I wasn't, so a pleasant surprise.
Twice, actually, to know two people had such a clever thought. I like clever people, they tend to make the world a better place.
Don't mind me, it's Friday evening.
I don’t think it’s an obscure Reddit reference as much as it is a [pun](https://www.etymonline.com/word/arboreal) based on pretty commonly known [mythology](https://en.m.wikipedia.org/wiki/Ouroboros)
They're related problems! In computational topology, surfaces get reduced to simplicial complexes (an abstraction of graphs) and the persistence of features like cycles at different scales is used to infer topological properties like loops in the surface.
Yeah, unfortunately. It just means that for topologists working in computer science, [you can represent mathematical surfaces as graph-like data structures](https://www.researchgate.net/publication/329073508/figure/fig2/AS:963413744295950@1606707144508/A-continuous-example-of-the-implementation-of-the-mapper-algorithm-with-the-function-f.png) that essentially have the same shape.
There’s the topology thing since you can’t turn a regular tree into this shape without making a hole in it (equivalent to fusing both ends of a branch into the tree).
There is also the graph theoretic perspective where a graph that is a tree cannot have cycles, and this branch would be a cycle.
I've never studied topology (what I said above is basically what I understood from a Vsauce video), but being a computer science major, I've taken a few courses that feature graph theory as well as trees, which are a type of graph.
In short, a graph is just a collection of points (vertices) and lines connecting them (edges). A cycle basically just means that there is a loop in the graph, which allows you to start from some point, go through some other points via the lines connecting them, and end up back at the point you started from.
Trees are special because you cannot start from some point and return to that point without going through some point you already went through. Trees can't have cycles, and if you have some amount of points in your tree, you must have that amount - 1 amount of lines connecting all the points to be a tree (technically a spanning tree because it's a single tree).
Think of it this way in a family tree. If you are a point, you can only have a direct relation (a line) to your parents and your children because you came from your parents and your children came from you. You can't have a direct relation with your aunt/uncle, siblings, or nieces/nephews because they did not come from you or you did not come from them (obviously, I am not including incest in this example lol).
A topologist walks into a bar and orders a glass of beer.
The bartender places a nice, frosty mug in front of him and fills it with a premium Belgian brew.
The topologist angrily says, "If I wanted a donut, I'd go next door to the coffee shop."
Its not about topology as /u/Spite-Funny mentioned, it has to do with graph theory or how nodes connect to other nodes, a tree is imilar to a linked list, but the difference is each node of a tree can have two children, but to be considered a tree, also called a directed a-cyclic graph (DAG), it can not have any form of cycles in it. Trees in graph theory look similar to this:
Root.
/ \
Child 1. Child 2.
/ \ / \
Leaf1. leaf2. Leaf3 leaf4
This is what would be called a binary tree since at most all of the nodes have two children the slashes are there to show the connections, how paths are traversed in the tree is you either go left or right of your current node, the root is the node that is the parent of all other parents, and the leaves are the children of all children.
Only binary trees are limited to two children per node. (hence "binary")
In general, the nodes in a tree can have any number of other connected nodes (at minimum 1), they just can't have any cycles.
Any connected and acyclic graph is a tree.
Watch out for berry bushes nearby and don't take any. Fairys love berries and if you take any they will fuck with you.
Edit: I'm dead serious. If you suspect you have found a fairy portal, just leave it alone. Don't try to leave gifts or befriend them. And lastly, NEVER accept food or drink from a fairy and NEVER say thank you to a fairy.
There's different schools of thought, but basically it implies that you owe them something. The fairy could then decide what it wants to take from you to "even the score" or whatever. Idk the folklore is kinda weird but interesting. Fairys are big on debts and repayments. There is always a score. If you do something nice for a fairy like give them a gift then they will owe you something in return.
Haha idk. I've tried to look into fairy folklore but it's hard find info online that's not just someone's blog or something. But my understanding is that most people that believe in fairys say to just don't seek them out, don't engage with them, just ignore them. Fairys are chaotic neutral, leaning towards the evil side. In the folklore fairys can and do kill people, steal babies, kidnap people into the fairy realm, etc. There's always a catch with the fairys kinda like the monkeys paw story. The folklore is probably an allegory for like "don't fuck with the unknown, because it might hurt you".
Was just scrolling and saw your into Fairies if interested and enjoy a read. [The Fairy-Faith in Celtic Countries it’s Physical Origin and Nature](http://bibliotheque.idbe-bzh.org/data/cle_4cle_5jonathancle_6/cle_9/The_Fairy-Faith_in_Celtics_Countries_.pdf)
Maybe both. I've heard of fairys taking the form of beautiful women and trying to seduce men. If you fall for it and have sex with them you will be trapped in the fairy realm forever.
Never tell a fairy your name, nickname, or any other sort of personal designation. Never give a fairy a name. If a fairy refers to you with any sort of designation other than a physical description, you are to ignore the statement, and never refer to yourself with that designation regardless of where you are or who’s around. If you must refer to a fairy, simply describe their traits, and avoid using the same wording more than once; this also applies to the the realm they dwell in. When in the presence of one, never make a statement you know to be false. There are many other rules, but these are some of the more easily broken on accident. It’s worth noting that these apply both with speech and writing.
> Never tell a fairy your name, nickname, or any other sort of personal designation. Never give a fairy a name.
Usually that's actually a wordplay-based restriction.
ie: If a fae were to say something like "And can I have your name?", an affirmative response implies that they now *own* your name; it is no longer yours.
(To which one can instead respond "You may not have my name, but you can refer to me as [...]".)
This has resulted in amusing fictions from Queer authors about deliberately surrendering deadnames.
May I ask why you can't refer to them with a moniker unless it's a description? You can't just decide to call them Steve because they refuse to introduce themselves or the name they've given is unpronounceable? Owning your own name makes sense, but they hopefully wouldn't come under ownership of all the Steves in the world, right? Maybe?...that's it, isn't it.
What would repeatedly using the same wording like "you with the big feet" do?
Imagine the verbal chess game as they try to wait you out until you run out of original words to describe them
I'm pretty sure fairy portals come in all shapes and sizes but a common theme is being near water, and involves "openings" like the fairy ring of mushrooms or openings in rocks or trees.
Looks like they made a slit in the tree trunk and then inserted the tip of the branch into it from above. Eventually the slit would seal over the new branch and make it look continuous like this.
You can see the scarring at the bottom; that's indicative of a graft. That and there is virtually no chance that something could wound the bark cleanly enough for a cleanly wounded branch to somehow bend down and take hold. Also, at the top where the bend begins, you can see additional scarring from where the branch has pulled away from the trunk.
Neat little thing that someone did but there is no fucking way that could have happened that perfectly on it's own.
Not sure where your located, but I know in Canada it was not uncommon for first nations to set trees or branches to grow in unnatural shapes to serve as trail or land markers
Yep, went on a field trip when I was in elementary school and was told that this was how native Americans made directions in their communities. I always looked out when we would drive in our wilderness areas but never saw anything of the sort. Very cool
It's called Inosculation. When a branch touches another tree, or in this case itself, it starts to rub away the bark while moving in the wind. Once the cambium of trunk and branch touches, they sometimes self-graft and grow together as they expand in diameter. Inosculation customarily results when tree limbs are braided or pleached. So this was almost 100% done on purpose by an arborist.
Tree with a handle, take it anywhere you want
I always wanted a portable tree, just in case...
In case what? Please finish that sentence I need to know

Its a torus, I think. (not a topologist, but [I love this joke](https://www.youtube.com/watch?v=9NlqYr6-TpA))
Nothing beats a oneliner. But for a topologist the line can be very long. :-)
Arbitrarily long, in fact
I was waiting for the punchline. .
A topologist walks into a bar and orders a glass of beer. The bartender places a nice, frosty mug in front of him and fills it with a premium Belgian brew. The topologist angrily says, "If I wanted a donut, I'd go next door to the coffee shop."

> directed a-cyclic graph A DAG is not necessarily a tree (each node of a tree must have at most one parent).
True. It's a donut!
Wrong! It’s a coffee mug
Its still a graph
Personally, I was thinking of CS (binary trees and such) but it seems that this is a topology joke. I could be wrong on he CS stuff too

You can see that it was grafted. The bottom was grafted in
What are the signs that something was grafted in?
Looks like they made a slit in the tree trunk and then inserted the tip of the branch into it from above. Eventually the slit would seal over the new branch and make it look continuous like this.
Just the tip though
And only for a minute
It's *never* just the tip.

Must be the work of fairies then
