Origami describes rules for creating folded structures from patterns on a flat sheet, but does not prescribe how patterns can be designed to fit target shapes. In an article in Nature Materials*, Prof. L. Mahadevan and colleagues from SEAS and University of Tokyo describe their use of origami folds, or tessellations, to program curvature for creating various pop-up objects.

What The Physics?!

January 22, 2016

Harvard Physics grad Greg Kestin (PhD 2014) has published the first video in a new "What The Physics?!" series. Each episode will explore 'something surprising or really interesting related to physics. Like the science behind the movie "Interstellar," or exploring what real parallel universes might be like… basically, things that make you go, What The Physics?!'

The first episode demonstrates an effect of one tablespoon of olive oil on half an acre of waves on a lake.
