QUES: Translation of material into Arabic expanded after the creation of Arabic script in the 5th century, and gained great importance with the rise of Islam and Islamic empires. Arab translation initially focused primarily on politics, rendering Persian, Greek, even Chinese and Indic diplomatic materials into Arabic. It later focused on translating classical Greek and Persian works, as well as some Chinese and Indian texts, into Arabic for scholarly study at major Islamic learning centers, such as the Al-Karaouine (Fes, Morocco), Al-Azhar (Cairo, Egypt), and the Al-Nizamiyya of Baghdad. In terms of theory, Arabic translation drew heavily on earlier Near Eastern traditions as well as more contemporary Greek and Persian traditions.

QUES: Energy gives rise to weight when it is trapped in a system with zero momentum, where it can be weighed. It is also equivalent to mass, and this mass is always associated with it. Mass is also equivalent to a certain amount of energy, and likewise always appears associated with it, as described in mass-energy equivalence. The formula E = mc, derived by Albert Einstein (1905) quantifies the relationship between rest-mass and rest-energy within the concept of special relativity. In different theoretical frameworks, similar formulas were derived by J. J. Thomson (1881), Henri Poincare (1900), Friedrich Hasenohrl (1904) and others (see Mass-energy equivalence#History for further information).
