Top 5 facts about Imaginary Math (Synopsis)

There is not enough love and goodness in the world to permit giving any of it away to imaginary beings.” -Friedrich Nietzsche

You know that the square root of -1 is “i”, an imaginary number. But did you know any of these?

For classical (Newtonian) mechanics, as well as electromagnetism, it’s sufficient to use real mathematics to describe it fully, if not always ideal. But to take care of Einstein’s relativity (and spacetime in particular), as well as quantum mechanics, you need to go beyond the real numbers and into the complex plane, which includes imaginary numbers as well!
