... • Q is not complete: limits that “ought” to exist in Q fail to do so, e.g., 2. • Q is not algebraically closed: polynomials that “ought” to have solutions in Q fail to do so, e.g., X 2 + 1. The smallest complete field containing Q is the real numbers R. But R is not algebraically closed, e.g., X 2 + ...

Infinitesimals Abstract
... Consequently, whenever only infinitesimals or infinite hyper-reals support the derivation of a result, the Calculus of Limits on the real line, fails to deliver that result. No neighbourhood of a hyper-real is homeomorphic to an \n ball. Therefore, the hyper-real line is not a manifold. The hyper-re ...

Countability
... Proof (onto): If y ∈ Z is non-negative, then f (2y) = y. Therefore, y has a pre-image. If y is negative, then f (−(2y + 1)) = y. Therefore, y has a pre-image. Thus every y ∈ Z has a preimage, so f is onto. Since f is a bijection, this tells us that N and Z have the same size. Now for an important de ...
