## what does “1ijk” stand for?

A quaternion is a type of number, like a real number $\pi \in \mathbb{R}$ or a complex number $\sqrt{-1} \in \mathbb{C}$. The expression

$$-1 = ijk = i^2 = j^2 = k^2$$

describes the quaternions. These numbers have very nice properties and some cool history. For example:

[@QuantaMagazine](https://twitter.com/QuantaMagazine?ref_src=twsrc%5Etfw) wrote about octonions they decided to write about on quaternions - and they interviewed me! Did you know the "dot product" and "cross product" were originally two parts of a single thing, the quaternion product?


They appeal to me, although I cannot say I understand much about them. And given that the string $1ijk$ is short, memorable, and rarely taken as a username, I’ve taken it as my online moniker.
