Cosmography
The term cosmography has two distinct meanings: traditionally it has been the protoscience of mapping the general features of the cosmos, heaven and Earth; more recently, it has been used to describe the ongoing effort to determine the large-scale features of the observable universe. Traditional usage The 14th-century work '' 'Aja'ib al-makhluqat wa-ghara'ib al-mawjudat'' by Persian physician Zakariya al-Qazwini is considered to be an early work of cosmography. Traditional Hindu, Buddhist and Jain cosmography schematize a universe centered on Mount Meru surrounded by rivers, continents and seas. These cosmographies posit a universe being repeatedly created and destroyed over time cycles of immense lengths. In 1551, Martín Cortés de Albacar, from Zaragoza, Spain, published ''Breve compendio de la esfera y del arte de navegar''. Translated into English and reprinted several times, the work was of great influence in Britain for many years. He proposed spherical charts and menti ...

'Aja'ib Al-makhluqat Wa-ghara'ib Al-mawjudat
Aja'ib al-Makhluqat wa Ghara'ib al-Mawjudat'', ( ar, عجائب المخلوقات وغرائب الموجودات, meaning ''The Wonders of Creatures and the Marvels of Creation'') is an important work of cosmography by Zakariya al-Qazwini, who was born in Qazwin (Iran) in the year 600 AH/1203 AD. Background to the work Qazwini's ''Aja'ib al-Makhluqat'' is criticized for being less than original. Substantial parts of his work are derivative of Yaqut's ''Mu'jam al-Buldan''. Qazwini mentions fifty names as his sources, the most important of whom are old geographers and historians such as al-Istakhri, Ibn Fadlan, al-Mas‘udi, Ibn Hawqal, al-Biruni, Ibn al-Athir, al-Maqdisi, and al-Razi. Notwithstanding the fact that Qazwini's work is a compilation of known and unknown sources, it influenced later works of Islamic cosmology and Islamic geography through its style and language. Qazwini's cosmography is not pure science but it also was intended to entertain its readers by enrichin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Martín Cortés De Albacar
Martín Cortés de Albacar (1510–1582) was a Spanish cosmographer.p131 Antonio Barrera-Osorio ''Experiencing nature: the Spanish American empire and the early scientific revolution;'' University of Texas Press, 2006 In 1551 he published the standard navigational textbook ''Arte de navegar'' (also known as ''Breve compendio'') Cortés was born in Bujaraloz, province of Zaragoza, Aragon. From 1530, in Cádiz, he taught cosmography and the art of navigation to pilots. ''Art of Navigation'' Cortés' book, ''Breve compendio,''...''Arte de navegar'' was promoted by Steven Borough who had it translated into English by Richard Eden and published in 1561 entitled ''The Art of Navigation.'' As such it became the first English manual of navigationAndrew Hadfield, ‘Eden, Richard (c.1520–1576)’, ''Oxford Dictionary of National Biography'', Oxford University Press, Sept 2004 and the primary text for European navigation throughout the early 17thC, enjoyed by such as Martin Frobisher ...

Zakariya Al-Qazwini
Zakariyya' al-Qazwini ( , ar, أبو يحيى زكرياء بن محمد بن محمود القزويني), also known as Qazvini ( fa, قزوینی), born in Qazvin (Iran) and died 1283, was a Persian cosmographer and geographer of Arab ancestry. He belonged to a family of jurists originally descended from Anas bin Malik (a companion of the Islamic prophet Muhammad) which had been well established in Qazvin long before al-Qazwini was born. His most famous work is the (), a seminal work in cosmography. He is also the author of the geographical dictionary (lit. 'Monuments of the Lands and Historical Traditions about Their Peoples'). Career Born in Qazvin, Iran, al-Qazwini served as a legal expert and judge in several localities in Iran. He traveled around in Mesopotamia and the Levant, and finally entered the circle patronized by the Ilkhanid governor of Baghdad, Ata-Malik Juvayni (d. 1283 CE). It was to the latter that al-Qazwini dedicated his famous cosmography titled ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jainism
Jainism ( ), also known as Jain Dharma, is an Indian religions, Indian religion. Jainism traces its spiritual ideas and history through the succession of twenty-four tirthankaras (supreme preachers of ''Dharma''), with the first in the current time cycle being Rishabhadeva, whom the tradition holds to have lived millions of years ago, the twenty-third ''tirthankara'' Parshvanatha, whom historians date to the 9th century BCE, and the twenty-fourth ''tirthankara'' Mahāvīra, Mahavira, around 600 BCE. Jainism is considered to be an eternal ''dharma'' with the ''tirthankaras'' guiding every time cycle of the Jain cosmology, cosmology. The three main pillars of Jainism are ''Ahimsa in Jainism, ahiṃsā'' (non-violence), ''anekāntavāda'' (non-absolutism), and ''aparigraha'' (asceticism). Jain monks, after positioning themselves in the sublime state of soul consciousness, take five main vows: ''ahiṃsā'' (non-violence), ''satya'' (truth), ''Achourya, asteya'' (not stealing), ''b ...

Observable Universe
The observable universe is a ball-shaped region of the universe comprising all matter that can be observed from Earth or its space-based telescopes and exploratory probes at the present time, because the electromagnetic radiation from these objects has had time to reach the Solar System and Earth since the beginning of the cosmological expansion. There may be 2 trillion galaxies in the observable universe, although that number was reduced in 2021 to only several hundred billion based on data from '' New Horizons''. Assuming the universe is isotropic, the distance to the edge of the observable universe is roughly the same in every direction. That is, the observable universe is a spherical region centered on the observer and is unique for every unique observational position. The word ''observable'' in this sense does not refer to the capability of modern technology to detect light or other information from an object, or whether there is anything to be detected. It refers to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Protoscience
__NOTOC__ In the philosophy of science, there are several definitions of protoscience. Its simplest meaning (most closely reflecting its roots of ''proto-'' + ''science'') involves the earliest eras of the history of science, when the scientific method was still nascent. The term can also be applied to modern emerging fields of study. Prescientific protoscience The term ''prescientific'' means at root "relating to an era before science existed". For example, traditional medicine existed for thousands of years before medical science did, and thus many aspects of it can be described as prescientific. In a related sense, protoscientific topics (such as the alchemy of Newton's day) can be called prescientific, in which case the ''proto-'' and ''pre-'' labels can function more or less synonymously (the latter focusing more sharply on the idea that nothing but science is science). Compared to fringe science, which is considered highly speculative or even strongly refuted, some protoscien ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Utopia
A utopia ( ) typically describes an imaginary community or society that possesses highly desirable or nearly perfect qualities for its members. It was coined by Sir Thomas More for his 1516 book ''Utopia (book), Utopia'', describing a fictional island society in the New World. However, it may also denote an intentional community. In common parlance, the word or its adjectival form may be used synonymously with "impossible", "far-fetched" or "deluded". Hypothetical utopias focus on—amongst other things—equality, in such categories as economics, government and justice, with the method and structure of proposed implementation varying based on ideology. Lyman Tower Sargent argues that the nature of a utopia is inherently contradictory because societies are not homogeneous and have desires which conflict and therefore cannot simultaneously be satisfied. To quote: The opposite of a utopia is a dystopia or cacotopia. Utopian and dystopian fiction has become a popular literary catego ...

Álfheimr
In Norse cosmology, Álfheimr (Old Norse: , "Land of the Elves" or "Elfland"; anglicized as Alfheim), also called "Ljósálfheimr" ( , "home of the Light Elves"), is home of the Light Elves. Attestations Álfheim as an abode of the Elves is mentioned only twice in Old Norse texts. The eddic poem ''Grímnismál'' describes twelve divine dwellings beginning the stanza 5 with: Ýdalir call they the place where Ull A hall for himself hath set; And Álfheim the gods to Frey once gave As a tooth-gift in ancient times. A tooth-gift was a gift given to an infant on the cutting of the first tooth. In the 12th century eddic prose ''Gylfaginning'', Snorri Sturluson relates it in the stanza 17 as the first of a series of abodes in heaven: That which is called Álfheim is one, where dwell the peoples called '' ljósálfar'' ight Elves but the '' dökkálfar'' ark Elvesdwell down in the earth, and they are unlike in appearance, but by far more ...

Chivalry
Chivalry, or the chivalric code, is an informal and varying code of conduct developed in Europe between 1170 and 1220. It was associated with the medieval Christianity, Christian institution of knighthood; knights' and gentlemen's behaviours were governed by chivalrous social codes. The ideals of chivalry were popularized in medieval literature, particularly the literary cycles known as the Matter of France, relating to the legendary companions of Charlemagne and his men-at-arms, the paladins, and the Matter of Britain, informed by Geoffrey of Monmouth's ''Historia Regum Britanniae'', written in the 1130s, which popularized the legend of King Arthur and his knights of the Round Table. All of these were taken as historically accurate until the beginnings of modern scholarship in the 19th century. The code of chivalry that developed in medieval Europe had its roots in earlier centuries. It arose in the Carolingian Empire from the idealisation of the cavalryman—involving mili ...

Chronology
Chronology (from Latin ''chronologia'', from Ancient Greek , ''chrónos'', "time"; and , '' -logia'') is the science of arranging events in their order of occurrence in time. Consider, for example, the use of a timeline or sequence of events. It is also "the determination of the actual temporal sequence of past events".Memidex/WordNet, "chronology,memidex.com (accessed September 25, 2010). Chronology is a part of periodization. It is also a part of the discipline of history including earth history, the earth sciences, and study of the geologic time scale. Related fields Chronology is the science of locating historical events in time. It relies upon chronometry, which is also known as timekeeping, and historiography, which examines the writing of history and the use of historical methods. Radiocarbon dating estimates the age of formerly living things by measuring the proportion of carbon-14 isotope in their carbon content. Dendrochronology estimates the age of trees by corre ...

European Renaissance
The Renaissance ( , ) , from , with the same meanings. is a period in European history marking the transition from the Middle Ages to modernity and covering the 15th and 16th centuries, characterized by an effort to revive and surpass ideas and achievements of classical antiquity. It occurred after the Crisis of the Late Middle Ages and was associated with great social change. In addition to the standard periodization, proponents of a "long Renaissance" may put its beginning in the 14th century and its end in the 17th century. The traditional view focuses more on the early modern aspects of the Renaissance and argues that it was a break from the past, but many historians today focus more on its medieval aspects and argue that it was an extension of the Middle Ages. However, the beginnings of the period – the early Renaissance of the 15th century and the Italian Proto-Renaissance from around 1250 or 1300 – overlap considerably with the Late Middle Ages, conventionally dat ...
