At the installation of bernoui, his contemporaries dealt with the same problem as "Sind ibn Ali, Yuhani ibn Yusuf, Ahmad ibn al-Fadl, Al-Bukhari and Muhammad ibn Zakariy AR-Razi", identifying the specific weights of minerals and metals with the help of his tools, Beruu said, "we start with the heaviest metal, then move on to the lighter metal, so that the amount of waterbecause the amount of water corresponds to the volume of bodies."
