Editing Talk:2740: Square Packing

<!--Please sign your posts with ~~~~ and don't delete this text. New comments should be added at the bottom.-->

I suspect Randall saw the same social media post that I did (or maybe a repost of the same social media post, who knows or cares). I don't really want to make an explanation, but anyone who does, here's a link to a bunch of square packing findings... of course, no hydraulic press allowed for these packings. https://erich-friedman.github.io/packing/squinsqu/ [[User:Tsumikiminiwa|Tsumikiminiwa]] ([[User talk:Tsumikiminiwa|talk]]) 22:07, 20 February 2023 (UTC)

:Yeah, this was on r/mathmemes the other day. [[Special:Contributions/172.64.238.48|172.64.238.48]] 00:03, 21 February 2023 (UTC)

Welcome to the Hydraulic Press Channel. Today we have a set of squares that are usually used in packing problems. You are supposed to fit them into other squares by arranging them. But I think we can get them to fit easier if we put them on the press, and just try to make them smaller. We are going to start with one square, and see how much smaller we can make this. And here we go.

:Needs to include a mention of the "Square Packer Five Meeellion"... [[Special:Contributions/172.68.51.141|172.68.51.141]] 16:48, 21 February 2023 (UTC)

The post where I saw this said: “God is dead, and what killed him was learning [the similarly inelegant-appearing n=17 solution].” [[Special:Contributions/172.70.254.216|172.70.254.216]] 13:08, 21 February 2023 (UTC)

Welcome to the Hydraulic Press channel

What does "s<" mean?  [[User:Kev|Kev]] ([[User talk:Kev|talk]]) 22:54, 21 February 2023 (UTC)
:"S" (the size of the square, within which lie the N small squares) is less than the following number. i.e. that any S of that amount or greater is more than enough space to contain N unit squares. But it isn't fully established what the ''smallest'' value of S is, just that it will not be bigger than (or equal to) that provisional limit.
:(Do we need a wikilink to inequality notation in the explanation, then? Maybe you can tell us, Kev.) [[Special:Contributions/172.71.242.191|172.71.242.191]] 23:17, 21 February 2023 (UTC)
::Please! I came to the discussion to ask that an explanation of what s means. I did have a look in the Wikipedia article about it, but they don't use it there. So an explanation in the text with perhaps a link to something that expands on the explanation would be greatly appreciated by me :-) [[Special:Contributions/172.70.91.198|172.70.91.198]] 12:45, 22 February 2023 (UTC)
:::Added something about this. Seems too wordy and partly a repeat of the above. Future editors will refine, no doubt. [[Special:Contributions/141.101.98.77|141.101.98.77]] 19:43, 22 February 2023 (UTC)
:::Well, I ''had'' added it. Someone [https://www.explainxkcd.com/wiki/index.php?title=2740:_Square_Packing&curid=26065&diff=306648&oldid=306624 rewrote it] and it now just says something not at all what the above people wanted it to say... Go figure... [[Special:Contributions/172.70.90.35|172.70.90.35]] 01:10, 23 February 2023 (UTC) 
::::Is there a solution to the problem of the smallest explanation into which n explanations can be packed? [[Special:Contributions/172.70.90.35|172.70.90.35]] 11:29, 23 February 2023 (UTC)

I think I saw this new solution in a paper authored by USPS et al. [[Special:Contributions/108.162.216.159|108.162.216.159]] 23:33, 21 February 2023 (UTC)

I believe we can get S<3.32 for this problem... if it will Blend. --[[Special:Contributions/172.69.79.133|172.69.79.133]] 09:28, 22 February 2023 (UTC)

Assuming that when Randall says "some upgrades", he means the strongest hydraulic press humanity has created, what would be the compressive strength of the square in the title text? ~ [[user:megan|Megan]] <sup>she</sup>/<sub>her</sub> <sup>[[user talk:megan|talk]]</sup>/<sub>[[special:contribs/megan|contribs]]</sub> 01:57, 23 February 2023 (UTC)

First time I've seen a citation in an Explain XKCD explanation, LOL! And if I haven't read all 2740 up until here, I'm close (MAYBE the first few hundred I skipped the explanation if I understood the comic). :) [[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 05:07, 26 February 2023 (UTC)

I'm on mobile so can't easily edit it myself but I think the reference to 11 square packing in 2765: escape speed should be linked to here :)  [[Special:Contributions/162.158.34.23|162.158.34.23]] 11:37, 29 September 2023 (UTC)
