Dorothy Vaughan
Dorothy Jean Johnson Vaughan (September 20, 1910 – November 10, 2008) was an American mathematician and human computer who worked for the National Advisory Committee for Aeronautics (NACA), and NASA, at Langley Research Center in Hampton, Virginia. In 1949, she became acting supervisor of the West Area Computers, the first African-American woman to receive a promotion and supervise a group of staff at the center. She later was promoted officially to the position of supervisor. During her 28-year career, Vaughan prepared for the introduction of computers in the early 1960s by teaching herself and her staff the programming language of Fortran. She later headed the programming section of the Analysis and Computation Division (ACD) at Langley. Vaughan is one of the women featured in Margot Lee Shetterly's history '' Hidden Figures: The Story of the African-American Women Who Helped Win the Space Race'' (2016). It was adapted as a biographical film of the same name, also releas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kansas City, Missouri
Kansas City (abbreviated KC or KCMO) is the largest city in Missouri by population and area. As of the 2020 census, the city had a population of 508,090 in 2020, making it the 36th most-populous city in the United States. It is the central city of the Kansas City metropolitan area, which straddles the Missouri–Kansas state line and has a population of 2,392,035. Most of the city lies within Jackson County, with portions spilling into Clay, Cass, and Platte counties. Kansas City was founded in the 1830s as a port on the Missouri River at its confluence with the Kansas River coming in from the west. On June 1, 1850, the town of Kansas was incorporated; shortly after came the establishment of the Kansas Territory. Confusion between the two ensued, and the name Kansas City was assigned to distinguish them soon after. Sitting on Missouri's western boundary with Kansas, with Downtown near the confluence of the Kansas and Missouri Rivers, the city encompasses about , making ...

Wilberforce, Ohio
Wilberforce is a census-designated place (CDP) in Greene County, Ohio, United States. The population was 2,271 at the 2010 census, up from 1,579 at the 2000 census. History After Wilberforce College was established in 1856, the community was also named for the English statesman William Wilberforce, who worked for the abolition of slavery and achieved the end of the slave trade in the United Kingdom and its empire. The small community served as an important stop for refugee slaves on the Underground Railroad before the American Civil War, as it had seven stations. The Ohio Historical Society operates the National Afro-American Museum and Cultural Center, which provides exhibits and learning opportunities for the regional community. The Association of African American Museums, also located in Wilberforce and supported by the private university, works to build professional capacity among smaller museums.

Computer Programming
Computer programming is the process of performing a particular computation (or more generally, accomplishing a specific computing result), usually by designing and building an executable computer program. Programming involves tasks such as analysis, generating algorithms, profiling algorithms' accuracy and resource consumption, and the implementation of algorithms (usually in a chosen programming language, commonly referred to as coding). The source code of a program is written in one or more languages that are intelligible to programmers, rather than machine code, which is directly executed by the central processing unit. The purpose of programming is to find a sequence of instructions that will automate the performance of a task (which can be as complex as an operating system) on a computer, often for solving a given problem. Proficient programming thus usually requires expertise in several different subjects, including knowledge of the application domain, specialized algori ...

Scout (rocket Family)
The Scout family of rockets were American launch vehicles designed to place small satellites into orbit around the Earth. The Scout multistage rocket was the first orbital launch vehicle to be entirely composed of solid fuel stages. It was also the only vehicle of that type until the successful launch of the Japanese Lambda 4S in 1970. The original Scout (an acronym for Solid Controlled Orbital Utility Test system) was designed in 1957 at the NACA, at Langley center. Scout launch vehicles were used from 1961 until 1994. To enhance reliability the development team opted to use "off the shelf" hardware, originally produced for military programs. According to the NASA fact sheet: "... the first stage motor was a combination of the Jupiter Senior and the Navy Polaris; the second stage came from the Army MGM-29 Sergeant; and the third and fourth stage motors were designed by Langley engineers who adapted a version of the Navy Vanguard." The first successful orbital launch of a Sco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flight Path
In the United States, airways or air routes are defined by the Federal Aviation Administration (FAA) in two ways: "VOR Federal airways and Low/Medium Frequency (L/MF) (Colored) Federal airways" These are designated routes which aeroplanes fly to aid in navigation and help with separation to avoid accidents. Airways are defined with segments within a specific altitude block, corridor width, and between fixed geographic coordinates for satellites navigation system, or between ground-based radio transmitter navigational aids (navaids; such as VORs or NDBs) or the intersection of specific radials of two navaids. United States To guide airmail pilots on their delivery routes, the United States Postal Service constructed the first airways in the United States, the Contract Air Mail routes. These airways were between major cities and identified at night by a series of flashing lights and beacons which pilots flew over in sequence to get from one city to the next. Intermediate ...

New York (magazine)
''New York'' is an American biweekly magazine concerned with life, culture, politics, and style generally, and with a particular emphasis on New York City. Founded by Milton Glaser and Clay Felker in 1968 as a competitor to ''The New Yorker'', it was brasher and less polite, and established itself as a cradle of New Journalism. Over time, it became more national in scope, publishing many noteworthy articles on American culture by writers such as Tom Wolfe, Jimmy Breslin, Nora Ephron, John Heilemann, Frank Rich, and Rebecca Traister. In its 21st-century incarnation under editor-in-chief Adam Moss, "The nation's best and most-imitated city magazine is often not about the city—at least not in the overcrowded, traffic-clogged, five-boroughs sense", wrote then-''Washington Post'' media critic Howard Kurtz, as the magazine increasingly published political and cultural stories of national significance. Since its redesign and relaunch in 2004, the magazine has won more National Mag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fair Employment Practice Committee

Executive Order 8802
Executive Order 8802 was signed by President of the United States, President Franklin D. Roosevelt on June 25, 1941, to prohibit ethnic or racial discrimination in the nation's defense industry. It also set up the Fair Employment Practice Committee. It was the first federal action, though not a law, to promote equal opportunity and prohibit employment discrimination in the United States. Many citizens of Italian or German ethnicity were affected by World War II and this was impeding the war effort and lowering morale. This ethnic factor was a major motivation for Roosevelt. The President's statement that accompanied the Order cited the war effort, saying that "the democratic way of life within the nation can be defended successfully only with the help and support of all groups," and cited reports of discrimination: The Executive order (United States), executive order had also been demanded by civil rights activists A.

Jim Crow Laws
The Jim Crow laws were state and local laws enforcing racial segregation in the Southern United States. Other areas of the United States were affected by formal and informal policies of segregation as well, but many states outside the South had adopted laws, beginning in the late 19th century, banning discrimination in public accommodations and voting. Southern laws were enacted in the late 19th and early 20th centuries by white Southern Democrat-dominated state legislatures to disenfranchise and remove political and economic gains made by African Americans during the Reconstruction era. Jim Crow laws were enforced until 1965. In practice, Jim Crow laws mandated racial segregation in all public facilities in the states of the former Confederate States of America and in some others, beginning in the 1870s. Jim Crow laws were upheld in 1896 in the case of ''Plessy vs. Ferguson'', in which the Supreme Court laid out its "separate but equal" legal doctrine concerning faciliti ...

Great Depression In The United States
In the United States, the Great Depression began with the Wall Street Crash of October 1929 and then spread worldwide. The nadir came in 1931–1933, and recovery came in 1940. The stock market crash marked the beginning of a decade of high unemployment, poverty, low profits, deflation, plunging farm incomes, and lost opportunities for economic growth as well as for personal advancement. Altogether, there was a general loss of confidence in the economic future. The usual explanations include numerous factors, especially high consumer debt, ill-regulated markets that permitted overoptimistic loans by banks and investors, and the lack of high-growth new industries. These all interacted to create a downward economic spiral of reduced spending, falling confidence and lowered production. Industries that suffered the most included construction, shipping, mining, logging, and agriculture. Also hard hit was the manufacturing of durable goods like automobiles and appliances, whose purc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Farmville, Virginia
Farmville is a town in Prince Edward and Cumberland counties in the U.S. state of Virginia. The population was 8,216 at the 2010 census. It is the county seat of Prince Edward County. Farmville developed near the headwaters of the Appomattox River in central Virginia; the waterway was long its main transportation access to other markets. In the 19th century, a railroad was constructed here. Since the late 20th century, the former railway has been converted to the High Bridge Trail State Park, a more than rail trail park. US 15, VA 45 and US 460 now intersect at Farmville. The town is the home of Longwood University and is the town nearest to Hampden–Sydney College.
