Ke4roh: Feeling old

Ok transcript hopefully complete, but please check it over, as I did it while tired and staying up late waiting for the election results. [[User:Wyrme|Wyrme]] ([[User talk:Wyrme|talk]]) 05:43, 9 November 2016 (UTC)

: Spoiler alert: Trump won. --[[User:JayRulesXKCD|JayRulesXKCD]] ([[User talk:JayRulesXKCD|talk]]) 16:16, 9 November 2016 (UTC)

The main idea of the comic is stated in the first sentences "If they're [age], you say: "Did you know [thing] has been around for the majority of your life?"
The majority of your life means "more than half your life". For each of the age stated in the comic, something that happened more than half the age ago is stated.
As an example for the first two:
Grand Theft Auto IV was released in 2008, which is 8 years ago. More than 8 years is at the same time more than half of 16 years, which means "the majority of a 16 year old's life"
The next one goes for Rickrolling, which is "a prank and an Internet meme involving an unexpected appearance of the music video for the 1987 Rick Astley song 'Never Gonna Give You Up'. The meme is a type of bait and switch using a disguised hyperlink." according to [https://en.wikipedia.org/wiki/Rickrolling wikipedia]. Even if the first reference is from 2007, the same Wiki page says that 'By May 2008, the practice had spread beyond 4chan and became an Internet phenomenon'. May 2008 is more than 8 and a half years ago which is more than half of 17 years.
It goes on and on, with "Aqua Teen Hunger Force Colon Movie Film for Theaters" which is a 2007 American Flash animated surreal comedy film", which again is more than 9 years ago and so on.
Sorry if I'm not clear enough but I hope you got it.

: Yeah, the "majority part" is a bit confusing. I looked up 35 and saw "The Matrix" and I was like "wait, that didn't come out 35 years ago?!". Well, it didn't and that's not what the comic implys. However, it has been around for a MAJORITY (= more than half) of my life. [[Special:Contributions/162.158.202.141|162.158.202.141]] 12:37, 9 November 2016 (UTC)

I'm only 32, but saddened at the entry for 40. C&H was (and still is) one of my favorites. I say we all just take off today and play some Calvinball. Who's with me? [[Special:Contributions/162.158.69.100|162.158.69.100]] 12:48, 9 November 2016 (UTC)

There is this last thing "over 41, we don't care" which I cannot really explain. Maybe the 40+ year olds seen all of these later in their life but why stop at this point? (which is around 1996, according to the "rules")? The internet has been around since way before that and if we take the first popular browser this was about 1993 or so. That would take us to 46. Is there any specific event which might be a reason to stop at 41? [[User:Anarhistu|Anarhistu]] ([[User talk:Anarhistu|talk]]) 13:12, 9 November 2016 (UTC)
: No, people above 40 already feel old, no need for a chart --[[Special:Contributions/162.158.88.204|162.158.88.204]] 13:18, 9 November 2016 (UTC)

:::He has previously stopped at a given age and stated that anyone older should feel old already --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 20:43, 9 November 2016 (UTC)

But if I look in x years, then the entry at current age + x will have been there for (current age +x)/2 + x years, so if I look at it again after my age has doubled, the thing has been there for my entire life.
--[[Special:Contributions/162.158.88.204|162.158.88.204]] 13:17, 9 November 2016 (UTC)
:Sorry your are completely wrong. If you are 20 now and look at something happening 10 years ago. Then when you are twice as old (40) you look at the same ting and that will then be 30 years old. It will always be 10 years younger than you. There was a mistaken explanation of the title text saying something like what you say, and now I have corrected it. He just means that if you show them this chart again when their age has doubles, you can say that this chart has now existed in the majority of your life. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 20:43, 9 November 2016 (UTC)

Heh. Randall isn't always prompt in posting new comics early on M/W/F, but this one went up promptly at 12:01am. He deserves to be embarrassed after the communist comic he posted on Monday. [[Special:Contributions/172.68.55.83|172.68.55.83]] 13:31, 9 November 2016 (UTC)
:How the hell did you make out Clinton to be a communist? It's Trump who likes Putin, where Clinton would be more against him... I guess he just thought people needed something that could distract them from the election, since most of his readers (especially after his previous comic) would have rooted for Clinton because of their fear that Trump won. On the other hand most people probably feels old today, after the election, so in that way the comic is a bit of a waste... --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 20:43, 9 November 2016 (UTC)
::Sorry, but we Americans disagree with you. Too bad, so sad. {{unsigned ip|172.68.55.83}}
::: Actually, we Americans chose Clinton, probably by a margin of >1M votes once CA and OR finish counting. [[User:Miamiclay|Miamiclay]] ([[User talk:Miamiclay|talk]]) 22:40, 11 November 2016 (UTC)

I don't understand how this is supposed to work. If I wanted to make someone feel old, I would pick an event that they think is fairly ancient and tell them: "do you realize you're *more* than twice as old as this?" Here, Randall does the opposite, he says: "did you know you're *less* than twice as old as this", so what? E.g. "Twitter has been around for a majority of your life" is true of anyone who is 0 to 20, so how is it supposed to make a 20-year-old feel old? Did Randall get his comic backwards or am I missing something?
Zetfr 14:26, 9 November 2016 (UTC)
:The idea is that you don't pick events that they think are ancient, you pick events that they think are recent. [[Special:Contributions/162.158.222.138|162.158.222.138]] 16:46, 9 November 2016 (UTC)

The explanation says "The titletext points out that the same chart can be used for the same person much later in their life. However, the major event shifts earlier and earlier into their life; when their age has doubled, the event in the chart has happend in the year of their birth." This makes no mathematical sense - the major event would shift earlier ''into their life'', but not ''in time'', and would remain the same distance from their birth year. What is probably intended is that now ''the chart itself'' will be around for a majority of their life (though I agree with the above commenter that it would probably make one feel young, not old). --[[Special:Contributions/172.68.10.90|172.68.10.90]] 14:54, 9 November 2016 (UTC)
:Exactly, what I wrote above to the other comment on this, and I have tried to correct it in the explanation. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 20:43, 9 November 2016 (UTC)

I fixed the rest of the blank explanations, such as Gmail, Nintendo Wii, and others. Please fill in the 'Aqua Teen Hunger Force', as I was not able to find information about it anywhere and I have not seen that show, nor the movie itself, so I cannot answer. --[[User:JayRulesXKCD|JayRulesXKCD]] ([[User talk:JayRulesXKCD|talk]]) 15:14, 9 November 2016 (UTC)

Actually Randall may be wrong with some of those entries at the current moment. Let's say that somebody is 19 years old, but their 20th birthday is on the 10th of November. The entry for their age is the Nintendo Wii which came 9 years, 11 months and 20 days ago (as of November 9), which is not more than half of the subject's age. I think this occurs on quite a few of those entries, so either the chart is intended to be addressed only to people during their birthdays, or one can make fun of any geek who parades this list for not being rigorous with their maths. [[Special:Contributions/108.162.246.35|108.162.246.35]] 15:38, 9 November 2016 (UTC)
: That's pretty pedantic. We're so close to the end of the year that we can reasonably assume it means "people who turned X years old in 2016" [[Special:Contributions/141.101.98.165|141.101.98.165]]
::I think he just goes for events that is approximately half as old as the person. Only error he seems to have made is with the Matrix, which came when the 35 years old of today was 18, and it has thus only been in their life about 17 years. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 20:43, 9 November 2016 (UTC)
:Pedantic? This is xkcd we're talking about. Not only that there's a post commenting on this comic's timing regarding the MWF pattern, as on every other similar comic, a fact that should be taken even less seriously, but Randall has greatly shown his support of pedants partly by repeatedly depicting them as empowered in his comics. I think that pedants have to either take responsibility for their demeanour or admit to the fact that their peculiarity does not even have the tradeoff of accuracy it should have. In other words, anyone who bothers others with a list like this better have precise information to offer if they expect to have any reason not to waste others' time.

You might be old if you remember watching the Berlin Wall being torn down on television.
You would be even older if you remember reading about the Berlin Wall at the time it was being built.
I remember both ... I read about the wall being built in elementary (primary) school current events. [[User:Rtanenbaum|Rtanenbaum]] ([[User talk:Rtanenbaum|talk]]) 21:30, 9 November 2016 (UTC)
:Interesting, but not strange, to bring that wall up today. Since it is today the anniversary for it's destruction in 1989 (17 years ago so would have been good for the 34 years old). And very ironic that a man is then elected on this very day who has promised to build and even bigger wall between his country and another. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 22:14, 9 November 2016 (UTC)
: If you want to feel really old, just remember that The Hoff sang "Looking for Freedom" in front of the Berlin Wall. ;) [[Special:Contributions/198.41.242.242|198.41.242.242]] 11:01, 10 November 2016 (UTC)

::Auch I feel old now, that I could make such a mistake. Thanks for correcting it. But at least I'm not 54 yet, but I do remember the day very well. Just happy Randall raised the bar since his movie ages, so my age is still on the list and so I'm not just in the "rest above 41 group" ;-) --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 15:06, 10 November 2016 (UTC)

1733: Solar Spectrum

Ke4roh: "read of manually" -> "read off manually"

{{comic

| image = solar_spectrum.png
| titletext = I still don't understand why the Sun paid the extra money for Transitions lenses.
}}

==Explanation==
{{incomplete|Someone knowing more about the Fraunhofer lines could maybe improve the [[#Table of spectrum|table]] (mainly the comments).}}
This comic's release day was postponed from the scheduled Wednesday release to a [[:Category:Thursday comics|Thursday release]] because {{Citation needed}} of the popularity of the previous Monday comic [[1732: Earth Temperature Timeline]]. [[Randall]] even explained this in the header text, see [[1732#Popularity_of_comic|this trivia item from the previous comic]].

This comic depicts the {{w|Fraunhofer lines}}, i.e. the {{w|spectral lines}} seen when sunlight is split in a {{w|spectrometer}}. These appear as black gaps in the rainbow of light, caused by light being absorbed by {{w|Chemical element|elements}} in the {{w|Sun}}. The frequencies of light that an atom absorbs depend on the exact arrangement of electron orbitals around it - because each element has a different pattern of orbitals, each one has a distinctive pattern in the absorption spectrum. The chart shows most of the main lines in the visible spectrum and identifies the elements linked to them.

The image of the Fraunhofer lines from Wikipedia is shown below in the section with a [[#Table of spectrum|table]] of these lines. Here it can be seen that all the lines that are labeled are labeled with element are correctly labeled. Also all lines shown in the part of the spectrum included in the comic are included. Ten of the lines included are not labeled in the picture on Wikipedia (at least not with an element, two of the three "h" labels are not in the table on Wikipedia). Six of these also have no label in the comic. But the other four line's label ''Those giant sunglasses'' constitute the joke of the comic. There seem to be only one clear error in the comic and that is the fifth line labeled Sunglasses, the middle of the lines, which is actually a Hydrogen line (C in the picture below). But the line next to it to the right is one of those not labeled in either pictures and it seems likely that it was this line Randall meant to be a Sunglass line...

All ten extra lines (including both the labeled and unlabeled ones) seem to correspond to the [http://astro.u-strasbg.fr/~koppen/discharge/silicon.jpg spectrum of silicon], and '''the joke then refers to the {{w|silicon dioxide}} (aka glass)''' used in the lenses of the Sun's sunglasses. Of course, this means that the glasses have been ionized and turned into plasma by the heat of the sun.

The idea of a sun with sunglasses is a reference to pictures/clipart of the sun wearing sunglasses, often used to denote good weather. But Randall has specifically used this picture in his [[what if?]] ''{{what if|115|Into the Sun}}'' in the fourth image. The title text of that image even references the fact that those sunglasses will block the light to Earth:
:A partial solar eclipse is when the Earth moves across the part of the Sun blocked by its sunglasses.
So this comic is a direct callback to this what if? post.

There is another joke in drawing a sun with sunglasses because sunglasses are meant to protect your eyes from the sun, so what should they protect the Sun's eye from, Star light...? Also any glasses worn by he sun would they not become sun glasses?

{{w|Transitions Optical|Transitions}}® is a brand of {{w|Photochromic lens|photochromic lenses}}; however, photochromic lenses are often referred to as "transition lenses", so the title text does not necessarily refer to the brand. Photochromic lenses are a type of plastic lens used in prescription spectacles that allow the lens to turn dark when exposed to UV light such as that found in sunlight. The sun choosing to get transition lens would prove a waste of money as the lenses would be permanently transitioned to be dark, so a pair of ordinary sunglasses would likely have proved more cost effective. (Always assuming they do not turn into plasma when getting close to the sun...)

===Table of spectrum===
:This is the official image for {{w|Fraunhofer lines}} (solar spectrum) on Wikipedia:
:[[File:Fraunhofer_lines_From_Wikipedia.png]]
:The graph is a typical spectral lines chart, with a long rainbow band (from {{w|ultraviolet}} to the left to {{w|infrared}} on the right both colors appearing black as they are not visible.) The black lines in it, indicating the traces of different elements. Noe that the comic only covers the visible part of this spectrum.

*In the table below are the official labels from the picture above. If there are no label this is noted with ''none''.
**'''Note that they are labeled from right to left!'''
*Then the element causing the line is mentioned. ''Unlabeled'' is used if the line is not mentioned in the table from Wikipedia.
*Then follows the wavelength. It is given with decimals if it is noted in the table from Wikipedia. Else it has been read off manually from the picture above.
*Then follows the label given in this comic, with unlabeled meaning that it is not labeled in the comic but still shown.
**If the line is not even included in the xkcd comic "N/A" will be used.
**A number will be given after the xkcd label listing which number line on xkcd that has used this label. (Note going from left to right in the numbering).
*Finally a comment can be made on this.
**If the two labels fit, then ''agreement'' is noted.

1681: Laser Products

2016-05-16T20:27:16Z

Ke4roh: a word on laser eye surgery.

{{comic
| number = 1681
| date = May 16, 2016
| title = Laser Products
| image = laser_products.png
| titletext = ERRORS: HAIR JAM. COLOR-SAFE CONDITIONER CARTRIDGE RUNNING LOW. LEGAL-SIZE HAIR TRAY EMPTY, USING LETTER-SIZE HAIR ONLY.
}}

==Explanation==
{{incomplete|Initial draft outline. Please explain each technology, and elaborate on each combination. Maybe make a table similar to his but instead of reviews include explanations. Include wiki links. This comic is really good and deserves more explaining.}}
This comic takes three laser-based technologies - laser eye surgery, laserjet printers, and laser hair removal - and conflates them, with humourous results. These are illustrated through reviews by users of the resulting combinations. For the original combinations, the reviews are highly positive. For the new combinations, most are negative, because most of these new "technologies" are ill-conceived and possibly harmful.

"Laser eye surgery" gets a positive review, since it has successfully corrected the reviewer's vision, no longer requiring them to use glasses. However, "laser eye removal" would be very painful, and thus the review is negative, stating that the review had read the description incorrectly, likely believing it to be one of the real combinations on the chart. "Laser eye printer" refers to printing on (or possibly ''of'') an eyeball, which gets an "eww" response.

"Laser jet surgery" makes the reviewer nervous, as performing maintenance on a jet with lasers is potentially dangerous and could easily be done incorrectly. {{Citation needed}} Alternatively, "laser jet surgery" could mean laser surgery done on a human from a laser-mounted jet aircraft (unspecified whether the human being operated on is aboard that aircraft as well, another aircraft, or on land: in any case, not a safe idea. "Laser jet removal" implies the destruction of jets with lasers, which works, but angers the Federal Aviation Administration, and probably resulted in legal consequences for the reviewer. "Laserjet printing" gets a positive review, as it is legitimate printing technology that works well for the reviewer.

"Laser hair surgery" is rated negatively, noting how bizarre the phrase is and claiming that it was a very unpleasant haircut with the aftermath being the smell of burning hair. "Laser hair removal" is reviewed well, as it is a real process that effectively removes unwanted hair. "Laser hair printer" is negatively reviewed for being disgusting, the printer jamming, and the machine being unable to stop printing the hair. The title text expands on this, displaying a standard printer error message, replacing "paper" with "hair". It also replaces "ink" with "color-safe conditioner".

===Laser eye surgery===

LASIK, one of the more common laser eye surgeries, works by cutting open the cornea and ablating a small amount of the lens. Lasers are used for both steps. This, or equivalent, is the referenced surgery. There are other laser eye surgeries for various other conditions besides near- and far-sigtedness.

===Laserjet printing===

Laserjet printing, or more commonly known as laser printing, is an electrostatic digital printing process. It produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back and forth over a negatively charged cylinder called a "drum" to define a differentially-charged image. The drum then selectively collects electrically charged powdered ink (toner), and transfers the image to paper, which is then heated in order to permanently fuse the text and/or imagery. As with digital photocopiers and multifunction/all-in-one inkjet printers, laser printers employ a xerographic printing process. However, laser printing differs from analog photocopiers in that the image is produced by the direct scanning of the medium across the printer's photoreceptor. This enables laser printing to copy images more quickly than most photocopiers.

===Laser hair removal===

Laser hair removal is the process of removing unwanted hair by means of exposure to pulses of laser light that destroy the hair follicle. It had been performed experimentally for about twenty years before becoming commercially available in the mid-1990s. One of the first published articles describing laser hair removal was authored by the group at Massachusetts General Hospital in 1998.The efficacy of laser hair removal is now generally accepted in the dermatology community,[citation needed] and laser hair removal is widely practiced in clinics, and even in homes using devices designed and priced for consumer self-treatment. Many reviews of laser hair removal methods, safety, and efficacy have been published in the dermatology literature.
