Giovanni Caselli
Giovanni Caselli (8 June 1815 – 25 April 1891) was an Italian priest, inventor, and physicist. He studied electricity and magnetism as a child which led to his invention of the pantelegraph (also known as the universal telegraph or all-purpose telegraph), the forerunner of the fax machine. The world's first practical operating facsimile machine ("fax") system put into use was by Caselli. He had worldwide patents on his system. His technology idea was further developed into today's analog television. Caselli was a student and professor at the University of Florence in Italy. He started a technical journal that explained physics in layman's terms. For his pantelegraph technology he was awarded the Legion of Honor by Napoleon III of France. Parisian scientists and engineers started the Pantelegraph Society to exchange ideas about the pantelegraph and the associated synchronizing apparatus, in order to get the sending and receiving mechanisms to work together properly.

Siena, Italy
Siena ( , ; lat, Sena Iulia) is a city in Tuscany, Italy. It is the capital of the province of Siena. The city is historically linked to commercial and banking activities, having been a major banking center until the 13th and 14th centuries. Siena is also home to the oldest bank in the world, the Monte dei Paschi bank, which has been operating continuously since 1472. Several significant Renaissance painters worked and were born in Siena, among them Duccio, Ambrogio Lorenzetti, Simone Martini and Sassetta, and influenced the course of Italian and European art. The University of Siena, originally called ''Studium Senese'', was founded in 1240, making it one of the oldest universities in continuous operation in the world. Siena was one of the most important cities in medieval Europe, and its historic centre is a UNESCO World Heritage Site. From January until the end of September of 2021 it had about 217,000 arrivals, with the largest numbers of foreign visitors coming ...

Insurrection
Rebellion, uprising, or insurrection is a refusal of obedience or order. It refers to the open resistance against the orders of an established authority. A rebellion originates from a sentiment of indignation and disapproval of a situation and then manifests itself by the refusal to submit or to obey the authority responsible for this situation. Rebellion can be individual or collective, peaceful (civil disobedience, civil resistance, and nonviolent resistance) or violent (terrorism, sabotage and guerrilla warfare). In political terms, rebellion and revolt are often distinguished by their different aims. While rebellion generally seeks to evade and/or gain concessions from an oppressive power, a revolt seeks to overthrow and destroy that power, as well as its accompanying laws. The goal of rebellion is resistance while a revolt seeks a revolution. As power shifts relative to the external adversary, or power shifts within a mixed coalition, or positions harden or soften on eithe ...

Leopold II, Grand Duke Of Tuscany
Leopold II( it, Leopoldo Giovanni Giuseppe Francesco Ferdinando Carlo, german: Leopold Johann Joseph Franz Ferdinand Karl, English: ''Leopold John Joseph Francis Ferdinand Charles''. (3 October 1797 – 29 January 1870) was Grand Duke of Tuscany from 1824 to 1859. He married twice; first to Maria Anna of Saxony, and after her death in 1832, to Maria Antonia of the Two-Sicilies. By the latter, he begat his eventual successor, Ferdinand. Leopold was recognised contemporarily as a liberal monarch, authorising the Tuscan Constitution of 1848, and allowing a degree of press freedom. The Grand Duke was deposed briefly by a provisional government in 1849, only to be restored the same year with the assistance of Austrian troops, who occupied the state until 1855. Leopold attempted a policy of neutrality with regard to the Second Italian War of Independence, but was expelled by a bloodless coup on 27 April 1859, just before the beginning of the war. The Grand Ducal family left for B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Newspapers
A newspaper is a periodical publication containing written information about current events and is often typed in black ink with a white or gray background. Newspapers can cover a wide variety of fields such as politics, business, sports and art, and often include materials such as opinion columns, weather forecasts, reviews of local services, obituaries, birth notices, crosswords, editorial cartoons, comic strips, and advice columns. Most newspapers are businesses, and they pay their expenses with a mixture of subscription revenue, newsstand sales, and advertising revenue. The journalism organizations that publish newspapers are themselves often metonymically called newspapers. Newspapers have traditionally been published in print (usually on cheap, low-grade paper called newsprint). However, today most newspapers are also published on websites as online newspapers, and some have even abandoned their print versions entirely. Newspapers developed in the 17th ...

Stylus
A stylus (plural styli or styluses) is a writing utensil or a small tool for some other form of marking or shaping, for example, in pottery. It can also be a computer accessory that is used to assist in navigating or providing more precision when using touchscreens. It usually refers to a narrow elongated staff, similar to a modern ballpoint pen. Many styluses are heavily curved to be held more easily. Another widely used writing tool is the stylus used by blind users in conjunction with the slate for punching out the dots in Braille. Etymology The English word ''stylus'' has two plurals: ''styli'' and ''styluses''. The original Latin word was spelled ; the spelling ''stylus'' arose from an erroneous connection with Greek (), 'pillar'.'' Oxford Latin Dictionary'', s.v. "stilus" (2012). The Latin word had several meanings, including "a long, sharply pointed piece of metal; the stem of a plant; a pointed instrument for incising letters; the stylus (as used in literary co ...

Tin Foil
Tin foil, also spelled tinfoil, is a thin foil made of tin. Tin foil was superseded after World War II by cheaper and more durable aluminium foil, which is still referred to as "tin foil" in many regions (an example of a misnomer). History Foil made from a thin leaf of tin was commercially available before its aluminium counterpart. In the late 19th century and early 20th century, tin foil was in common use, and some people continue to refer to the new product by the name of the old one. Tin foil is stiffer than aluminium foil. It tends to give a slight tin taste to food wrapped in it, which is a major reason it has largely been replaced by aluminium and other materials for wrapping food. Because of its corrosion resistance, oxidation resistance, availability, low cost, low toxicity, and slight malleability, tin foil was used as a filling for tooth cavities prior to the 20th century. The first audio recordings on phonograph cylinder Phonograph cylinders are the earlie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frederick Bakewell
Frederick Collier Bakewell (29 September 1800 – 26 September 1869) was an English physicist who improved on the concept of the facsimile machine introduced by Alexander Bain in 1842 and demonstrated a working laboratory version at the 1851 World's Fair in London. Biography Born in Wakefield, West Yorkshire, he eventually moved to Hampstead, Middlesex where he lived until his death. He is buried in a family grave in Kensal Green Cemetery. Bakewell was married to Henrietta Darbyshire with whom he had two sons, Robert and Armitage. Image telegraph Bakewell's "image telegraph" had many of the features of modern facsimile machines, and replaced the pendulums of Bain's system with synchronized rotating cylinders. The system involved writing or drawing on a piece of metal foil with a special insulating ink; the foil was then wrapped around a cylinder which slowly rotated, driven by a clock mechanism. A metal stylus driven by a screw thread traveled across the surface of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexander Bain (inventor)
Alexander Bain (12 October 1810 – 2 January 1877) was a Scottish inventor and engineer who was first to invent and patent the electric clock. He invented the Telegraph Clock, which was a technology of synchronizing many electric clocks placed anywhere in the world; they would all have the exact same time. He also invented and patented the technology of the facsimile machine for scanning images and transmitting them across telegraph lines hundreds of miles away. He installed the railway telegraph lines between Edinburgh and Glasgow, Scotland, for recording messages, to regulate the safe movement of trains, marking time, giving signals, and printing information at different locations. He invented a chemical telegraph technology of being able to transmit across a telegraph line messages at up to 1000 words per minute, while at the time Morse's telegraph could only produce 40 words a minute. Early life Bain was born in Houstry, near Watten, Caithness, Scotland. He was born o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Layman
In religious organizations, the laity () consists of all members who are not part of the clergy, usually including any non-ordained members of religious orders, e.g. a nun or a lay brother. In both religious and wider secular usage, a layperson (also layman or laywoman) is a person who is not qualified in a given profession or does not have specific knowledge of a certain subject. The phrase " layman's terms" is used to refer to plain language that is understandable to the everyday person, as opposed to specialised terminology understood only by a professional. Some Christian churches utilise lay preachers, who preach but are not clergy. The Church of Jesus Christ of Latter-day Saints uses the term ''lay priesthood'' to emphasise that its local congregational leaders are unpaid. Terms such as ''lay priest'', ''lay clergy'' and ''lay nun'' were once used in certain Buddhist cultures to indicate ordained persons who continued to live in the wider community instead of retirin ...
