Extractions: DE ONTDEKKING VAN DE FOTOGRAFIE EERSTE FOTOGRAFISCHE OPNAME- EN BEHANDELINGSTOESTELLEN DE CAMERA OBSCURA De fotografische camera is ontstaan uit de camera obscura (= donkere ruimte). Reeds eeuwen geleden ontdekte men dat licht, dat door een klein gaatje in een donkere ruimte valt, op de tegenovergestelde wand een, op zijn kop staand, beeld geeft van het tafereel buiten de ruimte. De kennis van het optische princiep van camera obscura beelden kunnen tot Aristoteles getraceerd worden en zijn gebruik als tekenhulpmiddel tot Giovanni Battista della Porta. Het gebruik van de camera als observatiemiddel van zoneclipsen zonder de ogen te beschadigen door directe observatie werd door een aantal schrijvers vermeld. De eerst gepubliceerde illustratie ervan vindt men in 1545 in De radio astronomico et geometrico liber van de Hollandse fysicus en wiskundige Reiner Gemma Frisius. Leonardo da Vinci kende eveneens het verschijnsel van de camera obscura en maakte daar, op de door hem gebruikelijke manier, aantekeningen en schetsen van. In 1558 beschreef de Italiaanse natuurkundige Giovanni Batista della Porta in zijn boek Maggiae naturalis voor het eerst de camera obscura als een hulpmiddel bij het tekenen. In de tweede aanvullende editie, die 31 jaar later verscheen, breidde Porta zijn praktisch gebruik uit tot de portretkunst, waarbij het onderwerp, in volle zon, voor de opening in een vensterluik geplaatst werd.

Extractions: This file last modified 4/15/03 In about 1637, a French mathematical genius named Pierre de Fermat wrote in the margin of his copy of Arithmetica by Pythagorus, that he could prove that there were no solutions to the simple variation on Pythagorus' Theorem, a z + b z = c z Of course it is unreasonable to put together a list of the 100 most important books of the century. On the other hand, it is a lot of fun for a scientific bibliophile like me to think and argue about what ought to be on such a list. I think that the Morrisons may have given a few of the good books a status of excellence they probably don't deserve, but I was also delighted to see that some of my favorites (Gamov's "One Two Three ... Infinity" and Monod's "Chance and Necessity") are included. On the other hand, I would have put in Eigen and Winkler's "The Laws of the Game" and Hofstadter's "Godel, Escher, and Bach". The book list is accompanied by an article "Forced to Choose" (p. 545), in which a number of notable authors (including Roald Hoffman, John McPhee, E. O. Wilson, Berndt Heinrich, Kurt Vonnegut, and Carl Djerassi) express their opinions.

Extractions: Ce séminaire se propose de poursuivre les réflexions engagées ces trois dernières années au centre Koyré sur la formation des savoirs à l'époque moderne, en se centrant sur l'émergence d'un domaine de savoir qui est celui des arts, distinct à la fois de celui des métiers et des sciences spéculatives, ce que sanctionne l'Encyclopédie, Dictionnaire raisonnée des sciences des arts et des métiers. . L'instauration de l'art comme domaine d'exercice d'un savoir obéissant à des caractéristiques propres porte alors un nom, la « réduction en art ». Réduire en art est rassembler des savoirsépars, fragmentaires, et aussi non-écrits, les mettre en ordre méthodique à l'aide des mathématiques, de la rhétorique et de la figuration, afin de faciliter les choix techniques, et diffuser par l'écrit et le dessin, l'art ainsi formalisé, pour le rendre accessible au plus grand nombre. Toute une littérature technique s'inscrit dans ce modèle et le fait évoluer. Des historiens de l'art, des sciences et des techniques interviendront au cours de trois journées d'étude pour interroger leurs différents domaines sur cette question de la réduction en art.

Extractions: Todas las especulaciones que condujeron a la elaboración de la perspectiva geométrica centralizada, -el ojo único de Brunelleschi, el "intesector" , el "velum" o la "ventana de vidrio" -, hubieron de tener un fundamento experimental definitivo en la denominada "cámara obscura" . Seguramente Leonardo da Vinci (1452-15l8) obtuvo una verificación muy satisfactoria de sus ideas sobre la perspectiva, gracias a su empleo. En una de sus anotaciones dice: "Las imágenes de múltiples y distintos cuerpos se reproducen en un agudo orificio a través del cual, y por medio de líneas que, cortándose, generan pirámides contrarias, se proyectan cabeza abajo sobre la primera pared obscura". El nombre de "cámara obscura" , (hoy cámara oscura ), deriva de " CAMERA OBSCURA " , términos con los que, originariamente, se designaban determinadas habitaciones donde, una vez conseguida la oscuridad, se practicaba un pequeño orificio en una o en varias de sus paredes, a través del cual era proyectada sobre el muro opuesto o sobre una pantalla situada ante él una imagen invertida de la vista exterior.

Amherst College News Releases: Another important contribution of The Tower of the Winds is the first translationof an unpublished treatise on the winds by egnatio danti, the 16thcentury http://www.amherst.edu/~pubaff/news/news_releases/03/courtright03.html
Extractions: AMHERST, Mass.- In a new book, The Papacy and the Art of Reform in Sixteenth-Century Rome: Gregory XIII''s Tower of the Winds in the Vatican ($85, 344 pp., Cambridge University Press, Cambridge, 2004), Nicola Courtright, professor of fine arts at Amherst College, explains the import of the "Tower of the Winds," a three-story Vatican apartment built and painted to celebrate Gregory's greatest achievement: calendar reform and creation of the Gregorian calendar in 1582. The tower, she writes, "proclaimed with assurance not only Gregory's political and religious authority over the capital," but also his "domination of nature, time, and past and present cultures." In response to the Protestant Reformation, Gregory, who led the Roman church from1572 until his death in 1585, rebuilt and restored many of Rome's streets, churches and public monuments-and remade the calendar. Courtright writes, "The [Gregorian] calendar's purpose has become obscured in our post-Enlightenment age, because it was not changed for the sake of scientific accuracy." The Tower of the Winds "made clear to contemporaries the inextricably intertwined relationship of Gregory's calendar reform to his mission to renew faith and lead the Christian world toward redemption."

Extractions: Non esiste una sola prospettiva. I metodi che gli uomini hanno elaborato per mettere in prospettiva sono diversi come le società che li hanno usati e li usano. La prospettiva artificiale ebbe origine nel Quattrocento, in contrapposizione alla prospettiva naturale (teoria della visione). Fra le varie definizioni depoca, particolarmente efficace quella di Leonardo: "Prospettiva non è altro che vedere un sito dietro un vetro piano e ben trasparente, sulla superficie del quale siano segnate tutte le cose che gli stanno dietro: le quali si possono condurre per piramidi al punto dellocchio, ed esse piramidi si tagliano su detto vetro". more geometrico

Extractions: Durer situa-se ainda na tradição dos `tratados práticos` medievais. Wolfflin cita Durer: "Todas as criaturas são definidas pela sua proporção, pelo seu peso e pelas suas medidas". Wolfflin acrescenta: "Saber medir as coisas é saber compreendê-las". Durer situa-se num tempo intermédio, entre uma prática empírica, que conhece e utiliza, e uma prática consciente instaurada por uma linguagem por conhecimentos científicos. "( ) uno de los aspectos más positivos de las academias en lo siglo XVI fuera el de establecer una primera convencionlización del lenguage gráfico de la arquitectura de modo que se pudieran producir documentos más precisos y con ciertas comunes a todos los casos ( )" (Sainz, 90, 49). As artes do desenho são, na Academia, a pintura, a escultura e a arquitectura.

History & Info - Astronomical Basis Of Calendars, History In the great Basilica of San Petronio, a solar observatory was erected in 1576 byEgnatio danti, a mathematician and Dominican friar who worked for Cosimo I http://webexhibits.org/calendars/year-astronomy.html
Extractions: The principal astronomical cycles are the day (based on the rotation of the Earth on its axis), the year (based on the revolution of the Earth around the Sun), and the month (based on the revolution of the Moon around the Earth). The complexity of calendars arises because these cycles of revolution do not comprise an integral number of days, and because astronomical cycles are neither constant nor perfectly commensurable with each other. What are different measures of the year? How did Cassini prove Kepler was right? The tropical year is defined as the mean interval between vernal equinoxes; it corresponds to the cycle of the seasons. Our calendar year is linked to the tropical year as measured between two March equinoxes, as originally established by Caesar and Sosigenes. The following expression, based on the orbital elements of Laskar (1986), is used for calculating the length of the tropical year: 365.2421896698 - 0.00000615359 T - 7.29E-10 T
