Hypsicles
Hypsicles (; c. 190 – c. 120 BCE) was an ancient Greek mathematician and astronomer known for authoring ''On Ascensions'' (Ἀναφορικός) and possibly the Book XIV of Euclid's ''Elements''. Hypsicles lived in Alexandria. Life and work Although little is known about the life of Hypsicles, it is believed that he authored the astronomical work ''On Ascensions''. The mathematician Diophantus of Alexandria noted on a definition of polygonal numbers, due to Hypsicles: On Ascensions In ''On Ascensions'' (Ἀναφορικός and sometimes translated ''On Rising Times''), Hypsicles proves a number of propositions on arithmetical progressions and uses the results to calculate approximate values for the times required for the signs of the zodiac to rise above the horizon. It is thought that this is the work from which the division of the circle into 360 parts may have been adopted since it divides the day into 360 parts, a division possibly suggested by Babylonian astronom ...

John Of Seville
John of Seville (Latin: ''Johannes Hispalensis'' or ''Johannes Hispaniensis'') (fl. 1133-53) was one of the main translators from Arabic into Castilian in partnership with Dominicus Gundissalinus during the early days of the Toledo School of Translators. John of Seville translated a litany of Arabic astrological works in addition to being credited with the production of several original works in Latin. Life and Context John of Seville was a baptized Jew, whose Jewish name (now unknown) has been corrupted into "Avendeut", "Avendehut", "Avendar" or "Aven Daud". This evolved into the middle name "David", so that, as a native of Toledo, he is frequently referred to as Johannes (David) Toletanus. However, Avendehut's translations typically translated Arabic text into Spanish vernacular. John of Seville was capable of translating Arabic directly into Latin, creating a distinction between himself and Avendehut. Some historians argue that in fact there were two different persons with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aristotle
Aristotle (; 384–322 BC) was an Ancient Greek philosophy, Ancient Greek philosopher and polymath.

Ibn Al-Nadim
Abū al-Faraj Muḥammad ibn Isḥāq an-Nadīm (), also Ibn Abī Yaʿqūb Isḥāq ibn Muḥammad ibn Isḥāq al-Warrāq, and commonly known by the '' nasab'' (patronymic) Ibn an-Nadīm (; died 17 September 995 or 998), was an important Muslim bibliographer and biographer of Baghdad who compiled the encyclopedia '' Kitāb al-Fihrist'' (''The Book Catalogue'').

Graeco-Arabic Translation Movement
The Graeco-Arabic translation movement was a large, well-funded, and sustained effort responsible for translating a significant volume of secular Greek texts into Arabic. The translation movement took place in Baghdad from the mid-eighth century to the late tenth century. While the movement translated from many languages into Arabic, including Pahlavi, Sanskrit, Syriac, and Greek, it is often referred to as the Graeco-Arabic translation movement because it was predominantly focused on translating the works of Hellenistic scholars and other secular Greek texts into Arabic. Pre-Abbasid developments Pre-Islamic developments The ninth king of the Sasanian Empire, Shapur II, established the Academy of Gondishapur, which was to be a medical center, a library, as well as a college where various subjects like anatomy, theology, medicine, and philosophy would be studied. Later, Khosrow I established an observatory that could offer studies in dentistry, architecture, agriculture an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spherical Astrolabe
An armillary sphere (variations are known as spherical astrolabe, armilla, or armil) is a model of objects in the sky (on the celestial sphere), consisting of a spherical framework of rings, centered on Earth or the Sun, that represent lines of celestial longitude and latitude and other astronomically important features, such as the ecliptic. As such, it differs from a celestial globe, which is a smooth sphere whose principal purpose is to map the constellations. It was invented separately, in ancient China possibly as early as the 4th century BC and ancient Greece during the 3rd century BC, with later uses in the Islamic world and Medieval Europe. With the Earth as center, an armillary sphere is known as '' Ptolemaic''. With the Sun as center, it is known as '' Copernican''. The flag of Portugal features an armillary sphere. The armillary sphere is also featured in Portuguese heraldry, associated with the Portuguese discoveries during the Age of Exploration. Manuel I of Portug ...

Treatise
A treatise is a Formality, formal and systematic written discourse on some subject concerned with investigating or exposing the main principles of the subject and its conclusions."mwod:treatise, Treatise." Merriam-Webster Online Dictionary. Accessed September 12, 2020. A ''monograph'' is a treatise on a specialized topic. Etymology The word "treatise" has its origins in the early 14th century, derived from the Anglo-French term ''tretiz'', which itself comes from the Old French ''traitis'', meaning "treatise" or "account." This Old French term is rooted in the verb ''traitier'', which means "to deal with" or "to set forth in speech or writing". The etymological lineage can be traced further back to the Latin word ''tractatus'', which is a form of the verb ''tractare'', meaning "to handle," "to manage," or "to deal with". The Latin roots suggest a connotation of engaging with or discussing a subject in depth, which aligns with the modern understanding of a treatise as a formal ...

Euclid
Euclid (; ; BC) was an ancient Greek mathematician active as a geometer and logician. Considered the "father of geometry", he is chiefly known for the '' Elements'' treatise, which established the foundations of geometry that largely dominated the field until the early 19th century. His system, now referred to as Euclidean geometry, involved innovations in combination with a synthesis of theories from earlier Greek mathematicians, including Eudoxus of Cnidus, Hippocrates of Chios, Thales and Theaetetus. With Archimedes and Apollonius of Perga, Euclid is generally considered among the greatest mathematicians of antiquity, and one of the most influential in the history of mathematics. Very little is known of Euclid's life, and most information comes from the scholars Proclus and Pappus of Alexandria many centuries later. Medieval Islamic mathematicians invented a fanciful biography, and medieval Byzantine and early Renaissance scholars mistook him for the earlier philo ...

John Philoponus
John Philoponus ( Greek: ; , ''Ioánnis o Philóponos''; c. 490 – c. 570), also known as John the Grammarian or John of Alexandria, was a Coptic Miaphysite philologist, Aristotelian commentator and Christian theologian from Alexandria, Byzantine Egypt, who authored a number of philosophical treatises and theological works. John Philoponus broke from the Aristotelian– Neoplatonic tradition, questioning methodology and eventually leading to empiricism in the natural sciences. He was one of the first to propose a "theory of impetus" similar to the modern concept of inertia over Aristotelian dynamics. He is also the historical founder of what is now called the Kalam cosmological argument. Later in life Philoponus turned to Christian apologetics, arguing against the eternity of the world in his '' De opificio mundi'', a theory which formed the basis of pagan attacks on the Christian doctrine of Creation. He also wrote on Christology and was posthumously condemned as a here ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hero Of Alexandria
Hero of Alexandria (; , , also known as Heron of Alexandria ; probably 1st or 2nd century AD) was a Greek mathematician and engineer who was active in Alexandria in Egypt during the Roman era. He has been described as the greatest experimentalist of antiquity and a representative of the Hellenistic scientific tradition. Hero published a well-recognized description of a steam-powered device called an '' aeolipile'', also known as "Hero's engine". Among his most famous inventions was a windwheel, constituting the earliest instance of wind harnessing on land. In his work ''Mechanics'', he described pantographs. Some of his ideas were derived from the works of Ctesibius. In mathematics, he wrote a commentary on Euclid's ''Elements'' and a work on applied geometry known as the ''Metrica''. He is mostly remembered for Heron's formula; a way to calculate the area of a triangle using only the lengths of its sides. Much of Hero's original writings and designs have been lost, bu ...
