Gerald Hawkins
Gerald Stanley Hawkins (20 April 1928– 26 May 2003) was a British-born American astronomer and author noted for his work in the field of archaeoastronomy. A professor and chair of the astronomy department at Boston University in the United States, he published in 1963 an analysis of Stonehenge in which he was the first to propose that it was an ancient astronomical observatory used to predict movements of the sun and moon, and that it was used as a computer. Archaeologists and other scholars have since demonstrated such sophisticated, complex planning and construction at other prehistoric earthwork sites, such as Cahokia in the United States. Early life and education Gerald Hawkins was born in Great Yarmouth, England and studied physics and mathematics at the University of Nottingham. In 1952 he took a PhD in radio astronomy, studying under Sir Bernard Lovell at the University of Manchester. Career In 1957 Hawkins became professor of astronomy and chairman of the depa ...

Great Yarmouth
Great Yarmouth (), often called Yarmouth, is a seaside town and unparished area in, and the main administrative centre of, the Borough of Great Yarmouth in Norfolk, England; it straddles the River Yare and is located east of Norwich. A population of 38,693 in the 2011 Census made it Norfolk's third most populous. Its fishing industry, mainly for herring, shrank after the mid-20th century and has all but ended. North Sea oil from the 1960s supplied an oil-rig industry that services offshore natural gas rigs; more recently, offshore wind power and other renewable energy industries have ensued. Yarmouth has been a resort since 1760 and a gateway from the Norfolk Broads to the North Sea. Holiday-making rose when a railway opened in 1844, bringing easier, cheaper access and some new settlement. Wellington Pier opened in 1854 and Britannia Pier in 1858. Through the 20th century, Yarmouth boomed as a resort, with a promenade, pubs, trams, fish-and-chip shops, theatres, the Pleasu ...

Tektite
Tektites (from grc, τηκτός , meaning 'molten') are gravel-sized bodies composed of black, green, brown or grey natural glass formed from terrestrial debris ejected during meteorite impacts. The term was coined by Austrian geologist Franz Eduard Suess (1867–1941), son of Eduard Suess. They generally range in size from millimetres to centimetres. Millimetre-scale tektites are known as microtektites.French, B. M. (1998) ''Traces of Catastrophe: A Handbook of Shock-Metamorphic Effects in Terrestrial Meteorite Impact Structures.''

American Astronomical Society
The American Astronomical Society (AAS, sometimes spoken as "double-A-S") is an American society of professional astronomers and other interested individuals, headquartered in Washington, DC. The primary objective of the AAS is to promote the advancement of astronomy and closely related branches of science, while the secondary purpose includes enhancing astronomy education and providing a political voice for its members through lobbying and grassroots activities. Its current mission is to enhance and share humanity's scientific understanding of the universe as a diverse and inclusive astronomical community. History The society was founded in 1899 through the efforts of George Ellery Hale. The constitution of the group was written by Hale, George Comstock, Edward Morley, Simon Newcomb and Edward Charles Pickering. These men, plus four others, were the first Executive Council of the society; Newcomb was the first president. The initial membership was 114. The AAS name of the so ...

Karnak
The Karnak Temple Complex, commonly known as Karnak (, which was originally derived from ar, خورنق ''Khurnaq'' "fortified village"), comprises a vast mix of decayed temples, pylons, chapels, and other buildings near Luxor, Egypt. Construction at the complex began during the reign of Senusret I (reigned 1971–1926 BCE) in the Middle Kingdom (around 2000–1700 BCE) and continued into the Ptolemaic Kingdom (305–30 BCE), although most of the extant buildings date from the New Kingdom. The area around Karnak was the ancient Egyptian ''Ipet-isut'' ("The Most Selected of Places") and the main place of worship of the 18th Dynastic Theban Triad, with the god Amun as its head. It is part of the monumental city of Thebes, and in 1979 it was inscribed on the UNESCO World Heritage List along with the rest of the city. The Karnak complex gives its name to the nearby, and partly surrounded, modern village of El-Karnak, north of Luxor. Overview The complex is a vast open site an ...

Amun
Amun (; also ''Amon'', ''Ammon'', ''Amen''; egy, jmn, reconstructed as (Old Egyptian and early Middle Egyptian) → (later Middle Egyptian) → (Late Egyptian), cop, Ⲁⲙⲟⲩⲛ, Amoun) romanized: ʾmn) was a major ancient Egyptian deity who appears as a member of the Hermopolitan Ogdoad. Amun was attested from the Old Kingdom together with his wife Amunet. With the 11th Dynasty ( 21st century BC), Amun rose to the position of patron deity of Thebes by replacing Montu. After the rebellion of Thebes against the Hyksos and with the rule of Ahmose I (16th century BC), Amun acquired national importance, expressed in his fusion with the Sun god, Ra, as Amun-Ra (alternatively spelled Amon-Ra or Amun-Re). Amun-Ra retained chief importance in the Egyptian pantheon throughout the New Kingdom (with the exception of the " Atenist heresy" under Akhenaten). Amun-Ra in this period (16th to 11th centuries BC) held the position of transcendental, self-created creator dei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nazca Lines
The Nazca Lines are a group of geoglyphs made in the soil of the Nazca Desert in southern Peru. They were created between 500 BCE and 500 CE by people making depressions or shallow incisions in the desert floor, removing pebbles and leaving differently colored dirt exposed. There are two major phases of the Nazca lines, Paracas phase, from 400 to 200 BCE, and Nazca phase, from 200 BCE to 500 CE. In the years leading up to 2020, between 80 and 100 new figures had been found with the use of drones, and archaeologists believe that there are more to be found. Most lines run straight across the landscape, but there are also figurative designs of animals and plants. The individual figurative geoglyph designs measure between across. The combined length of all the lines is more than , and the group covers an area of about . The lines are typically deep. They were made by removing the top layer of reddish-brown iron oxide-coated pebbles to reveal a yellow-grey subsoil. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snake Mound
Snakes are elongated, limbless, carnivorous reptiles of the suborder Serpentes . Like all other squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales. Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads (cranial kinesis). To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have evolved elongate bodies without limbs or with greatly reduced limbs about twenty-five times independently via convergent evolution, leading to many lineages of legless lizards. These resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, although this rule is not universal (see Amphisbaenia, Dibamida ...

Alexander Thom
Alexander Thom (26 March 1894 – 7 November 1985) was a Scottish engineer most famous for his theory of the Megalithic yard, categorisation of stone circles and his studies of Stonehenge and other archaeological sites. Life and work Early life and education Thom was born in Carradale in 1894 to Archibald Thom, a tenant farmer at ''Mains farm'' for Carradale House, and his wife Lily Stevenson Strang from the family of Robert Louis Stevenson. Her mother (Thom's grandmother) belonged to a large family from Symington, upon whom had been bestowed the land by Robert the Bruce. His father trained the Church choir while his mother was pianist. Thom spent his early years at Mains farm until moving to ''The Hill'' farm at Dunlop, Ayrshire. Instilled with a good work ethic by his father, Thom taught himself industrial engineering and entered college in Glasgow in 1911 where he studied alongside John Logie Baird. In 1912 he attended summer school at Loch Eck where he was trained in s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard J
Richard is a male given name. It originates, via Old French, from Old Frankish and is a compound of the words descending from Proto-Germanic ''*rīk-'' 'ruler, leader, king' and ''*hardu-'' 'strong, brave, hardy', and it therefore means 'strong in rule'. Nicknames include "Richie", "Dick", "Dickon", " Dickie", "Rich", "Rick", "Rico", "Ricky", and more. Richard is a common English, German and French male name. It's also used in many more languages, particularly Germanic, such as Norwegian, Danish, Swedish, Icelandic, and Dutch, as well as other languages including Irish, Scottish, Welsh and Finnish. Richard is cognate with variants of the name in other European languages, such as the Swedish "Rickard", the Catalan "Ricard" and the Italian "Riccardo", among others (see comprehensive variant list below). People named Richard Multiple people with the same name * Richard Andersen (other) * Richard Anderson (other) * Richard Cartwright (other) * Ri ...

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 during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM 7090
The IBM 7090 is a second-generation transistorized version of the earlier IBM 709 vacuum tube mainframe computer that was designed for "large-scale scientific and technological applications". The 7090 is the fourth member of the IBM 700/7000 series scientific computers. The first 7090 installation was in December 1959. In 1960, a typical system sold for $2.9 million (equivalent to $ million in ) or could be rented for $63,500 a month (). The 7090 uses a 36-bit word length, with an address space of 32,768 words (15-bit addresses). It operates with a basic memory cycle of 2.18 μs, using the IBM 7302 Core Storage core memory technology from the IBM 7030 (Stretch) project. With a processing speed of around 100 Kflop/s, the 7090 is six times faster than the 709, and could be rented for half the price. An upgraded version, the 7094 was up to twice as fast. Both the 7090 and the 7094 were withdrawn from sale on July 14, 1969, but systems remained in service for more than a deca ...
