John Gabriel is by far one of the worst and most vicious trolls ever to appear on sci.math. He is a malicious fraud. In his Wacky New Calculus, which he tries to pass off as some kind of legitimate alternative:
1. He is unable to prove something as simple as 2+2 = 4.
2. There are no irrational numbers, so the distance between (0, 0) and (1, 1), for example, is undefined.
3. His definition of the derivative of a function just doesn't work. If, for example, f(x)=x^3, then f'(0), which should be 0, is also undefined.
4. To make it work it all, he has also had to redefine the basic rules of logic!
