Klára Dán Von Neumann
Klára Dán von Neumann (born Klára Dán; 18 August 1911 – 10 November 1963) was a Hungarian-American mathematician, self-taught engineer and computer scientist, noted as one of the first computer programmers. She was the first woman to execute modern-style code on a computer. Klára made significant contributions to the world of programming, including work on the Monte Carlo method, ENIAC, and MANIAC I. She was introduced to a lot of her work through her husband, John von Neumann. Early life Klára Dán, known as Klárí to her friends and family, was born in Budapest, Hungary on August 18, 1911, to Károly Dán and Kamilla Stadler, a wealthy Jewish couple. Her father had previously served in the Austro-Hungarian Army as an officer during World War I, and the family moved to Vienna to escape Béla Kun's Hungarian Soviet Republic. Once the regime was overthrown, the family moved back to Budapest. Her family was wealthy, and often held parties where Dán would meet many di ...

Alfred Eisenstaedt
Alfred Eisenstaedt (December 6, 1898 – August 23, 1995) was a German-born American photographer and photojournalist. He began his career in Germany prior to World War II but achieved prominence as a staff photographer for ''Life'' magazine after moving to the U.S. ''Life'' featured more than 90 of his pictures on its covers, and more than 2,500 of his photo stories were published. Among his most famous cover photographs was ''V-J Day in Times Square'', taken during the V-J Day celebration in New York City, showing an American sailor kissing a nurse in a "dancelike dip" which "summed up the euphoria many Americans felt as the war came to a close", in the words of his obituary. He was "renowned for his ability to capture memorable images of important people in the news" and for his candid photographs taken with a small 35mm Leica camera, typically with natural lighting. Early life Eisenstaedt was born in Dirschau (Tczew) in West Prussia, Imperial Germany in 1898. His family ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monte Carlo Method
Monte Carlo methods, or Monte Carlo experiments, are a broad class of computational algorithms that rely on repeated random sampling to obtain numerical results. The underlying concept is to use randomness to solve problems that might be deterministic in principle. They are often used in physical and mathematical problems and are most useful when it is difficult or impossible to use other approaches. Monte Carlo methods are mainly used in three problem classes: optimization, numerical integration, and generating draws from a probability distribution. In physics-related problems, Monte Carlo methods are useful for simulating systems with many coupled degrees of freedom, such as fluids, disordered materials, strongly coupled solids, and cellular structures (see cellular Potts model, interacting particle systems, McKean–Vlasov processes, kinetic models of gases). Other examples include modeling phenomena with significant uncertainty in inputs such as the calculation of ris ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adele Goldstine
Adele Goldstine (; December 21, 1920 – November 1964) was an American mathematician and computer programmer. She wrote the manual for the first electronic digital computer, ENIAC. Through her work programming the computer, she was also an instrumental player in converting the ENIAC from a computer that needed to be reprogrammed each time it was used to one that was able to perform a set of fifty stored instructions.Jones, J. Sydney. "Adele Katz Goldstine." In ''Notable Women Scientists.'' Gale: 1999, pp. 212–13 Early life and education Goldstine was born in New York City on December 21, 1920, to Yiddish-speaking Jewish parents.

Smithsonian Institution
The Smithsonian Institution ( ), or simply the Smithsonian, is a group of museums and education and research centers, the largest such complex in the world, created by the U.S. government "for the increase and diffusion of knowledge". Founded on August 10, 1846, it operates as a trust instrumentality and is not formally a part of any of the three branches of the federal government. The institution is named after its founding donor, British scientist James Smithson. It was originally organized as the United States National Museum, but that name ceased to exist administratively in 1967. Called "the nation's attic" for its eclectic holdings of 154 million items, the institution's 19 museums, 21 libraries, nine research centers, and zoo include historical and architectural landmarks, mostly located in the District of Columbia. Additional facilities are located in Maryland, New York, and Virginia. More than 200 institutions and museums in 45 states,States without Smithsonian ...

Smithsonian (magazine)
''Smithsonian'' is the official journal published by the Smithsonian Institution in Washington, D.C. The first issue was published in 1970. History The history of ''Smithsonian'' began when Edward K. Thompson, the retired editor of ''Life (magazine), Life'' magazine, was asked by the then-Secretary of the Smithsonian, S. Dillon Ripley, to produce a magazine "about things in which the Smithsonian [Institution] is interested, might be interested or ought to be interested." Thompson would later recall that his philosophy for the new magazine was that it "would stir curiosity in already receptive minds. It would deal with history as it is relevant to the present. It would present art, since true art is never dated, in the richest possible reproduction. It would peer into the future via coverage of social progress and of science and technology. Technical matters would be digested and made intelligible by skilled writers who would stimulate readers to reach upward while not turning the ...

Office Of Population Research
The Office of Population Research (OPR) at Princeton University is the oldest population research center in the United States. Founded in 1936, the OPR is a leading demographic research and training center. Recent research activity has primarily focused on healthcare, social demography, urbanization, and migration. The OPR's research has been cited in numerous articles by the ''New York Times'' and the ''Wall Street Journal''. History Major General, heir, and eugenicist Frederick H. Osborn, a graduate of Princeton University, laid the foundation for the Office of Population Research in 1936. The founding director of OPR was Frank W. Notestein, who was a demographer at the Milbank Memorial Fund, a leading peer-reviewed healthcare journal. While at the OPR, he was also the director of the Population Division of the United Nations between 1946 and 1948. He left in 1959 to lead the Population Council, an international, nonprofit, non-governmental organization. He was succeeded as OP ...

Manhattan Project
The Manhattan Project was a research and development undertaking during World War II that produced the first nuclear weapons. It was led by the United States with the support of the United Kingdom and Canada. From 1942 to 1946, the project was under the direction of Major General Leslie Groves of the United States Army Corps of Engineers, U.S. Army Corps of Engineers. Nuclear physicist Robert Oppenheimer was the director of the Los Alamos Laboratory that designed the actual bombs. The Army component of the project was designated the Manhattan District as its first headquarters were in Manhattan; the placename gradually superseded the official codename, Development of Substitute Materials, for the entire project. Along the way, the project absorbed its earlier British counterpart, Tube Alloys. The Manhattan Project began modestly in 1939, but grew to employ more than 130,000 people and cost nearly US$2 billion (equivalent to about $ billion in ). Over 90 percent of th ...

Attack On Pearl Harbor
The attack on Pearl HarborAlso known as the Battle of Pearl Harbor was a surprise military strike by the Imperial Japanese Navy Air Service upon the United States against the naval base at Pearl Harbor in Honolulu, Territory of Hawaii, just before 8:00a.m. (local time) on Sunday, December 7, 1941. The United States was a neutral country at the time; the attack led to its formal entry into World War II the next day. The Japanese military leadership referred to the attack as the Hawaii Operation and Operation AI, and as Operation Z during its planning. Japan intended the attack as a preventive action. Its aim was to prevent the United States Pacific Fleet from interfering with its planned military actions in Southeast Asia against overseas territories of the United Kingdom, the Netherlands, and those of the United States. Over the course of seven hours there were coordinated Japanese attacks on the US-held Philippines, Guam, and Wake Island and on the British Empire ...

Hungarian Soviet Republic
The Socialist Federative Republic of Councils in Hungary ( hu, Magyarországi Szocialista Szövetséges Tanácsköztársaság) (due to an early mistranslation, it became widely known as the Hungarian Soviet Republic in English-language sources ( hu, Magyar Szovjet-köztársaság)), literally the Republic of Councils in Hungary ( hu, Magyarországi Tanácsköztársaság) was a short-lived Communist state that existed from 21 March 1919 to 1 August 1919 (133 days), succeeding the First Hungarian Republic. The Hungarian Soviet Republic was a small communist rump state. When the Republic of Councils in Hungary was established, it controlled only approximately 23% of the Hungary's historic territory. The head of government was Sándor Garbai, but the influence of the foreign minister Béla Kun from the Hungarian Communist Party was much stronger. Unable to reach an agreement with the Triple Entente, which maintained an economic blockade in Hungary, tormented by neighboring countries fo ...

Béla Kun
Béla Kun (born Béla Kohn; 20 February 1886 – 29 August 1938) was a Hungarian communist revolutionary and politician who governed the Hungarian Soviet Republic in 1919. After attending Franz Joseph University at Kolozsvár (today Cluj-Napoca, Romania), Kun worked as a journalist before the First World War. He served in the Austro-Hungarian Army and was captured by the Imperial Russian Army in 1916, after which he was sent to a prisoner-of-war camp in the Urals. Kun embraced communist ideas during his time in Russia, and in 1918 he co-founded a Hungarian arm of the Russian Communist Party in Moscow. He befriended Vladimir Lenin and fought for the Bolsheviks in the Russian Civil War. In November 1918, Kun returned to Hungary with Soviet support and set up the Party of Communists in Hungary. Adopting Lenin's tactics, he agitated against the government of Mihály Károlyi and achieved great popularity despite being imprisoned. After his release in March 1919, Kun led a success ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Austro-Hungarian Army
The Austro-Hungarian Army (, literally "Ground Forces of the Austro-Hungarians"; , literally "Imperial and Royal Army") was the ground force of the Austro-Hungarian Dual Monarchy from 1867 to 1918. It was composed of three parts: the joint army (, "Common Army", recruited from all parts of the country), the Imperial Austrian Landwehr (recruited from Cisleithania), and the Royal Hungarian Honvéd (recruited from Transleithania). In the wake of fighting between the Austrian Empire and the Hungarian Kingdom and the two decades of uneasy co-existence following, Hungarian soldiers served either in mixed units or were stationed away from Hungarian areas. With the Austro-Hungarian Compromise of 1867 the new tripartite army was brought into being. It existed until the disestablishment of the Austro-Hungarian Empire following World War I in 1918. The joint "Imperial and Royal Army" ( or ''k.u.k.'') units were generally poorly trained and had very limited access to new equipment bec ...
