I prefer qwerty: I'ts a robot!

Boston Dynamics does this. [[User:Netherin5|“That Guy from the Netherlands”]] ([[User talk:Netherin5|talk]]) 16:23, 25 March 2019 (UTC)

I have to wonder if the title text is referring to the term "search and destroy", which would certainly be the second type. [[User:MAP|MAP]] ([[User talk:MAP|talk]]) 18:47, 25 March 2019 (UTC)

Talk:2123: Meta Collecting

2019-03-17T20:49:57Z

I prefer qwerty: Second item on top shelf.

RIP {{w|List of collectables}} and grammar. It’s collectable. Not collectible, collectable. [[User:Netherin5|Netherin5]] ([[User talk:Netherin5|talk]]) 16:07, 13 March 2019 (UTC)
:You may disagree, but collectable is also correct. https://en.oxforddictionaries.com/definition/collectable [[Special:Contributions/108.162.242.23|108.162.242.23]] 16:21, 13 March 2019 (UTC)
:I think we’re agreeing here? I also use collectable, and said so in my comment. At least it should be used in this case, because it’s what Wikipedia uses on said page. [[User:Netherin5|Netherin5]] ([[User talk:Netherin5|talk]]) 16:26, 13 March 2019 (UTC)
:My understanding was that the words had different meanings. Something is collectible if it would have a place in a collection; a Harley is collectible because it would have a place in Cueball's collection of items. Something is collectable if it can be collected; a court judgement may be collectable if the person ordered to pay has enough money to make the payment. [[User:D5xtgr|D5xtgr]] ([[User talk:D5xtgr|talk]]) 17:33, 13 March 2019 (UTC)
::Suspiciously enough, that’s the exact example I got when I googled it, but thank you for the collection. I only say this because of the article in question discussed. [[User:Netherin5|Netherin5]] ([[User talk:Netherin5|talk]]) 17:41, 13 March 2019 (UTC)
:::Yes, I was having a hard time wording my original example - it's rather easier to show why a debt or court judgement ''wouldn't'' be collectable than to explain why one ''would'' be. [[User:D5xtgr|D5xtgr]] ([[User talk:D5xtgr|talk]]) 18:54, 13 March 2019 (UTC)
: Googling "collectible define" or "collectable define", we get that both seem to be correct. https://writingexplained.org/collectible-vs-collectable-difference says collectable is typically the British spelling of the word.

First time posting here, so my format might be terrible. But looking at the list of collectables; Maytag is listed, and the reference is for antique scales, so definitely not dryers. [[Special:Contributions/173.245.54.7|173.245.54.7]] 16:13, 13 March 2019 (UTC)
:Antique washer models to scale? Fixed it. On a serious note, it’s just one source, there are probably people who would collect washers, or, the more likely option, they just saw Maytag and thought “washers” EDIT: As a formatting nerd, it’s good.

Wikipedia intern: "Mr. Sanger? Randall made a comic about us again." Larry Sanger: "Godammit, what page do we have to lock this time?" [[User:GreatWyrmGold|GreatWyrmGold]] ([[User talk:GreatWyrmGold|talk]]) 04:21, 14 March 2019 (UTC)

I already suggested this [https://www.explainxkcd.com/wiki/index.php/2099:_Missal_of_Silos before] that I think we can have a new collected page of xkcd Wikipedia edit wars. I doubt the trivia in 2099 is the full list, or is it? Are there not that many cases as I think to be worth it? [[Special:Contributions/162.158.118.22|162.158.118.22]] 04:48, 14 March 2019 (UTC)
: Well, [https://en.wikipedia.org/wiki/Xkcd#Wikipedia_vandalism Wikipedia] has the list now, so I'm satisfied. [[Special:Contributions/162.158.118.46|162.158.118.46]] 05:59, 15 March 2019 (UTC)

As of right now, Randall has got his wish: the page is protected. Unfortunately, it's protected with "yachts" on it and, of course, it can't be reverted because of the protection. [[User:Jeremyp|Jeremyp]] ([[User talk:Jeremyp|talk]]) 10:45, 14 March 2019 (UTC)
:On the plus side, old yachts that are no longer seaworthy but still collectable are quite common on craigslist for under $10,000. Even cheaper yet, just ask any marina owner for abandoned sunken yachts you can have just for getting them out of the waterway.[[User:Seebert|Seebert]] ([[User talk:Seebert|talk]]) 13:06, 14 March 2019 (UTC)
:It's gone now. The edit history is quite entertaining though. "Added boating category" [[User:Linker|Linker]] ([[User talk:Linker|talk]]) 17:15, 14 March 2019 (UTC)
::Looks like one of the editors got a bit overzealous and deleted Element Collecting because they thought it was an xkcd reference. [[User:CJB42|CJB42]] ([[User talk:CJB42|talk]]) 05:38, 15 March 2019 (UTC)
:::That sucks. That is such a real hobby though. There is this guy who made a wooden periodic actual table and put elements on it in each of their places. He takes beautiful photos of them.

Interesting choice of username, xkcd2123. {{unsigned|103.22.200.210}}

It is disappointing that xkcd readers think it's funny to vandalize the wikipedia article because of this comic. I highly doubt that Randall himself did so, and I don't think he intended for anyone else to actually vandalize it either. Furthermore, giving these viewers any satisfaction by actually including this info in the comic discussion seems somehow inappropriate. [[User:Ianrbibtitlht|Ianrbibtitlht]] ([[User talk:Ianrbibtitlht|talk]]) 13:11, 15 March 2019 (UTC)

I think that the second item on the top shelf may be a bottle of perfume.[[User:I prefer qwerty|I prefer qwerty]] ([[User talk:I prefer qwerty|talk]]) 20:49, 17 March 2019 (UTC)

If the left side controls the top half of the body, wouldn't that mean it also controls the right half? [[Special:Contributions/108.162.241.248|108.162.241.248]] 20:04, 6 March 2019 (UTC)

: I'm referring exclusively to the hypothetical model posed by the comic; rather than the reality.

I don't think the sentence "all 3 claims are false" is accurate. I think the claim that the right side of your brain controls the left side of your body is accurate. It says so on the Wikipedia article mentioned and in several other sources. What the Wikipedia article disputes is whether or not "higher-level" functions are partitioned to one side of the brain.

: With regard to the retina, the right half of the brain processes what the right half of each retina receives, and the left half processes what the left half of each retina receives (see e.g. [https://nba.uth.tmc.edu/neuroscience/m/s2/chapter15.html optic nerve]), but because our retina is behind the focal point of our lens so all the lightbeams cross and images hit the back of the eyeball upside-down and backwards, that means the halves of our brain process the opposite halves of what we see. But it's the same side of our body! I stopped learning neuroscience after we got to the optic nerve ;p [[Special:Contributions/108.162.221.95|108.162.221.95]] 21:48, 6 March 2019 (UTC)
: You must've stopped in the middle of the lesson, because the optic nerves split so that both brain halves get a copy of each eye. Your own link points it out in the figure as the "Optic chiasm".--[[User:Henke37|Henke37]] ([[User talk:Henke37|talk]]) 13:09, 7 March 2019 (UTC)
:: If you look closer, you can see how the left half of each eye (retina) goes only to the left half of the brain, and same for the right, even though both eyes do go to both sides. The split is by what is seen, not which eye sees it, which specially maps to the left side or right side of the eyeball. [[Special:Contributions/162.158.79.185|162.158.79.185]] 19:03, 7 March 2019 (UTC)

:I think the "right side of your brain controls the left side of your body" is NOT accurate, it's just closer to truth than the reverse. Some parts of perception and motor control are divided that way, but unless you have corpus callosotomy the high-level control is centralized and/or distributed regardless the side. Would be hard to synchronize both hands if not. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 02:05, 7 March 2019 (UTC)

Having survived an ischemic stroke on the left side of my brain, which temporarily paralyzed the right side of my body, this comic speaks to me like none other.

Is it possible that the title text is a reference to the whole "magnetic north is actually south" thing? {{unsigned ip|162.158.78.208}}

Completely rewrote the explanation. There are two key phrases that were removed with the following justifications:

'''"left arm and left leg, and vice versa for the left half of the brain, and competing theories such as [https://arxiv.org/pdf/1003.1872.pdf these] [https://link.springer.com/article/10.1007%2FBF02972358 two] attempt to explain why this is the case."
'''
Those are not competing theories. It is the abandonment of one old theory in favor of a one that is better supported with evidence! It's like saying "There are competing theories of what an atom is actually made out of. One says that they are the smallest indivisible part of all matter. Another says that they are like plum-puddings with with a positive charge particle studded with negative charge corpsucles. And the last theory of what an atom is is a core particle with positive charge, made of many many smaller parts, surrounded by an probability/statistical cloud of negative particles which can act as both particles and waves and cannot have their speed and location determined at the same time.

... And if you think these are all "competing" and equally valid theories of what an atom is... I can not help you. Please... I don't know. Take a class or read a textbook or something. Good luck. May God have mercy on you.

'''Similarly, many people incorrectly argue that different parts of the brain control logic and emotion, due to the importance of the [https://www.sciencedirect.com/science/article/pii/S0028393211000285?via%3Dihub left] brain for language processing.
'''
Removed and replaced it with a better explanation. Not technically "incorrectly argue". There is basis for which the arguments are founded.

The concern about the left leg being independent of the brain can be confirmed. Just scratch your left side, and watch your left leg kick.

I don't have time to properly research now, but could some conjoined twins be a real world example of disputed/dual control on some parts of their bodies?
