"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 soft, lifelike robots.
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.

"Right off the bat, they found shoelaces didn't untie when a oerson just swung their foot nor when they only stamped the ground."
"The team acquired a high-speed camera and pointed it at
Gregg's shoes as she ran on a treadmill."
"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."
"This result suggests laces made from heavier materials may be more prone to screwing up, because unless you're phenomenally gifted at tying even knots, one free end will likely be longer than the other."

The sentence that contains information that should be left out of an abstract is:

"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."

This sentence provides background and context about the researcher’s personal motivation rather than focusing on the research findings or methodologies relevant to the study, which are more appropriate for an abstract.
