Mathematic

Mathematics in medieval Islam or sometimes referred to as Islamic mathematics is a term used in the history of mathematics that refers to the mathematics developed in the Islamic world between 622 and 1600, in the part of the world where Islam was the dominant religious. Islamic science and mathematics flourished under the Islamic caliphate (also known as the Islamic Empire) established across the Middle East, Central Asia, North Africa, Sicily, the Iberian Peninsula, and in parts of France and India in the 8th century. The center of Islamic mathematics was located in Persia (including eastern part of present-day Iraq) , but at its greatest extent stretched from North Africa and Spain in the west and to India in the east.While most scientists in this period were Muslims and Arabic was the dominant language—much like Latin in Medieval Europe, Arabic was used as the written language of scholars throughout the Islamic world at the time—contributions were made by people of different ethnic groups (Arabs, Persians, Berbers, Moors, Turks) and sometimes different religions (Muslims, Christians, Jews, Sabians, Zoroastrians, irreligious).

The Taj Mahal, Agra India

In 1631, Shah Jahan, emperor during the Mughal empire's period of greatest prosperity, was griefstricken when his third wife, Mumtaz Mahal, died during the birth of their fourteenth child, Gauhara Begum. In her dying breath, Mumtaz Mahal urged Shah Jahan to build a mausoleum for her that the world has never seen before. Shah Jahan granted his wife's wish, and construction of the Taj Mahal began in 1632, one year after her death. The court chronicles of Shah Jahan's grief illustrates the love story traditionally held as an inspiration for Taj Mahal. The construction of Taj Mahal begun soon after Mumtaz's death with the principal mausoleum completed in 1648. The surrounding buildings and garden were finished five years later. Emperor Shah Jahan himself described the Taj in these words: Should guilty seek asylum here,

Like one pardoned, he becomes free from sin.
Should a sinner make his way to this mansion,
All his past sins are to be washed away.
The sight of this mansion creates sorrowing sighs;
And the sun and the moon shed tears from their eyes.
In this world this edifice has been made;
To display thereby the creator's glory.

The Taj Mahal incorporates and expands on design traditions of Persian and earlier Mughal architecture. Specific inspiration came from successful Timurid and Mughal buildings including the Gur-e Amir (the tomb of Timur, progenitor of the Mughal dynasty, in Samarkand), Humayun's Tomb, Itmad-Ud-Daulah's Tomb (sometimes called the Baby Taj), and Shah Jahan's own Jama Masjid in Delhi. While earlier Mughal buildings were primarily constructed of red sandstone, Shah Jahan promoted the use of white marble inlaid with semi-precious stones, and buildings under his patronage reached new levels of refinement.

The Suleyman Mosque, Turkey

The Süleymaniye Mosque was built on the order of Sultan Suleiman I (Suleiman the Magnificent) and was constructed by the great Ottoman architect Mimar Sinan. The construction work began in 1550 and the mosque was finished in 1557.

Sinan considered the design to be an architectural counterpoint to the Byzantine Hagia Sophia. The Hagia Sophia, converted into a mosque under Mehmed II, served as a model to many Ottoman mosques in Istanbul. However, Sinan's Süleymaniye is a more symmetrical, rationalized and light-filled interpretation of earlier Ottoman precedents, as well as the Hagia Sophia. It is possible that dialogue between Italy and Istanbul contributed to Sinan's enthusiasm for symmetrical and rational forms, as promoted by writers like Alberti.

The design of the Süleymaniye also plays on Suleyman's self-conscious representation of himself as a 'second Solomon.' It references the Dome of the Rock, which was built on the site of the Temple of Solomon, as well as Justinian's boast upon the completion of the Hagia Sophia: "Solomon, I have surpassed thee!" The Süleymaniye, similar in magnificence to the preceding structures, asserts Suleyman's historical importance. The structure is nevertheless smaller in size than its older archetype, the Hagia Sophia.
The Süleymaniye was ravaged by a fire in 1660 and was restored by Sultan Mehmed IV. Part of the dome collapsed again during the earthquake of 1766. Subsequent repairs damaged what was left of the original decoration of Sinan (recent cleaning has shown that Sinan experimented first with blue, before turning red the dominant color of the dome). The mosque was restored again in the middle of the 19th century by the Swiss-Italian architect brothers Gaspare and Giuseppe Fossati. In a botched attempt to restore it to its supposed original glory, the dome and the semi-domes were painted in an Ottoman baroque style. During the recent cleaning the original design was faithfully restored.

During World War I the courtyard was used as a weapons depot and when some of the ammunition ignited the mosque suffered another fire. Not until 1956 was it fully restored again.

The Alhambra, Spain

Completed towards the end of Muslim rule in Spain by Yusuf I (1333-1353) and Muhammed V, Sultan of Granada (1353-1391), the Alhambra is a reflection of the culture of the last days of the Nasrid emirate of Granada. It is a place where artists and intellectuals had taken refuge as Christian Spain won victories over Al Andalus. The Alhambra mixes natural elements with man-made ones, and is a testament to the skill of Muslim craftsmen of that time.

The literal translation of Alhambra "red fortress" derives from the colour of the red clay of the surroundings of which the fort is made. The buildings of the Alhambra were originally whitewashed; however, the buildings now seen today are reddish.

The first reference to the Qal’at al Hamra was during the battles between the Arabs and the Muladies during the rule of the ‘Abdullah ibn Muhammad (r. 888-912). In one particularly fierce and bloody skirmish, the Muladies soundly defeated the Arabs, who were then forced to take shelter in a primitive red castle located in the province of Elvira, presently located in Granada. According to surviving documents from the era, the red castle was quite small, and its walls were not capable of deterring an army intent on conquering. The castle was then largely ignored until the eleventh century, when its ruins were renovated and rebuilt by Samuel ibn Naghralla, vizier to the King Bādīs of the Zirid Dynasty, in an attempt to preserve the small Jewish settlement also located on the Sabikah hill. However, evidence from Arab texts indicates that the fortress was easily penetrated and that the actual Alhambra that survives today was built during the Nasrid Dynasty.

Ibn Nasr, the founder of the Nasrid Dynasty, was forced to flee to Jaén in order to avoid persecution by King Ferdinand and his supporters during attempts to rid Spain of Moorish Dominion. After retreating to Granada, Ibn-Nasr took up residence at the Palace of Bādis in the Alhambra. A few months later, he embarked on the construction of a new Alhambra fit for the residence of a king. According to an Arab manuscript published as the Anónimo de Granada y Copenhague, "This year 1238 Abdallah ibn al-Ahmar climbed to the place called "the Alhambra" inspected it, laid out the foundations of a castle and left someone in charge of its construction…" The design included plans for six palaces, five of which were grouped in the northeast quadrant forming a royal quarter, two circuit towers, and numerous bathhouses. During the reign of the Nasrid Dynasty, the Alhambra was transformed into a palatine city complete with an irrigation system composed of acequias for the gardens of the Generalife located outside the fortress. Previously, the old Alhambra structure had been dependent upon rainwater collected from a cistern and from what could be brought up from the Albaicín. The creation of the Sultan's Canal solidified the identity of the Alhambra as a palace-city rather than a defensive and ascetic structure.

The Muslim rulers lost Granada and Alhambra in 1492 without the fortress itself being attacked when King Ferdinand II of Aragon and Queen Isabella of Castile took the surrounding region with overwhelming numbers.
