Auguste-Lucien Vérité
Auguste-Lucien Vérité (21 October 1806 – 19 July 1887) was a French clockmaker, the creator of the Besançon astronomical clock and the Beauvais astronomical clock. Vérité also did pioneering work on clock synchronisation. Working for the Chemins de fer du Nord railway company, he installed a clock network at Gare du Nord in Paris with all the station clocks regulated by electromagnetic impulse from a single master clock A master clock is a precision clock that provides timing signals to synchronise slave clocks as part of a clock network.

Beauvais
Beauvais ( , ; ) is a town and Communes of France, commune in northern France, and prefecture of the Oise Departments of France, département, in the Hauts-de-France Regions of France, region, north of Paris. The Communes of France, commune of Beauvais had a population of 56,020 , making it the most populous town in the Oise department, and third most populous in Picardy. Together with its suburbs and satellite towns, the metropolitan area of Beauvais has a population of 128,020. The region around Beauvais is called the Beauvaisis. History Beauvais was known to the Ancient Rome, Romans by the Gallo-Roman name of ''Caesaromagus'' (''magos'' is Common Celtic for "field"). The post-Renaissance Latin language, Latin rendering is ''Bellovacum'' from the Belgae, Belgic tribe the Bellovaci, whose capital it was. In the ninth century, it became a county (comté), which about 1013 passed to the bishops of Beauvais, who became peers of France from the twelfth century. This cites V. L ...

Besançon Astronomical Clock
Besançon (, ; , ; archaic ; ) is the capital of the department of Doubs in the region of Bourgogne-Franche-Comté. The city is located in Eastern France, close to the Jura Mountains and the border with Switzerland. Capital of the historic and cultural region of Franche-Comté, Besançon is home to the Bourgogne-Franche-Comté regional council headquarters, and is an important administrative centre in the region. It is also the seat of one of the fifteen French ecclesiastical provinces and one of the two divisions of the French Army. In 2022 the city had a population of 120,057, in a metropolitan area of 284,474, the second in the region in terms of population. Established in a meander of the river Doubs, the city was already important during the Gallo-Roman era under the name of ''Vesontio'', capital of the Sequani. Its geography and specific history turned it into a military stronghold, a garrison city, a political centre, and a religious capital. Besançon is the historic ...

Beauvais Astronomical Clock
The Beauvais Astronomical Clock is a nineteenth-century astronomical clock in Beauvais Cathedral in northern France.Michelin Green Guide to France. Michelin. 2010. History and description The clock was built between 1865 and 1868 by Auguste-Lucien Vérité. It is 12 metres high, and 6 metres wide. The 52 dials display the times of the rising and setting sun and moon, the position of the planets, the current time in 18 cities around the world, and the tidal times. The clock also displays the epact (i.e. age of the moon in days on January 1) and the golden number used in calculating the date of Easter. The hours and minutes are shown in the large central face which depicts Jesus Christ and the twelve apostles. An 1886 edition of '' Blackwood’s Edinburgh Magazine'' remarks that: "In the eyes of the neighbourhood the chief wonder of Beauvais is not the cathedral, but the astronomical clock...The mechanical part is admirable. It tells everything which any one can wish to know." ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Clock Network
A clock network or clock system is a set of synchronized clocks designed to always show exactly the same time by communicating with each other. Clock networks usually consist of a central master clock kept in sync with an official time source, and one or more slave clocks which receive and display the time from the master. Synchronization sources The master clock in a clock network can receive accurate time in a number of ways: through the United States GPS satellite constellation, a Network Time Protocol server, the CDMA cellular phone network, a modem connection to a time source, or by listening to radio transmissions from WWV or WWVH, or a special signal from an upstream broadcast network. Some master clocks don't determine the time automatically. Instead, they rely on an operator to manually set them. Clock networks in critical applications often include a backup source to receive the time, or provisions to allow the master clock to maintain the time even if it lose ...

Gare Du Nord
The Gare du Nord (; ), officially Paris Nord, is one of the seven large mainline railway station termini in Paris, France. The station is served by trains that run between the capital and northern France via the Paris–Lille railway, as well as to international destinations in Belgium, Germany, the Netherlands and the United Kingdom. Located in the northern part of Paris near the Gare de l'Est in the 10th arrondissement, the Gare du Nord offers connections with several urban transport lines, including Paris Métro, RER and buses. It is the busiest railway station in Europe by total passenger numbers. In 2015, the Gare du Nord saw more than 700,000 passengers per day. The current Gare du Nord was designed by French architect Jacques Ignace Hittorff, while the original complex was constructed between 1861 and 1864 on behalf of the Chemin de Fer du Nord company. The station replaced an earlier and much smaller terminal sharing the same name, which was operational between ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Master Clock
A master clock is a precision clock that provides timing signals to synchronise slave clocks as part of a clock network. Networks of electric clocks connected by wires to a precision master pendulum clock began to be used in institutions like factories, offices, and schools around 1900. Modern radio clocks are synchronised by radio signals or Internet connections to a worldwide time system called Coordinated Universal Time (UTC), which is governed by primary reference atomic clocks in many countries. A modern, atomic version of a master clock is the large clock ensemble found at the U.S. Naval Observatory. History Between the late 1800s and the availability of Internet time services, many large institutions that depended on accurate timekeeping such as schools, offices, railway networks, telephone exchanges, and factories used master/slave clock networks. These consisted of multiple slave clocks and other timing devices, connected through wires to a master clock whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
