Question: Who covered the most disciplines, Abū Sahl al-Qūhī or Al-Farabi?
Context: Ibn al-Ajdābī (Arabic: أبو إسحاق إبراهيم بن إسماعيل بن أحمد بن عبد الله اللواتي الأجدابي الطرابلسي‎ ‎ , Abū Ishāq Ibrāhīm ibn Ismā'īl ibn Ahmad ibn Abdallāh al-Lawātī al-Ajdābī al-Tarāblisī) died after c. 1077 AD (456 AH) was a prominent Libyan scholar and linguist.  His fields of expertise covered Islamic jurisprudence, kalam, Arabic language and astronomy.  He lived all his life in Tripoli and died and was buried there.  He studied under Libyan scholars of his time and was famous for being interested in meeting those who traveled through Tripoli from the Mashriq and the Maghrib and acquiring wider knowledge from them.  It is said that when he was asked about how he acquired all this knowledge, he replied, "I acquired it from the Huwwāra and Znāta gates," which refers to the names of two main gates to Tripoli, named after two Berber tribes. Aboureihan Educational Complex (Persian: مجتمع آموزشی ابوریحان) is a high school and middle school complex located in Qeitarie district, Saba Blvd. northern Tehran, Iran.  Founded in 1991, it is named after Abū Rayḥān Muḥammad-ebne Aḥmad Biruni (Persian: ابوریحان محمد بن احمد بیرونی), an 11th-century Persian scholar, philosopher, and polymath from the province Khwarazm (today Turkmenistan, Uzbekistan, and parts of Kazakhstan).  The school emphasizes experimental and mathematical disciplines throughout the high school education.  Aboureihan high school is considered one of the most prestigious schools for girls in Iran (as all of the schools are single-sex). The Macy Conferences were a set of meetings of scholars from various disciplines held in New York under the direction of Frank Fremont-Smith at the Josiah Macy, Jr.  Foundation starting in 1941 and ending in 1960.  The explicit aim of the conferences was to promote meaningful communication across scientific disciplines, and restore unity to science.  There were different sets of conferences designed to cover specific topics, for a total of 160 conferences over the 19 years this program was active; the phrase "Macy conference" does not apply only to those on cybernetics, although it is sometimes used that way informally by those familiar only with that set of events.  Disciplinary isolation within medicine was viewed as particularly problematic by the Macy Foundation, and given that their mandate was to aid medical research, they decided to do something about it.  Thus other topics covered in different sets of conferences included: aging, adrenal cortex, biological antioxidants, blood clotting, blood pressure, connective tissues, infancy and childhood, liver injury, metabolic interrelations, nerve impulse, problems of consciousness, and renal function. Al-Farabi ( ; Persian: ابو نصر محمد بن محمد فارابي‎ ‎ "Abū Naṣr Muḥammad ibn Muḥammad Al Fārābī ";, known in the West as Alpharabius (c. 872 in Fārāb – between 14 December, 950 and 12 January, 951 in Damascus), was a renowned philosopher and jurist who wrote in the fields of political philosophy, metaphysics, ethics and logic.  He was also a scientist, cosmologist, mathematician and music scholar. Abū Sahl Wayjan ibn Rustam al-Qūhī (al-Kūhī ; Persian: ابوسهل بیژن کوهی‎ ‎ "Abusahl Bijan-e Koohi") was a Persian mathematician, physicist and astronomer.  He was from Kuh (or Quh), an area in Tabaristan, Amol, and flourished in Baghdad in the 10th century.  He is considered one of the greatest Muslim geometers, with many mathematical and astronomical writings ascribed to him. Abū Ṭalḥa, Zayd ibn Sahl ibn al-Aswad ibn Ḥarām al-Khazrajī, was a renowned Companion of the Prophet Muḥammad and one of the Anṣār (the ‘Helpers’) of Medina.  He was from Banu Khazraj, which after the Hijrah came to be known as the Ansar.  He was mostly known as a valiant fighter and skilful archer of the early Islamic period.  Abū Ṭalḥa was known to have been a horseman of the Prophet and was at the Prophet's side during the oath of allegiance at al-ʿAqaba and in the battles of Badr, Uḥud and Khandaq. Underwater orienteering is an underwater sport that uses recreational open circuit scuba diving equipment and consists of a set of individual and team events conducted in both sheltered and open water that test the competitors competency in underwater navigation.  The competition is principally concerned with the effectiveness of navigation technique used by competitors to swim an underwater course following a route marked on a map prepared by the competition organisers, a compass and a counter meter to measure the distance covered.  The sport was developed in the Soviet Union during the late 1950s and is currently played mainly in Europe.  It is known as "Orientation Sub" in French and as " La Orientación Subacuática" in Spanish.  Historically, the sport has also been known as "Technical Disciplines". Man Into Wolf; An Anthropological Interpretation of Sadism, Masochism and Lycanthropy is a book by Robert Eisler, published in 1948 .  The text is based upon his readings in archeology and anthropology; anything not covered by these disciplines is then dealt with using Jungian methods of dream analysis and the theory of archetypes.  For instance, his remarks concerning the nature of life in prehistory are largely derived from his interpretations of the dreams of psychotherapy patients. Dhūl-Nūn Abū l-Fayḍ Thawbān b. Ibrāhīm al-Miṣrī (Arabic: ذو النون المصري‎ ‎ ; d. Giza, in 245/859 or 248/862), often referred to as Dhūl-Nūn al-Miṣrī or Zūl-Nūn al-Miṣrī for short, was an early Egyptian Muslim mystic and ascetic of Nubian origin.  Born in Upper Egypt in 796, Dhul-Nun is said to have made some study of the scholastic disciplines of alchemy, medicine, and Greek philosophy in his early life, before coming under the mentorship of the mystic Saʿdūn of Cairo, who is described in traditional accounts of Dhul-Nun's life as both "his teacher and spiritual director."  Celebrated for his legendary wisdom both in his own life and by later Islamic thinkers, Dhul-Nun has been venerated in traditional Sunni Islam as one of the greatest saints of the early era of Sufism. Structural and Multidisciplinary Optimization is a peer-reviewed scientific journal published by Springer Science+Business Media.  It is the official journal of the International Society of Structural and Multidisciplinary Optimization.  It covers all aspects of designing optimal structures in stressed systems as well as multidisciplinary optimization techniques when one of the disciplines deals with structures (stressed solids) or fluids.  The journal's scope ranges from the mathematical foundations of the field to algorithm and software development with benchmark studies to practical applications and case studies in structural, aero-space, mechanical, civil, chemical, and naval engineering.  Closely related fields such as computer-aided design and manufacturing, reliability analysis, artificial intelligence, system identification and modeling, inverse processes, computer simulation, and active control of structures are covered when the topic is relevant to optimization.  The current editor-in-chief since 2015 is Raphael T. Haftka (University of Florida) since the passage of the founding editor George I. N. Rozvany (Budapest University of Technology and Economics).
