(2 points) \science: why shoelace knot failure\ by nsikan akpan no matter how tight you tug, it feels like some shoelaces are doomed to come untied. fret no longer, as new research from the university of california, berkeley, has figured out the physics behind why the knots fail and why some shoelaces are more prone to the mistake. while the poetic inevitability of the slipup may provide comfort to those afflicted by wayward shoelaces, the research published tuesday in the proceedings of the royal society of london a may also provide clues for building better shoelace knots. research showed that a single kind of motion did not cause shoelaces to come untied. two graduate students began to study the effects of motion on shoelace knots. a researcher wondered about the science behind shoelaces coming untied. it is a combination of the two main movements used in walking that leads to shoelace knot failure.

Explanation:

First, a researcher had a question about shoelace - knot science. Then, two graduate students started the study. Research showed single - motion didn't cause untying. Finally, it was found that a combination of walking movements led to knot failure.
