Hello! First time i got to a comic first --[[Special:Contributions/172.69.176.76|172.69.176.76]] 06:17, 8 May 2025 (UTC){{unsigned ip|104.23.175.202}}
:Well [[269: TCM|first of all]] remember to sign your comments :-). But congratz... --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 05:42, 8 May 2025 (UTC)
::Sorry.
::I now realize that that was an extremely trollish thing to do. ٠ـ٠

I believe he indicates that a globe is made by making a copy of the Earth, and then compressing it until it fits on a desktop. Hence having the same mass and thus the same Schwarzschild radius as Earth. I have changed the explanation a bit because of this observation.--[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 05:42, 8 May 2025 (UTC)

Gotta wonder what kind of a desk could support a desktop globe that weighs as much as the Earth
--[[User:StumbleRunner|StumbleRunner]]
:[...] desk? Convince me that such a globe wouldn't plunge straight through the Earth's crust and into the mantle. I sense a marketing problem. [[Special:Contributions/172.71.147.69|172.71.147.69]] 07:07, 8 May 2025 (UTC)

Radius. <s>Is there a typo in the comic where 7/10" should be 7/20", i.e., 0.35" as later written? Or would a 7/10" Earth collapse into a black hole nonetheless?</s>[[Special:Contributions/172.71.154.129|172.71.154.129]] 06:40, 8 May 2025 (UTC)
:Nope… the Schwarzchild radius is 0.35", which is indeed 7/20", but the measurement shown on the globe is the diameter, not the radius, so 7/10" is correct. [[Special:Contributions/172.71.178.143|172.71.178.143]] 06:49, 8 May 2025 (UTC)

172.71.147.69: comment about recursive calendars

Would this basically be triangle numbers? So on Christmas Eve you would open 300 windows?[[User:Tommyds|Tommyds]] ([[User talk:Tommyds|talk]]) 16:01, 2 December 2024 (UTC)

Yes and no. It's not 12 days of Christmas (as mentioned in the title text), so only the overall number of gifts are a triangle number; you open 30 windows on Christmas Day. The 12 days ref is key as the song generates more gifts if taken literally even in 12 days -- 78 on the last day, 66 on the previous day, etc, for a total of 364.

Notice that this year The Advent calendars are correct.
Normally, Advent calendars start at the 1st of December even if the Advent starts at a different day.
But this year the Advent also starts at the 1st of December. [[Special:Contributions/162.158.172.40|162.158.172.40]] 16:55, 2 December 2024 (UTC)

Donald Knuth wrote a paper for April 1984 Communications of the ACM that included an analysis of the complexity of 12 Days of Christmas. It's in the CACM archive https://dl.acm.org/doi/pdf/10.1145/358027.358042.

The explanation currently says "each day, he gets another advent calendar, which each contains 24-25 different items". I don't think that's correct; look at the picture: each day's calendar has one fewer item than the previous one. For example, the 24th only has 2 boxes and the 25th only has one. --[[User:Itub|Itub]] ([[User talk:Itub|talk]]) 17:25, 2 December 2024 (UTC)

Perhaps each smaller advent calendar might also contain a smaller advent calendar and so on ...? [[Special:Contributions/172.70.90.199|172.70.90.199]] 17:51, 2 December 2024 (UTC)
:Since the 1st has a calendar with a 1st, that would mean an infinite number of calendars just on the first day, so probably not. [[Special:Contributions/172.71.154.225|172.71.154.225]] 18:03, 2 December 2024 (UTC)
::It could work out if you don't open the first window of a new advent calendar on the day that it is revealed. So on day 1, you open the first window revealing an advent calendar that starts on day 2. Then on day 2 you open the second window, revealing a second advent calendar and the first window of the day 1 advent calendar, revealing a third advent calendar. ... and so on. If my mental math on that is right, it's doubling every day, so 2^24 =~ 16M calendars in total? (I could be off by a day) [[Special:Contributions/172.71.147.69|172.71.147.69]] 19:38, 2 December 2024 (UTC)
