There is a difference between science of scholors and popular science.I dont want to get into the detals of that.As far as telling you who Razi is here is the refernence
because Razis fundamental contribution,the Princeton University put up his image on the glass window of the Chapel to commemorate the contributions of Al-Razi to the science of medicine for the whole world
