It's been a while but I want to say this is not a topological concept. Topologically the band with no twist and with a full twist are both just a disc with a hole, they're homeomorphic meaning topological tools can't tell the difference between them. A half twist (Mobius strip) is distinct though..

Still the argument I used is partly topological, cutting things apart and glueing them back together is very much of the subject. Anyway I believe there are math people on the sub who cracked a book more recently than 12 years ago, please chime in!

Edit: And now I'm realizing this is almost certainly wrong, for example knots are just circles no matter how convoluted but you can still study them with topolgy by looking at their complement, which would be the whole of 3d space but with the knot cut out, probably you can do the same with these bands. So correct answer would have been: I don't know

Yes, odd numbers of loops can always be made to work. If you glue a strip of paper so it makes a loop with a single turn you can twist it so it wraps around twice to lie flat. Notice that when you use a regular loop and pinch it you've basically recreated that scenario, you could glue it together at the pinch and cut off one side (see picture) and you'd just have a single loop with one twist, and you could repeat that process any number of times, each new twist crosses over in the opposite direction, undoing the twist previously created.

Digital release next month apparently, immediately there will be torrents https://www.inverse.com/entertainment/dune-2-digital-release-date

Yeah but more like 15 years, it's not great

From when the movie came out to four days ago I'd been unable to muster the motivation to rewatch deadwood for the first time but I found the time to try and watch every Star Trek show I haven't seen, fucking idiot!

This isn't likely the cause of your issue, think it was a previous version of windows, but a few years back Microsoft patched a bug that caused checking for updates to take exponential time in the # of updates to check, causing some previously offline PCs to literally just grind until theyre turned off or the sun expands to engulf the inner planets. Anyway bad performance on not freshly minted installations of windows is I can only assume a feature to them

I comfort myself with the fact that eternal torture is impossible because the number of distinct quantum states your brain can have, given that it can only occupy a finite volume is, while very large, technically finite. Eventually the torture will just loop around to the beginning so it's not really an eternity. The devil could try to just continually expand your brain so that you can experience more intricate types of pain but eventually your head will grow so large that it collapses into a black hole. They could try to make it very long and thin rather than roughly spherical to avoid this, but eventually the expansion of the universe will causally disconnect one half from the other. centrist

There wasn't much going on in the world, we passed the time posting about a subreddit about a podcast about the 2016 us election

It's from this I believe: https://reason.com/wp-content/uploads/2024/01/A-Tik-Tok-ing-Timebomb_12.21.23.pdf

I'm not going to read it but I believe they compared amplification of hashtags on tiktok to Instagram or something and found that "anti us" and "pro China" tags got more traction. Idk if that's deliberate, if so then good! But how do they know it's not Instagram de amplifying the same links and/or the userbase just being more, uh, based.

I know it doesn't seem like it but not all of them are the same, society isn't as polarized as it claims to be, it's an illusion! Okay cards on the table I've only convinced one lib to not vote Joe and they were family and they were already using the g word about gaza.. still I fancy myself a lib whisperer and am therefore hyper qualified to give advice so, what you need to do is become them a bit first, rotate your talent for disagreeableness into finely honed debate skills, squint your eyes and imagine the eggs benedict and mimosas they shove to you at the crack of 11am is harmless pizza and whiskey, now you're catching on good job

I don't care about confirming fantasies of insufferable and genocidal libs, they will believe these fantasies regardless. As to whether society can produce like a more effective version of Trump, idk I feel like it's not that hard. This hypothetical person doesn't have to match Trump's charisma, the bar is incredibly low, and they don't have to be that smart either, just smart enough to fill their cabinet with non-clowns.
