This is an excellent example of how human ingenuity invented complex numbers to link two seemingly unrelated natural constants. Almost as amazingly incredible as E=mc^2 (which is rather physics than mathematics of course). But as you write, "beauty" is something different for everybody.

People did not invent Complex numbers, they were "discovered"...
