Discworld / The Science of Discworld
The Science of Discworld
, by Terry Pratchett
, mathematician Ian Stewart, and biologist Jack Cohen, is one half Discworld
novel, in which the wizards accidentally create a universe without magic and are fascinated by the way it develops its own rules in the absence of Narrative Causality
, and one half popular science text, as Stewart and Cohen explain how the Roundworld Project (i.e., our universe) actually works.
It was followed by three sequels:
- In The Science of Discworld II: The Globe, the wizards must stop The Fair Folk preying on the superstitious folk of Elizabethan Roundworld, while Stewart and Cohen talk about the nature of storytelling and belief.
- In The Science of Discworld III: Darwin's Watch, the wizards must stop the God of Evolution from seriously confusing Charles Darwin, while Stewart and Cohen discuss his theory in more detail than they had to spare in the first book.
- In The Science of Discworld IV: Judgement Day, a sect of Omnian extremists start claiming Roundworld is evidence they were right all along about the shape of the world, and therefore it belongs to them, while a sceptical Roundworld librarian ends up on the Disc. Stewart and Cohen discuss the nature and practice of science, itself.
The Science of Discworld series contains examples of:
- Alternate History: Several in the later books, all of them ending with humanity failing to invent the Space Elevator before it's Giant Snowball Time.
- Arc Words: Each book has several core concepts that keep being re-stated in different contexts. The first book has Lies to Children and the "Space Elevator", which is a metaphor for doing something in such a way that it makes subsequent efforts easier, like building a space elevator so that you don't have to keep expending massive fuel payloads to launch things into space, or how DNA allows lifeforms to make copies of themselves by cheaply copying their existing genetic information. The second book uses the "make-a-human-being kit" for the set of cultural traits and social norms that a tribe uses to control the development of its offspring, and keeps asserting that humans are not in the genus of homo but are instead pan narrans, the "storytelling chimp".
- As You Know: Zigzagged in the fiction portions, in which Ponder uses this phrase out of politeness when he suspects Ridcully doesn't know something about physics; this gives him the chance to contrast Discworld physics (which the readers don't necessarily know) with Roundworld rules (which readers might know, but Ridcully doesn't).
- Beethoven Was an Alien Spy: William Shakespeare and Darwin, amongst others, are greatly influenced by the wizards.
- Bigger Is Better: The Lecturer in Recent Runes' attitude to creating life that will withstand Roundworld's regular cataclysms - it's a limpet with a base a mile across, that eats whales.
- Blob Monster: In the first book, Rincewind gets covered in morphless predatory life forms.
- Chekhov's Skill: The Luggage's ability to travel between worlds in pursuit of its master debuted in The Colour of Magic and was expanded upon in Eric. This ability is finally put to practical use in book II.
- Colony Drop: Happens repeatedly in the first book, once (of course!) right on top of Rincewind.
- The Constant: In the timelines in which Darwin fails to produce The Origin of Species, Richard Dawkins eventually does, suggesting that he is an evolutionary biologist in every possible timeline.
- Desperate Object Catch: Rincewind drops the glass globe containing Roundworld when the Bursar pops up suddenly, then just barely catches it with a Diving Save. Something similar happens in the fourth book when Marjorie chases a zealot who has stolen Roundworld and, when he is cornered, he throws it at her.
- Different World, Different Movies: When they write that intelligence appears to be useful enough that it would probably still have arisen is some form if we hadn't appeared (the fiction parts show a number of civilisations getting a foothold on Roundworld in much earlier epochs, only to be wiped out by cataclysmic disasters) they speculate that if sentient crabs had evolved on the Earth in humans' place, three of them might be writing The Science of Dishworld, about a bowl-shaped world that's carried on the backs of gigantic marine invertebrates.
- In-universe, the third book is about the wizards' attempts to ensure that Charles Darwin writes On The Origin Of Species, not Theology Of Species.
- Early-Bird Cameo: Roundworld itself, as Rincewind and Twoflower briefly travel there in The Colour of Magic. The Librarian briefly encounters Darwin in the first book.
- Exact Words: What are the chances of Ponder's thaum-splitting magical reactor "just blowin' up and destroyin' the entire university?" None at all. If it goes up, it won't just blow up the university - it'll destroy the entire Discworld.
- Expy: Ratonasticthenes for Eratosthenes, and Antigonus for Archimedes.
- The Fair Folk: In volume 2.
- For Want of a Nail: The numerous events that prevent Shakespeare or Darwin from producing their works in alternate Roundworld timelines.
- Hex also mentions how, in 1734, a German shoemaker named Joshua Goddelson left his house by the back door, setting in motion a chain of events that (somehow) leads to commercial fusion power in 2017.
- The Fundamentalist: The Omnian fundamentalists in the fourth book are so close-minded that they remain convinced only they know the True Word of Om even when the god in question manifests specifically to tell them to stop being idiots.
- Gainax Ending: The first book ends with a giant, unliving turtle being spontaneously constructed in Roundworld space. "Recursion Is Occurring."
- Gone Horribly Right: The Thaum Reactor was built for the purpose of creating more heat for the University in winter (The Senior Faculty were lukewarm on the subject of knowledge, but boiling hot when it came to frosty windows). The reactor ends up working too well- just before Hex channels the excessive magic into the Roundworld Project, the college becomes so hot that Ridcully dreams he's lost in a broiling desert, only to find reality no different in temperature.
- "How Did You Know?" "I Didn't.": Happens when the Dean sticks his hand into the nascent Roundworld project:
"That was a really very foolish thing you just did," said Ridcully. "How did you know that it wasn't dangerous?"
"I didn't," said the Dean cheerfully. "It feels... cool. And rather chilly. Prickly, in a funny sort of way."
- In Spite of a Nail: Apparently, if Darwin had become a believer in what we'd now call "intelligent design", Richard Dawkins would have been the author of The Origin Of Species, sadly too late to make a difference. So Dawkins would be a Darwinist even if Darwin wasn't.
- Interrupted Suicide: Rincewind repeatedly puts a fish back into the water, not realizing it's adapting to life on land rather than trying to kill itself.
- It Will Never Catch On: The wizards do this a lot, first claiming that planets are no place for life, that the sea is only place for a intelligent creature, that the primates will never amount to anything, and so on.
- Also, that the "terribly dull lizards" would never catch anyone's interest, such that any accounts of Roundworld prehistory will most likely skip over their era.
- Jerkass Has a Point: In the one of the science chapters in the first book, the narration notes that Rincewind's speech on how meaningless it is to build a life on Roundworld is with its tendency to destroy any civilization with giant snowballs and other disasters, while we might find it harsh, makes sense. Rincewind has seen the Roundworld on a far grander scale than any native has, so while we might enjoy living on it at the moment, the same could be said about the dinosaurs. Just ask them; You can't, can you. That's the point.
- Lies to Children: The Trope Namer. In the fiction sections, Ponder describes his thaumic reactor to the other faculty using Lies-To-Wizards, and Hex's reports mainly consist of Lies-To-People.
- Mage in Manhattan
- Magic Versus Science: The Roundworld Project's original intention was to create a place where magic could not exist, which was thought to be impossible.
- Magitek: Hex of course, and the Thaumic Engine is the magical equivalent of a nuclear reactor (going back to Pratchett's roots, as he made many similar comparisons in The Colour of Magic).
- Measuring the Marigolds: Averted in the science parts of the books.
- The Monolith: Parodied with the Dean's chalkboard-assisted lesson to the apes.
- Mythology Gag: Among the quotations at the beginning of the third book is Preserved J. Nightingale's version of Paley's "watch" quote, supposedly from a text called Watches Abroad.
- No Name Given: Reaches its climax here, with the wizards even naming elements things like "Runium" and "Wranglium" after their titles rather than their actual (unknown) names.
- Noodle Implements: While preparing for Shakespeare to write A Midsummer Night's Dream, the Wizards run into various problems that Ridcully solves via a set of noodle implements. Most of the time the reader can easily figure out what he is going to do with them (The sole exception being related to a folk remedy that is explained in one of the science chapters).
- Parodic Table of the Elements: It's the standard table, except with extra space for narrativium and octium.
- Reading the Stage Directions Out Loud: In Darwin's Watch, Hex makes several dramatic announcements to the wizards, and says the words "pause for dramatic effect" before saying the last word. Ponder eventually tells him that he doesn't need to to that.
- Retcon: The first book uses 'splitting the thaum' as a magical equivalent of 'splitting the atom'. In previous books, thaums were just an arbitrary measurement of magic (and with the competing Prime system) rather than the smallest possible unit of magic.
- Running Gag: In the second and third volumes, the Wizards find history has been meddled with and someone surnamed Nightingale has been inserted into a place someone else (William Shakespeare and Charles Darwin, respectively) should have been in.
- Science Marches On: Chapter 10 of Book Four illustrates the nature of science by devoting some space to the theories the first book favoured about the formation of the moon and the origins of life, and explaining why they're probably wrong after all.
- Space Elevator: One appears in Book One. In the later books, the wizards' goal is the continued existence of a timeline that contains it.
- Time Abyss: The elves and their Queen invade Roundworld in the time of early hominids, and are still hanging around in Elizabethan times. And one of the regular elves is mentioned as having outlived several Queens and preyed upon many previous worlds' inhabitants, which suggests it's witnessed multiple sentient species' complete evolutionary history.
- Timey-Wimey Ball: It's revealed in the fourth book that because Roundworld and Discworld are connected by L-Space, they've influenced each others' mythologies, meaning that when the wizards created Roundworld, they inadvertently altered their own history to create the Omnian doctrine of a spherical world.
- Welcome to the Real World
- What Did I Do Last Night?: Rincewind experiences this in The Science of Discworld II after the wizards spend the night drinking with William Shakespeare.
- The World Is Always Doomed: In the first book, the wizards become discouraged when Roundworld is repeatedly (As in, every several million years or so), hit by a large comet or asteroid.
- Year Inside, Hour Outside: Early in the Project, millions of years pass in Roundworld for every Discworld day. Later, Hex takes control of time's passage within the artificial universe, and can subvert, avert, invert or play this trope straight at will.
- Zany Scheme: The wizards' interventions. Particularly the Noodle Implements-heavy one in volume 2, where they invoke various folk remedies to ensure William Shakespeare is born a boy.
