James Stanley Hey
James Stanley Hey (3 May 1909 – 27 February 2000) was an English physicist and radio astronomer. With the targeted application of radar technology for astronomical research, he laid the basis for the development of radio astronomy. While working in Richmond Park during the Second World War, He discovered that the Sun radiates radio waves and localised for the first time an extragalactic radio source in the constellation Cygnus. Early life and education He was born in 1909 in Nelson, Lancashire, the third son of a cotton manufacturer, which was the main industry in Lancashire. Hey studied physics at the University of Manchester, graduating in 1930, and obtained his master's degree in X-ray crystallography the next year as a student of Lawrence Bragg. Career After graduating, Hey became a teacher, and taught physics at Burnley Grammar School for some years. In 1940 Hey joined the Air Defence Research and Development Establishment's (ADRDE) Operational Research Group, late ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crystallography
Crystallography is the experimental science of determining the arrangement of atoms in crystalline solids. Crystallography is a fundamental subject in the fields of materials science and solid-state physics (condensed matter physics). The word "crystallography" is derived from the Greek word κρύσταλλος (''krystallos'') "clear ice, rock-crystal", with its meaning extending to all solids with some degree of transparency, and γράφειν (''graphein'') "to write". In July 2012, the United Nations recognised the importance of the science of crystallography by proclaiming that 2014 would be the International Year of Crystallography. denote a direction vector (in real space). * Coordinates in ''angle brackets'' or ''chevrons'' such as <100> denote a ''family'' of directions which are related by symmetry operations.

Richmond Local History Society
Richmond is a town in south-west London,The London Government Act 1963 (c.33) (as amended) categorises the London Borough of Richmond upon Thames as an Outer London borough. Although it is on both sides of the River Thames, the Boundary Commission for England defines it as being in South London or the South Thames sub-region, pairing it with Kingston upon Thames for the purposes of devising constituencies. However, for the purposes of the London Plan, Richmond now lies within the West London region. west-southwest of Charing Cross. It is on a meander of the River Thames, with many parks and open spaces, including Richmond Park, and many protected conservation areas, which include much of Richmond Hill. A specific Act of Parliament protects the scenic view of the River Thames from Richmond. Richmond was founded following Henry VII's building of Richmond Palace in the 16th century, from which the town derives its name. (The palace itself was named after Henry's earldom of ...

The Antiquarian Astronomer
The Society for the History of Astronomy is an organisation based in the United Kingdom that promotes research into the history of astronomy. It publishes a research journal called ''The Antiquarian Astronomer'' and a regular ''Bulletin''. The society The Society for the History of Astronomy was founded in 2002 to promote the study of the history of astronomy by hosting talks by members and publishing new research into the field. One main objective was to encourage research into past astronomers who have previously been neglected within the history of science. Some of its members are professional historians of science but most are amateur historians. The honorary president is Dr Allan Chapman of Wadham College, Oxford. The honorary vice-presidents are Emily Winterburn (who was chair at the time of foundation) and Prof. Mike Edmunds.

Grote Reber
Grote Reber (December 22, 1911 – December 20, 2002) was an American pioneer of radio astronomy, which combined his interests in amateur radio and amateur astronomy. He was instrumental in investigating and extending Karl Jansky's pioneering work, and conducted the first sky survey in the radio frequencies. His 1937 radio antenna was the second ever to be used for astronomical purposes and the first parabolic reflecting antenna to be used as a radio telescope. For nearly a decade he was the world's only radio astronomer.Wayne Orchiston, The New Astronomy: Opening the Electromagnetic Window and Expanding our View of Planet Earth: A Meeting to Honor Woody Sullivan on his 60th Birthday, Springer Science & Business Media – 2006, p. 63Robert Bless (1996), ''Discovering the Cosmos'', University Science Books, p. 215 Life Reber was born and raised in Wheaton, Illinois, a suburb of Chicago, and graduated from Armour Institute of Technology (now Illinois Institute of Technology) in 19 ...

Karl Guthe Jansky
Karl Guthe Jansky (October 22, 1905 – February 14, 1950) was an American physicist and radio engineer who in April 1933 first announced his discovery of radio waves emanating from the Milky Way in the constellation Sagittarius. He is considered one of the founding figures of radio astronomy. Early life Karl Guthe Jansky was born 1905 in what was then the Territory of Oklahoma where his father, Cyril M. Jansky, was Dean of the College of Engineering at the University of Oklahoma at Norman. Cyril M. Jansky, born in Wisconsin of Czech immigrants, had started teaching at the age of sixteen. He was a teacher throughout his active life, retiring as Professor of Electrical Engineering at the University of Wisconsin. He was an engineer with a strong interest in physics, a trait passed on to his sons.

Meteor
A meteoroid () is a small rocky or metallic body in outer space. Meteoroids are defined as objects significantly smaller than asteroids, ranging in size from grains to objects up to a meter wide. Objects smaller than this are classified as micrometeoroids or space dust. Most are fragments from comets or asteroids, whereas others are collision impact debris ejected from bodies such as the Moon or Mars. When a meteoroid, comet, or asteroid enters Earth's atmosphere at a speed typically in excess of , aerodynamic heating of that object produces a streak of light, both from the glowing object and the trail of glowing particles that it leaves in its wake. This phenomenon is called a meteor or "shooting star". Meteors typically become visible when they are about 100 km above sea level. A series of many meteors appearing seconds or minutes apart and appearing to originate from the same fixed point in the sky is called a meteor shower. A meteorite is the remains of a meteoroid th ...

V-2 Rocket
The V-2 (german: Vergeltungswaffe 2, lit=Retaliation Weapon 2), with the technical name ''Aggregat 4'' (A-4), was the world’s first long-range guided ballistic missile. The missile, powered by a liquid-propellant rocket engine, was developed during the Second World War in Nazi Germany as a "vengeance weapon" and assigned to attack Allied cities as retaliation for the Allied bombings of German cities. The rocket also became the first artificial object to travel into space by crossing the Kármán line (edge of space) with the vertical launch of MW 18014 on 20 June 1944. Research into military use of long-range rockets began when the graduate studies of Wernher von Braun attracted the attention of the Wehrmacht. A series of prototypes culminated in the A-4, which went to war as the . Beginning in September 1944, over 3,000 were launched by the Wehrmacht against Allied targets, first London and later Antwerp and Liège. According to a 2011 BBC documentary, the attacks from r ...

George Clark Southworth
George Clark Southworth (August 24, 1890 – July 6, 1972), who published as G. C. Southworth, was a prominent American radio engineer best known for his role in the development of waveguides in the early 1930s. Biography Southworth was born in Little Cooley, Pennsylvania, graduated in 1914 with a physics degree from Grove City College, and studied one year at Columbia University. In June 1917 he joined the National Bureau of Standards, then in 1918 moved to Yale University to teach in a Signal Corps school. He remained at Yale to complete a doctorate in 1923 on the measurement of the dielectric constant of water at frequencies above 15 MHz. Southworth left Yale for a position with the American Telephone and Telegraph Company, where he first helped edit the Bell System Technical Journal, but then switched to researching shortwave radio propagation. In 1931 he began to study wave propagation in dielectric rods, by early 1932 observed wave propagation in a water-filled coppe ...

Royal Observatory, Greenwich
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 Greenw ...

Channel Dash
The Channel Dash (german: Unternehmen Zerberus, Operation Cerberus) was a German naval operation during the Second World War. (Cerberus), a three-headed dog of Greek mythology who guards the gate to Hades. A (German Navy) squadron comprising the two s, the heavy cruiser and their escorts was evacuated from Brest in Brittany to German ports. ''Scharnhorst'' and ''Gneisenau'' had arrived in Brest on 22 March 1941 after the success of Operation Berlin in the Atlantic. More raids were planned and the ships were refitted at Brest. The ships were a threat to Allied trans-Atlantic convoys and RAF Bomber Command attacked them from 30 March 1941. ''Gneisenau'' was hit on 6 April 1941 and ''Scharnhorst'' on 24 July 1941, after dispersal to La Pallice. In late 1941, Adolf Hitler ordered the (OKM; German Navy High Command) to plan an operation to return the ships to German bases against a British invasion of Norway. The short route up the English Channel was preferred to a detour around ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
