I have a wired, landline phone at work. The wire from the phone to the handset is constantly twisted, and moreover, it’s not even convenient to talk. There is no technical possibility to change the wire. I want to know why the wire is twisted and what can be done to prevent this from happening?
I was also very worried about this issue at one time. When I was on duty as a communications and telephone company in one large company. I found that this happens with certain (more than half) employees. They regularly carry out the following actions in the process of work:
- Accept an incoming call by picking up the receiver with your right hand.
- After talking a bit, shift the handset to your left hand, grab a pen with your right hand and write down information.
- When you’ve finished talking, hang up with your left hand.
- After some time, sincerely perplexed - and why is this wire from the tube twisted again so that it is impossible to use.
The wire from a landline telephone is standardly twisted at the workplace! This happens because different people use it. In this case, one person, putting the tube in place, automatically often rotates it 180 degrees clockwise, twisting the wire in this direction, and the other person does the same, but in the opposite direction. But the same person can succeed. Especially if access to the phone is possible from different directions. It would seem that if many times completely randomly twist the wire clockwise or counterclockwise, then it should not twist. In fact, this is not so - the more the phone is used, the more the wire TURNS ONE SIDE! This fact has a rigorous and fairly simple mathematical explanation. It was first applied to the chaotic movement of molecules. This is the “random walk problem,” and the comic name is “the drankard's walk”. The problem was solved at the beginning of the twentieth century by Smolukhovsky and Einstein. A molecule (or a Brownian particle), randomly wandering, with time moves away from its initial position farther and farther. To prevent this from happening, you need to periodically unwind the wire (with the handset off), without waiting for such a twist at which the length of the wire is greatly reduced. But you can still unwind, starting from the end about from the tube. Only time can take a lot.
