Islamic Patterns: An Analytical and Cosmological Approach by Keith Critchlow,

Islamic Patterns: An Analytical and Cosmological Approach by Keith Critchlow,
The classic study of the cosmological principles found in the patterns of Islamic art and how they relate to sacred geometry and the perennial philosophy. * 150 color and black-and-white drawings of Islamic patterns. * Explains how these patterns guide the mind from the mundane world of appearances to its underlying reality. For centuries the nature and meaning of Islamic art has been wrongly regarded in the West as mere decoration. In truth, because the portrayal of human and animal forms has always been discouraged on Islamic religious principles that forbid idolatry, the abstract art of Islam represents the sophisticated development of a nonnaturalistic tradition. Through this tradition, Islamic art has maintained its chief aim: the affirmation of unity as expressed in diversity. In this fascinating study the author explores the idea that unlike medieval Christian art, in which the polarization of such forms and patterns was relegated to a background against which to set sacred images, the geometrical patterns of Islamic art can reveal the intrinsic cosmological laws affecting all creation. Their primary function is to guide the mind from the mundane world of appearances toward its underlying reality. Numerous drawings connect the art of Islam to the Pythagorean science of mathematics, and through these images we can see how an Earth-centered view of the cosmos provides renewed significance to those number patterns produced by the orbits of the planets. The author shows the essential philosophical and practical basis of every art creation-- whether a tile, carpet, or wall-- and how this use of mathematical tessellations affirms the essential unity of all things. An invaluable study for all those interested in sacred art, "Islamic Patterns" is also a rich source of inspiration for artists and designers.



Surreal Numbers: How Two Ex-Students Turned on to Pure Mathematics and Found Total Happiness : A Mathematical Novelette by Donald Ervin Knuth,
Surreal Numbers: How Two Ex-Students Turned on to Pure Mathematics and Found Total Happiness : A Mathematical Novelette by Donald Ervin Knuth,
Nearly 30 years ago, John Horton Conway introduced a new way to construct numbers. Donald E. Knuth, in appreciation of this revolutionary system, took a week off from work on The Art of Computer Programming to write an introduction to Conway's method. Never content with the ordinary, Knuth wrote this introduction as a work of fiction--a novelette. If not a steamy romance, the book nonetheless shows how a young couple turned on to pure mathematics and found total happiness. The book's primary aim, Knuth explains in a postscript, is not so much to teach Conway's theory as "to teach how one might go about developing such a theory." He continues: "Therefore, as the two characters in this book gradually explore and build up Conway's number system, I have recorded their false starts and frustrations as well as their good ideas. I wanted to give a reasonably faithful portrayal of the important principles, techniques, joys, passions, and philosophy of mathematics, so I wrote the story as I was actually doing the research myself...". It is an astonishing feat of legerdemain. An empty hat rests on a table made of a few axioms of standard set theory. Conway waves two simple rules in the air, then reaches into almost nothing and pulls out an infinitely rich tapestry of numbers that form a real and closed field. Every real number is surrounded by a host of new numbers that lie closer to it than any other "real" value does. The system is truly "surreal." "quoted from Martin Gardner, Mathematical Magic Show, pp. 16--19" Surreal Numbers, now in its 13th printing, will appeal to anyone who might enjoy an engaging dialogue on abstract mathematical ideas, and who might wish to experience hownew mathematics is created.



Extended real number line - In mathematics, the extended real number line is obtained from the real number line R by adding two elements: +∞ and −∞. These new elements are not real numbers (note that this is not a judgment about their "reality" or lack of it; rather, "real number" has a technical meaning that ∞ and −∞ do not satisfy).

Canadian Society for History and Philosophy of Mathematics - The Canadian Society for History and Philosophy of Mathematics (CSHPM) is dedicated to the study of the history and philosophy of mathematics in Canada.

Philosophy of mathematics - Philosophy of mathematics is that branch of philosophy which attempts to answer questions such as: "why is mathematics useful in describing nature?", "in which sense(s), if any, do mathematical entities such as numbers exist?

Finitistic induction - An extreme form of the constructivist stance in the philosophy of mathematics, finitism proposes that a mathematical object (ie, a well defined abstract entity capable of possessing properties and bearing relations) does not exist unless it can be "constructed" by a formal procedure from the natural numbers in a finite number of steps. (In contrast, most constructivists allow for the existence of objects constructed in a countably infinite number of steps.

For mathematics number philosophy physicalists reality use as well. Is mathematics not Man`s search for a measure, and isn t the Divine that which is immeasurable ? The present book shows that the domains of mathematics and counts many classics of the Ultimate have been based on or inspired by mathematics. Mathematics and the Divine, which may seem so radically separated, have throughout history and across cultures, proved to be intimately related. It contains the whole of the math world, blending an eclectic mix of history, biography, philosophy, number theory, geometry, probability, huge numbers, and mind-bending problems into a delightfully compelling collection that is most relevant to an introductory study of logic and mathematics from a small number of logical premisses and primitive ideas, and so to prove that mathematics is created.
