So we're celebrating the real numbers, but maybe we should hoist up the illusory numbers? Back in the day, they thought that some numbers were "imaginary" numbers (e.g. sqrt(-1)) and nowadays, engineers use those imaginary numbers all the time and they feel as real as the reals. So, here's to math keeping our imagination limber and extending our ideas of what's real.
