Numberphile's explanation of Quaternions is the simplest I have seen so far: [VIDEO] Quaternions are very important to know if you are doing any kind of 3D math. For instance, game programming or SLAM for robotics.

Kalid - also your explanation of complex numbers is absolutely amazing. Sure I could manipulate them by memorizing rules, but I never really knew what they meant or why they were important. I also love the Numberphile explanation of quaternions (building up from real to complex numbers, etc.) - [VIDEO] -Sujan

This video might be easier to grasp: Fantastic Quaternions - Numberphile [VIDEO] It also helped me to have a use-case in mind —- a motivation. Like maybe using the accelerometer/compasss in your phone to perform image stabilization or AR.
