THE INTELLECTUAL ORIGINS of the Mcculloch
JHBS—WILEY RIGHT BATCH Top of ID Journal of the History of the Behavioral Sciences, Vol. 38(1), 3–25 Winter 2002 ᭧ 2002 John Wiley & Sons, Inc. (PHYSIO)LOGICAL CIRCUITS: THE INTELLECTUAL ORIGINS OF THE Base of 1st McCULLOCH–PITTS NEURAL NETWORKS line of ART TARA H. ABRAHAM This article examines the intellectual and institutional factors that contributed to the col- laboration of neuropsychiatrist Warren McCulloch and mathematician Walter Pitts on the logic of neural networks, which culminated in their 1943 publication, “A Logical Calculus of the Ideas Immanent in Nervous Activity.” Historians and scientists alike often refer to the McCulloch–Pitts paper as a landmark event in the history of cybernetics, and funda- mental to the development of cognitive science and artificial intelligence. This article seeks to bring some historical context to the McCulloch–Pitts collaboration itself, namely, their intellectual and scientific orientations and backgrounds, the key concepts that contributed to their paper, and the institutional context in which their collaboration was made. Al- though they were almost a generation apart and had dissimilar scientific backgrounds, McCulloch and Pitts had similar intellectual concerns, simultaneously motivated by issues in philosophy, neurology, and mathematics. This article demonstrates how these issues converged and found resonance in their model of neural networks. By examining the intellectual backgrounds of McCulloch and Pitts as individuals, it will be shown that besides being an important event in the history of cybernetics proper, the McCulloch– Pitts collaboration was an important result of early twentieth-century efforts to apply mathematics to neurological phenomena. ᭧ 2002 John Wiley & Sons, Inc. -
Bio-R/Evolution in Historiographic Perspective: Some Reflections on the History and Epistemology of Biomolecular Science
VOLUME 11 ISSUE 1 2007 ISSN: 1833-878X Pages 4-13 Howard HsuehHsueh----HaoHao Chiang Bio-R/Evolution in Historiographic Perspective: Some Reflections on the History and Epistemology of Biomolecular Science ABSTRACT Does the molecular vision of life signify a unique revolution in biology or a more general evolution of the life sciences in the twentieth century? This paper visits this ‘big question’ by reflecting on a series of major debates in the historiography of molecular biology, especially those regarding its origins and the periodization of its development. For instance, while some have suggested that the discipline emerged in the 1930s, others have argued for its birth in the post-WWII era. Above all, the impact of the Rockefeller Foundation and the physical sciences on the formation of molecular biology remains a central topic of discussion among historians of biology. Unlike earlier historians of biomolecular science, recent scholars have also started to pay closer attention to the laboratory and material cultures that had conditioned its historical shaping. This paper argues that, ultimately, these debates all rest upon one fundamental historiographical problem: the absence of a unifying understanding of ‘molecular biology’ among historians (and practitioners) of biological science. This heterogeneous conceptualization of ‘molecular biology’, however, should be viewed as valuable because it allows for multiple approaches to resolving the ‘revolution versus evolution’ debate that together enrich our interpretation of the twentieth-century biomolecular vision of life. 4 BIOGRAPHY Howard Chiang is currently a Ph.D. student in the History of Science Program at Princeton University.

The Shannon Weaver Model of Communication Theory Script
Learning Outcome 1. Understand the importance of interpersonal skills related to health care practice 1.1 Analyse the appropriate use of interpersonal skills in three health care scenarios The Shannon Weaver Model of Communication Theory Script When you think about communication issues in the field of health and social care, it is helpful to break down the different components of the communication process. This way, you can think about all the different steps that take place in every interaction between you and a service-user or colleague, and about all the possible barriers or difficulties that might lead to a breakdown in communication. There are many models and theories that analyse the communication process. Here, we are going to look at one of the best-known: The Shannon-Weaver model. This model was first published in 1948, and it has been adapted, modified, and developed in many ways since. Claude Shannon was a mathematician and Warren Weaver was a scientist. They were primarily interested in “machine translation”, and how early computers, radios and televisions transmit information. However, the theory equally applies to human communication, and it remains hugely influential in modern social sciences. It is the foundation of most current communication theories, and for this reason, it is sometimes referred to as “the mother of all models”. The Shannon-Weaver model introduces 5 key stages to the communication process: • The sender • The encoder • The channel • The decoder • The receiver The sender is the person, group or organisation that first thinks of the message that they want to communicate. The encoder takes this message and turns it into signals. -
Rac Research Reports
ROCKEFELLER ARCHIVE CENTER RESEARCH REPO RTS Cross-Cultural Communication Theory: Basic English and Machine Translation at the Rockefeller Foundation by Rebecca Roach University of Birmingham © 2019 by Rebecca Roach Abstract My goal in conducting research at the Rockefeller Archive Center (RAC) was to identify the ways in which both the Rockefeller (RF) and Ford Foundations (FF) conceived of the relationship between literature and computing in their programs at mid-century. This research is central to my book project, Machine Talk: Literature, Computers and Conversation. In what follows, I lay out the background of this project and a research context that has often highlighted the intertwined emergence of computing and communication theory—and ignored the contributions made by the humanities to the development of this concept. I turn specifically to the RF Humanities Division, outlining its role in supporting early research into theories of communication—particularly cross-cultural communication—which would prove vital to the post-World War Two development of communication theory in the sciences. 2 RAC RESEARCH REPORTS Machine Talk My book project, Machine Talk: Literature, Computers and Conversation, examines two arenas that are often conceived in opposition to each other, namely literature and computing. This polarisation is visible in popular stereotypes around “nerdy” programmers and “purposeless” poets—and reinforced in national agendas that prioritise training in and funding of the sciences at the expense of the humanities, or in simplistic perceptions that arts students might bring “ethics” to a tech industry facing significant diversity and ethical problems. Such framings bolster C.P. Snow’s infamous “Two Cultures” binary, put forward sixty years ago.1 Yet these framings elide the significant material and conceptual common ground that literature and computing share and an intertwined trajectory in the post- World War Two years that has shaped our contemporary digital world. -
Recent Contributions to the Mathematical Theory of Communication
Recent Contributions to The Mathematical Theory of Communication Warren Weaver September, 1949 ClaudeShannon WarrenWeaver Abstract This paper is written in three main sections. In the first and third, W. W. is responsible both for the ideas and the form. The middle section, namely “2) Communication Problems at Level A” is an interpretation of mathematical papers by Dr. Claude E. Shannon of the Bell Telephone Laboratories. Dr. Shannon’s work roots back, as von Neu- mann has pointed out, to Boltzmann’s observation, in some of his work on statistical physics (1894), that entropy is related to “missing information,” inasmuch as it is related to the number of alternatives which remain possible to a physical system after all the macroscopically observable information concerning it has been recorded. L. Szilard (Zsch. f. Phys. Vol. 53, 1925) extended this idea to a general discussion of information in physics, and von Neumann (Math. Foundation of Quantum Mechanics, Berlin, 1932, Chap. V) treated information in quantum mechanics and particle physics. Dr. Shannon’s work connects more directly with certain ideas developed some twenty years ago by H. Nyquist and R. V. L. Hartley, both of the Bell Laboratories; and Dr. Shannon has himself emphasized that communication theory owes a great debt to Professor Norbert Wiener for much of its basic philosophy. Professor Wiener, on the other hand, points out that Shannon’s early work on switching and mathematical logic antedated his own interest in this field; and generously adds that Shannon certainly deserves credit for independent development of such fundamental aspects of the theory as the introduction of entropic ideas. -

Shannon published "A Mathematical Theory of Communication" in 1948, he could not foresee what enormous impact his findings would have on a wide variety of fields, including engineering, physics, genetics, cryptology, computer science, statistics, economics, psychology, linguistics, philosophy, and aesthetics.1 Indeed, when he learned of the scope of that impact, he was somewhat less than enthusiastic, warning his readers in "The Bandwagon" (1956) that, while "many of the concepts of information theory will prove useful in these other fields, [...] the establishing of such applications is not a trivial matter of translating words to a new domain, but rather the slow tedious process of hypothesis and experimental verification" (Shannon 1956, 3). For the author of this essay as well as my fellow contributors from the humanities and social sciences, Shannon's caveat has special pertinence. This is so because we get our understanding of information theory less from the highly technical "A Mathematical Theory -

Look it up in a library catalogue or an online bookstore and you could easily become confused. For example, you might be interested in finding out about public speaking or body language or journalism but find that your search is impeded by numerous entries for books on electronics. Or you might be researching the physics of the internet or telephones but instead find countless entries for books on negotiation, public relations and writing skills. So what’s going on? Right from the start — ironically enough — we find confusing communications about communication. The first task, then, is to establish the differences Communication is a between these two concepts. challenging concept, Communication (singular), as applied to human interaction, includes: with a search on ■■ body language or nonverbal communication ‘communication’ likely to ■■ bring up topics as diverse public speaking and presentation skills as team communication, ■■ journalism or writing for the mass media body language and ■■ graphic communication electronics. ■■ -

Indent in this process is the capability of improving the socio-economic condition of the villagers and uplifting them from illiteracy, poverty and diseases. The extension workers have the work of presenting useful ideas to the people for their upliftment, define those ideas and have them adopted. Therefore usually, the success of extension worker is determined by the efficiency of communicating the useful ideas to the people. The word ‘communication’ comes from the Latin word communis, its meaning is common. It means that when we communicate, we are trying to establish community with someone through a message. ‘Communication’ then is a conscious attempt to establish community over some idea, fact, feelings and the like, with others. -

What caught my attention was how the lives and work of the proponents of what has been come to be known as information theory were inter‐meshed during the late 1930s and 1940s. Wiener teaches a young Claude Shannon at MIT, but has relatively little contact with him at that stage. -

THE MATHEMATICAL THEORY OF COMMUNICATION by Claude E. Shannon and WarrenWeaver THE UNIVERSITY OF ILLINOIS PRESS . URBANA· 1964 Tenth printing, 1964 Also printed in paperbound edition, 1963 and 1964 First paperbound edition, 1963 Copyright 1949 by the Board of Trustees of t ho Umvorsity of Illinois. Manufactured in the United States of America. Library of Congress Catalog Card No. 49-11922. Preface Recent years have witnessed considerable research activity in communication theory by a number of workers both here and abroad. In view of the widespread interest in this field, Dean L. N. Ridenour suggested the present volume consisting of two papers on this subject. The first paper has not previously been printed in its present form, although a condensation appeared in Scientific American, July, 1949. In part, it consists of an expository introduction to the general theory and may well be read first by those desiring a panoramic view of the field before entering into the more mathe matical aspects. In addition, some ideas are suggested for broader application of the fundamental principles of communi cation theory. The second paper is reprinted from the Bell System Technical Journal, July and October, 1948, with no changes except the cor rection of minor errata and the inclusion of some additional references, It is intcnded that subscquent developments in the field will be treated in a projected work dealing with more general aspects of information theory. It gives us pleasure to express our thanks to Dean Ridenour for making this book possible, and to the University of Illinois Press for their splendid cooperation. -
Translation of Languages: Fourteen Essays, Ed
[Written 15 July 1949. Published in: Machine translation of languages: fourteen essays, ed. by William N. Locke and A. Donald Booth (Technology Press of the Massachusetts Institute of Technology, Cambridge, Mass., and John Wiley & Sons, Inc., New York, 1955), p.15-23.] Translation WARREN WEAVER There is no need to do more than mention the obvious fact that a multiplicity of languages impedes cultural interchange between the peoples of the earth, and is a serious deterrent to international understanding. The present memorandum, assuming the validity and importance of this fact, contains some comments and suggestions bearing on the possibility of contributing at least something to the solution of the world-wide translation problem through the use of electronic computers of great capacity, flexibility, and speed. The suggestions of this memorandum will surely be incomplete and naïve, and may well be patently silly to an expert in the field—for the author is certainly not such. A War Anecdote—Language Invariants During the war a distinguished mathematician whom we will call P, an ex-German who had spent some time at the University of Istanbul and had learned Turkish there, told W. W. the following story. A mathematical colleague, knowing that P had an amateur interest in cryptography, came to P one morning, stated that he had worked out a deciphering technique, and asked P to cook up some coded message on which he might try his scheme. P wrote out in Turkish a message containing about 100 words; simplified it by replacing the Turkish letters ç, ğ, ĭ, ö, ş, and ü by c, g, i, o, s, and u respectively; and then, using something more complicated than a simple substitution cipher, reduced the message to a column of five-digit numbers.
