As any algebra student is likely to ask a teacher, "Who ever uses complex numbers anyway?" The obvious answer, of course, is "math teachers." But that's just the beginning. Most scientists and ...

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 ...

The world of math is complex … in more ways than one. Sure, it’s full of complex ideas that are all tied up and packaged within beautiful and often times complex wrapping paper that is adorned with ...

Physicists from Heinrich Heine University Düsseldorf (HHU) have examined a fundamental property of quantum mechanics in collaboration with the German Aerospace Center (DLR). In an article published in ...

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 ...

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, ...

This worksheet on Complex Numbers serves as a nice introduction to Complex Numbers typically seen as Core Pure 1 Material. This worksheet does not feature topics seen in Core Pure 2 such as Roots of ...

As children, we all learn about numbers. We start with counting, followed by addition, subtraction, multiplication and division. But mathematicians know that the number system we study in school is ...

A differentiated worksheet/revision sheet resource for basic complex number operations, including adding, subtracting and multiplying. Designed for the new A-level specification. If the resource is ...

Physicists construct theories to describe nature. Let us explain it through an analogy with something that we can do in our everyday life, like going on a hike in the mountains. To avoid getting lost, ...
