Joseph Dennis (mathematician)
Joseph James Dennis (11 April 1905 in Gainesville, Florida – April 1977)Joseph Dennis in the U.S., Social Security Death Index, 1935-2014 was an African-American mathematician. He served as the chairman of the Clark College mathematics department from 1930 to 1974. Dennis gained his B.A. from Clark College in 1929, and his M.A. from Northwestern University in 1935. He earned his Ph.D. at Northwestern University in 1944. This is the same year as two other African-American men earned a Ph.D in mathematics, Wade Ellis Sr. and Warren Hill Brothers (both from the University of North Western University). His thesis was "Some Points in the Theory of Positive Definite J-Fractions" (related to continued fraction In mathematics, a continued fraction is an expression obtained through an iterative process of representing a number as the sum of its integer part and the reciprocal of another number, then writing this other number as the sum of its integ ...s), supervised by H.

Gainesville, Florida
Gainesville is the county seat of Alachua County, Florida, and the largest city in North Central Florida, with a population of 141,085 in 2020. It is the principal city of the Gainesville metropolitan area, which had a population of 339,247 in 2020. Gainesville is home to the University of Florida, the fourth-largest public university campus by enrollment in the United States as of the 2021–2022 academic year. History There is archeological evidence, from about 12,000 years ago, of the presence of Paleo Indians in the Gainesville area, although it is not known if there were any permanent settlements. A Deptford culture campsite existed in Gainesville and was estimated to have been used between 500 BCE and 100 CE. The Deptford people moved south into Paynes Prairie and Orange Lake during the first century and evolved into the Cades Pond culture. The Deptford people who remained in the Gainesville area were displaced by migrants from southern Georgia sometime in the seven ...

Clark College (Washington)
Clark College is a public community college in Vancouver, Washington. With 11,500 students, Clark College is the largest institution of higher education in southwest Washington. Founded in 1933 as a private two-year junior college, Clark College received its first accreditation in 1937 and has been accredited by the Northwest Commission on Colleges and Universities since 1948. It was incorporated into the statewide community college system in 1967. History Originally known as Vancouver Junior College, the college was located at the old Hidden House at 100 W 13th Street in downtown Vancouver from 1933 to 1937, moving several times within the city. The main campus was formerly part of the Vancouver Barracks, which extended from Fourth Plain to the Columbia River but were ceded by the U.S. Army to the city to become Central Park. The college first received state support in 1941, being supervised by the State Board of Education in 1946 with the Vancouver School Board serving as ...

Northwestern University
Northwestern University is a private research university in Evanston, Illinois. Founded in 1851, Northwestern is the oldest chartered university in Illinois and is ranked among the most prestigious academic institutions in the world. Chartered by the Illinois General Assembly in 1851, Northwestern was established to serve the former Northwest Territory. The university was initially affiliated with the Methodist Episcopal Church but later became non-sectarian. By 1900, the university was the third largest university in the United States. In 1896, Northwestern became a founding member of the Big Ten Conference, and joined the Association of American Universities as an early member in 1917. The university is composed of eleven undergraduate, graduate, and professional schools, which include the Kellogg School of Management, the Pritzker School of Law, the Feinberg School of Medicine, the Weinberg College of Arts and Sciences, the Bienen School of Music, the McCormic ...

Warren Hill Brothers
A warren is a network of wild rodent or lagomorph, typically rabbit burrows. Domestic warrens are artificial, enclosed establishment of animal husbandry dedicated to the raising of rabbits for meat and fur. The term evolved from the medieval Anglo-Norman concept of free warren, which had been, essentially, the equivalent of a hunting license for a given woodland. Architecture of the domestic warren The cunicularia of the monasteries may have more closely resembled hutches or pens, than the open enclosures with specialized structures which the domestic warren eventually became. Such an enclosure or ''close'' was called a ''cony-garth'', or sometimes ''conegar'', ''coneygree'' or "bury" (from "burrow"). Moat and pale To keep the rabbits from escaping, domestic warrens were usually provided with a fairly substantive moat, or ditch filled with water. Rabbits generally do not swim and avoid water. A '' pale'', or fence, was provided to exclude predators. Pillow mounds The most c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Continued Fraction
In mathematics, a continued fraction is an expression obtained through an iterative process of representing a number as the sum of its integer part and the reciprocal of another number, then writing this other number as the sum of its integer part and another reciprocal, and so on. In a finite continued fraction (or terminated continued fraction), the iteration/recursion is terminated after finitely many steps by using an integer in lieu of another continued fraction. In contrast, an infinite continued fraction is an infinite expression. In either case, all integers in the sequence, other than the first, must be positive. The integers a_i are called the coefficients or terms of the continued fraction. It is generally assumed that the numerator of all of the fractions is 1. If arbitrary values and/or functions are used in place of one or more of the numerators or the integers in the denominators, the resulting expression is a generalized continued fraction. When it is ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hubert Stanley Wall
Hubert Stanley Wall (December 2, 1902 – September 12, 1971) was an American mathematician who worked primarily in the field of continued fractions. He is also known as one of the leading proponents of the Moore method of teaching. Early life and education Wall was born in Rockwell City, Iowa on December 2, 1902. He received the Bachelor of Arts and Master of Arts degrees from Cornell College in Mount Vernon, Iowa in 1924. He received his Ph.D. degree from the University of Wisconsin (now University of Wisconsin–Madison) in 1927. He married Mary Kate Parker, a lawyer and Texas assistant Attorney General. Her specialty was election law. Career Upon receiving his Ph.D. Wall joined the faculty at Northwestern University and stayed until 1944 except for the academic year 1938–1939 when he was at the Institute for Advanced Study. He then went to the Illinois Institute of Technology for two years before moving in 1946 to the University of Texas where he spent the rest of hi ...

African Americans
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 Slavery in the United States, 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 Africa, West/Central Africa, Central African with some European descent; some also have Native Americans in the United States, Native American and othe ...
