Ernest Marsden
Sir Ernest Marsden (19 February 1889 – 15 December 1970) was an English-New Zealand physicist. He is recognised internationally for his contributions to science while working under Ernest Rutherford, which led to the discovery of new theories on the structure of the atom. In Marsden's later work in New Zealand, he became a significant member of the scientific community, while maintaining close links to the United Kingdom. Education Born in Manchester, the son of Thomas Marsden and Phoebe Holden, Marsden lived in Rishton and attended Queen Elizabeth's Grammar School, Blackburn, where an inter-house trophy rewarding academic excellence ('The Marsden Merit Trophy') bears his name. In 1909, as a 20-year-old student at the University of Manchester, he met and began work under Ernest Rutherford.Rebecca Priestley, 'Ernest Marsden, 1889-1970', in Veronika Meduna and Rebecca Priestley (eds.), Atoms, Dinosaurs and DNA:68 Great New Zealand Scientists (Random House New Zealand: Auckla ...

Geiger–Marsden Experiment
The Rutherford scattering experiments were a landmark series of experiments by which scientists learned that every atom has a nucleus where all of its positive charge and most of its mass is concentrated. They deduced this after measuring how an alpha particle beam is scattered when it strikes a thin metal foil. The experiments were performed between 1906 and 1913 by Hans Geiger and Ernest Marsden under the direction of Ernest Rutherford at the Physical Laboratories of the University of Manchester. The physical phenomenon was explained by Rutherford in a classic 1911 paper that eventually led to the widespread use of scattering in particle physics to study subatomic matter. Rutherford scattering or Coulomb scattering is the elastic scattering of charged particles by the Coulomb interaction. The paper also initiated the development of the planetary Rutherford model of the atom and eventually the Bohr model. Rutherford scattering is now exploited by the materials science comm ...

Rishton
Rishton is a town in the Hyndburn district of Lancashire, England, about west of Clayton-le-Moors and north east of Blackburn. It was an urban district from about 1894 to 1974. The population at the census of 2011 was 6,625. History Its name means “village (or farmstead) where rushes grow”. In late 1776, a handloom weavers shop in Rishton, belonging to Thomas Duxbury may have been the first place that the cotton cloth calico was woven for sale in Great Britain. Rishton Colliery on the Burnley Coalfield was begun by P.W. Pickup Ltd in late November 1884 and mining continued until 1941. A tramroad from the pit connected to a coaling wharf on the canal. The National Coal Board used it as a pumping station from 1955 until 1970. Governance The two tiers of local government are Hyndburn Borough Council (a non-metropolitan district with borough status) and Lancashire County Council. Prior to the creation of Hyndburn district in 1974, Rishton had been an urban dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Evening Post (New Zealand)
''The Evening Post'' (8 February 1865 – 6 July 2002) was an afternoon metropolitan daily newspaper based in Wellington, New Zealand. It was founded in 1865 by Dublin-born printer, newspaper manager and leader-writer Henry Blundell, who brought his large family to New Zealand in 1863. With his partner from what proved to be a false-start at Havelock, David Curle, who left the partnership that July, Henry and his three sons printed with a hand-operated press and distributed Wellington's first daily newspaper, ''The Evening Post'', on 8 February 1865. Operating from 1894 as Blundell Bros Limited, his sons and their descendants continued the very successful business which dominated its circulation area. While ''The Evening Post'' was remarkable in not suffering the rapid circulation decline of evening newspapers elsewhere, it was decided in 1972 to merge ownership with that of the never-as-successful politically conservative morning paper, '' The Dominion'', which belonged t ...

King George V Silver Jubilee Medal
The King George V Silver Jubilee Medal is a commemorative medal, instituted to celebrate the 25th anniversary of the accession of King George V. Issue This medal was awarded as a personal souvenir by King George V to commemorate his Silver Jubilee. It was awarded to the Royal Family and selected officers of state, officials and servants of the Royal Household, ministers, government officials, mayors, public servants, local government officials, members of the navy, army, air force and police in Britain, her colonies and Dominions. For Coronation and Jubilee medals, the practice up until 1977 was that United Kingdom authorities decided on a total number to be produced, then allocated a proportion to each of the Commonwealth countries and Crown dependencies and possessions. The award of the medals was then at the discretion of the local government authority, who were free to decide who would be awarded a medal and why. A total of 85,234 medals were awarded, including *6,500 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rutherford Memorial Lecture
The Institute of Physics (IOP) is a UK-based not-for-profit learned society and professional body that works to advance physics education, research and application. It was founded in 1874 and has a worldwide membership of over 20,000. The IOP is the Physical Society for the UK and Ireland and supports physics in education, research and industry. In addition to this, the IOP provides services to its members including careers advice and professional development and grants the professional qualification of Chartered Physicist (CPhys), as well as Chartered Engineer (CEng) as a nominated body of the Engineering Council; it also holds its own separate Royal Charter. The IOP's publishing company, IOP Publishing, publishes 85 academic titles.

It is New Zealand's List of cities in New Zealand, sixth most populous city, with a population of . The total area administered by the council is around the lower half of the Hutt Valley and along the eastern shores of Wellington Harbour, of which is urban. It is separated from the city of Wellington by the harbour, and from Upper Hutt by the Taita Gorge. Lower Hutt is unique among New Zealand cities, as the name of the council does not match the name of the city it governs. Special legislation has since 1991 given the council the name "Hutt City Council", while the name of the place itself remains "Lower Hutt City". This name has led to confusion, as Upper Hutt is administered by a separate city council, the Upper Hutt City C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Radar
Radar is a system that uses radio waves to determine the distance ('' ranging''), direction ( azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain. The term ''RADAR'' was coined in 1940 by the United States Navy as an acronym for "radio detection and ranging". The term ''radar'' has since entered English and other languages as an anacronym, a common noun, losing all capitalization. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwave domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
