Now researchers have unraveled the mystery behind how such knots form. Two physicists used string-tumbling experiments and mathematical models to create a step-by-step recipe for knot formation ...

which differ from real-world knots in that they have no ends. You can think of each one as a string that crosses over itself a given number of times, and then reconnects with itself to form a ...

Through experiments, they have learned there are many interesting ways to explain the science of knots. In 2007, researchers at the University of California, San Diego tumbled pieces of string ...

It involves the study of mathematical knots, which differ from real-world knots in that they have no ends. You can think of each one as a string that crosses over itself a given number of times and ...
