There is a difference between understanding and agreeing What gives you the right to call anyone a nonmathematician You were the first to imply this of me My suggestion to you is dont dish it out if you cant take it To call someone a nonmathematician when it is false is an attack on ones character I returned your favour Now if what you claim is true there were no real mathematicians until LeviCivita came along This smacks to me of Jewish superiority complex
