Before I get started, I feel that I should warn you that this video is VERY fast and dense with high level physics. I basically go through the physics as if you were students in an advanced physics course on Electricity and Magnetism at an elite university. I am not saying that to discourage anyone …

by Kathy Joseph I just finished a video on a history of the quaternions and a biography of their inventor, William Rowan Hamilton. In it, I stated, I hope pretty convincingly, that the basic features of vector algebra ALL came from Hamilton: the scalar, the vector, the dot product (or, at least the negative of …

This video started because I was working on …
