Burning Glass
A burning glass or burning lens is a large convex lens that can concentrate the Sun's rays onto a small area, heating up the area and thus resulting in ignition of the exposed surface. Burning mirrors achieve a similar effect by using reflecting surfaces to focus the light. They were used in 18th-century chemical studies for burning materials in closed glass vessels where the products of combustion could be trapped for analysis. The burning glass was a useful contrivance in the days before electrical ignition was easily achieved. History Burning glass technology has been known since antiquity, as described by Greek and Roman writers who recorded the use of lenses to start fires for various purposes. Pliny the Elder noted the use of glass vases filled with water to concentrate sunlight heat intensely enough to ignite clothing, as well as convex lenses that were used to cauterize wounds. Plutarch refers to a burning mirror made of joined triangular metal mirrors installed at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gaspar Schott
Gaspar Schott (German language, German: ''Kaspar'' (or ''Caspar'') ''Schott''; Latin: ''Gaspar Schottus''; 5 February 1608 – 22 May 1666) was a Germans, German Jesuit and scientist, specializing in the fields of physics, mathematics and natural philosophy, and known for his industry. Biography He was born at Bad Königshofen im Grabfeld. It is probable, but not certain, that his early education was at the Jesuit College at Würzburg. In any case, at the age of 19 he joined the Society of Jesus, entering the novitiate at Trier on 30 October 1627. After two years of novitiate training, he matriculated at the University of Würzburg on 6 November 1629 to begin a three-year study of Philosophy, following the normal academic path prescribed for Jesuit seminarians. Owing to the Swedish invasion of Würzburg in October 1631, the Jesuit community fled the city. Schott went, first to the Jesuit seminary of Tournai in Belgium, and subsequently, in 1633, to Caltagirone in Sicily, where he ...

Athanasius Kircher
Athanasius Kircher (2 May 1602 – 27 November 1680) was a German Society of Jesus, Jesuit scholar and polymath who published around 40 major works of comparative religion, geology, and medicine. Kircher has been compared to fellow Jesuit Roger Joseph Boscovich and to Leonardo da Vinci for his vast range of interests, and has been honoured with the title "Master of a Hundred Arts".Woods, p. 108. He taught for more than 40 years at the Roman College, where he set up a wunderkammer or cabinet of curiosities that would become the Kircherian Museum. A resurgence of interest in Kircher has occurred within the scholarly community in recent decades. Kircher claimed to have deciphered the Egyptian hieroglyphs, hieroglyphic writing of the ancient Egyptian language, but most of his assumptions and translations in the field turned out to be wrong. He did, however, correctly establish the link between the ancient Egyptian and the Coptic language, Coptic languages, and some com ...

Roger Bacon
Roger Bacon (; or ', also '' Rogerus''; ), also known by the Scholastic accolades, scholastic accolade ''Doctor Mirabilis'', was a medieval English polymath, philosopher, scientist, theologian and Franciscans, Franciscan friar who placed considerable emphasis on the study of nature through empiricism. Intertwining his Catholic faith with scientific thinking, Roger Bacon is considered one of the greatest polymaths of the Medieval Period, medieval period. In the Early modern period, early modern era, he was regarded as a Wizard (paranormal), wizard and particularly famed for the story of his History of robots, mechanical or necromancy, necromantic brazen head. He is credited as one of the earliest European advocates of the modern scientific method, along with his teacher Robert Grosseteste. Bacon applied the empirical method of Ibn al-Haytham (Alhazen) to observations in texts attributed to Aristotle. Bacon discovered the importance of empirical testing when the results he obt ...

Book Of Optics
The ''Book of Optics'' (; or ''Perspectiva''; ) is a seven-volume treatise on optics and other fields of study composed by the medieval Arab scholar Ibn al-Haytham, known in the West as Alhazen or Alhacen (965–c. 1040 AD). The ''Book of Optics'' presented experimentally founded arguments against the widely held extramission theory of vision (as held by Euclid in his ''Optica''), and proposed the modern intromission theory, the now accepted model that vision takes place by light entering the eye.D. C. Lindberg (1976), ''Theories of Vision from al-Kindi to Kepler'', Chicago, Univ. of Chicago Press The book is also noted for its early use of the scientific method, its description of the camera obscura, and its formulation of Alhazen's problem. The book extensively affected the development of optics, physics and mathematics in Europe between the 13th and 17th centuries. Vision theory Before the ''Book of Optics'' was written, two theories of vision existed. The extra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ibn Sahl (mathematician)
Ibn Sahl (full name: ''Abū Saʿd al-ʿAlāʾ ibn Sahl'' ; c. 940–1000) was a Persian people, Persian mathematician and Islamic physics, physicist of the Islamic Golden Age, associated with the Buyid dynasty, Buyid court of Baghdad. Nothing in his name allows us to glimpse his country of origin. He is known to have written an optical treatise around 984. The text of this treatise was reconstructed by Roshdi Rashed from two manuscripts (edited 1993).: Damascus, al-Ẓāhirīya MS 4871, 3 fols., and Tehran, Millī MS 867, 51 fols. The Tehran manuscript is much longer, but it is badly damaged, and the Damascus manuscript contains a section missing entirely from the Tehran manuscript. The Damascus manuscript has the title ''Fī al-'āla al-muḥriqa'' "On the burning instruments", the Tehran manuscript has a title added in a later hand ''Kitāb al-harrāqāt'' "The book of burners". Ibn Sahl is the first Muslim scholar known to have studied Ptolemy's ''Optics'', and as such an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Constantinople
Constantinople (#Names of Constantinople, see other names) was a historical city located on the Bosporus that served as the capital of the Roman Empire, Roman, Byzantine Empire, Byzantine, Latin Empire, Latin, and Ottoman Empire, Ottoman empires between its consecration in 330 until 1930, when it was renamed to Istanbul. Initially as New Rome, Constantinople was founded in 324 during the reign of Constantine the Great on the site of the existing settlement of Byzantium, and shortly thereafter in 330 became the capital of the Roman Empire. Following the collapse of the Western Roman Empire in the late 5th century, Constantinople remained the capital of the Eastern Roman Empire (also known as the Byzantine Empire; 330–1204 and 1261–1453), the Latin Empire (1204–1261), and the Ottoman Empire (1453–1922). Following the Turkish War of Independence, the Turkish capital then moved to Ankara. Although the city had been known as Istanbul since 1453, it was officially renamed as Is ...

Vitalian (general)
Vitalian (, ; died 520) was a general of the Eastern Roman Empire. A native of Moesia in the northern Balkans, and probably of mixed Roman and Gothic or Scythian barbarian descent, he followed his father into the imperial army, and by 513 had become a senior commander in Thrace. In that year he rebelled against Emperor Anastasius I (r. 491–518), whose fiscal stringency and promotion of Miaphysitism were widely unpopular, and allowed Vitalian to quickly win over large parts of the army and the people of Thrace to his cause. After scoring a series of victories over loyalist armies, Vitalian came to threaten Constantinople itself, and forced Anastasius to officially recant his adoption of Miaphysitism in summer 515. Soon after, however, as Anastasius failed to honour some of the terms of the agreement, Vitalian marched on Constantinople, only to be decisively defeated by Anastasius' admiral, Marinus. Vitalian fled to his native Thrace and remained in hiding until Anastasius's d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
