Chérubin D'Orléans
Chérubin d'Orléans (1613-1697) was a French scientific instrument maker. Biography A Capucin father and distinguished physicist, Chérubin d'Orléans (François Lasséré) devoted himself to the study of optics and to vision-related problems, which he discussed in ''La dioptrique oculaire and La vision parfaite'' (Paris, 1671 and 1677 respectively). He developed a binocular telescope and he devised and may also have built a special type of eyepiece that replaced the lens with a short tube. Chérubin is also credited with producing models of the eyeball for studying the lens function of the eye. He also invented the stereo microscope, also called the dissecting microscope.

Chérubin Binocular Telescope-CnAM 12811-IMG 6439-white
''Chérubin'' is an opera (''comédie chantée'') in three acts by Jules Massenet to a French libretto by Francis de Croisset and Henri Cain after de Croisset's play of the same name. It was first performed at the Opéra de Monte-Carlo on 14 February 1905, with Mary Garden in the title role. The story is a light-hearted addition to Beaumarchais' Figaro plays, the action taking place soon after that of ''The Marriage of Figaro'', and imagines festivities in celebration of Chérubin's first military commission and seventeenth birthday. A farcical romp ensues, brought on by Chérubin lusting after each of the female characters and inspiring general confusion. Performance history The piece contains some of Massenet's most shimmering, charming music and has spawned a few contemporary revivals plus several recordings since 1980. The Royal Opera House in London premiered it on 14 February 1994 in a production starring Susan Graham in the title role. The performance was broadcast. Role ...

Order Of Friars Minor Capuchin
The Order of Friars Minor Capuchin (; postnominal abbr. O.F.M. Cap.) is a religious order of Franciscan friars within the Catholic Church, one of Three " First Orders" that reformed from the Franciscan Friars Minor Observant (OFM Obs., now OFM), the other being the Conventuals (OFM Conv.). Franciscans reformed as Capuchins in 1525 with the purpose of regaining the original Habit (Tunic) of St. Francis of Assisi and also for returning to a stricter observance of the rule established by Francis of Assisi in 1209. History Origins The Order arose in 1525 when Matteo da Bascio, an Observant Franciscan friar native to the Italian region of Marche, said he had been inspired by God with the idea that the manner of life led by the friars of his day was not the one which their founder, St. Francis of Assisi, had envisaged. He sought to return to the primitive way of life of solitude and penance, as practised by the founder of their Order. His religious superiors tried to suppress ...

Optics
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties. Most optical phenomena can be accounted for by using the classical electromagnetic description of light. Complete electromagnetic descriptions of light are, however, often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric optics, treats light as a collection of rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive model of light, which includes wave effects such as diffraction and interference that cannot be ...

Paris
Paris () is the capital and most populous city of France, with an estimated population of 2,165,423 residents in 2019 in an area of more than 105 km² (41 sq mi), making it the 30th most densely populated city in the world in 2020. Since the 17th century, Paris has been one of the world's major centres of finance, diplomacy, commerce, fashion, gastronomy, and science. For its leading role in the arts and sciences, as well as its very early system of street lighting, in the 19th century it became known as "the City of Light". Like London, prior to the Second World War, it was also sometimes called the capital of the world. The City of Paris is the centre of the Île-de-France region, or Paris Region, with an estimated population of 12,262,544 in 2019, or about 19% of the population of France, making the region France's primate city. The Paris Region had a GDP of €739 billion ($743 billion) in 2019, which is the highest in Europe. According to the Economist Intelli ...

Binocular Telescope
Binoculars or field glasses are two refracting telescopes mounted side-by-side and aligned to point in the same direction, allowing the viewer to use both eyes (binocular vision) when viewing distant objects. Most binoculars are sized to be held using both hands, although sizes vary widely from opera glasses to large pedestal-mounted military models. Unlike a (monocular) telescope, binoculars give users a three-dimensional image: each eyepiece presents a slightly different image to each of the viewer's eyes and the parallax allows the visual cortex to generate an impression of depth. Optical designs Galilean Almost from the invention of the telescope in the 17th century the advantages of mounting two of them side by side for binocular vision seems to have been explored. Most early binoculars used Galilean optics; that is, they used a convex objective and a concave eyepiece lens. The Galilean design has the advantage of presenting an erect image but has a narrow field of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Museo Galileo
Museo Galileo, the former ''Istituto e Museo di Storia della Scienza'' (Institute and Museum of the History of Science) is located in Florence, Italy, in Piazza dei Giudici, along the River Arno and close to the Uffizi Gallery. The museum, dedicated to astronomer and scientist Galileo Galilei, is housed in Palazzo Castellani, an 11th-century building which was then known as the Castello d’Altafronte. Museo Galileo owns one of the world's major collection of scientific instruments, which bears evidence of the role that the Medici and Lorraine Grand Dukes attached to science and scientists. The Museo di Storia della Scienza has re-opened to the public under the new name ''Museo Galileo'' since June 10, 2010, after a two-year closure due to redesigning and renovation works. It has been inaugurated four hundred years after the publication in March 1610 of Galileo's ''Sidereus Nuncius'' (''The Starry Messenger''). The museum The museum features the valuable scientific instruments fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
