Document 3: History of science: In Babylonian astronomy, records of the motions of the stars, planets, and the moon are left on thousands of clay tablets created by scribes. Even today, astronomical periods identified by Mesopotamian proto-scientists are still widely used in Western calendars such as the solar year and the lunar month. Using these data they developed arithmetical methods to compute the changing length of daylight in the course of the year and to predict the appearances and disappearances of the Moon and planets and eclipses of the Sun and Moon. Only a few astronomers' names are known, such as that of Kidinnu, a Chaldean astronomer and mathematician. Kiddinu's value for the solar year is in use for today's calendars. Babylonian astronomy was "the first and highly successful attempt at giving a refined mathematical description of astronomical phenomena." According to the historian A. Aaboe, "all subsequent varieties of scientific astronomy, in the Hellenistic world, in India, in Islam, and in the West—if not indeed all subsequent endeavour in the exact sciences—depend upon Babylonian astronomy in decisive and fundamental ways."
Document 4: Muslim world: The Islamic Golden Age coincided with the Middle Ages in the Muslim world, starting with the rise of Islam and establishment of the first Islamic state in 622. The end of the age is variously given as 1258 with the Mongolian Sack of Baghdad, or 1492 with the completion of the Christian Reconquista of the Emirate of Granada in Al-Andalus, Iberian Peninsula. During the reign of the Abbasid caliph Harun ar-Rashid (786 to 809), the legendary House of Wisdom was inaugurated in Baghdad where scholars from various parts of the world sought to translate and gather all the known world's knowledge into Arabic. The Abbasids were influenced by the Quranic injunctions and hadiths, such as "the ink of a scholar is more holy than the blood of a martyr," that stressed the value of knowledge. The major Islamic capital cities of Baghdad, Cairo, and Córdoba became the main intellectual centers for science, philosophy, medicine, and education. During this period, the Muslim world was a collection of cultures; they drew together and advanced the knowledge gained from the ancient Greek, Roman, Persian, Chinese, Indian, Egyptian, and Phoenician civilizations.
Document 5: History of mathematics: Babylonian mathematics refers to any mathematics of the peoples of Mesopotamia (modern Iraq) from the days of the early Sumerians through the Hellenistic period almost to the dawn of Christianity. The majority of Babylonian mathematical work comes from two widely separated periods: The first few hundred years of the second millennium BC (Old Babylonian period), and the last few centuries of the first millennium BC (Seleucid period). It is named Babylonian mathematics due to the central role of Babylon as a place of study. Later under the Arab Empire, Mesopotamia, especially Baghdad, once again became an important center of study for Islamic mathematics.

Document 11: Madrasa: From around 750, during the Abbasid Caliphate, women “became renowned for their brains as well as their beauty”. In particular, many well known women of the time were trained from childhood in music, dancing and poetry. Mahbuba was one of these. Another feminine figure to be remembered for her achievements was Tawaddud, "a slave girl who was said to have been bought at great cost by Hārūn al-Rashīd because she had passed her examinations by the most eminent scholars in astronomy, medicine, law, philosophy, music, history, Arabic grammar, literature, theology and chess". Moreover, among the most prominent feminine figures was Shuhda who was known as "the Scholar" or "the Pride of Women" during the 12th century in Baghdad. Despite the recognition of women's aptitudes during the Abbasid dynasty, all these came to an end in Iraq with the sack of Baghdad in 1258.

Document 14: History of science: From their beginnings in Sumer (now Iraq) around 3500 BC, the Mesopotamian people began to attempt to record some observations of the world with numerical data. But their observations and measurements were seemingly taken for purposes other than for elucidating scientific laws. A concrete instance of Pythagoras' law was recorded, as early as the 18th century BC: the Mesopotamian cuneiform tablet Plimpton 322 records a number of Pythagorean triplets (3,4,5) (5,12,13). ..., dated 1900 BC, possibly millennia before Pythagoras,  but an abstract formulation of the Pythagorean theorem was not.
Document 15: History of science: In mathematics, the Persian mathematician Muhammad ibn Musa al-Khwarizmi gave his name to the concept of the algorithm, while the term algebra is derived from al-jabr, the beginning of the title of one of his publications. What is now known as Arabic numerals originally came from India, but Muslim mathematicians did make several refinements to the number system, such as the introduction of decimal point notation. Sabian mathematician Al-Battani (850-929) contributed to astronomy and mathematics, while Persian scholar Al-Razi contributed to chemistry and medicine.
