{{incomplete|Created by a DUTCH BOT - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This comic follows Cueball, Megan, Knit Cap and Ponytail as they begin to favor pedestrian-centered design. In the first panel, Cueball and Megan complain about the common problem many car-centric cities face about not having enough space for all the cars, and give the naive suggestion of making more space for cars. In the second panel, Knit Cap mentions how he is going to visit Amsterdam, a city known for its {{w|walkability}} and bike friendliness. Ponytail expresses concern over the popularity of cycling in the street presumably because cycling in the street is dangerous where she lives and so she expects it to be dangerous in Amsterdam.

In the third panel, Cueball discusses another problem many car-centric cities face which is that there are not a lot of bike paths. Since there is a limited amount of space on a street, cities face a dilemma on how much space they should allocate to pedestrians, bicyclists and vehicles. Car-centric cities often allocate the most space to cars, leaving less space for bikes and pedestrians. Many cities try and make up for a lack of space for bike lanes by allowing cyclists to cycle in the streets with the cars. This, however, is significantly more dangerous than a city having a dedicated bike lane which is why Ponytail was likely concerned in the second panel. (A recent study reported that painted bike lanes are more dangerous than no bike lane, and only protected bike lanes are safer: <span title="Conclusions: Protected bike lanes and buffered bike lanes had estimated protective effects on segments between intersections but estimated harmful effects at intersections. Conventional bike lanes had estimated harmful effects along segments and at intersections.">Garber, Michael D., et al: ''[https://www.sciencedirect.com/science/article/pii/S2214140523001056 Bicycle infrastructure and the incidence rate of crashes with cars: A case-control study with Strava data in Atlanta]''. Journal of Transport & Health, '''32'''. September 2023: Received 13 February 2023; Received in revised form 10 July 2023; Accepted 14 July 2023; Available online 11 August 2023. doi:[https://doi.org/10.1016/j.jth.2023.101669 10.1016/j.jth.2023.101669]) This danger was discussed more in the fifth panel as well.

Megan's comment in the sixth panel is likely referring to pickup trucks in addition to regular trucks. Many pickup truck owners care a lot about the distance their vehicle is off the ground and so they will either purchase a pickup truck with a high ground clearance or raise it themselves, resulting in what is known as a lifted pickup truck. Many people believe that a vehicle with higher ground clearance will keep them safe on the road, and while this is true (one editor learned the opposite, that the elevated center of mass reduced safety due to reducing the stable tipping angle, although they’ve certainly appreciated high clearance on unpaved roads), it comes at the cost of potentially hurting others who are in smaller vehicles or no vehicle at all. Alternatively, it could refer to many large tractor trailer cabs or garbage trucks that if you stand directly in front of the cab you can't see the driver and they can't see you. It is particularly dangerous for children.

{{w|Induced demand}} is an economic theory in which increasing the supply of a good or service causes the demand to rise faster than the increased supply, worsening the shortage. The most common example is traffic: some US cities have tried to alleviate traffic jams by widening the roads and highways, which incentivized more people to take up driving, thereby ''worsening'' their traffic jam problem. Conversely, other cities have tried removing traffic lanes or converting them to dedicated public transit lanes, and have claimed a reduction in traffic congestion. Among urban planners, this is known as the {{w|Downs–Thomson paradox}}.

Cueball's comment in the second-to-last panel that "anything that makes a city a worse place to drive in makes it a better place to live, short of scattering random tire spikes on the road" is a slight exaggeration. For example, a city that allows potholes to go unrepaired will make it more difficult to drive in, but could also make it more difficult for pedestrians to safely cross the street.

The title text references a cyberpunk book called "{{w|Snow Crash}}", by Neal Stephenson. An early scene in that book involves the equivalent of a skater using a magnet on a cable to attach onto the back of a pizza delivery vehicle. He swerves in order to dislodge her, she taunts him and attaches stickers to his vehicle.

=== What makes a city walkable? ===
As all of Europe''[citation needed]'' agrees, urban planning (or zoning) must be seamlessly integrated with public transport planning. The central truth is that everybody is a pedestrian for some time, which also includes car drivers. Crucially, the average pedestrian is willing to walk about 2000 ft from their home to the next public transport stop, and an additional 2000 ft between the last public transport stop and their workplace. Opportunities for shopping and eating should exist at every connecting station, with the connections scheduled in a way that it both allows changing to the connecting train/tramway/bus immediately - as well as buying groceries.

All roads should have a sidewalk, which, of course, costs area, but make the pedestrians' lives much easier. But then, not only roads impact walkability. In the United States, many places open to the public are, by municipal ordinances, forced to provide enough parking space for [https://www.youtube.com/watch?v=OUNXFHpUhu8 all customers at any given time], which leads to serious knock-on effects: Pedestrians must often cross a large and weather-exposed parking lot in order to shop. A building can often be only re-purposed if a neighboring building is bulldozed to create the necessary parking area. And tenants who live in an apartment, but do not own a car, are forced to pay for the parking space they do not need.

Another topic is subsidizing public traffic. Municipalities in Switzerland, for example, order bus connections - e.g. a hourly bus from 6 AM until 10 PM, and in exchange, they cover the deficit of any such connection. That way, families, who usually are better taxpayers, move to villages, and beginning with grade 5, 6 or 7, pupils can still easily commute to a district school.

:'''Typical urban planning opinion progression'''

:[Each panel is connected to a point on a timeline. Timeline is recognizable as the tread of a bicycle tire]

:Cueball: I wish there wasn't so much traffic to get into the city. They should put in more lanes.
:Megan: And more parking.
:Megan: Parking is so bad here.

:Knit Cap: I have to go to Amsterdam for work next week. I hear they all ride bikes there.
:Ponytail: Bikes are fine but people shouldn't ride them in the street! I worry I'm going to hit someone!

:Cueball: It would be nice if we had better transit options!
:Cueball: I tried a scooter. It was fun but I wish there were more bike paths.

:Megan: It's funny how widening roads to speed up traffic makes them more dangerous to walk near, making driving more necessary and creating more traffic.
:Megan: Really makes you think.

:Knit Cap: Visiting the Netherlands was cool!
:Knit Cap: Amsterdam is really neat.

:Cueball: We've ceded so much of our land to storing and moving cars, with the rest of us tiptoeing around the edges and making drivers mad for trespassing on "their" space.
:Cueball: Even though '''''we're''''' the ones in danger from '''''them!'''''

:Megan: Those giant trucks with front blind spots that keep hitting kids should be illegal.

:Knit Cap: We should be more like the Netherlands.
:Knit Cap: They design their streets to prioritize...

:[Cueball is frustrated.]
:Cueball: The problem is car culture. It's systemic.
:Cueball: I don't know if we can fix it.

:[Megan’s arms are thrown out, and her hair is bedraggled.]
:Megan: People approach road planning decisions from the point of view of drivers because that's how we're used to interacting with the city, so we make choices that make it more car-friendly.
:Megan: It's a vicious cycle.

:[Knit Cap is walking around with two Dutch flags raised in his hands.]
:Knit Cap: '''''Netherlands! Netherlands! Netherlands! Netherlands!'''''

:Cueball: Anything that makes a city a worse place to drive in makes it a better place to live, short of scattering random tire spikes on the road.

:Megan: Honestly, I think the city council should consider the tire spikes thing.

172.69.79.154: That's a *huge* image. And really it needs not to appear 'inline', either, but making a first fix to not really mess with browser windows...

Boop! [[User:PotatoGod|PotatoGod]] ([[User talk:PotatoGod|talk]]) 07:53, 2 September 2023 (UTC)

Came here to find out what in the heck ‘boop’ has to do with anything, learned absolutely nothing (autospell changed it to “book” so I’m not alone). [[Special:Contributions/172.71.154.76|172.71.154.76]] 08:17, 2 September 2023 (UTC)
:There's a link there now (not sure when anyone added it, might have been after your query) which satisfies me somewhat. Seems to be a playful tagging/"you're it!" sort of thing, though, like "punch buggy <yellow/etc>", it's not something I really knew of though probably appears to be in Randall's childhood/whatever cultural background and that's good enough for me. [[Special:Contributions/172.69.79.152|172.69.79.152]] 09:53, 2 September 2023 (UTC)
::I agree that "boop" needs an extra explanation for non native speakers of English. The link is useful (thanks to whoever added it) but the Wiktionary definition alone is too terse to get the pun.--[[User:Pere prlpz|Pere prlpz]] ([[User talk:Pere prlpz|talk]]) 11:54, 2 September 2023 (UTC)
:I added the wikitionary link and I was not entirely happy with it, but it's a starting point. Please do improve it. To me, "boop" is a friendly pat on the nose that one might do to, especially, a dog's nose; see https://www.hillspet.com/dog-care/play-exercise/do-dogs-like-dog-boops?. Definitely more affectionate and less aggressive than the "punch buggy" action (which can get out of hand), or even tagging. I was surprised that https://en.wikipedia.org/wiki/Boop did not have a mention of this, not even on the talk page; yeah, it's not the most encyclopedic of topics, but discussing social behaviors is beyond the bounds of wiktionary, and Urban Dictionary isn't a great place to cite to (even if it were helpful). [[User:JohnHawkinson|JohnHawkinson]] ([[User talk:JohnHawkinson|talk]]) 12:26, 2 September 2023 (UTC)
::To the non-native English speakers, it's basically just playfully, gently touching a dog or other animal/pet on the nose while saying "Boop". Like "I got your nose." Not really petting/stroking; just a form of play or affection. I'm not surprised there isn't a lot documented on this as it's not really a "thing". Kind of like Randall's use of pew pew pew noises while pretending to fire a ray gun. You understand what he's doing and may have done it yourself, but it's not the kind of thing you expect to find on Wikipedia. :) [[Special:Contributions/172.71.254.125|172.71.254.125]] 15:40, 2 September 2023 (UTC) Pat

I was actually curios as whether any eye had ever seen a 400 million old fossil. Had to look it up to see when the first eyes evolved. But seems it was around [https://www.scienceworld.ca/stories/eyes-how/ 550 million years ago], so some eyes may have seen the animal that turned in to the fossil Cueball now sees. ;-) --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 12:47, 3 September 2023 (UTC)

I thought that the rock with the trilobite looks like a remote control button that makes a "beep" or "boop" when you push it. Or alternatively an infant's toy that has a button that makes a sound like a clown's nose. So Cueball is pressing the trilobite and vocalizing the "boop" sound that would be expected from these objects. Although "booping" a child's nose is a thing ... although it seems very rude ... I did not associate the fossil rock with the trilobite with noses, but I did associate it with remote control devices that have a flat pad with a button (or many buttons) on it. [[User:Rtanenbaum|Rtanenbaum]] ([[User talk:Rtanenbaum|talk]]) 13:26, 3 September 2023 (UTC)

Here is an example picture of a trilobite which has two large eyes and a centre area which might be booped. The fossil is 3D meaning it is not flat.
[[File:trilobite.jpg|300px]]
In contrast a fossil fish will often be flat, almost 2D, and show only one eye. Many people in North America do not like to see the head of a fish and so the head of a fossil fish can also seem odd.

==Explanation==
This was the fourth comic originally posted to [[LiveJournal]]. The previous one was [[3: Island (sketch)]], and the next one was [[1: Barrel - Part 1]]. It was among the [[:Category:First day on LiveJournal|first thirteen comics]] posted to LiveJournal within 12 minutes on September 30, 2005, on the first day of the xkcd LiveJournal account.

This comic does not present a particular point, it's just a picture drawn by [[Randall Munroe|Randall]]. ''{{w|The Little Prince}}'' (in French ''Le Petit Prince'') is a novella written by {{w|Antoine de Saint-Exupéry}} in 1943, about the titular Little Prince, who lives on an asteroid and visits other inhabited asteroids and eventually the Earth. The book is filled with drawings of the asteroid, the prince, and the travels they make. It is noted how, on occasion, {{w|Adansonia|baobab trees}} can begin to grow on these asteroids, and should they not be immediately uprooted, the growth of their roots would tear the asteroid apart. In this drawing, the roots are encircling the sphere rather than piercing it, as the book describes. ''The Little Prince'' would later be referenced in the ''[[what if? (blog)|what if?]]'' article ''{{what if|26|Leap Seconds}}'', in [[618: Asteroid]], and in [[1350: Lorenz]] at [https://imgs.xkcd.com/comics/a1-2014/VgSdMz8OAHQ8w5Ee432f5Q.png the end] of the space trip branch.

2817: Electron Holes

2023-08-20T21:14:38Z

172.69.79.154: /* Explanation */ Actually, as it's already linked above, we don't need another one (even if we're keeping the blockquote insertion)

{{comic
| number = 2817
| date = August 18, 2023
| title = Electron Holes
| image = electron_holes_2x.png
| imagesize = 295x331px
| noexpand = true
| titletext = They tried to report me to the authorities, but because I had the device they couldn't charge me.
}}

==Explanation==
{{incomplete|Created by a BEAM OF EXCITONS - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
An {{w|electron hole}} is a quasiparticle denoting a ''lack'' of an electron. Creating a beam that is made out of a lack of a thing is not possible{{citation needed}}, otherwise we'd have "dark beams". It should be noted however, that a hole in the QED vacuum is a real particle, known as the positron. See the {{w|Dirac sea}}.

Wikipedia gives a good basic explanation of the concept of the "electron hole":

<blockquote>[A]n electron hole (often simply called a hole) is a quasiparticle denoting the lack of an electron at a position where one could exist in an atom or atomic lattice. Since in a normal atom or crystal lattice the negative charge of the electrons is balanced by the positive charge of the atomic nuclei, the absence of an electron leaves a net positive charge at the hole's location.

Holes in a metal or semiconductor crystal lattice can move through the lattice as electrons can, and act similarly to positively-charged particles. They play an important role in the operation of semiconductor devices such as transistors, diodes (including light-emitting diodes) and integrated circuits. If an electron is excited into a higher state it leaves a hole in its old state. . . .

In solid-state physics, an electron hole (usually referred to simply as a hole) is the absence of an electron from a full valence band. A hole is essentially a way to conceptualize the interactions of the electrons within a nearly full valence band of a crystal lattice, which is missing a small fraction of its electrons. In some ways, the behavior of a hole within a semiconductor crystal lattice is comparable to that of the bubble in a full bottle of water.</blockquote>

In this cartoon, the physicist is upset that the idea of the electron hole beam doesn't "make sense" - because a beam consisting purely of things that are "missing" doesn't seem possible; electron holes only exist in the context of a background field of electrons in which just a few are missing - yet the beam is still working to destroy her belongings (or at least create dramatic visual effects) and eventually she resorts to exclaiming simply "Stop it!"

The caption below the comic states that physicist''s'', plural, were angry about this device, implying that this is not the first physicist whose lab he has interfered with. It also implies that the off-screen character—likely [[Beret Guy]], considering his history of seemingly impossible feats and powers—is not a physicist, notably separating them from {{w|Randall Munroe}}, who is. The physicists are also likely angry that they themselves could not come up with such a device, as well as that something as groundbreaking and innovative (as well as seemingly impossible) is being used solely for the purpose of creating chaos.

The title text plays on a double meaning of "charge". When the word is used with "authorities", it's an accusation. However it can also refer to an electric charge. The implication is that the authorities are trying to charge him with electrons (which carry a negative electric charge), but due to the device he can {{w|Carrier generation and recombination|recombine}} the electrons with his electron holes, thus making the authorities unable to "charge" him.

There are little '+' signs distributed along the beam and in the circles around the printer, though they're much easier to see in the higher-resolution version of the strip that's displayed if one zooms in on the original comic page.]
