==Explanation==
{{incomplete|Created by an EXPONENTIAL TEMPERATURE SYSTEM. Do NOT delete this tag too soon.}}

Since the invention of the thermometer, a number of different temperature scales have been proposed. In modern times, most of the world uses {{w|Celsius}} for everyday temperature measurements, as it is part of the {{w|metric system}} that has been widely adopted for official uses. A small number of countries (namely Liberia, the USA and its three associated free states in the Pacific) retain the US customary (or 'imperial') system, which uses the ''slightly'' older {{w|Fahrenheit}} scale (°F was initially proposed in 1724, and refined in later years; °C, more or less as we currently know it, was established in 1743). The other widely used temperature scale is {{w|kelvin}}, which uses the same scale as Celsius, but is rooted at {{w|absolute zero}}, making it both useful in scientific calculations and easy to convert to and from Celsius (which, along with Fahrenheit, is now officially defined directly against the kelvin). Even in countries that use Fahrenheit regularly, scientific measurements are typically done in Celsius and/or kelvin.

The strip proceeds to compare these scales, and a number of others, on a scaled of "cursedness." The joke is highlighting how different the proposed temperature scales are. All of the listed scales are real, but may be considered obsolete to varying degrees. See also [[1923: Felsius]], a combination of Fahrenheit and Celsius.

! scope="col" | Explanation
|-
| {{w|Celsius}} || 0 || 100 || Used in most of the world || 2/10 || Celsius (°C) is defined (now indirectly, by comparison to the kelvin scale) so that the freezing and boiling points of pure water at standard atmospheric pressure are set at 0°C and 100°C, respectively. It is regarded as one of the least problematic temperature systems, along with kelvin, among those that are commonly ranked.
|-
| {{w|Kelvin}} || 273.15 || 373.15 || 0K is absolute zero || 2/10 || Kelvin (written with a lowercase 'k' as a unit, or as 'K', always without the degrees symbol '°') is a unit of temperature created by {{w|Lord Kelvin}}. It uses the same scale as Celsius but is shifted by 273.15 to set absolute zero at 0K (based on the {{w|Boltzmann constant}}.) While kelvins are very useful for {{w|thermodynamics}} and material physics, it can be unintuitive. Kelvin and Celsius are the most commonly used units in scientific measurements and calculations.
|-
| {{w|Fahrenheit}} || 32 || 212 || Outdoors in most places is between 0–100 || 3/10 || Fahrenheit (°F) is officially used in a few countries and informally in several others. It originated in a time when factors of 360 were favored in science over powers of ten, which is why the freezing and boiling points of water are set 180° apart. {{w|Daniel Fahrenheit}} chose not to base 0° on the freezing point of water, instead setting it at the coldest temperature he could achieve: the freezing point of an {{w|ammonium chloride}} {{w|brine}} solution. Although these reference points are now considered arbitrary and outdated by modern scholars, the scale gained popularity especially in Anglophone countries, likely because it aligns with everyday weather conditions and is intuitively useful. Its range covers typical temperatures across various latitudes and seasons, and 100°F is close to normal human body temperature. The Fahrenheit scale remains commonly used only in the U.S., Randall's home country, the Bahamas, Belize, the Cayman Islands, Palau, and Liberia.
|-
| {{w|Réaumur scale|Réaumur}} || 0 || 80 || Like Celsius, but with 80 instead of 100 || 3/8 || Often abbreviated to °Ré, a historical French system used in some places until the early 20th century. In modern times mostly used in cheesemaking. The rating (3/8) is a joke on the boiling point of water in this system being 80 instead of 100 as it is in Celsius; converting this to an out-of-ten scale would give 3.75/10, labelling it as more cursed than Fahrenheit but less so than Rømer.
|-
| {{w|Rømer scale|Rømer}} || 7.5 || 60 || Fahrenheit precursor with similarly random design || 4/10 || Usually abbreviates as °Rø, created by the Danish astronomer Ole Christensen Rømer in around 1702, while the Fahrenheit scale was proposed in 1724. Much like Fahrenheit, it uses the freezing point of ammonium chloride brine as the benchmark for 0°, and the scale is built with factors of 360 in mind with the boiling point of pure water at 60°. Like the Fahrenheit scale, the freezing point of pure water was not originally considered significant by Ole Rømer, but the scale was later updated to fix it to 7.5. The scale is also the last common ancestor of Celsius and Fahrenheit, as Reuamur was inspired by it, and Celsius by Reamur, and Fahrenheit specifically wanted a Rømer scale with more steps to avoid using decimals.
|-
| {{w|Rankine scale|Rankine}} || 491.7 || 671.7 || Fahrenheit, but with 0°F [''sic;'' should be 0°R] set to absolute zero || 6/10 || As the chart mentions, Rankine (°Ra) is to Fahrenheit what kelvin is to Celsius, an absolute scale rather than a relative one. The scale is mostly obsolete, but is still occasionally used in legacy industrial operations where absolute temperature scales are required. By rating, it is inexplicably more "cursed" than the otherwise identical Fahrenheit, ''despite'' being rooted at a more practical zero-point. [[2292: Thermometer]] expresses disdain for this scale.
|-
| {{w|Newton scale|Newton}} || 0 || 33-ish || Poorly defined, with reference points like "the hottest water you can hold your hand in" || 7-ish/10 || Created by Isaac Newton, measuring "degrees of heat", usually given the °N symbol. The cursedness rating (7-ish/10) is a joke about the vagueness of the scale's definition.
|-
| {{w|Wedgwood scale|Wedgwood}} || –8 || –6.7 || Intended for comparing the melting points of metals, all of which it was very wrong about || 9/10 || Created by potter Josiah Wedgwood in the 18th century. The measurement (°W) was based on the shrinking of clay when heated above red heat, but was found to be very inaccurate. The comic has a typo, as the scale is called Wedgwood (''without the e'').
|-
| Galen || –4? || 4?? || Runs from –4 (cold) to 4 (hot). 0 is "normal"(?) || 4/–4 || {{w|Galen}}, in his medical writings, is said to have proposed a standard "neutral" temperature made up of equal quantities of boiling water and ice; on either side of this temperature were four degrees of heat and four degrees of cold, respectively. The rating (4/–4) is a joke about the scale (with no common abbreviation) being defined between positive and negative 4, and at face value could be interpreted as –100% cursedness (the least of all those given), though it's not clear what negative cursedness would mean, or "cursedness" itself.
|-
| {{w|Celsius#History|''Real'' Celsius}} || 100 || 0 || In Anders Celsius's original specification, bigger numbers are ''colder''; others later flipped it || 10/0 || Most scales' temperatures can be indefinitely large, but have an absolute minimum temperature. By starting at a maximum value and counting down, this scale is indeed cursed, as nearly all possible temperatures (an indefinite range of them) will be negative. The rating (10/0) is a joke on the scale "flipping" the fixed points of modern Celsius. Division by zero is problematic, so this rating may either be undefined/undefinable or "infinitely" cursed.
The original logic was that zero could be easily calibrated to the height of a column of mercury at the temperature of boiling water, and further measurements then made of the amount it ''reduced'' in height under cooler conditions. This direction 'survives' in the historic {{w|Delisle scale}}, which predates (and arguably helped greatly inspire, though with a different factor) the classic version of °C. The version originally used by Anders was only 'corrected' posthumously, but nobody seemed bothered enough to do the same with Delisle's scale.
|-
| [https://physics.stackexchange.com/questions/459851/john-daltons-temperature-scale#459863 Dalton] || 0 || 100 || A nonlinear scale; 0°C and 100°C are 0 and 100 Dalton, but 50°C is 53.9 Dalton || 53.9/50 || {{w|John Dalton}} proposed a logarithmic temperature scale. The scale is defined so that absolute zero is at negative infinity, with the exponent chosen to match Celsius at 0 and 100. While Dalton temperature is defined for all positive and negative numbers, the nonlinear scale is difficult to work with since the amount of heat represented by a change of one degree Dalton is not constant. Degrees Dalton differs from Celsius by as much as 3.9 degrees between 0 and 100, but diverges much more for more extreme temperatures.

The rating (53.9/50) is a joke about the unit, as 53.9 Dalton would be 50 degrees Celsius — i.e. the cursedness could be understood as 50/50 (or 10/10, entirely cursed), but perhaps instead as 107.8% (even more than entirely cursed).
|-
| °X || 42.9 || 151.4 || '''Title text:''' "In my new scale, °X, 0 is Earths' [sic] record lowest surface temperature, 50 is the global average, and 100 is the record highest, with a linear scale between each point and adjustment every year as needed." || ''not provided'' || The {{w|Lowest temperature recorded on Earth|record lowest surface temperature on Earth}} as of 2024 is –89.2°C (–128.6°F), recorded at the {{w|Vostok Station|Vostok Research Station}} in Antarctica on July 21, 1983.[https://wmo.asu.edu/content/world-lowest-temperature] The average surface temperature as of 2023, the most recent available, is 14.4°C (57.2°F.)[https://climate.copernicus.eu/climate-indicators/temperature] The {{w|Highest temperature recorded on Earth|record highest temperature}} is 56.7°C (134.1°F), recorded on July 10, 1913 at {{w|Furnace Creek, California|Furnace Creek Ranch}} in Death Valley, California.[https://wmo.asu.edu/content/world-highest-temperature] "Surface" temperatures are measured at 1.5 meters above ground inside a shaded shelter, to accurately represent the temperature of the air, because temperatures closer to the ground are often much different.

{{cot|Derivation and graph}}
To break the scale into two linear parts (below and above 14.8°C), we define two separate equations for each range:

1. Below 14.8°C (from –89.2°C to 14.8°C):
* 0 °X corresponds to –89.2°C
* 50 °X corresponds to 14.8°C

We calculate the slope m₁:

<center>m₁ = (50 – 0) / (14.8 – (–89.2)) = 50 / (14.8 + 89.2) = 50 / 104 ≈ 0.48</center>

Now, using the point (14.8°C, 50 °X), we calculate the intercept b₁:

<center>50 = 0.48 × 14.8 + b₁</center>

<center>50 = 7.1 + b₁</center>

<center>b₁ = 50 – 7.1 = 42.9</center>

Thus, the equation for temperatures '''below 14.8°C''' is:

<center>'''X = 0.48 × C + 42.9'''</center>

2. Above 14.8°C (from 14.8°C to 56.7°C):
* 50 °X corresponds to 14.8°C
* 100 °X corresponds to 56.7°C

We calculate the slope m₂:

<center>m₂ = (100 – 50) / (56.7 – 14.8) = 50 / 41.9 ≈ 1.19</center>

Now, using the point (14.8°C, 50 °X), we calculate the intercept b₂:

<center>50 = 1.19 × 14.8 + b₂</center>

<center>50 = 17.6 + b₂</center>

<center>b₂ = 50 – 17.6 = 32.4</center>

Thus, the equation for temperatures '''above 14.8°C''' is:

<center>'''X = 1.19 × C + 32.4'''</center>

;Freezing and Boiling Points

Freezing point of water (0°C): Since 0°C is below 14.8°C, we use the equation X = 0.48 × C + 42.9:

<center>X = 0.48 × 0 + 42.9 = 42.9</center>

So, the freezing point is 42.9 °X.

Boiling point of water (100°C): Since 100°C is above 14.8°C, we use the equation X = 1.19 × C + 32.4:

<center>X = 1.19 × 100 + 32.4 = 119 + 32.4 = 151.4</center>

So, the boiling point is 151.4 °X.

[[File:XvsC.png|400px|center]]

See also [[2701: Change in Slope]] for a general discussion of separate linear scales between three points.
{{cob}}
Due to high and average temperature records now being broken nearly every year as a result of {{w|climate change}}, Randall's new °X scale must be re-calibrated each year. While extreme values like Absolute Zero or the {{w|Tungsten#Physical properties|melting point of tungsten}} will shift more significantly over time, while everyday temperatures will vary less.

2941: Cell Organelles

}}

==Explanation==
{{incomplete|Created by a GOLGI ENDOPLASMIC RETICULUM. Do NOT delete this tag too soon.}}

This comic depicts a {{w|Cell (biology)|biological cell}} diagram with a mix of real and fictional {{w|organelle}}s, blending accurate {{w|Cell biology|cell biology}} terms with misplaced or absurd labels. While it includes actual cell components like the nucleus, mitochondria, and Golgi apparatus, it also includes unrelated concepts from various fields such as geology, engineering, software, and pop culture. Labels like "evil endoplasmic reticulum" and "sticky endoplasmic reticulum" make fun of scientific terms. The comic plays on the complexity and diversity of cell structures by mixing in unrelated and humorous terms, highlighting the often confusing and intricate nature of scientific diagrams with clever wordplay and cross-disciplinary jokes.

The title text adds a humorous fictional backstory to the {{w|Golgi apparatus}}, an essential cell organelle involved in processing and packaging proteins. It playfully suggests that {{w|Camillo Golgi}}, the scientist who discovered the Golgi apparatus, was originally an independent organism. This organism was supposedly absorbed into our cells, where it then started working on what is now known as the Golgi apparatus. The joke is a satirical take on {{w|Symbiogenesis|endosymbiotic theory}}, which posits that certain organelles within {{w|Eukaryote|eukaryotic}} cells, like {{w|mitochondria}} and {{w|chloroplasts}}, originated from independent symbiotic {{w|Prokaryote|prokaryotic organisms}} that were absorbed by a host {{w|germ cell}}. Golgi appears to be depicted in the comic as a tiny alien being.

:Both the paragraphs and the table have been edited so far from what ChatGPT pretty obviously came up with (almost all of which I would say merit inclusion unaltered, [https://www.explainxkcd.com/wiki/index.php?title=2941:_Cell_Organelles&diff=343604&oldid=343601 looking at the initial edits; although there is evidence that the LLM output was copyedited and wikilinked in a way that it would probably not do,] i.e., we use the {{tl|w}} template here which is not at all a Mediawiki standard, the Wikimedia wikis having a different form <nowiki>[[w:...]]</nowiki>) so whatever deleterious LLM contamination they had has surely been beat out of them at this stage. Perhaps the GenAI deletionist is trying to encourage others to not fall prey to reliance on LLMs? A worthy goal, but I agree paraphrasing is far superior.

To me, 'Drain plug' is an engine oil-drain plug. Yes it is a bolt, rarely used in biological systems. But a cell and an engine are normally full of fluid, while plumbing sinks are normally empty. --[[User:PRR|PRR]] ([[User talk:PRR|talk]]) 02:10, 4 June 2024 (UTC)

1766: Apple Spectrum

2024-03-31T17:05:39Z

172.71.147.64:

{{comic
| number = 1766
| date = November 30, 2016
| title = Apple Spectrum
| image = apple_spectrum.png
| titletext = If I were trapped on a desert island, and could have an unlimited supply of any one type of apple, I'd be like, "How did this situation happen?"
}}

==Explanation==

The comic shows a {{w|spectrum}} of different types of apples, with {{w|Red Delicious}} towards the bad end of the spectrum, and {{w|Honeycrisp}} towards the good end of the spectrum. Although most spectra are only one-dimensional, {{w|Granny Smith}} is on some side branch, implying that the taste is so different from the other two that it deserves its own category. (Granny Smith apples have a distinctively tart, or sour, flavor with a subtle sweetness, and is commonly used for cooking, as opposed to the other mentioned varieties that are quite sweet and primarily eaten raw.) [[Randall]] has previously shown his disdain for Red Delicious apples in footnote 1 in [https://books.google.com/books?id=tgZIBAAAQBAJ&lpg=PP1&pg=PA97#v=onepage&q&f=false this what if]; he also ranked green apples as tastier than red apples in [[388: Fuck Grapefruit]]. The labeling of Red Delicious as "bad" compared to apples in general is perhaps unwarrantedly uncharitable; most apple trees produce fruit so bad that it is considered unfit for any purpose but fermentation.{{actual citation needed}} On the rare occasions that a tree naturally produces palatable apples, it is grafted onto other trees so that they will produce more of its apples instead of their own--all Granny Smiths are genetically identical. For a long time, though, in the US apples were mainly divided into three sorts. In case of the Red Delicious apples the color, not the taste was deemed most important to the buyers which (along with the genetic variability of Red Delicious) led to many Red Delicious apples breeds that looked great, but actually tasted bad, leading to a big restructuring of the apple market.

In the title text, Randall observes a common type of hypothetical question designed as a creative way to inquire about a person's preferences: If he were on a desert island with an unlimited access to something they like -- in this case, unlimited supply of any one type of apple -- what would he choose? However, Randall gives an unorthodox and unexpected answer to the typically playful hypothetical by taking it literally and questioning how such a situation would occur. How did he get stuck on the island, and how did he get a literally unlimited supply of apples? In reality, a desert island is unlikely to have an unlimited supply of any food,{{Citation needed}} let alone apples.

Randall's opinions on Red Delicious apples were referenced again in the title text for [[2820: Inspiration]].

Do Cacti Dream of Electric Sheep? --[[Special:Contributions/108.162.238.180|108.162.238.180]] 01:29, 17 May 2015 (UTC)

My theory: the cactus was draw first. It is a much higher quality drawing than the sheep or electricity, so it was probably drawn separate. Later, he drew a sheep zapping it... doesn't explain much, but does agree with the theory that the sheep is zapping the cactus. Also, [[Special:Contributions/173.245.56.180|173.245.56.180]] 21:09, 23 May 2015 (UTC)

I'm confused; did he erase the lines in the grid when he drew the lightning cloud? Otherwise, why wouldn't the grid lines show? [[Special:Contributions/173.245.56.172|173.245.56.172]] 16:27, 21 July 2015 (UTC)
: He did color in. See the partial grid lone at bottom right. If you look very closely, you'll see mostly yellowish shade inside the cloud. Not sure what technique it is, but looks like white and yellow mixed together. [[Special:Contributions/108.162.238.163|108.162.238.163]] 00:31, 17 October 2015 (UTC)
:: Looks like the grid lines were covered by thin yellow drawn lines (there's a place on the upper left of the cactus where the drawn line doesn't align very well with the actual grid line). I think there are also thin drawn yellow lines in other directions (especially visible in the lower right part). [[Special:Contributions/172.68.10.83|172.68.10.83]] 14:46, 17 September 2016 (UTC)
