Radcliffe Observatory
Radcliffe Observatory was the astronomical observatory of the University of Oxford from 1773 until 1934, when the Radcliffe Trustees sold it and built a new observatory in Pretoria, South Africa. It is a Grade I listed building. Today, the observatory forms a part of Green Templeton College of the University of Oxford. History The observatory was founded and named after John Radcliffe by the Radcliffe Trustees. It was built on the suggestion of the astronomer Thomas Hornsby, who was occupying the Savilian Chair of Astronomy, following his observation of the notable transit of Venus across the sun's disc in 1769 from a room in the nearby Radcliffe Infirmary. The observatory building commenced to designs by Henry Keene in 1772, and was completed in 1794 to the designs of James Wyatt, with a prominent octagonal tower based on the Tower of the Winds in Athens. Its tower is topped with a statue by John Bacon of Atlas holding up the World. Until 1839, the Savilian C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Observatory
An observatory is a location used for observing terrestrial, marine, or celestial events. Astronomy, climatology/meteorology, geophysical, oceanography and volcanology are examples of disciplines for which observatories have been constructed. Historically, observatories were as simple as containing an astronomical sextant (for measuring the distance between stars) or Stonehenge (which has some alignments on astronomical phenomena). Astronomical observatories Astronomical observatories are mainly divided into four categories: space-based, airborne, ground-based, and underground-based. Ground-based observatories Ground-based observatories, located on the surface of Earth, are used to make observations in the radio and visible light portions of the electromagnetic spectrum. Most optical telescopes are housed within a dome or similar structure, to protect the delicate instruments from the elements. Telescope domes have a slit or other opening in the roof that can be opened du ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Hornsby
Thomas Hornsby (1733 in Durham – 11 April 1810 in Oxford) was a British astronomer and mathematician. Life Hornsby became a Fellow of Corpus Christi College, Oxford in 1760. He occupied the Savilian Chair of Astronomy at Oxford University from 1763. In the same year, he became Sedleian Professor of Natural Philosophy. Hornsby was especially concerned with the observation of the transit of Venus. In 1761, he observed the transit of Venus from Shirburn Castle, in Oxfordshire, the seat of the Earl of Macclesfield. George Parker, 2nd Earl of Macclesfield (ca. 1695–1764), celebrated as an astronomer, had spent most of his time conducting astronomical observations at Shirburn Castle; here he had built an observatory and a chemical laboratory. Despite the international efforts made to observe the 1761 transit, poor weather conditions hampered observations. In 1766 Hornsby informed the Royal Society that preparations needed to begin for the 1769 transit, his publication in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

University Of London Observatory
UCL Observatory (called the University of London Observatory until 2015) at Mill Hill in London is an astronomical teaching observatory. It is part of the Department of Physics and Astronomy at University College London. History The Observatory was opened, as the University of London Observatory, on 8 October 1929 by the then Astronomer Royal Frank Watson Dyson, initially to house the 24-inch reflector built by Grubb of Dublin in 1881 and housed in Dr W.E. Wilson's observatory at Daramona, County Westmeath, Ireland, which was donated to the University of London after his death. An 8-inch refractor was installed in 1931 following its donation to the University by H.R. Fry of Barnett the previous year, and was named after him. In 1932, the University received a 6-inch refractor telescope from the estate of Mr. John Joynson of Liverpool. Although originally housed in the North dome in the Bloomsbury campus main quad, it was later relocated to the Observatory. In July 1938, the Ob ...

Museum Of The History Of Science, Oxford
The History of Science Museum in Broad Street, Oxford, England, holds a leading collection of scientific instruments from Middle Ages to the 19th century. The museum building is also known as the Old Ashmolean Building to distinguish it from the newer Ashmolean Museum building completed in 1894. The museum was built in 1683, and it is the world's oldest surviving purpose-built museum. History Built in 1683 to house Elias Ashmole's collection, the building was the world's first purpose-built museum building and was also open to the public. The original concept of the museum was to institutionalize the new learning about nature that appeared in the 17th century and experiments concerning natural philosophy were undertaken in a chemical laboratory in the basement, while lectures and demonstration took place in the School of Natural History, on the middle floor. Ashmole's collection was expanded to include a broad range of activities associated with the history of natural kno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South African Astronomical Observatory
South African Astronomical Observatory (SAAO) is the national centre for optical and infrared astronomy in South Africa. It was established in 1972. The observatory is run by the National Research Foundation of South Africa. The facility's function is to conduct research in astronomy and astrophysics.

George Henry Sacheverell Johnson
George Henry Sacheverell Johnson FRS (1808 – 5 November 1881) was a British clergyman and academic who was Dean of Wells and a professor at the University of Oxford. Life and career Johnson studied at The Queen's College, Oxford, winning a college scholarship, the Ireland scholarship and the university mathematics scholarship. He matriculated there in 1825, aged 17, graduating B.A. in 1829 with a first-class degree, and M.A. in 1833. He was a Fellow of the college from 1829 to 1855. Johnson was ordained into the Church of England in 1834 and elected as a Fellow of the Royal Society in 1838. He was appointed Savilian Professor of Astronomy in 1839, although his lack of astronomical knowledge led to the separation of the chair from the post of Radcliffe Observer. In 1842, he changed professorships to become White's Professor of Moral Philosophy, a post he held for three years. He advocated reform of Oxford and its colleges, an unpopular stance which he believed scuppered his ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlas (mythology)
In Greek mythology, Atlas (; grc-gre, Ἄτλας, ''Átlas'') is a Titan condemned to hold up the heavens or sky for eternity after the Titanomachy. Atlas also plays a role in the myths of two of the greatest Greek heroes: Heracles ( Hercules in Roman mythology) and Perseus. According to the ancient Greek poet Hesiod, Atlas stood at the ends of the earth in extreme west. Later, he became commonly identified with the Atlas Mountains in northwest Africa and was said to be the first King of Mauretania. Atlas was said to have been skilled in philosophy, mathematics, and astronomy. In antiquity, he was credited with inventing the first celestial sphere. In some texts, he is even credited with the invention of astronomy itself. Atlas was the son of the Titan Iapetus and the Oceanid Asia or Clymene. He was a brother of Epimetheus and Prometheus. He had many children, mostly daughters, the Hesperides, the Hyades, the Pleiades, and the nymph Calypso who lived on th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Bacon (sculptor, Born 1740)
John Bacon (24 November 1740 – 7 August 1799) was a British sculptor who worked in the late 18th century. Bacon has been reckoned the founder of the British School of sculpture. He won numerous awards, held the esteem of George III, and examples of his works adorn St Paul's Cathedral and Westminster Abbey in London, Christ Church, Oxford, Pembroke College, Oxford, Bath Abbey and Bristol Cathedral. Biography John Bacon was born in Southwark on 24 November 1740, the son of Thomas Bacon, a clothworker whose family had formerly held a considerable estate in Somersetshire. At the age of fourteen, John was apprenticed to Mr Crispe's porcelain manufactory at Lambeth, where he was at first employed in painting small ornamental pieces of china. He was swiftly promoted to modeller and used the additional income to support his parents, then in straitened circumstances. Observing the models sent by different eminent sculptors to be fired at the adjoining pottery kiln dete ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Athens
Athens ( ; el, Αθήνα, Athína ; grc, Ἀθῆναι, Athênai (pl.) ) is both the capital and largest city of Greece. With a population close to four million, it is also the seventh largest city in the European Union. Athens dominates and is the capital of the Attica region and is one of the world's oldest cities, with its recorded history spanning over 3,400 years and its earliest human presence beginning somewhere between the 11th and 7th millennia BC. Classical Athens was a powerful city-state. It was a centre for the arts, learning and philosophy, and the home of Plato's Academy and Aristotle's Lyceum. It is widely referred to as the cradle of Western civilization and the birthplace of democracy, largely because of its cultural and political influence on the European continent—particularly Ancient Rome. In modern times, Athens is a large cosmopolitan metropolis and central to economic, financial, industrial, maritime, political and cultural life in Gre ...

Tower Of The Winds
The Tower of the Winds or the Horologion of Andronikos Kyrrhestes is an octagonal Pentelic marble clocktower in the Roman Agora in Athens that functioned as a ''horologion'' or "timepiece". It is considered the world's first meteorological station. Unofficially, the monument is also called Aerides ( el, Αέρηδες), which means ''Winds''. The structure features a combination of sundials, a water clock, and a wind vane. It was designed by Andronicus of Cyrrhus around 50 BC, but according to other sources, might have been constructed in the 2nd century BC before the rest of the forum. The Athens Ephorate of Antiquities performed restoration work, cleaning and conserving the structure, between 2014 and 2016. Site The Tower of the Winds is tall and has a diameter of about . In antiquity it was topped by a weather vane-like Triton that indicated the wind direction. Below the frieze depicting the eight wind deities— Boreas (N), Kaikias (NE), Apeliotes (E), Eurus (SE), N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tower Of The Winds (Oxford)
The Tower of the Winds is the prominent octagonal tower on top of the old Radcliffe Observatory building in Oxford, England. The building now forms a centrepiece for Green Templeton College, one of the colleges of Oxford University. The tower is based on the ancient and smaller Tower of the Winds in Athens, Greece, built c.100–50 BC by Andronicus of Cyrrhus for the purpose of measuring time. It is of octagonal stone construction, with eight relief images of Greek mythological wind gods at the top of each side of the tower, carved by John Bacon the Elder in 1792–4. The tower was completed by James Wyatt in 1794. On the top are Atlas and Hercules supporting a globe in white, also by John Bacon. The reliefs of the signs of the zodiac above the windows on the first floor are made of Coade stone by J. C. F. Rossi. Inside the tower, there are three main rooms on top of each other.
