Alfred Epaminondas Sarant, also known as Filipp Georgievich Staros and Philip Georgievich Staros (September 26, 1918 – March 12, 1979), was an engineer and a member of the Communist party in New York City in 1944. He was part of the Rosenberg spy ring that reported to Soviet intelligence. Sarant worked on secret military radar at the United States Army Signal Corps laboratories at Fort Monmouth, New Jersey. Alexandre Feklisov, one of the KGB case officers who handled the Rosenberg spy apparatus described Sarant and Joel Barr as among the most productive members of the group. Sarant was recruited as a Soviet espionage agent by Barr. Biography A member of the Communist Party of the United States (CPUSA) during the Second World War, Sarant worked at the nuclear physics laboratory of Cornell University. In 1941, Julius Rosenberg and Joel Barr were recruited as Soviet spies by Jacob Golos. They in turn persuaded Sarant to join the network. According to Alexander Feklissov: ...

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 Multiculturalism, 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 Immigration to Canada, immigrants and their descendants. Following the initial period of New France, French and then the much larger British colonization of the Americas, 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 ...

Richard Feynman
Richard Phillips Feynman (; May 11, 1918 – February 15, 1988) was an American theoretical physicist, known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, the physics of the superfluidity of supercooled liquid helium, as well as his work in particle physics for which he proposed the parton model. For contributions to the development of quantum electrodynamics, Feynman received the Nobel Prize in Physics in 1965 jointly with Julian Schwinger and Shin'ichirō Tomonaga. Feynman developed a widely used pictorial representation scheme for the mathematical expressions describing the behavior of subatomic particles, which later became known as Feynman diagrams. During his lifetime, Feynman became one of the best-known scientists in the world. In a 1999 poll of 130 leading physicists worldwide by the British journal ''Physics World'', he was ranked the seventh-greatest physicist of all time. He assisted in the development o ...

Communist Party Of The United States
The Communist Party USA, officially the Communist Party of the United States of America (CPUSA), is a communist party in the United States which was established in 1919 after a split in the Socialist Party of America following the Russian Revolution. The history of the CPUSA is closely related to the history of the American labor movement and the history of communist parties worldwide. Initially operating underground due to the Palmer Raids which started during the First Red Scare, the party was influential in American politics in the first half of the 20th century and it also played a prominent role in the history of the labor movement from the 1920s through the 1940s, becoming known for opposing racism and racial segregation after sponsoring the defense for the Scottsboro Boys in 1931. Its membership increased during the Great Depression, and it also played a key role in the founding of the Congress of Industrial Organizations. The CPUSA subsequently declined due to events ...

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 ...

Laboratories
A laboratory (; ; colloquially lab) is a facility that provides controlled conditions in which scientific or technological research, experiments, and measurement may be performed. Laboratory services are provided in a variety of settings: physicians' offices, clinics, hospitals, and regional and national referral centers. Overview The organisation and contents of laboratories are determined by the differing requirements of the specialists working within. A physics laboratory might contain a particle accelerator or vacuum chamber, while a metallurgy laboratory could have apparatus for casting or refining metals or for testing their strength. A chemist or biologist might use a wet laboratory, while a psychologist's laboratory might be a room with one-way mirrors and hidden cameras in which to observe behavior. In some laboratories, such as those commonly used by computer scientists, computers (sometimes supercomputers) are used for either simulations or the analysis of data. Scienti ...
