Noooooooo!!! Not any kind of number!

(Okay, imaginary numbers are kind of cool, but in high school I was really dogmatic and knee-jerk in my dislike of them.)
(And I still don't understand how *imaginary* numbers work in *real* application.)

Sir, it's not an offence to let your cat eat your bacon. Okay? And we don't arrest cats, I'm very sorry.

They're very useful in electronics.

I'm with Steph WRT the practical applications-- if it is imaginary and not real, how does it help us make a curve in real life? Or what have you...

I don't remember very well. I think you can use them to introduce a new dimension to a calculation. I believe one example is introducing phase into the math of AC electrical circuits.

if it is imaginary and not real
It's still a number, it's just not in the set of real numbers so it got tagged with a misleading name. Some people, I'm not saying who, are bigoted against numbers that aren't in the real set.
