"Archer's Knot": https://www.youtube.com/watch?v=vXu3NgWHMvA
A really handy knot where the loop stays fixed /w tension on the standing end, and the working end can be cinched to shrink the loop.
Fun fact: this knot seems to be the complement of the Arbor Knot (https://en.wikipedia.org/wiki/Arbor_knot), where standing end tension cinches the loop & the working end doesn't.
Also, handy rope terminology that really helped me out: https://www.ropebook.com/information/knots/terminology/
@vanillacherry I was really intimidated & confused when I first started. I didn't realize that it took time for my brain to learn to "think in knots". So don't be off-put if it's frustrating at first, if possible!
I started with this cute little book: https://www.amazon.com/Why-Knot-Ingenious-Beautiful-Lifesaving/dp/1419706764
I used this as a reference frequently, or just to look for something new to try: https://www.animatedknots.com (if you search for any knot from here on youtube you'll likely be able to find a variety of videos done differently that'll help it *click* for you).
When I see a knot used in practice & ask its name (or maybe it's on tv and they say it), I'll look it up and see if I can reproduce it. I don't find "tying knots for the heck of it" very interesting -- it's when it has a use in my life that it gets exciting!
Over time you'll start to build a "knot knack", where you begin to see all sorts of daily situations where rope + knots could be used to solve your problems.
@vanillacherry Try to keep on building your inventory of knots! The more you know, even if you still need to look it up each time for a while, the more you'll spot applicable situations for them!
@tty I've wanted a not that behaves like a logic gate or opamp for a long time, does something like this already exist ?
(also is there one that'd let me quickly join / unjoin two ropes without having to look at them ? that'd be perfect for holding my glasses on)
@bx Can you clarify further re: logic gate?
Re: join/unjoining ropes (these are sometimes called "bends"), hmm, if it just needs to hold a light load like yer glasses, just an overhand knot with the two strings together is simple enough to do by feel (I just tested this).
So, you'd do this fella (https://www.animatedknots.com/overhand-knot) but put the ropes side-by-side and tie it like it was one rope, if that makes sense.
@tty I mean some kind of knot of one or more pieces of rope that could have 3 bits comming off with 2 inputs and 1 output, applying tention on the inputs would affect tention on the outputs, for example an AND knot, would only have tention on it's output when it has tention on both its inputs
@bx Hmm. It's an interesting question! I'm not even sure how to imagine what this'd look like!
Like, when you say "have 3 bits coming off", what does that even mean?
@tty either 3 ends or 3 loops i guess, i too find it kinda hard to visualise, i think i'd need some kind of static frame to tie it around,
essensially i want to build a rope computer
@bx I think the key at this step is to figure out how to formulate what bits and inputs and outputs mean exactly re: ropes. Another difference between a flow of electrons (and even flowing water) is that for a given knot, when tension stops being applied, knots don't generally loosen themselves back up, so the presence of a tightened knot doesn't imply that the bit is flipped on, just that it was *at one point* flipped on.
@tty I was thinking that could be resolved by having an extra "power" input to all gate knots, the power input always has tention, and the knot could use the power tension to reset it self to a "ground state" somehow.
(i would love to keep talking about this but i have to go to bed)
@bx I was thinking about that too! Each rope could have a weight on one end providing constant tension.
@kondziu I once had a girlfriend with a chain necklace knotted so badly that after days I still couldn't unravel it. So.. maybe!
@tty Ha! But it was tangled though. But could one design a knot that couldn't be untied? Or, like, make the rope wet to change its properties after the knot is tied, so that the knot would strength? Or separate the rope into strands and re-weave the end back into the knot?
Sorry, feel free to ignore all that. I never thought about it before and I got overly fascinated by the possibility of such actually un-untiable Gordian knots existing.
@kondziu Tangles are just complex knots!!! If everybody who tried untying it gave up, does that mean it's untie-able? :) What does that word mean to you in this context?
@tty I guess I mean physically impossible. Like, it's too tight, or some trick of geometry makes something latch into place.
@kondziu Not sure if that qualifies for what you're thinking of, but: synthetic rope likes to melt more than burn, so sometimes I do a quick permanent loop by using a lighter to melt the ends together.
@johan Yes! It can be handy when you have a horizontal rope going across something, and you want to add fixed spots where you can hook/hang things on it, so they won't slide around the rope.
I haven't tried this, but I also think you could make a simple little rope ladder by tying these alternating left/right along a vertical rope :)
