<\/iframe><\/p>\n<p>Over the past decade, Professor L. Mahadevan\u2019s Soft Math Lab at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) has helped establish how the ancient Japanese paper arts of folding or cutting can be used to inversely design structures that transform dramatically in shape and function.

This work asks a complementary question: What can be achieved when the basic building block is not a fold or a cut, but a linkage?\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Over the past decade, Professor L.
