Comments by "David Terr" (@dcterr1) on "How Imaginary Numbers Were Invented" video.

When I first learned about imaginary numbers, I thought to myself, "No way! There can't be any such numbers!" However, the more I learned about them, the more real they seemed. To me, it seems fitting that according to quantum theory, they are required to exist in the real world. Now what seems stranger to me is that we DON'T ordinarily observe imaginary numbers in real life.

@franzchopin4274 This is true, but who would have ever come up with this on their own, especially as early as the 15th century? The history behind the discovery of complex numbers makes a lot more sense, since many mathematicians were trying to solve various cubic and quartic equations and they needed complex numbers in order to do so.
