Shapes, Space, and Symmetry (Dover Books on Mathematics)

This book is beautiful. It is easy to read and the ideas are beautifully illustrated through photos of models created by the author, a real feat given the 3D subject. A guide for building the models is included; as the author states, the best way to learn about these shapes is to build them. The book carefully and succinctly guides the non-mathematician through fascinating and illuminating transformations of regular polyhedra using their symmetries and duality.For the artist or craftsman who wants to make something inspired by polyhedra, this book is perfect. This is one of my favorite books because every time I pick it up I have a new idea for something to make.

I love this book. I got it thinking I wouldn’t like it and was pleasantly surprised by how good it is. The concepts covered are well explained both with words and visuals and the concepts covered flow coherently throughout the whole book. One I am proud to have in my geometry collection.

This is a fascinating book if you're doing a deep dive on geometry. Good complement to Synergetics and a fantastic addition for anybody with a 3d printer. I was personally interested in the concept of "nolids" and this book describes them in some detail. I was so happy with this book, I bought a copy for a friend as a gift.

Filled with photos and good information on polyhedra. Since most math courses in high school do not discuss these shapes, this book was perfect for learning about the topic.

Detailed text, many photographs of a large collection of well made models and clear figures bound together by concise, casual text. If you are interested in solid geometry for any reason, this book belongs in your collection.

gave me a much better understanding of the variety of 3D forms. Very methodical. Shame the cover doesnt do it justice. Look inside !

This book illustrates many beautiful ideas through photographs of paper models with concise commentary. First the regular polyhedra, of course, followed by variations of the models that brings out their duality and symmetry properties. We also study how the regular polyhedra can be compounded, inscribed in each-other, and pasted together along a common cross-section ("when halves of the Platonic solids having the same cross-sections come together, monsters are born"). We also study truncating the regular polyhedra to obtain the semi-regular polyhedra, stellating to obtain non-convex regular solids, and faceting to obtain non-convex semi-regular polyhedra. There is a deplorably short but somewhat useful section with practical advice on building models. "Suitable cardboard is of the sort used for mounting photographs, and suitable glue is a 'white glue' of the sort exemplified by 'Elmer's Glue-all' ... For several hours the joints remain sufficiently flexible to permit adjustment of the dihedral angle". It's a pity that we are advised to construct the sides of the regular polyhedra by unromantic means; equilateral triangles are to be made using "a draftsman's 30-60-90 triangle" and the construction of a regular pentagon "requires a guide made of heavier cardboard, such as an illustration board, with two edges meeting at the desired angle"---obviously you will want to construct the faces using ruler-and-compass constructions.

Alan Holden must be a very dedicated man. This short book on polyhedra is filled with pictures of intricate paper models, all made by the author. In the final section, showing how to construct similar models, one can see a photo of his workshop with hundreds of models arrayed neatly on shelves behind him. This book was clearly a work of love.Most of the book is occupied with a treatment of regular and semiregular polyhedra, prisms and antiprisms. These are examined in some depth--for example, all nine regular polyhedra are constructed. The last fifty pages introduce other topics, such as packing, lattices, and knots; the treatment here is very brief, somewhat disappointing and leaving a desire for more depth. The same can be said of the final section, on construction--Holden gives general guidelines but leaves the reader to compute the dimensions of all the faces of his models himself.The prose is clear and concise, rare for a mathematics book. But the real substance lies in the photographs of polyhedra models. These are contructed in such a way that it is always easy to see the details of the solid: faces of different shapes are made of different shades of paper, complicated models are shown in intermediate stages of construction, polyhedra to be compared (such as duals) are shown as individuals and interpenetrating. The great icosidodecahedron photo on page 112 (or its companion that might go by the same name on page 98) is almost worth the price of the book by itself.This is not a rigorous treatment of the subject, but it is a beautiful one.

Must read for anyone trying to understand topology, extremely useful illustrations.
