The hidden elegance in everyday objects and physical mechanisms, from crumpled paper to sandcastles.
Hidden Wonders focuses on the objects that populate our everyday life—crumpled paper, woven fabric, a sand pile—but looks at them with a physicists’ eye, revealing a hidden elegance in mundane physical mechanisms. In six chapters—Builders, Creating Shapes, Building with Thread, From Sand to Glass, Matter in Motion, and Fractures—the authors present brief stories, set in locales ranging from the Eiffel Tower to a sandcastle, that illustrate the little wonders hidden in the ordinary. A simple experiment that readers can perform at home concludes each story. More than 200 illustrations bring the stories to life.
Through these stories and images, the authors explain the amazing mechanisms that govern the elements that surround us, offering a close look at the subtle dialogue of form, force, and function. They connect the underlying physics to a range of applications: crumpled graphene sheets that may be used in batteries, wet-hair physics that must be taken into account in the manufacturing of mechanical microdevices, pine cone mechanisms used in contemporary architecture, and more. Each chapter offers striking two-page spreads of text and images.

How everyday objects reflect deep and beautiful mathematics and physics. You'll never look at a bubble, a spider's web, or a wineglass in quite the same way again. Utterly fascinating!
Ian Stewart, author of Do Dice Play God?, Calculating the Cosmos, and The Beauty of Numbers in Nature
Hidden Wonders is a lovely reminder that amazing science needn’t be exotic or remote, but surrounds us every day with riches at the same time reassuringly familiar and constantly surprising.”
Philip Ball author of Patterns in Nature, Beyond Weird, and The Beauty of Chemistry: Art, Wonder, and Science
From why things break to why they hold together, from why cut flowers wilt to why arches can stand for centuries, from the drape of a necklace to the strength of sea shells, Hidden Wonders is endlessly entertaining and enlightening. With clear prose, engaging illustrations and kitchen-table do-at-home experiments, this fun and accessible book will give you a new appreciation for the wonders of the world—both natural and man-made—that surround us every day.
James Kakalios Professor of Physics, University of Minnesota; author of The Physics of Superheroes and The Physics of Everyday Things

ZigZag cover of Advanced Materials

Many active materials used in shape‐morphing are capable of stretching or contracting along a director field. In article number 2004515, we show that texturing this field in zigzag patterns provides an extended family of deformation, opening a larger parameter space for shape control. This concept can be applied to any anisotropically responsive material.

(Soft Matter cover): Programming stiff inflatable shells from planar patterned fabrics (2020)

Emmanuel Siéfert, Etienne Reyssat, José Bico and Benoît Roman
Origami-inspired design of Gaussian morphing fabrics structures. Superimposed flat and inextensible fabric sheets are heat-sealed along a specific pattern of lines. Upon inflation, this network of tubular cavities deploys into a large, stiff and light shell, with a programmed shape.
