Can anybody tell me how my carefully placed headphones are always tangled whn I take them out of my pocket?

Pic related.

Entropy bro. It always increases.

cuz of earth rotation

I know the pain OP,
I have the worst luck when it comes to tangles

Entropy turns it from a neat coil to a cluster of wires?
How?

Heaps of string will inevitably get tangled under mechanical agitation (such as in your pocket), so long as the ratio (rB)/L is under a certain critical value, where r is the radius of the "string," B is its bulk modulus, and L is the length of the string in question.

Clearly the tangle coefficient is small for this string.

There exists infinitely more disordered states than ordered states for the wire. Thus any random event which can change its state is predicted to put it into a state of disorder.

>> No.1948969

There is 1 configuration that is in order.
There are infinite chaotic configurations.

But there also exists an infinite number of ordered states.
Are you >implying that one infinity is larger than another?

Both of those are large but finite , not infinite. You never reach anything infinite (as far as we know, exception maybe the interior of black hole) in our universe. The number of particles in finite, and there is a finite number of possible configurations. And we most definitely do not reach any kind of infinity larger than aleph_0

Anal faggot above pointed out that there are finite ways of entangling the wires, not infinitely many. So let's say "virtually infinite" to please that pedant pederast. Well, it is true that there are virtually infinitely many ordered states, as you say. (BTW, all of those states are materially equivalent to each other, because as long as the wires are not tangled, you're happy. But that ain't the point.) But once in any of the virtually infinitely many tangled states, it may take many "steps" to get back to being untangled. From an untangled state, however, it is relatively easy to get into a tangled state. I think that was the point.

>>1948971
You are clearly an idiot if you do not plainly see that there are many more unordered states than ordered ones.

Also worth noting is that OP wouldn't prefer just any ordered state, but one specific family of ordered states, namely unentangled cables.

Desirable states are a minute subset even of ordered ones.
