DURHAM, N.C. – Computer engineers at Duke University have demonstrated that using complex numbers—numbers with both real and imaginary components—can play an integral part in securing artificial ...

To a nonmathematician, having the letter "i" represent a number that does not quite exist and is "imaginary" can be hard to wrap your head around. If you open your mind to this way of thinking, ...

In this video, we explore the role of imaginary numbers—numbers involving √−1—in modern physics. Initially seen as abstract, ...

Imaginary numbers might seem like unicorns and goblins — interesting but irrelevant to reality. But for describing matter at its roots, imaginary numbers turn out to be essential. They seem to be ...

In this video tutorial, I show you how to divide complex numbers. Since complex numbers have an imaginary part which we cannot divide into other numbers, we rewrite the expression by multiplying by i ...
