Angeline Stickney Hall
Chloe Angeline Stickney Hall (November 1, 1830 – July 3, 1892) was an American mathematician and suffragist who was the wife of astronomer Asaph Hall. Stickney Hall was an active participant in her husband's search for the moons of Mars, performing mathematical calculations on the data he collected. Early life Angeline Stickney was born to Theophilus Stickney and Electa Cook on November 1, 1830. In 1847 she took three terms of study funded by her cousin, Harriette Downs, at Rodman Union Seminary. Stickney was able to attend New-York Central College with help from her sister Ruth and by teaching at the college. She majored in science and mathematics, doing coursework in calculus and mathematical astronomy, and graduated with the college's first class, in 1855. New-York Central College was a progressive school where students of modest means, including women and free African Americans, could earn a college degree. It was here that she became passionate about the causes of women's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Andover, Massachusetts
North Andover is an affluent town in Essex County, Massachusetts, United States. At the 2020 census the population was 30,915. History Native Americans inhabited what is now northeastern Massachusetts for thousands of years prior to European colonization of the Americas. At the time of European arrival, Massachusett and Naumkeag people inhabited the area south of the Merrimack River and Pennacooks inhabited the area to the north. The Massachusett referred to the area that would later become North Andover as ''Cochichawick''. The lands south of the Merrimack River around Lake Cochichewick and the Shawsheen River were set aside by the Massachusetts General Court in 1634 for the purpose of creating an inland plantation. The Cochichewick Plantation, as it was called, was purchased on May 6, 1646 when Reverend John Woodbridge, who had settled the land for the English, paid Massachusett sachem Cutshamekin six pounds and a coat for the lands. The plantation was then incorporated as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phobos (moon)
Phobos (; astronomical naming conventions, systematic designation: ) is the innermost and larger of the two moons of Mars, natural satellites of Mars, the other being Deimos (moon), Deimos. The two moons were discovered in 1877 by American astronomer Asaph Hall. It is named after Phobos (mythology), Phobos, the Greek mythology, Greek god of fear and panic, who is the son of Ares (Mars) and twin brother of Deimos (deity), Deimos. Phobos is a small, irregularly shaped object with a mean radius of . Phobos orbits from the Martian surface, closer to its Primary (astronomy), primary body than any other known Natural satellite, planetary moon. It is so close that it orbits Mars much faster than Mars rotates, and completes an orbit in just 7 hours and 39 minutes. As a result, from the surface of Mars it appears to rise in the west, move across the sky in 4 hours and 15 minutes or less, and set in the east, twice each Mars sol, Martian day. Phobos is one of the least reflective bodie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People Associated With Astronomy
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of ...

Stickney Crater
Stickney is the largest crater on Phobos, which is a satellite of Mars. It is in diameter, taking up a substantial proportion of the moon's surface. Naming The crater is named after mathematician Chloe Angeline Stickney Hall, the wife of Phobos' discoverer Asaph Hall whose support was credited by her husband as critical for his discovery of the moon. The crater was named in 1973, based on ''Mariner 9'' images, by an IAU nomenclature committee chaired by Carl Sagan.. Formation There are two models for the age of Stickney, based on the differing possible dates at which Phobos began to orbit around Mars. If Phobos has been orbiting for 4.3 Ga (billion years) then Stickney formed 4.2 Ga ago, but if it has only been orbiting for 3.5 Ga then the crater is 2.6 Ga old. The impact created a large amount of ejecta which escaped Phobos' gravity and ended up in orbit around Mars for a period not exceeding 1000 years, some of this material then crashed back onto Phobos and created second ...

Gallaudet University
Gallaudet University ( ) is a private federally chartered research university in Washington, D.C. for the education of the deaf and hard of hearing. It was founded in 1864 as a grammar school for both deaf and blind children. It was the first school for the advanced education of the deaf and hard of hearing in the world and remains the only higher education institution in which all programs and services are specifically designed to accommodate deaf and hard of hearing students. Hearing students are admitted to the graduate school and a small number are also admitted as undergraduates each year. The university was named after Thomas Hopkins Gallaudet, a notable figure in the advancement of deaf education. Gallaudet University is officially bilingual, with American Sign Language (ASL) and written English used for instruction and by the college community. Although there are no specific ASL proficiency requirements for undergraduate admission, many graduate programs require varying ...

Detroit Observatory
The Detroit Observatory is located on the corner of Observatory and Ann streets in Ann Arbor, Michigan. It was built in 1854, and was the first scientific research facility at the University of Michigan and one of the oldest observatories of its type in the nation. It was designated a Michigan State Historic Site in 1958 and placed on the National Register of Historic Places in 1973. Building the Observatory Henry Philip Tappan was inaugurated as the president of the University of Michigan in December 1852, and in his inaugural speech appealed to the citizens of Michigan to support research and laboratory space at the University. Immediately afterward, Tappan was approached by Detroit businessman (and former Michigan Attorney General) Henry N. Walker, who offered assistance. Tappan suggested raising funds for an observatory, and Walker agreed to spearhead a fundraising drive. Walker soon raised over $7000 from the citizens of Detroit, a figure that increased to a total of $18,76 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Unitarianism
Unitarianism (from Latin ''unitas'' "unity, oneness", from ''unus'' "one") is a nontrinitarian branch of Christian theology. Most other branches of Christianity and the major Churches accept the doctrine of the Trinity which states that there is one God who exists in three coequal, coeternal, consubstantial divine persons: God the Father, God the Son (Jesus in Christianity, Jesus Christ) and Holy Spirit in Christianity, God the Holy Spirit. Unitarian Christians believe that Jesus was Divine_inspiration, inspired by God in his moral teachings and that he is a Redeemer (Christianity), savior, but not God himself. Unitarianism was established in order to restore "History of Christianity#Early Christianity (c. 31/33–324), primitive Christianity before [what Unitarians saw as] later corruptions setting in"; Unitarians generally reject the doctrine of original sin. The churchmanship of Unitarianism may include liberal denominations or Unitarian Christian denominations that are mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
