==Explanation==
{{incomplete|This page was created recently by HARMING THE ENVIRONMENT. Don't remove this notice too soon.}}
[[Black Hat]] and [[Cueball]] are outside Black Hat's house discussing the {{w|solar panel}}s he has recently installed on the roof. (Or alternatively outside another house, e.g. Cueball's, with its solar panels having initiated the comparison.) Being a [[72: Classhole|classhole]], Black Hat is attempting to live in a way that will maximize his negative impact on the environment. Cueball asks why he has installed solar panels, since he knows that Black Hat, and that he has described himself as anti-'{{w|renewable energy|renewables}}'. Black Hat responds that, as much as he'd prefer an option that harmed the planet more, solar power ({{w|photovoltaics}} and/or {{w|solar thermal energy}}) is simply the cheapest option and his budget is incapable of supporting anything else.

Black Hat's words in panel 3, that "the technology just isn't there and the cost is too high", is an oft-repeated excuse for those sticking with {{w|fossil fuel}} use rather than potentially deploy renewable energy technology, such as solar panels. When solar panel technologies were in their infancy, their costs were very high,[https://www.iea.org/data-and-statistics/charts/evolution-of-solar-pv-module-cost-by-data-source-1970-2020] pricing out most uses of them; but now solar panels are mass-produced, and it has become [https://www.wri.org/insights/growth-renewable-energy-sector-explained more affordable] for households to put solar panels on their rooftops, so the excuse has lost much of its validity. Nowadays this excuse is commonly used to justify technological inertia.

This may also be reference to the high oil/gasoline prices recently, going up over 30% in the past two weeks.

In the end, Black Hat claims that he can try to 'make up for this' by using the saved money to buy industrial waste and burn it in his backyard. Cueball responds with a knowing comment about 'carbon onsets'. This is a play on {{w|Carbon offsets and credits|carbon ''offsets''}}: certificates used for demonstrating mitigation of one's own carbon footprint, by effectively crowd-funding larger projects that are {{w|Carbon dioxide removal|'carbon negative'}} but are difficult to properly coordinate directly and individually. Carbon offsets represent emission reductions or captures happening elsewhere, and can be used to ''offset'' emissions caused by the user of the credit. This is rather than just relying upon random altruistic third parties to put the effort and finance into such a scheme to counteract others' care-free carbon emissions, or to allow a way to reward those who would indeed just do this off their own back.

Black Hat does the reverse, causing extra environmental harm to offset (or "onset", as Cueball calls it) the good reluctantly done by him by using solar panels instead of an {{w|oil burner|oil furnace}}. This doesn't really make sense since it's not clear what target he would be trying to 'onset' to; there is no 'ideal' level of emissions that he would be trying to achieve, although one can assume that he'll be aiming to be at least the wrong side of 'carbon neutral'. While the solar panels will have a much lower carbon footprint than the oil furnace, they will still have had some, in manufacture, and other options (such as burning coal) could provide him with even more emissions than the oil.

The title text is a spin on a standard argument about personal responsibility in tackling environmental issues, distorted through the perspective of Black Hat. Low amounts of action to address personal impact is sometimes excused by pointing out that it will be a 'drop in the ocean' relative to the scale of the problem, and suggesting that only action at a global institutional level can really address it. Black Hat believes (correctly) that policy and other systemic change can cause bigger damage than just him burning industrial waste, and is excited about the potential for this to change things for the worse. This is ironic, because ingrained institutional and systemic factors have played a significant role in ''causing'' the problems we now have, and holding up the finding of solutions to them.

This is one of the few comics [[Black Hat]] appeared in in the 3000s, the others being [[3057]], [[3067]], [[3105]], & [[3202]].

:Cueball: Wait, you got solar panels?
:Cueball: I thought you were against renewables.

:[Zoom to show only Cueball and Black Hat.]
:Black Hat: Oh, definitely. I hate the environment and want to harm it as much as possible.
:Black Hat: I'd '''''love''''' to have an oil furnace.

Climbing up the pole is already forbidden as a direct result of people actually doing that with a normal pole; specifically neither hand may hold the pole above the initial position of the upper hand.

Also, there may be less need of a rule change, because, except for solution 1, none of these work in a 3D world. A pole with snall diameter can be approximated to have measure 0 in a 3D world. In other words, the challenge of a pole vault lies therein to accomblish a task with a n-2 dimensional device in a world with n dimensions.

Question: Would a correct interpretation be "if a champion jumping frog were to be located just under 1.5 light-days from earth, and if there we're no other gravitational bodies nearby, and if said frog then performed its mightiest jump directly away from earth, then the frog would eventually be overcome by Earth's gravitational field and would eventually land on Earth's surface"? [[User:Pgn674|Pgn674]] ([[User talk:Pgn674|talk]]) 06:26, 16 December 2025 (UTC)
:I guess that is exactly how it should be interpreted. Or more interesting if it was just outside this radius and somehow could gain exactly 4,5 m/s extra speed then it would escape Earth (if there was anything to push of against that was heavy enough to move basically only the frog forward, then that would change the mass behind the frog so... That was why I wrote gain exactly rather than jump). --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 07:36, 16 December 2025 (UTC)

: or its mightiest jump in any direction (that doesn't cause it to crash through the Earth) since the escape speed is the same in all directions (relevant xkcd:https://what-if.xkcd.com/68/ ) --[[Special:Contributions/178.197.223.163|178.197.223.163]] 09:21, 16 December 2025 (UTC)

The only two variables are rjf and M, so plotting a 2 axis graph plotting the relationship between M and rjf should be possible. [[User:Zabadoh|Zabadoh]] ([[User talk:Zabadoh|talk]]) 08:20, 16 December 2025 (UTC) [''You sign '''after''' your contribution'']

As frogs usually collect on the surface of worlds {{cn}}, the *surface* escape velocity is most important. The crossover point for a planet with earth-like density (5515 kg/m³) is 2.6km, above that, the rjf falls below the surface, and the planet can accumulate frogs. Smaller bodies are, however, usually less dense; an interesting borderline candidate is Chicxulub, which had an rjf of 3-4km, and a radius of 5-6km so could have just about held onto its frogs, for a while at least. [[User:JeffUK|JeffUK]] ([[User talk:JeffUK|talk]]) 10:04, 16 December 2025 (UTC)

It would be interesting to look at the Rjf values ''of a frog'', to consider where new limits are put upon the frog for M-masses that aren't totally dominating the scenario of "frog leaves mass"... [[Special:Contributions/82.132.237.93|82.132.237.93]] 11:03, 16 December 2025 (UTC)

I interpreted it as a reference to the Mark Twain short story The Celebrated Jumping Frog of Calaveras County. [[User:Gustaveeiffel314|Gustaveeiffel314]] ([[User talk: Gustaveeiffel314|talk]]) 12:25, 16 December

I also suspected an allusion to Twain's short story, but then I read it at archive.org/details/celebratedjumpin00twai and found no parallels. The earth's radius wasn't the problem, it was 5 pounds of quail shot. That frog didn't land with a "plop" but "as solid as a gob of mud." There is no mention of "champion" in the story. The 1865 population of Calaveras County (post Gold Rush) was down below 15,000. That is, the frog shown in #3181 probably came from somewhere else that really knows how to breed frogs with muscular legs, maybe France. Before I risk overthinking this, I'm going to conclude that #3181 is not a Twain reference. [[User:Bismuthfoot|Bismuthfoot]] ([[User talk:Bismuthfoot|talk]]) 14:37, 16 December 2025 (UTC)

Erm, the current text has a statement that rjf < 4.5m/s for other planetary bodies. Seems like it is mixing measurements, a radius would be a distance, not a velocity. It might be trying to say that other planetary bodies have an ESCAPE VELOCITY of more than 4.5 m/s, so jumping frogs on the surface of those planetary bodies couldn't get out of that planet's gravity well. ~~{{unsigned ip|57.140.32.36|15:53, 16 December 2025}}

I disagree with the point about the flawed argument of frogs all being on earth. With a simple assumption that no aliens have transported a frog off world, basic taxonomy says that anything resembling a frog on another planet would infact not be a frog and would be a result of convergent evolution. I also think that aliens moving stuff around is not a common inclusion in physics formulas. So perhaps still falwed but not as strongly flawed as implied in the main text.

: That doesn't negate the point that ''if'' a frog was loose in space, it could be trapped in the gravity well of another planet and end up there rather than Earth.

:From a general relativity point of view the ISS is not really different from the surface of Earth.

:In fact, you have to do most of the work to ''get to'' ISS's orbit (far more than 'merely' getting to its altitude), 9.4km/s (ish). You only need about ~1.7km/s more to escape Earth entirely.
:Not quite within Champion Frog reach, of course.

Are the escape velocity figures in that table...even remotely accurate? For instance, the table claims Eris's escape velocity is 4.43 meters per second, while Wikipedia says 1.38 ''kilometers'' per second.

Question: Would a correct interpretation be "if a champion jumping frog were to be located just under 1.5 light-days from earth, and if there we're no other gravitational bodies nearby, and if said frog then performed its mightiest jump directly away from earth, then the frog would eventually be overcome by Earth's gravitational field and would eventually land on Earth's surface"? [[User:Pgn674|Pgn674]] ([[User talk:Pgn674|talk]]) 06:26, 16 December 2025 (UTC)
:I guess that is exactly how it should be interpreted. Or more interesting if it was just outside this radius and somehow could gain exactly 4,5 m/s extra speed then it would escape Earth (if there was anything to push of against that was heavy enough to move basically only the frog forward, then that would change the mass behind the frog so... That was why I wrote gain exactly rather than jump). --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 07:36, 16 December 2025 (UTC)

: or its mightiest jump in any direction (that doesn't cause it to crash through the Earth) since the escape speed is the same in all directions (relevant xkcd:https://what-if.xkcd.com/68/ ) --[[Special:Contributions/178.197.223.163|178.197.223.163]] 09:21, 16 December 2025 (UTC)

The only two variables are rjf and M, so plotting a 2 axis graph plotting the relationship between M and rjf should be possible. [[User:Zabadoh|Zabadoh]] ([[User talk:Zabadoh|talk]]) 08:20, 16 December 2025 (UTC) [''You sign '''after''' your contribution'']

As frogs usually collect on the surface of worlds {{cn}}, the *surface* escape velocity is most important. The crossover point for a planet with earth-like density (5515 kg/m³) is 2.6km, above that, the rjf falls below the surface, and the planet can accumulate frogs. Smaller bodies are, however, usually less dense; an interesting borderline candidate is Chicxulub, which had an rjf of 3-4km, and a radius of 5-6km so could have just about held onto its frogs, for a while at least. [[User:JeffUK|JeffUK]] ([[User talk:JeffUK|talk]]) 10:04, 16 December 2025 (UTC)

I also suspected an allusion to Twain's short story, but then I read it at archive.org/details/celebratedjumpin00twai and found no parallels. The earth's radius wasn't the problem, it was 5 pounds of quail shot. That frog didn't land with a "plop" but "as solid as a gob of mud." There is no mention of "champion" in the story. The 1865 population of Calaveras County (post Gold Rush) was down below 15,000. That is, the frog shown in #3181 probably came from somewhere else that really knows how to breed frogs with muscular legs, maybe France.

Erm, the current text has a statement that rjf < 4.5m/s for other planetary bodies. Seems like it is mixing measurements, a radius would be a distance, not a velocity.

YAY BERET GUY![[User:Mathmaster|Mathmaster]] ([[User talk:Mathmaster|talk]])

Beret Guy's estimate is, of course, absurd (or it would be for anyone else). His lifting capacity, the breaking points of his line and rod, the buoyancy of his boat and the force to break loose an individual piece of rock (the lowest of which would mark the upper bounds for his estimate) are (many) orders of magnitude lower than the force required to haul a 10^24 kg catch into the boat [citation needed, I guess] [[User:627235|627235]] ([[User talk:627235|talk]]) 11:42, 11 December 2025 (UTC)

:When he pulls, there is a little bit of give (infinitesimal) as the planet moves - he might be sensing that and estimating based on it. Assuming you know the properties of the fishing line, like its stretch, and of the boat's surface area, buoyancy. I don't see why it wouldn't be possible to estimate given perfect knowledge of the water, boat, line, forces, etc, even if the Earth is much more massive than the boat being pulled downwards [[User:R128|R128]] ([[User talk:R128|talk]]) 15:22, 11 December 2025 (UTC)
:At that massive scale, wouldn’t the upper bound of weight he could detect the buoyancy of the boat - beyond that he is no longer pulling anything up, but pulling himself down - so that the resistance he feels is the buoyancy keeping the boat up?

:You have to have a 'feel' for the potential elongation of the line (which depends a bit upon knowing how much you've deployed), the properties of the rod and (at least for fish, which weigh 'nothing', when they wish to be neutrally buoyant, but have a muscle-related resistive power and a degree of swim-bladder 'weight adjustment) the pseudo-weight that a given size of likely catch (of a likely species) fights against your line-tug with. You can get fooled that a static-snag is actively fighting you if you think you're ''only'' dealing with a fairly shallow fish when you've managed to snag onto something somewhat deeper so that the resonance of your attempts to pull give you the feeling of a reaction that's more just some kind of Young's Modulus/Hooke's Law artefact. It all feels completely different from a fish finally wrested entirely out of the water, and even allows a catch that's heavier than the eventual breaking-stress of your line (or weight+its effort to be greater than that) to be gradually played towards you while in the water, tiring it and bringing it into reach of your grasp/catch-net that will do the actual work of landing it.
:Though, in this case, I think that Beret Guy ''knows'' how much line he is using/etc, and that he's hooked a planet (however that feels) rather than a more actively resisting (and tiring) seacreature. But by the ''very subtle'' reaction of the body to 'test tugs' (accounting for how this also moves the boat) he has correctly (within an order of magnitude!) assessed its 'dry mass'.
:(A cynic might ask what ''other'' masses he might have caught, between Earth-sized and the next most massive mass that's hookable in this manner... a large part of the Titanic..? Having established that it 'tugs back' more than the latter, then Earth would be the only logical target to lead to such a 'logical guess' of mass. Though even establishing that it isn't a massive shipwreck probably needs extremely well tuned supersenses to rule out.

::::With the widespread ignoring of such laws, I am of course not surprised that people who may-or-may-not have even passed a driving test (or cycling proficiency test) are riding bikes badly. But I don't have to like it. And (like the title-text's forcing of 'lesser vehicles' off the road), I'd rather not have it rebounding upon those of us who ''aren't'' troublemakers.
::::It ''almost'' wants me to change my mind over the ideas of having "taxed, insured and registration-plated" cycles. But that is what other people suggest, probably to 'restore' the car's supremacy of the road (short-sightedly and ignorant of road-history) by making supposed nuisance-cyclists be made accountable (while they'll be shocked if they're ever stopped from going 30 in a 20-zone, or 90 in a NSL-zone).
::::This is no kneejerk opinion. I've been a cyclist for the best part of five decades (only marginally less than I've been walking, though I was also apparently first taken out in a cycle-trailer as a week-old baby) and a motorist for well over three. I've seen cycling become diminished as an everyday past-time and 'biking' spring up as a more elitish one (MAMILs, etc). And the rise of "Kensington Tractors", in the UK, but luckily it's still not heading inexorably down the comic's story. And if I can do my bit to evangelise for general law-abiding consideration and prick the conscience of ''all'' road users (and pedestrians), without myself causing problems to others (I don't count blocking those who intend to drive faster than my on-the-limit speed, just wait until I'm going slower than that because I don't want to spin off an icy road!), I will do so without apology. It doesn't have to be like that (cycling in Belgium is a dream, better even than the Netherlands, with not too shabby experiences from other countries from Denmark through to France), and really shouldn't be like the US, where even ''walking'' often seems to be an inconvenient eccentricity that's barely tolerated.
::::Ok, more enough of that. Most people reading this will never share the roads with me, anyway, even if you might. And Jeremy Vine has nothing to do with it.

I realize this is US-specific, but the comic completely ignores the fact that vehicle manufacturers are incentivized by the US Government to increase the size of the cars they design, since the CAFE standards are graduated based on vehicle size.

A fundamental problem with this comic is that a "good carpenter" really means "an efficient carpenter" (true of any craftsman, really). Economy of motion, skilled enough to know when to be really precise and to know when precision doesn't matter and is a waste of time. The efficient carpenter doesn't need to measure twice, he or she gets it right on the first try. Or, consistent with the above, knows their capabilities well enough so they can only measure twice when it's truly necessary. And, of course, some of the best efficiencies come from not "measuring" at all — using an end stop or a jig so the cut is easy and repeatable without measurement. Drawing a line (or cutting without a line) against the actual reference point rather than against an intermediate measurement tool (some might call this "scribing," but that suggests a level of precision that isn't what I mean). Effectively, "measure zero times, cut once." And in the opposite, sometimes the most efficient approach is not to measure at all (whether numerically or against a reference object), but to make a rough cut and then a finish cut — effectively, "measure zero times, cut twice." Also possible is if you are gang cutting a stack of N boards, you measure 0 times or once and then make 1 cut, so on a per-board basis it's measure once, cut 1/N. I don't know that all of these things are obvious, per se, but I can't help feel surprised that they don't seem to have been considered.

==Explanation==
{{incomplete|This page was created BY A REALLY BAD METALWORKER. Don't remove this notice too soon.}}

As indicated in the comic, "Measure twice, cut once" is a {{w|proverb}}, which means that planning and checking multiple times before acting is less costly than the mistakes that can follow from not doing so. The metaphor is of marking the place on a piece of material where you plan to cut and then verifying that measurement before cutting, to avoid the later waste involved in either trimming down the cut piece, or starting again with a whole new piece, if it turns out the first measurement was in error. ([[Randall]] claims it as a "carpentry proverb", but in fact it is not clear what it specifically originates in reference to, and it could equally well apply in a literal sense to other activities such as tailoring, leather-working, and so on.)

The comic takes the proverb literally, consisting of a graph of various activities involving measuring and/or cutting, showing the number of cuts made versus measurements (though it does not provide actual values). Starting with the carpenters, these are:

; Good Carpenter
A good carpenter would measure twice and cut once, if following the archetypal proverb.

; Careless Carpenter
A careless carpenter would measure just once, then cut once, not following the proverb. This could lead to simple mistakes that create pieces that don't actually fit, and thus waste wood (and/or time) in order to fix the issues.

; Really Bad Carpenter
A particularly poor carpenter would not always even make an attempt to measure (here indicated by being ''slightly'' lower on the scale than the presumed single-measurement position) and cut twice or more, almost following the proverb in reverse. It also suggests that they may not merely have not measured correctly, but aren't even skilled enough to have tried to apply the correct measurements in the first place. While a careless carpenter might muddle through with the occasional error, it is likely that the really bad one makes even more mistakes and wastes even more wood.

: The remaining classifications are not carpenters at all.

; Surgeon
{{w|Surgery}} is a task requiring a great deal of precision, being on a living creature, not an inanimate object, and therefore having far less room for error. Extensive measurements and diagnoses must be performed prior to making cuts, but cuts are still made. The cuts are minimal (i.e. singular, as far as possible) and must be deliberate and precise. This positions the surgeon at beyond even the Good Carpenter, insofar as pre-cut measurements.

; Surveyor
Surveyors have the task of measuring land. They measure boundaries, elevations, and distances, but are rarely asked to physically cut anything themselves; they only produce measurements and maps, for which they typically would make multiple measurements to ensure accurate and thorough charts for those who will make later use of them.

Surveyors often need to clear trees and bushes from a property line to be able to see or measure from one corner to another. These are called "cuts" in some American jargon.

; Serial Killer
Would not normally require any particular attempted measurement at all, depending upon their particular ''{{w|Modus operandi#Term|modus operandi}}''. But, if this involves knives, multiple victims would necessarily require potentially large amounts of cutting, stabbing, slashing, etc.

; Title text
The title text mentions a carpenter who does zero measuring and zero cutting. This is depicted as the epitome of expertise, because they have apparently achieved a superior {{w|Zen|philosophical enlightenment}} towards their task, perhaps being able to achieve their aim with the materials exactly as already provided by fate, or to adjust their aims to align with the existing reality of the universe.

I would hope that Randall was aware of John Finnemore's radio sitcom "Cabin Pressure", as a very compatible sense of intelligent humour (with the 'u', 'cos British!). Though maybe not ('cos British radio, might be too fringe a taste), and so the fact that one of the episodes has a somewhat similar plotpoint to it (not saying which, and how, as anyone who'd like to start listening might just appreciate not knowing "this is the one where..." before it happens) probably isn't worth fully analysing (with an 's', 'cos British! :p ) in the explanation. But just mentioning it here, in passing, given that it reminds me of it.
 ...also, as well as bridge heights, I hope they have a good idea about carriageway widths, for the undercarriage, and road furniture (like lampposts/roadsigns, and telegraph/powerline poles) ''plus'' structures (buildings, and bridge-spans, and even groundworks like cuttings through an overlying grade) , for the wings. Though maybe a flight(/taxi) between two places in a relatively undeveloped landscape, having just wide surfaced roads and nothing more immediately prominent than relatively sliceable giant saguaro cactii. Which I can imagine (for the sake of the joke) in the US, but would probably rule out absolutely every possible road route here in the Uk, for any aircraft bigger than a microlight.

Maybe I'm misunderstanding, though, since obviously cars are bigger than rollerskates. So perhaps the intention was to comment on trucks and planes being disallowed.

The whole bullet list under "motives and feasibility" seems very out of place, and the sentence preceding it is completely vacuous. I mean, "a number of factors contribute to the dilemma"? Which dilemma? There's no dilemma here, only a joke. And what dilemma does ''not'' have more than one contributing factor? This communicates nothing and just takes up space. The items in the bullet list itself just seem off topic; a comparison between on-plane and off-plane ground transport does not belong in a section titled "motives and feasibility".

==Explanation==
{{incomplete|This page was created by JOLLY ROGER'S HEAT SINK. Don't remove this notice too soon.}}
Heat pumps are used to remove or add heat into a house, normally the air or ground is used as a heat sink, not other people's homes.

Using your neighbor's home as a heat sink would offer energy efficiency saving to you, while adding to your neighbor's energy bill.

:We have long made a distinction between "iron" and "steel", not to mention that, while stainless steel has about 1% carbon by weight (give or take: sometime more, sometimes less), since carbon is over 4 times lighter than iron, that makes about 4% (and up to 10%) of the atoms carbon, not to mention that, to be stainless, it has to either have a by weight composition of either over 10% chromium or over 8% nickel, which are almost the same weight as iron (a difference of around 5%, lower for chromium, higher for nickel). Given that the average stainless steel has a 18% by weight of chromium, adding that with the carbon means that only 3 out of 4 atoms are iron, and if you have copper and tin or copper and tin in that same ratio, it would long have surpassed the line to be called "bronze" or "brass", respectively.

::99% is a way higher percentage than say, the amount of nickel in nickels ($0.05 coins): 25% ({{w|Nickel (United States coin)|US}}) or 2% ({{w|Nickel (Canadian coin)|Canadian}}). The latter might qualify for this list because it actually used to be made of near-pure nickel, while the US coin's composition never changed since the first (1866) version that became known as the "nickel".

Steel (stainless or otherwise) does not occur naturally. It has to be made. By humans. Out of iron. So in this case 'having iron atoms' DOES mean 'made of (as a synonym of 'from') iron'. [[Special:Contributions/172.70.86.129|172.70.86.129]] 04:11, 14 April 2025 (UTC)

"Cutlery" specifically refers to metallic implements with a cutting edge. Knives, scissors, and swords are cutlery; Spoons and forks are not cutlery. Table knives, forks, and spoons, collectively are "flatware". [[Special:Contributions/162.158.164.155|162.158.164.155]] 10:01, 12 April 2025 (UTC)
:I was really hoping to re-edit that element, anyway. The comic says "silverware" which can relate to cutlery/other food-implements or to the plates or candlesticks or even ''trophies''.

[[Special:Contributions/172.70.58.49|172.70.58.49]] 22:58, 12 April 2025 (UTC)

I assume the confusion comes from the respecive British and American terms for a collection of forks, knives, and spoons. British English calls these things "cutlery" even if they don't have a cutting edge. American English commonly refers to these as "silverware," especially when made with stainless steel, although I have also heard the term "plastic silverware" or "wooden silverware" when "flatware" would probably have been a more accurate generic term.

You can even make paper out of old clothes made from vegetable textiles (like blue jeans, cotton T-shirts or hemp pants).

This, this is the hill I will die on. I was radicalised by this paper: [https://arxiv.org/abs/2110.15285 Moons Are Planets: "Scientific Usefulness Versus Cultural Teleology in the Taxonomy of Planetary Science"]
In short; planets are what planetary scientists study. Round things with the *good stuff*: atmospheres, oceans, volcanoes (of lava or water ice) (see diagram page 53).
Pluto, Titan, Ceres, Io and Europa are all in the sweet spot where you're not so small you're just a lump of rocks who happen to be stuck together into a lump, and not so large you're just a mostly undifferentiated mass of fusing hydrogen/helium plasma.
And it's consistent with our pre-20th Century understanding of what a planet is, whereas the IAU definition is trying to preserve 19th Century astrology.

Does anyone else strongly dislike the term '''natural satellite''' replacing ''moon''? Under the new nomenclature, only Earth's moon is 'the Moon'. All other moons are now merely natural satellites.

Using rice paper you could easily reach 9 steps by pure hand pressure, although reaching fusion point -at or around 80 steps- would definitely require strong fingers indeed. Black holes clearly cannot exist, because they would require folding Chinese paper more than a red-blooded American can do, and this is not an option.{{unsigned ip|141.101.68.192|22:13, 3 January 2025}}

The current explanation that it's impossible to create a black hole by folding paper is only right in practical terms.

I would be impressed if you did manage to keep folding, since the goal size can be measured in Planck lengths with only six digits. Would you define it as a 'fold' after the entire thing fits inside an electron? (Tangentially, I'm not sure what theory suggests here - can a black hole exist at a scale which makes quantum tunnelling trivial?) {{unsigned ip|172.68.210.114|23:09, 3 January 2025}}

This strip loosely follows a routine by Emo Philips in the 1980's where he describes tearing a piece of paper in half repeatedly until it explodes. He didn't give a count though. [[Special:Contributions/172.71.154.140|172.71.154.140]] 01:22, 4 January 2025 (UTC)

So, based on some quick math:
If we take the 10^110 meters of paper needed to complete this many folds, then you definitely can easily make a black hole. Generously assuming a 1mm wide strip, this gives us a folded stack of paper 1mm wide, 10^53 meters tall and long. 1 light year is 10^15 meters. So this piece of paper is now 10^38 light years long and wide. I.e. something like 10^27 universes tall and long.

Using the 70g per square meter number used above, you get 7^105 kg total mass. One solar mass is roughly 2^30 kg. Our paper weighs something like 10^54 times as much as the observable universe. This is very likely enough to reverse the expansion of the universe, and cause the entire observable universe to turn into a black hole. Or would it be a new big bang? I wonder what theoretical physics would say about a universe with 10^54 times as much mass / energy.

Also how exact does this comment system work? Is it easier if I just make an account?

If someone wants to describe the logo on the Neutrino Modem in the transcript, have at it. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 22:42, 27 November 2024 (UTC)

I wonder how long it took Cueball to send and receive enough packets to be able to calculate that average ping time? [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 22:47, 27 November 2024 (UTC)

If you ping every IPv4 address on the planet once a second, 3-4 packets will be received per day. Unfortunately, the packet loss is bidirectional, so your chance of hearing the reply is equally low. So maybe when the earth is 16 times older than it is now you will have a reply. [[User:Divad27182|Divad27182]] ([[User talk:Divad27182|talk]]) 23:13, 27 November 2024 (UTC)

That packet loss rate (detecting only 1 in 100 trillion) is actually a very high rate of neutrino detection, isn't it? And that's assuming a "packet" is a single neutrino. [[User:DKMell|DKMell]] ([[User talk:DKMell|talk]]) 23:33, 27 November 2024 (UTC)
:Ah, yes, just added something about that. Going by (confirmable) solar-neutrino detection rates, because I couldn't work with figures for generated/detected neutrino streams (and, besides, you might then have {{w|2011 OPERA faster-than-light neutrino anomaly|FTL latency times!}} :D ), it seemed that we're detecting hundreds of events ''per day'' in "cubic kilometre" detectors which would be being hit by perhaps 60-65 million neutrinos ''per second per square centimetre'' so I don't think it's far wrong (scaling up to the square face of the cube, over a full day) to suggest one in 50 long-Trillion (or 50 short-sextillion) neutrinos is identifiably captured. The rates might be better for merely "several olympic swimming pools of fluid" detectors, so I fudged it rather than talk of 1018ish rates with respect to the 1014ish ones quoted. (Which, because it is at least ''two'' neutrinos, one there and one back (with magically implied Ping Request/Ping Response status), is more like two 107ish rates anyway, in order that the neutrino-spamming is equally intense from either side in order to attempt to minimally convey a message... Could still be short-trillions sent, one ping request detected, short-trillions replied to that one as a similar 'overkill', yet one valid returnee received.)
:But if I'm overestimating (or underusing, on the flipside) anything by an order of magnitude or three, then it still doesn't really change the comparison. The numbers are still huge. We don't even know the transmission bandwidth, just that somehow Ping-Request then Ping-Reply (and no other ACKing and handshaking or OSI Physical Layer overheads, never mind other layer 2, 3 and 4 fine details) happened at practically the speed of light regardless of the necessary near-simultaneous spamming of attempts that the boxes that each endpoint concerned must have to juggle when prodded accordingly.

3005: Disposal

2024-11-04T13:29:07Z

SDSpivey:

{{comic
| number = 3005
| date = October 30, 2024
| title = Disposal
| image = disposal_2x.png
| imagesize = 740x331px
| noexpand = true
| titletext = We were disappointed that the rocket didn't make a THOOOONK noise when it went into the tube, but we're setting up big loudspeakers for future launches to add the sound effect.
}}

==Explanation==
{{incomplete|Created by a MINESHAFT-TARGETING ROCKET - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This comic came out a couple of weeks after the successful first attempt to 'catch' a rocket during {{w|Starship flight test 5}}, based upon {{w|SpaceX}} having {{w|Falcon 9 first-stage landing tests|an extensive history}} of bringing rocket stages back to Earth in a controlled manner. Whereas the traditional approach was for such rocketry to allow most of the initial launch-vehicle to be a single-use stage that was effectively destroyed once it had fulfiled its purpose, it has become a developmental aim across much of the commercial side of the industry to introduce as much reusability as possible in the mission hardware to potentially save costs and construction time.

In order to accomplish a successful recovery, expended stages have been given unprecedented ability to control their fall back to the ground, often in a manner that allows them to propulsively halt their descent directly over a prepared landing pad (on land or sea) and settle down softly enough on landing gear to be refurbished and reused (sometimes for {{w|List of Falcon 9 first-stage boosters#Booster 1061|more than twenty subsequent missions}}). For the recent Starship test, the one (and, as of this comic, only) attempt to recover its {{w|SpaceX Super Heavy#B9%E2%80%93B12|Super Heavy Booster}} involved being precisely guided to be ''caught'' by the {{w|SpaceX Starbase#Orbital Launch Pad A|original launch tower}}; though it is never expected to refly, as a test prototype, it survived the whole process. This is in contrast with [https://www.youtube.com/watch?v=bvim4rsNHkQ plenty of examples], where the landings (or their aftermath) were not quite so successful.

Though SpaceX is the current leader in such an accomplishments, there are other companies who are various degrees along a similar developmental route. [[Randall]] claims that he has an organisation that is amongst them, and has achieved the non-trivial feat of being able to direct the discarded rocket stage ''very precisely'', yet without that extra bit of ability to ensure that it doesn’t then subsequently explode. The team has therefore decided to exploit their achievement (to precisely control the rocket) to send it 'safely' into a hole that (barely larger than the rocket's cross-section, and with a sturdy lid directly manhandled by a [[Cueball]] employee) allows it to {{wiktionary|rapid unplanned disassembly|rapidly disassemble}} in a planned and 'safe' manner. Of course, as a [[:Category:Compromise|'compromise']], it does not achieve the original aims of recoverability and reusability, yet it also is intrinsically far more complicated than the default option of just letting the hardware generally fall to destruction somewhere in a handy 'empty' down-range area that {{w|Spacecraft cemetery|shouldn't inconvenience anybody}}.

With the comic depicting the 'disposed' stage as powering downwards, this might explain their lack of success in perfecting any form of intact recovery, as practical examples of this technology tend to spin the craft around to make use of the main thruster(s) for a {{w|retrorocket}}-assisted {{w|VTOL|landing}}, or at least don't try to counteract the passive deceleration provided by parachutes or other purposeful aerodynamic drag, in order to touch the ground at a survivable velocity.

An explosion in a sealed container is potentially much more dangerous than an explosion in the open, depending on the strength of the container. If the container is strong enough to hold the pressure from the explosion, that pressure could be released in a controlled fashion, safely. But if the container is too weak, it could suffer a catastrophic failure, sending shards of its walls and anything around it flying outwards at high speed. Even if the container is initially strong enough, it could be weakened by repeated explosions, and fail at a random time in the future. As the 'container' is mostly a hole dug into the ground, of indeterminate depth, it might be considered fairly robust in itself, especially if given a reinforced lining. However, this then risks forcing the majority of the resulting explosion up into the lid, which looks strong and heavy yet is closed at least partly by the effort of just one person. It also risks that worker being right next to the track of the descending rocket stage, where they would be at risk of experiencing all kinds of secondary damage, if not being directly in the explosion if they get the timing of the lid-closure wrong. An actual {{w|Operation_Plumbbob#Missing_steel_bore_cap|attempt to put a lid on an underground explosion}} succeeded only in blowing the lid off at such velocity that it was never found.

The title seems to refer to the sound effects of dragging an element into the trash on computers. Or, alternatively, the sound of a canister being sucked into a vacuum tube. This is likely a reference to Tesla vehicles being quiet and having "vroom" noises pumped into the cabin to satisfy customers.

I understand that Watership Down is sometimes categorized as "children's literature", but it always catches me off guard.

From the perspective of someone who lived through the 1980s Miner's Strike (not directly affected, my father worked at a steel-works, not at a pit like my friends' fathers) and then the decline of the steel manufacturing industry (which ''did'' affect my father, obviously), I have rather naturally kept a general eye on the extraction and use of coal. There still are working coal-mines (though there isn't going to be that new one, in Cumbria), and there are still uses for UK coal (enough to import to add to tht which we dig out). It's really a bit early to say that the layer of total coal dug out ''won't'' deepen slightly (very, very slightly) in the future. And coal that is dug is only loosely associated with coal which is turned into electricity, so the last coal-generator stopping seems like an oddly off-topic detail for Randall to leap into the amortised accumulation of extracted volume.

Yes, the other things, by skipping the 'bad end' they actually had, would still be susceptible to future incidents (lessons not now having been properly learnt, or even known to be learnable, so still liable to being mishandled).
:But the only thing that could have saved the Tacoma bridge was to have been so much more alert (and less 'amused') by Galloping Gerti and immediately rushed into developing the better analytical models that could lead to an expensive in-situ retrofit (as with the Millenium Bridge, across the Thames, though that didn't have unavoidable wind issues and ''could'' be managed 'at leisure', whilst being made safer). And, without the rather spectacular demonstration of failure, it was probably not on the cards to 'not do nothing', even if it wasn't already too late to avert history in any reasonable way.
:It's human hubris/failings (at various levels) in each case, of course. But operational and design-time errors do more damage in combination than either by themselves.

The room code 020518 as listed consists of prime numbers 2 and 5 (with 3 missing). however both are preceded by a zero. The 18 is interpreted as non prime (it is not) but the 2x3x3 seems a bit far off from any prime. Would the alternative explanation 0-5 is a zero followed by the prime number five --- followed by 1 - 8 which is 0+1 and 7+1 which could be logical continuation of 0+0-5+0, 0+1-7+1, followed by e.g. 0+2, 11+2 etc. - as such series sometime go.

:: As a pedestrian (amongst my other road-uses), I occasionally have to cross a two-lane carriageway (to the median, then across the opposite two-lane carriageway) near a junction (roundabout, in the UK; and the first lane dedicated to turning in (left, equiv. to a US right-turn) to the side-road) and the initial lane is often either entirely empty or jammed up by those trying to turn into the retail park that sits there. I have to juggle the kindness of drivers who will slow (or stay stopped) to let me across their lane with the possibility of having other (faster-moving) traffic still coming up on the other lane. It's possible to use the twixt-lane white line as a kind of unofficial demi-median (the stopped driver will not forget that they let you go there), but I'd rather not surprise the through-traffic lane by giving them an alarming glimpse of a pedestrian maybe about to step out in front of them, so I might try to indicate to the kind driver (with friendly gestures) that I'm observing someone coming up on their offside (due to slight bend, on entry to the junction, they might not see them in their own offside mirror), perhaps even then stand back and wave them past because ''I'' can see a glut of offside traffic, from my head-height position. Or just avoid those times of the day when there's heavy shopping/commuting traffic causing that sort of problem.
:: (Yes, it ''is'' a proper crossing point. Dropped kerbs for those that need dropped kerbs, though not given pelican/zebra/etc explicit crossing markings and signage. An alternate way 'across' is a walk down to a canal that the onward road crosses by bridge, under that bridge on the tow-path and then back to meet the opposite side of the road.)
:: The junction-exit carriageway is far simpler. You can see when traffic is coming down the through-road ''or'' spinning round the island from the RP exit (or U-turning from the first carriageway!) and either there's a third-of-a-mile queue backed up from the next junction or there's no traffic impeding those going that way to leave me with space to cross.
:: The opposite crossing is a matter of the 'easy' junction-exit carriageway (as just given) plus an unrestricted view of the fast-lane, but then you need to catch the eye of any queued turn-lane vehicles (and look at what round-the-roundabout traffic might be holding the front of that queue up, in the near future) to make sure that when you take advantage of a clear offside then the subsequent nearside cars don't start shuffling up. And recognise the oblivious/inconsiderate/obtuse drivers by their general road positioning and attitude at the wheel. (It's a bit of an art, but stood me in good stead so far.)
:: There is also, elsewher, a ''particularly'' akward right-turn (UK, remember) onto a mainish road, that I sometimes need to drive round. It comes in as single-becoming-double lane, but these days that double is buslane and singular other (from the right, the double-becoming-single is also buslane nearside, except for inward turners who aren't in contention with me but ''are'' potentially view-blocking). Between the two carriageways (which merge, at the single-lane side, as two standard single contra-carriageways beyond an actual light-controlled staggered pedestrian crossing) is the central turning refuge that I potentially need to pause in to turn right, and left-approaching traffic may need to pause in (crossing my path) to turn into the road I'm emerging from. The most problematic are the turning-in cars that ''don't signal'' (or far too late), given that everyone (not a bus) has to keep right anyway on this widened stretch, but some of them are keeping right in order to turn right. And driver-to-driver visual communication (or even seeing if they're glancing in your direction/meeting your questioning gaze) is isn't helped by angled windscreens often drowning out (apparent) driver-on-driver visibility by the reflection of the sky above. So it pays to be cautious, and taking a moment before taking apparent cues (arm waves, light flashes, etc) as you think they might be intended.

:Transitions lenses are misplaced. The only caveat is that if you like outdoor photography (landscapes, wildlife, etc.) you should get grey lenses rather than brown ones, because the brown ones make a blue sky seem overcast. [[User:Pjt33|Pjt33]] ([[User talk:Pjt33|talk]]) 09:22, 7 May 2024 (UTC)
::The precise opposite is true. Grey lenses make ''all'' things - blue sky included - look greyer, as is perhaps unsurprising. Brown tints involve a degree of orange, which means the overall impression is of a "warmer" colour pallette, rather than simply a duller one. There is a reason that "grey skies" and "overcast" mean ''exactly'' the same thing - an overcast sky ''is'' a grey tinted filter. [[User:Yorkshire Pudding|Yorkshire Pudding]] ([[User talk:Yorkshire Pudding|talk]]) 09:48, 7 May 2024 (UTC)
:::But perceived colour isn't the same as the actual colour hitting the retina: the brain corrects it. A blue sky filtered through a grey lens is still perceived as blue, but I find that a blue sky filtered through a brown lens appears grey. This is from personal experience: I switched from grey Transitions to brown ones because the frame that I liked was a brassy colour, and I regretted it when I next went out for bird photography.

:I think the Transition lens issue is primarily that the bright light that can turn them dark need not be heading into the eye. With the Sun (say) off at an angle, it could be 'reacting' your lenses to dark needlesly, and reducing your ability to discern the things in front of you (which may be in shadow), working against the basic ability of the eye to adjust itself as per observed illumination.
:Conversely, a small bright light would not sufficiently darken the lenses but be still damaging to the spot(s) it falls upon in your retina (or do the "whole lens go dark" thing and ''still'' be too bright even as you can't see anything else beyond it). This might also be combined with the general secondary problem of potentially all regular sunglasses/goggles, that aren't industrial-grade or specific solar-specs, in that it might make it ''look'' safe to stare at bright things/skies through them but you cannot tell how much UV/etc is also being filtered out (some brands do have notable UV protection, but you really have to trust their claims/certifications – unless you have your own testing kit and knowledge of how much is good/bad anyway).
:I'd add that, but it needs a sharper explanation than I just gave.

Leaded gasoline isn't to reduce *noise*. The noise is a symptom of detonation (aka knock), which is the real problem. Knock is caused by pressures and temperatures high enough and for long enough to detonate the fuel/air mixture (as opposed to the deflagration initiated by the spark plug at a set time), and can result in engine damage. Leaded gasoline (through complicated chemistry) increases the pressure/temperature required to get that detonation, and thus allows the engine to be designed to run at higher temperatures and compression ratios, which is where the efficiency improvements come from.

Maybe, cross-reference "Sliced bread" to [[1065:_Shoes]] and [[1885:_Ensemble_Model]] (with sliced bread in both comic and title-text).

I think that the phrase "best thing since a sliced bread" refers to sliced bread in general (as opposed to eating the bread directly or tearing pieces of it) and not specifically bread pre-sliced before buying.

Also, heat pumps, whole not DESIGNED to heat by itself, actually have a limit for how big difference in temperature they can operate in. Outside this limit, they work quite badly and only by heating by itself.

Added my interpretation that this is never going to be "OLCCo presents: the Treasure Hunt!". If everyone realises that the prankster(s) who set all this up had caused their troubles (forcing them to get lawn-care, or do more of it than they already would have done), then OLCCo itself would have problems. Actual customers would leave, potential customers would seek other contractors, many of these would consider going to the courts to claw back costs, other current lawn-carers would absorb all the created work, and further potential lawn-carers might even start offering their services, all off the back of the back-firing campaign. ...

:Looks to me like it's about 2/3 the way between 10^-2 and 10^-1. So call it between 10^-1.3 and 10^-1.4. Which is between 4cm and 5cm. Still a rather large grape, but perhaps more plausible if he's measuring across its widest dimension. 10^-1.6 (2.5cm) would perhaps give a more representative grape length, or maybe 10^-1.7 (2cm) if he normalised the measurements to account for their spheroid(ish) nature. But we'd also have to get in to the question of when is a grape a grape? There will be lots of grapes that will never reach more than a few mm, but not ones that we would normally eat.

:: US and UK/Commonwealth "statute miles" are 1609.344 metres (exactly, since 1959). Though based upon shared origin of 5280 (English) feet. That's probably as International as you can get. (5280*610nm is 3.2208mm of difference if you get mixed up.) But it took a while to even get to "roughly that exact".
:: The Roman Mile was 5000 (Roman) feet, approx 1480m, but led also to the Italian Mile of 1852m-ish by various convolutions, whilst the Chinese 'Mile' is officially 500m. Even within Britain, the Scots Mile was 1807m-ish (as seen between some historic roadside mileposts) and the Welsh version was once around 6,170m (even more historic/obsolete).
:: Even nautical miles are 'wrong' against what they should be, but are nonetheless standardised to their own separate international standard. (You could say "they're in a league of their own", but then ''leagues'' can be anything from 2.2km to 6.6km, at least, depending on where/when you are!)

There are (or used to be) states that specify U.S. survey measure for various things. Others that specify the international definition. Still others that just leave it undefined. Seems normal.

Although it IS a small difference, the survey grid in the U.S. and thus the property lines for a large portion of the U.S. are done with the older definition and a few reference longi- and latitudes. That could make property lines suddenly shift, so the U.S. survey foot may never fully die. I even made sure it's in my app accurately.

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.

Also it is nice for socializing, it is (quite light) exercise, and good for businesses, as you can actually "window-shop" and see what they have as you walk past and spontaniously walk into any store/restaurant/business. --[[User:Lupo|Lupo]] ([[User talk:Lupo|talk]]) 06:24, 25 September 2023 (UTC)

I would be very interested in having a discussion based on the "livability" comment. If a city is a place to LIVE, then these are fair comments, assuming that travel outside the local area is minimal. But if a city is a place to WORK, like a lot of downtown areas in the Eastern US, then this doesn't hold up as well. People don't live in these areas, they just travel to them on a regular basis.
:Talk about missing the forest for the trees
:Agree, downtown areas SHOULD be places to work, live, shop, and play. Eastern US downtowns USED to be that way, until White Flight screwed everything up and created "car culture".

: One thing that always bugs me about these discussions is that they tend to be so city-centric in thinking. Bikes simply aren't a practical mode of transportation in a lot of areas, dating back to pre-car days. I live in a rural area of the southern midwest, and "town" is a concentration of places that people in the area go to, and always has been. Only really wealthy people had houses in town, and even then they were often "Sunday Houses" where you would stay during your weekend trip to town for groceries and church BECAUSE it was such a hassle before cars. There's a "historic" (read: tourist-friendly) walkable town square in the center of many towns in my area, but these are as a rule businesses, some of which have loft apartments because the owner lived there too as some of the town's few constant residents. Even the parking lots are basically paved versions of the spaces where people would park their wagons and tie their horses back in the day, placed near things like general stores because hauling groceries for several blocks is a pain in any era.

Yes, cities are much better place to live in without so many cars. But on the other hand, vacation without car is much more complicated, unless your idea of vacation is to get to exactly same place as everyone else. Soo ... where will all those cars go? I know, you could rent a car, but that only works if there wouldn't be times where EVERYONE suddenly needs car ... like, say, Christmas.

Also, no, bikes are not alternative to cars unless you can get shower when you arrive at work. Public transport could work, but bikes are just nice theory.

: Bikes are an incredibly helpful and useful tool for getting around. You don't even have to turn a city into Amsterdam. I live in Edmonton, which is by no means an urbanist utopia, and even getting around here, combining a bicycle with public transit makes it so much easier and faster to get around. The issue I face is lugging my bike with me, in which case a bike share service like Montréal's BIXI would help out for getting around.
: Regarding your point on vacation, first of all, most people end up going to the same places for vacation anyway. And vacation without bringing a car can very much be done, and even at high-demand times, the places where "everyone needs a car" are places where everyone will be going anyway, at which point a train just makes more sense. About a decade ago, my family took a trip from New Delhi to Goa a decade back (around 1800 km away) and we took trains to get there. We rented a car to get around in Goa and it worked pretty well. Not saying that cars aren't useful at all, but they aren't a 100% necessity. They're most useful when you're heading somewhere that's out of the way, and I've done those sorts of trips too.

"...by allowing cyclists to cycle in the streets with the cars". ''Allowing''? Sorry, but that's a very neo-biker (or "person on a bike", rather than an actual cyclist) attitude that unfortunately seems to pervade the mindset of drivers. At least in the UK, bicycles have been 'allowed' (indeed, obliged) to ride upon the roads, as of laws as far back as [http://www.legislation.gov.uk/ukpga/Will4/5-6/50/section/72 1885] and are legitimate road vehicles and also not supposed to be ridden on actual pavements(/sidewalks) where not explicitly allowed. Of course, the US has policies driven (c.f. jaywalking). But a bicycle is a road vehicle. Add extra permissive routes (in the same manner as allowing traffic of less than three tonnes over a bridge, without forcing everything within that limit to do so) but you'd be wrong to suggest, over here, that you'd have to ''allow'' cyclists to cycle in(/on) the streets. Though the modern 'MAMILs' are often as wrong about all this (and as damaging to the reputation of real cyclists) as far too many motorists are. Of course, this may not reflect the US situation (or state/township legislations), but then they were influenced by the car-lobby to create the jaywalking 'crime' as well, so I really wouldn't be surprised.

I went to the Netherlands on vacation last month and I strongly identify with the guy waving flags and yelling "Netherlands! Netherlands! Netherlands!" in this comic. I was in Rotterdam, not Amsterdam, but I also spent a day in Enschede (near the border with Germany), and the sight was the same: bicycles everywhere, to a degree that would seem absurd anywhere else. I don't think it can be properly expressed in words; one look at the bicycle parking in Rotterdam Central Station and I was in awe that _so many bicycles_ could exist in one place. I used a bicycle to explore from The Haag to Neetle Jans and everywhere I went it was the same story; it isn't just Amsterdam, the entire country is built with bicycles as a solid and safe transportation option. --Faultline 11:32, 24 September 2023 (UTC)

Speaking from the perspective of the UK, Cyclists (and I speak as one, with six decades of experience) are a complex issue. Being road vehicles (and requiring continuous at-grade surfaces, or at least smoothly transitioning slopes, whilst mounted) they need special consideration when laying out where they can go, outwith the baseline highway planning situation. And they also pose difficulties if improperly ridden in pedestrian areas, even if this is somehow due to being 'forced'(/’invited') off the roads by motorists and/or town planners that are in turn posing difficulties to them (legislatively, physically or just psychologically). In an ideal world, there would be no need for cycle lanes (on road), let alone cycle paths (split or shared pavement/sidewalk). And as it is not possible to have cycle-segregation everywhere (ignoring the question of whether forced segregation is a good policy!), I feel that attempting to take bicycles (or indeed other types of cycle!) off the road where it is easy and/or virtue-signalling makes the roads worse for cyclists ''everywhere else''. (And also the pavements worse for pedestrians, everywhere else!) 
There are (according to a quick check) 262,300 miles of paved road in the UK. Apart from the motorways (2,300 miles) and a smattering of other "no cycling" roads (often "motorway standard link roads" or major bridges), all of these are viable cycling routes. Maybe you'd not feel safe on some other routes (mostly a problem stemming from motorists, not the highways), so call it a cool quarter of a million miles. Compare with (again, a quick and unconfirmed check) the apparently 5,220 miles of traffic-free cycle paths (some 'cross country', bridleways/ex-railway/etc, others directly parallel to 'bike unfriendly/hostile/illegal' roadways) and 7,519 miles of on-road cycle lanes (paint and/or bollard-segregated, and I assume this includes bike+bus+taxi lanes and variations on that theme). Clearly, most places that you might want to cycle are not anywhere near covered by a convenient cycle-only(/dominant) path/road/lane/whatever. Even accounting for population density bias (a path-equipped city-centre ''can'' perhaps have a good few hundred thousand cyclists commuting along its copious off-street routes, whereas some remote area of equivalent road-length doesn't have more than a dozen people cycling around/through its country lanes on any given day), there's a distinct gap. 
And the problem is that car drivers (myself also being one, though only ''four'' decades behind the wheel, so what would I know?) seem to start to not anticipate bicycles on the road (or horses, or tractors, or anyone also driving but not actually going at-or-above the posted speed limit, etc) and at best they are startled/annoyed when they encounter their fellow road-users in different contexts. At worst, they 'come into contention' in a rather nasty way for at least one of the parties involved. 
'People on bikes' don't help when they (whether drivers themselves or not) do not obey [https://www.gov.uk/guidance/the-highway-code/rules-for-cyclists-59-to-82 the rules of the road], and/or footway. They give actual cyclists a bad name, make motorists less tolerant of those who actually are folling both the rights and responsibilities of cycle traffic and cause 'contention' with pedestrians on ''their'' supposedly safer routes (and road crossings), amongst other issues. The number of times I've seen someone progress rapidly down a pavement on two wheels, having to swerve round people, swerve to cross side-roads (to use the disabled-friendly drop-curbs), hop onto the road and back on again because of obstructions (curb-mounted parked cars/construction works) and all disrupting (or even causing danger to everyone else off/on the road)... Quite often, they would have been quicker ''and safer'' to have just ridden on the road ''with'' the traffic (without earphones in, they'd also be much more aware so could overtake the slower traffic legally and in full consideration). 
Even worse, when there's a 'pavement biker' riding alongside a road ''with a clearly marked cycle lane'' on it. Road space reserved, but they're endangering pedestrians (and potentially themselves) needlessly. But, adding in the reckless pedestrians who do ''their'' dangerous things (walking up the central reservation of a dual-carriageway, e.g.), it just goes to show that there are unthinking individuals using every form of locomotion and travel (I could moan about thoughtless bus/train passengers, too, and don't get me started on illegal eScooters, motorbikes that may skirt the rules to some extent and possibly soms illegal variations of eBike as well). But, insofar as cycling, I'm not convinced that (partially) changing the road system to mitigate for bad drivers is really the best solution. It barely scratches that surface, it gets abused/ignored by those it may be intended for, it makes those it isn't intended for more resentful/inconsiderate as a push-back and the only obvious and tangible metric is in the press release that "Trumpton Town Council has been able to add five more miles of cyclepath..." (which probably consists of several short stretches of red tarmac is frequently intruded upon by pre-existing highway signage/lamp-posts and frequent "Cyclists Dismount" advisories, running alongside a perfectly ridable road just so long as they filled the wheel-/suspension-damaging potholes and swept the gutters once in a while). 
Can you tell that I've often thought about all these issues? I could go on, or into more detail, but I reckon I've already written far too much, uninvited. [[Special:Contributions/172.70.85.218|172.70.85.218]] 11:48, 24 September 2023 (UTC)

The summation of the situation: 
UNSPECIFIED line + SHORT distance = bicycle, walking, etc. 
SPECIFIED line + SHORT distance = tram, everything in unspecified. 
SPECIFIED line + LONG distance = train. 
UNSPECIFIED line + LONG distance = automobile.
 
The '''most''' important combinations for urban planning are unspecified short and specified long which autos aren't good at.

:In answer the the editor who asked the question in the Edit Summary, about what "SPECIFIED and UNSPECIFIED" mean: Purely from context, I believe "line" above means "route". Some routes are (or can be) established as consistently demanded (for commuting, shopping, between major hubs half a continent away, etc) and can be "specified" as schedulable service for mass transit/infrastructure (anything from viable greyhound route with suitable identifiable service stops to an airline route (requiring airports at each end) or something asking for a railway/hyperloop/road to be either maintained (because it already exists) or created (because it does not at the moment) and is worth the while for such a special consideration. There's a degree of predictability to it, because of a mix of the same people regularly needing to make the trip (e.g. commute) and/or a continual/periodic demand by new people to make that journey (e.g. touristic purposes).
:An 'unspecified' route, here, would then be anything ad-hoc, at a frequency or quantity of use well below any particular reason to uphold a service or infrastructure (or coordinated compound of such facilities, like a shuttle bus to and from the station/airport to collect those flying in from afar), and would be served by such private efforts across and through whatever generic routable methodologies exist to be be exploited.
:And each of those two distinctions is multiplied by (at least!) two separate distinctions, that of length. (I'd be tempted to further split into other distances. Maybe localised, district, intra-state (from a US perspective), national and international, but that'd depend on what groupings I was analusing, and obviously a train could take one from one end of a (large enough) neighbourhood to the other ''or'' across the country (with the right conenctivity, even into another one!), depending upon which train and where it stops.

They give actual cyclists a bad name, make motorists less tolerant of those who actually are folling both the rights and responsibilities of cycle traffic and cause 'contention' with pedestrians on ''their'' supposedly safer routes (and road crossings), amongst other issues. The number of times I've seen someone progress rapidly down a pavement on two wheels, having to swerve round people, swerve to cross side-roads (to use the disabled-friendly drop-curbs), hop onto the road and back on again because of obstructions (curb-mounted parked cars/construction works) and all disrupting (or even causing danger to everyone else off/on the road)... Quite often, they would have been quicker ''and safer'' to have just ridden on the road ''with'' the traffic (without earphones in, they'd also be much more aware so could overtake the slower traffic legally and in full consideration). 
Even worse, when there's a 'pavement biker' riding alongside a road ''with a clearly marked cycle lane'' on it. Road space reserved, but they're endangering pedestrians (and potentially themselves) needlessly. But, adding in the reckless pedestrians who do ''their'' dangerous things (walking up the central reservation of a dual-carriageway, e.g.), it just goes to show that there are unthinking individuals using every form of locomotion and travel (I could moan about thoughtless bus/train passengers, too, and don't get me started on illegal eScooters, motorbikes that may skirt the rules to some extent and possibly soms illegal variations of eBike as well). But, insofar as cycling, I'm not convinced that (partially) changing the road system to mitigate for bad drivers is really the best solution. It barely scratches that surface, it gets abused/ignored by those it may be intended for, it makes those it isn't intended for more resentful/inconsiderate as a push-back and the only obvious and tangible metric is in the press release that "Trumpton Town Council has been able to add five more miles of cyclepath..." (which probably consists of several short stretches of red tarmac is frequently intruded upon by pre-existing highway signage/lamp-posts and frequent "Cyclists Dismount" advisories, running alongside a perfectly ridable road just so long as they filled the wheel-/suspension-damaging potholes and swept the gutters once in a while). 
Can you tell that I've often thought about all these issues? I could go on, or into more detail, but I reckon I've already written far too much, uninvited. [[Special:Contributions/172.70.85.218|172.70.85.218]] 11:48, 24 September 2023 (UTC)

The summation of the situation:
UNSPECIFIED line + SHORT distance = bicycle, walking, etc.
SPECIFIED line + SHORT distance = tram, everything in unspecified.
SPECIFIED line + LONG distance = train.
UNSPECIFIED line + LONG distance = automobile.

The '''most''' important combinations for urban planning are unspecified short and specified long which autos aren't good at. The one autos are good at is the least important.

Why do people have to add "Citation Needed" tags when there is no need, nor is it funny. The joke stopped being funny at least a decade ago. [[User:SDSpivey|SDSpivey]] ([[User talk:SDSpivey|talk]]) 16:21, 9 September 2023 (UTC)

:I can give you a very quick summary: when startled, vultures will sometimes regurgitate their last meal, both to lighten themselves for a quick escape, and make a potential predator lose its appetite. Apparently, something startled a bunch of vultures at the same time, and nobody knows exactly what. [[Special:Contributions/172.69.247.42|172.69.247.42]] 14:55, 11 August 2023 (UTC)

On August 11, 2023, XKCD was not the only web comic to reference the "Kentucky Meat Shower". It is the full subject of the day's Dinosaur Comics, at http://www.qwantz.com/index.php?comic=4085. And August 11 is not even an anniversary of the event (March 3, 1876). Coincidence? Time travel? You be the judge. [[User:JohnB|JohnB]] ([[User talk:JohnB|talk]]) 15:32, 11 August 2023 (UTC)

This tells me neither how acceptable things like my default lazy pronunciation, nor the original ancient greek pronunciation of its namesake, are considered. How am I supposed to guess where combinations of variations like PEER-, -seh-, and -ides would affect placement in the list?

*PER-see-ids: standard(ish, YMMV) 3-syllable verson of the word.
*PURSE-yids: standardish 2-(/2.5-)syllable version.
*Per-SEE-ids: yeah, I'd accept that emphisis, in a pinch.
*Per-SAY-ids: ok, so you like ''that'' version of the 'ei' digraph; might even be 'classical'.
*Per-SIDES: Germanic digraph and irregular (in this case) phomeme boundries, but each to their own.
*Per-ZAY-uds: I can see most of this, accent permitting; the '<schwa>ds' is a surprising twist.
*PER-suds: you dont care about the digraph at all, do you?
*Perky-ids: Back-formed through "C/S equivalence", I'm guessing, but from the wrong s(e)ide?
*Pewpewpews: Onomatopœia!!!
*Per-say-say: Bowdlerised, as if the original is a 'naughty' word.
*Percies: Shortened through familiarity.
*Purps: Shortened/perhaps linked to "perp(etrator)s".
*Pepsids: Sponsorship! (Did we also get the "Dracokids", 6-10 Oct?)
*Peeps: Anthopomorphised, the lot of 'em!
...my first thoughts, but I'm sure there are competing claims so I'll leave this down here for the time being. [[Special:Contributions/162.158.74.47|162.158.74.47]] 23:28, 11 August 2023 (UTC)

The list in the Explanation's table was missing most of them, and the Transcript separated the two-word entries into separate entries! Fixed all that. Filled in my analyses of the missing pronunciations, I'm sure others can flesh them out better, add relevant links as I couldn't be bothered to both think of th8ngs to link and figure out the best way to link them (and make the multi-entry rows look proper). Also, someone severely misunderstood what "Peeps" would mean, it seems clearly to be the slang for "people". The goofy entries seemed to require separate descriptions, so I left them as separate rows as the cleanest/clearest layout I can think of for that, with the rudimentary understanding of Wiki tables I could glean from what was already there. :) [[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 06:46, 12 August 2023 (UTC)

I think the "Pepsids Peeps" is a reference to the Pepsi x Peeps soda that got released a few months ago—the first word could be a cross between PEPSI and perseiDS. Presumably, they are very sugary meteors. [[Special:Contributions/172.68.150.46|172.68.150.46]] 12:00, 12 August 2023 (UTC)
