3D Origami Art

Easily Create Origami with Curved Folds and SurfacesOrigami making shapes only through folding reveals a fascinating area of geometry woven with a variety of representations. The world of origami has progressed dramatically since the advent of computer programs to perform the necessary computations for origami design.3D Origami Art presents the design methods underlying 3D creations derived from computation. It includes numerous photos and design drawings called crease patterns, which are available for download on the author‘s website. Through the book‘s clear figures and descriptions, readers can easily create geometric 3D structures out of a set of lines and curves drawn on a 2D plane.The author uses various shapes of sheets such as rectangles and regular polygons, instead of square paper, to create the origami. Many of the origami creations have a 3D structure composed of curved surfaces, and some of them have complicated forms. However, the background theory underlying all the creations is very simple. The author shows how different origami forms are designed from a common theory.

The Non-Aligned Movement (NAM) is the largest and most diverse political grouping of states engaged on issues related to nuclear nonproliferation and disarmament. Drawing on the authors first-hand experiences as members of NAM observer-state delegations in NPT and IAEA negotiations, as well as the findings of a larger CNS research project on NAM nuclear politics, the book will provide important new insights about how a small subset of NAM states has tended to dominate NAM politics and have promoted policies that are often at odds with those advanced by Western states on issues such as nuclear terrorism, IAEA safeguards, nuclear export controls, multinational fuel arrangements, proliferation in the Middle East, NPT, and nuclear arms control and disarmament. Based on an analysis of NAM perspectives, politics, and priorities, the book will provide practical recommendations for engaging NAM members in a more constructive fashion on issues related to nuclear nonproliferation, disarmament, peaceful use, and counter-nuclear terrorism. Particular attention will be given to problems likely to be encountered when Iran assumes the chairmanship of NAM in 2012 and how these difficulties can best be mitigated in the lead up to the next NPT Review Conference.
