- أرنولد أفرايم روس (بالإنجليزية: Arnold Ephraim Ross)، هو عالم رياضياتي أمريكي، (ولد في 24 أغسطس 1906، توفي في 25 سبتمبر 2002). (ar)
- Arnold Ephraim Ross (August 24, 1906 – September 25, 2002) was a mathematician and educator who founded the Ross Mathematics Program, a number theory summer program for gifted high school students. He was born in Chicago, but spent his youth in Odessa, Ukraine, where he studied with Samuil Shatunovsky. Ross returned to Chicago and enrolled in University of Chicago graduate coursework under E. H. Moore, despite his lack of formal academic training. He received his Ph.D. and married his wife, Bee, in 1931. Ross taught at several institutions including St. Louis University before becoming chair of University of Notre Dame's mathematics department in 1946. He started a teacher training program in mathematics that evolved into the Ross Mathematics Program in 1957 with the addition of high school students. The program moved with him to Ohio State University when he became their department chair in 1963. Though forced to retire in 1976, Ross ran the summer program until 2000. He had worked with over 2,000 students during more than forty summers. The program is known as Ross's most significant work. Its attendees have since continued on to prominent research positions across the sciences. His program inspired several offshoots and was recognized by mathematicians as highly influential. Ross has received an honorary doctorate and several professional association awards for his instruction and service. (en)
- Arnold Ephraim Ross (* als Arnold Ephraim Chaimovich am 24. August 1906 in Chicago; † 25. September 2002 ebenda) war ein US-amerikanischer Mathematiker und Mathematikpädagoge. Ross war der Sohn ukrainisch-jüdischer Einwanderer und wurde 1906 in Chicago geboren, zog aber 1909 mit seiner Mutter nach Odessa. Dort war er ein Schüler von Samuil Ossipowitsch Schatunowski und besuchte auch die Universität. Die Zeit seiner Jugend war geprägt durch die politischen Unruhen und Hunger. 1922 kehrte er in die USA zurück und wurde trotz fehlender formaler Qualifikation (er musste auch Englisch-Stunden nehmen) von E. H. Moore an der Universität Chicago als Student angenommen. Moores pädagogische Methoden beeinflussten Ross stark. 1931 wurde er bei Leonard Dickson in Zahlentheorie promoviert (On Representation of Integers by Indefinite Ternary Quadratic Forms). Als Post-Doktorand war er bei Eric Temple Bell am Caltech. Danach war er während der Großen Depression Lehrer an einer experimentellen Schule (People's Junior College) in Chicago. 1931 heiratete er Bertha (Bee) Horecker. Nach ihrem Tod 1983 heiratete er 1990 Madeleine Green. 1935 wurde er Assistant Professor an der St. Louis University. Im Zweiten Weltkrieg arbeitete er für die US Navy. 1946 wurde er Leiter der Mathematikabteilung der University of Notre Dame. In dieser Zeit holte er unter anderem Paul Erdös an die Universität. 1963 wurde er Professor und Leiter der Mathematikabteilung an der Ohio State University (OSU). 1976 wurde er emeritiert. Bekannt ist er für ein Lehrerfortbildungsprogramm und Sommerschule in Zahlentheorie für Schüler, die er 1957 bis 2000 betreute, als er einen Schlaganfall erlitt. Ross half auch in den 1970er Jahren ähnliche Programme in der Bundesrepublik Deutschland, Indien und Australien zu etablieren und inspirierte ähnliche Programme an anderen US-amerikanischen und kanadischen Universitäten. 1984 wurde er Ehrendoktor der Denison University und 1985 erhielt er den Distinguished Service Award der Mathematical Association of America (MAA) und 1998 die AMS Citation for Public Service. 1988 wurde er Fellow der American Association for the Advancement of Science. 1974 erhielt er den Distinguished Teaching Award der OSU. 1993 stiftete die American Mathematical Society (AMS) die Arnold Ross Lecture.

Em 1931 casou com Bertha (Bee) Horecker. Em 1935 foi professor assistente na . Na Segunda Guerra Mundial trabalhou para a Marinha dos Estados Unidos. Em 1946 foi coordenador do Departamento de Matemática da Universidade de Notre Dame.

Aposentou-se em 1976. (pt)

- This emphasis on computation alone too often produces students who have never practiced thinking for themselves, who have never asked why things work the way they do, who are not prepared to lead the way to future scientific innovation. It is precisely this independence of thought and questioning attitude that the Ross Program strives to nurture. (en)
