Al Achsasi Al Mouakket
Muḥammad al Achsasi al Mouakket () was a 17th century Egyptian astronomer whose and catalogue of stars, ("''Pearls of brilliance upon the solar operations''"), was written in Cairo in about 1650. Al-Achsasi was a shaykh, a learned elder, of the Grand Mosque of the university of Cairo, where his name reflected his position in regulating the times and hours at the mosque. connects him in origin to a village in the Faiyum, southwest of Cairo. No copies of al-Achsasi's book were known to Western astronomers or historians of science until 1895, when the incomplete manuscript was obtained by the amateur English astronomer Edward Ball Knobel; thus al-Achsasi did not appear in the standard French and English bibliographies and library catalogues of the 19th century. Knobel announced his discovery of the work in the journal of the Royal Astronomical Society The Royal Astronomical Society (RAS) is a learned society and charitable organisation, charity that encourages and promote ...

Astronomer
An astronomer is a scientist in the field of astronomy who focuses on a specific question or field outside the scope of Earth. Astronomers 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 typically 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 Con ...

Muwaqqit
In the history of Islam, a ''muwaqqit'' (, 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 whose holder dealt exclu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mosque
A mosque ( ), also called a masjid ( ), is a place of worship for Muslims. The term usually refers to a covered building, but can be any place where Salah, Islamic prayers are performed; such as an outdoor courtyard. Originally, mosques were simple places of prayer for the early Muslims, and may have been open spaces rather than elaborate buildings. In the first stage of Islamic architecture (650–750 CE), early mosques comprised open and closed covered spaces enclosed by walls, often with minarets, from which the Adhan, Islamic call to prayer was issued on a daily basis. It is typical of mosque buildings to have a special ornamental niche (a ''mihrab'') set into the wall in the direction of the city of Mecca (the ''qibla''), which Muslims must face during prayer, as well as a facility for ritual cleansing (''wudu''). The pulpit (''minbar''), from which public sermons (''khutbah'') are delivered on the event of Friday prayer, was, in earlier times, characteristic of the central ...

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. Protoscience, early sciences, and natural philosophies such as alchemy and astrology that existed during the Bronze Age, Iron Age, classical antiquity and the Middle Ages, declined during the early modern period after the establishment of formal disciplines of science in the Age of Enlightenment. The earliest roots of scientific thinking and practice can be traced to Ancient Egypt and Mesopotamia during the 3rd and 2nd millennia 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manuscript
A manuscript (abbreviated MS for singular and MSS for plural) was, traditionally, any document written by hand or typewritten, as opposed to mechanically printed or reproduced in some indirect or automated way. More recently, the term has come to be understood to further include ''any'' written, typed, or word-processed copy of an author's work, as distinguished from the rendition as a printed version of the same. Before the arrival of prints, all documents and books were manuscripts. Manuscripts are not defined by their contents, which may combine writing with mathematical calculations, maps, music notation, explanatory figures, or illustrations. Terminology The word "manuscript" derives from the (from , hand and from , to write), and is first recorded in English in 1597. An earlier term in English that shares the meaning of a handwritten document is "hand-writ" (or "handwrit"), which is first attested around 1175 and is now rarely used. The study of the writing ( ...

He started to study law but his love of geology made him change to the Government School of Mines (now part of Imperial College London) in 1861. In 1862, he changed his career again, starting to work for Bass & Co. at Burton upon Trent as an analytical chemist in the brewery department. He rose to become a manager and Head Brewer. He then became a manager of a Courtauld's silk factory at Bocking in 1875. His final position was with the Ilford Photographic Company. In 1872, he purchased an 8.5 inch reflecting telescope to further his interest in astronomy. His work on a publication about the chronology of star catalogues in 1875 let him to study the work of early Arab astronomers and learn some Arabic and Persian. He then prepared a new edition of the star catalogue in the Almagest using all available sources in Greek, Arabic and Lati ...
