Origami and Geometric Constructions
by Robert J. Lang
Number of pages: 55
Origami is the art of folding uncut sheets of paper into interesting and beautiful shapes. Within this text, the author presents a variety of techniques for origami geometric constructions. The field is rich and varied, with surprising connections to other branches of mathematics.

The book gives, in a simple way, the essentials of synthetic projective geometry. Enough examples have been provided to give the student a clear grasp of the theory. The student should have a thorough grounding in ordinary elementary geometry.

The volume naturally divides into three parts. Part I consists of 14 papers on the foundations of geometry, Part II of 14 papers on the foundations of physics, and Part III of five papers on general problems and applications of the axiomatic method.

This volume includes articles exploring geometric arrangements, polytopes, packing, covering, discrete convexity, geometric algorithms and their complexity, and the combinatorial complexity of geometric objects, particularly in low dimension.
