Electromagnetic Isotope Separation
A calutron is a mass spectrometer originally designed and used for separating the isotopes of uranium. It was developed by Ernest Lawrence during the Manhattan Project and was based on his earlier invention, the cyclotron. Its name was derived from California University Cyclotron, in tribute to Lawrence's institution, the University of California, where it was invented. Calutrons were used in the industrial-scale Y-12 uranium enrichment plant at the Clinton Engineer Works in Oak Ridge, Tennessee. The enriched uranium produced was used in the Little Boy atomic bomb that was detonated over Hiroshima on 6 August 1945. The calutron is a type of sector mass spectrometer, an instrument in which a sample is ionized and then accelerated by electric fields and deflected by magnetic fields. The ions ultimately collide with a plate and produce a measurable electric current. Since the ions of the different isotopes have the same electric charge but different masses, the heavier isot ...

Brigadier General (United States)
In the United States Armed Forces, a brigadier general is a one-star general officer in the United States Army, Marine Corps, Air Force, and Space Force. A brigadier general ranks above a colonel and below a major general. The pay grade of brigadier general is O-7. It is equivalent to the rank of rear admiral (lower half) in the other United States uniformed services which use naval ranks. It is abbreviated as BG in the Army, BGen in the Marine Corps, and Brig Gen in the Air Force and Space Force. History The rank of brigadier general has existed in the U.S. military since the inception of the Continental Army in June 1775. To prevent mistakes in recognizing officers, a general order was issued on July 14, 1775, establishing that brigadier generals would wear a ribbon, worn across the breast, between coat and waistcoat, pink in color. Later, on June 18, 1780, it was prescribed that brigadier generals would instead wear a single silver star on each epaulette. At first, briga ...

General Leslie R
A general officer is an officer of high rank in the armies, and in some nations' air forces, space forces, and marines or naval infantry. In some usages the term "general officer" refers to a rank above colonel."general, adj. and n.". OED Online. March 2021. Oxford University Press. https://www.oed.com/view/Entry/77489?rskey=dCKrg4&result=1 (accessed May 11, 2021) The term ''general'' is used in two ways: as the generic title for all grades of general officer and as a specific rank. It originates in the 16th century, as a shortening of '' captain general'', which rank was taken from Middle French ''capitaine général''. The adjective ''general'' had been affixed to officer designations since the late medieval period to indicate relative superiority or an extended jurisdiction. Today, the title of ''general'' is known in some countries as a four-star rank. However, different countries use different systems of stars or other insignia for senior ranks. It has a NATO r ...

Office Of Scientific Research And Development
The Office of Scientific Research and Development (OSRD) was an agency of the United States federal government created to coordinate scientific research for military purposes during World War II. Arrangements were made for its creation during May 1941, and it was created formally by Executive Order 8807 on June 28, 1941. It superseded the work of the National Defense Research Committee (NDRC), was given almost unlimited access to funding and resources, and was directed by Vannevar Bush, who reported only to President Franklin Delano Roosevelt. The research was widely varied, and included projects devoted to new and more accurate bombs, reliable detonators, work on the proximity fuze, guided missiles, radar and early-warning systems, lighter and more accurate hand weapons, more effective medical treatments (including work to make penicillin at scale, which was necessary for its use as a drug), more versatile vehicles, and, the most secret of all, the S-1 Section, which later be ...

First Lieutenant
First lieutenant is a commissioned officer military rank in many armed forces; in some forces, it is an appointment. The rank of lieutenant has different meanings in different military formations, but in most forces it is sub-divided into a senior (first lieutenant) and junior (second lieutenant) rank. The NATO equivalent rank for land force officers is OF-1 rank. In navies, while certain rank insignia may carry the name lieutenant, the term may also be used to relate to a particular post or duty, rather than a rank. Indonesia In Indonesia, "first lieutenant" is known as ''Letnan Satu'' (''Lettu''), Indonesian National Armed Forces uses this rank across all three of its services. It is just above the rank of second lieutenant and just below the rank of captain. Israel In the Israel Defense Forces, the rank above second lieutenant is simply lieutenant.

Ithaca, New York
Ithaca is a city in the Finger Lakes region of New York, United States. Situated on the southern shore of Cayuga Lake, Ithaca is the seat of Tompkins County and the largest community in the Ithaca metropolitan statistical area. It is named after the Greek island of Ithaca. A college town, Ithaca is home to Cornell University and Ithaca College. Nearby is Tompkins Cortland Community College (TC3). These three colleges bring thousands of students to the area, who increase Ithaca's seasonal population during the school year. As of 2020, the city's population was 32,108. History Early history Native Americans lived in this area for thousands of years. When reached by Europeans, this area was controlled by the Cayuga tribe of Indians, one of the Five Nations of the ''Haudenosaunee'' or Iroquois League. Jesuit missionaries from New France (Quebec) are said to have had a mission to convert the Cayuga as early as 1657. Saponi and Tutelo peoples, Siouan-speaking tribes, lat ...

Reserve Officers' Training Corps
The Reserve Officers' Training Corps (ROTC ( or )) is a group of college- and university-based officer-training programs for training commissioned officers of the United States Armed Forces. Overview While ROTC graduate officers serve in all branches of the U.S. military, the U.S. Marine Corps, the U.S. Space Force, and the U.S. Coast Guard do not have their own respective ROTC programs; rather, graduates of Naval ROTC programs have the option to serve as officers in the Marine Corps contingent on meeting Marine Corps requirements. In 2020, ROTC graduates constituted 70 percent of newly commissioned active-duty U.S. Army officers, 83 percent of newly commissioned U.S. Marine Corps officers (through NROTC), 61 percent of newly commissioned U.S. Navy officers and 63 percent of newly commissioned U.S. Air Force officers, for a combined 56 percent of all active-duty officers in the Department of Defense commissioned that year.

Doctor Of Science
Doctor of Science ( la, links=no, Scientiae Doctor), usually abbreviated Sc.D., D.Sc., S.D., or D.S., is an academic research degree awarded in a number of countries throughout the world. In some countries, "Doctor of Science" is the degree used for the standard doctorate in the sciences; elsewhere the Sc.D. is a "higher doctorate" awarded in recognition of a substantial and sustained contribution to scientific knowledge beyond that required for a Doctor of Philosophy (PhD). Africa Algeria and Morocco In Algeria, Morocco, Libya and Tunisia, all universities accredited by the state award a "Doctorate" in all fields of science and humanities, equivalent to a PhD in the United Kingdom or United States. Some universities in these four Arab countries award a "Doctorate of the State" in some fields of study and science. A "Doctorate of the State" is slightly higher in esteem than a regular doctorate, and is awarded after performing additional in-depth post-doctorate research or ach ...

Master Of Science
A Master of Science ( la, Magisterii Scientiae; abbreviated MS, M.S., MSc, M.Sc., SM, S.M., ScM or Sc.M.) is a master's degree in the field of science awarded by universities in many countries or a person holding such a degree. In contrast to the Master of Arts degree, the Master of Science degree is typically granted for studies in sciences, engineering and medicine and is usually for programs that are more focused on scientific and mathematical subjects; however, different universities have different conventions and may also offer the degree for fields typically considered within the humanities and social sciences. While it ultimately depends upon the specific program, earning a Master of Science degree typically includes writing a thesis. The Master of Science degree was first introduced at the University of Michigan in 1858. One of the first recipients of the degree was De Volson Wood, who was conferred a Master of Science degree at the University of Michigan in 1859. Al ...

Contra Costa Times
The ''East Bay Times'' is a daily broadsheet newspaper based in Walnut Creek, California, United States, owned by the Bay Area News Group (BANG), a subsidiary of Media News Group, that serves Contra Costa and Alameda counties, in the East Bay region of the San Francisco Bay Area. It was founded as the ''Contra Costa Times'', and took its current name in 2016 when it was merged with other sister papers in the East Bay. Its oldest merged title is the ''Oakland Tribune'' founded in 1874. History The original ''Contra Costa Times'' was founded by Dean Lesher in 1947, and served central Contra Costa County, especially Walnut Creek. However, Lesher began expanding by purchasing weekly newspapers in neighboring communities, as well as two eastern Contra Costa daily papers, the '' Antioch Ledger'' and the ''Pittsburg Post-Dispatch''. Originally the weekly newspapers were free for shoppers, but Lesher gradually converted the papers to "controlled circulation" in 1962, an aggressive a ...
