The Anthropic Cosmological Principle John D. Barrow, Frank J. Tipler
Publisher: Oxford University Press, USA

The anthropic principle was first enunciated by the mathematician Brandon Carter in 1974. The anthropic principle takes two primary forms: the weak (WAP) and the strong (SAP). Further elaboration and consolidation came in 1986 in the form of a book The Anthropic Cosmological Principle by Barrow and Tipler. The cosmological constant has to be fine-tuned to the order of $10^{123}$. The anthropic principle is now widely accepted among physicists, and there are several good books that explain it in comprehensive detail. One of the most interesting features of theoretical investigations of the anthropic principle is that biological entities of our type are related to a particular cosmology (dimensional structure) in our universe. Why doesn't the anthropic principle select for N=2 SUSY compactifications with an exactly zero cosmological constant? One of the more interesting points that Barrow raises in his book 'The Constants of Nature' is that conditions of the anthropic principle-the Recent speculation has found evidence against inflation as a fact of cosmological mechanics, or at least problems with it, even so, considering principles that apply to any given universe such as a chaotic inflationary one provide a modal logic of neccessity criteria in support of the anthropic principle's validity. The Anthropic Cosmological Principle, a theory developed in the 1980s by scientists Barrow and Tippler, answers. In the last two decades or so, however, the anthropic principle has acquired something of a bad press, as cosmologists have used it to try and explain the mystery of dark energy. Many people are aware of the Weak and Strong Anthropic Principles.
