Human beings have been tying knots for thousands of years, and we've gotten great at it. Now, scientists are finally starting to explain why some knots hold and others don't.
Knots, and the fibers and ropes they're made from, are ancient and sophisticated technology that most of us take for granted.
… inventing knots seems to be a uniquely human activity and that such complicated knots don't appear in nature.
"The question of how did people even come up with these knots kind of baffles me," says [Vishal Patil, a graduate student at the Massachusetts Institute of Technology whose new findings appear in the journal Science].
