==Explanation==
{{incomplete| Title text - is that also a Hillary slogan?}}
In this serious comic released the day before the {{w|2016 United States presidential election}}, [[Randall]] urges his American viewership to vote, and states that he supports (and votes) for {{w|Hillary Clinton}}, the {{w|US Democratic Party|Democratic}} nominee in the election who is up against the {{w|US Republican Party|Republican}} nominee {{w|Donald Trump}}. (The rest of his viewers from abroad can spread the word by sharing this comic online.)

The "H" with an arrow is Clinton's campaign logo, and '''I'm with her''' is a slogan widely used by her supporters, and thus explains the title and the caption below the H. Randall then lists tips to help you cast your vote, [[#How to help|see table below]]. This suggests he is invested in the election. Clinton herself may be represented by [[Blondie]] sitting on top of the H looking out at the reader as the only of the 11 characters (see [[#Character gallery|character gallery]] below).

All the information on the bottom half of the comic includes sites, numbers, info, etc that will help US voters to vote, regardless of for whom they will vote for. Including this information helps voters because every election many voters don't vote because they feel they don't know how or that it isn't worth it. It seems like Randall doesn't want the US election to have some of the same problems that the {{w|Brexit}} vote had (where many voters opposed to exiting the EU didn't vote for one reason or another).

The title text states that "We can do this" refers to Randall's wish that the democratic voters united can put Hillary in the White House rather than Trump.

==How to help==
Randall lists four suggestion for how to help Hillary Clinton winning the election:

==Character gallery==
The comic show a gallery of 11 xkcd characters including all the main characters from xkcd (except [[Hairy]]), which stand united behind Randall and Clinton despite their lack of agreement in many other comics.

*From left to right on the left side of the H are:
**[[Ponytail]] with a ray gun for melting computers, (the one she also wielded in [[322: Pix Plz]], a comic where she was named Joanna)
**[[Black Hat]] (who was the one introducing Joanna/Ponytail in the mentioned comic)
**[[Danish]] (Black Hat's girlfriend setting up a kite for him, although it could be Megan, but she is also shown later with her regular shorter hair). However it has mainly been Megan in comics with kites, like [[235: Kite]] and [[1614: Kites]. Kites are a [:Category:Kites|recurring theme]] on xkcd.
**[[White Hat]] looking at the kite.
*On top of the H are:
**[[Blondie]] (looking out at us, maybe representing Clinton herself)
**[[Megan]] (next to Cueball)
**[[Cueball]] (forming the standard couple in xkcd with Megan)
**[[Hairbun]] with glasses (so specifically not the one from the previous comic [[1755: Old Days]], but rather like in [[1637: Salt Mine]]).
*On the right side of the H are:
**The adult version of [[Science Girl]] (She is holding her hand out towards a cute squirrel. Of course she could also be the girl from [[635: Locke and Demosthenes]] where the squirrel is poisoned...)
**[[Beret Guy]] is holding a squirrel out towards Science Girl. (The first time squirrels was mentioned was actually when Beret Guy found them in a tree in [[167: Nihilism]] and since then they have become a [:Category:Squirrels|recurring theme]] on xkcd and a similar squirrel can for instance be seen in [[1503: Squirrel Plan]]. Beret Guy has not been seen together with a squirrel before, but has been shown to care for animals, for instance in [[614: Woodpecker]]).
**Finally [[:Category:Multiple Cueballs|another Cueball]] standing on an office chair wielding a sword as he was shown in [[303: Compiling]]. (Interestingly enough the previous comic [[1755: Old Days]] was about Cueball asking Hairbun about {{w|compiling}} in the old days. Seems realistic that Randall has this comic ready for this Monday before the election for some time, and when finding this 9 year old version of Cueball in the old comics, he may have gotten inspired to make a comic about compiling in the old days).

Note that the two characters at either side of the comic wields weapons pointing out defending the other nine. Those next to the characters with weapons are doing recreational things like kiting and admiring adorable squirrels, both are recurring subjects in xkcd.

==Transcript==
:[Eleven characters are drawn left, right and on top of a huge H with an arrow as the horizontal bar connecting the two vertical towers. The arrow breaks the right part of the H. It represents the logo from Hillary Clinton's presidential campaign for 2016. From left to right on the left side of the H are Ponytail with an exotic looking futuristic ray gun like weapon looking to the left away from the H and the others. Behind her is Black Hat who looks at a girl that might be Danish or Megan (but with longer hair than Megan typically has). She is setting up a kite that flies above the first two characters. Behind her and looking up at the kite is White Hat. The H is right behind him, and on top of the left tower of the H sits Blondie looking straight out at the reader with her legs dangling over the edge and her arms resting on her knees. On the arrow between the two H towers sits Megan leaning against the left H tower, also dangling her legs over the edge and arms resting on her knees. Cueball is standing to her right, just left of the right H tower. On top of the right H towers sits Hairbun with glasses looking straight right with her legs dangling over the edge one arm resting on a knee and leaning back on the other arm. On the right side of the H is an adult version of Science Girl holding a hand out towards the squirrel which Beret Guy is holding out in both arms towards her. Behind them is another Cueball standing on an office chair holding a sword high up in front of him to the right away from the others. He keeps his balance by holding his other arm out behind him. Below the H there is a large caption.]

108.162.215.183:

This is another one of Randall's knocks on pseudoscience... I've seen things like this before, where the guy puts 1000's of volts between a piece of tinfoil and a wire and is amazed that the thing (weighing a few grams) flies around. I'd search for it for reference but it's late here and I'm tired [[Special:Contributions/173.245.54.209|173.245.54.209]] 04:41, 6 August 2014 (UTC)

20 kW is probably not from any reference, but just to summarize the history of claims in a vivid manner. The news surge was predicated about the prestige of the NASA organization attaching to any tiny lab under the aegis even though the paper was not in a peer-reviewed top journal but the very last presentation made at a multi-day conference. The NASA abstract differs wildly from the abstract of the same-date paper (or draft). http://rghost.net/57230791 \\ Other coverage from the skeptical side goes a bit into the history of similar microwaves-in-a-funny-shaped-can claims, where the reported thrust seems to diminish as the sensitivity of the measurement. http://scienceblogs.com/principles/2014/08/04/impossible-thruster-probably-impossible/ http://blogs.scienceforums.net/swansont/archives/15155 https://plus.google.com/117663015413546257905/posts/WfFtJ8bYVya https://plus.google.com/117663015413546257905/posts/C7vx2G85kr4 And finally may I close with a reference to Tooth-Fairy-(pseudo)science. http://www.skepdic.com/toothfairyscience.html [[Special:Contributions/199.27.128.118|199.27.128.118]] 05:41, 6 August 2014 (UTC)

What I'm missing is any reference to NASA being the third party to conduct this experiment and the third to witness these results. So while this looks an awful lot like Tooth-Fairy-science, it still raises the question of what the hell is going on there? Usually these pseudo-science experiments fail on reproduction or are only reproduced by non-scientists. - Nine [[Special:Contributions/141.101.104.59|141.101.104.59]] 06:46, 6 August 2014 (UTC)

;Fancy way of building an (ordinary) photon drive

A bit of context:

The idea of using virtual particles/quantum foam as your reaction mass has been around for a while. This turns out to just be an overly-complicated way of building a photon drive. If you accelerate a charge (real or virtual), it'll spit out photons. If you interact with charged virtual particles in a way that results in real thrust (by accelerating them), the photons you get out are real photons, and you pay for them in the usual manner (they cost you energy).

If you're building a photon drive, a heating element and a mirror work just as well.

As for the anomalous thrust in the experiments, there are a huge number of ways that you can get that from an experiment that isn't set up sufficiently carefully. The fact that two different experiments got vastly different measurements is a very big hint that something was flawed with at least one of them (possibly both).

Among other things, generating intense microwaves involves large electric currents. If any part of your apparatus is made of metal (and lots of this was), ordinary EM forces produce quite a few contaminating effects that are a royal pain to account for, especially if you're trying to measure an effect much weaker than they are. --[[Special:Contributions/108.162.246.221|108.162.246.221]] 09:26, 6 August 2014 (UTC)

I don't like how the sciencey posts use a lot of scientific terms without explaining them. I thought the purpose of this site was to make xkcd accessible for all people, science laymen included, but sometimes these explanations obfuscate more than they help. --[[Special:Contributions/141.101.99.188|141.101.99.188]] 10:46, 6 August 2014 (UTC)

I don't see any "joke on quantum superposition". Either explain what the jokes are or remove that claim? --[[Special:Contributions/141.101.98.162|141.101.98.162]] 12:08, 6 August 2014 (UTC)
: That was a "correction" of "quantum supposition" which made more sense. Chad Orzel makes an ''actual'' joke about quantum superposition: "Most physicists I know have reacted to this with some linear combination of “heavy sigh” and “eye roll.”" Anyway, I have edited away the superposition by rewriting the description of the last panel. [[Special:Contributions/199.27.128.118|199.27.128.118]] 16:02, 6 August 2014 (UTC)
:: I don't see any joke about quantum uncertainty, just regular uncertainty and the scientific method in the last panel. The claim of thrust without exhaust or other momentum transfer is a claim of new physics, but the evidence of this claim is weak because the device was not tested in isolation and vacuum and the reported thrust was not in line with the claimed mechanisms. But Megan points out that new physics isn't created but only discovered, so she is just as likely to interact with the newly claimed physics as the Q-drive if enough power is applied. The Uncertainty Principle applies to systems not what model of physics applies so the claims of the Q-drive mechanism can't be in a superposition of true and false.

;Not "a violation of conservation of momentum"

Please can someone senior in this community update this as I don't want to get I to an edit war. Unfortunately the media has been conflating the idea between the [[http://en.wikipedia.org/wiki/EmDrive |EmDrive]] and a [[http://en.wikipedia.org/wiki/Quantum_vacuum_plasma_thruster |Quantum vacuum plasma thruster]] as Roger Shawyer has been talking about both. NASA tested the idea of a Quantum vacuum plasma thruster which does not violate conservation of momentum

--[[Special:Contributions/173.245.56.213|173.245.56.213]] 15:06, 6 August 2014 (UTC)

: NASA did not test "the idea of a Quantum vacuum plasma thruster" -- In 2013, a very small group of researchers at NASA tested a pair of RF devices supplied to them for 2 days (and 6 days of setting up the tests). One was supposed to produce thrust in empty space while the other wasn't. But both devices were tested in air and very similar results recorded for both. Therefore either the test was flawed or the devices did not operate sufficiently different from each other to measure. Thus the "idea" was not tested, only the supplied devices and the testing protocol. In that the devices were allegedly designed to demonstrate designs to take advantage/not take advantage of the so-called "quantum vacuum virtual plasma," then to the extent where NASA might have tested a new physics principle, they certainly did not validate it. They also tested (in 2014) a much different Shawyer-type microwaves-in-a-can RF load, and got similar results. The details of the testing (and a misleading section on the vacuum capabilities of the chamber and a weird part on interplanetary trajectories) are in the pre-print.

: But as for conservation of momentum, the principle claim is that the "Quantum vacuum plasma thruster" imparts momentum on the microwave cavity while balancing opposite momentum goes where? Since the vacuum has no state of motion and no momentum, not here. Since no microwaves or other particles are emitted, not here. Thus the claim violates conservation of momentum. [[Special:Contributions/199.27.128.118|199.27.128.118]] 15:55, 6 August 2014 (UTC)

:After reading both [http://en.wikipedia.org/wiki/Quantum_vacuum_plasma_thruster Quantum vacuum plasma thruster] and [http://en.wikipedia.org/wiki/EmDrive EmDrive], it seems that they're the same type of device. In particular, scroll down near the bottom of the EmDrive article, and you can see that they're using "interacting with virtual particles" as one of the justifications for it working. Both articles also cite several of the same experiments in their introductions. The physical description of both devices was similar (resonant microwave cavities), differing only in specific cavity geometry.

:And yes, they would have had to be tested in vacuum for a serious test. If you have strong electric fields in air, the air will move (because you'll bleed charge into it, and it'll then be accelerated by the electric field; that's how those tinfoil "lifter" devices work). You'd also have to put it in an RF-absorbing chamber, to avoid resonant interactions with the chamber walls (which can cause your device to be displaced from what you think its neutral position should be; force only costs power while you're moving, so this would look like deflection with no net power applied after the system stabilizes). -[[Special:Contributions/108.162.246.221|108.162.246.221]] 20:17, 6 August 2014 (UTC)

; Revision weirdness

(For [[User:Dgbrt|Dgbrt]]) Not meaning to start an edit war, but how is [http://nasawatch.com/archives/2014/08/jscs-stealthy-s.html NASAWatch] a better source for the breaking news than the earlier and glossier [http://www.wired.co.uk/news/archive/2014-07/31/nasa-validates-impossible-space-drive Wired UK]. Also, Johnson Space Center and NASA are under no obligation to comment on the work of the Eagleworks lab under Sonny White. That's just one of the many points that Hambling and NASAWatch get wrong: "NASA" didn't validate anything, a small group of researchers employed by NASA claimed verification in a non-peer-reviewed presentation at a conference. [[Special:Contributions/199.27.128.99|199.27.128.99]] 20:20, 8 August 2014 (UTC)
:First thanks for not doing an edit war. My reasons were:
:*NASAWatch is still the most serious site to document but also criticise NASA's activities.
:*The "wired.co.uk" article is available at that NASAWatch article. I decided to remove that "wired" link here because it uses a hell of external sites blocked at my browser by default (NoScript on Firefox). The site is not "wired.com", one of my favorite pages is there: [http://www.wired.com/category/beyondapollo/ Beyond Apollo].
:*NASA did NOT release any official statements, only a small external publication did refer to an NASA employer.
:*NASA keeps silent on this matter because they know there is no prove.

: "'NASA' didn't validate anything, a small group of researchers employed by NASA claimed verification" -- This is (a) needlessly splitting hairs and (b) incorrect. When an organization employs individuals to take actions, those actions are, ''de facto,'' the actions of the organization. If the researchers were employed by NASA to verify or validate a claim, and they did so successfully, then it is said that NASA verified or validated the claim. The only way your assertion would be true is if the researchers, which ''just happened'' to be otherwise employed by NASA, conducted the validation / verification outside of their normal work hours, without any NASA facilities or equipment. This does not appear to be the case here. [[Special:Contributions/162.158.252.197|162.158.252.197]] 22:59, 16 December 2015 (UTC)

(for [[Special:Contributions/199.27.128.118|199.27.128.118]]) Your edit of <blockquote>But while they hooked it up to a measurement apparatus, applied RF input and measured changes in the apparatus, their interpretation of the experiment conducted in an air-filled stainless-steel chamber as a tiny ''thrust'' only explainable in terms of new (undefined) physics under the moniker of "quantum vacuum virtual plasma" is an extraordinary claim on very weak data.
