Al Achsasi Al Mouakket
Muḥammad al-Akhṣāṣī al-Muwaqqit ( ar, محمد الاخصاصي الموقت) was an Egyptian astronomer whose and catalogue of stars, ('Pearls of brilliance upon the solar operations'), was written at Cairo about 1650. Al-Akhsasi was a shaykh, a learned elder, of the Grand Mosque of the university of Cairo, where his name ''al- Muwaqqit'' reflected his position regulating the times and hours at the mosque. His name Akhsasi connects him in origin to a village in the Faiyum, southwest of Cairo. No copies of his book were known to Western astronomers or historians of science The history of science covers the development of science from ancient times to the present.

Astronomer
An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth. They observe astronomical objects such as stars, planets, natural satellite, moons, comets and galaxy, galaxies – in either observational astronomy, observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, Sun, solar astronomy, the Star formation, origin or stellar evolution, evolution of stars, or the galaxy formation and evolution, formation of galaxies. A related but distinct subject is physical cosmology, which studies the Universe as a whole. Types Astronomers usually fall under either of two main types: observational astronomy, observational and theoretical astronomy, theoretical. Observational astronomers make direct observations of Astronomical object, celestial objects and analyze the data. In contrast, theoretical astronomers create and investigate C ...

Cairo
Cairo ( ; ar, القاهرة, al-Qāhirah, ) is the capital of Egypt and its largest city, home to 10 million people. It is also part of the largest urban agglomeration in Africa, the Arab world and the Middle East: The Greater Cairo metropolitan area, with a population of 21.9 million, is the 12th-largest in the world by population. Cairo is associated with ancient Egypt, as the Giza pyramid complex and the ancient cities of Memphis and Heliopolis are located in its geographical area. Located near the Nile Delta, the city first developed as Fustat, a settlement founded after the Muslim conquest of Egypt in 640 next to an existing ancient Roman fortress, Babylon. Under the Fatimid dynasty a new city, ''al-Qāhirah'', was founded nearby in 969. It later superseded Fustat as the main urban centre during the Ayyubid and Mamluk periods (12th–16th centuries). Cairo has long been a centre of the region's political and cultural life, and is titled "the city of a thousand m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monthly Notices Of The Royal Astronomical Society
''Monthly Notices of the Royal Astronomical Society'' (MNRAS) is a peer-reviewed scientific journal covering research in astronomy and astrophysics. It has been in continuous existence since 1827 and publishes letters and papers reporting original research in relevant fields. Despite the name, the journal is no longer monthly, nor does it carry the notices of the Royal Astronomical Society. History The first issue of MNRAS was published on 9 February 1827 as ''Monthly Notices of the Astronomical Society of London'' and it has been in continuous publication ever since. It took its current name from the second volume, after the Astronomical Society of London became the Royal Astronomical Society (RAS). Until 1960 it carried the monthly notices of the RAS, at which time these were transferred to the newly established ''Quarterly Journal of the Royal Astronomical Society'' (1960–1996) and then to its successor journal ''Astronomy & Geophysics'' (since 1997). Until 1965, MNRAS ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Al-Azhar Mosque
Al-Azhar Mosque ( ar, الجامع الأزهر, al-Jāmiʿ al-ʾAzhar, lit=The Resplendent Congregational Mosque, arz, جامع الأزهر, Gāmiʿ el-ʾazhar), known in Egypt simply as al-Azhar, is a mosque in Cairo, Egypt in the historic Islamic core of the city. Commissioned by Jawhar al-Siqilli shortly after Cairo was established as the new capital of the Fatimid Caliphate in 970, it was the first mosque established in a city that eventually earned the nickname "the City of a Thousand Minarets". Its name is usually thought to derive from ''az-Zahrāʾ'' (meaning "the shining one"), a title given to Fatimah, the daughter of Muhammad. After its dedication in 972, and with the hiring by mosque authorities of 35 scholars in 989, the mosque slowly developed into what is today the second oldest continuously run university in the world after Al Karaouine in Idrisid Fes. Al-Azhar University has long been regarded as the foremost institution in the Islamic world for the study ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Muwaqqit
In the history of Islam, a ''muwaqqit'' ( ar, مُوَقَّت, more rarely ''mīqātī'') was an astronomer tasked with the timekeeping and the regulation of prayer times in an Islamic institution like a mosque or a madrasa. Unlike the muezzin (reciter of the call to prayer) who was usually selected for his piety and voice, a muwaqqit was selected for his knowledge and skill in astronomy. Not all mosques had a muwaqqit. The office was first recorded in the late 13th century in the Mosque of Amr ibn al-As in the Mamluk Sultanate of Cairo and then spread to various parts of the Muslim world. Even then, many major mosques only relied on muezzins to determine prayer times using traditional methods, such as observing shadow lengths and twilight phenomena. The lack of historical sources and research makes it difficult to ascertain the specific functions and roles of the muwaqqit. There is uncertainty among historians of science whether the muwaqqit was a specialised office whos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Faiyum ( ar, الفيوم ' , borrowed from cop, ̀Ⲫⲓⲟⲙ or Ⲫⲓⲱⲙ ' from egy, pꜣ ym "the Sea, Lake") is a city in Middle Egypt. Located southwest of Cairo, in the Faiyum Oasis, it is the capital of the modern Faiyum Governorate. Originally called Shedet in Egyptian, the Greeks called it in grc-koi, Κροκοδειλόπολις, Krokodilópolis, and later grc-byzantine, Ἀρσινόη, Arsinoë. It is one of Egypt's oldest cities due to its strategic location. Name and etymology Originally founded by the ancient Egyptians as Shedet, its current name in English is also spelled as Fayum, Faiyum or Al Faiyūm. Faiyum was also previously officially named Madīnet Al Faiyūm (Arabic for ''The City of Faiyum''). The name Faiyum (and its spelling variations) may also refer to the Faiyum Oasis, although it is commonly used by Egyptians today to refer to the city. The modern name of the city comes from Coptic / ' (whence the proper name '), meaning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Historians Of Science
The history of science covers the development of science from ancient times to the present. It encompasses all three major branches of science: natural, social, and formal. Science's earliest roots can be traced to Ancient Egypt and Mesopotamia around 3000 to 1200 BCE. These civilizations' contributions to mathematics, astronomy, and medicine influenced later Greek natural philosophy of classical antiquity, wherein formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Latin-speaking Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but continued to thrive in the Greek-speaking Eastern Roman (or Byzantine) Empire. Aided by translations of Greek texts, the Hellenistic worldview was preserved and absorbed into the Arabic-speaking Muslim world during the Islamic Golden Age. The recovery and as ...
