From the reviews:„Benschop develops this thesis in an idiosyncratic fashion, reinforced by a long career of practical experience. This book may well be an important historical document, also useful for seminars … . There are profuse illustrations in classic number theory, as well as claims that the outlook sheds new light on classic problems such as those of Fermat and Goldbach, interpreted as machines. … it makes for an interesting book.“ (Harvey Cohn, ACM Computing Reviews, August, 2009)“The book presents new ways for modeling digital networks (state machines, sequential and combinational logic). It contains applications for known principles of the discrete mathematics. … book also presents new ideas on the finite additive number theory and a binary logarithmetic microprocessor. This book can be very useful for students and professors and also for researchers interested in the digital network theory. It covers a lot of fields, ranging from electrical engineering to computer science and applied mathematics.” (Eleonor Ciurea, Zentralblatt MATH, Vol. 1169, 2009)
