ε, the base of the dual numbers.
It’s a nonzero hypercomplex number that squares to zero, enabling automatic differentiation.
Came here to say this, but since it’s already here, I’ll throw in a bonus mind-melting fact: ε itself has no square root in the dual numbers.
j = √-1

Set phasors to “confuse”
So complex or quaternion I imagine? ‘i’ it is!
√-4 = 2
It’s all fun and games until someone loses an i.
i=sqrt(-1) is nice, but im hoping someone finds a use for the number x where |x| = -1 or some nonsense like that because it looks fun to mess with

I always like seeing π.
