Antoine Claudet
Ada Byron's daguerreotype by Claudet, . Antoine François Jean Claudet (August 18, 1797 – December 27, 1867) was a French photographer and artist active in London who produced daguerreotypes. Early Years Claudet was born in La Croix-Rousse, France, the son of Claude Claudet, a cloth merchant and Etiennette Julie Montagnat. Career Early in his career Claudet headed a glass factory at Choisy-le-Roi, Paris, together with Georges Bontemps, and moved to England to promote the factory with a shop in High Holborn, London. Having acquired a share in L. J. M. Daguerre's invention, he became one of England's first commercial photographers using the daguerreotype process for portraiture, improving the sensitizing process by using chlorine (instead of bromine) in addition to iodine, thus gaining greater rapidity of action. He invented the red darkroom safelight, and it was he who suggested the idea of using a series of photographs to create the illusion of movement. The idea of us ...

Bromine
Bromine is a chemical element with the symbol Br and atomic number 35. It is the third-lightest element in group 17 of the periodic table (halogens) and is a volatile red-brown liquid at room temperature that evaporates readily to form a similarly coloured vapour. Its properties are intermediate between those of chlorine and iodine. Isolated independently by two chemists, Carl Jacob Löwig (in 1825) and Antoine Jérôme Balard (in 1826), its name was derived from the Ancient Greek (bromos) meaning "stench", referring to its sharp and pungent smell. Elemental bromine is very reactive and thus does not occur as a native element in nature but it occurs in colourless soluble crystalline mineral halide salts, analogous to table salt. In fact, bromine and all the halogens are so reactive that they form bonds in pairs—never in single atoms. While it is rather rare in the Earth's crust, the high solubility of the bromide ion (Br) has caused its accumulation in the oceans. Commercial ...

Māori People
The Māori (, ) are the indigenous Polynesian people of mainland New Zealand (). Māori originated with settlers from East Polynesia, who arrived in New Zealand in several waves of canoe voyages between roughly 1320 and 1350. Over several centuries in isolation, these settlers developed their own distinctive culture, whose language, mythology, crafts, and performing arts evolved independently from those of other eastern Polynesian cultures. Some early Māori moved to the Chatham Islands, where their descendants became New Zealand's other indigenous Polynesian ethnic group, the Moriori. Initial contact between Māori and Europeans, starting in the 18th century, ranged from beneficial trade to lethal violence; Māori actively adopted many technologies from the newcomers. With the signing of the Treaty of Waitangi in 1840, the two cultures coexisted for a generation. Rising tensions over disputed land sales led to conflict in the 1860s, and massive land confiscations, to which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photograph
A photograph (also known as a photo, image, or picture) is an image created by light falling on a photosensitive surface, usually photographic film or an electronic image sensor, such as a CCD or a CMOS chip. Most photographs are now created using a smartphone/camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would see. The process and practice of creating such images is called photography. Etymology The word ''photograph'' was coined in 1839 by Sir John Herschel and is based on the Greek φῶς (''phos''), meaning "light," and γραφή (''graphê''), meaning "drawing, writing," together meaning "drawing with light." History The first permanent photograph, a contact-exposed copy of an engraving, was made in 1822 using the bitumen-based "heliography" process developed by Nicéphore Niépce. The first photographs of a real-world scene, made using a camera obscura, followed a few years later at Le Gras, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hemi Pomara
Hemi Pomara (born c. 1830; sometimes spelled Pomare) was a Māori man of chiefly status, from the Chatham Islands. In his youth, he was taken to Sydney, and then London, before returning to New Zealand, via Barbados, where he was shipwrecked. A daguerreotype of Pomara is the oldest known photograph of any Māori person. A novel and a planned film are based on his life. Early life Hemi Pomara was born in around 1830, the grandson of Wiremu Piti Pomara, a Māori chief of the Ngāti Mutunga, an (tribe) on the Chatham Islands ( mi, Wharekauri). His family were massacred by a rival tribe, leaving him an orphan. Sydney In late 1844, Pomara was taken on the brig ''Coolangatta'' to Sydney, the capital of the then Colony of New South Wales, by the artist George French Angas, who became his guardian. While there he attended an English boarding school. Angas took Pomara with him as he gave lectures in New South Wales and the neighbouring Province of South Australia, and painted a ...

Charles Babbage
Charles Babbage (; 26 December 1791 – 18 October 1871) was an English polymath. A mathematician, philosopher, inventor and mechanical engineer, Babbage originated the concept of a digital programmable computer. Babbage is considered by some to be " father of the computer". Babbage is credited with inventing the first mechanical computer, the Difference Engine, that eventually led to more complex electronic designs, though all the essential ideas of modern computers are to be found in Babbage's Analytical Engine, programmed using a principle openly borrowed from the Jacquard loom. Babbage had a broad range of interests in addition to his work on computers covered in his book ''Economy of Manufactures and Machinery''. His varied work in other fields has led him to be described as "pre-eminent" among the many polymaths of his century. Babbage, who died before the complete successful engineering of many of his designs, including his Difference Engine and Analytical Eng ...

Michael Faraday
Michael Faraday (; 22 September 1791 – 25 August 1867) was an English scientist who contributed to the study of electromagnetism and electrochemistry. His main discoveries include the principles underlying electromagnetic induction, diamagnetism and electrolysis. Although Faraday received little formal education, he was one of the most influential scientists in history. It was by his research on the magnetic field around a conductor carrying a direct current that Faraday established the concept of the electromagnetic field in physics. Faraday also established that magnetism could affect rays of light and that there was an underlying relationship between the two phenomena.. the 1911 Encyclopædia Britannica. He similarly discovered the principles of electromagnetic induction, diamagnetism, and the laws of electrolysis. His inventions of electromagnetic rotary devices formed the foundation of electric motor technology, and it was largely due to his efforts t ...

Regent Street
Regent Street is a major shopping street in the West End of London. It is named after George, the Prince Regent (later George IV) and was laid out under the direction of the architect John Nash and James Burton. It runs from Waterloo Place in St James's at the southern end, through Piccadilly Circus and Oxford Circus, to All Souls Church. From there Langham Place and Portland Place continue the route to Regent's Park. The street's layout was completed in 1825 and was an early example of town planning in England, replacing earlier roads including Swallow Street. Nash and Burton's street layout has survived, although all the original buildings except All Souls Church have been replaced following reconstruction in the late 19th century. The street is known for its flagship retail stores, including Liberty, Hamleys, Jaeger and the Apple Store. The Royal Polytechnic Institution, now the University of Westminster, has been based on Regent Street since 1838. Route Regent Str ...

Regent's Park
Regent's Park (officially The Regent's Park) is one of the Royal Parks of London. It occupies of high ground in north-west Inner London, administratively split between the City of Westminster and the Borough of Camden (and historically between Marylebone and Saint Pancras parishes). In addition to its large central parkland and ornamental lake, it contains various structures and organizations both public and private, generally on its periphery, including Regent's University and London Zoo. What is now Regent's Park came into possession of the Crown upon the dissolution of the monasteries in the 1500s, and was used for hunting and tenant farming. In the 1810s, the Prince Regent proposed turning it into a pleasure garden. The park was designed by John Nash and James and Decimus Burton. Its construction was financed privately by James Burton after the Crown Estate rescinded its pledge to do so, and included development on the periphery of townhouses and expensive terrace dw ...

Ada Lovelace
Augusta Ada King, Countess of Lovelace (''née'' Byron; 10 December 1815 – 27 November 1852) was an English mathematician and writer, chiefly known for her work on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine. She was the first to recognise that the machine had applications beyond pure calculation, and to have published the first algorithm intended to be carried out by such a machine. As a result, she is often regarded as the first computer programmer. Ada Byron was the only legitimate child of poet Lord Byron and Lady Byron. All of Byron's other children were born out of wedlock to other women. Byron separated from his wife a month after Ada was born and left England forever. Four months later, he commemorated the parting in a poem that begins, "Is thy face like thy mother's my fair child! ADA! sole daughter of my house and heart?" He died in Greece when Ada was eight. Her mother remained bitter and promoted Ada's interest i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
