exactly, thanks for the reply.
today quaternions are used in computer animation algorithms to describe motion & translation of 3D objects.
100 years ago, an irish mathmetician Hamilton invented quaternions and then Heaviside & Maxwell applied them to electrodynamics. in fact, if you read maxwell's treaty on electricity his famous "4 equations" (vector calculus) are actually more like 20, and they are in quaternion form!!
so why is this important?
quaternions are a higher order mathematics that takes into account the 2 lower forms (tensors & vectors). you can "read into" the equation more if you have a higher form of math. you might learn something startling, mostly forgotten and/or missed by today's leading electrodynamics experts... or not.
