As mathematicians Roger Cotes, René Descartes – who coined the term “imaginary number” – and others have observed, complex numbers make seemingly impossible integrals easy to solve and ...

When you add imaginary numbers and real numbers, the two form complex numbers, which enable physicists to write out quantum equations in simple terms. But whether quantum theory needs these ...

Among the many drastic changes it brought, it was the first theory phrased in terms of complex numbers. Invented by mathematicians centuries ago, complex numbers are made of a real and imaginary part.

But it’s also literally complex … by which I mean it’s built upon a fundamental set of numbers called complex numbers. Wait, yet another type of number? Yep! You know all about real numbers ...
