No, I don’t mean about whether or not Planet X has begun cutting a destructive swath across our solar system.

(Note: I lied. This will be my first “neural dump.” I began writing about Euler’s Formula, but felt what follows was worthy of its own post and a better foundation for what will follow when I tackle Euler.) Complex numbers arose from the fact that there is no solution for in the equation in , …
