Norbert Wiener (1894-1964) is well known by the general public as
the founder of Cybernetics, by mathematicians as one of the first
north-American mathematicians who win international prestige - as
the person who formalized Brownian motion, solved the Zaremba
problem and was the author of two seminal papers devoted to
Generalized Harmonic Analysis and Tauberian Theorems - and by
engineers as the person who proposed much of the Fourier analysis
used by them and contributed to the foundation of the statistical
theory of communication - which includes the use of wave filter
theory, information theory and prediction theory in control and
communications as well as the automation of all types of electronic
devices.Wiener's research, which was frequently motivated by
physics, engineering, or biology, was a clever mixture of Fourier
analysis and probability theory. His contributions to electronics
through his work on filtering (that is, the separation of noise
from a message), and the theory of prediction made him very
valuable to electronics engineering. In addition, Wiener addressed
many other topics, including the formalization of the Brownian
motion, ergodic theory, wave filter theory, and information theory.
Taking all these ingredients together, he ventured to create a new
scientific paradigm: cybernetics.This book contains a detailed
explanation of Wiener's life, his many colleagues, and the
historical context in which he lived, as well as Wiener's work. It
also contains a large appendix about 'Wiener, Shannon, and the rise
of a Digital World'. The main focus of the book is on Wiener's work
related to electrical and electronic engineering and the way he
used his mathematics to create the main concepts and techniques of
the statistical theory of communication. In particular, the author
presents Wiener surrounded by the engineers that worked at MIT with
whom he maintained strong contact. It was in this atmosphere that
information theory arose, and Wiener was a main influence on the
people who developed that theory.
