451: Impostor

172.70.47.53: /* Explanation */ So wrong. VSO is not the most rare order, Klingon is OVS, and neither is found in Finno-Ugric.

==Explanation==
While the comic is ostensibly about grad students, it is really [[Randall]]'s way of poking fun at the relative rigor of different fields, reminiscent of [[435: Purity]]. In the comic, [[Cueball]] attempts to pose as an expert in a given field (a [[:Category:Banned from conferences|recurring pastime]] of his) and sees how long it takes before the real experts detect his nonsense.

The first panel shows [[Cueball]] discussing an {{w|engineering}} problem with [[Ponytail]]. Ponytail is talking about an immediate practical problem involving heat dissipation. Cueball suggests 'using {{w|logarithm|logarithms}}' to solve it. Logarithms are a mathematical tool used for expressing an exponential relationship as a linear one. While they may be used to model the effects of heat dissipation over time, Ponytail is looking for a way to change the rate of heat dissipation, like "water cooling." It only takes 48 seconds before he exposes himself.

The second panel shows a conversation with {{w|linguistics|linguistic}} grad students who are apparently discussing the {{w|Finno-Ugric languages|Finno-Ugric language family}} (a family of related languages that includes Hungarian, Finnish, and Estonian). Cueball asks if {{w|Klingon language|Klingon}} is included in this family. The linguists instantly recognize the meaninglessness of the statement — either because Klingon is a constructed language, designed to sound "alien" to avoid sounding like any human language (thus it cannot be part of any real linguistic family), or because "Klingon" is a recognizable pop-culture reference. Either way he has exposed himself after only 63 seconds of conversation.

In the third panel, the humor comes from the fact that the idea of {{w|sociology}} existing to rank human beings on some arbitrary intrinsic value is not only ridiculous in a scientific context, but also politically offensive. Cueball unknowingly recreates the logic behind some of the worst crimes in human history, a problem sociologists are trained to be very aware of. However, it may be something that a less educated non-sociologist would assume could pass within the field. When he describes his unscientific and offensive approach, we see one of the sociology grad students facepalming in exasperation. Because a non-expert may be able to sound somewhat educated in sociology before making such a slip-up, it is four minutes into the conversation before he is detected.

In the final panel, he attempts to pass as an expert in {{w|literary criticism}}. This field notoriously uses a great deal of impenetrable jargon, so when Cueball makes up seemingly meaningless sentences, no one notices. His quip at "deconstructing the self" may be a meta joke about the field itself failing under deconstruction... (or this sentence may be a meta-meta- example of someone applying literary criticism standards to the analysis of this specific comic). We find that rather than being caught out within minutes as in the other fields, he has now published 8 papers and 2 books. The humor comes from the fact that he has accidentally made himself into a recognized authority in the field, despite not having any idea what he was talking about. In this panel, Cueball is sitting in an armchair in the position of an expert lecturing to a student, who sits at his feet apparently absorbing his inane statement.

This implies that the field itself has published a great deal of meaningless things that only superficially look meaningful through the impenetrability of the jargon. The title text challenges the audience to take a look at {{w|Deconstruction|the Wikipedia article for literary deconstruction}} if they don't believe this criticism applies - the Wikipedia article in question is almost constantly flagged for "clean-up" on the grounds that it's a jumbled mess. An archive of the article as it was when this comic was published is available [https://en.wikipedia.org/w/index.php?title=Deconstruction&oldid=225953741 here].

Talk:3065: Square Units

172.70.47.53:

I like this one :) reminds me of trying to use recipes in imperial units with metric equipment [[Special:Contributions/162.158.108.29|162.158.108.29]] 19:48, 19 March 2025 (UTC)

I so want to stand outside Randall's office holding up {{tl|citation needed}} for not giving an actual citation on the title text. [[Special:Contributions/162.158.175.159|162.158.175.159]] 20:07, 19 March 2025 (UTC)

We should start using ares as a common unit of measure. https://www.britannica.com/science/are [[Special:Contributions/172.69.135.15|172.69.135.15]] 20:09, 19 March 2025 (UTC)

The area of eaten vegetation is all well and good, but we really need to know the total volume consumed. In barn-megaparsecs, ideally. [[Special:Contributions/172.71.241.89|172.71.241.89]] 21:26, 19 March 2025 (UTC)

I just got the mail notification for this and the previous comic at the same time. I would say that Randall forgot to send out the previous one before, but surely this is automated, so I guess something went wrong with that setup.

I really want to know what the 80-fold error was now [[User:Thief|Thief]] ([[User talk:Thief|talk]]) 10:54, 20 March 2025 (UTC)
: Here's an error in chemical names instead--Diphenhydramine (Benadryl) occasionally appears as diphenhydrazine, which (if it existed) might be a rocket fuel. Google for it, just for scientific fun. Rocket flight to Australia, now in your local pharmacy! [[Special:Contributions/172.69.71.207|172.69.71.207]] 11:38, 20 March 2025 (UTC)
::There's a dangerous point of confusion between diphenhydramine and dimenhydrinate (Gravol). In medical contexts, the two are often given differing capitalizations to emphasize the differences between the words, to reduce the risk of patients being given the wrong one (e.g. dimenhyDRINATE vs. diphenhydrAMINE). [[User:BunsenH|BunsenH]] ([[User talk:BunsenH|talk]]) 14:51, 20 March 2025 (UTC)
::Realistically, if "diphenhydrazine" is diphenylhydrazine, it would be a much poorer rocket fuel than hydrazine. It's a known substance, used in chemical manufacture, melting point a bit above the boiling point of water, moderately nasty in terms of health risks. Flammable, yes, but not particularly exciting.

The land area of Australia really depends on when it last rained. There are very large areas that will be completely dry prior to rain that will be flooded after. [[User:SDSpivey|SDSpivey]] ([[User talk:SDSpivey|talk]]) 12:28, 20 March 2025 (UTC)

You should never write `square cm`, etc. but always `cm²`. Same for seemingly standard abbreviations: Don't write `ccm` for "cubic centimeter", but `cm³`. Even though, in spoken language "square centimeter" is correct. Another confusion can sometimes arise from not knowing that squaring or cubing binds less than the centi-/kilo-/... prefix. I.e., `cm³` is `(0.01m)³` not `0.01(m³)`. A liter (`l`) is `0.001m³` or `1dm³ = (0.1m)³`. A milliliter is `0.001l = 0.000001m³ = (0.01m)³ = 1cm³` --[[Special:Contributions/172.69.109.92|172.69.109.92]] 12:48, 20 March 2025 (UTC)
:All you need to remember is:
:"X units square" = a square of X units = (X units)² '' = X² (units²) ''
:"X square units" = X times a square unit = X (units²) '' = (√X units)² ''
: "X prefixunits" is (X × prefix) units, for the sake of preserving the units ''so "7 decagrammes" is "70 grammes" (or 0.07 kg, if you need that, for whatever reason) [though not to be confused with "grammage", which is "grammes per square metre"!] and "450 nanometres" is "450×10<sup>-9</sup> metres" or "4.5×10<sup>-7</sup> metres"'' [[Special:Contributions/172.69.195.62|172.69.195.62]] 14:26, 20 March 2025 (UTC)

I don't see that the table is too wide to display (on a "normal" full-hd screen). But I agree that more than ~3 significant digits are kind of useless. We could even add a column with the unit "area of Australia" --[[Special:Contributions/172.71.160.61|172.71.160.61]] 16:19, 20 March 2025 (UTC)

Another point: The percentage "gain" column is mostly wrong, e.g. from 1 to 144 you have a "gain" of 143 or 14300% not 14400% (I'd rather show a gain factor though). --[[Special:Contributions/172.71.160.60|172.71.160.60]] 16:18, 20 March 2025 (UTC)

There are other mistakes being made in communicating the factoid. One is called out by the comic itself (namely the defoliation of Australia in particular rather than a nondescript Australia-sized area of land), but there are others too. For example, it has become more ambiguous whether the factoid is about a single insect or the insect as a species. It'd be somewhat believable if you're talking about an entire species eating that much per day. The other miscommunication is that it's gone from talking about grass to foliage in general, but foliage in general can vary in density a lot more than a patch of grass, creating additional inaccuracies.
