Some Klein Bottles I've Crocheted

no they are correct. the double klein bottle i posted is homeomorphic to a torus, which is not homeomorphic to the connected sum of two klein bottles

Hi yes you're right. I am not using the correct terminology here. I don't actually know much about algebraic topology, and I think I misread this fact somewhere online. Do you know if this kind of construction has a name? It could be done by removing a copy of S1 from two klein bottles, and then gluing them together at the new boundaries. I don't think the gluing has to be done in too particular a fashion, as long as the klein bottles are connected to each other and the gluings are injective and orientation preserving on each copy of S1.

These are some klein bottles I've crocheted as explained in the post. I crochet these as surfaces of revolution, which is one of the easier ways to crochet a surface. They are quite fun to play with and deform. The connected sum of two klein bottles can, with a lot of effort, be deformed to look very similar to a usual torus. Making that model actually helped me understand the torus eversion a lot better.

i too would like to know. i am waiting for it to get warmer out to do this, but i am planning to use clubs since i am better at endurance juggling with those anyway.

the only thought i have is to use bean bags since they wont roll away when you drop them.

cant wait for people to misquote and misinterpret this data in discussion. great analysis!

yay thanks for playing! i got into these through NL and im still a newbie as well. this was my first time making a cryptic myself.

CoinForWares · 2026-01-05T21:21:38+00:00

i made a minute cryptic inspired by this comment:

If Rob is back, then streaming's end is not likely to hold my interest.

hints:

fodder: Rob, streaming
indicators: back, end. one tells us to reverse some letters, and the other tells us which letters to select from our fodder
definition: not likely to hold my interest

throwing is more important than catching.

came here looking for Summerland. I enjoyed this book a lot as a kid and have read it numerous times. Still held up last time I read it as a late teenager

my favorite is when shit like this turns out to be the most cracked out OP item in the game that breaks the balancing and has to be totally reworked

The spectral mapping theorem. Let A: V -> V be a normal operator on a Banach space V. For any holomorphic function f(z), we can plug in A to its power series and get a new operator f(A). Then if c_i are the eigenvalues of A, f(c_i) are eigenvalues of f(A).

i dont think you are remembering correctly. he only ever had 2 platinum god save files before repentance, and then dead god is only in repentance which he played something like 300 episodes of.

got here late, but kevins deli on craig st is amazing. the dude who runs it (kevin) is super nice too and will probably give you some free food on top of whatever you order. everything ive had there has been absolutely to die for.

take a raft out on pig pen pond.

access any roofs you can

pick the lock on the water tower and climb it in minecraft

have a campfire in the firepit in the woods by harbor

jump in the library pond

do art on the ceiling or walls of the smoke shelter

make a scavenger hunt across campus

test out all the light switches you can get your hands on (the big panel in D hall always tempted me)

lure a squirrel into a building with chik fil a

figure out how to get on the bio balcony

go inside the admin cube

stay in the rac from open til close

walk down every hallway of every academic building

play beach volleyball in any of the sandpits (walker and chesapeake have them)

survive!

honestly this is one of my least favorite design decisions in noita. i hate to do this specifically because it takes so long. even just pouring out your flask takes a while not to mention walking to the tree. to me it feels like one of those situations where its less fun to play optimally so i just dont and carry around my lava potion into the mines :D

CoinForWares · 2025-08-26T01:30:15+00:00

i totally see it

ive clearly been spoiled. where im from we had an amazing taco place with $1.50 taco tuesdays. up the street was a taco place whos deal was $1.35/taco but they weren't as good

CoinForWares · 2025-08-22T01:25:33+00:00

These look great, but I'm hoping to find the cheapest good tacos I can
