Re: “And, finally, Imaginary Numbers.”
The weirdness continues. Have you ever heard that 'some infinities are bigger than others?' Yup. We aren't supposed to grok this stuff. We're just supposed to do it.

Fiz > FWIW, it would probably be helpful if you have at least a little idea what a "Complex number" is


Ahhhhh . . .
The square root of negative one. Usually written as '1 + i' or '5 + 7i' or even such strange things as '2.379 - 4.73i'

I STILL remember being told early in my Mathematics education "You can NOT take the square root of a negative number!" . . . And then learning that when one takes the square root - it should be 'Plus or Minus' the square root. And, finally, Imaginary Numbers.

And Vectors. Vectors and imaginary number arithmetic go hand in hand.

Interesting thing about Python (Programming) . . It seems to like complex numbers. I wrote some code to implement the quadratic equation . . and it gave me the answer - complex numbers and all.
