Axiom of Spam (Strong Form): Every mathematical system of sufficient complexity to accomodate e-mail, will eventially be infested by spam. Furthermore, the spam will grow more obnoxious over time; after, perhaps, a single post from a Green Card lawyer, the network will become inundated by sex spam.

of that mathematical branch itself. You might be able to prove every conceivable statement about numbers within a system by going outside the system in order to come up with new rules and axioms, but by doing so you ... Gödel showed that provability is a weaker notion than truth, no matter what axiom system is involved ...

However, we still use the first intuition as a ground for our fundamental theories of physics, which represent space and time using the mathematical continuum. I4 leads easily to the axiom that a real-valued measure exists on the continuum, and indeed on Euclidean 3-space.
