American Association Of State Colleges And Universities
The American Association of State Colleges and Universities (AASCU) is an organization of state-supported colleges and universities that offer degree programs leading to bachelor's, master's or doctoral degrees. AASCU grew out of the Association of Teacher Education Institutions that had been organized in 1951 to serve public comprehensive institutions. Most of the original member institutions began as single-purpose institutions, most commonly normal school A normal school or normal college is an institution created to train teachers by educating them in the norms of pedagogy and curriculum. In the 19th century in the United States, instruction in normal schools was at the high school level, turni ...s. Purpose The AASCU has a four-fold purpose: *To promote appreciation and support for public higher education and the distinctive contributions of our member colleges and universities; *To analyze public policy, and to advocate for member institutions and the students they s ...

Howard University Alumni
Howard is an English-language given name originating from Old French Huard (or Houard) from a Germanic source similar to Old High German ''*Hugihard'' "heart-brave", or ''*Hoh-ward'', literally "high defender; chief guardian". It is also probably in some cases a confusion with the Old Norse cognate ''Haward'' (''Hávarðr''), which means "high guard" and as a surname also with the unrelated Hayward. In some rare cases it is from the Old English ''eowu hierde'' "ewe herd". In Anglo-Norman the French digram ''-ou-'' was often rendered as ''-ow-'' such as ''tour'' → ''tower'', ''flour'' (western variant form of ''fleur'') → ''flower'', etc. (with svarabakhti). A diminutive is "Howie" and its shortened form is "Ward" (most common in the 19th century). Between 1900 and 1960, Howard ranked in the U.S. Top 200; between 1960 and 1990, it ranked in the U.S. Top 400; between 1990 and 2004, it ranked in the U.S. Top 600. People with the given name Howard or its variants include: Given ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientists From Philadelphia
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''

African-American Chemists
African Americans (also referred to as Black Americans and Afro-Americans) are an ethnic group consisting of Americans with partial or total ancestry from sub-Saharan Africa. The term "African American" generally denotes descendants of enslaved Africans who are from the United States. While some Black immigrants or their children may also come to identify as African-American, the majority of first generation immigrants do not, preferring to identify with their nation of origin. African Americans constitute the second largest racial group in the U.S. after White Americans, as well as the third largest ethnic group after Hispanic and Latino Americans. Most African Americans are descendants of enslaved people within the boundaries of the present United States. On average, African Americans are of West/ Central African with some European descent; some also have Native American and other ancestry. According to U.S. Census Bureau data, African immigrants generally do not self- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
African-American Scientists And Technicians On The Manhattan Project
African-American scientists and technicians on the Manhattan Project held a small number of positions among the several hundred scientists and technicians involved. Nonetheless, African-American men and women made important contributions to the Manhattan Project during World War II. At the time, their work was shrouded in secrecy, intentionally compartmentalized and decontextualized so that almost no one knew the purpose or intended use of what they were doing. As government documents have been declassified and historians have examined archives and collected oral histories, the work of people like physical chemist William Jacob Knox Jr., chemist Lloyd Quarterman, physicist Carolyn Parker, physicist and mass spectrometrist Robert Johnson Omohundro, and physicist and mathematician Jesse Ernest Wilkins Jr. is being recognized. They contributed to the theoretical understanding of nuclear physics (Wilkins), the extraction and processing of the fissionable uranium isotope, Uranium ...

Silver Spring, Maryland
Silver Spring is a census-designated place (CDP) in southeastern Montgomery County, Maryland, United States, near Washington, D.C. Although officially unincorporated, in practice it is an edge city, with a population of 81,015 at the 2020 census, making it the fifth-most populous place in Maryland after Baltimore, Columbia, Germantown, and Waldorf. Downtown, next to the northern tip of Washington, D.C., is the oldest and most urbanized part of the community, surrounded by several inner suburban residential neighborhoods inside the Capital Beltway. Many mixed-use developments combining retail, residential, and office space have been built since 2004. Silver Spring takes its name from a mica-flecked spring discovered there in 1840 by Francis Preston Blair, who subsequently bought much of the surrounding land. Acorn Park, south of downtown, is believed to be the site of the original spring. Geography As an unincorporated CDP, Silver Spring's boundaries are not consistently de ...
