don't confuse numerical system & numbers itself == any proper numerical system can express any number. Another moment is how efficient that expression could be.

no, the very point is, you must uniform objects before you do operations on them. that proof messes w/ two different types of objects. for instance, 1/3 is odd or even? or let p,q \in \mathbb{N}\; \frac{p}{q}=\epsilon,\; p=\epsilon\cdot q everything looks fine out there, right? But we have the damn grave problem, even two ones...
 p=\epsilon\cdot q exists everywhere for any p & q. second form has two troubling cases == 1st one w/ q = 0 and 2nd one is that..
\displaystyle \lim_{q \to \infty}\lim_{p \to \infty}\frac{p}{q}\eq????
