Itis just the (wrong) claim of set theory that aleph_0 is a quantitythat is contradicted here.We have one side of lenght 1*aleph_0 and the other side of lengthsqrt(2)* aleph_0. According to Cantor these are quantities, aleph_0 iseven a "whole number", in English commonly called intteger.>> If you have two triangles, you can use the lengths of two sides and the> angle between them to see if they are congruent.

If you have one angle and the completelengths of its sides, then you have constructed a perfect triangle -in geometry.>> If you can't specify real coordinates for the vertices, they don't exist,> and you do not have a triangle.What you say sounds, if translated from geometry into algebra (and youcertainly know that both are only different languages for the samecontents): If you can't specify a last number in N, then N has nocardinality.But matheologians are not that precise. In case of matheology theydeny the identity of algebra and geometry. And in geometry they acceptcompleted infinity for the height and the diagonal of my triangle. Butthey do not recognize that this would imply completed infinity for thewidth of said triangle. It is only a very minor difference. Amathematician, however, will also be disturbed by very small errors.Therefore matheology is not a part of mathematics.Regards, WM
