Khayyam
Ghiyāth al-Dīn Abū al-Fatḥ ʿUmar ibn Ibrāhīm Nīsābūrī (18 May 1048 – 4 December 1131), commonly known as Omar Khayyam ( fa, عمر خیّام), was a polymath, known for his contributions to mathematics, astronomy, philosophy, and Persian poetry. He was born in Nishapur, the initial capital of the Seljuk Empire. As a scholar, he was contemporary with the rule of the Seljuk dynasty around the time of the First Crusade. As a mathematician, he is most notable for his work on the classification and solution of cubic equations, where he provided geometric solutions by the intersection of conics. Khayyam also contributed to the understanding of the parallel axiom.Struik, D. (1958). "Omar Khayyam, mathematician". ''The Mathematics Teacher'', 51(4), 280–285. As an astronomer, he calculated the duration of the solar year with remarkable precision and accuracy, and designed the Jalali calendar, a solar calendar with a very precise 33-year intercalation cycle''The Cambri ...

Nishapur
Nishapur or officially Romanized as Neyshabur ( fa, ;Or also "نیشاپور" which is closer to its original and historic meaning though it is less commonly used by modern native Persian speakers. In Persian poetry, the name of this city is written and pronounced as "نِشابور" (without the usage of "پ" or "ب"). In modern times and among the general public and the Persian mass media, "نیشابور" is the most commonly used style of pronunciation and spelling of this city though "نیشاپور" is also correct. Nišâpur, Nişapur, Nīshābūr, or Neyshapur are also the other Romanizations of this city. from Middle Persian ''"New-Shapuhr"'', meaning: "The New City of Shapur", "The Fair Shapur", or "The Perfect built of Shapur") is the second-largest city of Razavi Khorasan Province in the Northeast of Iran.

Edward FitzGerald (poet)
Edward FitzGerald or Fitzgerald (31 March 180914 June 1883) was an English poet and writer. His most famous poem is the first and best-known English translation of ''The Rubaiyat of Omar Khayyam'', which has kept its reputation and popularity since the 1860s. Life Edward FitzGerald was born Edward Purcell at Bredfield House in Bredfield, some two miles north of Woodbridge, Suffolk, England, in 1809. In 1818, his father, John Purcell, assumed the name and arms of his wife's family, the FitzGeralds. His elder brother John used the surname Purcell-Fitzgerald from 1858. The change of family name occurred shortly after FitzGerald's mother inherited a second fortune. She had previously inherited over half a million pounds from an aunt, but in 1818, her father died and left her considerably more than that. The FitzGeralds were one of the wealthiest families in England. Edward FitzGerald later commented that all of his relatives were mad; further, that he was insane as well, but was a ...

Persian Poetry
Persian literature ( fa, ادبیات فارسی, Adabiyâte fârsi, ) comprises oral compositions and written texts in the Persian language and is one of the world's oldest literatures. It spans over two-and-a-half millennia. Its sources have been within Greater Iran including present-day Iran, Iraq, Afghanistan, the Caucasus, and Turkey, regions of Central Asia (such as Tajikistan) and South Asia where the Persian language has historically been either the native or official language. For example, Rumi, one of the best-loved Persian poets, born in Balkh (in modern-day Afghanistan) or Wakhsh (in modern-day Tajikistan), wrote in Persian and lived in Konya (in modern-day Turkey), at that time the capital of the Seljuks in Anatolia. The Ghaznavids conquered large territories in Central and South Asia and adopted Persian as their court language. There is thus Persian literature from Iran, Mesopotamia, Azerbaijan, the wider Caucasus, Turkey, Pakistan, Bangladesh, India, Tajikista ...

Mathematics In Medieval Islam
Mathematics during the Golden Age of Islam, especially during the 9th and 10th centuries, was built on Greek mathematics (Euclid, Archimedes, Apollonius of Perga, Apollonius) and Indian mathematics (Aryabhata, Brahmagupta). Important progress was made, such as full development of the decimal place-value system to include decimal fractions, the first systematised study of algebra, and advances in geometry and trigonometry. Arabic works played an important role in the transmission of mathematics to Europe during the 10th—12th centuries. Concepts Algebra The study of algebra, the name of which is derived from the Arabic language, Arabic word meaning completion or "reunion of broken parts", flourished during the Islamic golden age. Muhammad ibn Musa al-Khwarizmi, a Persian scholar in the House of Wisdom in Baghdad was the founder of algebra, is along with the Greek people, Greek mathematician Diophantus, known as the father of algebra. In his book ''The Compendious Book on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Persian Philosophy
Iranian philosophy (Persian: فلسفه ایرانی) or Persian philosophy can be traced back as far as to Old Iranian philosophical traditions and thoughts which originated in ancient Indo-Iranian roots and were considerably influenced by Zarathustra's teachings. According to the Oxford Dictionary of Philosophy, the chronology of the subject and science of philosophy starts with the Indo-Iranians, dating this event to 1500 BC. The Oxford dictionary also states, "Zarathustra's philosophy entered to influence Western tradition through Judaism, and therefore on Middle Platonism." Throughout Iranian history and due to remarkable political and social changes such as the Arab and Mongol invasions of Persia, a wide spectrum of schools of thoughts showed a variety of views on philosophical questions extending from Old Iranian and mainly Zoroastrianism-related traditions, to schools appearing in the late pre-Islamic era such as Manicheism and Mazdakism as well as various post-Islamic sc ...

Nizami Aruzi
Ahmad ibn Umar ibn Alī, known as Nizamī-i Arūzī-i Samarqandī ( fa, نظامی عروضی) and also Arudi ("The Prosodist"), was a Persian poet and prose writer who flourished between 1110 and 1161. He is particularly famous for his ''Chahar Maqala'' ("Four Discourses"), his only work to fully survive. While living in Samarqand, Abu’l-Rajaʾ Ahmad b. ʿAbd-Al-Ṣamad, a ''dehqan'' in Transoxiana, told Nezami of how the poet Rudaki was given compensation for his poem extolling the virtues of Samanid ''Amir'' Nasr b. Ahmad. Life A native of Samarqand in Transoxiana, his date of birth and death is uncertain. He was most likely born at the end of the 11th century. What is little known of his life can only be found in his book ''Chahar Maqala''. He spent most of his time in Khorasan and Transoxiana, and served as a court-poet to the Ghurids for 45 years. In 1110/1, he was at Samarqand, where he gathered material about the Persian poet Rudaki (d. 941). In 1112/3, he met Omar Khay ...

Mathematics
Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics with the major subdisciplines of number theory, algebra, geometry, and analysis, respectively. There is no general consensus among mathematicians about a common definition for their academic discipline. Most mathematical activity involves the discovery of properties of abstract objects and the use of pure reason to prove them. These objects consist of either abstractions from nature orin modern mathematicsentities that are stipulated to have certain properties, called axioms. A ''proof'' consists of a succession of applications of deductive rules to already established results. These results include previously proved theorems, axioms, andin case of abstraction from naturesome basic properties that are considered true starting points of ...

Saccheri
Giovanni Girolamo Saccheri (; 5 September 1667 – 25 October 1733) was an Italian Jesuit priest, scholastic philosopher, and mathematician. Saccheri was born in Sanremo. He entered the Jesuit order in 1685 and was ordained as a priest in 1694. He taught philosophy at the University of Turin from 1694 to 1697 and philosophy, theology and mathematics at the University of Pavia from 1697 until his death. He was a protégé of the mathematician Tommaso Ceva and published several works including ''Quaesita geometrica'' (1693), ''Logica demonstrativa'' (1697), and ''Neo-statica'' (1708). Geometrical work He is primarily known today for his last publication, in 1733 shortly before his death. Now considered an early exploration of non-Euclidean geometry, ''Euclides ab omni naevo vindicatus'' (''Euclid Freed of Every Flaw'') languished in obscurity until it was rediscovered by Eugenio Beltrami, in the mid-19th century. The intent of Saccheri's work was ostensibly to establish the vali ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
