Alphabet Mystery Books

This book offers a journey through the history of the figures, numbers and relationships. We must not lose sight of our decimal system, for us as well known, simple and natural, is the result of centuries of evolution in which different cultures have been shaped, not without great effort, its diverse representation, to reach we now enjoy and which has enabled the current scientific development. The author, born in Paris, not a mathematician, is a rabbi and a doctorate in philosophy and has published numerous books that have little to do with mathematics: "The mysteries of the alphabet," "The Mysteries of the Kabbalah" or "story Beauty of God: Who is the God of the Bible? ". The raid carried out in the world of numbers can be considered as a result of his research on the development of the earlier books. As he says, has been diving into the world of mathematical ideas gradually, as he wrote this book because I had already forgotten what they were integers and rational numbers, and how was fascinated to rediscover. In this research, the figures are not absent, is more we could say that prominently, esoteric or magical aspect that undoubtedly accompanied the numbers in its evolution and development: philosophical, literary and mathematical. The author clearly distinguishes the figures of the numbers, the concept of representation: a unique concept, the number four, has various representations in different cultures: 4, IV,, . . The figure is a linguistic fact or figure, the number exists beyond the numbers. The text is organized into three books. The first, on the Numbers: birth and evolution, starts its journey in India with its essential contribution to the decimal system position and explores the relationship between the figures and the evolution of writing. Then comes the passage of the Indian figures to indoárabes and Western Europe and the analysis of the key elements in this process: the work of Gerbert of Aurillac, the importance of cross-translations of Greek works, Arabs and Hindus to Latin. Besides, the difficulties in the acceptance of zero, the importance of Fibonacci or disputes between ABAC and algorists. Besides this, there are other aspects that have nothing to do with our science today, as the Kabbalah, the gematria and other procedures relating letters and numbers. In the second book, about the numbers, starting with Pythagoras and the Pythagorean school numbers classified in different types: natural, integer, rational, irrational, friends, cousins, . . We offer the kabbalistic interpretation of the numbers: for example, lists the names of God to their numerical value, that little or nothing to do with mathematics and self-interest rather non-scientific interest. The third book on magic squares and talismans, refers to the relationships between these numbers and magic squares Kabalistic interpretations. Interpretations that, at least for a reader unaware of these magical secrets are absolutely forced to make the numbers say what the interpreters of the scriptures want them to say. In conclusion we can say that, first, for fans of historical mathematical aspects of this book, which deals specifically with the history and evolution of the figures and on the other hand, reminds the famous book of Georges Ifrah "Figures. The story of a great invention," they certainly prove interesting. Furthermore, the inclination toward magical or esoteric aspects, in which interpretations arise stakeholders seeking to rely on scientific neutrality of the numbers to support certain positions or options unscientific, can collide with any minimally critical spirit. . .
