Editing Talk:1260: LD50

There's one toxicology paper that's facing us instead of laying flat. Is it just me, or is there a funny "concerned" face on it? --[[User:Druid816|Druid816]] ([[User talk:Druid816|talk]]) 05:58, 4 September 2013 (UTC)

Oh my, when I checked the comic this morning I didn't even see Cueball lying underneath the stack of toxicology papers... --[[User:Buggz|Buggz]] ([[User talk:Buggz|talk]]) 06:17, 4 September 2013 (UTC)

Is there any way to move this page from LD50 to LD<sub>50</sub>? [[Special:Contributions/208.120.153.144|208.120.153.144]] 06:31, 4 September 2013 (UTC)
:We try to stay as faithful to the main xkcd comics as possible when referencing xkcd materials. If the comic title on xkcd.com is LD50, it's LD50 here too.

Wait, that's just one scientist out of three that died of toxicity data. Doesn't that mean, that they've only determined LD<sub>33</sub>? Is there any way to estimate LD<sub>50</sub> from LD<sub>33</sub>? Imho the exact distribution of death rate / dose would have to be known up to one free parameter for such an estimate... -- [[User:Xorg|Xorg]] ([[User talk:Xorg|talk]]) 10:56, 4 September 2013 (UTC)

:I tried to address this with an edit.  Betwixt the ultimate and penultimate ("...he/she weighs.") sentences I started to add:
::Presumably, for every recorded death a statistically matched second person survived the same load.  In this case ''perhaps'' this is the Cueball scientist behind the Megan scientist, although he is now obviously unencumbered.

:::But what do we know, maybe Cueball is only half dead.{{unsigned ip|189.186.105.168}}

:...although it started to run away with me.  Was also going to say something about saving paper by re-using the 'test dose', or something, but it's already getting too long.  But someone might be able to edit it (and even re-arrange it) better than I. [[Special:Contributions/178.106.190.241|178.106.190.241]] 11:42, 4 September 2013 (UTC)
:Second-thoughts edit!  The person beneath the documentation isn't ''necessarily'' the dead one (in any given pair)!  He lacks any obvious signs of being deceased (e.g. "a cross for an eye", by common cartoon standards, albeit that cueballs generally don't have eyes, or signs of bodily breakage or presumably vital fluids slowly seeping across the floor, or...).  Thus maybe this is one of the (uncomfortable!) survivors from the cohort of testees, being observed.  If only Randall would have added a sign of death (or life, like a "groan") then we could get on with our lives!  (Unlike fully half of those tested upon.)

A third edit from me: Regular printing paper's density (according to Wiki) is 800kg/m³, with the human body being slightly less than 1000kg/m³ as a ready reckoner (oh, go on then... wiki says... oh, it doesn't, obviously at least...  well, given how we float in water, I'd estimate it at 850-950kg/m³).  Doesn't that pile of literature (even assuming air gaps, and possibly some lamination/plastic covering of perhaps even less dense nature) look a ''little'' more than than twice-and-a-bit the volume of the typical Cueball beneath, even unflattened and unstickified?  Right, that was my last edit.  Honest. [[Special:Contributions/178.106.190.241|178.106.190.241]] 12:02, 4 September 2013 (UTC)

Could it be that by "administered orally", Randall means "verbally" (i.e. read out loud)?  I think that could be quite a funny interpretation... :-) [[User:Gregatar|Gregatar]] ([[User talk:Gregatar|talk]]) 18:56, 4 September 2013 (UTC)

I totally agree with this 'verbally' thing, I was thinking the same, that a too large set of data read out loud would be fatal after a few 100 pages :) Include in explanation?

Something is very wrong here. The LD50 is the dose required to kill HALF of the test population, but here we see only one guy, and he's presumably either dead or not-dead. The "2kg/kg" figure suggests that if you drop 2x each person's weight in paper on an entire population, *half* of them will die. {{unsigned ip|58.28.131.238}}

:I don't think it's wrong, Randall just didn't draw all the experiments (like in [http://xkcd.com/882/ Significant]), but just the last one. The humour is just to show how the experiment is performed, not how many people it kills. The LD50 term just adds fun by using toxicology jargon.--[[Special:Contributions/92.231.34.227|92.231.34.227]] 14:25, 5 September 2013 (UTC)

When I first read this, I thought it was referring to a [https://en.wikipedia.org/wiki/Fork_bomb| fork bomb], saying that the data was toxic to the computer and that the data's mass is twice its own mass, i.e. its size doubles before you know it.  The toxicology explanation does seem more convincing though.

The explanation of subcutaneous injection mentions blood clots in vessels. Subcutaneous injection in used in the medical field to refer to injections under the skin, but not inside muscle (intramuscular) or inside the veins (intravenous). IV would clearly be more lethal at a lower dose than subcutaneous and I would imagine Randall's intent was to describe an IV injection. I would expect the cause of death from paper particles injected under the skin to be infection if a small to moderate amount of paper was used to hemorrhage due to mechanical tearing of the skin and underlying tissues in a high dose.[[Special:Contributions/99.126.226.212|99.126.226.212]] 05:25, 7 September 2013 (UTC)
