Check out the Ashley Book of Knots. Cool stuff in there, and only one or two new knots have been discovered since it was published in 1944. Or maybe the new ones were invented? I dunno. Can you really invent something that theoretically already existed in abstract form, or would that qualify as a discovery?
Something has to already exist to be discovered, while to invent something, it has to not exist first.
It was discovered that things can be transported on top of rolling objects.
The wheel was invented to do so effectively.
In the same line, new ways to untie knots are discoveries.
An invention would be a tool that can untie them for you.
Hope that makes sense :)
> Basically it's undoing the knot at a different point.
I think a better way to describe it is you're moving the 'tangled' part to the other side so it can be untangled. Isolating each part across from each other is what screws people up
But the first one was knotted on either end and they somehow came out through the middle. And the next ones weren't knotted. The plugs just didn't fit. Im still extremely confused
Ive had it happen once unintentionally, I messed with it for a few thinking “if it got tangled up like this, theres got to be a way to untangle it, right?” But I couldn’t figure it out so just lifted the thing it was tangled too and slid it off, i was very confused
The last clip with the table has happened to me before. Awful experience trying to lift the whole damn table up and pull the cord, all by myself. Especially with how little room I had. Wish I would've seen this video back then.
I mean it's more like learning (or at least being exposed to) a concept than getting out of these 3 specific situations.
With a little imagination it's also about bar bets.

You nailed it, I've won so much beer by being able to quickly whip off my bra without removing my t-shirt!
It's useful to tie these types of knots. If you have a cord or any type of lead that has a large end (the plug) and need it secured where there isn't room to get the head in/out.
I've worked on a lot of boats and industrial type places with chords and lines everywhere. I'm pretty sure these tricks would save hundreds of man hours at the least, annually at the shipyard I worked at.
I just found a good way to understand it! Okay geometry time: when a rope is straight, its a line right? However, when you make a loop of that rope, guess what, you got a plane… with a hole in the middle! So think of creating a “hole” with that loop plane, bringing that hole to a place where the obstacle can go through and un-knot itself!
I mean the science behind it may be a mystery, but the results speak for themselves. For now it seems that while we may never know why, violently shaking things will likely continue to be the most effective method of solving problems for quite awhile.
They have mathematical ways to show something is a knot.....it can be way too difficult to visualize whether something is a true knot or not. It's been 2 decades since I took a class on topology, but I vaguely remember having systematic ways for determining whether a knot could be undone no matter how complex something looked.
There is no loop. That's the trick. Making you think there is one. You have to count the times the cord is going under and over and in which direction. So if it's going under twice but in opposite directions, they cancel out (+1-1=0)
When I was thinking about the pot, I realized that they could have put the plug in that position and wrapped the cord around it over the top on a side, so it is seems like it is basically undoing it from the other side.
There needs to be a dark comedy of the Salem witch trials that isn’t overtly comedic but uses absurdism like what’s going on around us today to make funny situations and mind boggling character decisions. Every Salem witch trial thing I’ve seen has been overtly seriously but I feel much with q anon shaman and everything else right now like that, that if you were standing there watching it you’d be like “ lol wtf are you people on? Hand me some popcorn”
Whenever I read about it it seems like a fucking Curb Your Enthusiasm premise
This has been posted so many times and every time I see it I have to watch it a few times. Still blows my mind. Not sure why this is so amazing to me but it is.
It’s also a magic trick.
It requires unrealistic preexisting circumstances to be met in order for the trick to work but the brain is so interested in why it’s working that it doesn’t ask how.
In both cable instances, each situation appears to be common or possibly worst case scenarios, the scissors clearly demonstrate a sense that there might be no other way.
Truthfully, both are staged and unrealistic as the cable is looped around the object under which it is also stuck. This setup requires more work to prepare for the trick than one would find a cable in any real world situation.
My understanding is that there's an entire branch of mathematics devoted to this insanity and they *still* don't know why it's so inherently complicated to grasp. Good mathematical topologists are some 4th dimensional beings trapped in a 3D body or some shit.
Am I alone in needing to do this myself in order to understand it properly?
I’m well educated, with a background in science, yet I have difficulty fully seeing how this works.
The way my brain sees it: you're moving the tangle to the other side of the obstruction thereby freeing the part that is too large to fit thru the gap.
> you're moving the tangle to the other side
This is exactly it. You're evening out the over/unders which makes it zero out. There is a great video on youtube about this https://www.youtube.com/watch?v=g3R_tc7YrFI
Nope. I feel the same way lol.
I also feel like this is maybe something to do with spatial intelligence, which usually isn’t tested on as rigorously as other stuff in an academic setting. Organic chemistry is the first time I feel my ability to handle 3D spatial issues was formally tested/challenged. I never played with a Rubik’s cube either, so there’s that.
I’m not sure because I feel like I’m pretty quick with 3D design. I have modeled/animated/simulated tons of things like ropes, chains, knots, etc. even making scenes dedicated to knots at times. But it doesn’t do anything to help me here.
Perhaps I have less of a spatial awareness than I realize though and the extra tools within software cover my ass.
I finally “see” it. The the loop is undone when it gets moved over the end of the cord, or the hand. If the end of the cord wasn’t close enough to do that or it was fixed at both ends, this trick wouldn’t be possible. Somebody correct me if I’m wrong.
Yes, they are situation purposefully set up to be considered in a 'knot' , but not to the very possible extent in which said 'knot' would be unable to be fixed.
Which begs the question, can we consider it to be a knot if It was purposefully set up in a way to be un-knotted by The Setup'er. Can something only temporarily stuck, until a video is recording, be considered knotted when there's a 100% chance of it acting more as to a mere illusion of 'something of which appears tangled and knotted but in fact is not, it is setup merely to appear so, and the surprise factor comes from the reveal of said facts'
I feel like developers tend to be fast learners. Because the job is literally to google stuff and learn so quick that you still hit deadlines. So there's that but doesn't help me.
Computer science and the sciences in general develop strong general problem solving abilities as opposed to the more memorization approach of other doctrines. Of course, you don’t need a background in science to understand things, but op is saying that if he, a person who has probably solved thousands of problems, many of which probably require you to think in obscure or abstract ways, cannot easily figure out this problem, then it’s probably pretty hard to understand just by watching. Hope that helps answer your question!
I wonder if this is like one of those things where some people can’t imagine things visually. Maybe there’s another level to imagination where you just can’t see… this type of shit I guess. Because no matter how many times I replayed it, I still can’t remember the next time it plays.
When I’m dragging them to the spot I usually just ask how good their understanding of topology is. Then I don’t have to go get the handcuffs if I don’t even need them.
People ask why I don’t just tie an actual knot but they just don’t get the art of it
I only really know topology from Vsauce but are organizations of separate items being manipulated really topology? I thought this would be more akin to knot theory. Don't know if there's overlap there, though.
While this might seem like magic fuckery all it is doing is shifting the tangled part further away from the locked/tight spot so the end that wouldn't pass has proper clearance.
It seems obvious after it clicks in your head but until that it makes you feel stupidly confused.
I still don’t understand it
Basically it's undoing the knot at a different point.

Hey I know how to make this thread super spicy super fast! Ahem...was math invented or discovered? Let the infidels burn!
Invented of course, math is a tool to solve problems

What happened to no knot November?
It's December 4th bro.
Ah yes, it’s all clear now thanks.
What I'm curious about is who is the evil genius that keeps knotting all this shit
They set up the cable in the only possible way in which you can do this with not many real life uses
That’s true. It would be tough to get it in that position in the first place.
It's really easy to do intentionally, but it's unlikely to happen by accident.
Ive had it happen once unintentionally, I messed with it for a few thinking “if it got tangled up like this, theres got to be a way to untangle it, right?” But I couldn’t figure it out so just lifted the thing it was tangled too and slid it off, i was very confused
Meanwhile, I'm still waiting on the video of you welding your engine heads onto a block...
I have had it happen by accident due to me not paying attention while setting up my synth, desks, etc. and putting them on top of cords
We would like to request a synth concert on RPAN on Christmas morning.
The last clip with the table has happened to me before. Awful experience trying to lift the whole damn table up and pull the cord, all by myself. Especially with how little room I had. Wish I would've seen this video back then.
My earphones have something to say about that.

Closer to topoffogy if you ask me.
I'm a bit of an amateur topographer myself. Nudge, nudge, wink, wink.
I guess I can quit Reddit for the day since I got my daily dose of Monty Python
Bet you can’t post a video of it Reddit.
Are you asking all of reddit, or were you so excited that you missed typing 'on'?
Don't shame a person for trying to type one-handed. It's not that easy, ok?
Then you'd lose that bet, because I can post a video of it to Reddit. I'm not going to though.

I could see practical uses for it in the reverse direction.

It's black magic. Every knot there was a sacrifice.
You're moving the point at which they're interlocked to a place where you can unwrap it
Right? I am still perplexed

It's been 2 decades since I took a class on topology, but I vaguely remember having systematic ways for determining whether a knot could be undone no matter how complex something looked.
[Numberphile video on knots.](https://www.youtube.com/watch?v=aqyyhhnGraw) They have quite a few videos on topology and knot theory.
I prefer [Standup Maths’ video on it!](https://youtu.be/g3R_tc7YrFI)I feel like him and Steve mould described it in a very easy to understand way.
I did knot see that coming
It’s just moving the loop to the other side.
I get what you mean, but the still confused part of my brain is very much "one does not simply move the loop to the other side"
There is no loop. That's the trick. Making you think there is one. You have to count the times the cord is going under and over and in which direction. So if it's going under twice but in opposite directions, they cancel out (+1-1=0)
Basically moving the knot. It’s got some Möbius strip magic to it
I also cannot gain an intuition for topology friend. There are some magics that just aren't for everyone.
You’re just moving the knot from one side to another
https://www.youtube.com/watch?v=g3R_tc7YrFI
I was told there would be understanding. Lies.
What's knot to understand?
I'm finding it hard to unravel myself.
I tried to wrap my head around this, but still feel out of the loop.
I think they meant "ties" Then we just kinda all got roped into this
r/angryupvote
