Thats good. Thanks. See? - yer doing your part in breaking down these stigma's flating around. Contributed to Space Science? How about invented the concept of modern astronomy? Invented advanced math? Who, when, and what exactally? If you're actually curious, not just trolling for an argument, you might find some of the following comments helpful: (from www.enhg.org) Development of Arab Scientific Interest The Arabs once ruled an empire that stretched from central Asia to Spain. This empire reached its zenith between the eighth and thirteenth centuries AD. Arab scholars of that period knew more about science and the arts than any other contemporary peoples. They also translated many classical (Greco-Roman) works of literature and science. In fact generally speaking the Muslims were very interested in books and learning. Rhazes (al Razi-C. ninth century), Vienna (Ibn Sina-c. tenth century) and Averroes (1126-1198) were among the best known of Muslim philosophers. They studied the great Greek writers, particularly Plato and Aristotle. Their goal seems to have been (perhaps rather surprisingly) to try to find ways to reconcile the ideas of the ancient Greeks with the teachings of Islam. Consequently, universities were established in the leading Muslim cities of Baghdad, Damascus, Jerusalem, Alexandria, Cairo and Cordoba. Further, the book business flourished. In universities, palaces and the homes of wealthy merchants could be found large and impressive libraries. By 1250 AD the most valuable material in Islamic libraries had become available to European scholars in translation. The latter point was of great historical importance; eventually much of the scientific knowledge that the Muslims had gathered from the ancient classical world and from India was passed to the west, through Spain and southern Italy, around the time of the Crusades. At that time most European scholars realized the tremendous scientific and technological superiority of the Islamic world. And eagerly sought translations of Muslim works. Thus these Greek and Arab writings that flowed into Europe, especially after the beginning of the twelfth century, made up a rich legacy of scientific and philosophical knowledge. For example, Arabic (Hindi) numerals and the zero symbol made possible a decimal system of computation. Also, Euclidean geometry, together with algebra and trigonometry from the Arab world, greatly increased the scope and accuracy of mathematics, especially useful for later astronomical applications during and after the Renaissance. This transfer of information occurred just in time, for from about 1350 onwards, the Mongols in the east and the Christians in Spain began systematically to destroy Islamic books in a wholesale manner, as part of their anti-Muslim wave of feeling at that time Fortunately, a large number of Islamic books survived in Egypt, Persia and India, from where most of our knowledge of Muslim civilization has originated. As a result, every present-day intellectual disciple owes a debt to the scientific heritage of Islam Arab Astronomy and Navigation Astronomy Muslim scholars made significant contributions towards the development of many 'modern' sciences, such as physics, chemistry, medicine, mathematics and astronomy. They were particularly interested in the latter. Using the work of the second century Greek astronomer Ptolemy as a basis, Muslim thinkers greatly increased man's knowledge of astronomy. Indeed, during the Middle Ages, when European science underwent a decline, it was the Arabs who preserved the astronomical heritage. In some respects this achievement may have been inevitable, since knowledge of the stars was essential for navigational purposes and for telling the times of prayers and religious festivals. In other words, being adventurous traders and mariners and temporally precise worshippers, the Arabs needed to study astronomy other than for its purely scientific interest, though undoubtedly such an interest existed. Consequently they constructed many observatories and improved certain measuring instruments such as the astrolabe for determining and recording the positions and movements of celestial bodies. Foremost amongst early Arab scientists was al Khawarzimi, who lived in Baghdad during the ninth century. His work was mainly concerned with astronomy and mathematics. In fact, his mathematical treatise was the first to employ what westerners term 'Arabic numerals' (which were really borrowed from the Indians, as explained earlier. Although it seems most likely that the Indians invented the zero symbol or cipher ('sifr' means empty in Arabic), al Khwarzimi is attributed with greatly developing its use n mathematics to simplify multiplication and division. He also gave a systematic account of algebra and geometry, for use in solving practical astronomical and navigational problems. Other notable Arab astronomers were al Battam (d. 929), al Zarquli (d. 1087) and Omar al Khayyami (d. 1123). The latter was a Persian mathematician who devised a very accurate calendar based on astronomical observations. It was reputed to have been more accurate than the Gregorian one we use today, with an error factor of only one day in 3770, rather than the Gregorian's one in 33303. Incidentally, the mathematics used for astronomical calculations by the Arabs involved the use of degrees and minutes of arc-first developed by the Sumerians, and later developed extensively by the Babylonians, millennia earlier. The direct expansion and inclusion of this system into Euclidean geometry is the main reason why we measure angles in degrees, minutes and seconds nowadays (not to mention basing our system of measuring time upon it also). Arab interest in astronomy was also continued in Moghul India, where massive observatories were built in Jaipur, for example. It is interesting to consider that some modern historians think that the writings of the great Copernicus (who was the first westerner to propose an heliocentric planetary system) show much that could be attributable to these early Muslim astronomers. Navigation When the first Portuguese navigators, like Vasco da Gama, sailed along the East African coast and around the Arabian Peninsula they encountered a well-established Arab seafaring tradition, utilizing an advanced navigational science dating from the eighth century. Techniques used were basically simple, but never the less by the eleventh century Arab mariners had adapted the Chinese discovery of the magnetic properties of lodestone for use as a compass at sea. Earlier methods had relied on steering by Polaris, the 'North' star, and 'Kamal', a kind of simple astrolabe used to reckon relative latitude. In fact, it is believed that Europeans first acquired a knowledge of the magnetic compass and the astrolabe (later to become the sextant) from Muslim sailors. The renowned Arab navigator Shihab al Ahmed bin Majid al Najdi (c.1500), at the height of Arab navigational prowess, wrote a masterpiece entitled "the Book of Profitable Things concerning the First Principles and Rules of Navigation" which featured much astronomical observational data, amongst other things nautical. Part of the legacy of this period include the fact that many of the brightest stars still bear Arabic names, allocated to them by Arab astronomers and navigators, for example Betelgeuse, Deneb, Aldebaran and Altair. These names, along with numerous other facets of Arab scientific nomenclature and mathematics, passed into Europe during the Renaissance. However, this period, marked by the 'collision' of two great maritime powers - the European and the Arabian - was the beginning of the era of European ascendancy and the decline of Arab commercial dominance in Middle Eastern and Oriental seas. |
