Design for a brain

296 p., ref. bib. : 1 p.3/4Cybernetics has been defined as "the science of control and communication, in the animal and the machine "-in a word, as the art of steersmanship; and this book will interest all who would learn something of cybernetics, communication theory and methods for regulation and control. The author has specialised in the applications of cybernetics to biological systems, and his treatment is quite new and much simpler and clearer than that generally used. This book is intended to provide an introduction to the subject. Starting from common-place and well-understood concepts it proceeds step by step, to show how these concepts can be made exact and how they can be developed until they lead into such subjects as feedback, stability, regulation, ultra- stability, information, coding, noise, and other cybernetic topics. ' Throughout the book no knowledge of mathematics is required beyond elementary algebra. An important feature is the number of carefully graded exercises, with hints and explanatory answers, so that the reader, as he progresses, can test his grasp of what has been read. The book is mainly intended as a self-instructor but will also be found valuable as supplementary reading for a course in communication theory
