That's interesting. Does Coq let you change axioms? In what
Feynman called "Persian" mathematics, you're interested in what
axioms support a given theorem, not the other way around as in
"Greek" mathematics.
My wife (who's a mechanical engineer) were just discussing how
calculus is regarded as the "hard mathematics" in college. But I
wonder if it's a matter of how it's taught. When she and I went
school a lot of calculus was learning tricks and approximations to
do integration. Conceptually it wasn't that hard. And in
applications, nobody worries much about the tricks anymore because
they just give it a computer. Mathematica knows the tricks and
there's easy numerical integration algorithms. Does that mean we
are losing contact with how it actually works...not at all. Those
tricks and approximations just obfuscated "what was really going
on".
I wonder how calculus is taught now in high school and undergrad
college courses? ISTM is could be much clearer and conceptual and
easier to learn.
