Imaginary numbers, which can be combined with real numbers to form complex numbers, are numbers that were thought not to have any sort of analogue in daily life.

A real quantum theory, with no imaginary numbers, would predict different results than standard quantum physics, allowing the experiment to distinguish which one is correct.

Marcus du Sautoy explores the origins and practical uses of imaginary numbers. Relevant for teaching Maths at KS4 and GCSE in England, Wales and Northern Ireland and National 4/5 or Higher in ...

To test how important imaginary numbers were in describing reality, the researchers used an updated version of the Bell test, an experiment which relies on quantum entanglement.

Malcontent Wes popped into the comments of our recent post on the mathematical improbability of vampires with a link to a blog post with a great math-vampire analogy: vampires are the imaginary ...

Last month, we showed how all points on a two-dimensional plane could be assigned unique complex numbers whose real and imaginary parts indicated their horizontal and vertical distances from the ...

A general solution to the cubic equation was long considered impossible, until we gave up the requirement that math reflect reality.

If you know the instantaneous voltage across the resistor, you can derive the current and you can find the power–how much work that electricity will do.
