"Science: Why Shoelace Knot Failure" by Nsikan Akpan Mechanical engineer Oliver O’Reilly began looking into this telltale problem three years ago, after trying to teach his young daughter to tie her shoes. “I went online and found all these helpful videos about how to tie your shoelaces,” O’Reilly said. “They were wonderful and very helpful, but I also noticed there were no videos online about why your shoelaces become untied.” This dearth of information pinged O’Reilly’s attention because he studies dynamics — the science of motion — inflexible materials for soft robots. While Disney’s “Big Hero 6” might look cool on the big screen, a lot of mathematical models on how and when materials deform would be needed to build such a robot. So, O’Reilly handed off this investigation into shoelaces as a side project for two of his graduate students, Christopher Daily-Diamond and Christine Gregg. Right off the bat, they found shoelaces didn’t untie when a person just swung their foot nor when they only stamped the ground.
