In mathematics a triangle is defined by one angle and its two sides.
If the latter are aleph_0, then the third must be a completed infinity
too. As it is not, some elements of this this triangle are not part of
mathematics. What about the angle of pi/4? It is part of mathematics.
Now a person with some intelligence could infer the rest. Not you, of
course.
