“In origami design, historically people have always used their intuition. They probably started by folding traditional shapes or folding designs by others, developed an intuitive understanding of how the paper behaves and then from there they can explore that intuition to create new shapes. That was the way design worked for years and years, that was the way it worked for me, but I eventually hit a limit to what I could do with my intuition and so part of my motivation for exploring mathematical methods was to externalise some of the design process. If I could get some of the design process on paper in a meaningful way, then I could handle more complicated goals than I could just fit in my brain.”Robert J. Lang has been working with origami for over fifty years and is now recognized as one of the world’s leading masters of the art and one of the pioneers of the marriage of origami with mathematics and technology. He has consulted on applications of origami to medical devices, airbag design, and space telescopes, is the author or co-author of twenty-one books and numerous technical articles, and lectures and consults on the connections between origami, science, and technology.· langorigami.com· www.creativeprocess.info
