Strange, long-forgotten numbers called quaternions are undergoing a revival in computer graphics, math, and physics.

From electrical engineering to quantum mechanics, imaginary numbers are integral in solving complex equations and models that would otherwise be impossible to approach with only real numbers.

The 19th-century discovery of numbers called “quaternions” gave mathematicians a way to describe rotations in space, forever changing physics and math.

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 ...

What do you get when you put a real and an imaginary number together? A complex number. No, not a complicated number (although it is kind of complicated). We’re talking about an entirely new set ...

The Imaginary Number Simon Singh's Numbers Five Numbers The imaginary number takes mathematics to another dimension. If the square root of +1 is both +1 and -1, then what is the square root of -1?

Puzzle solvers used “imaginary” numbers to solve a real world problem: finding long-lost treasure.

Imaginary numbers are a solution to a very real problem, according to a new study published in Scientific Reports. Two physicists at Argonne National Laboratory offered a way to mathematically ...

Mind over math: Children learn to use ‘imaginary abacus’ Students of the ‘Mind Mathlon 2014’ display the benefits of a unique calculating technique.

Imaginary numbers were once seen as impossible, but they became essential tools in solving real mathematical problems.
