Is there an easter egg here? Is 4.1083 a significant constant in some field?

:Dunno...but when I Googled it, it came up with a picture of a motorcycle I used to own - same vintage, same colour, same non-original aftermarket panniers - which was a little strange. Anybody else return any results centred around long-since-departed vehicles?

:I noted a proximity of "4.108(3)" to "42" and wondered if there was a connection ("how close can I get to 'the answer' without getting hammered for plagiarism or infringement?"). The comment below suggesting a link to the November 2023 "value" (= market capitalization) of X/Twitter is brilliant, but given that the market cap figure seems to have been posted on the day this comic was released, plus the evidence from comic 899, "coincidence" is probably the best explanation.[[Special:Contributions/162.158.186.118|162.158.186.118]] 18:27, 30 November 2023 (UTC)

The "narrowing down" of n might be a reference to a combinatorics problem Ron Graham was solving, managing to narrow down the dimensions of the hypercube with a certain property to be more than 6 and less than... Well, Graham's Number.

The variable 'n' is often used in computer programs to be a counter for some activity that is repeated 'n' times. 'n' may be user input or it might be a calculated value like the number of items in a list. So the code would be something like, for the integer 'i' starting at 1 and iterating up to 'n' number of times in whatever computer language is being used. In this case, 'n' would be limited to the maximum value of the specific integer type in that computer language on that machine.

2843: Professional Oaths

2023-10-19T16:59:53Z

162.158.186.118: /* Explanation */ better

{{comic
| number = 2843
| date = October 18, 2023
| title = Professional Oaths
| image = professional oaths.png
| titletext = Interpretations of the Hermeneutic Oath differ.
}}

==Explanation==
{{incomplete|Created by a HUMAN UNDER OATH.}}
The {{w|Hippocratic Oath}} is an "oath" of ethics taken by medical professionals, which includes the phrase "do no harm". [[Technically]], the exact phrase "first, do no harm" is not in the oath, but this meaning is implied.

The full Hippocratic Oath can be seen at {{w|Hippocratic Oath#Modern versions and relevance|the Wikipedia page.}}

Randall takes other words that sound similar to "hippocratic" and creates "oaths" for them.

# The word hyperbaric means "of or involving a gas at a pressure greater than normal", so thus a "hyperbaric oath" would indeed involve getting used to (acclimating to) a different pressure.
# Holographic refers to "holographic" projections as seen in media like "Star Wars", in which the image typically shimmers. Not to be confused with actual {{w|holograms}}.
# Histrionics is "exaggerated dramatic behavior designed to attract attention."{{actual citation needed}}
# {{w|Hydroelectricity}} is producing energy using water power, typically using {{w|turbine|turbines}}.
# A {{w|hippodrome}} is an arena that was historically used for chariot racing and horse racing.
# {{w|Hypnagogia}} is "the state immediately before falling asleep". The phenomenon of jolting awake just as one is about to fall asleep is sometimes referred to as a hypnagogic jerk.
# A {{w|hypergolic propellant}} is a type of rocket propellant which doesn't need a spark to ignite, and spontaneously combusts when mixing the parts together. Normal rocket propellant, such as RP-1 and liquid oxygen, requires some sort of initial spark to start the reaction.
# (title text) {{w|Hermeneutics}} is the study of interpreting texts, thus the "Hermeneutic Oath" could have several interpretations as to its meaning.

Talk:2841: Sign Combo

Theoretically you can get around this limitation by turning off the road before the sign and doing whatever maneuvers you need to out in the wide open area to the right or left of the road. It's not a U-turn if you're not on the road, and you didn't enter a restricted part of a road either, and didn't stop on the road. After which you calmly make a turn onto the road when traffic is clear. [[Special:Contributions/108.162.245.207|108.162.245.207]] 02:34, 14 October 2023 (UTC)

Take notice of the road markings too. At least here in Europe double white lines are not to be crossed. And they go past the point of the sign.--[[User:Henke37|Henke37]] ([[User talk:Henke37|talk]]) 07:06, 14 October 2023 (UTC)

:Double lines are also "do not cross" in America. And I think in this case it's supposed to be yellow, the dashed-and-solid combo indicates a one-sided passing zone into a lane with on-coming traffic, and double lines in general are only use to separate anti-parallel lanes of traffic, both of which use yellow. "Solid double white lines" do exist, but are only used in very specific cases. Near me, there's a very congested exit, and the solid double whites are used to indicate "no really, you should have switched lanes ages ago, it's too late now!", but since it isn't a Jersey barrier or a line of rods or even a full on median, nobody actually follows the rule. Anonymous 07:30, 14 October 2023 (UTC)

:: BTW in Europe, yellow lines are reserved for temporary use, and then take precedence over any existing white lines. Makes lots of sense, because there are so many construction sites here. (And the yellow lines are actually just adhesive tape.) --[[Special:Contributions/162.158.87.102|162.158.87.102]] 08:28, 14 October 2023 (UTC)

::: Back when elephants had fur, road markings in the USA were white. Starting in the 1950s, road crews throughout the USA began using yellow rather than white paint. From memory, it took about a decade for the transition to be completed, with more rural roads the last to go yellow. [[Special:Contributions/162.158.90.161|162.158.90.161]] 18:18, 14 October 2023 (UTC)

Speaking of lines ... in the USA, "Do Not Enter" signs on open roadways usually signal that the road ahead is one-way traffic coming at you. A driver is thereby warned (for example) not to enter the "exit" ramp of a freeway. However, the road striping indicates that passing is permitted for drivers proceeding forward past the sign ... which is nonsensical if the only legal traffic is coming at the viewpoint driver. I am reminded of the ancient comedy routine, "Somebody went to the Army-Navy store, got himself a sign, looked out his living room window, 'Look, Martha, we caught somebody!'" [[Special:Contributions/162.158.186.118|162.158.186.118]] 19:19, 14 October 2023 (UTC)

And I completely forgot why I was posting in the first place: I think there's good reason to create a full "traffic signs" or "road signs" tag, not just "traffic lights". I know there's a page with a very complicated "this is what the road ahead looks like" sign that just says "good luck", and of course there's "Next Five Miles" and "Ahead Stop". Thoughts? Anonymous 07:58, 14 October 2023 (UTC)

More thoughts: if you must not make a U-turn to the left, you should do it to the right.
And then return on the same lane, because of the double line.
And finally, the sign itself may be valid and not contradicting itself; it is your fault if you got on this road. ;) --[[Special:Contributions/162.158.87.102|162.158.87.102]] 08:28, 14 October 2023 (UTC)

In the Netherlands, the message on signs are only valid behind the sign (with the exception of the "precedence way" (voorrangsweg), where outside of built-up areas, the signs are after a junction (though technically... way before the ''next'' junction) , so a driver stopping /u-turning here wouldn't be violating anything except the double white lines.
Also, stopping out of necessity (e.g. the car in front is also stopped) is ''never'' illegal. [[User:IIVQ|IIVQ]] ([[User talk:IIVQ|talk]]) 09:06, 14 October 2023 (UTC)

:Stopping on a road with double white lines to your left may count as obstructing the road, which I can imagine to be illegal in many places? [[User:Gpvos|Gpvos]] ([[User talk:Gpvos|talk]]) 10:02, 14 October 2023 (UTC)

If I had to comply with these instructions, I would just put the car into reverse and argue that I was never "stopped". If I actually saw this in real life, I think I'd just slow down, put on my hazard lights, and make a u-turn when appropriate.[[User:Jsnider3|Jsnider3]] ([[User talk:Jsnider3|talk]]) 10:52, 14 October 2023 (UTC
