a: Quaternion ~
b: the plague
What:
"Quaternion is like the plague: it's fun at first but then all your descendants hate your guts for it. They're like complex numbers only they have three orthogonal imaginary axes instead of just one, and the group of unit quaternions is isomorphic to the R3 rotation group for whatever reason (quaternion multiplication = rotation composition, quaternion conjugation = rotation inversion, etc)."
