Pretty book of mystical lore related to geometry, but weak on math, November 15, 2006
This review is from: Sacred Geometry: Deciphering the Code (Hardcover)
This book is pleasant to browse, containing various lore about geometry, history, geography and the occult. It is very attractive visually, containing many nice photographs and diagrams. Unfortunately, given the important place of mathematics in the book, I am afraid to say that the author appears to know rather more about art and mysticism than he does about mathematics. For example, on page 52 we read: "For modern mathematics irrational numbers are those that cannot be pinned down to a few digits. They are, in fact, repeating decimals that go on forever." In fact, of course, irrational numbers are characterized by having decimal expansions that do not repeat. Also, on page 51, it is apparent that the author does not understand the construction of the mathematical curve known as the Conchoid of Nicomedes. This is a pity, because it would have been very easy to give the correct description since the relevant diagram is already included on the page.

A book that changed my view of the world around me!!, July 10, 2007
This review is from: Sacred Geometry: Deciphering the Code (Hardcover)
XXXXX
QUESTION: What do the following have in common? A daisy, an eagle's beak, snowflakes, structure of DNA, Egyptian pyramids, crop circles, the stable elements of the periodic table, and Leonardo da Vinci's "Last Supper."
ANSWER: They are all based on geometry or numbers that are considered "sacred."
This is exactly what "world-renowned expert" Stephen Skinner shows the reader in this beautiful and informative book: how certain types of geometry (a Greek word that means `measurement of the Earth') and numbers are considered sacred.
Geometry was one of the first branches of mathematics to be extensively developed. Long before the Christian era, the Egyptians and later the Greeks had made exhaustive studies of the properties of geometrical figures. While the Egyptians were concerned mainly with practical applications (witness the pyramids), the Greeks were interested in the mental exercise involved in the study of Geometry. Many of these ancient Greek scholars believed that if they pursued the study of geometry far enough they would unlock some of the deepest mysteries of the universe.
Thus we have geometry and numbers that they and other civilizations considered sacred. Why sacred? Because they arrange systematically the hidden order of creation.
The book itself is divided into parts. These are entitled (1) The hidden order (2) The geometry of nature and (3) The geometry of the [human] made world. Each part begins with a brief overview (in italics) that summarizes a particular part.
Each part itself is divided into chapters. Here are the chapter titles for part (3): (i) Sacred geometry and the landscape (ii) Sacred geometry in architecture and (iii) Sacred geometry in art.
Each chapter is divided into sections. The sections for the chapter entitled "Pure arithmetic" are as follows: (I) Pythagoras and the worship of number (II) Music, vibration, and whole numbers (III) The value of fractions (IV) Measuring the Earth with two sticks (V) Original units of measurement (VI) The curious nature of prime numbers and (VII) The Golden Mean--the arithmetic of growth.
A highlight of this book are the many mainly color and truly beautiful pictures and illustrations. I counted almost 200. By the way, the picture on the book's cover (displayed above by Amazon) is a "nautilus shell," a "living spiral" actually found in nature.
Another highlight of this book are its numerous tables of significant numbers that reveal a pattern. My favorite is entitled "The [Egyptian] Pyramids and their Dimensions."
Yet, another highlight are the numerous isolated (from the main narrative) boxes that contain information the author feels is important for the reader to know. My favorite is entitled "Visual tricks" that describes "one of the unique tricks of geometry incorporated into the [ancient temple called the] Parthenon [of Athens, Greece]."
Want to know how to draw a special type of snowflake (called a Koch snowflake)? How about a special curve known as the logarithmic spiral? This book provides step-by-step constructions (in isolated boxes outside the main narrative) on how to draw (using a compass and ruler) these geometric figures and others.
Fans of Dan Brown's book "The Da Vinci Code" should find the material in the last chapter entitled "Sacred geometry in art" very interesting.
There are a few non-serious typos in this book. Unfortunately, a typo occurs for a definition of irrational numbers. The author states:
"Irrational numbers are those that cannot be pinned down to a few digits. They are, in fact, repeating decimals that go on forever." Examples include the square root of 2, the square root of 3, and the square root of 5."
The second statement in the above quotation is actually incorrect. But this is a typo. How do I know this? By the third statement above. The square root of 2 is 1.4142136..., the square root of 3 is 1.7320508..., and the square root of 5 is 2.236068.... The typo is that they're non-repeating decimals (not repeating decimals).
I make it a policy not to condemn books that have a few typos unless they're in too many key spots.
Finally, the only problem I had with this book is that I don't really know anything about the author, Stephen Skinner. We're told on the book's back cover that he's a "world-renowned expert" and that's it! I would have liked to have known more about the author.
In conclusion, this remarkable book changed my view of the world around me!!
(first published 2006; introduction; 3 parts or 7 chapters; conclusion; main narrative 150 pages; bibliography; index; acknowledgements)

Beautiful review of the Mathematics of Nature and Magic, December 1, 2006
This review is from: Sacred Geometry: Deciphering the Code (Hardcover)
This glorious book has been written by Stephen Skinner - who introduced Chinese Geomancy (or Feng Shui if you prefer) to the West in the 1960's with his ground-breaking (literally!) book "The Living Earth Manual". Since then he has produced a number of highly respected books on a variety of Feng Shui, Geomancy and Magical topics.
This new book brings together his broad knowledge of many different religions, sacred philosophies and magic, and his expertise in mathematics and geography.
Dozens of different sections with glorious photography and elegant line drawings show you how nature is based on elegant equations and then leads you through the millenia of ancient mathematics, as the geniuses of the past 2 or 3000 years intricately link mathematics and architecture. Whether it is the Fibonacci series, or the Greeks PI, or the circles of Dante's Hell - everything is clearly explained - you are thrilled at how Nature takes advantage of some of the most beautiful pure mathematics and the scale of the intellects who designed and built these magical places.
Stephen Skinner's book is a wonderful place to start - and will, no doubt, be the spur for many trips and explorations.
If you enjoyed the "Da Vinci Code" - get this book and read about REAL codes, enigmas and mathematics that can be found hidden in some of the world's most amazing buildings.
This book is for those of us who revel in the glorious elegance and simplicity of mathematics as applied to ALL good design (whether Natural or Human) - and is not aimed at mathematicians specifically.
