&lt;div&gt;{{comic&lt;br /&gt;
| number    = 1042&lt;br /&gt;
| date      = April 13, 2012&lt;br /&gt;
| title     = Never&lt;br /&gt;
| image     = never.png&lt;br /&gt;
| titletext = I'll never forget you--at least, the parts of you that were important red flags.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
This comic plays with that some phrases are generally interpreted as communicating positive sentiments, although they strictly are ambiguous.&lt;br /&gt;
&lt;br /&gt;
[[Cueball]] is mulling over a previous relationship. Usually when someone says something like &amp;quot;I will never have with anyone what I had with {{w|Nomen nescio|NN}}&amp;quot; it implies that the couple had something so good that it could never be replaced. But when he thinks &amp;quot;Thank God&amp;quot;, it is suddenly implied that the relationship was so horrible he's thankful he'll never have to experience it again.&lt;br /&gt;
&lt;br /&gt;
The title text goes along the same line: &amp;quot;I'll never forget you&amp;quot; is usually positive – but then it becomes clear that it is the {{w|red flag (signal)|red flags}}, the warning signs about the person that they would not be a good fit for a serious relationship and marriage, that he'll never forget.&lt;br /&gt;
&lt;br /&gt;
There is a similar twist in comics [[71: In the Trees]] and [[334: Wasteland]].&lt;br /&gt;
&lt;br /&gt;

This comic jokingly proposes a situation in which chemists have discovered and catalogued every single possible molecule. Thus they declare they have &amp;quot;completed chemistry.&amp;quot;&lt;br /&gt;
&lt;br /&gt;
In real life the number of ways to arrange atoms into molecules is growing combinatorial with the number of atoms in a molecule. Hence the number of possible combinations approaches rather quickly the number of particles in the observable universe making the full cataloging of all molecules impossible. Thus, a &amp;quot;final molecule&amp;quot; cannot be reached. In addition, chemistry is the study of the interaction and changing states of atoms and molecules, not simply the cataloging of all specimens of molecule. Even if we had a list of every molecule, there are a far greater number of ways to continue studying them, so the field would still be nowhere near completed.  To quote the famous chemistry researcher, educator, businessman and philanthropist Walter White, &amp;quot;Chemistry is the study of change&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
This is reminiscent of biology's focus in previous centuries on simply cataloging the species on Earth.&lt;br /&gt;
&lt;br /&gt;
Further, the goal of science is not to &amp;quot;complete&amp;quot; a field, but to understand it better and better.  No scientific field is considered fully understood.&lt;br /&gt;
&lt;br /&gt;
Putting Biology at 93% and Physics at 98% is patently absurd. As mentioned in the comic, we don't even know how many kinds of ants there are yet. When J.B.S Haldane, founder of the field of population genetics, was asked what science had taught him about God &amp;amp;mdash; he reportedly said &amp;quot;God is incredibly fond of beetles.&amp;quot; Insects aside, fundamental and important problems such as what genes promote which traits, the nature of cognition, and the mechanism behind several diseases remain complete mysteries. We know less about our own ocean floor than we do about the surface of Mars. Needless to say, Biology is nowhere close to 93% solved. As for Physics, questions such as &amp;quot;what the actual hell is dark matter?&amp;quot; and &amp;quot;how do we unify the four fundamental forces?&amp;quot; and &amp;quot;how do we make nuclear fusion possible on earth?&amp;quot; and &amp;quot;how fast does light travel in one direction?&amp;quot; make it clear that the field still has a long, long way to go.&lt;br /&gt;

This comic jokingly proposes a situation in which chemists have discovered and catalogued every single possible molecule. Thus they declare they have &amp;quot;completed chemistry.&amp;quot;&lt;br /&gt;
&lt;br /&gt;
In real life the number of ways to arrange atoms into molecules is growing combinatorical with the number of atoms in a molecule. Hence the number of possible combinations approaches rather quickly the number of particles in the observable universe making the full cataloging of all molecules impossible. Thus, a &amp;quot;final molecule&amp;quot; cannot be reached. In addition, chemistry is the study of the interaction and changing states of atoms and molecules, not simply the cataloging of all specimens of molecule. Even if we had a list of every molecule, there are a far greater number of ways to continue studying them, so the field would still be nowhere near completed.  To quote the famous chemistry researcher, educator, businessman and philanthropist {w:Walter White} &amp;quot;Chemistry is the study of change&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
This is reminiscent of biology's focus in previous centuries on simply cataloging the species on Earth.&lt;br /&gt;
&lt;br /&gt;
Further, the goal of science is not to &amp;quot;complete&amp;quot; a field, but to understand it better and better.  No scientific field is considered fully understood.&lt;br /&gt;
&lt;br /&gt;
Putting Biology at 93% and Physics at 98% is patently absurd. As mentioned in the comic, we don't even know how many kinds of ants there are yet. When J.B.S Haldane, founder of the field of population genetics, was asked what science had taught him about God &amp;amp;mdash; he reportedly said &amp;quot;God is incredibly fond of beetles.&amp;quot; Insects aside, fundamental and important problems such as what genes promote which traits, the nature of cognition, and the mechanism behind several diseases remain complete mysteries. We know less about our own ocean floor than we do about the surface of Mars. Needless to say, Biology is nowhere close to 93% solved. As for Physics, questions such as &amp;quot;what the actual hell is dark matter?&amp;quot; and &amp;quot;how do we unify the four fundamental forces?&amp;quot; and &amp;quot;how do we make nuclear fusion possible on earth?&amp;quot; and &amp;quot;how fast does light travel in one direction?&amp;quot; make it clear that the field still has a long, long way to go.&lt;br /&gt;

| image     = flag_map_sabotage.png&lt;br /&gt;
| titletext = Delaware hopes to explore the western edge of areas marked with the Belgian flag, once the tornadoes die down.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|This particular explanation could use a visual aid. Perhaps a world map where Canada had adopted this flag? - Please change this comment when editing this page. Do NOT delete this tag too soon.}}&lt;br /&gt;
&lt;br /&gt;
The comic refers to a type of map that colors countries using the national flag designs; see [https://i.pinimg.com/originals/41/0f/36/410f3661d1cee3b255b82a111f99d242.jpg here] for such a map of Europe. Randall proposes a new flag which is specifically designed to troll such maps.  Most obviously, the flag includes its own legend, which uses multiple common flag colors to indicate random regional attributes.  Hence, the mere act of placing this flag on a map would cause people to misinterpret this legend as applying to the entire map, giving wildly false information about regions of other countries. This trick is reminiscent of [[327: Exploits of a Mom]], with Mrs. Robert's son &amp;lt;code&amp;gt;Robert'); DROP TABLE Students;--&amp;lt;/code&amp;gt;. &lt;br /&gt;
&lt;br /&gt;
In addition to the legend, the flag consists of two red fields, one of which has an irregular-shaped border, the other of which is a straight line. The irregular shape is similar to a geographical border based on natural features (such as rivers and coastlines), while borders which are not based on such features tend to be straight lines.  Red is the most common color on national flags, so if any bordering country had red on their flag, it would risk bordering these red fields, confusing where the border lay (as well as designating the entire red region as &amp;quot;greater Delaware&amp;quot;).  If this flag is intended for the USA (although the text mentions &amp;quot;our new country&amp;quot;), the red regions would be continuous with the red strips on both sides of Canada's flag and the red field on the right of Mexico's flag, disguising the border still further.  &lt;br /&gt;
&lt;br /&gt;
The title text refers to the flag of Belgium, which consists of three vertical stripes in the order (left to right) black, yellow, and red. The western part of Belgium would, according to the legend, be unexplored, while the eastern part would be Greater Delaware. The middle would therefore be a tornado zone separating the unexplored area from Greater Delaware. Depending on how the flags are aligned it might be possible to explore from the south, where the blue-white-red stripes of the French flag contain another piece of Greater Delaware that may be conveniently located to help said exploration. Exploring from the Netherlands (red, white, and blue horizontal stripes) is not viable as rebel forces are positioned between Greater Delaware and the unexplored region. &lt;br /&gt;
&lt;br /&gt;
This is not the first time Randall has made a flag for a new country! See [[1815: Flag]]&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{w|Ingenuity_(helicopter)|Ingenuity}} is a drone-like helicopter deployed to the surface of Mars. It rode on the underside of the Perseverance rover and at the time of publication its protective housing had been released from the rover and it was being prepared for a flight in early April. The helicopter is supposed to take off after the rover fully releases it and clears its takeoff trajectory.&lt;br /&gt;
&lt;br /&gt;
The comic projects what might happen if the mission controllers activated the helicopter early. In this case, the process is approaching the point of detaching the part-deployed Ingenuity. Ponytail and Cueball are present in mission control when Cueball trips and hits a button that clearly triggers the Ingenuity drone to take off. Perserverance, still firmly above/attached is seen to easily ride atop it. The rover exclaims &amp;quot;Wheee!&amp;quot;, presumably from excitement or happiness.&lt;br /&gt;
&lt;br /&gt;
In the title text, some character discovers powered flight is easier on Mars, which contradicts our current understanding [https://www.youtube.com/watch?v=GhsZUZmJvaM that powered flight is very difficult on Mars]. Mars may have less gravity, but Mars's atmosphere is 1% the density of Earth's. [https://www.youtube.com/watch?v=aYe3sIaNHVs It's so thin that you couldn't move a feather with a fan.] This is why the character mumbles his explanation of the science, because they know any explanation doesn't actually make sense.&lt;br /&gt;
&lt;br /&gt;
The total mass of the two vehicles is about 556 times that of the helicopter alone, meaning the unexpected lift effect 'described' would have to be several hundred times more effective than that anticipated, depending upon the factor of overdesign already built in to avoid an expensive marginal failure. It also seems to be trivially easy to balance the extremely top-heavy loading upon the small solar-panel that tops out the counter-rotating coaxial blades, which adds yet more questions of both the dynamic and structural performance, never mind questions about the available power to accomplish this and the later possibilities to recharge.&lt;br /&gt;
&lt;br /&gt;
It is not the first time that we have seen a Mars vehicle [[1504|vastly exceed expectations]] in these pages.&lt;br /&gt;
&lt;br /&gt;
It is also not the first time a character has caused an incident by [[1620|tripping and hitting a control panel]].&lt;br /&gt;

&lt;br /&gt;
It is not the first time that we have seen a Mars vehicle [[1504|vastly exceed expectations]] in these pages.&lt;br /&gt;
&lt;br /&gt;
It is also not the first time a character has caused an incident by [[1620|tripping and hitting a control panel]].&lt;br /&gt;
