Possibilities were examined regarding a centralized computer system for all Navy training, minicomputers for remote classes, and shipboard computers for on-board training. The general state of the art and feasibility of CMI were reviewed, alternative computer languages and terminals studied, and criteria developed for selecting courses for CMI. Literature reviews, site visits, and a questionnaire survey were conducted. Results indicated that despite its high costs, CMI was necessary if a significant number of the more than 4000 Navy training courses were to become individualized and self-paced. It was concluded that the cost of implementing a large-scale centralized computer system for all training courses was prohibitive, but that the use of minicomputers for particular courses and for small, remote classes was feasible. It was also concluded that the use of shipboard computers for training was both desirable and technically feasible, but that this would require the acquisition of additional minicomputers for educational purposes since the existing shipboard equipment was both expensive to convert and already heavily used for other purposes. -

A Politico-Social History of Algolt (With a Chronology in the Form of a Log Book)
A Politico-Social History of Algolt (With a Chronology in the Form of a Log Book) R. w. BEMER Introduction This is an admittedly fragmentary chronicle of events in the develop ment of the algorithmic language ALGOL. Nevertheless, it seems perti nent, while we await the advent of a technical and conceptual history, to outline the matrix of forces which shaped that history in a political and social sense. Perhaps the author's role is only that of recorder of visible events, rather than the complex interplay of ideas which have made ALGOL the force it is in the computational world. It is true, as Professor Ershov stated in his review of a draft of the present work, that "the reading of this history, rich in curious details, nevertheless does not enable the beginner to understand why ALGOL, with a history that would seem more disappointing than triumphant, changed the face of current programming". I can only state that the time scale and my own lesser competence do not allow the tracing of conceptual development in requisite detail. Books are sure to follow in this area, particularly one by Knuth. A further defect in the present work is the relatively lesser availability of European input to the log, although I could claim better access than many in the U.S.A. This is regrettable in view of the relatively stronger support given to ALGOL in Europe. Perhaps this calmer acceptance had the effect of reducing the number of significant entries for a log such as this. Following a brief view of the pattern of events come the entries of the chronology, or log, numbered for reference in the text. -

Japanese Abacus Also Known As Soroban Has Been Made Available in India Thanks to Some Leading Players Like Virtual Academics
Japanese abacus also known as soroban has been made available in India thanks to some leading players like Virtual Academics who have proved their credibility a nd perfection in teaching abacus as a tool to make math a fun subject. Japanese abacus is considered as one of the oldest and accurate abacus of all time. Soroban was modified into the modern configuration. It is made from wood, and ha s five-bead in each column, one-bead in the upper deck and four-bead in the lowe r deck. The Soroban helps to perform mainly addition, subtraction, multiplicatio n and division. The Soroban was one of the necessary calculation tools before the electric calcu lator was widely used in Japan. Yet, the Soroban has been an excellent education al tool for children to understand and recognize numbers since its introduction. In addition, practicing Soroban gives you more opportunity to develop your ment al calculation ability. After mastering the Soroban, you will need no calculator with you because you are capable of calculating numbers by visualizing Soroban beads. Even though the structure has been adapted from chinese abacus, there are some d ifferences like there are 5 beads in one rod instead of 6 which is similar to gr eek abacus. Another unique feature that sets the soroban apart from its Chinese cousin is a dot marking every third rod in a soroban. These are unit rods and an y one of them is designated to denote the last digit of the whole number part of the calculation answer. Any number that is represented on rods to the right of this designated rod is part of the decimal part of the answer, unless the number is part of a division or multiplication calculation. -

Nonus: the Nine Bead Abacus, Its Theory and Derivation
Nonus: The Nine Bead Abacus, its Theory and Derivation By J.W. VanCleave I. Introduction It may come as some surprise to find that work is still being done with that ancient calculating device, the abacus. After all, we live in an era when the digital revolution is occurring, real time, right before our very eyes. The means and methods by which we work, play and communicate are changing at an unparalleled rate in human history. Yet, though the gap between the so-called underdeveloped nations and the “first world” nations is diminishing, many millions of people continue to use a version of the abacus in the exchange of everyday commerce, even in the 21st century. We have witnessed the recent phenomenon of the Japanese Soroban, its development, popularity and refinement during the post-WWII era into a device of high efficiency and methodology. This occurred in spite of Japan having been in the midst of a technological revolution, which, it would seem, would supplant the role of the bead-frame calculator to that of an antiquated, dusty museum piece. In this paper, we will cover a brief history of the abacus in both ancient and modern eras, and discuss the evolution of the device and refinement of its operation. Then, we will touch on the role that the bead-frame calculator has in modern America, in commerce, at home, and in the classroom. Finally, the author will present the results of research he has conducted on an updated, westernized nine-bead abacus, the Nonus, and its operation. We will also discuss the concept of the “minimal abacus”, and some practical examples. -

A Comparative Study of Korean Abacus Users' Perceptions And
A Comparative Study of Korean Abacus Users’ Perceptions and Explanations of Use: Including a Perspective on Stigler’s Mental Abacus Soomi Kim Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy under the Executive Committee of the Graduate School of Arts and Sciences COLUMBIA UNIVERSITY 2016 © 2015 Soomi Kim All Rights Reserved ABSTRACT A Comparative Study of Korean Abacus Users’ Perceptions and Explanations of Use: Including a Perspective on Stigler’s Mental Abacus Soomi Kim The purpose of this study was to determine the prevalence of using a “mental abacus” by adults whose mathematics education in Korea included extensive use of the actual abacus as both a teaching and computational aid. One hundred and sixty-nine Korean adults between the ages of 25 to 65 who had abacus training and its uses for a minimum of one year participated in the study. The study had two phases: a quantitative phase and a qualitative phase. The quantitative phase focused on the participants’ perceptions of their training and use of the abacus as well as an assessment of their basic arithmetic competencies. This served as a context for a more in- depth analysis of their perceptions of, and thinking about, the use of the abacus in arithmetic operations obtained in the qualitative phase. All participants were asked and then answered a total of 6 questions regarding basic background information about their abacus training as well as their current use of the abacus for arithmetic computations in order to examine the extent of Korean abacus uses. The questionnaires included an assessment of participants’ arithmetic computation skills. -
Wirth Transcript Final
A. M. Turing Award Oral History Interview with Niklaus Wirth by Elena Trichina ETH, Zürich, Switzerland March 13, 2018 Trichina: My name is Elena Trichina. It is my honor to interview Professor Niklaus Wirth for the Turing Award Winners Project of the Association for Computing Machinery, the ACM. The Turing Award, sometimes referred to as “the Nobel Prize of computing,” is given annually for major contributions of lasting importance in computing. Professor Wirth received his award in 1984 in recognition of his outstanding work in developing a sequence of programming languages – Euler, Algol-W, Pascal, Modula. The hallmarks of Wirth’s languages are their simplicity, economy of design, and high-level engineering. We will talk about it and many other things later today in the interview that takes place on the 13th of March, 2018, in the Swiss Federal Institute of Technology. So we start. Ready? Guten Tag, Niklaus. Gruetzi. Wirth: Добрый ден, Елена Василевна Здравствуи [Good morning, Elena. Hello. – ed.] Trichina: Well, although your command of Russian is sufficient, my command of Swiss German is a little bit rudimentary. Shall we continue in one of the languages where we both feel comfortable? What would it be? French? English? Wirth: Oh, I think English is better for me. Yes, yes. Trichina: Okay. It’s probably better for the audience. [laughs] Wirth: Okay. True. Trichina: Okay. We continue in English. Here in front of me there is a list of the most important days in your life. You were born in February 1934 in Winterthur, which is a sort of middle-size industrial town in Switzerland.
