In the comic, french word &amp;quot;étymologie&amp;quot; is incorrectly spelled &amp;quot;ethimologie&amp;quot; which is referred to as &amp;quot;Old French&amp;quot;. I wonder whether that mistake was done on purpose ?&lt;br /&gt;

&lt;br /&gt;
What? No mention of the irony that an organization whose purpose is to preserve the history of words has accidentally done the opposite--supplanting and obscuring the word for the very thing they are trying to do?&lt;br /&gt;
:(Documenting and) preserving the history of words is not the same as preserving words in their current usage. Hence providing a service that becomes so ubiquitous that it's name supplants the previous word used to refer to the science on which that service is based is not in opposition to the service's aim of compiling a systematic collection of etymonlinear explanations. Indeed, it is an example of the changes in language absent which the science of etymonline would simply not exist. But I agree it's a bit ironic.&lt;/div&gt;</summary>

&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by a SUPERMASSIVE BOWLING BALL - Need a full analysis of each graph (preferably with input from someone who understands bowling). Do NOT delete this tag too soon.}}&lt;br /&gt;
&lt;br /&gt;
This series of line graphs purports to advise players on how to improve their odds of achieving a strike in the sport of {{w|bowling}} – presumably {{w|ten-pin bowling}}, the most popular version of the sport in the United States. As is typical for Randall, however, things start off halfway reasonable and quickly escalate to the absurd. Among the parameters being measured, that being angle, throwing speed, spinning speed, and weight of the ball, the latter three are on {{w|logarithmic scale}}s, making them encompass ranges larger than would be useful for reference by a bowler, up to values that are physically impossible for a human to achieve. {{Citation needed}}&lt;br /&gt;
&lt;br /&gt;
The first line graph indicates that a bowler has the greatest chance of achieving a strike by aiming the ball directly at the pins, with the chance of a strike decreasing rapidly as the ball is aimed to the left or the right. Even a novice bowler already knows to aim the ball at the pins, not elsewhere. While a novice bowler may have difficulty achieving a 0° angle roll, their roll would still not come close to a -90° or 90° angle (due left or due right), much less a -180° or 180° angle (which, in either case, would be the opposite direction from the pins). Unlike with the other graphs, it is physically possible for a bowler to aim the ball at any angle, albeit not permissible under bowling rules; aiming the ball at an angle which deviates significantly from 0° would create a risk of the ball going into one of the other lanes or missing the lanes entirely, which would annoy or anger other bowlers and employees of the bowling alley.&lt;br /&gt;
&lt;br /&gt;
The second graph indicates that a bowler has the greatest chance of achieving a strike by throwing the ball about 10 m/s (22 mph or 36 kph), with the chance of a strike decreasing as the speed is increased or decreased. Most bowlers cannot throw more than 100 m/s (224 mph or 360 kph) {{Citation needed}}. According to the graph, any throw faster than 100 m/s would cause equipment damage, and then becomes actually responsible for widespread destruction by the time that increase is several order of magnitudes later. The graph ends at the speed of light, ''perhaps'' as it is physically impossible to throw anything faster {{Citation needed}}.&lt;br /&gt;
&lt;br /&gt;
The third graph concerns the rotational speed of the ball. The &amp;quot;ball explodes&amp;quot; section is a reference to one of Randall's favorite equations, which is that an object cannot spin faster than the square root of its specific tensile strength. Spinning the ball any faster than this limit would cause the bowling ball to lose its structural integrity and explosively disintigrate. At particularly high speeds, the material of the ball would be flung outwards at a significant fraction of the speed of light, causing, as in graph #2, widespread destruction (possibly a reference to {{what if|92|One-Second Day}}.)&lt;br /&gt;
&lt;br /&gt;
The fourth graph in this comic illustrates a bowler's probability of a strike with a ball whose mass ranges from 10&amp;lt;sup&amp;gt;0&amp;lt;/sup&amp;gt; kg (2.2 pounds) to close to 10&amp;lt;sup&amp;gt;10&amp;lt;/sup&amp;gt; kg (over 22 billion pounds), and continues by indicating that balls even larger than that would cause &amp;quot;equipment damage&amp;quot; (up to 10&amp;lt;sup&amp;gt;20&amp;lt;/sup&amp;gt; kg) or the creation of a black hole (starting from around 10&amp;lt;sup&amp;gt;25&amp;lt;/sup&amp;gt; kg and up). The last entry on the x-axis of this graph is 10&amp;lt;sup&amp;gt;40&amp;lt;/sup&amp;gt; kg, which is about 5 billion times the mass of the {{w|Sun}}.&lt;br /&gt;
&lt;br /&gt;
By contrast, the United States Bowling Congress requires all bowling balls to weigh no more than 16 pounds (that is, a mass of no more than 7.257 kg), with no minimum weight. Hence, if the x-axis of the graph ran from, say, 0 to 8 kg, the graph might actually impart some useful information.&lt;br /&gt;
&lt;br /&gt;
The title text continues the trend of providing unhelpful information by stating that the optimal place to stand when trying to bowl a strike is inside the bowling alley. It is quite obvious that if one is to attempt to bowl a strike, they should stand near the pins, hence inside a bowling alley. The title text also mentions the possibility of &amp;quot;any establishment uphill from one&amp;quot; working, with a little luck. This suggests the possibility of rolling the bowling ball downhill, into the bowling alley (possibly ''through'' it) and into the pins.&lt;br /&gt;

; Aluminum foil&lt;br /&gt;
Why would aluminum foil be valuable? I can see how it would be hard to produce at the time. But how would it be used and why would people of the time see a lot of value in it? [[Special:Contributions/172.71.146.65|172.71.146.65]] 03:42, 5 November 2022 (UTC)&lt;br /&gt;
:Good question, but I'm persuaded the novelty and scarcity of metallic aluminium would have made it plenty valuable among those already wealthy enough to recognize what it was. Prussia was wealthy and Königsberg was its largest port city back then, so probably the mayor would have been able.
