Horological
Horology (; related to Latin '; ; , interfix ''-o-'', and suffix ''-logy''), . is the study of the measurement of time. Clocks, watches, clockwork, sundials, hourglasses, clepsydras, timers, time recorders, marine chronometers, and atomic clocks are all examples of instruments used to measure time. In current usage, horology refers mainly to the study of mechanical time-keeping devices, while chronometry more broadly includes electronic devices that have largely supplanted mechanical clocks for the best accuracy and precision in time-keeping. People interested in horology are called ''horologists''. That term is used both by people who deal professionally with timekeeping apparatuses (watchmakers, clockmakers), as well as aficionados and scholars of horology. Horology and horologists have numerous organizations, both professional associations and more scholarly societies. The largest horological membership organisation globally is the NAWCC, the National Association of Wat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clockmakers' Museum
The Clockmakers’ Museum in London, England, is believed to be the oldest collection specifically of clocks and watches in the world. The collection belongs to and is administered by the Clockmakers’ Charity, affiliated to the Worshipful Company of Clockmakers, founded in 1631 by Royal Charter. Since 2015 it has been housed in a gallery provided by the Science Museum in South Kensington, having formerly been located in the Guildhall complex in the City of London since 1874, where it first opened to the public. Admission is free. The formation of the collection dates back to 1814. The principal goal of the museum is to educate the public about the history of the field of clock and watchmaking (horology), principally in the City of London, and also to promote education and career possibilities in the craft of horology, which as of 2019 was placed on the HCA Red List of Endangered Crafts. The Archive of the Clockmakers is managed on its behalf by the London Metropolitan Archive a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Horological Institute
The British Horological Institute (BHI) is the representative body of the horological industry in the United Kingdom. It was founded by a group of clockmakers in 1858, and has its current premises at Upton Hall in Nottinghamshire, which includes a museum of clock history. History The BHI was founded in 1858 by a small group of clockmakers, one of whom was Edward Daniel Johnson. Their aim was to unify the British horological industry and trades in the face of large numbers of imports of clocks and watches from abroad. The institute was an immediate success and within a year it had founded its own museum and library; it also began to offer evening classes in clock- and watch-making. The journal of the institute is the ''Horological Journal'', which has been published monthly since September 1858. It is claimed to be the oldest continuously published technical journal in the world. Upton Hall The current premises of the BHI are at Upton Hall in Nottinghamshire, England. Its prim ...

Marine Chronometer
A marine chronometer is a precision timepiece that is carried on a ship and employed in the determination of the ship's position by celestial navigation. It is used to determine longitude by comparing Greenwich Mean Time (GMT), or in the modern world its successor Coordinated Universal Time (UTC), and the time at the current location found from observations of celestial bodies. When first developed in the 18th century, it was a major technical achievement, as accurate knowledge of the time over a long sea voyage was vital for effective navigation, lacking electronic or communications aids. The first true chronometer was the life work of one man, John Harrison, spanning 31 years of persistent experimentation and testing that revolutionized naval (and later aerial) navigation and enabling the Age of Discovery and Colonialism to accelerate. The term ''chronometer'' was coined from the Greek words '' χρόνος (chronos)'' (meaning time) and ''meter'' (meaning measure) in 1713 by ...

Guildhall Library
The Guildhall Library is a public reference library specialising in subjects relevant to London. It is administered by the Corporation of London, the government of the City of London, which is the historical heart of London, England. The library was founded in the 1420s under the terms of the will of Lord Mayor Dick Whittington. Many volumes in store rooms were lost due to bombing in World War Two. The library was originally housed in the Old Library at the Guildhall, and moved to modern premises elsewhere in the Guildhall complex in the 1970s. Services The library is a public reference library and specialises in subjects relevant to London. The collection has its greatest depth on topics specifically concerned with the City, but also contains a great deal of material on the other parts of metropolitan London. It is divided into three main sections: printed books; manuscripts; and prints, maps and drawings. The material dates from the eleventh century onwards. Notable librari ...

Sundial
A sundial is a horological device that tells the time of day (referred to as civil time in modern usage) when direct sunlight shines by the apparent position of the Sun in the sky. In the narrowest sense of the word, it consists of a flat plate (the ''dial'') and a gnomon, which casts a shadow onto the dial. As the Sun appears to move through the sky, the shadow aligns with different hour-lines, which are marked on the dial to indicate the time of day. The ''style'' is the time-telling edge of the gnomon, though a single point or ''nodus'' may be used. The gnomon casts a broad shadow; the shadow of the style shows the time. The gnomon may be a rod, wire, or elaborately decorated metal casting. The style must be parallel to the axis of the Earth's rotation for the sundial to be accurate throughout the year. The style's angle from horizontal is equal to the sundial's geographical latitude. The term ''sundial'' can refer to any device that uses the Sun's altitude or azimut ...

British Museum
The British Museum is a public museum dedicated to human history, art and culture located in the Bloomsbury area of London. Its permanent collection of eight million works is among the largest and most comprehensive in existence. It documents the story of human culture from its beginnings to the present.Among the national museums in London, sculpture and decorative and applied art are in the Victoria and Albert Museum; the British Museum houses earlier art, non-Western art, prints and drawings. The National Gallery holds the national collection of Western European art to about 1900, while art of the 20th century on is at Tate Modern. Tate Britain holds British Art from 1500 onwards.

Royal Greenwich Observatory
The Royal Observatory, Greenwich (ROG; known as the Old Royal Observatory from 1957 to 1998, when the working Royal Greenwich Observatory, RGO, temporarily moved south from Greenwich to Herstmonceux) is an observatory situated on a hill in Greenwich Park in south east London, overlooking the River Thames to the north. It played a major role in the history of astronomy and navigation, and because the Prime Meridian passes through it, it gave its name to Greenwich Mean Time, the precursor to today's Coordinated Universal Time (UTC). The ROG has the IAU observatory code of 000, the first in the list. ROG, the National Maritime Museum, the Queen's House and the clipper ship ''Cutty Sark'' are collectively designated Royal Museums Greenwich. The observatory was commissioned in 1675 by King Charles II, with the foundation stone being laid on 10 August. The old hilltop site of Greenwich Castle was chosen by Sir Christopher Wren, a former Savilian Professor of Astronomy; as Greenwi ...

Cuckooland Museum
The Cuckooland Museum, previously known as the ''Cuckoo Clock Museum'', is a museum that exhibits mainly cuckoo clocks, located in Tabley, Cheshire, England. The collection comprises 300 years of cuckoo clock-making history, since the very earliest examples made in the 18th to the 21st century. Establishment and foundational reasons The museum was set up in 1990 by brothers Roman and Maz Piekarski after bringing together a collection of antique Black Forest cuckoo clocks that has been continuously increased ever since. Both men were trained as clockmakers in Manchester from the age of 15, which is when their fascination with these timepieces began. It became apparent to them that an important part of European clock-making history was liable to disappear if surviving examples fell into irretrievable disrepair. Their guiding principles have always been to purchase objects only of the highest museum quality and which held an important significance in the historical development of ...
