(x, why?) Mini: Real

(Click on the comic if you can't see the full image.)
(C)Copyright 2016, C. Burke.

At our roots, aren't we all a little irrational?

So R>0, the Non-Negative Real number set, is joined by, R, the Real number set; N, Natural numbers; Q, Rational numbers (R was taken); Z, Integers (don't ask); P, Primes; and C, Complex numbers.

I also saw a notation for H, denoting Quaternions -- I didn't even go there. Except to note that Q was taken already because R was taken already.




Come back often for more funny math and geeky comics.

    And O for octonions, which H is a subset of.

    Q comes from "quotient": Z comes from the german word "Zahlen": there's also A for the set of algebraic numbers....

    And H, of course, is for Hamilton, after the guy who discovered quaternions.
