PART ONE : Reading.
Take your time watch this video first.
Now read the following passage carefully then do the tasks below.
 In the ninth century the Muslims became the chief standard-bearers of science and philosophy.  of Muslim science lasted for about two centuries, from 900 AD to 1100 AD. The world owes a great depth of gratitude to the Muslim caliphs for their support for learning during this period.
The Muslims made important contributions to mathematics. The most outstanding work in Arabic in this field was probably the “arithmetic” of the Persian Al-Khawarismi (ninth century). In this treatise the author introduced a striking innovation; the number system that we use today and that we call the “Arabic Numerals” (0123456789). Al-Khawarismi also wrote a treatise entitled “On Algebra”. In was based to a certain extent on Hindu sources.
The Muslims were greatly interested in astronomy. The caliph Al-Ma’mun built a splendid observatory in Baghdad in the year 829, and his astronomers made regular observations of the heavens. One of them was Al-Battani (?? - 929) who revised many false notions in Ptolemy’s book “Great Composition” which was translated into Arabic.
There were also great physicists among the Muslim scientists. Al-Hazen (AbûʿAlî al-Ḥasan ibn al-Ḥasan ibn al-Haytham) of Basra (about 965 AD – 1038 AD) is the most famous one. His chief works were the “Treasury of Optics” and “On the Burning Sphere” in which he worked out the laws of reflection.
