Today, complex numbers have such widespread practical use—from electrical engineering to aeronautics—that few people would expect the story behind them to be filled with adventure and enigma. In An Imaginary Tale, Paul Nahin tells the 2000-year history of one of mathematics' most elusive numbers, the square root of minus one, also known as i. He re-creates the baffling mathematical problems that conjured it, and the colorful cast of characters who tried to solve them. Weaving together entertaining historical facts and mathematical discussions, An Imaginary Tale is an engaging history of one of the most evasive and pervasive "numbers" in all of mathematics.
