I think he used horses as a reference to the unit of work, horse power, but in this case instead of being the 550 foot pounds per second, it is the force required to put a horse at that altitude<br />

:The top one clearly says "Spacecraft mass" and the bottom says "Capacity" (which is normally either the mass or volume something can hold), so I don't think either refers to force. [[Special:Contributions/173.245.54.175|173.245.54.175]] 08:32, 17 December 2014 (UTC)<br />
<br />
Horses might also be used as a length unit... I am wondering if this is somehow related to the size of SRBs [http://www.snopes.com/history/american/gauge.asp] ;-) {{unsigned|Ld75}}<br />
:There is the famous tail (no pun intended) of how the width of the Space Shuttles SRBs are related to the width of a horses, er, um, butt -- which apparently is not true. However, similarly to the "Upgoer Five", Randall may just be trying to relate a very difficult to grasp concept (weight of a huge object) to something that with which a large number of people may be familiar. [[User:Jarod997|Jarod997]] ([[User talk:Jarod997|talk]]) 14:34, 17 December 2014 (UTC)<br />
<br />
A few mass calculations: (All masses from wikipedia)<br />
<br />
* ISS - 450,000 kg / 932 Horses = 483 kg/Horse<br />
* Skylab - 77,088 kg / 171 Horses = 450 kg/Horse<br />
* Mir - 129,700 kg / 286 Horses = 453 kg/Horse<br />
* Shuttle Payload - 24,400 kg / 54 Horses = 452 kg/Horse<br />
* Compton GRO - 17,000 kg / 38 Horses = 447 kg/Horse<br />
<br />
It looks like Randall probably used 450kg as a standard horse, which seems like a fairly average weight for a {{w|Horse#Size and Measurement|horse}}. --[[User:Pudder|Pudder]] ([[User talk:Pudder|talk]]) 09:06, 17 December 2014 (UTC)<br />

Curious: the Atlas-Centaur rocket is listed as lifting Centaurs, not horses. [[Special:Contributions/141.101.98.244|141.101.98.244]] 09:11, 17 December 2014 (UTC)<br />
<br />
:Plus the Pegasus rocket is labelled as lifting one (mythical, horse-sized?) Pegasus. I took this as synchronicity, but currently someone (who missed the Centaur reference in the part of the main text about "joke additions/deviations") who edited the the main text seems to think that it's purely a mythical reference.

The Keyhole captions are wrong; assuming 450 kg/horse, 40 horses for the [[wikipedia:KH-7 Gambit|Keyhole 7]] would be around 18,000 kg. Documents declassified a couple of years ago give the mass as around 2,000 kg. The [[wikipedia:Corona (satellite)|Keyhole 3]] was even smaller. The mass and dates are about right for [[wikipedia:KH-11 Kennan|Keyhole 11]] satellites but I don't know where the 3 and 7 have come from (the dates are wrong for the third and seventh Keyhole 11s) [[Special:Contributions/141.101.99.85|141.101.99.85]] 09:43, 17 December 2014 (UTC)<br />

Initially I thought that the position of 'T Rex' along the X axis (approx 1985) may be a link to the band {{w|T. Rex (band)|T.Rex}}, but according to wiki that was 1967-1977.

The Oldsmobile is probably a reference to the movie ''{{w|Mom and Dad Save the World}}''.

'''Terrastar''' may be referring to [[wikipedia:TerreStar-1|TerreStar-1]], with a launch mass of 6,910 kg, divided by 15 horses is about 460 kg/Horse. This is consistent with the above calculations. [[User:Jarod997|Jarod997]] ([[User talk:Jarod997|talk]]) 14:23, 17 December 2014 (UTC)<br />

<br />
'''Thor''' may be referring to the [[wikipedia:Thor-Able|Thor-Able]] launch vehicle. First flight of 1958 (good position on the graph), and payload of 120 kg is about 40 kg / dog -- that's a bit high for an average, but depending on the breed it could be accurate. [[User:Jarod997|Jarod997]] ([[User talk:Jarod997|talk]]) 14:58, 17 December 2014 (UTC)<br />
:Yes, I believe that is correct. Added to tables. --[[User:Pudder|Pudder]] ([[User talk:Pudder|talk]]) 15:22, 17 December 2014 (UTC)<br />
<br />
Based on horse payload, location on X-axis (time of first launch?), and some general wikipedia browsing, I believe the unlabeled launch vehicle on the bottom is a Delta IV Medium. According to Wikipedia, it was first launched on 11 March 2003, which fits the location on the timeline. It had an LEO payload capacity of 9,420 kg, which equates to 20.9333333 horses at the estimation of 450kg/horse. For reference, all my information was pulled from http://en.wikipedia.org/wiki/Delta_IV#Delta_IV_Medium.

;Title Text Calcs<br />
<br />
I did some calculations on the title text, though I'm not sure how correct they are. We can use our standard horse at 450kg, and assuming 9.81m/s<sup>2</sup> gravity (neglecting the slight drop in gravity as it moves up the space elevator), the formula I've used is:<br />
<br />
<pre>1 Watt = 1 Newton raised 1 Metre in 1 Sec<br />
Power[Watts] = (450[kg] * 9.81[m/s<sup>2</sup>]) * LEO[m] / Time[s]</pre><br />
<br />
A large power station is a pretty vague measure, but I would guess we are looking at around 1GW. I found a 30 acre solar farm (in the not-so-sunny UK) with an output of 5MW, scaled linearly (which may well not be valid) a 0.6 acre (2500m<sup>2</sup> back yard could yield 93.5kW. Using these power guesstimates, we can calculate the altitude at which the 500 horses/year and 10 horses/minute converge. It works out at roughly 1350km. Depending on where you look, LEO is [https://www.google.com/search?q=Low+earth+orbit&rls=com.microsoft%3Aen-gb%3AIE-SearchBox&oe=UTF-8&gfe_rd=cr&gws_rd=ssl&oq=&gs_l= classified as anything under 2000km].<br />
<br />
Now I know there are a lot of assumptions in there, and really the whole formula is backwards, but hey... its a starting point! --[[User:Pudder|Pudder]] ([[User talk:Pudder|talk]]) 17:05, 17 December 2014 (UTC)</div>Dangerkeith3000https://www.explainxkcd.com/wiki/index.php?title=Talk:1437:_Higgs_Boson&diff=77655Talk:1437: Higgs Boson2014-10-22T15:29:36Z<p>Dangerkeith3000: </p>

==Explanation==<br />
{{incomplete|Just outline}}<br />
Many action/thriller movies, during the first few minutes, have a background [http://tvtropes.org/pmwiki/pmwiki.php/Main/ChekhovsNews news] [http://tvtropes.org/pmwiki/pmwiki.php/Main/CoincidentalBroadcast report] that foreshadows the onset of some kind of danger, such as shark attacks, nuclear warfare etc.<br />
<br />
Randall suggests taking the same approach to random news articles from real life, in order to make them more ominous.<br />
<br />
The title text references ABC's ''The View'' where two of the co-hosts, Sherri Shepherd and Jenny McCarthy, were simultaneously fired (or resigned -- sources vary), the day before this cartoon appeared.<br />
<br />
Also, North Korea's official Korean Central News Agency recently threatened the US over the Seth Rogen movie [https://en.wikipedia.org/wiki/The_Interview_%282014_film%29 The Interview], promising "stern" and "merciless" retaliation if the film is released. The threat has generated some hype for the yet unreleased movie.<br />

It may be a cultural-linguistic thing, but I felt compelled to change "cries" to "crying", in the explanation. Hearing "his cries" is redolent of "Ahoy there!" coming from a person attracting attention in a nautical context, the various distinctive calls of a person selling produce in a street-market or "I'm up here! Get me down!" from a person stuck on the ledge of a burning building. When a baby cries (as opposed to when someone "cries out") you hear him (or her... it's not actually specified) 'crying', not his(/her) 'calling-cries', even though both are indeed similar forms of attracting attention. I've overthought this, of course. [[Special:Contributions/141.101.99.57|141.101.99.57]] 15:19, 20 June 2014 (UTC)<br />

What I totally don't get is...when the visual information about Krypton's instability has reached Earth, Krypton has already exploded many years ago. I guess that Kal-El's spaceship is travelling at near-lightspeed, so time-dilation effects cause very little apparent time to pass for Kal-El; so when he arrives he's still a a baby. This assumes that (a) the alien technology allows for extraordinary acceleration while still maintaining survivable conditions for the baby (while Superman can apparently survive extreme conditions, this trait is most probably bestowed upon him only at the end of his journey by the Earth sun), and (b) the he is a male (this primary sexual characteristics are not shown in the movie, IIRC...). An FTL spaceship is out of the question, as this would mean that the Krptonite meteors would also have been travelling at FTL speed.<br />

:Whatever. By the time a spaceship from Earth arrives, even if it travels at near-lightspeed, Clark Kent will most probably be facing retirement already (after turning a crank for many years, of course).<br />
<br />
Btw, having Superman turn a crank instead of having him fight crimes would not necessarily mean that Lex Luthor would have had success with his evil plans. Mr. Bond, James Bond, had proven numerous times that he can stop any criminal who attempt to achieve world domination or at least extreme wealth via over-convoluted plans. Yep, I mean, if you could build powersats, you'd immediately achieve wold domination via your monopoly for "free and clean energy", so why bother with criminal plans? Any, if you are smart enough to build powersats, but cannot resist the temptation to use them for over-convoluted criminal plans, should yout net able to think about the option to give your Legion of Doom at least basic training in marksmanship?<br />

I actually thought this was more brilliant before I saw the second ship (rather: noticed that the crystal was a ship). I thought the gag was that some human, in attempting to resolve a crying baby (we've all been there, and if you haven't, don't knock it) actually created Superman (the shuttle destroys the unstable Krypton, and the baby is flung back). If anyone does think that this comic is gruesome, then stop reading it: your efforts could be rewardingly employed by criticizing "Cyanide and Happiness" instead. I love the quirkiness Randall!

I think this is a comment of the quality of education today - it is difficult to grade students on a distribution curve and even more so when you take into account the distribution curve of the teachers ability. {{unsigned ip|108.162.249.205}}<br />
<br />
I noticed the teacher's curve is symmetrical, and after further inspection it could be interpreted as an edge detection: high values show where an edge occurs. The two highest peaks would nicely align with the edges of the paper, the next highest peaks fit the edges of the table, and the rest could be approximation artefacts, as they're equidistant and rather insignificant compared to those four. I'm not statistics pro, but maybe that rings someone's bells? [[Special:Contributions/108.162.210.239|108.162.210.239]] 07:56, 26 March 2014 (UTC)<br />
<br />
:Interesting observation. It may play into an age-long legend told and re-told among the students that some teachers grade papers by tossing the whole pile in the air; those sheets that land on the teacher's desk get a pass, those falling to the floor get a fail. Sometimes the story gets modified in such a way that papers falling on the teacher's book (or other object) laying on the desk will get a higher marking than those simply hitting the desk. The latter version would explain the higher sheet-size-apart peaks. [[Special:Contributions/108.162.210.111|108.162.210.111]] 08:57, 26 March 2014 (UTC)<br />

Man, normally these explanations clear the comic right up for me, but I've read this one thrice now and I still can't figure out what a t-distribution is, much less a joke based on one. The only definition being a Wikipedia quote written in legalese doesn't help. So a t-distribution estimates...the probability of a population's average when there's unknown information?[[Special:Contributions/108.162.216.48|108.162.216.48]] 12:17, 26 March 2014 (UTC)<br />
:The unknown information is the sample size (class size, for example) and standard distribution (by how much, on average, is something going to vary from the mean). The unknown information is not "in the data".[[User:Jarod997|Jarod997]] ([[User talk:Jarod997|talk]]) 12:28, 26 March 2014 (UTC)<br />
:Basically, if you have an underlying process that would produce samples with a Gaussian distribution with mean of 0, and stddev of 1, and then you pull a finite number of samples out of it, and do the usual "average" operation on those samples (i.e. sum them and divide by the number of samples) you would expect that that computed average would be close to zero. But it might not be! By chance the samples you pulled might mostly have been from the far right or left side of distribution and the average you got would be way off. Student's T distribution (for a certain number of samples, n) is basically "given that the underlying process a Gaussian with mean zero and stddev of 1, if I repeatedly take n samples from that distribution and compute the average of those samples to get an "estimated mean", this is how I expect that estimated mean to be distributed". Naturally, this is important in questions like "I took 100 samples and got an average of 0.02 -- does this mean that it is sensible to think that the mean of the underlying distribution is actually zero?" <br />
: Of course, most of the joke is that the distribution is named "Student's", which is not strongly dependent on the nature of the statistics. [[User:Vyzen|Vyzen]] ([[User talk:Vyzen|talk]]) 12:42, 26 March 2014 (UTC)<br />
::Okay, it's pretty clear to me now what the Student's t distribution is. I'm still not sure about the punchline though, how does the "Teacher's" t distribution come into play? Does the uneven distribution represent any phenomena in the academic world? Like, as suggested above, is this a joke about grading?

I took from it that the Students Distribution was too perfect, and real data would rarely yield those idealized results in a small sample size. That the teacher's distribution used actual numbers, with the occasional spikes. I took from the title text, the tendency of students, or anyone with pre-conceived notions, to keep redoing the test until they get the results they expect, in this case, the textbook result.

<br />
:I don't think he he trying to pull the paper from out beneath the t-distribution. I think he is placing the distribution on top of the paper to see if the data on the paper matches the distribution. In panel 2, he looks at the paper and decides that, no, it doesn't, so then opts to use another distribution - the Teacher's t-distribution and see if that works.

Question: If there are 24 Hours in a day, why in the description does it go from hour 0 to hour 21? That's only 22 hours. Where are the other 2 hours? Even if it isn't listed on the comic (I think it's the time zones in the Atlantic between Eastern Brazil and the UK - basically UTC-1hr and UTC-2hr), shouldn't there be spaces in the charts showing those hours? I don't think any of the islands in that region use those time zones (opting instead to use GMT - like Iceland for example), but I think those hours should still be included since they ''are'' on the static part of the map. Also, it makes sense to me that the center of the words ''NOON'' and ''MIDNIGHT'' are edges of segments themselves, making 24 segments in total. Randall just couldn't draw those discrete segments and also easily have the words written for our convenience. --[[User:Dangerkeith3000|Dangerkeith3000]] ([[User talk:Dangerkeith3000|talk]]) 16:46, 26 February 2014 (UTC)</div>Dangerkeith3000https://www.explainxkcd.com/wiki/index.php?title=Talk:1335:_Now&diff=61140Talk:1335: Now2014-02-26T17:00:50Z<p>Dangerkeith3000: </p>

==Explanation==<br />
{{incomplete|Why the empty space around Earth? Also, it does not display the currenty known exoplanets because we do know any.}}<br />
The diagram is a graphic representation of all of the currently known exoplanets (planets not in our solar system) within 60 light years of Earth which lie in a {{w|Circumstellar habitable zone|habitable zone}}; that is, a planet whose orbit is within a certain range of distance from a star such that water could exist in a liquid state. They are categorized in two ways. By color: a reddish tone denotes planets orbiting stars similar in characterstics to our sun, while grey indicates those that don't; and by size, with planets similar to Earth's size depicted in a slightly darker shade of either color. The diameter of each circle shows the relative size of the planet with respect to the size of the earth (pictured in the center).<br />
<br />
The aparent conclusion is that there are a significant number of Earth-sized planets orbiting Sun-type stars which could be habitable (and even more possibly-habitable planets around other types of stars or in other sizes).<br />
<br />
The title of the comic "It's a beautiful day in the neighborhood!" is an allusion to the former PBS television show [https://en.wikipedia.org/wiki/Mister_Rogers'_Neighborhood "Mister Rogers' Neighborhood"] in which the same line presents itself in the opening song, [https://en.wikipedia.org/wiki/Mister_Rogers'_Neighborhood#Regular_songs "Won't You Be My Neighbor?"].<br />
<br />
The title text is a link to a larger version of the comic, found [http://xkcd.com/1298/large/ here].<br />

For those of us who do not live in one of these four cities, does anyone have a more comprehensive set of data for the rest of the continent? Or specifically NYC? ;)<br />
<br />
Striations on the rocks in Central Park are evidence that a glacier did reach as far south as New York City and in the referenced article on page 21, Figure 4 shows a map of the extent of the glacier just reaching NYC and Long Island and is labeled as somewhere between 0 and 600 meters thick. This page on the City of New York Parks and Recreation site [http://www.nycgovparks.org/about/history/geology] says the glacier in NYC was about 1000 feet thick which is about 300 meters. I should add that the Freedom Tower being built on the WTC site will be 1776 feet high (counting the broadcast antenna) and the Empire State building is 1454 feet high, so some of the current buildings would have poked out of the ice.<br />

:I don't think so, just because someone finds it amazing how deep the ice during the last glaciation was, doesn't imply anything about their opinion on the causes of changes in climate over the few centuries. By the way, the glaciers have {{w|Timeline_of_glaciation|melted and refrozen lots of times}}, they haven't always been melting.[[User:NHSavage|NHSavage]] ([[User talk:NHSavage|talk]]) 18:44, 14 June 2013 (UTC)<br />
<br />
==Global Warming==<br />
The actual climate discussion is still not solved. But we do know very well that the ocean sea level was 130 Meters lower than today at that time. At the end of that period the sea level was growing fast, but then it did raise slower later, and that raise didn't stop until today. Randall is only showing ICE levels, not more.--[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 22:17, 14 June 2013 (UTC)<br />
<br />
<br />
I've read and re-read both comic and explanation (and, moreover, the above comments) and I just can't agree with the current third and final paragraph of the explanation ("But the joke ... (see Sea level rise)."). It is, to my mind, merely ''interesting'' that at a time of ice-age there was far more depth of ice pressing down upon sites than there currently are famous heights of buildings above the present day, and ice-less, horizons at these particular locales, as depicted. The sole joke, to my mind, is in the title-text, with the direct swapping of the common Ice Age film series's prefix for the souce paper's title. (Which is jolly funny!) And is in line with some of Randall's other largely "informative" strips, jokes sneaking in only as captions and labels.<br />
<br />
It is indeed also interesting to note, as a side-issue, that glaciation (and thus deglaciation) relates somewhat to sea level (but note also {{w|Post-glacial rebound}} as a significant effect in some areas, both reinforcing ''and'' opposing sea-level changes, depending on locale). However, there's not even any mention of relative sea-level in the images. This ''could'' perhaps have been implemented as an arrow tacked onto the side of each depth-extended cross-section, pointing base to point (or vice-versa) between the axial position of the historic Mean Sea Level (if known) and that relating to the current state of affairs, in perfect scale against the column of sky-line and ice. But right now there's no reference at all to support this thought, and thus hardly asks for any such 'explanation' or reference. (There's similarly no invocation of the "climate discussion", unsolved or otherwise, outside of our combined commentary on the comic.)<br />
<br />
Mayhap are people being confused by the (admitedly) water-like appearance of the depiction of ice-layer? Possibly thinking that these diagrams are of ''submerged'' cities (''a la'' representations in various /The Day After Tomorrow/, /A.I. Artificial Intelligence/ or /2012/-ish films), not ones figuratively transplanted back back into the ancient ice-mass... Or are people inadvertently trolling their personal pro/anti-Climate Change views here (esp. w.r.t. Human impact)? Perhaps subconciously reading more (potentially pro- ''or'' anti-!) into the comic than (so far as I can see) was ever intended. If you'll forgive my hopefully 'neutralist' stance on the issue (i.e. divorced of my semi-moderate stance on the issue, which is in whatever direction it is that I lean... but which I have deliberately tried to have kept unstated).<br />
<br />
Add to this that Randall shows only Leftpondian locations (and upper-Leftpondian ones, at that, due to the specialised scope of the source paper) this also makes me wonder why Europe and Asia are mentioned in that para, (unless it's meant to say "Ice Ages didn't just happen to North American, but also to similar latitudes in a circumpolar fashion", in which case could we also add anything we know about the southern hemisphere as well?). But that's a minor niggle I have in a paragraph that (obviously, from the length I've been taking pains to discuss all this within) I just can't get a handle on in the first place. But perhaps I'm missing something so, rather than editing and excising the main article, here I ramble on about it. Perhaps to pursuade some prior contributor to re-explain their particular contributions. (We now return you to your regularly scheduled programme...)

:Well ''maybe'' that's {{w|Boston, Lincolnshire}} or {{w|Montreal, Catalonia}}. Or even the respective ones in the Philippines/Jordan. But I still doubt it. ;) Anyway, as per the TL;DR; mess of my prior comment 'contribution' I still don't like that ending. But that could just be me misreading.

:Examine the transcript and Cueball's movement in the second and third panel. The time machine in this comic is a time-reversing one, not a time jumping one.

<br />
My thoguhts:<br />
Cueball turns on the time machine, which starts up and they start going back in time, returning to the time the machine it turned on. Time is going in perfect reverse, so the machine switches off and then he is back where he started. [[Special:Contributions/216.81.49.162|216.81.49.162]] 05:10, 24 April 2013 (UTC)<br />
<br />
I didn't get it when I first read it, and this explanation seems to make the most sense; if it is the intended joke, I wish Randall would have reversed the sound effect "click" in the third panel ("!kcilC"), which would indicate that time is moving backwards (from the reference frame we're watching it from), which would have made this explanation more obvious for me.[[Special:Contributions/64.20.186.2|64.20.186.2]] 18:22, 24 April 2013 (UTC)larK<br />
<br />
<br />
The Machine even turns back Cueballs actions, so maybe even his memory of turning it on, what might make him so puzzled - eventually - if he decides rational to try the machine (and if desicdes always rational) - he will get in a loop of turning it on - travelling back and forgetting that event - and turning it on again. - That might get Interesting [[Special:Contributions/212.202.64.10|212.202.64.10]] 05:32, 24 April 2013 (UTC) Lupo<br />
<br />
I don't think he looks puzzled because nothing happened, I think he's curious b/c he just came across a Time Machine. That is, the last frame of the strip takes place seconds before the first. So the "trouble" with time machines (of this variety) is that if you go back in time you can't take the present with you, and nothing changes.<br />
[[Special:Contributions/76.95.49.45|76.95.49.45]] 06:00, 24 April 2013 (UTC)<br />
<br />
Alternative view: Feedback. Stephen Hawking has discussed the general problem with a whole class of time machines (namely, wormwhole based time machines), where the energy from the future is added exponentially to the system due to system feedback. More or less as a microphone cannot get too close to its speaker without having that horrible sound. This would explain who the guy in the comic turns the machine off... there is a large buildup of energy feedback and this can be observed in the EEEEE...<br />
<br />
"In the end, I think a wormhole like this one can't exist. And the reason for that is feedback. If you've ever been to a rock gig, you'll probably recognise this screeching noise. It's feedback. What causes it is simple. Sound enters the microphone. It's transmitted along the wires, made louder by the amplifier, and comes out at the speakers. But if too much of the sound from the speakers goes back into the mic it goes around and around in a loop getting louder each time. If no one stops it, feedback can destroy the sound system.<br />
The same thing will happen with a wormhole, only with radiation instead of sound. As soon as the wormhole expands, natural radiation will enter it, and end up in a loop. The feedback will become so strong it destroys the wormhole. So although tiny wormholes do exist, and it may be possible to inflate one some day, it won't last long enough to be of use as a time machine. That's the real reason no one could come back in time to my party.<br />
<br />

<br />
But with that above analogy, in a sound system, you have external power to amplify the signal - the energy the microphone takes out is not what gets put back out. In a wormhole, unless there is something to amplify the radiation that comes out the other end then it's a closed system (and if you do amplify it then where did THAT energy come from).

<br />
Another problem with this design of a time machine is that it draws power from the wall. What would happen if he crosses the time when there was no outlet at that location? Or no power grid at all? But that may not pose a problem here because it seems he doesn't get too far back into the past anyway. So, for our future time machine inventors: make those machines self-contained! --[[Special:Contributions/216.165.95.66|216.165.95.66]] 15:24, 24 April 2013 (UTC)<br />
<br />
:I think that pretty much somes up why some people think you can't use a time machine to go back in time before the time machine ''itself'' existed. If it was an ancient time machine, you could go back quite far, but if one was made on February 5, 2013 you couldn't travel before that point because the time machine wouldn't exist before that time, so no time machine anymore, no travel. Hence what you said about crossing the time when there was no outlet.

Ugh! The original explanation (going back in time by one second) is drastically over thought. It's a "time machine" that does nothing other than make a noise -- just a box with a switch. Cueball turns it on, and a second later turns it off, thus having traveled through time into the future by one second. The T numbers are incrementing, just as they always do, even prior to a rocket launch. We're all traveling through time -- "all systems ARE normal." Please reconsider.

: Except that he is travelling into the *past* by one second. He goes from T-10 to T-11 - that's back in time. I think the original explanation is on the button. As soon as he starts to go back in time, he undoes the action of activating the machine, so he doesn't get anywhere. [[User:MGK|MGK]] ([[User talk:MGK|talk]]) 23:46, 24 April 2013 (UTC)<br />

Cueball turns on the time machine, which starts up and they start going back in time, returning to the time the machine it turned on. Time is going in perfect reverse, so the machine switches off and then he is back where he started. [[Special:Contributions/216.81.49.162|216.81.49.162]] 05:10, 24 April 2013 (UTC)<br />

I didn't get it when I first read it, and this explanation seems to make the most sense; if it is the intended joke, I wish Randall would have reversed the sound effect "click" in the third panel ("!kcilC"), which would indicate that time is moving backwards (from the reference frame we're watching it from), which would have made this explanation more obvious for me.[[Special:Contributions/64.20.186.2|64.20.186.2]] 18:22, 24 April 2013 (UTC)larK<br />

The Machine even turns back Cueballs actions, so maybe even his memory of turning it on, what might make him so puzzled - eventually - if he decides rational to try the machine (and if desicdes always rational) - he will get in a loop of turning it on - travelling back and forgetting that event - and turning it on again. - That might get Interesting [[Special:Contributions/212.202.64.10|212.202.64.10]] 05:32, 24 April 2013 (UTC) Lupo<br />

I don't think he looks puzzled because nothing happened, I think he's curious b/c he just came across a Time Machine. That is, the last frame of the strip takes place seconds before the first. So the "trouble" with time machines (of this variety) is that if you go back in time you can't take the present with you, and nothing changes.<br />

Alternative view: Feedback. Stephen Hawking has discussed the general problem with a whole class of time machines (namely, wormwhole based time machines), where the energy from the future is added exponentially to the system due to system feedback. More or less as a microphone cannot get too close to its speaker without having that horrible sound. This would explain who the guy in the comic turns the machine off... there is a large buildup of energy feedback and this can be observed in the EEEEE...<br />
<br />
"In the end, I think a wormhole like this one can't exist. And the reason for that is feedback. If you've ever been to a rock gig, you'll probably recognise this screeching noise. It's feedback. What causes it is simple. Sound enters the microphone. It's transmitted along the wires, made louder by the amplifier, and comes out at the speakers. But if too much of the sound from the speakers goes back into the mic it goes around and around in a loop getting louder each time. If no one stops it, feedback can destroy the sound system.<br />
The same thing will happen with a wormhole, only with radiation instead of sound. As soon as the wormhole expands, natural radiation will enter it, and end up in a loop. The feedback will become so strong it destroys the wormhole. So although tiny wormholes do exist, and it may be possible to inflate one some day, it won't last long enough to be of use as a time machine. That's the real reason no one could come back in time to my party.<br />

<br />
But with that above analogy, in a sound system, you have external power to amplify the signal - the energy the microphone takes out is not what gets put back out. In a wormhole, unless there is something to amplify the radiation that comes out the other end then it's a closed system (and if you do amplify it then where did THAT energy come from).

<br />
Another problem with this design of a time machine is that it draws power from the wall. What would happen if he crosses the time when there was no outlet at that location? Or no power grid at all? But that may not pose a problem here because it seems he doesn't get too far back into the past anyway. So, for our future time machine inventors: make those machines self-contained! --[[Special:Contributions/216.165.95.66|216.165.95.66]] 15:24, 24 April 2013 (UTC)<br />

:I think that pretty much somes up why some people think you can't use a time machine to go back in time before the time machine ''itself'' existed. If it was an ancient time machine, you could go back quite far, but if one was made on February 5, 2013 you couldn't travel before that point because the time machine wouldn't exist before that time, so no time machine anymore, no travel. Hence what you said about crossing the time when there was no outlet.

== We're all trawling into the future, just like Cueball ==<br />
<br />
Ugh! The original explanation (going back in time by one second) is drastically over thought. It's a "time machine" that does nothing other than make a noise -- just a box with a switch. Cueball turns it on, and a second later turns it off, thus having traveled through time into the future by one second. The T numbers are incrementing, just as they always do, even prior to a rocket launch. We're all traveling through time -- "all systems ARE normal." Please reconsider. Jeff.<br />
<br />
um... no. it's called "countdown" for a reason.[[Special:Contributions/212.186.64.47|212.186.64.47]] 17:47, 24 April 2013 (UTC)<br />

: I agree with [[Special:Contributions/212.186.64.47|212.186.64.47]], I also think Cueball moved 1 second into the future, much like [[630: Time Travel]] [[User:Saibot84|Saibot84]] ([[User talk:Saibot84|talk]]) 19:12, 24 April 2013 (UTC)<br />

Cueball turns on the time machine, which starts up and they start going back in time, returning to the time the machine it turned on. Time is going in perfect reverse, so the machine switches off and then he is back where he started. [[Special:Contributions/216.81.49.162|216.81.49.162]] 05:10, 24 April 2013 (UTC)<br />

<br />
The Machine even turns back Cueballs actions, so maybe even his memory of turning it on, what might make him so puzzled - eventually - if he decides rational to try the machine (and if desicdes always rational) - he will get in a loop of turning it on - travelling back and forgetting that event - and turning it on again. - That might get Interesting [[Special:Contributions/212.202.64.10|212.202.64.10]] 05:32, 24 April 2013 (UTC) Lupo<br />

I don't think he looks puzzled because nothing happened, I think he's curious b/c he just came across a Time Machine. That is, the last frame of the strip takes place seconds before the first. So the "trouble" with time machines (of this variety) is that if you go back in time you can't take the present with you, and nothing changes.<br />

Alternative view: Feedback. Stephen Hawking has discussed the general problem with a whole class of time machines (namely, wormwhole based time machines), where the energy from the future is added exponentially to the system due to system feedback. More or less as a microphone cannot get too close to its speaker without having that horrible sound. This would explain who the guy in the comic turns the machine off... there is a large buildup of energy feedback and this can be observed in the EEEEE...<br />
<br />
"In the end, I think a wormhole like this one can't exist. And the reason for that is feedback. If you've ever been to a rock gig, you'll probably recognise this screeching noise. It's feedback. What causes it is simple. Sound enters the microphone. It's transmitted along the wires, made louder by the amplifier, and comes out at the speakers. But if too much of the sound from the speakers goes back into the mic it goes around and around in a loop getting louder each time. If no one stops it, feedback can destroy the sound system.<br />
The same thing will happen with a wormhole, only with radiation instead of sound. As soon as the wormhole expands, natural radiation will enter it, and end up in a loop. The feedback will become so strong it destroys the wormhole. So although tiny wormholes do exist, and it may be possible to inflate one some day, it won't last long enough to be of use as a time machine. That's the real reason no one could come back in time to my party.<br />

<br />
But with that above analogy, in a sound system, you have external power to amplify the signal - the energy the microphone takes out is not what gets put back out. In a wormhole, unless there is something to amplify the radiation that comes out the other end then it's a closed system (and if you do amplify it then where did THAT energy come from).

Another problem with this design of a time machine is that it draws power from the wall. What would happen if he crosses the time when there was no outlet at that location? Or no power grid at all? But that may not pose a problem here because it seems he doesn't get too far back into the past anyway.

If it was an ancient time machine, you could go back quite far, but if one was made on February 5, 2013 you couldn't travel before that point because the time machine wouldn't exist before that time, so no time machine anymore, no travel.

Not the full explanation?But what exactly is the joke here?It takes a lot of practice to be able to do integration sums correctly.[[User:Guru-45|Guru-45]] ([[User talk:Guru-45|talk]]) 05:26, 19 April 2013 (UTC)<br />
<br />
I think the joke is rather “which definitely looks easier” — that’s how mathematics is generally perceived by non-mathematicians: You rewrite something, state that it looks easier / more beautiful / more elegant — which the non-mathematician usually perceives differently — and even if it does, you’re not a tad nearer to the answer. --[[Special:Contributions/84.191.162.248|84.191.162.248]] 08:00, 19 April 2013 (UTC)<br />
<br />
Symbolic integration ALWAYS require experience and trial-and-error, which is flustrating given that the reverse process - derivation - can be described with simple alghorithm and done mechanically. I heart that derivation is easy as geting toothpaste out of tube and integration is reverse process ... meaning its as hard as puting the toothpaste back into tube. The reason is that there is simple rule for derivation of product, whereas integration of product is usually done by GUESSING the product which will derivate into given integral (which is what integration by parts actually is, only reformulated to sound little easier). -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 09:18, 19 April 2013 (UTC)<br />
<br />
: By using the term ''derivation'', you mean it as the same as the term ''differentiation'', correct? I've never used the term derivation before. I like it, it's shorter. If so, YES, integration of products is WAY harder. 'u' substitutions alone are a pain - having a 'v' substitution as well requires a lot of hard work and trial and error...<br />
<br />
''Oh, and add a '+C' or you'll get yelled at.''<br />
Best part. This is something I experienced many times in my first semester of mathematics for scientists. <br />
The joke seems to me to be the presentation of the idea accurately; after the initial step, there's no real advice to give. Good luck is the best you can hope for.

One can make assuptions about the age of those in the first group because of the shape of the beverage vessels. A wine or champagne glass might be used for it's name sake. Suggesting that they are older than the legal drinking age. Though the conversation seems like one expected in high school or college.{{unsigned|74.215.40.250}}<br />

200 million times .01% (or the remainder of germs that would be left after using the hand sanitizer; .01% is equivalent to .0001 decimal, so the simple equation is 200000000 x .0001. That equals 20 thousand germs, which is still a surprisingly large number of germs.<br />

Do E. coli bacteria mask the response of Staphylococcus? Do the responses go through the gift wrapping? The gift from the guy should have shown Gram-positive, because of Staphylococcus. Thus the mistake. --[[Special:Contributions/79.201.88.62|79.201.88.62]] 13:08, 25 December 2012 (UTC)<br />

Of course, the dye used in Gram-staining is DYE and will color hands, clothing, (wrapping) paper, and floors. Megan might not have a bunch of bacteria coated presents (except for the one from That Guy in the title text), and instead she has just ruined her own Christmas.

[[Randall]]'s Wikipeida path: {{w|Virus}} -> {{w|Immune system}} -> {{w|Innate immune system}} -> {{w|Parasites}} -> {{w|List of parasites of humans}} -> {{w|Naegleria fowleri}} -> {{w|Primary amoebic meningoencephalitis}}.<br />
<br />
Naegleria fowleri is supposedly also known as the brain-eating amoeba. It is found in warm bodies of stagnant {{w|fresh water}} (like in an aquarium?) and causes the disease primary amoebic meningoencephalitis, a rare but highly lethal condition. (Randall also seems to be too sick to spell {{w|Wikipedia}}.)<br />

<div>This was one of the reasons early Christians were persecuted by the Romans. They thought the Christians were cannibals. [[Special:Contributions/76.20.159.250|76.20.159.250]] 00:53, 27 December 2012 (UTC)<br />

Isn't he making fun of that doctrine?[[User:Guru-45|Guru-45]] ([[User talk:Guru-45|talk]]) 07:16, 27 December 2012 (UTC)<br />
<br />
Transubstantiation isn't about bread literally turning into flesh. I don't know how to explain it properly, but it is based on Middle Age Christian philosophy (scholastic, St. Thomas, I think) that differentiates the accidents (appearance, taste etc.) of a thing from its true substance. Transubstantiation means that the bread becomes flesh (acquires the substance of Jesus' flesh) even though it retains the appearance and all qualities of bread.<br />
This doctrine is of course highly outdated and I can't think of why the Catholics haven't dropped it yet. It also causes a lot of confusion. --[[User:Artod|Artod]] ([[User talk:Artod|talk]]) 09:07, 27 December 2012 (UTC)<br />
<br />
:If it's middle age Christian, what was the explanation before that? -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 09:20, 27 December 2012 (UTC)<br />
<br />
::I would think that the original interpretation is symbolism. Jesus and his diciples were eating the {{w|passover}} meal, and the central piece was a {{w|Korban Pesach|sacrifical lamb}}. I think that it's a way for Jesus to say that the purpouse of the lamb is becoming dated, cause I'm about to be murdered, and that is what will save you in the end, not sacrifices. From start christians have called him the {{w|Lamb of God}}. Hope you had a merry Christmas! -- [[User:St.nerol|St.nerol]] ([[User talk:St.nerol|talk]]) 10:14, 27 December 2012 (UTC)<br />
