Cute! I like how 8i is the mom. Very fitting. What are those imaginary number kids 3i and 5i playing with down there on the real number line?
Cartoonist: They’re using the real numbers 1 and 4 as swords. I’m imagining that the mom probably also said: “Put those down! Those are real.”
Interviewer: Is that vertical dashed line the imaginary number line?
Cartoonist: Yes. Since i, the square root of -1, doesn’t exist on the real number line, you can represent it by having it float above 0. When you consider multiples of i (1i, 2i, 3i, etc…) it forms that vertical imaginary number line.
Interviewer: I like how these imaginary numbers are more “life-like” than the real numbers!
Cartoonist: Well that’s part of the message here. Even though we call them “imaginary,” they are actual numbers. Imaginary numbers aren’t any more “pretend” or “fictitious” than real numbers.
