L. Mahadevan - Folds, cuts and isometries: art and science

For millennia, origami and kirigami artists have used folds and cuts to create beautiful shapes from a simple sheet of paper. I will describe our recent scientific attempts to catch up with these remarkably imaginative arts phrased as inverse problems in physical geometry that aim to control the shape and rigidity of a thin surface. Using discrete operations that vary the number, size, orientation and coordination of folds and cuts, I will show how to create piecewise isometric kirigami and origami tessellations and control their local and global morphology and mechanical response, mixing experimental, computational and theoretical approaches.

L. Mahadevan is the Lola England de Valpine Professor of Applied Mathematics, of Organismic and Evolutionary Biology, and of Physics at Harvard University. His interests are broadly in the study of motion and matter at the human scale, where phenomena are robust and easy to observe, yet not always easy to explain. These include the patterns of shape and flow of inanimate matter on scales ranging from the supramolecular to the planetary, and the dynamics of sentient living matter that can self-organize, perceive and act. In all cases, the aim is to get at a qualitative understanding using quantitative methods, and get at general principles, if there be such, from answers to specific questions. His work has been recognized by a number of awards: he is notably a MacArthur Fellow and a Fellow of the Royal Society of London.
