SCIENZA ARABA Moesgaard,thabit ibn qurra between Ptolemy and Copernicus a Analysis of http://www.dismec.unige.it/testi/cosmo/Theb.htm
Extractions: Matematico eccellente e medico apprezzato al suo tempo fu un celebre traduttore dal greco all'arabo, e revisionò i testi derivanti dal siriaco, essendo questa la sua lingua materna. Le fonti arabe non sono concordi nell'indicare l'anno della nascita. Originario di Harran, in Mesopotamia, era membro della setta dei Sabei, presso i quali si erano conservate vive le tradizioni ellenistiche. Questa regione era anche famosa per la costruzione degli astrolabi. In seguito a dissapori con i correligionari si trasferì a Bagdad su invito di Muhammad b. Musa b. Shakir, entrando nel circolo scientifico da lui fondato assieme ai suoi due fratelli. L'opera di Thabit b. Qurra si inserisce nel grande movimento scientifico che iniziò sotto l'impulso di al-Ma'mun che regnò dal 198/813 al 218/833. Sotto il suo regno furono costruiti due osservatori, uno a Damasco e l'altro a Bagdad e ampliò la famosa "Casa della sapienza" bayt al-hikma , un istituzione fondata sotto il regno di al-Mansur: era nello stesso tempo biblioteca generale, centro di ricerca e di traduzione dal siriaco o dal greco all'arabo. Accanto a questa istituzione operava nello stesso periodo il circolo fondato dai mecenati "fratelli Musa".

Extractions: "Dato ciò che abbiamo detto, è necessario che il movimento della sfera delle stelle fisse sia connesso a quello dell'orbita del sole, quanto alla leggera differenza che interviene tra il risultato che abbiamo trovato per lo spostamento dell'apogeo del sole, nel tempo che va dall'osservazione degli antichi alla nostra osservazione, essa deriva da un errore di osservazione. La prova di ciò risiede nel fatto che quando Tolomeo ha fatto la sintesi dei suoi risultati, ha menzionato che il movimento della sfera delle stelle fisse era di 1 grado per secolo,mentre noi abbiamo trovato che il movimento della sfera delle stelle fisse è di un grado e mezzo per secolo circa.". Questo passo è fondamentale perchè mostra come ben presto a Bagdad si mise a controllo i dati e i modelli di Tolomeo, mentre in Occidente si continuava a seguire l'astronomo greco, come Dante espressamente ancora riferisce nella Vita Nova e nel Convivio ,citando il compendio di Astronomia tolemaica di Al-Fargani, un astronomo della generazione precedente a Thabit Ibn Qurra. Per essere precisi la costante annuale di precessione trovata da Thabit è di 0;0,49,39, molto vicina alla misura di 50" per anno della tradizione sapienziale dell'antichità.

Extractions: Died: about 1160 Jabir ibn Aflah is often known by the Latinised form of his name, namely Geber. Although not he was not in the first rank of Arabic mathematicians, he is important in the development of mathematics since his works were translated into Latin, and so became available to European mathematicians, whereas the work of some of the top rank Arabic mathematicians such as Abu'l-Wafa were not translated into Latin. Very little information is available regarding Jabir ibn Aflah's life. That he came from Seville is known from two sources. Firstly he is described as "al-Ishbili" in manuscripts containing his treatises; this means "from Seville". The other source gives us not only the information that he came from Seville, but also a good estimate for the period in which he lived. The information comes from Maimonides. Moses Maimonides, whose Arabic name was Abu 'Imran Musa ibn Maymun ibn 'Ubayd Allah, was a Jewish philosopher, jurist, and physician who was born in Córdoba in 1135. Among many important works he wrote The Guide of the Perplexed in Arabic in which he writes of:- ... ibn Aflah of Seville, whose son I have met ...

Extractions: Additional illustrations courtesy of Bodleian Library Towards the end of the 10th century, Ibn al-Nadim, son of a Baghdad , bookseller and boon companion of Abbasid caliphs, compiled an annotated bibliography of books that had passed through his hands during the course of his long and active life. The sheer number of books that he lists, to say nothing of the range of their subject matter, is astonishing: Aristotle appears beside Sindbad the Sailor, Euclid beside the stories of Goha, Plato beside the poems of'Antar ibn Shad-dad. The most striking feature of Ibn al-Nadim's catalog, however, is the number of books dealing with science. In a chapter entitled The Reason Why Books on Philosophy and Other Ancient Sciences Became Plentiful in This Country, Ibn al-Nadim relates a strange story of how Aristotle appeared in a dream to the Caliph al-Ma'mun and assured him that there was no conflict between reason and revelation. Thus reassured, al-Ma'mun set about obtaining the works of the Greek philosophers, the first step toward founding the famous House of Wisdom, a center for the translation of Greek scientific works into Arabic. Ibn al-Nadim told the story this way: This dream was one of the most definite reasons for the output of books. Between al-Ma'mun and the Byzantine emperor there was correspondence ... so al-Ma'mun wrote to the Byzantine emperor asking his permission to obtain a selection of old scientific manuscripts, stored and treasured in the country of the Byzantines. After first refusing, he finally complied, and al-Ma'mun sent forth a number of scholars, among them al-Hajjaj ibn Matar, Ibn al-Batrik, Salman, the director of the House of Wisdom and many others. They selected books from those they found and brought them back to al-Ma'mun, who ordered them to prepare translations of them.
Extractions: (10 to 11th century A.D.) T he turn of the first millennium was a time of intense research in mathematics, physics, and astronomy. One scientist active and productive in all of these fields was Ibn al-Haytham, called by his successors of the 12th century "Ptolemy the Second." Ibn al-Haytham, also known as Alhazen (the Latin transliteration of his first name al-Hasan), was born in Iraq, most likely in Bassorah, in the second half of the 10th century. He arrived in Cairo under the reign of Fatimid Caliph al-Hakim, a patron of the sciences who was particularly interested in astronomy. Ibn al-Haytham proposed to the Caliph a hydraulic project to control the flow of the Nilean early Aswan dam. The Caliph refused, but al-Haytham continued to live in Cairo, in the neighborhood of the famous University of al-Azhar, until his death after 1040.

Extractions: Thabit and his pupils lived in this midst. He worked in Baghdad and he occupied himself with mathematics astronomy mechanics medicine and philosophy. His native language was Syriac which was the eastern Aramaic dialect from Edessa and he knew well also Greek. He translated from Greek Apollonius Archimedes Euclid and Ptolemy. Thabit had revised translation of Euclid Elements of Hunayn ibn Ishaq. He had also rewritten the Hunayn's translation of Ptolemy's Almagest and he translated Ptolemy's Geography which later became very known. Later Thabit's patron was the Abbasid Caliph al-Mu'tadid (reigned 892902) and Thabit very soon became his personal friend and the visitor of his court. There are just a few original Thabit's works that were preserved. Thabit has developed a theory about the trepidation and oscilation of the equinoctial points of which many scolars debated in the Middle Ages. According to Copernicus Thabit has determined the length of the sidereal year 365d 6h 9m 12s (an error of 2s). He published his observations of the Sun. In mathematics Thabit discovered an equation for determining the amicable numbers.

Extractions: Arab Contributions Within a century of Muhammad's conquest of Mecca, Islamic armies conquered lands from northern Africa, southern Europe, through the Middle East and east up to India. Within a century of that the Caliphate split up into several parts. The eastern segment, under the Abbasid caliphs, became a center of growth, of luxury, and of peace. In 766 the caliph al-Mansur founded his capitol in Baghdad and the caliph Harun al-Rashid, established a library. The stage was set for his successor, Al-Ma'mum. In the 9 century Al-Ma'mum established Baghdad as the new center of wisdom and learning. He establihed a research institute, the Bayt al-Hikma (House of Wisdom), which would last more than 200 years. Al-Ma'mum was responsible for a large scale translation project of as many ancient works as could be found. Greek manuscripts were obtained through treaties. By the end of the century, the major works of the Greeks had been translated. In addition, they learned the mathematics of the Babylonnians and the Hindus. What follows is a brief introduction to a few of the more prominent Arab mathematicians, and a sample of their work

Extractions: Back to Math Words Alphabetical Index Aliquot parts of a number are proper divisors of the number that are smaller than the number. The aliquot parts of six are one, two, and three. The word joins two unlikely partners, the Latin ali for "other" and quot for how many. Together they came to mean a part of something, in this case, a part of the number of which it is a factor. The "other" meaning of ali remains today in words like alius, alibi, and alien. The quot root remains in quotient. Aliquot chains, sometimes called sociable chains , are formed by taking the sum of the aliquot parts and adding them to form a new number, then repeating this process on the next number. For some numbers, the result will bring you directly back to the original number. In that case the two numbers are called amicable numbers . For example, 220 and 284 are amicable numbers. The divisors of 220 are 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110 and if you add all these numbers together, you can see they sum to 284. The aliquot parts of 284 are 1, 2, 4, 71, 142 and these sum to 220. The relationship between 220 and 284 was known at least as far back as Pythagorus (500 BC). Sam Kutler has written to tell me that the first use of a term like "friend" for the pair was in a commentary on the work of Nicomachus by Iamblichus, around 300 AD. He also thought the Greek term was
Extractions: 15. THE CITY OF SIN. We are now going to present the historical narrative, as complete as we can make it, in reverse order, from the school established by Agrippa in London, to the farthest back we can go. If we miss some group or another, we hope to make it up to you in the future. What we are about to detail in this narrative, pertains not only to the Sabians of Harran, but to the entire Western Esoteric Tradition, aka the Hermetic Tradition. This is a telling of the antiquities of the Hermetic Tradition, at least as far as how it was transmitted, from the East, to Florence, and the rest of Europe. New materials for 11 March 2002: new remarks from Ambelain more on the Boghdadiens According to Robert Ambelain, in Le Martinisme , some new information is coming to light as to the origins of the R+C which are not very far off from what we have been piecing together from the materials made available to us. It is not entirely possible for us at least, to find the proofs which Ambelain asserts regarding Agrippa, but here we go with a quote: "Dès le debut du XVI° siècle, nous voyons fonctionner l'association secrète de la "Communauté des Mages", fondée par Henri Cornélius Agrippa, association qui groupait les maîtres contemporains de l'Achimie et de la Magie.

Extractions: Books on Syriac Studies You are here: Beth Mardutho About The Syriac Language Part of World Civilization Navigate: Origins of Syriac Early Literature Golden Age Part of World Civilization ... Today World civilization passes from one region to another, and from one language to another, by contact. If we are to trace the history of any field of science, we begin with the ancient Mesopotamians and Egyptians, moving to the Greeks and Romans, then to the Arabs, ending up in Western Europe (not to underestimate the civilizations of Asia and South America). One stop in this journey is almost always forgotten: the Syriac contribution! From the 4th century onward, the Greek sciences were translated into Syriac, including philosophy, logic, medicine, mathematics, astronomy and alchemy. When the Arabs desired to transmit the Greek sciences into Arabic during the 8th and 9th centuries, they turned to their Syriac subjects to do the task. In most cases, these Syriac scholars translated the works first into their native language then into Arabic. As a result, many of the Arabic scientific terminology, including the names of plants, are rooted in Syriac. Scientific works and terminology from other cultures, such as Persian and Indian, passed to Arabic via Syriac; a noted example is the name of the chemical element Zirconium (via Syriac
