Solving the Cubic Equation and the Discovery of Complex Numbers

Incidentally, two of the ancient “unsolvable problems in geometry”, doubling the cube and trisecting an angle, are equivalent to solving a cubic equation.


Ok. I learned something new today. At this late date in my life, I hope I might yet grasp the Schrödinger wave equation. /:

I just started watching this. Yoiks, and away!

Interesting history lesson. And I appreciate the simple linkage between algebra and geometry.
