So I thank you! permalink fedilink source parent hideshow 1 child comment replies: [–] Klear@sh.itjust.works 3 points 1 year ago Quaternions are the closest we get to lovecraftian horror in real life. Four dimensional and mostly imaginary, they were carved into a stone bridge by a crazy mathematician in a fit of madness, Lord Kelvin called them "unmixed evil", and the Mad Hatter from Alice may have been inspired by them. Also they have been a curiosity at best for a long time, despite the efforts of a secret Quaternion Society, but they suddenly blew up in usefulness in modern times as they happen to be an easy and fast way for computers to describe rotations in 3D space, so they're everywhere. Yeah, lovecraftian as shit. permalink fedilink source parent [–] codexarcanum@lemmy.dbzer0.com 14 points 1 year ago* (2 children) It gets worse actually. You can define a number system using any power of 2 amount of i-like units in a similar relationship to quaternions using the Cayley-Dickson construction Fascinatingly, you lose some property of the algebra at each step. Quaternions aren't commutative: ABC != CBA. Octonians aren't associative: (AB)C != A(BC). Once you get into 16 i's with subscripts, it really gets crazy. (Also, I just got the joke.
