Brown University
Brown University is a private research university in Providence, Rhode Island. Brown is the seventh-oldest institution of higher education in the United States, founded in 1764 as the College in the English Colony of Rhode Island and Providence Plantations. Brown is one of nine colonial colleges chartered before the American Revolution. Admissions at Brown is among the most selective in the United States. In 2022, the university reported a first year acceptance rate of 5%. It is a member of the Ivy League. Brown was the first college in the United States to codify in its charter that admission and instruction of students was to be equal regardless of their religious affiliation. The university is home to the oldest applied mathematics program in the United States, the oldest engineering program in the Ivy League, and the third-oldest medical program in New England. The university was one of the early doctoral-granting U.S. institutions in the late 19th century, adding masters ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lockheed F-104 Starfighter
The Lockheed F-104 Starfighter is an American single-engine, supersonic air superiority fighter which was extensively deployed as a fighter-bomber during the Cold War. Created as a day fighter by Lockheed as one of the "Century Series" of fighter aircraft for the United States Air Force (USAF), it was developed into an all-weather multirole aircraft in the early 1960s and produced by several other nations, seeing widespread service outside the United States. After a series of interviews with Korean War fighter pilots in 1951, Kelly Johnson, then lead designer at Lockheed, opted to reverse the trend of ever-larger and more complex fighters and produce a simple, lightweight aircraft with maximum altitude and climb performance. On 4 March 1954, the Lockheed XF-104 took to the skies for the first time, and on 26 February 1958 the production fighter was activated by the USAF. Only a few months later it was pressed into action during the Second Taiwan Strait Crisis, when it was de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Benjamin West (astronomer)
Benjamin West (March 1730 – August 26, 1813) was an American astronomer, mathematician, professor, and author of almanacs. Life and work Born in Rehoboth, Massachusetts, Benjamin West was largely an autodidact. After a school he started in Providence, Rhode Island about 1753 proved unprofitable, he opened a dry-goods store and added what is thought to have been the first bookstore in Providence. He closed his store and made clothes for soldiers during the American Revolutionary War. Immediately after the war West opened another school in Providence and then taught at Philadelphia's new Protestant Episcopal Academy from 1787 to 1788. In 1786 he was appointed Professor of Mathematics and Astronomy at Rhode Island College (now known as Brown University), and assumed this position in 1788. He taught mathematics and astronomy at Rhode Island College until 1799. Upon leaving Rhode Island College West moved to Newport to start a school of navigation in his home. From 1802 ...

Uccle
Uccle () or Ukkel () is one of the 19 municipalities of the Brussels-Capital Region, Belgium. In common with all of Brussels' municipalities, it is legally bilingual (French–Dutch). It is generally considered an affluent area of the city and is particularly noted for its community of French immigrants. History According to legend, Uccle's church of St. Peter was dedicated by Pope Leo III in the year 803, with Charlemagne and Gerbald, Bishop of Liège, attending the ceremony. During the following centuries, several noble families built their manors and took residency there. The first mention of the name ''Woluesdal'', now evolved into ''Wolvendael'', dates from 1209. In 1467, Isabella of Portugal, wife of Philip the Good, Duke of Burgundy, founded a Franciscan convent on Uccle's territory. Later, Uccle became the judiciary capital of the area including Brussels.

Royal Observatory Of Belgium
The Royal Observatory of Belgium (french: link=no, Observatoire Royal de Belgique, nl, Koninklijke Sterrenwacht van België), has been situated in the Uccle municipality of Brussels (Belgium) since 1890. It was first established in Saint-Josse-ten-Noode in 1826 by William I under the impulse of Adolphe Quetelet. It was home to a diameter aperture Zeiss reflector in the first half of the 20th century, one of the largest telescopes in the world at the time. It owns a variety of other astronomical instruments, such as astrographs, as well as a range of seismograph equipment (for detecting earthquakes). Its main activities are: * Reference systems and geodynamics; * Astrometry and dynamics of celestial bodies; * Astrophysics; * Solar physics. The asteroid 1276 Ucclia is named in honour of the city and the observatory and 16908 Groeselenberg is named for the hill the observatory is located on.

Sylvain Julien Victor Arend
Sylvain Julien Victor Arend (6 August 1902 – 18 February 1992) was a Belgian astronomer born in Robelmont, Luxembourg province, Belgium. His main interest was astrometry. Together with Georges Roland, he discovered the bright comet C/1956 R1 (Arend-Roland). He also discovered, or co-discovered, the periodic comets 49P/Arend-Rigaux and 50P/Arend, Nova Scuti 1952, and a number of asteroids, including notably the Amor asteroid 1916 Boreas and the Trojan asteroid 1583 Antilochus. He also discovered 1652 Hergé which is named after Hergé, the creator of ''The Adventures of Tintin''. The asteroid 1563 Noël is named after his son, Emanuel Arend. In 1948 Arend started together with sixteen other people the skeptic organisation Comité Para The Comité Para, in full Comité belge pour l'Analyse Critique des parasciences ("Belgian Committee for the Critical Analysis of Parasciences"), is a Francophone Belgian skeptical non-profit organisation.

1570 Brunonia
1570 Brunonia, provisional designation , is a stony asteroid of the Koronis family from the outer regions of the asteroid belt, approximately in diameter. It was discovered on 9 October 1948, by Belgian astronomer Sylvain Arend at the Royal Observatory of Belgium in Uccle. The S-type asteroid is likely elongated and has a longer-than-average rotation period of more than 48 hours. It was named for Brown University in Rhode Island, United States. Orbit and classification ''Brunonia'' is a core member of the Koronis family (), a very large outer asteroid family with nearly co-planar ecliptical orbits. It orbits the Sun in the outer main-belt at a distance of 2.7–3.0 AU once every 4 years and 10 months (1,754 days; semi-major axis of 2.85 AU). Its orbit has an eccentricity of 0.06 and an inclination of 2 ° with respect to the ecliptic.

Mayan Calendar
The Maya calendar is a system of calendars used in pre-Columbian Mesoamerica and in many modern communities in the Guatemalan highlands, Veracruz, Oaxaca and Chiapas, Mexico. The essentials of the Maya calendar are based upon a system which had been in common use throughout the region, dating back to at least the 5th century BC. It shares many aspects with calendars employed by other earlier Mesoamerican civilizations, such as the Zapotec and Olmec and contemporary or later ones such as the Mixtec and Aztec calendars. By the Maya mythological tradition, as documented in Colonial Yucatec accounts and reconstructed from Late Classic and Postclassic inscriptions, the deity Itzamna is frequently credited with bringing the knowledge of the calendrical system to the ancestral Maya, along with writing in general and other foundational aspects of Mayan culture. Overview The Maya calendar consists of several cycles or ''counts'' of different lengths. The 260-day count is known to sc ...

Supersonic Aircraft
A supersonic aircraft is an aircraft capable of supersonic flight, that is, flying faster than the speed of sound (Mach number 1). Supersonic speed, Supersonic aircraft were developed in the second half of the twentieth century. Supersonic aircraft have been used for research and military purposes, but only two supersonic aircraft, the Tupolev Tu-144 (first flown on December 31, 1968) and the Concorde (first flown on March 2, 1969), ever entered service Supersonic transport, for civil use as airliners. Fighter aircraft, Fighter jets are the most common example of supersonic aircraft. The aerodynamics of supersonic flight is called compressible flow because of the compression (physics), compression associated with the shock waves or "sonic boom" created by any object traveling faster than sound. Aircraft flying at speeds above Mach 5 are called Hypersonic flight, hypersonic aircraft. History The first aircraft to fly supersonic in level flight was the American Bell X-1 exper ...
