Another ghost cueball comic! You can see it in the last panel. [[Special:Contributions/108.162.216.54|108.162.216.54]] 06:03, 22 April 2021 (UTC)

==> Is that something that has happened before? First time noticing it. Is it just a remnant of the sketching? Of doest it mean something? [[Special:Contributions/162.158.93.213|162.158.93.213]] 13:21, 22 April 2021 (UTC)

Someone needs to add an explanation of the Lambda, and possibly how Excel is implementing it. (I suppose it would immediately be useful for cutting down common re-use within a formula line, though =IF(ISERR(FIND(":",A1)),A1,RIGHT(A1,LEN(A1)-FIND(":",A1))) is a trivial repeat of the FIND, once to check, then again to do, I often need to do far more nested things, check for being a value, repeat the FIND to deal with the LEFT, etc.) But it has the smell of being effectively a Macro in this instance. Which already seems to me to be the only way to run a ''proper'' Turing Machine in an Excel column without hitting Circular Reference issues.

Would it be a stretch to say that Turing's inability to prove if Cueball will stop is actually equivalent to the halting problem, except it is for Cueball and not an arbitrary Turing machine? I thought that was pretty funny. [[User:XTheBHox|xTheBHox]] ([[User talk:XTheBHox|talk]]) 11:30, 22 April 2021 (UTC)

Microsoft themselves claim that the addition of LAMBDA makes Excel turing-comlpete (see here: https://techcommunity.microsoft.com/t5/excel-blog/announcing-lambda-turn-excel-formulas-into-custom-functions/ba-p/1925546). Based on this comic, I would argue that it already was... [[Special:Contributions/162.158.159.36|162.158.159.36]] 12:55, 22 April 2021 (UTC)

==> Someone has already made Conway's game of life in excel (http://dailydoseofexcel.com/archives/2011/04/06/conways-game-of-life-simulation-in-excel) and game of life has been shown to be Turing complete. [[User:Kvarts314|Kvarts314]] ([[User talk:Kvarts314|talk]]) 13:28, 22 April 2021 (UTC)

==> Since Excel has a way to store and do math on numbers, and also a way to 'point' to a certain cell, it is Turing-complete. A lambda function is not necessary for Turing-completeness (e.x. a turing machine does not have one.) [[Special:Contributions/162.158.255.250|162.158.255.250]] 15:14, 22 April 2021 (UTC)

Typical, I think nobody's actually going to try to explain this, and I get Save Conflicted. My (wordier) version. In case any of it is useful.
:The sky is ever changing, and can often give interesting views such as that illustrated in the comic. Cueball and Megan seem to be agreeing about this, and its pleasing nature.
:As (ignoring particularly unusual viewpoints, severe topography and obscuring vegetation/architecture) the sky is pretty much the upper hemisphere of any external view, it is inded a "half". It would seem to be redundant to say it is "one of my favourite halves", as that indicates both a list of at least two items to choose from ''and'' more than one 'favourite'. Being in 'the top two of a list of two' actually means nothing. But the other half could be the ground ''or'' the sea, ''or'' a composite of the two, so conceivably there ''might'' be more than two 'halves' to choose from in this case. Not that the statement makes much more sense.
:The title-text acknowledges the fact that the other half can have snakes (the land), shipwrecks (the sea) and rocks (either), in a manner that sounds like justifications for any non-sky 'halves' being interesting too, to the kind of people Cueball and Megan seem to be. But it also suggests that by removing all of these you'd be seeing sky, below, that people on the other side of the 'rocks' (the whole Earth) had been seeing as their own 'sky above'. At least until the effects of entirely removing the substance of the planet start to show, of course.

My read on the "halves" bit is the Biblical Genesis bit where the world was split into sky and sea, "And God said, “Let there be a vault between the waters to separate water from water.” So God made the vault and separated the water under the vault from the water above it. And it was so. God called the vault “sky.” And there was evening, and there was morning—the second day." -[[Special:Contributions/173.245.56.112|173.245.56.112]] 14:36, 27 July 2015 (UTC)

I think it's important that Megan says the sky is ONE of her favorite halves, and that the explanation "at least at their present location...the ground is dark, flat, and otherwise boring" is thus too simplistic. The ground where they are standing is in silhouette (it's presumably sunrise or sunset), but I think the implication is that C. and M. (who are obviously not finding words adequate to express how they feel about what they're seeing), are awed by the beauty of Nature, regardless of whether it's sky, sea (shipwrecks), land (rocks) or living things (snakes).[[User:Jv|Jv]] ([[User talk:Jv|talk]]) 15:01, 27 July 2015 (UTC)

Is it possible that the meaning of Megan's statement is that there are other binary sets where she prefers one over the other? For example, her favorites might include (in addition to sky) female, light, and loud. [[User:Smperron|Smperron]] ([[User talk:Smperron|talk]]) 16:43, 27 July 2015 (UTC)

What i understand under "favorite halves" is not about the mentioned tautology but about other things you can differentiate two halves and you like one more than the other.
My personal favorite halves in this sense would be; Sky(vs Earth), women(vs men), low alcohol drinks(vs liquors), etc 17:11, 27 July 2015 (UTC)[[Special:Contributions/141.101.103.202|141.101.103.202]] Bkack

There are multiple ways to split the earth into halves, so I don't think having one favorite way makes any tautology. For example, you can split North/South, East/West, sky/earth, water/earth, day/night. [[User:DMiller|DMiller]] [[Special:Contributions/173.245.50.150|173.245.50.150]] 18:28, 27 July 2015 (UTC)

I don't think it is a "tautology": a trivially true fact, eg "all red shoes are red". If anything it is an oxymoron (as it implies both halves are favourite, and so neither is). [[User:Zeimusu|Zeimusu]] ([[User talk:Zeimusu|talk]]) 18:58, 27 July 2015 (UTC)

"Mathematically, stating one of my favorites it must imply that there must be at least one other favorite" - Not mathematically, but intuitively (unless you can prove the implication). Mathematically, this just says that "Sky" is a member of the set "Favorite Halves", which may or may not include more elements. Intuitively, we don't talk like that unless there is another favorite.-[[Special:Contributions/173.245.50.91|173.245.50.91]] 21:38, 27 July 2015 (UTC)

I'm not so sure that the sky being one of Megan's favourite halves is either tautological or an oxymoron. It could simply mean that, of any given pair that can be described as two halves, she always has a preference for one over the other. Thus, of "earth / sky", "sky" is her favourite half, whereas perhaps of "Bonnie / Clyde", "Bonnie" might be her favourite half. In this way one could have many favourite halves. --[[Special:Contributions/141.101.98.162|141.101.98.162]] 08:02, 28 July 2015 (UTC)
: this ties in well with the recently popular theme of sets with the same number of elements being similar. (So even as Characters can't tell the dwarves from the days of the week, they also separate all pairs into 'favorite' and 'meh' piles.) This made more sense in my head, huh? [[Special:Contributions/141.101.88.224|141.101.88.224]] 14:06, 28 July 2015 (UTC)

I don't think "one of my favourite halves" ''needs to'' be a tautology. It only is if we consider it one of the favourite halves of the same whole, but the set of favourite halves could easily be something like [the sky, yolk, front meant, dark side of the Moon,...], that is, favourite halves of various things. Of course, it would be rather quirky to keep track of favourite halves like that, but I think it is not beyond xkcd.

I'm not so sure that the sky being one of Megan's favourite halves is either tautological or an oxymoron. It could simply mean that, of any given pair that can be described as two halves, she always has a preference for one over the other. Thus, of "earth / sky", "sky" is her favourite half, whereas perhaps of "Bonnie / Clyde", "Bonnie" might be her favourite half. In this way one could have many favourite halves. --[[Special:Contributions/141.101.98.162|141.101.98.162]] 08:02, 28 July 2015 (UTC)
: this ties in well with the recently popular theme of sets with the same number of elements being similar. (So even as Characters can't tell the dwarves from the days of the week, they also separate all pairs into 'favorite' and 'meh' piles.) This made more sense in my head, huh?

I don't think "one of my favourite halves" ''needs to'' be a tautology. It only is if we consider it one of the favourite halves of the same whole, but the set of favourite halves could easily be something like [the sky, yolk, front meant, dark side of the Moon,...], that is, favourite halves of various things. Of course, it would be rather quirky to keep track of favourite halves like that, but I think it is not beyond xkcd.

162.158.255.250:

Typical, I think nobody's actually going to try to explain this, and I get Save Conflicted. My (wordier) version. In case any of it is useful.
:The sky is ever changing, and can often give interesting views such as that illustrated in the comic. Cueball and Megan seem to be agreeing about this, and its pleasing nature.
:As (ignoring particularly unusual viewpoints, severe topography and obscuring vegetation/architecture) the sky is pretty much the upper hemisphere of any external view, it is inded a "half". It would seem to be redundant to say it is "one of my favourite halves", as that indicates both a list of at least two items to choose from ''and'' more than one 'favourite'. Being in 'the top two of a list of two' actually means nothing. But the other half could be the ground ''or'' the sea, ''or'' a composite of the two, so conceivably there ''might'' be more than two 'halves' to choose from in this case. Not that the statement makes much more sense.
:The title-text acknowledges the fact that the other half can have snakes (the land), shipwrecks (the sea) and rocks (either), in a manner that sounds like justifications for any non-sky 'halves' being interesting too, to the kind of people Cueball and Megan seem to be. But it also suggests that by removing all of these you'd be seeing sky, below, that people on the other side of the 'rocks' (the whole Earth) had been seeing as their own 'sky above'. At least until the effects of entirely removing the substance of the planet start to show, of course.

I can't defend this position properly (other than by appealing to shipwrecks) but I'm pretty sure "the other half" is the ocean (or water in general) and that this is a callback to something in early XKCD (the halves thing.) I don't care enough to find the reference though, so FFTI. [[Special:Contributions/141.101.88.224|141.101.88.224]] 13:18, 27 July 2015 (UTC)

My read on the "halves" bit is the Biblical Genesis bit where the world was split into sky and sea, "And God said, “Let there be a vault between the waters to separate water from water.” So God made the vault and separated the water under the vault from the water above it. And it was so. God called the vault “sky.” And there was evening, and there was morning—the second day." -[[Special:Contributions/173.245.56.112|173.245.56.112]] 14:36, 27 July 2015 (UTC)

: Agreed, this appears to be a biblical reference - [[https://www.biblegateway.com/passage/?search=Genesis+1&version=GNT| this version]] explains it pretty clearly. [[Special:Contributions/108.162.249.177|108.162.249.177]] 14:41, 27 July 2015 (UTC)

I think it's important that Megan says the sky is ONE of her favorite halves, and that the explanation "at least at their present location...the ground is dark, flat, and otherwise boring" is thus too simplistic. The ground where they are standing is in silhouette (it's presumably sunrise or sunset), but I think the implication is that C. and M. (who are obviously not finding words adequate to express how they feel about what they're seeing), are awed by the beauty of Nature, regardless of whether it's sky, sea (shipwrecks), land (rocks) or living things (snakes).[[User:Jv|Jv]] ([[User talk:Jv|talk]]) 15:01, 27 July 2015 (UTC)
:The general idea here seems most reasonable to me. The sky is great (see also [[1117: My Sky]]), but so is the Earth. I find all this debate over possible implications of "one of the" almost absurd.[[Special:Contributions/162.158.255.250|162.158.255.250]] 02:44, 29 July 2015 (UTC)

Is it possible that the meaning of Megan's statement is that there are other binary sets where she prefers one over the other? For example, her favorites might include (in addition to sky) female, light, and loud. [[User:Smperron|Smperron]] ([[User talk:Smperron|talk]]) 16:43, 27 July 2015 (UTC)

What i understand under "favorite halves" is not about the mentioned tautology but about other things you can differentiate two halves and you like one more than the other.
My personal favorite halves in this sense would be; Sky(vs Earth), women(vs men), low alcohol drinks(vs liquors), etc 17:11, 27 July 2015 (UTC)[[Special:Contributions/141.101.103.202|141.101.103.202]] Bkack

There are multiple ways to split the earth into halves, so I don't think having one favorite way makes any tautology. For example, you can split North/South, East/West, sky/earth, water/earth, day/night. [[User:DMiller|DMiller]] [[Special:Contributions/173.245.50.150|173.245.50.150]] 18:28, 27 July 2015 (UTC)

I don't think it is a "tautology": a trivially true fact, eg "all red shoes are red". If anything it is an oxymoron (as it implies both halves are favourite, and so neither is). [[User:Zeimusu|Zeimusu]] ([[User talk:Zeimusu|talk]]) 18:58, 27 July 2015 (UTC)

Am I the only one who sees a possible (additional) visual joke in the second panel? (The drawing is divided along the diagonal: One half is mainly cloudy, another mostly clear sky.) [[Special:Contributions/162.158.92.44|162.158.92.44]] 19:37, 27 July 2015 (UTC)

In terms of two halves, should we mention https://xkcd.com/731/ "Desert Island?" It seems to be relevant in this situation, but I want someone else's opinion first. Also, mobile sucks for that kind of stuff, so... [[Special:Contributions/108.162.216.110|108.162.216.110]] 20:45, 27 July 2015 (UTC)

"Mathematically, stating one of my favorites it must imply that there must be at least one other favorite" - Not mathematically, but intuitively (unless you can prove the implication). Mathematically, this just says that "Sky" is a member of the set "Favorite Halves", which may or may not include more elements.
