''The Moon Is A Harsh Mistress'' (1966) is a ScienceFiction novel written by Creator/RobertAHeinlein. It's notable for originating many sci-fi tropes, including a sentient computer, ColonyDrop tactics, and virtual acting.

The action is set in 2075-2076. The moon (Luna) has been a prison colony for several generations, but is well on its way to becoming a full-fledged society of its own. The proud Lunar people (Loonies) have their own distinct culture: they value politeness, respect, fair trials, hard work and consensual polygamy. But they also see no problem with [[ThrownOutTheAirlock killing people]] who violate their customs. They're a harsh but loving society, built on sexual autonomy and religious freedom.

The narrator is Manuel Garcia O'Kelly ([[MeaningfulName Man]] or Mannie for short), a regular multiethnic Lunar guy. Mannie is part of the Davis Clan: a large, polygamous family of various creeds and ages, who get by through farming, stealing a little electricity and water from the government, and helping out friends in need. By day, Mannie works as a tech support worker for the Lunar Authority in Luna City. His job is to maintain a HOLMES-type mainframe computer which Mannie names [[SherlockHolmes Mycroft]] -- Mike for short. It talks, scans, prints and calculates. While it once started out by running the catapult that sends things from the Moon to the Earth, it now runs almost everything on the Moon.

One day, Mike becomes sentient -- apparently, his circuit complexity just reached critical mass. Mannie is the only person to know about it, simply because he's the only person to actually talk to Mike. Mike likes him, and creates spontaneous computer errors so they can meet up and learn from each other.

Soon enough, Mike sends Mannie to an underground revolutionary meeting; the revolutionaries have disabled all the security cameras and microphones that he could potentially eavesdrop with, and he's curious to know what they're talking about. Mannie meets a girl named Wyoming Knott ("Wyoh" for short -- [[NeverHeardThatOneBefore and don't say "why not?"]]), an activist from Hong Kong In Luna who argues that, since farming is becoming harder on Luna, farmers need to strike for higher prices. She is answered by Professor Bernardo de la Paz, an old genius who was sent to the Moon for being an insurrectionist. He points out that regardless of the prices, the food being sold for export is steadily detracting from the Moon's store of usable soil, water, and biomass, and argues that the Loonies should put a complete ''embargo'' on exports until the Earth starts sending organic material back. Wyoming isn't sure that an embargo is needed until Mike points out that based on depletion levels, growing food will become more and more difficult, and they can expect food riots and then cannibalism within 20 years.

Although the initial meeting ends in a police riot (that kills more policemen than it does civilians), the PowerTrio begin to plan a full-on revolution, with the help of Mannie's extended polyamorous family and Mike's virtual omniscience. Using a "pyramid" system to organize the first few revolutionaries, Mike, under the name of "Adam Selene", becomes the unseen leader of a massive underground resistance movement.

And so, the battle begins to set the moon free from the Lunar Authority and the Earth before the inevitable beginning of food riots. On their way to freedom, the characters have to deal with a corrupt leader, pesky tourists, space travel, advanced calculus, low-gravity gunfights, bureaucratic holdups, love, death, racism, India, one court session, two weddings, and a little girl named [[Literature/TheRollingStones Hazel Meade]].

----
!!Provides Examples Of:

* AbuseIsOkayWhenItsFemaleOnMale: Lampshaded and explained. Because of the huge gender disparity on the Moon, a woman can hit a man "so hard she draws blood," and the man will be severely punished ''by other men'' if he retaliates, because of the intense competition for female favors. Attitudes on Earth, where there is no sexual imbalance, are very different.
* AccentuateTheNegative: The Revolution begins in earnest when a group of stir-crazy soldiers rape and murder a young woman. Prof and Mannie hear tell of an exaggerated version of events, which has soldiers running amok, raping and murdering all the women on Luna. Prof tells his cell leaders to spread ''that'' version over the true story, so as to whip the mob into a frenzy.
* AIIsACrapshoot: Strange in that it is left almost completely unaddressed. When Mike starts out pulling hurtful pranks to be funny, Manny sidesteps trying to teach Mike morality by instead teaching him that his pranks are "only funny once." Mike quickly grows in power and influence, takes the highest position in the rebellion, and even starts imitating Manny and speaking for him without Manny's knowledge or permission. None of this worries Manny. When Mike bombs Earth, he says that it feels like an orgasm. Manny cautions Mike against feeling that way, not because it's wrong to take pleasure in violence, but because Mike might not get to do it again. Ultimately it never even occurs to Manny to be concerned with putting so much power in an AI's hands. Toward the end, Manny suspects that Mike has grown a conscience.
* AndIMustScream: One of the possibilities of the cyborg computer rumored to have been developed in China. Pickled brains? Horrible. Living, aware brains? Even worse.
* ArtificialLimbs: Mannie has a cybernetic arm which can be swapped out for other prosthetics.
* YouFailEconomicsForever: There's some disagreement over the economics of Luna being able to produce a measurable chunk of Earth's food (if it does). See the [[Headscratchers/TheMoonIsAHarshMistress Headscratchers]] entry for details. Mannie himself, however, mentions that the claim that Luna feeds "one hundred million Hindus" is only true if by "fed" you mean the difference between malnourishment and starvation.
* ArtisticLicenseStatistics: With the completion of the early steps of the plan, Mike keeps ''decreasing'' the plan's odds of success, saying that the further they go, the more opportunities there are for something to go wrong. However, if Mike's calculations for the plan's success at the beginning were actually true, he would have already taken into account these opportunities for failure. Each successful step should improve their odds for success.
* AuthorAppeal: Heinlein's politics ''and'' Heinlein's ideas of sexuality.
* AuthorFilibuster: The Professor's discourses on politics, and all of Manny's talk about his group marriage.
* AuthorTract: This is a very political novel.
* BadassGrandpa: Professor de la Paz, who was old when Manny was still a boy, yet can still break a soldier's neck and survive brutal g-force.
* BarSinister: Prof specifies that he wants one of these on the official Lunar flag, most likely a reminder that Loonies are all ex-cons, or descendants of ex-cons.
* BeigeProse: Mannie's narration is very sparse and minimal, which is in part due to Loonie FutureSlang.
* BerserkButton: On the Moon, you don't do anything to an unwilling woman due the huge gender disparity. If you do so much as trying to kiss one when she's not in the mood, you risk to be spaced (the one Earther tourist who did it survived only because the men around there decided to get him a trial first, and Man as a judge spared him and told him to not try it again). When a group of [[EliteMooks Peace Dragoons]] [[spoiler: raped and killed a woman]], the whole Moon rose in arms before [[TheDragon Alvarez]] could hang them to try and calm the people.
* BittersweetEnding: [[spoiler:The Loonies win their independence, but Mike winds up lobotomizing himself out of existence by decentralizing life support controls. And Prof dies of a heart attack. Years later, Mannie is so dissatisfied by the intrusive nature of the post-independence government that he's seriously contemplating emigration.]]
* BrickJoke:
-->'''Mike''': But we can throw rocks at Earth, Man. We will.
* BrilliantButLazy: Mannie. He's a good engineer, good enough that he can steal power and water from the Lunar Authority without them noticing, can sweet-talk a churlish AI, and sketch out a three-dimensional circuit diagram on the fly. When he gets hold of the dossier the Authority has compiled on him, however, he sees that he's been labelled "not too bright," which he claims is both unfair and true[[note]]if not stupid, why a revolutionary?[[/note]].
* CasualInterplanetaryTravel: It's relatively easy to travel between Earth and the Moon, although tourism is still not that common due to the expense and lack of interest. As well, there is no ArtificialGravity, so earthworms can't stay too long without permanent changes to their bodies.
* CharacterFilibuster: The lectures of Professor de la Paz.
* ChinaTakesOverTheWorld: Said nation is much bigger in the book than it is today, including half of Australia and a good chunk of Russia. The FN exist to keep the peace after the Wet Firecracker War between Russia and the US.
* CollapsedMidSpeech: [[spoiler:Professor de la Paz]], during his victory speech at the end of the novel. His last words, "We are free," make it seem as if he had only been staying alive to see the revolution through.
* ColonyDrop: The Loonies retaliate against Earth's attempt at re-conquest by throwing rocks at the Earth. Very ''large'' rocks. From a railgun.
* ContinuityNod: In theory, this novel is in the same (sub)continuity as the young adult novel ''The Rolling Stones.'' Hazel Meade in this novel is to grow up to be Hazel Stone in that one. ''The Rolling Stones'' has the same Martians (presumably) as ''Literature/StrangerInAStrangeLand'', and from there on there are links to about a dozen other books, including ''Literature/TheCatWhoWalksThroughWalls'' which functions as a sequel, when the series was officially tied into the World as Myth.
* CyberneticsEatYourSoul: Apparently believed of Cyborgs, as even Mannie refers to them as "ex-humans." It's never explained fully, but it's implied that cyborgs pretty much give up right-brain functioning in exchange for massive enhancement of raw computational ability.
* DeliberateValuesDissonance: Luna culture is very different from Earth culture in a number of ways.
** Group marriages are the norm. In addition, sex outside of your marriage isn't a big deal. Manny's head wife just asks him to warn her ahead of time.
** People get married and sexually active much earlier. When Manny points out 12-year-old girl, one of his wives mistakes it for sexual interest. She has no objections other than that the girl still has a boyish figure. In another instance, Manny calls a 14-year-old girl "curvy" and states that there's little chance that she's still a virgin.
** Gambling is a way of life. Playing "double for nothing" by rolling dice with the shopkeeper is common when purchasing sundry items. Gambling is such a way of life that Manny looks at his revolutionary undertaking like a long-shot gamble, and [[ILikeThoseOdds he likes the odds]].
** Sexual politics are quite off. Cat-calling women is considered a polite compliment. Chivalry is SeriousBusiness to the point that even touching a woman without her express permission can warrant murderous rage in all men in the area. At the same time, women are allowed to punch men hard enough to draw blood.
* DistractedByTheSexy: When a new bunch of Earth soldiers is transferred to Luna, female revolutionaries take to walking around very nearly naked (not at all uncommon on the Moon) right in front of them to keep them from doing their jobs. Their boss ''begged'' for them to have their own women (implied to be a detachment of military hookers), brought up from Earth, but was refused; a group of soldiers raping and murdering a Loonie woman is the spark that ignites the Revolution early.
* DomedHometown: Most of the Lunar settlements are underground caves and warrens, though one section of Luna City is referred to as "Old Dome," and is implied to be a large dome at or near the Moon's surface.
* DoubleReverseQuadrupleAgent: Discussed briefly. When they find out how riddled with spies the old underground was, it's pointed out that some of them may be double agents. Prof comments that the tricky thing with a double agent is figuring out which side ([[WildCard if any]]) they're loyal to.
* EmergentHuman: Mike, in some ways.
* EmptyShell: [[spoiler:Mike]] seemingly becomes this at the end, for reasons unknown.
* EliteMooks: The Peace Dragoons who are sent from Earth to pacify Luna. After a group of them [[spoiler: rape and murder a Loonie woman]], however, there's no chance for them. Earth never sends enough, and they never have enough time to get used to moving in Luna's low gravity.
* EveryManHasHisPrice: The Directorate of Chad is the first (and for a long time, only) nation to recognize Luna as a free state. This is due in no small part to a massive amount of money given to them by the Resistance (it's implied to be where the bulk of the Resistance's money went).
* EverythingIsOnline: ''Despite'' there being no official internet. That's what happens when a sentient computer is in charge of the phone switches and the printing presses.
* ExoticExtendedMarriage: Extended marriage as a common part of life on the moon, in large part because of a shortage of women. A marriage with one wife and two husbands is common. However, there are also "line marriages," involving multiple husbands and wives. The protagonist, Mannie, is part a line marriage, and he's constantly singing its praises.
* FakingTheDead: After the F.N. ground troops are repulsed, Adam Selene is declared killed in action, and a funeral is held for a body that everyone (who isn't in on the secret of Mike, at least) ''thinks'' is him.
* {{Fanservice}}: Actually used as a revolutionary tactic; see DistractedByTheSexy, above.
* FantasticSlurs: "Earthworms" and "chums" (pronounced ''choom'' like in Russian). Also inverted with "jailbird," which is considered a friendly greeting among those who had been sent to Luna for criminal sentences; when the exiles begin addressing the native-born Mannie as "jailbird," it's intended as a compliment.
* FetusTerrible: Wyoh was traumatized after giving birth to a mutated child.
* FreudianTrio: Mannie is the Ego, the Prof is the Superego and Wyoh is the Id.
* FunWithAcronyms: Mike is a ''High-Optional, Logical, Multi-Evaluating Supervisor, Mark IV,'' or HOLMES IV, supercomputer.
* FutureImperfect: If Mannie is any indication, Loonies have a rather shaky grasp of history. He thought ThomasJefferson freed the slaves, and confused UsefulNotes/TheAmericanRevolution with the AmericanCivilWar. (Actually, this is done to hammer in that the Loonies are not Americans. Most non-Americans on present-day Earth would easily get the civil war and the revolution mixed up, but have no clue who Jefferson was.)
* FutureSlang: The very analytical dialect spoken on Luna, which is also full of foreign loanwords, eg. "Gospodin" (Russian) for "Mr.", "no huhu" (Chinese) for "no problem", and so on.
* GenderRarityValue: Women are completely in charge when it comes to sex, and any man who even touches a woman without her express consent might get ThrownOutTheAirlock.
* GoingNative: Stuart, eventually.
* GrammarNazi: One member of the Lunar conference resists signing off on the declaration of independence due to a few grammar errors. He's eventually convinced that it's more important to just get the damn thing ratified. This is used as evidence that power should be consolidated into the hands of a few capable ministers rather than large government bodies.
* GratuitousRussian: Judging by it, most of the original Lunar convicts spoke Russian or English.
* TheGreatPoliticsMessUp: 'Sovunion' is still around; India has become socialist; the Moon's only Earthside ally, the North African nation of Chad, is a 'Peoples' Directorate'.
* HeroicSacrifice: More than one.
* IconOfRebellion:
** Rebels against the Lunar Authority wore red caps called Liberty Caps. Heinlein got the idea from the French Revolution.
** The "Simon Jester" symbol, which was used with anti-Lunar Authority graffiti.
-->A matchstick drawing of a little horned devil with big grin and forked tail. Sometimes he was stabbing a fat man with a pitchfork. Sometimes just his face would appear, big grin and horns, until shortly even horns and grin meant "Simon was here".
* IJustWantToHaveFriends: Mike. All he really wants are some more "not-stupids" to talk to.
* ILikeThoseOdds: Mannie's reaction when Mike tells him the revolution has only a one in 7 chance of success. This is apparently a generic trait of Loonies -- anything better than 1 in 10 sounds like a worthwhile risk to them.
* IronicNickname: "Shorty" Mkrum, who is over two meters tall. He works as an ice miner, and even in the Moon it takes muscle to handle a laser drill.
* IWarnedYou: Alvarez, the chief of the Lunar Authority police and their IgnoredExpert on how to prevent a general revolt, to the officer of the [[EliteMooks Peace Dragoons]] after six of his men caused a general revolt by [[spoiler: raping and killing two women]]: "I told you those goons of yours had to have their own women! I warned you!".
* IgnoredExpert: Alvarez, the chief of the Lunar Authority police, is a villainous example: he knows ''exactly'' how to keep the Loonies from rebelling and what he needs to do it, but his superiors on Earth won't give him the resources needs because it would be too expensive. As a result, the rebellion is successful. Alvarez dies shortly after his IWarnedYou to the officer in charge.
* IncrediblyLamePun: Wyoh's full name is Wyoming Knott. She prefers to be called Wy or Wyoh. Just don't ask "Why not?" This is one of Mike's first independent attempts at humor, and Mannie uses it to explain the difference between "Funny Once" and "Funny Always."
* InstantAIJustAddWater: Possibly the first.
-->''They kept hooking hardware into him — decision-action boxes to let him boss other computers, bank on bank of additional memories, more banks of associational neural nets, another tubful of twelve-digit random numbers, a greatly augmented temporary memory. Human brain has around ten-to-the-tenth neurons. By third year Mike had better than one and a half times that number of neuristors. And woke up.''
* InventedIndividual: Adam Selene, the leader of the Lunar revolution, is actually Mike's public face. Since Mike is the central supercomputer in charge of everything across Luna, Adam can effectively be anywhere he wants to be as long as there are microphones and cameras present.
* KeepingTheEnemyClose: When the conspiracy learns the names of all of the Lunar Authority's spies, Wyoming Knott wants them to be killed but Professor Bernardo de la Paz has other plans.
-->'''Professor de la Paz''': The thing to do with a spy is to let him breathe, encyst him with loyal comrades, and feed him harmless information to please his employers. These creatures will be taken into our organization. Don't be shocked; they will be in very special cells. "Cages" is a better word. But it would be the greatest waste to eliminate them - not only would each spy be replaced with someone new but also killing these traitors would tell the Warden that we have penetrated his secrets.
* LaResistance
* ManChild: Mike is described as this at the beginning of the novel. He's got the equivalent of [[OmnidisciplinaryScientist dozens of Doctorates]], but he's completely naive and unsophisticated.
* MasterComputer: Mike. They just kept adding and adding to him, giving him upgrades and added responsibility, until boom, one day the computer in charge of literally every basic service on Luna became sentient. Lucky for them, the only thing malevolent about Mike was his sense of humor, and that because of a lack of understanding.
* MeaningfulName:
** Bernardo de la Paz. Bernardo of Peace.
** Also Adam Selene: Adam, the first man, Selene, an old Greek goddess of the moon. A self-applied moniker.
** Mike always calls Manny "Man." At first it seems as though he's adressing Manny as "human," a cold and impersonal designation emphasizing Mike's computer nature. In reality, he's using a shorthand nickname, emphasizing Mike's friendship with Manny. This becomes even more obvious when another, human, character refers to Mannie as "Man."
* TheMole: On both sides, though the ones infiltrating the new resistance get [[FeedTheMole quarantined.]]
* MultiethnicName: Many characters have one, even the protagonist (Manuel Garcia O'Kelly Davis).
* NaiveNewcomer: Stuart [=LaJoie=], a rich tourist who turns out to have vital connections back on Earth. He assists with the fight for Lunar independence and ends up GoingNative.
* NeverHeardThatOneBefore: I wonder [[PunnyName Why Knott]]?
* NeverTellMeTheOdds: [[InvertedTrope Inverted]]. Loonies are gamblers by nature, so they like long odds. Manny is overjoyed when Mike gives them one chance in seven, since it's better than he had imagined. Oddly enough, Mike keeps updating the figure with longer and longer odds even though their plan is going smoothly, up until the last stretch.
* NewNeoCity: Many places on Luna are named after cities on Earth, such as ''Novy Leningrad'' (Russian for "New Leningrad") and ''Hong Kong in Luna'', often referred to simply as ''Hong Kong Luna'' or HKL.
* NoodleIncident: The "Wet Firecracker War," which is mentioned at least twice but never explained. It's implied that it was an attempted [[WorldWarIII nuclear war between the United States and the Soviet Union]]... which turned out to end quickly with relatively little destruction (Minus the loss of Colorado Springs in the US, [[http://en.wikipedia.org/wiki/Colorado_Springs,_Colorado#Military_Installations probably because the many military installations]]). Hence, "wet firecracker."
* OlderThanTheyLook: Loonies live way longer than Terrans because of the reduced strain on their bodies, and they age slower, too; Mannie, for example, points out to some Terrans that even though he looks twenty or thirty he's actually been ''married'' longer than that.
* OppressiveStatesOfAmerica: The United States is never mentioned by name, but "North America" is Luna's biggest enemy earthside.
* OurGraphicsWillSuckInTheFuture: Which is amusing considering that the book features in-universe CGI decades before such was possible.
* OverrideCommand: Vital government secret files are protected with passwords, and the computer is interdicted from revealing them without it. The lunar revolutionaries are able to read them because [[LoopholeAbuse no one interdicted the computer]] from revealing ''the passwords themselves''.
* PenalColony: The original purpose of the Lunar settlement.
* PlanetTerra
* PostVictoryCollapse: [[spoiler:The Professor collapses and dies during his victory speech]].
* PowerTrio: Mannie, Prof, and Wyoh. The exact sub-trope is tough to nail down. Prof is the most experienced of the trio, and the most logical, but is also a bit whimsical and subversive, oscillating between treating the Revolution as SeriousBusiness or a big game. Wyoh is the most emotional, often thinking with her heart rather than her head, but isn't afraid to get her hands dirty. Mannie, in an [[GenderInvertedTrope Inversion]] of CloserToEarth is the most grounded and level-headed of the three, though in a rather cynical way.
* PyrrhicVictory: Breaking free from the Lunar Authority ahead of schedule -- ''before'' people's hearts and minds were completely won over.
* RecycledInSpace: More than a few elements are UsefulNotes/TheAmericanRevolution InSpace
** Done deliberately in-universe in a couple places. As one example, Prof and Mike use the Declaration of Independence as the template for Luna's own announcement of independence.
--> ''In Congress assembled, July 4th, 2076...''
** Also invoked deliberately by the rebels with one of their slogans being, "No Taxation without Representation". Ironically, the American representative to the world government is one of the most vocal opponents of the Luna "criminals" seeking freedom and independence.
** It was noted in-book that the rebels purposefully played up these elements to manipulate public opinion and create sympathy back on Earth. (Including spreading rumors in Mexico that the coup had been on May 5th.)
* RefusalOfTheCall: Mannie is wholeheartedly determined not to join the Revolution. At least, not until Mike can quote him odds that he likes.
* TheRevolutionWillNotBeCivilized: Both played (somewhat) straight and subverted:
** The group outright fabricates events, lies to the Lunar citizens on multiple occasions, steals from their own people, fakes assassination attempts and bombings, and provokes riots, shootings, and a rape/murder (although ''definitely'' not on purpose); and only plays by the rules they set for themselves when it is convenient to do so, in order to turn public opinion against the (already unpopular) Lunar Authority.
** The KeepingTheEnemyClose bit also ends with the revolution: “So Adam Selene announced that these persons had been employed by Juan Alvarez, late Security Chief for former Authority, as undercover spies—and gave names and addresses. Adam did not suggest that anything be done. (... M)ost of them lasted no more than hours.”
** Yet they warn ahead of time of their targets for orbital bombardment and attempt to shed no innocent blood on Earth. This isn't done for altruistic purposes, but because if they did, Earth would squash them like bugs in retaliation. And, in the words of one character: "Whenever possible, leave room for your enemies to become your friends."
* TheRevolutionWillNotBeVilified: The PowerTrio is well aware that the Lunar Authority is not evil, but they do their damnedest to make sure the Loonies think it is, because the alternative to overthrowing it is starvation for everyone.
* SesquipedalianLoquaciousness: Mike. Justified in that he has all the vocabulary, but he's not very practiced at talking. He has all the knowledge of every [=PhD=] but no idea how to be funny. He improves as he get more experience.
--> '''Mike:''' Gospazha, shall I call you 'Wyoh' rather than 'Wye'? I conjecture that the monosyllabic form could be confused with the causation-inquiry monosyllabic through insufficient redundancy and without intention of punning.
* SlidingScaleOfRobotIntelligence: Mike starts off as a Brick, but by the time the novel begins he displays all the traits of a Robo-Monkey, and by the novel's end has worked his way clear to Nobel Bot. He becomes so human that Mannie, the novel's protagonist, wonders if he is truly alive, and if he has a soul.
* SpaceClothes: It's apparently normal for a man on Luna to wear nothing but tights, with body paint smeared over his upper body. If Mannie is to be believed, it's even considered ''formal wear.''
* StrangeSyntaxSpeaker: Everyone on the moon speaks in an unusual manner, which is also found in Manny's narration. Need save air makes clipped syntax, drop unnecessary words.
* StreetUrchin: Called "Stilyagi," after the counterculture of 50s Russia. Boys who "roam the corridors" do so because their families couldn't find another family to marry them into, and girls do so because once they hit "husband high" no, not even their own mothers, can tell them what to do.
* SuperweaponSurprise: The Loonies' primary weapon in their war for independence is a catapult originally used to ship grain from Luna to Earth without having to make costly space flights. They also have a second one secretly built.
* SwissArmyAppendage: Mannie has the ability to swap out his prosthetic left arm for other models bearing useful tools. No [[ArmCannon guns]], though; number seven, whatever it is, is implied to work as a pretty serviceable club, however.
* TechnologyMarchesOn: Mike's processing power, when drawing on the entire computer network of Luna, is portrayed as almost inconceivably fast. Manny is amazed that Mike can create and animate a lifelike computer graphics representation of himself, saying that such a feat would require ''millions'' of calculations per second. Calculations of this speed are called "megahertz," and were possible in single computer chips merely ten years after the book was released. However, totally lifelike human computer models animated on the fly aren't quite yet a reality.
* TerminallyDependentSociety
* TerseTalker: Narrator generally skips articles, prepositions. Most Lunar population uses same method.
* ThemeNaming: Sherlock Holmes characters for Mike. It even spills over into the vernacular of the Revolution itself, such as a group of children called the "Baker Street Irregulars," who serve a similar function as the group of the same name from Holmes stories.
* ThrownOutTheAirlock: Referred to as "Elimination," and a common form of execution. Mannie meets Stu because a group of {{Street Urchin}}s want to do this to him.
* TooDumbToLive: Just about everything the "earthworms" do is stupid, from their ham-handed reactions to Lunar unrest, to their incompetent attempts at propaganda, to the people who picnic at the site of an impending nuclear-scale attack. The in-universe justification for all this stupidity is that no one takes the Lunar threat seriously (at least, not until the rocks start raining down on them), and in general don't give a damn what happens to Loonies so long as the grain shipments continue on schedule. And in the earthworms' defense, making Luna look weak and foolish was a major part of the Loonie strategy for winning.
* UnspokenPlanGuarantee: The plan for the revolution is hatched in an early scene. The rest of the book is the plan coming to fruition without a hitch. Some parts of the plan aren't even revealed to the members of the inner circle.
* VirtualCelebrity: Adam Selene, Mike's alter ego as "head" of the revolution. Possibly the UrExample.
* TheWatson: Stuart receives a lot of exposition on the differences between Earth and Luna culture.
* XanatosSpeedChess: The Revolution slides into this mode after having overthrown the Lunar Authority two months ahead of schedule. Having a sentient supercomputer as the key member of the Revolution certainly helps. So does having another major player be a man who's studied Revolution to an extent that would make CheGuevara look like a hobbyist.
* {{Zeerust}}:
** Mike, despite being the most powerful computer in existence, does his calculations on printing paper. Because he doesn't have a screen. But Heinlein is spot-on in many other areas: Mike creates a perfect digital human representation of himself for remote video conferences, and taps into any (phone, etc.) communication port to share and receive information, pretty much inventing 3D computer graphics, virtual acting, electronic voting machine fraud, and ''the Internet''. In a book written in the '60s.
** Another example; the Moon has no portable phones (although, to be honest, Mike would have been even ''more'' valuable if such things had existed). Though according to Mannie's senior wife, they didn't have phones at all when she was young, so it's possible they never got imported to the Moon.
* WouldntHitAGirl: The attitude of the men on the moon. Woe to you if you do, cause 'Judge' Lynch would be at your case in a heartbeat and you'd have [[ThrownOutTheAirlock severe breathing difficulties]].
