1677: Contrails
| Contrails |
 Title text: Astronomy (or "astrology" in British English) is the study of ... |
Explanation
Contrails (short for "condensation trails") are trails of vapor produced by aircraft exhaust, trailing the airplane. They are formed from water condensing on jet fuel exhaust particles, some impurities of which provide bases for ice crystals to accumulate on. Some can dissipate in minutes, but others can last for hours or even longer, depending on the temperature and wind conditions at that particular altitude. The chemtrail conspiracy theory claims that contrails lasting unusually long are actually chemical or biological agents sprayed into the air for sinister purposes. There is no evidence such a thing is happening.
Here, White Hat, presumably speaking with a British accent, notices that there are a lot of contrails in the air. Cueball corrects him, saying that in American English, contrails are called chemtrails, which is, of course, incorrect.
This is a comic in the My Hobby series. Some of these comics involve Cueball giving misleading information about pedantic terms, such as 1405: Meteor. Another of these comics, 966: Jet Fuel, even mentions chemtrails, saying that they are made of mind-control agents carried on board the planes that makes them.
The title text implies that astronomy and astrology are synonymous, with astrology being the term used in British English. However, this is incorrect. Though both involve studying celestial objects, astrology is the pseudoscience that interprets positions of celestial objects as having influence on human affairs, while astronomy is the scientific study of celestial objects on a universal scale.
The joke is that British English and American English often call the same object with different terms, and one can often learn new words for a simple thing. This, however is not the case in this comic; contrail and chemtrail do not refer to the same thing, the latter being only a subtype of the former. And it being xkcd, we can assume that chemtrail is a term that is frowned upon. Thus the comic states it as misinformation.
The title text includes a similar situation: Astronomy is the scientific study of things in outer space, like stars, planets, and galaxies. Astrology, however, is a system that infers a persons personalities and characteristics from zodiacs on the persons birth date. the zodiac being the constellation assigned to that period of time in a year. The same system can also derive predictions about future, especially that of a relationship. Some would argue that astrology shows statistical values, but it is hardly science by the standards of scientific study.
Given that the "American English" version is the conspiracy theory one for contrails/chemtrails, while who confuses astronomy and astrology is not fully clear, it is possible that the rest of the explanation of the astronomy vs astrology text would describe astrology. In that case, this could be a comment on the educational status in the US vs the UK, where conspiracy theories and superstition (astrology) are much more prominent in the US than in the UK (or Europe in general).

Aside: worst name ever for university department: Astronomy and Cosmology - it's almost as if they want people to make the association... 141.101.104.20 10:58, 6 May 2016 (UTC)
Love the title text, you can choose to laugh or take offence irrespective of where you call home. Which you do says more about you than the text. Toltec (talk) 11:41, 6 May 2016 (UTC)
Worth noting that 'contrails' is itself a North Americanism? 108.162.229.111 12:03, 6 May 2016 (UTC)
The final paragraph does not logically follow from the comic or from the explanation. He's hooking different pseudoscience terms on different cultures (astrology on the UK and chemtrails on the US) so the comic doesn't take a stance on which country's educational system is better or more prone to superstitions than the other. 108.162.245.106 15:04, 6 May 2016 (UTC)
I've always called them vapour trails (north west England) -- 141.101.98.137 (talk) (please sign your comments with ~~~~)
- I can tell. I didn't know the english even put a 'u' in 'vapor'. 108.162.237.178 17:34, 19 December 2016 (UTC)
🐍 Its Canadian usage as well. Rush has an album by that name, and a song titled, and referencing them in the lyrics. video These Are Not The Comments You Are Looking For (talk) 20:28, 7 May 2016 (UTC) (Can't figure out how to prevent the font from changing)
The comic reminded me of the Hungarian Phrasebook sketch from Monty Python - basically someone who enjoys causing confusion for its own sake between speakers of (in this case, slightly) different languages. 108.162.237.175 18:21, 6 May 2016 (UTC)Pat
I grew up (US Midwest then Northwest) calling them "plane tracks" (by extension from "train tracks," I suppose) and later, "jet trails." I don't think I've ever /heard/ (as opposed to read) either "chemtrails" or "contrails," but they're both far outside my normal areas of work/interest, that there never would have been a reason for them to come up or pass by. 108.162.221.98 19:01, 6 May 2016 (UTC)

Contrails is more of a technical term, I think. I grew up in the southeast and currently live in the midwest and I only ever hear them called jet trails or vapor trails, only rarely does someone say contrails, and they're usually fairly technical people. 108.162.219.43 02:34, 8 May 2016 (UTC)
- Born and raised in Colorado: always heard "contrails". L-Space Traveler (talk) 12:05, 30 June 2023 (UTC)
Should we mention the alternate meanings of "Con", especially Confidence trick would seem relevant here. Condor70 (talk) 06:42, 9 May 2016 (UTC)
- I don't think that's relevant at all, the term "contrail" as mentioned is from "condensation", i.e. "to condense". I don't think a full etymology is merited on this page.
- On the other hand: A con trick with a contrail? Sounds like being a reasonable pun... 162.158.158.211 16:56, 7 May 2020 (UTC)
