Complex number terminology is important in electrical engineering to distinguish a purely imaginary quantity, like the impedance of an ideal inductor, jωL, from the reactance of the inductor ωL.

Have you ever sat in a math classroom and wondered, “When will I ever use this?” You might have asked yourself this question when you first encountered “imaginary” numbers, and with good reason: What ...

An international team of researchers shows through a concrete theoretical experiment that the prediction by standard complex quantum theory cannot be expressed by its real counterpart and ratifies its ...
