Mathematical Curiosities All the colourful models in this collection, when cut out and glued together have curious and interesting properties. Some rotate, some fold and unfold, some twist and others fit together in unexpected ways. All illustrate mathematical ideas in an amusing and interesting fashion. Also included is a minibook which gives background information and further ideas. |
More Mathematical Curiosities A further collection of colourful models offering insights into mathematical concepts and including a minibook of background information and ideas. £4.95 (No VAT on this product) | |||||
The Magic of Flexagons Flexagons are made by folding paper in certain ways and when they are flexed, turned and unfolded in different ways, they show puzzling and curious effects. Some of this extensive collection are in the form of puzzles to be solved, others have rather mysterious properties. £4.95

Mathematical Origami Origami is the art of paper folding without the use of either scissors or glue. Each of the beautiful and fundamental mathematical shapes described in this book is achieved by folding sheets of standard A4 paper. It is remarkable what can been done and David Mitchell gives clear step by step instructions for each. He has gathered together a most impressive collection which will amaze and interest mathematics teachers and other admirers of pure geometrical forms. £5.95

Fractal Cuts The fractal cuts in this book are used to create attractive pop-up cards. Each is made from a single sheet of white paper cut according to a fractal rule and glued within a brightly coloured cover. Just as fractal images gain ever more beauty and complexity by the repetition of a simple rule, so it is fascinating to see how each pop-up fractal cut develops. Combining theory and practice in a satisfying way, there is the pleasure in making the card itself, followed by the delight of seeing it as an illustration of a fractal idea. Backed up by imaginative and informative text, this book will be of interest to all who have ever wondered about the significance of the ideas suggested by fractals. £6.95

Metamorphs Metamorphs are curious and interesting paper models which will transform step by step through a sequence of different shapes before finally returning to their original starting positions. There are ten colourful two and three-dimensional models to cut out and make and also an informative text which discusses and explains the principles by which they have been designed. There are two main classes of these objects and both are well represented in this collection, together with an introduction to the importance of degrees of freedom and the limitations of hinges and hinge lengths. Some people will prefer to see metamorphs simply as amusing and rather impressive toys, others as expressions of mathematical principles to be understood and appreciated. £5.95 (No VAT on this product) | ||||

Sliceforms Sliceform modelling is a technique which lies happily on the borders between art and mathematics. The models are made from intersecting sets of parallel planes which slot together in a clever way to generate interesting three-dimensional surfaces. In the 'fully open' position the planes are at right angles and the surfaces are correctly defined, but all the models fold flat in two different ways, making them easy to store until they are wanted next time. When 'popped up', the play of light and shade on the planes creates objects of great beauty. The book includes a varied collection of eight models to cut out and make and a detailed explanation of how to generate the slices for models of your own. £4.95

Sliceform Surfaces This colourful poster shows many examples of the beautiful models which can be made using the technique of sliceform modelling. This is a technique for creating three-dimensional surfaces from two intersecting sets of paper sections. The surface is suggested by the edges of the paper slices so that the volume of each model has little actual substance. However, the interplay of colour and shadow on the slices gives the models an almost magical quality. It is a fine way of demonstrating the beauty inherent in mathematical forms. | ||||||||
