When it comes to public relations, the mathematicians can really shoot themselves in the foot. Not only do they call some numbers odd, and some numbers irrational, but then, to make matters worse, they absent-mindedly acquiesce in some numbers being called imaginary. This is quite awful terminology, because it reinforces a stereotype that mathematicians spend their time doing wonderfully complicated work on things that don’t really exist—and hence, by implication, don’t really matter.
