"Square root of negative one? You’re mad."

"Wait a minute..."

"No, listen, that just doesn’t make any sense whatsoever. I know you do mathematics and all, but you can’t do the square root of a negative number. You multiply two positive numbers together, you get a positive. You multiply two negative numbers together, you get a positive. So there’s NO WAY you can have the square root of a negative number. Am I right? What are you thinking?"

"Look, it’s complex..."

"No it’s not, you’re just wrong. Not complex at all, it’s pretty damned simple in fact."

"No, you idiot. Complex numbers."

"What?"

"Complex numbers. Look, there are times in mathematics and physics when it’s really useful to have the concept of the square root of a negative number, so we use this mathematical device we call an imaginary number."

"Okay, right about now, I’m imagining you stopping talking..."

"No, seriously... you define a letter i as being the square root of negative one and call it the imaginary part of a complex number. And then it also has a real part. Or they use j sometimes in physics... but it’s the same thing."

"Ohh, you’re serious. So... I get it, hey, that’s pretty neat. My coolness is i which you use to represent something imaginary... HEY!!!"
