-- "imaginary" numbers (e.g, the square root of minus one) are not real --

As a matter of vernacular, that is correct. A complex number has a real part and an imaginary part, and the two parts are in fact distinctly different.

Yes, they are not “real numbers”—in a technical sense.

However, the use of imaginary and complex numbers is consequential for certain real-world problems—as in engineering and physics. MIT and others teach about them.

So the “Science March” and Bill Nye lose again!!!!
