New Haven
New Haven is a city of the U.S. state of Connecticut. It is located on New Haven Harbor on the northern shore of Long Island Sound. With a population of 135,081 as determined by the 2020 U.S. census, New Haven is the third largest city in Connecticut after Bridgeport and Stamford, the largest city in the South Central Connecticut Planning Region, and the principal municipality of Greater New Haven metropolitan area, which had a total population of 864,835 in 2020. New Haven was one of the first planned cities in the U.S. A year after its founding by English Puritans in 1638, eight streets were laid out in a four-by-four grid, creating the "Nine Square Plan". The central common block is the New Haven Green, a square at the center of Downtown New Haven. The Green is now a National Historic Landmark, and the "Nine Square Plan" is recognized by the American Planning Association as a National Planning Landmark. New Haven is the home of Yale University, New Haven's big ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alma Mater
Alma mater (; : almae matres) is an allegorical Latin phrase meaning "nourishing mother". It personifies a school that a person has attended or graduated from. The term is related to ''alumnus'', literally meaning 'nursling', which describes a school graduate. In its earliest usage, ''alma mater'' was an honorific title for various mother goddesses, especially Ceres or Cybele.''Shorter Oxford English Dictionary'', 3rd edition Later, in Catholicism, it became a title for Mary, mother of Jesus. By the early 17th century, the nursing mother became an allegory for universities. Used by many schools in Europe and North America, it has special association with the University of Bologna, whose motto ''Alma Mater Studiorum'' ("nurturing mother of studies") emphasizes its role in originating the modern university. Several university campuses in North America have artistic representations of ''alma mater'', depicted as a robed woman wearing a laurel wreath crown. Etymology Although ...

American Astronomical Society
The American Astronomical Society (AAS, sometimes spoken as "double-A-S") is an American society of professional astronomers and other interested individuals, headquartered in Washington, DC. The primary objective of the AAS is to promote the advancement of astronomy and closely related branches of science, while the secondary purpose includes enhancing astronomy education and providing a political voice for its members through lobbying and grassroots activities. Its current mission is to enhance and share humanity's scientific understanding of the universe as a diverse and inclusive astronomical community. History The society was founded in 1899 through the efforts of George Ellery Hale. The constitution of the group was written by Hale, George Comstock, Edward Morley, Simon Newcomb and Edward Charles Pickering. These men, plus four others, were the first Executive Council of the society; Newcomb was the first president. The initial membership was 114. The AAS name of the ...

Annie Jump Cannon
Annie Jump Cannon (; December 11, 1863 – April 13, 1941) was an American astronomer whose cataloging work was instrumental in the development of contemporary stellar classification. With Edward C. Pickering, she is credited with the creation of the Stellar classification, Harvard Classification Scheme, which was the first serious attempt to organize and classify stars based on their temperatures and spectral types. She was nearly deaf throughout her career after 1893, as a result of scarlet fever. She was a Suffragette, suffragist and a member of the National Woman's Party, National Women's Party. Personal life Cannon was born on December 11, 1863, in Dover, Delaware. She was the eldest of three daughters born to Wilson Cannon, a Delaware shipbuilder and state senator, and his second wife, Mary Jump. Cannon's mother was the first person to teach her the constellations and she encouraged her to follow her own interests, suggesting that she pursue studies in mathematics, chemistry ...

Carrie Chapman Catt
Carrie Chapman Catt (born Carrie Clinton Lane; January 9, 1859#Fowler, Fowler, p. 3 – March 9, 1947) was an American women's suffrage leader who campaigned for the Nineteenth Amendment to the United States Constitution, which gave U.S. women the right to vote in 1920. Catt served as president of the National American Woman Suffrage Association from 1900 to 1904 and 1915 to 1920. She founded the League of Women Voters in 1920 and the International Woman Suffrage Alliance in 1904,#Voris, Van Voris, pp. 59–63 which was later named International Alliance of Women. She "led an army of voteless women in 1919 to pressure Congress to pass the constitutional amendment giving them the right to vote and convinced state legislatures to ratify it in 1920". She "was one of the best-known women in the United States in the first half of the twentieth century and was on all lists of famous American women."#Voris, Van Voris, p. vii Early life Carrie Clinton Lane was born on January 9, 1859, ...

Women's Centennial Congress
The Women's Centennial Congress was organized by Carrie Chapman Catt and held at the Astor Hotel on November 25-27, 1940, to celebrate a century of female progress. History The date chosen was 100 years after the first World Anti-Slavery Convention in London in 1840. That convention had been a gathering of abolitionists from around the world. The organisers were surprised when women were sent as delegates and the initial reaction was to deny them entry. Women including the female delegates were only allowed in under sufferance and they were forbidden from speaking or voting. This event was, in time, the catalyst for later efforts in the suffrage movement, especially the Seneca Falls Convention. At the Women's Centennial Congress, 100 successful women, most notably Eleanor Roosevelt, were selected to represent female progress in numerous fields, John G. Reid, '' Viola Florence Barnes, 1885-1979: a historian's biography'', University of Toronto Press, 2005, page 97 although Catt ...

Ellen Dorrit Hoffleit
Ellen Dorrit Hoffleit (March 12, 1907 – April 9, 2007) was an American senior research astronomer at Yale University. She is best known for her work in variable stars, astrometry, spectroscopy, meteors, and the Bright Star Catalog. She is also known for her mentorship of many young women and generations of astronomers. Life Hoffleit's interest in astronomy began with the 1919 Perseid meteor shower that she saw with her mother. In 1928, she graduated cum laude with a B.A. in mathematics. She then went on to work for the Harvard College Observatory, searching for variable stars. In 1938, she was awarded a Ph.D. in astronomy from Radcliffe College and was subsequently hired, in 1948, as an astronomer at Harvard University. She remained at Harvard until 1956 when she moved to Yale University. She remained at Yale until retirement in 1975. At Yale she followed in the footsteps of Ida Barney, taking over her astrometric work, and of whom she later wrote "To know erwas a pleasure ...

Proper Motion
Proper motion is the astrometric measure of changes in the apparent places of stars or other celestial objects as they move relative to the center of mass of the Solar System. It is measured relative to the distant stars or a stable reference such as the International Celestial Reference Frame (ICRF). Patterns in proper motion reveal larger structures like stellar streams, the general rotation of the Milky Way disk, and the random motions of stars in the Galactic halo. The components for proper motion in the equatorial coordinate system (of a given epoch, often J2000.0) are given in the direction of right ascension (''μ''α) and of declination (''μ''δ). Their combined value is computed as the ''total proper motion'' (''μ''). It has dimensions of angle per time, typically arcseconds per year or milliarcseconds per year. Knowledge of the proper motion, distance, and radial velocity allows calculations of an object's motion from the Solar System's frame of reference an ...

Apparent Magnitude
Apparent magnitude () is a measure of the Irradiance, brightness of a star, astronomical object or other celestial objects like artificial satellites. Its value depends on its intrinsic luminosity, its distance, and any extinction (astronomy), extinction of the object's light caused by interstellar dust along the sightline, line of sight to the observer. Unless stated otherwise, the word ''magnitude'' in astronomy usually refers to a celestial object's apparent magnitude. The magnitude scale likely dates to before the ancient Ancient Greek astronomy#Astronomy in the Greco-Roman and Late Antique eras, Roman astronomer Ptolemy, Claudius Ptolemy, whose Star catalogue, star catalog popularized the system by listing stars from First-magnitude star, 1st magnitude (brightest) to 6th magnitude (dimmest). The modern scale was mathematically defined to closely match this historical system by Norman Robert Pogson, Norman Pogson in 1856. The scale is reverse logarithmic scale, logarithmic: ...

Star Catalogue
A star catalogue is an astronomical catalogue that lists stars. In astronomy, many stars are referred to simply by catalogue numbers. There are a great many different star catalogues which have been produced for different purposes over the years, and this article covers only some of the more frequently quoted ones. Star catalogues were compiled by many different ancient people, including the Babylonians, Greeks, Chinese, Persians, and Arabs. They were sometimes accompanied by a star chart for illustration. Most modern catalogues are available in electronic format and can be freely downloaded from space agencies' data centres. The largest is being compiled from the spacecraft '' Gaia'' and thus far has over a billion stars. Completeness and accuracy are described by the faintest limiting magnitude V (largest number) and the accuracy of the positions. Historical catalogues Ancient Near East From their existing records, it is known that the ancient Egyptians recorded th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
