Currently to me the header text is in German (as I live in Germany):&lt;br /&gt;
:Triff Randall Munroe in Berlin am 15. Oktober 2019!&lt;br /&gt;
:Hier die deutsche Ausgabe vorbestellen!&lt;br /&gt;
(Meet Randall Munroe in Berlin on 15th of October 2019! Preorder the german version here) where &amp;quot;Hier&amp;quot; (here) is a link.&lt;br /&gt;
4 odd things I noticed about this:&lt;br /&gt;
*It mentions the German version, but not the German verison of what. The book isn't even mentioned.&lt;br /&gt;
*When I (re)load the page, for a moment I get the image about winning a stick-figure-sketch of myself.&lt;br /&gt;
*XKCD does not use means like other pages (e.g. [[713: GeoIP]] to identify my language. As I am using a swedish VPN, I usually get advertisements in swedish (and redirections to swedish homepages, etc.). Maybe it is my browser settings which are set to German. Can someone identify the method used?&lt;br /&gt;
*The link leads to &amp;quot;https://www.xkcd.com/%22https://www.randomhouse.de/Buch/HOW-TO-Wie-man-s-hinkriegt/Randall-Munroe/Penguin/e547637.rhd?utm_source=autorenblog&amp;amp;utm_medium=banner&amp;amp;utm_campaign=how_to\%22&amp;quot; - a 404 page. (getting rid of the part before the 2nd https gets you to the page of the german publisher.&lt;br /&gt;

Yeah there is, in the UK the text changes to &amp;quot;I'll be coming to the UK for [https://xkcd.com/how-to/#tourdates the book tour].&amp;quot; There is Javascript in the page which sends a request to https://c.xkcd.com/how-to/news which is simply redirected (for me to https://xkcd.com/ukNews ) presumably based on GeoIP, definitely not a browser locale setting. Not sure how you would get them all, maybe iterate country codes through the start of the URL? I tried deNews which worked.

:&amp;quot;Huge World&amp;quot; would imply that the game type is first or third person, with the player taking control of a character in that world.

To be honest I think this comic is a bit lazy for xkcd standards. The whole joke of &amp;quot;I went outside today, the graphics are amazing but controls suck&amp;quot; is years old and was never really good in my opinion. I've seen several comics where Randal reused old jokes and put a clever spin on them or extended them in a new fashion that I'm disappointed Randall essentially copy&amp;amp;pasted this one.

I'm reminded of [https://www.smbc-comics.com/comic/2014-09-26 this comic] by the SMBC guy (better known as Emergency Backup Randall Munroe) which features a hypothetical site which can host such a review, and also two Black Hats.  Some folks also made a subreddit that actually implements the idea.  --[[Special:Contributions/172.68.11.167|172.68.11.167]] 18:03, 21 August 2019 (UTC)  &lt;br /&gt;

&lt;hr /&gt;

| number    = 2118&lt;br /&gt;
| date      = March 1, 2019&lt;br /&gt;

| image     = normal_distribution.png&lt;br /&gt;
| titletext = It's the NORMAL distribution, not the TANGENT distribution.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by PEOPLE NEW ENOUGH TO STATISTICS TO NOT LEAVE IN ANNOYANCE. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}&lt;br /&gt;
[[File:Standard_deviation_diagram.svg|thumb|{{w|Normal distribution}}s and the intervals of the standard deviation are a topic commonly seen in introductory statistics.  Randall's chart is similar, but his lines are perpendicular.]]&lt;br /&gt;
In statistics, a {{w|Probability distribution|distribution}} is a representation that can be understood in terms of how much of a sample is expected to fall into either discrete bins or between particular ranges of values.  For example, if you wanted to represent an age distribution using bins of ten years (0-9, 10-19, etc.), you could produce a bar chart, one bar for each bin, where the height of each bar represents a count of the portion of the sample matching that bin. To turn that bar chart into a distribution, you'd get infinitely many people (technically: a number N which tends to infinity), put them into age bins that are infinitely narrow (technically: bins whose size is O(1/sqrt(N))), and then divide each bin count by the total count so that the whole thing added up to 1. It is common to ask how much of the distribution lies between two vertical lines; that would correspond to asking what percent of people are expected to fall between two ages.&lt;br /&gt;
&lt;br /&gt;
Many statistical samplings resemble a pattern called a &amp;quot;{{w|normal distribution}}&amp;quot;.  A theoretically perfect normal distribution would have an infinite sample size and infinitely small bins.  That would produce a bar chart matching the shape of the curve in the comic.&lt;br /&gt;
&lt;br /&gt;
The area between two vertical lines of the distribution represents the probability that the value is between the x-values of the lines, and the total area is 1. Randall finds the area between two ''horizontal'' lines instead, which is mathematically meaningless, because the y-axis of a probability distribution represents {{w|absolute magnitude|magnitude}} as a fraction of unity (although we do have half of the normal curve between the two lines). The items represented by the magnitude at any given horizontal position are indistinguishable, unordered, and interchangeable; the idea that one could be above another is meaningless, and the fact that two items happen to fall at the same position on the y-axis doesn't mean they have anything in common. So, the comic explores the humor of annoying people by deliberately misunderstanding their work.&lt;br /&gt;
&lt;br /&gt;
An alternative explanation is that Randall has invented a new probability distribution, that we could call the ''tangent distribution'' (from the title text), the ''Munroe distribution'', or something of the sort.  This distribution is defined as follows: consider the area between the curve in the comic and the horizontal axis, and consider a random point (X, Y) uniformly distributed in that region.  Then X has the normal distribution and Y has the tangent distribution.  Areas between vertical lines in the comic give probabilities about X, and areas between horizontal lines in the comic give probabilities about Y.  So the comic gives a correct statement that the interval of Y values that is 52.682% of the range of Y centered at the midpoint of the range has probability 1/2.  Great!  Except this distribution has never been discussed before because it has no known application.  Moreover, it makes no sense to talk about intervals centered at the midpoint of the range because the distribution of Y is not symmetric: the midpoint of the range is neither the mean, the median, nor the mode.  So even if this distribution were interesting, the probability in the comic is not a good way to describe it!  We do use such intervals for the normal distribution because the normal distribution is symmetric, and the center of symmetry is the mean, median, and mode.&lt;br /&gt;
&lt;br /&gt;
The title text refers to the {{w|Normal (geometry)|normal line}}, which is perpendicular to the {{w|tangent}} line at a given point. Given a shape of interest, a normal line points perpendicularly away from it at a point, making a 90-degree angle with it in all directions, while a tangent line crosses a point on it and is exactly parallel to it at that point. The normal line is not at all related to the normal distribution, as the former is a geometry concept and the latter is probability/statistics one. Saying this to a statistician would only annoy the statistician further. This refers to the fact that the diagram attempts to divide the graph with horizontal lines when such a division would usually be done with perpendicular vertical lines.&lt;br /&gt;
&lt;br /&gt;
And this is annoying to a probabilist or statistician not only because the terms ''normal'' and ''tangent'' are come from differential geometry and have no established meaning in probability theory.  Even the word ''perpendicular'' has no established meaning in probability theory.  Of course, the x and y coordinates in the comic are perpendicular (orthogonal) coordinates, but X and Y are not &amp;quot;perpendicular&amp;quot; or &amp;quot;orthogonal&amp;quot; random variables.  Even if we give &amp;quot;perpendicular&amp;quot; or &amp;quot;orthogonal&amp;quot; a probabilistic meaning, and the most obvious such meaning is either {{w|Independence (probability theory)|independent}}, which even uses a symbol related to the geometric symbol for perpendicularity, or {{w|Uncorrelatedness (probability theory)|uncorrelated}}, which makes X and Y orthogonal vectors in the Hilbert space of random variables that are square integrable with respect to Lebesgue measure, X and Y are not perpendicular in either of these senses.&lt;br /&gt;
&lt;br /&gt;
So the more probability and statistics you know, the more annoying (ha, ha) this comic becomes.  It is not just about confusing novices.&lt;br /&gt;

&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by a SMALL CAT WITH NO CONCEPT OF FIELD EQUATIONS. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}&lt;br /&gt;
This comic is primarily a wordplay joke about the {{w|Schwarzschild radius}}, or the radius surrounding a black hole corresponding to the {{w|event horizon}}. The event horizon, in turn, is the limit from which nothing can leave a black hole. The joke is that, apparently, smaller cats are cuter, and there is a limit below which a sufficiently small cat (but larger than zero) will approach infinite cuteness, in a similar pattern to the way time's rate for an observer will approach infinity, the closer they get to the event horizon of a black hole.   &lt;br /&gt;
&lt;br /&gt;
It's also a reference to the {{w|Schrödinger's cat}} thought-experiment, since the names (Erwin) &amp;quot;Schrödinger&amp;quot; and (Karl) &amp;quot;Schwarzschild&amp;quot; are somewhat similar and both men were interested in quantum physics.&lt;br /&gt;
&lt;br /&gt;
The title text makes multiple allusions. First, it alludes to what happens when an object falls into a black hole. From an outside observer's point of view, such objects appear to slow down and take an infinite amount of time to cross the Schwarzschild radius due to the time dilation of {{w|General relativity}}. The object's photons will become increasingly red-shifted, fading as they lose energy to the black hole's gravity well.&lt;br /&gt;

:[A graph is shown. The x-axis is labeled &amp;quot;Cat size&amp;quot; and the y-axis, &amp;quot;Cat cuteness&amp;quot;. Parallel to and a short distance from the y axis is a dashed line the same length as the y-axis line; the space between the y axis and the dashed line is labelled &amp;quot;Critical Limit&amp;quot;. Graphed is a function coming down from infinity, starting close to the dashed line; it then levels off and does not reach zero on-screen. At the top end of the graph is the text &amp;quot;Schwarzschild's Cat&amp;quot; and an arrow pointing upwards outside of the graph.]&lt;br /&gt;

There was yet another round of articles about millennials killing certain markets by not buying the product; The overriding correlation? Lack of money.

I have made an attempt at fixing the table in the transcript. Not sure if this is what you had in mind, but it's quite difficult to find a way to express the information without using a table - I understand the reasons why tables in the transcript are bad, but there is also reason why tables are good for communicating information!

&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Transcript tables are bad. not really sure how to replace this one Do NOT delete this tag too soon.}}&lt;br /&gt;
Another of [[Randall|Randall's]] [[238: Pet Peeve 114|many]] [[:Category:Pet Peeves|Pet Peeves]], this time it's statistics. It is the first in more than four years, since [[1368: One Of The]].&lt;br /&gt;
&lt;br /&gt;
&amp;quot;{{w|Millennials}}&amp;quot; are the generation of Westerners who were born between the early 1980s and the late 1990s, whereas {{w|baby boomers}} are the generation born during the &amp;quot;baby boom&amp;quot;, a period of high birth rates from the late 1940s to early 1960s. A common headline on news websites is &amp;quot;Millennials are killing the X industry&amp;quot; where X is a product whose sales have dropped in recent years, such as [https://ezplaytoys.com/pages/products jungle gyms for kids]. One of the most famous is the {{w|diamond industry}}, where a combination of the {{w|wage gap}}, stigma over {{w|Blood diamond|conflict diamonds}}, and less desire to get married early has seen millennials buying less diamond jewelry than previous generations.&lt;br /&gt;
&lt;br /&gt;
Randall spoofs this idea. In the comic, [[Cueball]], as a [[:Category:News anchor|news anchor]], presents a heading which opens his story by asking if millennials are killing the industry of surgical {{w|Joint replacement|joint replacements}}, illustrating it with numbers of joint replacement procedures among millennials compared to baby boomers. The joke is that millennials are simply too young for most of them to need joint replacements (which are usually used to treat senile {{w|osteoarthritis}}), so most people will see that so there really isn't a news story here. Randall is using this example to highlight that this kind of story is ridiculous. Millennials will likely need joint replacements in the future as they get older, potentially keeping sales of joint replacements at close to their current rate.&lt;br /&gt;
&lt;br /&gt;
A '''{{w|cohort effect}}''' is a cultural difference between generations (such as buying fewer diamonds), whereas an '''age effect''' is one that is simply related to getting older (such as getting arthritis). Joint replacement rates are an age effect, but the newscast is presenting them as if they were a cohort effect. (More correctly, the table rows would be labelled e.g. “people aged 50–70” and “people aged 25–35”.)&lt;br /&gt;
&lt;br /&gt;
The title text points out that although numbers of millennials receiving joint replacements are low, they are higher than the numbers of baby boomers who received them ''at the same age''—i.e. in their 20s—due to advances in medical diagnosis and technology in the last 50 years, as well as (in some countries at least) better access to healthcare. This statistic can be used to create a headline which is the reverse of the one in the comic, namely &amp;quot;millennials are getting more joint replacements than ever&amp;quot;. Randall notes that you could therefore use either headline to back up your argument, depending on the agenda you are trying to present.&lt;br /&gt;
&lt;br /&gt;

:Cueball: Tonight: Are Millennials killing the joint replacement industry?&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:[To the left of Cueball is a presentation which includes a two by two table with a header above the table. Each of the two rows and columns are labeled, with rows entitled 'Baby Boomers' and  'Millennials', and columns entitled 'Knee' and 'Hip']&lt;br /&gt;

It was actually called &amp;quot;the first World War&amp;quot; in 1914. However it wasn't called &amp;quot;The First World War&amp;quot;, as the name was to show that it was a world war, not to point out that another would happen in 20 years. And the name &amp;quot;Great War&amp;quot; referred to the Napoleonic War, not the First World War. And now to leave a message beginning with four tildes.
