BaalChatzaf Posted March 16, 2009 Share Posted March 16, 2009 (edited) GS:Grrr I still detest imaginary numbers, I attempted to understand it semantically which did not work at 13.What is your problem. The imaginary numbers (so-called) are what you have to add to the reals to make all polynomials with real co-efficient have roots. The complex field is the algebraic closure of the real polynomial ring. What is detestable about that? If that is too rare for you consider the set of matrices:- ............-| a, b.......|| -b, a......|_............._ where a and b are real. Algebraically they form a field in which the polynomial x^2 + 1 = 0 has a root. If I recall correctly, you are a master of statistics. I cannot comprehend why you have this difficulty.
