George Laurence
George Craig Laurence (21 January 1905 – 6 November 1987) was a Canadian nuclear physicist. He was educated at Dalhousie University, and at Cambridge University under Ernest Rutherford. He was appointed as Radium and X-ray physicist to the Canadian National Research Council in 1930. In 1939-40 he attempted to build a graphite-uranium reactor in Ottawa, anticipating Enrico Fermi's work by several months. In 1942 he joined the Anglo-French nuclear research team at the Montreal Laboratory, where he was responsible for recruiting Canadian scientists. The laboratory later transferred to the Chalk River, and built the ZEEP Reactor, the first outside the U.S.A. In 1946-47 he was in the Canadian delegation to the United Nations Atomic Energy Commission. He then returned to Montreal Laboratory and continued to carry out his research from 1950 to 1961. He was then at the Chalk River Laboratory, and was President of the Atomic Energy Control Board from 1961 to 1970. Laurence Court, a ...

Charlottetown
Charlottetown is the capital and largest city of the Canadian province of Prince Edward Island, and the county seat of Queens County. Named after Queen Charlotte, Charlottetown was an unincorporated town until it was incorporated as a city in 1855. It was the site of the famous Charlottetown Conference in 1864, the first gathering of Canadian and Maritime statesmen to discuss the proposed Maritime Union. This conference led, instead, to the union of British North American colonies in 1867, which was the beginning of the Canadian confederation. PEI, however, did not join Confederation until 1873. From this, the city adopted as its motto ''Cunabula Foederis'', "Birthplace of Confederation". The population of Charlottetown is estimated to be 40,500 (2022); this forms the centre of a census agglomeration of 83,063 (2021), which is roughly half of the province's population (160,302). History Early history (1720–1900) The first European settlers in the area were French; perso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Physicist
Nuclear physics is the field of physics that studies atomic nuclei and their constituents and interactions, in addition to the study of other forms of nuclear matter. Nuclear physics should not be confused with atomic physics, which studies the atom as a whole, including its electrons. Discoveries in nuclear physics have led to applications in many fields. This includes nuclear power, nuclear weapons, nuclear medicine and magnetic resonance imaging, industrial and agricultural isotopes, ion implantation in materials engineering, and radiocarbon dating in geology and archaeology. Such applications are studied in the field of nuclear engineering. Particle physics evolved out of nuclear physics and the two fields are typically taught in close association. Nuclear astrophysics, the application of nuclear physics to astrophysics, is crucial in explaining the inner workings of stars and the origin of the chemical elements.

Manhattan Project People
Manhattan (), known regionally as the City, is the most densely populated and geographically smallest of the five boroughs of New York City. The borough is also coextensive with New York County, one of the original counties of the U.S. state of New York. Located near the southern tip of New York State, Manhattan is based in the Eastern Time Zone and constitutes both the geographical and demographic center of the Northeast megalopolis and the urban core of the New York metropolitan area, the largest metropolitan area in the world by urban landmass. Over 58 million people live within 250 miles of Manhattan, which serves as New York City’s economic and administrative center, cultural identifier, and the city’s historical birthplace. Manhattan has been described as the cultural, financial, media, and entertainment capital of the world, is considered a safe haven for global real estate investors, and hosts the United Nations headquarters. New York City is the headquarters of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canadian Nuclear Physicists
Canadians (french: Canadiens) are people identified with the country of Canada. This connection may be residential, legal, historical or cultural. For most Canadians, many (or all) of these connections exist and are collectively the source of their being ''Canadian''. Canada is a multilingual and multicultural society home to people of groups of many different ethnic, religious, and national origins, with the majority of the population made up of Old World immigrants and their descendants. Following the initial period of French and then the much larger British colonization, different waves (or peaks) of immigration and settlement of non-indigenous peoples took place over the course of nearly two centuries and continue today. Elements of Indigenous, French, British, and more recent immigrant customs, languages, and religions have combined to form the culture of Canada, and thus a Canadian identity. Canada has also been strongly influenced by its linguistic, geographic, and e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Library And Archives Canada
Library and Archives Canada (LAC; french: Bibliothèque et Archives Canada) is the federal institution, tasked with acquiring, preserving, and providing accessibility to the documentary heritage of Canada. The national archive and library is the fifth largest library in the world. The LAC reports to the Parliament of Canada through the Minister of Canadian Heritage. The LAC traces its origins to the Dominion Archives, formed in 1872, and the National Library of Canada, formed in 1953. The former was later renamed as the Public Archives of Canada in 1912, and the National Archives of Canada in 1987. In 2004, the National Archives of Canada and the National Library of Canada were merged to form Library and Archives Canada. History Predecessors The Dominion Archives was founded in 1872 as a division within the Department of Agriculture tasked with acquiring and transcribing documents related to Canadian history. In 1912, the division was transformed into an autonomous organiz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fonds
In archival science, a fonds is a group of documents that share the same origin and that have occurred naturally as an outgrowth of the daily workings of an agency, individual, or organization. An example of a fonds could be the writings of a poet that were never published or the records of an institution during a specific period. Fonds are a part of a hierarchical level of description system in an archive that begins with fonds at the top, and the subsequent levels become more descriptive and narrower as one goes down the hierarchy. The level of description goes from fonds to series to file and then an item level. However, between the fonds and series level there is sometimes a sub-fonds or sous-fonds level and between the series to file level there is sometimes a sub-series level that helps narrow down the hierarchy. Historical origins In the archival science field, it is widely agreed upon that the term ''fonds'' originated in French archival practice shortly after the Frenc ...

ZEEP
The ZEEP (Zero Energy Experimental Pile) reactor was a nuclear reactor built at the Chalk River Laboratories near Chalk River, Ontario, Canada (which superseded the Montreal Laboratory for nuclear research in Canada). ZEEP first went critical at 15:45 on September 5, 1945. ZEEP was the first operational nuclear reactor outside the United States. The reactor was designed by Canadian, British and French scientists as a part of an effort to produce plutonium for nuclear weapons during World War II."Canada's Historical Role in Developing Nuclear Weapons" Canadian Nuclear Safety Commission.

Enrico Fermi
Enrico Fermi (; 29 September 1901 – 28 November 1954) was an Italian (later naturalized American) physicist and the creator of the world's first nuclear reactor, the Chicago Pile-1. He has been called the "architect of the nuclear age" and the "architect of the atomic bomb". He was one of very few physicists to excel in both theoretical physics and experimental physics. Fermi was awarded the 1938 Nobel Prize in Physics for his work on induced radioactivity by neutron bombardment and for the discovery of transuranium elements. With his colleagues, Fermi filed several patents related to the use of nuclear power, all of which were taken over by the US government. He made significant contributions to the development of statistical mechanics, Quantum mechanics, quantum theory, and nuclear physics, nuclear and particle physics. Fermi's first major contribution involved the field of statistical mechanics. After Wolfgang Pauli formulated his Pauli exclusion principle, exclusion pri ...
