Mathematical Theory of Communication

Summary:
Few books have had as lasting an impact or played as important a role in our modern world as The Mathematical Theory of Communication. Claude Shannon´s major precept, that all communication is essentially digital, is now so commonplace among the modern digitalia that many wonder why Shannon needed to state such an obvious axiom.
The origin of this book lies in the Bell Telephone Laboratories initiative in researching how wireless and telecommunications can be improved. The problem it deals with is a classic one for electronics, telecommunications and computing - noise vs. fidelity of data transmitted. The solution it propounds is simple and yet so revolutionary that it charted the course of these fields since it was published.
The basic premise of the book is that *redundancy* or elimination of noise occurs at infinite time. *Entropy* or shuffledness allows for some noise and produces more information because it requires reconstruction at the receiving end.
The authors support their arguments with simple statistical formulae which explain how entropy and redundancy are inverse of each other.
This book has been highly debated by both the people involved in the fields concerned and the people outside the field.
Most of the debate surrounds the controversial aspect of Shannon and Weaver´s definition of information in engineering terms, which excludes issues like relevance, meaning etc.
A great deal of debate also got carried into social sciences and humanities where a new celebration of *entropy* occured.
