Richard V. Andree
Richard Vernon Andree (16 December 1919 – 8 May 1987) was an American mathematician and computer scientist. Andree taught at the University of Oklahoma for 37 years, and served as a professor emeritus there until his death. He and his wife, Josephine, founded the Mu Alpha Theta mathematics honor society. Andree wrote a book on abstract algebra entitled ''Selections From Modern Abstract Algebra'' which was first published in 1958. He also wrote and published at his own expense numerous puzzle books and enjoyed cryptography. Andree and his students developed the ALPS programming language for the Bendix G-15 computer. For several years in the late 1960s and thru the 1970s, Andree ran a summer school for high school teachers in Oklahoma to expose them to computers. Teachers would come from around the state and take short courses in programming in FORTRAN or BASIC. He also held evening and night computer study labs for local business owners wanting an exposure to computer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Science
Computer science is the study of computation, information, and automation. Computer science spans Theoretical computer science, theoretical disciplines (such as algorithms, theory of computation, and information theory) to Applied science, applied disciplines (including the design and implementation of Computer architecture, hardware and Software engineering, software). Algorithms and data structures are central to computer science. The theory of computation concerns abstract models of computation and general classes of computational problem, problems that can be solved using them. The fields of cryptography and computer security involve studying the means for secure communication and preventing security vulnerabilities. Computer graphics (computer science), Computer graphics and computational geometry address the generation of images. Programming language theory considers different ways to describe computational processes, and database theory concerns the management of re ...

Writers From Michigan
A writer is a person who uses written words in different writing styles, genres and techniques to communicate ideas, to inspire feelings and emotions, or to entertain. Writers may develop different forms of writing such as novels, short stories, monographs, travelogues, plays, screenplays, teleplays, songs, and essays as well as reports, educational material, and news articles that may be of interest to the general public. Writers' works are nowadays published across a wide range of media. Skilled writers who are able to use language to express ideas well, often contribute significantly to the cultural content of a society. The term "writer" is also used elsewhere in the arts and music, such as songwriter or a screenwriter, but also a stand-alone "writer" typically refers to the creation of written language. Some writers work from an oral tradition. Writers can produce material across a number of genres, fictional or non-fictional. Other writers use multiple media such a ...

Pi Mu Epsilon
Pi Mu Epsilon ( or PME) is the U.S. honorary national mathematics society. The society currently has chapters at 371 institutions across the U.S. History Pi Mu Epsilon was founded at Syracuse University on , by Professor Edward Drake Roe, Jr. Pi Mu Epsilon is dedicated to the promotion of mathematics and recognition of students who successfully pursue mathematical understanding. To promote mathematics, the National Pi Mu Epsilon Council co-sponsors an annual conference in conjunction with the Mathematical Association of America. Eileen Poiani was the first woman to be elected as president of Pi Mu Epsilon, serving as president for 1987–1990. Symbols Pi Mu Epsilon's motto is ' or "To promote scholarship and mathematics". Its colors are violet, gold and lavender. Its flower is the Violet. Activities The society also publishes a semi-annual journal, the ''Pi Mu Epsilon Journal'', which both presents research papers particularly focusing on student authored papers, as well as ...

Bendix G-15
The Bendix G-15 is a computer introduced in 1956 by the Bendix Corporation, Computer Division, Los Angeles, California. It is about and weighs about . The G-15 has a drum memory of 2,160 29-bit words, along with 20 words used for special purposes and rapid-access storage. The base system, without peripherals, cost $49,500. A working model cost around $60,000 (). It could also be rented for $1,485 per month. It was meant for scientific and industrial markets. The series was gradually discontinued when Control Data Corporation took over the Bendix computer division in 1963. The chief designer of the G-15 was Harry Huskey, who had worked with Alan Turing on the Automatic Computing Engine (ACE) in the United Kingdom and on the SWAC (computer), Standards Western Automatic Computer (SWAC) in the 1950s. He made most of the design while working as a professor at University of California, Berkeley (where his graduate students included Niklaus Wirth), and other universities. David C. Evan ...

Cryptography
Cryptography, or cryptology (from "hidden, secret"; and ''graphein'', "to write", or ''-logy, -logia'', "study", respectively), is the practice and study of techniques for secure communication in the presence of Adversary (cryptography), adversarial behavior. More generally, cryptography is about constructing and analyzing Communication protocol, protocols that prevent third parties or the public from reading private messages. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, information security, electrical engineering, digital signal processing, physics, and others. Core concepts related to information security (confidentiality, data confidentiality, data integrity, authentication, and non-repudiation) are also central to cryptography. Practical applications of cryptography include electronic commerce, Smart card#EMV, chip-based payment cards, digital currencies, password, computer passwords, and military communications. ...

Algebra
Algebra is a branch of mathematics that deals with abstract systems, known as algebraic structures, and the manipulation of expressions within those systems. It is a generalization of arithmetic that introduces variables and algebraic operations other than the standard arithmetic operations, such as addition and multiplication. Elementary algebra is the main form of algebra taught in schools. It examines mathematical statements using variables for unspecified values and seeks to determine for which values the statements are true. To do so, it uses different methods of transforming equations to isolate variables. Linear algebra is a closely related field that investigates linear equations and combinations of them called '' systems of linear equations''. It provides methods to find the values that solve all equations in the system at the same time, and to study the set of these solutions. Abstract algebra studies algebraic structures, which consist of a set of mathemati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
