Extractions: Dennis the Small, a 6th century expert on canon law, has had an enduring, if unsung, influence on the affairs of the modern world. It was thanks to his calculations that the 2000th anniversary of Christ's birth was recently celebrated. Dionysus Exiguus, as he was then known, was charged in 525 by Pope John I with setting dates in the Christian calendar. Though he was a good mathematician, the accuracy of Dennis' calculations was limited by the information available at the time. Determining the date of Christ's crucifixionand therefore the date of Easterpresented an especially difficult challenge. Theologians had decreed that Easter should be marked on the Sunday after the first full moon after the vernal equinox, but without accurate solar and lunar calendars how could the church fathers predict the dates in the future? In The Sun in the Church (Harvard University Press, 366 pages) Professor J.L. Heilbron describes one inspired solution to working out the dates: metal lines inscribed in the floor of a large dark building with a hole in the roof to allow the noon sun to shine onto it.

No nama¾ovanie obrazu si vyadovalo nieko¾ko dní, ba aj mesiacov a jeho vernos závisela od zruènosti maliara. Èlovek teda rozmý¾al nad tým, ako by sa dal proces zobrazovania zrýchli, alebo aspoò zjednodui. Vymyslel rôzne zlepováky a e to skonèilo úspene, sa dozviete v prvej èasti mojej seminárnej práce Technický vývoj fotografie . Fotografia bola teda na svete. V tom období by sme ju mohli prirovna ku gymnazistovi po maturite. Potenciál schopností má, ale ete nevie, ako ich vyui. Fotografia mala schopnos verne zachyti obraz skutoènosti, ale nevedela akým spôsobom ju má uplatni.

Dávny objavitelia sa trápili s problémami a vàtalo im hlavou, ako zachyti obraz v èo najvyej kvalite a to i bez maliarskeho nadania. Predchodcom moderného fotografického prístroja bola camera obscura (lat. tmavá komora). Ide o skrinku s malým otvorom v jednej stene. Cez tento otvor vnikali slneèné lúèe a vytvárali obraz na matnici. Tento jav pozoroval u grécky filozof ARISTOTELES (384 322 p. n. l.). Vimol si, e slnko vrhalo otvormi v sieti na zemi svoj obraz. Tento jav tak isto pozoroval v 11. storoèí arabský matematik a prírodovedec ALI ABU ALHAZEN. Vyuil cameru obscuru pri pozorovaní èiastoèného zatmenia slnka.

Extractions: ORIGENS DO PROCESSO FOTOGRÁFICO 3. QUANTO MENOR O ORIFÍCIO MELHOR A NITIDEZ DA IMAGEM MAS... Alguns, na tentativa de melhorar a qualidade da imagem, diminuíam o tamanho do orifício, mas a imagem escurecia proporcionalmente, tornando-se quase impossível ao artista identificá-la. Este problema foi resolvido em 1550 pelo físico milanês Girolano Cardano, que sugeriu o uso da lente biconvexa junto ao orifício, permitindo desse modo aumentá-lo, para se obter uma imagem clara sem perder sua nitidez. Isto foi possível, graças à capacidade de refração do vidro, que torna convergentes os raios luminosos refletidos pelo objeto; assim, alente fazia com que para cada ponto luminoso do objeto correspondesse a um ponto na imagem, formando-se ponto por ponto da luz refletida do objeto uma imagem puntiforme.

Calendar Reform by a congregation including the Jesuit mathematician Christoph Clavius and the Dominicanmathematician and instrumentmaker egnatio danti, the Gregorian reform http://www.hps.cam.ac.uk/starry/calendar.html
Extractions: Very large image (875K). A calendar is an instrument of society. Frequently offering guidance on weather and agricultural regimes, a calendar determines or influences the timing of religious festivals, civil and personal celebrations, the term of loans and contracts - anything, in fact, which is repeated cyclically or is set to occur or expire at some particular moment in the future. Apart from the day, a fundamental unit of human existence, a calendar may be constructed with regard to almost any combination of natural and artificial periods: weeks, lunar months, calendar months, solar and sidereal years, etc. Much astronomical work has been motivated by the need to maintain an existing calendar or establish the basis of a new one. In particular, astronomers have served calendrics through observations of the occurrences of particular phenomena (equinoxes, solstices, new moons, heliacal star risings) and the determination of the astronomical units of time and the relationship between them.

Extractions: Estúdio Ortensi - Artigo: História da Fotografia - A lente (texto de Mauricio Luiz Ortensi). São Paulo, 31 de maio de 2004. Boa tarde ! Introdução A Câmera escura A lente A fixação da imagem A cor O passado e o futuro A câmera escura representou um grande avanço no sentido de capturar imagens, mas apresenta um problema para que a imagem projetada seja nítida, o orifício da câmera precisa ser bem pequeno, para poder orientar os raios de luz que passam por ele - quanto menor o orifício, maior a nitidez. Mas, um orifício pequeno deixa passar pouca luz, tornando a imagem fraca - quanto menor o orifício, menor o brilho (figura 1). Se aumentarmos orifício, mais raios de luz passarão e deixarão a imagem mais forte, porém, estes raios não estarão tão ordenados, formando uma imagem desfocada (figura 2). A lente resolveu o problema do brilho e da nitidez da imagem, mas logo verificou-se que o foco obtido era limitado a um plano estreito, ou seja, apenas os objetos localizados a uma certa distância da lente ficavam nítidos; os que ficavam mais distantes ou mais próximos permaneciam desfocados.

En el siglo siguiente, en 1636, Daniel Schwenter describe un elaborado sistema de lentes que combina tres distancias focales diferentes en un mismo aparato, la "bola escióptrica", antecedente de la moderna lente zoom. Todos estos sistemas que permitían reproducir la "realidad", fueron utilizados profusamente, como veremos, para la realización de la obra de arte.
Extractions: 15TH CENTURY During the 15th century, Gainsborough painted many landscapes (perhaps for Alberti) on glass and made similar apparatti (show boxes) to that of Alberti. These boxes were wooden and had peep-holes at one side. The opposite end was open and had the glass-painted slide inserted and lit from behind by candles. A Gainsborough showbox is at the Victoria and Albert Museum , London. c. 1420 JOHANNES DE FONTANA ( - ) What appears to be the earliest-ever illustration of the camera obscura is found in a book by Fontana in 1420. The drawing shows a nun holding a vertically-shaped camera with an image on the inside. Historians and commentators routinely speak of this illustration as a lantern, however the appratus held is nothing like a lantern. The camera obscura contains the image and the lantern projects it. In this drawing by Fontana we see the image within the held object. The subject image is in no way being "projected". One aspect of the supposed image (devilish character) is interesting however; the lantern very early became an instrument to instil fear in it's viewers. Diabolic and demonic themes were common. In France for instance, the lantern became known as the Lanterne de Peur or "Lantern of Fear" . To date, all other interests have only described the camera with reference to it's appearance but with no actual drawing or illustration. Could this drawing of Fontana's be the same as referenced by Siegfried Zielinski in his piece on Cinema Archaeology when he states regarding the magic lantern.......

Extractions: I 1500-tallet var den gamle "Julianske Kalender" Pave Gregor XIII (1572-1585) , der endelig i 1582 tog det store skridt og nedsatte en kommission til udarbejdelse af en ny kalender , som kaldes "den gregorianske" efter ham. Kommissionen lededes af astronomen og domenikanermunken Egnatio Danti og det blev et forslag af Luigi Lilio fra Calabria, som man enedes om at sætte i værk. Trods det generelle problem med den gamle kalenders Santa Maria degli Angeli Kejser Constantin's Den Gregorianske Kalender bruges stadig, den er dog heller ikke helt nøjagtig, idet et "Gregoriansk år" er næsten 26 sekunder længere end "solåret" og tiden derfor allerede er næsten 3 timer foran den "rigtige" soltid. I løbet af 3.571 år skulle denne unøjagtighed løbe op til en hel dag, så en gang i fremtiden skal vor kalender atter justeres.

BROAD any people know that the Roman Catholic Church once waged a long and bitter war on science, and on astronomy in particular. But that seemingly well-established fact of history, it turns out, is wrong. Harvard University Press Science and religion blend as sunbeams enter the Shrine of Remembrance in Melbourne, Australia. While it is true that the church condemned Galileo, new research shows that centuries of oversimplifications have concealed just how hard Rome worked to amass astronomical tools, measurements, tests and lore. In its scientific zeal, the church adapted cathedrals across Europe, and a tower at the Vatican itself, so their darkened vaults could serve as solar observatories. Beams of sunlight that fell past religious art and marble columns not only inspired the faithful but provided astronomers with information about the Sun, the Earth and their celestial relationship. Among other things, solar images projected on cathedral floors disclosed the passage of dark spots across the Sun's face, a blemish in the heavens, which theologians once thought to be without flaw.
Anamorfosi - Trattatistica 1600 di allungamento dell immagine già esposto da egnatio danti nel trattato http://www.artetoma.it/anamorfosi/1600.html
Extractions: LA TRATTATISTICA DEL '600 Il XVII secolo si apre con la pubblicazione di un trattato di grande valore scientifico, il "Perspectivae Libri Sex" di Guidubaldo del Monte, per merito del quale la prospettiva si scuote decisamente di dosso tutte le incertezze e le inesattezze che in misura più o meno evidente avevano pesato sulla trattatistica precedente, assumendo finalmente i connotati scientifici che fin dal primo momento si era inteso darle. Per tutto il Seicento la prospettiva, e accanto ad essa l'anamorfosi, saranno oggetto di sempre più numerose trattazioni, quasi sempre per mano di matematici e geometri ormai impadronitisi della materia in maniera pressocché definitiva. GUIDUBALDO DEL MONTE PERSPECTIVAE LIBRI SEX pubblicato a Pesaro nel 1600 Siamo di fronte ad una trattazione rigorosamente scientifica: dalla definizione del punto di fuga, chiamato punctum concursus , alla rappresentazione su superfici inclinate, alla ricerca delle ombre e perfino alla risoluzione delle esigenze prospettiche legate alla scenografia teatrale. In particolare per noi riveste un grosso interesse il terzo libro in cui l'autore si impegna nella definizione dell'immagine prospettica su sezioni generiche, spingendosi nel campo delle anamorfosi coniche e piramidali che nel '600 imperverseranno nei vari cabinets francesi e nelle wunderkammern tedesche SALOMON DE CAUS LA PERSPECTIVE AVEC LA RAISON DES OMBRES ET MIROIRS
