This easytoread book demonstrates how a simple geometric idea reveals fascinating connections and results in number theory, the mathematics of polyhedra, combinatorial geometry, and group theory. Using a systematic paperfolding procedure it is possible to construct a regular polygon with any number of sides. This remarkable algorithm has led to interesting proofs of certain results in number theory, has been used to answer combinatorial questions involving partitions of space, and has enabled the authors to obtain the formula for the volume of a regular tetrahedron in around three steps, using nothing more complicated than basic arithmetic and the most elementary plane geometry. All of these ideas, and more, reveal the beauty of mathematics and the interconnectedness of its various branches. Detailed instructions, including clear illustrations, enable the reader to gain handson experience constructing these models and to discover for themselves the patterns and relationships they unearth. 


Dynamical Systems and Fractals: Computer Graphics Experiments with PascalThis study of chaos, fractals and complex dynamics is intended for anyone familiar with computers. While keeping the mathematics to a simple level with few formulas, the reader is introduced to an area of current scientific research that was scarcely possible until the availability of computers. The book is divided into two main parts; the...   Spinning the Semantic Web: Bringing the World Wide Web to Its Full Potential
The Semantic Web is the realization of an aspect of the Web that was part of the original hopes and dreams of 1989, but whose development has, until now, taken a back seat to the Web of multimedia humanreadable material. Even though at the first WWW conference, in 1994, I ended my talk with a few slides about the Semantic Web, the steps...   Bacteriology of Humans: An Ecological PerspectiveUntil recently, the indigenous microbiota of humans has been a relatively neglected area of microbiology with most attention being focused on those microbes that cause disease in humans, rather than on those that coexist with us in the diseasefree state. However, in the past decade research has shown that not only is the indigenous microbiota...
