PS - I'm not going to get carried into this research based debate, since I see no point in wasting my time doing it. There are some simpler issues which need answer. Why beat the bygone, when the present stares you and tells a very different story? Why not try to improve in today's time rather than keep worrying who lead in the ancient science and mathematics? And I'm saying this by keeping the Arab world in mind, since they have all sorts of problems with the West. these days.
