M302: Quaternions: Super Vectors in Splash Spring 15 (Apr. 25, 2015)
Quaternions, $$\mathbb{H}$$, are the next step up from complex numbers. Complex numbers are made from real numbers and a number i such that $$i^2+1=0$$. However, in quaternions, we have three such numbers i, j, and k such that $$i^2=j^2=k^2=-1$$. Come explore some of the history behind the subject and figure out why the heck the cross product makes sense (like really, did anyone actually understand that?).
