You have just chauvinistically declared the mathematics of thousands of years and hundreds of cultures to be "n[o]t mathematics"; not to mention all of the experimental and not-yet-formalized current research; not to mention all of the checkbook balancing done by millions of people who never saw a "symbol of logic" in their lives.

Ordinary arithmetic (2+2=4, etc.) was formalized some time ago. So too has algebra, calculus, differential equations, etc. As for "experimental" research, it will always be just a preliminary work until it can be axiomatized.

I really have to admire those have staked their careers on such speculative ventures, hacking their way through tractless mathematical jungles, but failure is real possibility. But I guess it wouldn't be very exciting otherwise!
