In the first article when I mentioned quaternions, someone sent me mail (that unfortunately got trashed before I had to respond to it)_ asking how i^2 = -1, j^2 = -1, and k^2 = -1 but i != j != k. It does in exactly the same way that 1^2 = 1 and -1^2 = 1 but 1 != -1. I apologize for this, but I wanted to respond. John Hobson AT&T Bell Labs--Naperville, IL ihnp4!ihuxq!amigo2
