Imaginary numbers may seem abstract or even whimsical at first, but they are far from being mere mathematical curiosities. In fact, they are a natural extension of our number system, leading to a ...

Imaginary numbers, labeled with units of i (where, for instance, (2 i) 2 = -4), gradually became fixtures in the abstract realm of mathematics.

The bi component is responsible for the specific features of complex numbers. The key role here is played by the imaginary number i, i.e. the square root of -1.

There has long been a mystery when calculating how an incoming light wave scatters off an object and becomes a modified, ...

The imaginary part is a multiple of the number i, “the square root of minus one”, which is defined by the equation i ² = –1.

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 ...
