The question to ask what type of mathematics is
necessary to describe (understand as much as possible)
all of physics ?

What kinds of tools do you need to disassemble, refurbish, and
reassemble a car engine? Can you do with a screwdriver, a hammer, and
an adjustable wrench? Probably. But who would want to?

If the problem is that you don't have the resources to acquire and get
competent at the tools, then you probably shouldn't attempt to be a
car mechanic. If you long to be a car mechanic, then acquiring the use
and facility of needed tools will be a task so obvious you won't think
twice about it.

There are far too many people in these groups who dream of being a
star mechanic but have no desire to gather the proper tools and get
good at using them. That's what makes them hobbyists.

PD


Are complex numbers required ?
Can you do without them ?
