Almost all people have encountered this problem: If you put the headset in your handbag, you will always find the headphone cord knotted the next time you use it. It's almost easier than the hair of Rapunzel. Nothing is more annoying than this problem! Fortunately, today, scientists have found a simple way to prevent the headphone cable from tying knots: connecting the two ends of a line to form a loop can greatly reduce the chance of knotting.
"Cyclic conjecture" reduces knotting British scientists have recently discovered that linear objects are inherently knotted, and that the longer the lines, the easier it is to knot. Fortunately, they have studied how to avoid tying knots with linear objects. By connecting two ends of a line together to form a ring, the probability of tying the knots can be greatly reduced. Scientists call this discovery a "circular guess." ".
Matthews led his colleagues in an experiment where they bundled various lengths of ordinary packaging tape and counted the number of knots of various lengths of tape. After repeated trials, they can figure out the probability of knotting problems for a particular length of tape.
Then, the scientists connected the two ends of the tapes together and conducted the same test. As a result, it was found that the tying of the packaging tape was greatly reduced. Later, in a school in Coventry, they conducted a similar "circular conjecture" experiment, allowing children to conduct 12,000 knot tests. The children also came to the same conclusion.
On the surface, the meaning is by no means so simple that the headphone cord is not tied. Their research has aroused the interest of biochemists because biochemists are also investigating the tendency of DNA strands to knot themselves. Recent research shows that nature may have built some cycles in DNA to avoid DNA knotting. Also constitutes a headset is not easy to knot.
