It is well known that cables love to tangle. Everybody knows that, everybody who ever has had to do with cables. Yet nobody knows why they do tangle. And everybody should know it, because this is the matter fundamental for the world.
Now all the scoffers and jeeres will start mocking: what an anachronic problem, now, when the world is getting wireless? it's a sheer waste of time and energy good for tangled minds and meshed brains.
Well, it's not a waste of time and energy, not at all. Because it's not true that the wireless world will be less tangled than the wired world. Besides cables and wires we have lines (and links), ropes, strings, stripes and ribbons, paths and tracks, threads, chains (including DNA), and plenty of other wire-and-cable-like things, matters, affairs, phenomena (languages, thoughts, sentences, phrases, melodies, strokes, tails, ponytails, pigtails, braids – just to mention a few). And it's good to know that no-wires and no-cables (wirelesses and cablelesses) can get tangled, too.
So, the issue is of unprecedented importance and it should be neither discarded nor postponed.
But why? If cables and wires keep tangling all the time it has no sense at all to try to untangle them. Has it any sense to gather knowledge which can not be used for any practical purposes?
This is a very good question, indeed, and this department will try to answer it. Right now, at the very beginning, it should be emphasized that we never know what and when will or will not be used for. Besides, some people like to know, while the others don't. It's quite easy to answer the question why some people like to know while the others do not, but we won't take this problem under consideration here. Because here, in this very case, the situation is different. Everybody, or almost everybody (a lousy scoundrel who doesn't want to know what all the others do can be found everywhere) wants to know whether cables tangle themselves or are being tangled. And if they are being tangled then who or what or who-and-what tangles them. These are questions which make our blood pressure higher, take the sleep away, don't let us think logically. Therefore the problem should be studied extremely carefully, with no emotions. And systematically. And chaotically as well.

Methodology of studies

Of course the FTC will focus both on theory and practice. This is clear. The students will practice both tangling and untangling. And prevention – how to avoid tangling, and how to cause tangling. And so on. And the theory? Oh, the theory. Its range seems to have no limits…
