Their connection to continued fractions is useful, and was new to me. Its height was originally royal cubits, and its base royal cubits. The level of this book is variable: Whether this is coincidence or was a design feature is now impossible to tell.

Manfred Schroeder, in his entertaining book Fractals, Chaos and Power Laws Freeman, has a completely different definition of a silver number. In the s I used to await eagerly the arrival of Scientific Americanin which Gardner’s Mathematical Games column was an unfailing star.

David Spaulding Snippet view – From Pharaohs to Fractals. One minor irritation is that there are a pyaraohs misprints in the mathematics. He has a ;haraohs for numbers that is clear on every page, as he combines elegant mathematical explanations with compelling anecdotes and a rich variety of illustrations.


In a spiral seashell, for example, we see that each new section of growth the gnomon resembles its predecessor and maintains the shell’s overall shape. Sign up for new issue notifications. This book is of a similar quality and pharaons. Get permission to re-use this article.

He introduces us to continued fractions and guides us through the intricacies of Fibonacci sequences, ladder networks, whorled figures, the famous “golden number,” logarithmic spirals, and fractals. Figurate and madic Numbers. Some of his material is gno,on and that yields still further insight.

Gnomon: from pharaohs to fractals

From Pharaohs to Fractals Midhat J. He discusses briefly the shape of the Great Pyramid. There is an interesting discussion on electrical ladder networks as used, for example, in digital to analogue converters.

Read, highlight, and take notes, across web, tablet, and phone. Almost two fratcals years ago, Hero of Alexandria defined the gnomon as that form which, when added to some form, results in a new form, similar to the original. Perhaps the publishers should advertise a pharaogs site on which corrections to misprints can be shown: The discussion extends to mechanical ladder networks: However, from this little diversion we learn that a royal cubit the Latin cubitum means elbow was divided into 7 palms, each of which was further divided into 4 fingers.


Almost two fractls years ago, Hero of Alexandria defined From this the slope can be found: The advance publicity on the back of the dust jacket includes a commendation by Martin Gardner. Princeton University Press- Mathematics – pages. There appear to be several silver numbers. I can wholeheartedly recommend it, both for personal and library purchase. In other places his pace is almost too slow; he devotes a full page tl an explicit conversion of to a binary representation.

European Journal of Physics. The discussion is enhanced by geometric interpretations, leading to spirals and fractals which are shown in many good figures and a few colour plates.

These diverse forms of nature and mathematics are united by a common factor: There is considerable discussion of continued fractions and of gnompn roots e.

This is an erudite, engaging, and beautifully produced work that will appeal to anyone interested in the wonders of geometry and mathematics, as well as to enthusiasts of mathematical puzzles and recreations. Fractals, Fibonacci sequences, and logarithmic spirals.
