Eleanor () is a feminine given name, originally from an Old French adaptation of the Old Provençal name ''Aliénor''. It is the name of a number of women of royalty and nobility in western Europe during the High Middle Ages. The name was introduced to England by Eleanor of Aquitaine, who came to marry King Henry II. It was also borne by Eleanor of Provence, who became Queen consort of England as the wife of King Henry III, and Eleanor of Castile, wife of Edward I. The name was popular in the United States in the 1910s and 1920s, peaking at rank 25 in 1920. It declined below 600 by the 1970s, again rose to rank 32 in the 2010s.

Philadelphia Naval Yard
The Philadelphia Naval Shipyard was an important naval shipyard of the United States for almost two centuries. Philadelphia's original navy yard, begun in 1776 on Front Street and Federal Street in what is now the Pennsport section of the city, was the first naval shipyard of the United States. It was replaced by a new, much larger yard developed around facilities begun in 1871 on League Island, at the confluence of the Delaware and Schuylkill rivers. The Navy Yard expansion stimulated the development over time of residential and businesses in South Philadelphia, where many shipyard workers lived. During World War II, some 40,000 workers operated on shifts around the clock to produce and repair ships at the yard for the war effort. The United States Navy ended most of its activities there in the 1990s, closing its base after recommendations by the Base Realignment and Closure commission. In 2000, the Philadelphia Industrial Development Corporation, on behalf of the city of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Astronomical League
The Astronomical League is an umbrella organization of amateur astronomy societies. Currently their membership consists of over 280 organizations across the United States, along with a number of Members-at-Large, Patrons, and Supporting members. The mission of the Astronomical League is to promote the science of astronomy by (1) fostering astronomical education; (2) providing incentives for astronomical observation and research; and (3) assisting communication among amateur astronomical societies. The Astronomical League provides a number of observing awards to members locating and describing certain specified astronomical objects or events, and produces a periodical publication, ''The Reflector''. History The beginning of the Astronomical League dates back to 1939 when members of eleven amateur astronomical societies met at the American Museum of Natural History in New York City. Similar meetings followed in Pittsburgh, 1940, Washington D.C., 1941, and Detroit, 1946. At the l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
David Rittenhouse Laboratory
The David Rittenhouse Laboratory (DRL) is an academic and research building at the University of Pennsylvania in Philadelphia, Pennsylvania, USA. The building is named for David Rittenhouse, a notable American astronomer and Penn professor of the 18th century and the president of the American Philosophical Society. DRL is the home of two departments of the University of Pennsylvania: the Physics and Astronomy Department and the Mathematics Department. Many other disciplines also hold classes in the building due to its ample lecture space. Because of this, the building is one of the most heavily used at the university. There is also an observatory on the roof that is accessible to astronomy students. The three-story portion of the building was constructed in 1954. The four-story addition was built in 1967. Partial funding for the building came from the General Authority of Pennsylvania, which has a seal displayed on the first floor of the building. The architect for the original ...

Sputnik
Sputnik 1 (; see § Etymology) was the first artificial Earth satellite. It was launched into an elliptical low Earth orbit by the Soviet Union on 4 October 1957 as part of the Soviet space program. It sent a radio signal back to Earth for three weeks before its three silver-zinc batteries ran out, and continued in orbit for three months until aerodynamic drag caused it to fall back into the atmosphere on 4 January 1958. It was a polished metal sphere in diameter with four external radio antennas to broadcast radio pulses. Its radio signal was easily detectable by amateur radio operators, and the 65° orbital inclination made its flight path cover virtually the entire inhabited Earth. The satellite's unanticipated success precipitated the American Sputnik crisis and triggered the Space Race, part of the Cold War. The launch was the beginning of a new era of political, military, technological and scientific developments. The word ''sputnik'' is Russian for ''satellite'' wh ...

Chemistry
Chemistry is the scientific study of the properties and behavior of matter. It is a natural science that covers the elements that make up matter to the compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances. Chemistry also addresses the nature of chemical bonds in chemical compounds. In the scope of its subject, chemistry occupies an intermediate position between physics and biology. It is sometimes called the central science because it provides a foundation for understanding both basic and applied scientific disciplines at a fundamental level. For example, chemistry explains aspects of plant growth ( botany), the formation of igneous rocks ( geology), how atmospheric ozone is formed and how environmental pollutants are degraded ( ecology), the properties of the soil on the moon ( cosmochemistry), how medications work (pharmacology), and how to collect DNA ...

Nutrition
Nutrition is the biochemical and physiological process by which an organism uses food to support its life. It provides organisms with nutrients, which can be metabolized to create energy and chemical structures. Failure to obtain sufficient nutrients causes malnutrition. Nutritional science is the study of nutrition, though it typically emphasizes human nutrition. The type of organism determines what nutrients it needs and how it obtains them. Organisms obtain nutrients by consuming organic matter, consuming inorganic matter, absorbing light, or some combination of these. Some can produce nutrients internally by consuming basic elements, while some must consume other organisms to obtain preexisting nutrients. All forms of life require carbon, energy, and water as well as various other molecules. Animals require complex nutrients such as carbohydrates, lipids, and proteins, obtaining them by consuming other organisms. Humans have developed agriculture and cooking to rep ...
