Fun Facts, wired earbuds

Fun Facts

If you wind the cord from your earbuds into a circle, they always get
tangled when you try to use them.

If you fold them over and over until they're short enough to put where
you want them, they unfold with much less gangling than the method
above. At least in my experience.


There must be some branch of science or math or industry that deals with
stuff like this. Anyone know?

it's called knot theory.

<https://www.sciencealert.com/the-mathematical-law-that-causes-your-head
phones-to-tangle>
But between 46 centimetres and 150 centimetres (about five feet), the
probability of a knot forming rises dramatically. With a cord longer
than that, the probability of a knot forming reaches a plateau of 50
percent.
...
"At least" because earbuds are, of course, a Y-shaped string, and
thus the knotting frequency is compounded further. (Raymer and Smith
didn't look at strings with more than one branch, but anecdotally I
can confirm that the tangle-rate is pretty high.)

I can tell you from long experience as a racing sailor, if you want to
ensure a halyard, sheet or other line runs free when you need it to, you
toss it into a loose pile; only making sure that the bitter end isn't
beneath the pile but rather off to the side.

Sure, we coiled lines for putting the boat away, but never when actually
using them.

Demonstrating once again how little you understand.

How things tangle is definitely a part of "knot theory".

"Spontaneous knotting of an agitated string"

<https://www.pnas.org/content/104/42/16432.full>

And from that:

"We used mathematical knot theory to analyze the knots. Above a critical
string length, the probability P of knotting at first increased sharply
with length but then saturated below 100%"

And here goes the circular argument again.

The subject was the tangling of earphone leads,

You were told the problem was not in the field of ergonomics, but knot
theory, and shown a paper describing the tangling problem.

You declared that tangling isn't a not.

You declared the paper had nothing to do with knot theory.

You were shown it did....

...and now we're back at the top.

I just showed you the paper that declares it is.

You don't have the slightest clue what "knot theory" is in the first place.

Maybe you should "roadie wrap" the cord?

Yup... ...I know that one well.

It's great for coiling a cable or anything else where twisting in only
one direction will cause the rest of the whatever to get progressively
more and more twisted; especially when you're dealing with something
very long.

What it won't do is prevent tangles when you uncoil it.
