American Association for the Advancement of Science (AAAS)

Caption

A video of a figure-eight knot in a mechanochromic fiber being tightened. Angles of illumination were restricted, leading to the reflection of bands of color along the centers of the fiber (from the perspective of an observer). This material relates to a paper that appeared in the Jan. 3, 2019 issue of Science, published by AAAS. The paper, by V.P. Patil at Massachusetts Institute of Technology in Cambridge, MA, and colleagues was titled, "Topological mechanics of knots and tangles."
