Charles Bruce Stephenson
Charles Bruce Stephenson (February 9, 1929 – December 3, 2001) was an American astronomer. He was born on a ranch in Little Rock, Arkansas, the only son of Chauncey Elvira Stephenson and Ona Richards. During his youth he made a telescope and was a winner of the Bausch & Lomb Science Award while in High School. He attended Little Rock Junior College, then transferred to the University of Chicago. After being awarded a B.S. in mathematics in 1949, he went on to study astronomy in graduate school, attaining a M.S. in 1951. From 1951 until 1953, he served as an astronomy research assistant at Dearborn Observatory. While a student at Northwestern, he met his future wife, Elizabeth Strong—the couple were married in 1952. In 1953 he joined the military in the U.S. Army Map Service Lunar Occultation Program, serving until 1955 whereupon he returned to the study of astronomy at the University of California, Berkeley. As a doctoral student, he was awarded the '' Dorothy Klumpke Robert ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

University Of California, Berkeley Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university ...

People From Little Rock, Arkansas
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 per ...

Hydrogen Alpha
H-alpha (Hα) is a specific deep-red visible spectral line in the Balmer series with a wavelength of 656.28 nm in air and 656.46 nm in vacuum; it occurs when a hydrogen electron falls from its third to second lowest energy level. H-alpha light is the brightest hydrogen line in the visible spectral range. It is important to astronomers as it is emitted by many emission nebulae and can be used to observe features in the Sun's atmosphere, including solar prominences and the chromosphere. Balmer series According to the Bohr model of the atom, electrons exist in quantized energy levels surrounding the atom's nucleus. These energy levels are described by the principal quantum number ''n'' = 1, 2, 3, ... . Electrons may only exist in these states, and may only transit between these states. The set of transitions from ''n'' ≥ 3 to ''n'' = 2 is called the Balmer series and its members are named sequentially by Greek letters: *''n'' = 3 to ''n'' = 2 is called Balmer-alpha or ...

Warner & Swasey Observatory
The Warner and Swasey Observatory is the astronomical observatory of Case Western Reserve University. Named after Worcester R. Warner and Ambrose Swasey, who built it at the beginning of the 20th century, it was initially located on Taylor Road in East Cleveland, Ohio, USA. The observatory, which at that time housed a refractor, was donated in 1919 to the Case School of Applied Science. The newer Burrell Schmidt telescope was built in 1939. Due to rising light pollution in Cleveland, a new station in Geauga County's Montville Township was established in 1950s. Named after Jason John Nassau, the station initially housed the Burrell telescope, which was later moved to Kitt Peak National Observatory. Instead of Burrell the station was equipped with the 36-inch robotic telescope. In 2008 Nassau Station was sold to the Geauga Park District and subsequently incorporated into its Observatory Park. The observatory currently operates the old 9.5-inch refractor (now known as the r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
