The 'invention' of complex numbers isn't that old and people still find it hard to believe that they aren't just made up nonsense!
"A complex number is a number that can be put in the form a + bi, where a and b are real numbers and i is called the imaginary unit, where i2 = −1.[1] In this expression, a is called the real part and b the imaginary part of the complex number."
