124-408: The GSL project was initiated in 1996 by physicists Mark Galassi and James Theiler of Los Alamos National Laboratory . They aimed at writing a modern replacement for widely used but somewhat outdated Fortran libraries such as Netlib . They carried out the overall design and wrote early modules; with that ready they recruited other scientists to contribute. The "overall development of the library and

248-451: A Department of Energy investigation into the laboratory. The investigation found that the "missing plutonium" was a result of miscalculation by LANL's statisticians and did not actually exist; but the investigation did lead to heavy criticism of the laboratory by the DOE for security flaws and weaknesses that the DOE claimed to have found. LANL is northern New Mexico's largest institution and

372-804: A German rebuilding effort set forth by western European countries in 1948, the US, Britain and France spearheaded the establishment of the Federal Republic of Germany from the three Western zones of occupation in April 1949. The Soviet Union proclaimed its zone of occupation in Germany the German Democratic Republic that October. Media in the Eastern Bloc was an organ of the state , completely reliant on and subservient to

496-551: A drum containing nuclear waste was ruptured due to a ' deflagration ' according to an inspector general report of the Dept. of Energy, which due to lab mistakes, also occurred in 2014 at the Carlsbad plant with significant disruptions and costs across the industry. In 2009, 69 computers which did not contain classified information were lost. The same year also saw a scare in which 1 kg (2.2 lb) of missing plutonium prompted

620-409: A file server, a batch server, a printer and graphics output server and numerous other general purpose and specialized systems. IBM Roadrunner , which was part of this network, was the first supercomputer to hit petaflop speeds. Until 1999, The Los Alamos National Laboratory hosted the arXiv e-print archive. The arXiv is currently operated and funded by Cornell University . The coreboot project

744-646: A general term, in his essay "You and the Atomic Bomb", published 19 October 1945 in the British newspaper Tribune . Contemplating a world living in the shadow of the threat of nuclear warfare , Orwell looked at James Burnham 's predictions of a polarized world, writing: Looking at the world as a whole, the drift for many decades has been not towards anarchy but towards the reimposition of slavery... James Burnham's theory has been much discussed, but few people have yet considered its ideological implications—that is,

868-522: A major propaganda effort began in 1949 was Radio Free Europe/Radio Liberty , dedicated to bringing about the peaceful demise of the communist system in the Eastern Bloc. Radio Free Europe attempted to achieve these goals by serving as a surrogate home radio station, an alternative to the controlled and party-dominated domestic press in the Soviet Bloc. Radio Free Europe was a product of some of

992-642: A neutral Germany to prevent West Germany's incorporation into NATO, but his attempts were cut short after he was executed several months later during a Soviet power struggle. The events led to the establishment of the Bundeswehr , the West German military, in 1955. In 1949, CCP Chairman Mao Zedong 's People's Liberation Army defeated Chiang Kai-shek 's United States-backed Kuomintang (KMT) Nationalist Government in China. The KMT-controlled territory

1116-675: A new war". On 6 September 1946, James F. Byrnes delivered a speech in Germany repudiating the Morgenthau Plan (a proposal to partition and de-industrialize post-war Germany) and warning the Soviets that the US intended to maintain a military presence in Europe indefinitely. As Byrnes stated a month later, "The nub of our program was to win the German people ... it was a battle between us and Russia over minds ..." In December,

1488-710: A plan envisioning an economically self-sufficient Germany, including a detailed accounting of the industrial plants, goods and infrastructure already taken by the Soviets. In June 1947, in accordance with the Truman Doctrine , the United States enacted the Marshall Plan , a pledge of economic assistance for all European countries willing to participate, including the Soviet Union. Under the plan, which President Harry S. Truman signed on 3 April 1948,

1612-722: A second design lab under the direction of the University of California, Berkeley , which became the Lawrence Livermore National Laboratory (LLNL). The two labs competed on a wide variety of bomb designs, but with the end of the Cold War , have focused increasingly on civilian missions. Today, Los Alamos conducts multidisciplinary research in fields such as national security , space exploration , nuclear fusion , renewable energy , medicine , nanotechnology , and supercomputing . While owned by

1736-629: A secret 1950 document, the National Security Council proposed reinforcing pro-Western alliance systems and quadrupling spending on defense. Truman, under the influence of advisor Paul Nitze , saw containment as implying complete rollback of Soviet influence in all its forms. United States officials moved to expand this version of containment into Asia , Africa , and Latin America , in order to counter revolutionary nationalist movements, often led by communist parties financed by

1860-444: A secure area within the laboratory, but were later found behind a photocopier. Los Alamos National Laboratory's mission is to "solve national security challenges through simultaneous excellence". The laboratory's strategic plan reflects U.S. priorities spanning nuclear security, intelligence, defense, emergency response, nonproliferation, counterterrorism, energy security , emerging threats, and environmental management. This strategy

1984-589: A short distance northwest of Santa Fe, New Mexico , in the American southwest . Best known for its central role in helping develop the first atomic bomb , LANL is one of the world's largest and most advanced scientific institutions. Los Alamos was established in 1943 as Project Y , a top-secret site for designing nuclear weapons under the Manhattan Project during World War II . Chosen for its remote yet relatively accessible location, it served as

2108-480: A source of intelligence. During the late 1970s and 1980s, the KGB perfected its use of espionage to sway and distort diplomacy. Active measures were "clandestine operations designed to further Soviet foreign policy goals," consisting of disinformation, forgeries, leaks to foreign media, and the channeling of aid to militant groups. Retired KGB Major General Oleg Kalugin , former head of Foreign Counter Intelligence for

2232-600: A third accident occurred during an annual physical inventory in December 1958. Several buildings associated with the Manhattan Project at Los Alamos were declared a National Historic Landmark in 1965. At the end of the Cold War , both labs went through a process of intense scientific diversification in their research programs to adapt to the changing political conditions that no longer required as much research towards developing new nuclear weapons and has led

2356-555: A time. In 1979, the toppling of pro-US governments in Iran and Nicaragua and a Soviet invasion of Afghanistan again raised fears of war. In the 1980s, the US provided support for anti-communist forces in Africa, Asia, and Latin America, and the leadership of the USSR changed with the rise of Mikhail Gorbachev , who expanded political freedoms in his country and the Eastern Bloc. This led to

2480-542: A unified and neutral Germany was undesirable, with Walter Bedell Smith telling General Eisenhower "in spite of our announced position, we really do not want nor intend to accept German unification on any terms that the Russians might agree to, even though they seem to meet most of our requirements." Shortly thereafter, Stalin instituted the Berlin Blockade (June 1948 – May 1949), one of the first major crises of

2604-911: Is aligned with priorities set by the Department of Energy (DOE), the National Nuclear Security Administration (NNSA), and national strategy guidance documents, such as the Nuclear Posture Review , the National Security Strategy , and the Blueprint for a Secure Energy Future.

They do offer access to matrix and vector classes without having to use GSL's interface to malloc and free functions. Some also offer support for also creating workspaces that behave like Smart pointer classes. Finally, there is (limited, as of April 2020) support for allowing the user to create classes to represent

2976-466: The Army-Navy "E" Award for Excellence in production on October 16, 1945. After the war, Oppenheimer retired from the directorship, and it was taken over by Norris Bradbury , whose initial mission was to make the previously hand-assembled atomic bombs "G.I. proof" so that they could be mass-produced and used without the assistance of highly trained scientists. Other founding members of Los Alamos left

3100-513: The Baltic to Trieste in the Adriatic ". A week later, on 13 March, Stalin responded vigorously to the speech, saying Churchill could be compared to Adolf Hitler insofar as he advocated the racial superiority of English-speaking nations so that they could satisfy their hunger for world domination, and that such a declaration was "a call for war on the USSR." The Soviet leader also dismissed

3224-859: The Berlin Wall to prevent the citizens of East Berlin from fleeing to West Berlin , at the time part of United States-allied West Germany . Major crises of this phase included the Berlin Blockade of 1948–1949, the Chinese Communist Revolution of 1945–1949, the Korean War of 1950–1953, the Hungarian Revolution of 1956 and the Suez Crisis of that same year, the Berlin Crisis of 1961 ,

3348-758: The Cuban Missile Crisis began after deployments of U.S. missiles in Europe and Soviet missiles in Cuba; it is widely considered the closest the Cold War came to escalating into full-scale nuclear war . Another major proxy conflict was the Vietnam War of 1955 to 1975; the Soviets solidified their domination of Eastern Europe with operations such as the Warsaw Pact invasion of Czechoslovakia in 1968. Both powers used economic aid in an attempt to win

3472-719: The Cuban Missile Crisis of 1962, and the Vietnam War of 1964–1975. Both superpowers competed for influence in Latin America and the Middle East , and the decolonising states of Africa , Asia , and Oceania . Following the Cuban Missile Crisis, this phase of the Cold War saw the Sino-Soviet split . Between China and the Soviet Union's complicated relations within the Communist sphere, leading to

The laboratory's multidisciplinary scientific capabilities and activities are organized into six Capability Pillars: Los Alamos operates three main user facilities: As of 2017, the Los Alamos National Laboratory is using data and algorithms to possibly protect public health by tracking

3720-847: The Eastern Bloc . Cominform faced an embarrassing setback the following June, when the Tito–Stalin split obliged its members to expel Yugoslavia, which remained communist but adopted a non-aligned position and began accepting financial aid from the US. Besides Berlin, the status of the city of Trieste was at issue. Until the break between Tito and Stalin, the Western powers and the Eastern bloc faced each other uncompromisingly. In addition to capitalism and communism, Italians and Slovenes, monarchists and republicans as well as war winners and losers often faced each other irreconcilably. The neutral buffer state Free Territory of Trieste , founded in 1947 with

3844-756: The Human Immunodeficiency Virus were being tested by lab scientist Bette Korber and her team. "These vaccines might finally deal a lethal blow to the AIDS virus ", says Chang-Shung Tung, leader of the Lab's Theoretical Biology and Biophysics group. The laboratory has attracted negative publicity from a number of events. In 1999, Los Alamos scientist Wen Ho Lee was accused of 59 counts of mishandling classified information by downloading nuclear secrets—"weapons codes" used for computer simulations of nuclear weapons tests—to data tapes and removing them from

3968-511: The KGB and involved in its intelligence operations, adhered to Moscow's line, although dissent began to appear after 1956. Other critiques of the consensus policy came from anti-Vietnam War activists , the Campaign for Nuclear Disarmament , and the anti-nuclear movement . In early 1947, France, Britain and the United States unsuccessfully attempted to reach an agreement with the Soviet Union for

4092-518: The Kingdom of Greece in its civil war against Communist-led insurgents. In the same month, Stalin conducted the rigged 1947 Polish legislative election which constituted an open breach of the Yalta Agreement . The US government responded to this announcement by adopting a policy of containment , with the goal of stopping the spread of communism . Truman delivered a speech calling for

Los Alamos National Laboratory is a partner in the Joint Genome Institute (JGI) located in Walnut Creek, California . JGI was founded in 1997 to unite

4340-569: The Sino-Soviet border conflict , while France, a Western Bloc state, began to demand greater autonomy of action. The Warsaw Pact invasion of Czechoslovakia occurred to suppress the Prague Spring of 1968, while the United States experienced internal turmoil from the civil rights movement and opposition to United States involvement in the Vietnam War . In the 1960s–1970s, an international peace movement took root among citizens around

4464-746: The Soviet boycott of the Allied Control Council and its incapacitation, an event marking the beginning of the full-blown Cold War and the end of its prelude, as well as ending any hopes at the time for a single German government and leading to formation in 1949 of the Federal Republic of Germany and German Democratic Republic . The twin policies of the Truman Doctrine and the Marshall Plan led to billions in economic and military aid for Western Europe, Greece, and Turkey. With

4588-608: The Space Race . The US and USSR were both part of the Allies of World War II , the military coalition which had defeated Nazi Germany and Imperial Japan in 1945. After the war, the USSR installed satellite governments in the territories of Eastern and Central Europe it had occupied, and promoted the spread of communism to North Korea in 1948 and created an alliance with the People's Republic of China in 1949. The US declared

4712-568: The Truman Doctrine of " containment " in 1947, launched the Marshall Plan in 1948 to assist Western Europe's economic recovery, and founded the NATO military alliance in 1949 (which was matched by the Soviet-led Warsaw Pact in 1955). Germany's split occupation zones solidified into East and West Germany in 1949. The first major proxy war of the period was the Korean War from 1950 to 1953, which ended in stalemate. In 1962,

4836-609: The Turkish Straits crisis and Black Sea border disputes were also a major factor in increasing tensions. In September, the Soviet side produced the Novikov telegram, sent by the Soviet ambassador to the US but commissioned and "co-authored" by Vyacheslav Molotov ; it portrayed the US as being in the grip of monopoly capitalists who were building up military capability "to prepare the conditions for winning world supremacy in

4960-415: The United Nations Security Council Resolution 82 and 83 backed the defense of South Korea, although the Soviets were then boycotting meetings in protest of the fact that Taiwan (Republic of China), not the People's Republic of China , held a permanent seat on the council. A UN force of sixteen countries faced North Korea, although 40 percent of troops were South Korean, and about 50 percent were from

5084-487: The University of Texas System partnered with Lockheed-Martin . In December 2005, the Department of Energy announced that LANS had won the next seven-year contract to manage and operate the laboratory. On June 1, 2006, the University of California ended its sixty years of direct involvement in operating Los Alamos National Laboratory, and management control of the laboratory was taken over by Los Alamos National Security, LLC with effect October 1, 2007.

5208-449: The flow cytometry technology. In the 1950s, researcher Mack Fulwyler developed a technique for sorting erythrocytes that combined the Coulter Principle of Coulter counter technologies, which measures the presence of cells and their size, with ink jet technology, which produces a laminar flow of liquid that breaks up into separate, fine drops. In 1969, Los Alamos reported the first fluorescence detector apparatus, which accurately measured

5332-414: The Cold War was in its essence a war of ideas. The United States, acting through the CIA, funded a long list of projects to counter the communist appeal among intellectuals in Europe and the developing world. The CIA also covertly sponsored a domestic propaganda campaign called Crusade for Freedom . The rearmament of West Germany was achieved in the early 1950s. Its main promoter was Konrad Adenauer ,

5456-404: The Cold War, preventing Western food, materials and supplies from arriving in the West Germany's exclave of West Berlin . The United States (primarily), Britain, France, Canada, Australia, New Zealand, and several other countries began the massive "Berlin airlift", supplying West Berlin with food and other provisions despite Soviet threats. The Soviets mounted a public relations campaign against

5580-408: The Communist governments militarily. The fall of the Iron Curtain after the Pan-European Picnic and the Revolutions of 1989 , which represented a peaceful revolutionary wave with the exception of the Romanian revolution and the Afghan Civil War (1989–1992) , overthrew almost all of the Marxist–Leninist regimes of the Eastern Bloc. The Communist Party of the Soviet Union itself lost control in

5704-400: The KGB (1973–1979), described active measures as "the heart and soul of Soviet intelligence ." During the Sino-Soviet split , "spy wars" also occurred between the USSR and PRC. In September 1947, the Soviets created Cominform to impose orthodoxy within the international communist movement and tighten political control over Soviet satellites through coordination of communist parties in

5828-414: The LANL director no longer reports to the UC Regents or UC Office of the President. On June 8, 2018, the NNSA announced that Triad National Security, LLC, a joint venture between Battelle Memorial Institute , the University of California, and Texas A&M University, would assume operation and management of LANL beginning November 1, 2018. In August 2011, the close placement of eight plutonium rods for

5952-412: The LANS contract. The lab was penalized with a $ 57 million reduction in its 2014 budget over the February 14, 2014, accident at the Waste Isolation Pilot Plant for which it was partly responsible. In August 2017, the improper storage of plutonium metal could have triggered a criticality accident , and subsequently staff failed to declare the failure as required by procedure. With support of

6076-413: The Manhattan Project, Los Alamos hosted thousands of employees, including many Nobel Prize -winning scientists. The location was a total secret. Its only mailing address was a post office box, number 1663, in Santa Fe , New Mexico. Eventually two other post office boxes were used, 180 and 1539, also in Santa Fe. Though its contract with the University of California was initially intended to be temporary,

6200-428: The Marshall Plan, seeing it as an effort by the US to impose its influence on Europe. In response, the Soviet Union established Comecon (Council for Mutual Economic Assistance) to foster economic cooperation among communist states. The United States and its Western European allies sought to strengthen their bonds and used the policy of containment against Soviet influence; they accomplished this most notably through

6324-446: The Russian Civil War further complicated relations, and although the Soviet Union later allied with Western powers to defeat Nazi Germany , this cooperation was strained by mutual suspicions. In the immediate aftermath of World War II, disagreements about the future of Europe, particularly Eastern Europe , became central. The Soviet Union's establishment of communist regimes in the countries it had liberated from Nazi control—enforced by

6448-429: The Secretary-Treasurer Robert Underhill, who was in charge of wartime contracts and liabilities. The work of the laboratory culminated in several atomic devices, one of which was used in the first nuclear test near Alamogordo, New Mexico , codenamed " Trinity ", on July 16, 1945. The other two were weapons, " Little Boy " and " Fat Man ", which were used in the attacks on Hiroshima and Nagasaki. The Laboratory received

6572-421: The Soviet Union and its communist party , which had an influence across the Second World and was also tied to a network of authoritarian states. The Soviet Union had a command economy and installed similarly communist regimes its in satellites. United States involvement in regime change during the Cold War included support for anti-communist and right-wing dictatorships , governments, and uprisings across

6696-408: The Soviet Union was used to monitor dissent from official Soviet politics and morals. Although to an extent disinformation had always existed, the term itself was invented, and the strategy formalized by a black propaganda department of the Soviet KGB. Based on the amount of top-secret Cold War archival information that has been released, historian Raymond L. Garthoff concludes there probably

6820-400: The Soviet Union, which at the time was undergoing the Era of Stagnation . This phase saw the new Soviet leader Mikhail Gorbachev introducing the liberalizing reforms of glasnost ("openness") and perestroika ("reorganization") and ending Soviet involvement in Afghanistan in 1989. Pressures for national sovereignty grew stronger in Eastern Europe, and Gorbachev refused to further support

6944-499: The Soviet Union. A number of self-proclaimed Marxist–Leninist governments were formed in the second half of the 1970s in developing countries , including Angola , Mozambique , Ethiopia , Cambodia , Afghanistan , and Nicaragua . Détente collapsed at the end of the decade with the beginning of the Soviet–Afghan War in 1979. Beginning in the 1980s, this phase was another period of elevated tension. The Reagan Doctrine led to increased diplomatic, military, and economic pressures on

7068-455: The Soviets accumulated after broken promises by Stalin and Molotov concerning Europe and Iran. Following the World War II Anglo-Soviet invasion of Iran , the country was occupied by the Red Army in the far north and the British in the south. Iran was used by the United States and British to supply the Soviet Union, and the Allies agreed to withdraw from Iran within six months after the cessation of hostilities. However, when this deadline came,

7192-425: The Soviets agreed to withdraw from Iran after persistent US pressure, an early success of containment policy. By 1947, US president Harry S. Truman was outraged by the perceived resistance of the Soviet Union to American demands in Iran, Turkey, and Greece, as well as Soviet rejection of the Baruch Plan on nuclear weapons. In February 1947, the British government announced that it could no longer afford to finance

7316-404: The Soviets had permitted to retain democratic structures. The public brutality of the coup shocked Western powers more than any event up to that point, set in motion a brief scare that war would occur, and swept away the last vestiges of opposition to the Marshall Plan in the United States Congress. In an immediate aftermath of the crisis, the London Six-Power Conference was held, resulting in

7440-426: The Soviets remained in Iran under the guise of the Azerbaijan People's Government and Kurdish Republic of Mahabad . Shortly thereafter, on 5 March, former British prime minister Winston Churchill delivered his famous " Iron Curtain " speech in Fulton, Missouri . The speech called for an Anglo-American alliance against the Soviets, whom he accused of establishing an "iron curtain" dividing Europe from " Stettin in

7564-455: The Truman Doctrine marked the beginning of a US bipartisan defense and foreign policy consensus between Republicans and Democrats focused on containment and deterrence that weakened during and after the Vietnam War , but ultimately persisted thereafter. Moderate and conservative parties in Europe, as well as social democrats, gave virtually unconditional support to the Western alliance, while European and American Communists , financed by

Under the leadership of Alcide De Gasperi the Italian Christian Democrats defeated the powerful Communist – Socialist alliance in the elections of 1948 . All major powers engaged in espionage, using a great variety of spies, double agents , moles , and new technologies such as the tapping of telephone cables. The Soviet KGB ("Committee for State Security"),

7812-476: The US government gave to Western European countries over $ 13 billion (equivalent to $ 189 billion in 2016) to rebuild the economy of Europe . Later, the program led to the creation of the OECD . The plan's aim was to rebuild the democratic and economic systems of Europe and to counter perceived threats to the European balance of power , such as communist parties seizing control through revolutions or elections. The plan also stated that European prosperity

7936-419: The US was trying to buy a pro-US re-alignment of Europe. Stalin therefore prevented Eastern Bloc nations from receiving Marshall Plan aid. The Soviet Union's alternative to the Marshall Plan, which was purported to involve Soviet subsidies and trade with central and eastern Europe, became known as the Molotov Plan (later institutionalized in January 1949 as the Council for Mutual Economic Assistance ). Stalin

8060-424: The USSR. In this way, this US would exercise " preponderant power ," oppose neutrality, and establish global hegemony . In the early 1950s (a period sometimes known as the " Pactomania "), the US formalized a series of alliances with Japan (a former WWII enemy), South Korea , Taiwan , Australia , New Zealand , Thailand and the Philippines (notably ANZUS in 1951 and SEATO in 1954), thereby guaranteeing

8184-412: The United Nations, was split up and dissolved in 1954 and 1975, also because of the détente between the West and Tito. The US and Britain merged their western German occupation zones into " Bizone " (1 January 1947, later "Trizone" with the addition of France's zone, April 1949). As part of the economic rebuilding of Germany, in early 1948, representatives of a number of Western European governments and

8308-445: The United States a number of long-term military bases. One of the more significant examples of the implementation of containment was the United Nations US-led intervention in the Korean War . In June 1950, after years of mutual hostilities, Kim Il Sung 's North Korean People's Army invaded South Korea at the 38th parallel . Stalin had been reluctant to support the invasion but ultimately sent advisers. To Stalin's surprise,

8432-401: The United States announced an agreement for a merger of western German areas into a federal governmental system. In addition, in accordance with the Marshall Plan , they began to re-industrialize and rebuild the West German economy, including the introduction of a new Deutsche Mark currency to replace the old Reichsmark currency that the Soviets had debased. The US had secretly decided that

8556-450: The Warsaw Pact's primary function was to safeguard Soviet hegemony over its Eastern European satellites, with the pact's only direct military actions having been the invasions of its own member states to keep them from breaking away; in the 1960s, the pact evolved into a multilateral alliance, in which the non-Soviet Warsaw Pact members gained significant scope to pursue their own interests. In 1961, Soviet-allied East Germany constructed

8680-423: The Western agencies paid special attention to debriefing Eastern Bloc defectors . Edward Jay Epstein describes that the CIA understood that the KGB used "provocations", or fake defections, as a trick to embarrass Western intelligence and establish Soviet double agents. As a result, from 1959 to 1973, the CIA required that East Bloc defectors went through a counterintelligence investigation before being recruited as

American policymakers accused the Soviet Union of conspiring against the Greek royalists in an effort to expand Soviet influence even though Stalin had told the Communist Party to cooperate with the British-backed government. Enunciation of

9052-482: The bureau responsible for foreign espionage and internal surveillance, was famous for its effectiveness. The most famous Soviet operation involved its atomic spies that delivered crucial information from the United States' Manhattan Project , leading the USSR to detonate its first nuclear weapon in 1949, four years after the American detonation and much sooner than expected. A massive network of informants throughout

9176-716: The chancellor of West Germany, with France the main opponent. Washington had the decisive voice. It was strongly supported by the Pentagon (the US military leadership), and weakly opposed by President Truman; the State Department was ambivalent. The outbreak of the Korean War in June 1950 changed the calculations and Washington now gave full support. That also involved naming Dwight D. Eisenhower in charge of NATO forces and sending more American troops to West Germany. There

9300-515: The communist party. Radio and television organizations were state-owned, while print media was usually owned by political organizations, mostly by the local communist party. Soviet radio broadcasts used Marxist rhetoric to attack capitalism, emphasizing themes of labor exploitation, imperialism and war-mongering. Along with the broadcasts of the BBC and the Voice of America to Central and Eastern Europe,

This in turn led to the formal dissolution of the Soviet Union in December 1991 and the collapse of Communist governments across much of Africa and Asia. The Russian Federation became the Soviet Union's successor state, while many of the other republics emerged from the Soviet Union's collapse as fully independent post-Soviet states . The United States

9548-490: The country indicated the need for a laboratory dedicated solely to that purpose. General Leslie Groves wanted a central laboratory at an isolated location for safety, and to keep the scientists away from the populace. It should be at least 200 miles from international boundaries and west of the Mississippi. Major John Dudley suggested Oak City, Utah , or Jemez Springs, New Mexico , but both were rejected. Jemez Springs

9672-807: The country's nuclear arsenal. Additional work included basic scientific research, particle accelerator development, health physics, and fusion power research as part of Project Sherwood . Many nuclear tests were undertaken in the Marshall Islands and at the Nevada Test Site . During the late-1950s, a number of scientists including Dr. J. Robert "Bob" Beyster left Los Alamos to work for General Atomics (GA) in San Diego . Three major nuclear-related accidents have occurred at LANL. Criticality accidents occurred in August 1945 and May 1946, and

9796-456: The design and implementation of the major modules" was carried out by Brian Gough and Gerard Jungman. Other major contributors were Jim Davies , Reid Priedhorsky, M. Booth, and F. Rossi. Version 1.0 was released in 2001. In the following years, the library expanded only slowly; as the documentation stated, the maintainers were more interested in stability than in additional functionality. Major version 1 ended with release 1.16 of July 2013; this

9920-695: The effectiveness of the United States' vaccine distribution infrastructure. Additional advancements include the ASPECT airplane that can detect bio threats from the sky. In 2008, development for a safer, more comfortable and accurate test for breast cancer was ongoing by scientists Lianjie Huang and Kenneth M. Hanson and collaborators. The new technique, called ultrasound-computed tomography (ultrasound CT), uses sound waves to accurately detect small tumors that traditional mammography cannot. The lab has made intense efforts for humanitarian causes through its scientific research in medicine. In 2010, three vaccines for

10044-461: The environment. It also contributed to thousands of dumpsites at 108 locations in 29 US states. Continuing efforts to make the laboratory more efficient led the Department of Energy to open its contract with the University of California to bids from other vendors in 2003. Though the university and the laboratory had difficult relations many times since their first World War II contract, this was

10168-471: The expertise and resources in genome mapping , DNA sequencing , technology development, and information sciences pioneered at the three genome centers at University of California's Lawrence Berkeley National Laboratory (LBNL), Lawrence Livermore National Laboratory (LLNL), and LANL. The Integrated Computing Network (ICN) is a multi-security level network at the LANL integrating large host supercomputers,

10292-463: The fall of the communist governments of Europe from 1989, which concluded with the fall of the Soviet Union in 1991. The Western Bloc included the US and a number of First World nations that were generally capitalist and liberal democratic but tied to a network of often authoritarian Third World states, most of which were the European powers' former colonies . The Eastern Bloc was led by

10416-500: The federal government, LANL is privately managed and operated by Triad National Security, LLC . The laboratory was founded during World War II as a secret, centralized facility to coordinate the scientific research of the Manhattan Project , the Allied project to develop the first nuclear weapons . In September 1942, the difficulties encountered in conducting preliminary studies on nuclear weapons at universities scattered across

10540-542: The first time that the university ever had to compete for management of the laboratory. The University of California decided to create a private company with the Bechtel Corporation, Washington Group International , and the BWX Technologies to bid on the contract to operate the laboratory. The UC/Bechtel led corporation— Los Alamos National Security, LLC (LANS)—was pitted against a team formed by

10664-401: The formation of NATO , which was essentially a defensive agreement in 1949. The Soviet Union countered with the Warsaw Pact in 1955, which had similar results with the Eastern Bloc. As by that time the Soviet Union already had an armed presence and political domination all over its eastern satellite states, the pact has been long considered superfluous. Although nominally a defensive alliance,

10788-499: The former 10,000 plus UC employees at LANL were rehired by LANS to continue working at LANL. Other than UC appointing three members to the eleven member board of directors that oversees LANS, UC now has virtually no responsibility or direct involvement in LANL. UC policies and regulations that apply to UC campuses and its two national laboratories in California ( Lawrence Berkeley and Lawrence Livermore ) no longer apply to LANL, and

10912-636: The growth of infectious diseases . Digital epidemiologists at the lab's Information Systems and Modeling group are using clinical surveillance data, Google search queries, census data, Misplaced Pages , and even tweets to create a system that could predict epidemics. The team is using data from Brazil as its model; Brazil was notably threatened by the Zika virus as it prepared to host the Summer Olympics in 2016 . Within LANL's 43-square-mile property are approximately 2,000 dumpsites which have contaminated

11036-529: The kind of world-view, the kind of beliefs, and the social structure that would probably prevail in a state which was at once unconquerable and in a permanent state of "cold war" with its neighbours. In The Observer of 10 March 1946, Orwell wrote, "...after the Moscow conference last December, Russia began to make a 'cold war' on Britain and the British Empire." The first use of the term to describe

11160-521: The lab to increase research for "non-war" science and technology. Los Alamos' nuclear work is currently thought to relate primarily to computer simulations and stockpile stewardship . The development of the Dual-Axis Radiographic Hydrodynamic Test Facility will allow complex simulations of nuclear tests to take place without full explosive yields. The laboratory contributed to the early development of

11284-448: The lab. After ten months in jail, Lee pleaded guilty to a single count and the other 58 were dismissed with an apology from U.S. District Judge James Parker for his incarceration. Lee had been suspected for having shared U.S. nuclear secrets with China , but investigators were never able to establish what Lee did with the downloaded data. In 2000, two computer hard drives containing classified data were announced to have gone missing from

11408-490: The laboratory and became outspoken opponents to the further development of nuclear weapons. The name officially changed to the Los Alamos Scientific Laboratory ( LASL ) on January 1, 1947. By this time, Argonne had already been made the first National Laboratory the previous year. Los Alamos would not become a National Laboratory in name until 1981. In the years since the 1940s, Los Alamos

11532-490: The largest employer with approximately 8,762 direct employees, 277 guard force, 505 contractors, 1,613 students, 1,143 unionized craft workers, and 452 post-doctoral researchers. Additionally, there are roughly 120 DOE employees stationed at the laboratory to provide federal oversight of LANL's work and operations. Approximately one-third of the laboratory's technical staff members are physicists , one-quarter are engineers , one-sixth are chemists and materials scientists , and

11656-402: The loyalty of non-aligned countries , such as India . By the 1970s, Japan and Western Europe rebuilt their economies, allowing them more diplomatic independence. After the Sino-Soviet split between the USSR and China in 1961, the U.S. initiated contacts with China in 1972 . In the same year, the US and USSR signed a series of treaties limiting their nuclear arsenals, which eased tensions for

11780-490: The main hub for conducting and coordinating nuclear research, bringing together scientists from around the world, among them numerous Nobel Prize winners. The town of Los Alamos , directly north of the lab, grew extensively through this period. After the war ended in 1945, Project Y's existence was made public, and it became known universally as Los Alamos. In 1952, the Atomic Energy Commission formed

11904-414: The most prominent architects of America's early Cold War strategy, especially those who believed that the Cold War would eventually be fought by political rather than military means, such as George F. Kennan. Soviet and Eastern Bloc authorities used various methods to suppress Western broadcasts, including radio jamming . American policymakers, including Kennan and John Foster Dulles , acknowledged that

12028-406: The number and size of ovarian cells and blood cells. As of 2017, other research performed at the lab included developing cheaper, cleaner biofuels and advancing scientific understanding around renewable energy. Non-nuclear national security and defense development is also a priority at the lab. This includes preventing outbreaks of deadly diseases by improving detection tools and the monitoring

12152-671: The policy change. Once again, the East Berlin communists attempted to disrupt the Berlin municipal elections , which were held on 5 December 1948 and produced a turnout of 86% and an overwhelming victory for the non-communist parties. The results effectively divided the city into East and West, the latter comprising US, British and French sectors. 300,000 Berliners demonstrated and urged the international airlift to continue, and US Air Force pilot Gail Halvorsen created " Operation Vittles ", which supplied candy to German children. The Airlift

12276-441: The political decision-making level on either side. Similarly, there is no evidence, on either side, of any major political or military decision that was prematurely discovered through espionage and thwarted by the other side. There also is no evidence of any major political or military decision that was crucially influenced (much less generated) by an agent of the other side. According to historian Robert L. Benson, "Washington's forte

12400-479: The presence of the Red Army —alarmed the US and UK. Western leaders saw this as a clear instance of Soviet expansionism, clashing with their vision of a democratic Europe. Economically, the divide was sharpened with the introduction of the Marshall Plan in 1947, a US initiative to provide financial aid to rebuild Europe and prevent the spread of communism by stabilizing capitalist economies. The Soviet Union rejected

12524-447: The relationship was maintained long after the war. Until the atomic bombings of Hiroshima and Nagasaki , Japan , University of California president Robert Sproul did not know what the purpose of the laboratory was and thought it might be producing a " death ray ". The only member of the UC administration who knew its true purpose—indeed, the only one who knew its exact physical location—was

12648-440: The remainder work in mathematics and computational science , biology , geoscience , and other disciplines. Professional scientists and students also come to Los Alamos as visitors to participate in scientific projects. The staff collaborates with universities and industry in both basic and applied research to develop resources for the future. The annual budget is approximately US$ 2.2 billion. Cold War The Cold War

12772-469: The source of the term, Lippmann traced it to a French term from the 1930s, la guerre froide . The roots of the Cold War can be traced back to diplomatic and military tensions preceding World War II. The 1917 Russian Revolution and the subsequent Treaty of Brest-Litovsk , where Soviet Russia ceded vast territories to Germany, deepened distrust among the Western Allies. Allied intervention in

12896-463: The specific post-war geopolitical confrontation between the Soviet Union and the United States came in a speech by Bernard Baruch , an influential advisor to Democratic presidents, on 16 April 1947. The speech, written by journalist Herbert Bayard Swope , proclaimed, "Let us not be deceived: we are today in the midst of a cold war." Newspaper columnist Walter Lippmann gave the term wide currency with his book The Cold War . When asked in 1947 about

13020-405: The two superpowers , though each supported opposing sides in major regional conflicts known as proxy wars . Aside from the nuclear arms race starting in 1949 and conventional military deployment , the struggle for dominance was expressed indirectly via psychological warfare , propaganda campaigns , espionage , far-reaching embargoes , sports diplomacy , and technological competitions such as

13144-411: The world, while Soviet involvement in regime change included the funding of left-wing parties , wars of independence , revolutions and dictatorships. As nearly all the colonial states underwent decolonization and achieved independence in the period from 1945 to 1960, many became Third World battlefields in the Cold War. At the end of World War II, English writer George Orwell used cold war , as

13268-486: The world. Movements against nuclear weapons testing and for nuclear disarmament took place, with large anti-war protests . By the 1970s, both sides had started making allowances for peace and security, ushering in a period of détente that saw the Strategic Arms Limitation Talks and the 1972 visit by Richard Nixon to China that opened relations with China as a strategic counterweight to

13392-505: Was 'signals' intelligence - the procurement and analysis of coded foreign messages." leading to the Venona project or Venona intercepts, which monitored the communications of Soviet intelligence agents. Moynihan wrote that the Venona project contained "overwhelming proof of the activities of Soviet spy networks in America, complete with names, dates, places, and deeds." The Venona project

13516-606: Was a period of global geopolitical tension and struggle for ideological and economic influence between the United States and the Soviet Union (USSR) and their respective allies, the Western Bloc and the Eastern Bloc , that started in 1947, two years after the end of World War II , and lasted until the fall of the Soviet Union in 1991. The term cold war is used because there was no direct fighting between

13640-412: Was a strong promise that West Germany would not develop nuclear weapons. Widespread fears of another rise of German militarism necessitated the new military to operate within an alliance framework under NATO command. In 1955, Washington secured full German membership of NATO. In May 1953, Lavrentiy Beria , by then in a government post, had made an unsuccessful proposal to allow the reunification of

13764-567: Was also fearful of a reconstituted Germany; his vision of a post-war Germany did not include the ability to rearm or pose any kind of threat to the Soviet Union. In early 1948, following reports of strengthening "reactionary elements", Czech Communists executed a coup d'état in Czechoslovakia (resulting in the formation of the Czechoslovak Socialist Republic (9 May 1948)), the only Eastern Bloc state that

13888-548: Was as much a logistical as a political and psychological success for the West; it firmly linked West Berlin to the United States. In May 1949, Stalin backed down and lifted the blockade. In 1952, Stalin repeatedly proposed a plan to unify East and West Germany under a single government chosen in elections supervised by the United Nations, if the new Germany were to stay out of Western military alliances, but this proposal

14012-679: Was contingent upon German economic recovery. One month later, Truman signed the National Security Act of 1947 , creating a unified Department of Defense , the Central Intelligence Agency (CIA), and the National Security Council (NSC). These would become the main bureaucracies for US defense policy in the Cold War. Stalin believed economic integration with the West would allow Eastern Bloc countries to escape Soviet control, and that

14136-786: Was initially developed at LANL. In the recent years, the Laboratory has developed a major research program in systems biology modeling , known at LANL under the name q-bio. Several serials are published by LANL: LANL also published Los Alamos Science from 1980 to 2005, as well as the Nuclear Weapons Journal , which was replaced by National Security Science after two issues in 2009. In 2005, Congress held new hearings on lingering security issues at Los Alamos National Weapons Laboratory in New Mexico; documented problems continued to be ignored. In November 2008,

14260-472: Was kept highly secret even from policymakers until the Moynihan Commission in 1995. Despite this, the decryption project had already been betrayed and dispatched to the USSR by Kim Philby and Bill Weisband in 1946, as was discovered by the US by 1950. Nonetheless, the Soviets had to keep their discovery of the program secret, too, and continued leaking their own information, some of which

14384-506: Was left as the world's sole superpower. In February 1946, George F. Kennan 's " Long Telegram " from Moscow to Washington helped to articulate the US government's increasingly hard line against the Soviets, which would become the basis for US strategy toward the Soviet Union for the duration of the Cold War. The telegram galvanized a policy debate that would eventually shape the Truman administration 's Soviet policy. Washington's opposition to

14508-545: Was now restricted to the island of Taiwan , the nationalist government of which exists to this day. The Kremlin promptly created an alliance with the newly formed People's Republic of China. According to Norwegian historian Odd Arne Westad , the communists won the Civil War because they made fewer military mistakes than Chiang Kai-Shek made, and because in his search for a powerful centralized government, Chiang antagonized too many interest groups in China. Moreover, his party

14632-497: Was only a short distance from the current site. Project Y director J. Robert Oppenheimer had spent much time in his youth in the New Mexico area and suggested the Los Alamos Ranch School on the mesa . Dudley had rejected the school as not meeting Groves' criteria, but as soon as Groves saw it he said in effect "This is the place". Oppenheimer became the laboratory's first director; from 19 October 1942. During

14756-403: Was parity in the quantity and quality of secret information obtained by each side. However, the Soviets probably had an advantage in terms of HUMINT (human intelligence or interpersonal espionage) and "sometimes in its reach into high policy circles." In terms of decisive impact, however, he concludes: We also can now have high confidence in the judgment that there were no successful "moles" at

14880-419: Was responsible for the development of the hydrogen bomb , and many other variants of nuclear weapons. In 1952, Lawrence Livermore National Laboratory was founded to act as Los Alamos' "competitor", with the hope that two laboratories for the design of nuclear weapons would spur innovation. Los Alamos and Livermore served as the primary classified laboratories in the U.S. national laboratory system, designing all

15004-427: Was still useful to the American program. According to Moynihan, even President Truman may not have been fully informed of Venona, which may have left him unaware of the extent of Soviet espionage. Clandestine atomic spies from the Soviet Union, who infiltrated the Manhattan Project at various points during WWII, played a major role in increasing tensions that led to the Cold War. In addition to usual espionage,

15128-591: Was the only public activity in the three years 2012–2014. Vigorous development resumed with publication of version 2.0 in October 2015, which included user contributed patches. The latest version 2.8 was released in May 2024. The following example program calculates the value of the Bessel function of the first kind and order zero for 5: The example program has to be linked to the GSL library upon compilation: The output

15252-655: Was turned down by the Western powers. Some sources dispute the sincerity of the proposal. Britain, France, the United States, Canada and eight other western European countries signed the North Atlantic Treaty of April 1949, establishing the North Atlantic Treaty Organization (NATO). That August, the first Soviet atomic device was detonated in Semipalatinsk , Kazakh SSR . Following Soviet refusals to participate in

15376-487: Was weakened during the war against Japan . Meanwhile, the communists told different groups, such as the peasants, exactly what they wanted to hear, and they cloaked themselves under the cover of Chinese nationalism . Confronted with the communist revolution in China and the end of the American atomic monopoly in 1949, the Truman administration quickly moved to escalate and expand its containment doctrine. In NSC 68 ,
