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the project was designated the Manhattan District as its first headquarters were in Manhattan; the placename gradually superseded the official codename, Development of Substitute Materials, for the entire project.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 ...

Towson, Maryland
Towson () is an unincorporated community and a census-designated place in Baltimore County, Maryland, United States. The population was 55,197 as of the 2010 census. It is the county seat of Baltimore County and the second-most populous unincorporated county seat in the United States (after Ellicott City, the seat of nearby Howard County, southwest of Baltimore). History 1600s The first inhabitants of the future Towson and central Baltimore County region were the Susquehannock people, who hunted in the area. Their region included all of Baltimore County, though their primary settlement was farther northeast along the Susquehanna River. 1700s Towson was settled in 1752 when Pennsylvania brothers, William and Thomas Towson, began farming an area of Sater's Hill, northeast of the present-day York and Joppa Roads. William's son, Ezekiel, opened the Towson Hotel to serve the growing number of farmers bringing their produce and livestock to the port of Baltimore. He built the hote ...

United States Atomic Energy Commission
The United States Atomic Energy Commission (AEC) was an agency of the United States government established after World War II by U.S. Congress to foster and control the peacetime development of atomic science and technology. President Harry S. Truman signed the McMahon/Atomic Energy Act on August 1, 1946, transferring the control of atomic energy from military to civilian hands, effective on January 1, 1947. This shift gave the members of the AEC complete control of the plants, laboratories, equipment, and personnel assembled during the war to produce the atomic bomb. An increasing number of critics during the 1960s charged that the AEC's regulations were insufficiently rigorous in several important areas, including radiation protection standards, nuclear reactor safety, plant siting, and environmental protection. By 1974, the AEC's regulatory programs had come under such strong attack that the U.S. Congress decided to abolish the AEC. The AEC was abolished by the Ener ...

Investigative Journalist
Investigative journalism is a form of journalism in which reporters deeply investigate a single topic of interest, such as serious crimes, political corruption, or corporate wrongdoing. An investigative journalist may spend months or years researching and preparing a report. Practitioners sometimes use the terms "watchdog reporting" or "accountability reporting." Most investigative journalism has traditionally been conducted by newspapers, wire services, and freelance journalists. With the decline in income through advertising, many traditional news services have struggled to fund investigative journalism, due to it being very time-consuming and expensive. Journalistic investigations are increasingly carried out by news organizations working together, even internationally (as in the case of the Panama Papers and Paradise Papers), or by organizations such as ProPublica, which have not operated previously as news publishers and which rely on the support of the public and benefacto ...

Cambridge Spy Ring
The Cambridge Spy Ring was a ring of spies in the United Kingdom that passed information to the Soviet Union during World War II and was active from the 1930s until at least into the early 1950s. None of the known members were ever prosecuted for spying. The number and membership of the ring emerged slowly, from the 1950s onwards. The general public first became aware of the conspiracy after the sudden flight of Donald Maclean (cryptonym: Homer) and Guy Burgess (cryptonym: Hicks) to the Soviet Union in 1951. Suspicion immediately fell on Harold "Kim" Philby (cryptonyms: Sonny, Stanley), who eventually fled the country in 1963. Following Philby's flight, British intelligence obtained confessions from Anthony Blunt (cryptonym: Johnson) and then John Cairncross (cryptonym: Liszt), who have come to be seen as the last two of a group of five. Their involvement was kept secret for many years: until 1979 for Blunt, and 1990 for Cairncross. The moniker Cambridge Four evolved to become ...

Radium
Radium is a chemical element with the symbol Ra and atomic number 88. It is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals. Pure radium is silvery-white, but it readily reacts with nitrogen (rather than oxygen) upon exposure to air, forming a black surface layer of radium nitride (Ra3N2). All isotopes of radium are radioactive, the most stable isotope being radium-226 with a half-life of 1600 years. When radium decays, it emits ionizing radiation as a by-product, which can excite fluorescent chemicals and cause radioluminescence. Radium, in the form of radium chloride, was discovered by Marie and Pierre Curie in 1898 from ore mined at Jáchymov. They extracted the radium compound from uraninite and published the discovery at the French Academy of Sciences five days later. Radium was isolated in its metallic state by Marie Curie and André-Louis Debierne through the electrolysis of radium chloride in 1911. In nature, radium is found ...

National Bureau Of Standards
The National Institute of Standards and Technology (NIST) is an agency of the United States Department of Commerce whose mission is to promote American innovation and industrial competitiveness. NIST's activities are organized into physical science laboratory programs that include nanoscale science and technology, engineering, information technology, neutron research, material measurement, and physical measurement. From 1901 to 1988, the agency was named the National Bureau of Standards. History Background The Articles of Confederation, ratified by the colonies in 1781, provided: The United States in Congress assembled shall also have the sole and exclusive right and power of regulating the alloy and value of coin struck by their own authority, or by that of the respective states—fixing the standards of weights and measures throughout the United States. Article 1, section 8, of the Constitution of the United States, ratified in 1789, granted these powers to the new Congre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
