Congratulations to Lloyd Kaufman for this substantial and very satisfying book! The book is well written and amply illustrated with clear diagrams. There are good examples and analogies throughout the book. The explanation of Fourier analysis is exceptionally satisfactory with respect to most texts on that subject, and it should be understandable to the average reader. Controversial issues of research are presented with fairness. The material is organized in four major sections (Intoduction to Perception; Light and Color; Space Perception; Form and Information Processing) comprising a total of fourteen chapters. The reader can easily follow the logical steps that the author takes to convey the essence of what is known about visual perception. At the same time, the author seems to succeed in the difficult task of motivating the reader time after time. There are many instances when one feels the challenge of the unknown and the excitement of seeking solutions to old or new problems. The reader will find only a negligible number of typographical errors (unfortunately, there is one in the name of 0. W. Holmes). There are a few words such as “randomicity” and “complementarity” that should not have appeared in this fine book. This reviewer feels that there is a need for this kind of a book to anticipate and answer in advance such questions as “what if I don’t see it?” In other words, what should the normal, intelligent reader think when occasionally he doesn’t see in a picture what the book tells him he should be seeing?

Logic design of digital systems has been a very efficacious “art” for thirty years, largely without the benefit of supporting theory. To derive this relationship between logic design and switching theory and other relationships between related intellectual activities, this book begins by reviewing switching circuit technology from the relay to LSI and related digital system timing techniques. It then shows how sequential circuit models and theory originated in that technology and attempts to codify logic design and system timing procedures and practices. With this background it nicely presents the relationships in Chap. 4. Very frequent references to and quotes from the literature substantiate and present many of the conclusions that are drawn. This book might be viewed as a history book; older designers may enjoy it as such. It clearly does not teach logic design, but has a great deal to offer the advanced student of logic design or switching theory. The review chapters reveal the wide range of technologies and techniques explored in the past; this must broaden the student as well as give him an appreciation for current technology and possibly prepare him for future technologies. The last chapter places technology, logic design, switching theory, and programming in perspective, and thus might be considered to be essential reading for practical and theoretical oriented students (and professors and practicing designers) alike. Langdon did an excellent job; one may wish that he had also treated combinational switching theory.
