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.

“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 personal background information rather than essential research findings or conclusions, which are typically included in an abstract.
