The Imaginary Number

Episode four of Five Numbers, the BBC radio series presented by Simon Singh.

The imaginary number takes mathematics to another dimension. It was discovered in sixteenth century Italy at a time when being a mathematician was akin to being a modern day rock star, when there was 'nuff respect' to be had from solving a particularly 'wicked' equation. And the wicked equation of the day went like this: "If the square root of 1 is both 1 and -1, then what is the square root of -1?"
