Mathematical Origami

the long version

Origami is the art of paper folding without the use of scissors or glue. The instructions are given in the form of clearly labelled diagrams. Each of the beautiful and fundamental shapes described in this book is achieved simply by folding sheets of standard A4 paper. For this book David Mitchell has gathered together a most impressive collection of models and ideas which will amaze and interest mathematics teachers and anyone who admires pure geometrical forms. The models in this book are examples of the relatively new mathematical art of modular paperfolding, in which a number of simple folded modules are assembled to create a polyhedral model.
