Flatterland is a 2001 book written by mathematician and science popularizer Ian Stewart about non-Euclidean geometry.[1][2][3][4] It was written as a sequel to Flatland, an 1884 novel that discussed different dimensions.
Key Information
Plot summary
[edit]Almost 100 years after A. (which we find out stands for Albert) Square's adventures that were related in Flatland, his great-great-granddaughter, Victoria Line (Vikki), finds a copy of his book in her basement. This prompts her to invite a sphere from Spaceland to visit her, but instead she is visited by the "Space Hopper" (a character looking somewhat like the "Space Hopper" children's toy with a gigantic grin, horns and a spherical body). The Space Hopper, more than being able to move between Flatland and Spaceland, can travel to any space in the Mathiverse, a set of all imaginable worlds. After showing Vikki higher dimensions, he begins showing her more modern theories, such as fractional dimensions and dimensions with isolated points. Topology and hyperbolic geometry are also discussed, as well as the Projective "Plain" (complete with intersecting "lions") and the quantum level. Hopper and Victoria also visit the Domain of the Hawk King to discuss time travel and the theory of relativity.
How to Escape from a Black Hole
[edit]This is a diagram explaining how to escape from a black hole as mentioned in the book.
- You are outside the black hole.
- You have fallen into the black hole. A future version of yourself (4) appears and gives you a portable white hole. You use the portable white hole to escape the black hole.
- Another future version of yourself (6) appears and gives you a time machine.
- You go back into the black hole and give the past version of yourself (2) the portable white hole.
- You use the time machine to go far enough into the future (i.e. millions of years) that the black hole has evaporated due to Hawking radiation.
- You then travel back in time and give the past version of yourself (3) the time machine.
- You are now outside of the black hole.
The dashed red line indicates the path of the portable white hole (clockwise). The dashed blue line indicates the path of the time machine (counterclockwise). Movement from the bottom towards the top generally indicates movement forward in time (not to scale) and vice versa.

Background
Relation to Flatland
Flatterland serves as a direct sequel to Edwin A. Abbott's 1884 novella Flatland: A Romance of Many Dimensions, which depicts a two-dimensional world inhabited by geometric shapes where society is stratified by the number of sides a figure possesses, with lines at the bottom and polygons higher up. In this society, the narrator, A. Square—an equilateral triangle—experiences a visionary journey to one-dimensional Lineland and three-dimensional Spaceland, challenging the Flatland inhabitants' perception of reality and dimensionality, though he faces persecution upon his return.[1] Building on this foundation, Flatterland by Ian Stewart continues the narrative over a century later, introducing Victoria Line (Vikki), A. Square's great-great-granddaughter, who lives in a modernized Flatland that has evolved through scientific advancements since the Victorian era.[1] Vikki discovers her ancestor's diary, mirroring A. Square's original encounters with higher dimensions and prompting her own interdimensional explorations guided by enigmatic figures, thus extending the theme of dimensional awakening while updating the cosmology to reflect contemporary mathematical insights. This sequel contrasts the rigid, hierarchical Flatland of Abbott's time with a more dynamic, revolutionized version, emphasizing progress in understanding space and dimensions.[1] Among historical sequels to Flatland, Dionys Burger's Sphereland (originally published in Dutch in 1957 and translated to English in 1960) revisits Flatland's descendants grappling with spherical geometry and relativity in a post-revolutionary society. In contrast, Flatterland distinguishes itself by incorporating 21st-century scientific concepts, such as advanced topology and quantum ideas, through Vikki's adventures, rather than focusing solely on mid-20th-century physics as in Sphereland.[1]Author and Influences
Ian Stewart is a British mathematician born in 1945, who earned an MA from the University of Cambridge and a PhD from the University of Warwick.[4] He joined the University of Warwick as a lecturer in 1969 and later became a professor, serving until his retirement as Emeritus Professor of Mathematics, where he taught for 38 years.[5] Stewart is renowned as a prolific author and science communicator, having published over 160 books that span academic texts, popular science, science fiction, and fantasy, with a focus on making complex mathematical concepts accessible to general audiences.[5] His notable works include Does God Play Dice? The Mathematics of Chaos (1989), which explores chaos theory, and contributions to Scientific American's "Mathematical Recreations" column from 1991 to 2001, where he popularized recreational mathematics and symmetry.[4][6] The primary intellectual influence on Flatterland (2001) was Edwin A. Abbott's Flatland (1884), which Stewart reimagined as a modern sequel to update its exploration of dimensions for contemporary readers.[3] Stewart's broader influences stem from his deep engagement with recreational mathematics, chaos theory—as detailed in his writings on nonlinear dynamics and unpredictability—and symmetry, a recurring theme in his books like Fearful Symmetry: Is God a Geometer? (1992), which connects geometric patterns to natural phenomena. Additionally, his exposure to modern physics, including quantum mechanics, informed the book's blend of mathematical exposition and speculative ideas, drawn from collaborations and his own research on pattern formation and mathematical biology.[7] These interests shaped Flatterland as a narrative vehicle for discussing non-Euclidean geometry and higher dimensions, building on Abbott's satirical framework. Stewart wrote Flatterland to blend fictional storytelling with mathematical education, creating a sequel that revives the spirit of Flatland while incorporating 21st-century scientific insights.[6] His distinctive style features humor, puns, and whimsical fictional guides—such as the character Space Hopper, a multidimensional tour director—to demystify abstract concepts, a technique honed through his experience as a science communicator in books, radio, and television.[6] This approach reflects Stewart's belief that effective mathematical writing requires narrative engagement akin to fiction, ensuring accessibility without sacrificing rigor.[6]Publication History

Characters
The protagonist of Flatterland is Victoria Line, commonly known as Vikki, a precocious teenage girl from Flatland who embodies the curiosity and rebellious spirit of modern youth challenging the rigid dimensional and social norms of her two-dimensional world.[11] As the great-great-granddaughter of A. Square from the original Flatland, Vikki discovers her ancestor's hidden diary in the attic, which sparks her quest for understanding beyond Flatland's boundaries and propels the narrative forward through her adventures in the Mathiverse.[3] Her character arc evolves from initial skepticism about higher dimensions to profound enlightenment, as she grapples with increasingly abstract mathematical realities, representing a journey of personal and intellectual growth.[16] Serving as Vikki's primary guide is the Space Hopper, a whimsical, smiley-faced transdimensional entity depicted as a two-dimensional projection of a higher-dimensional being, often likened to a 1960s bouncy toy for its playful hopping between realms.[11] This character drives the narrative by transporting Vikki across the eleven dimensions of the Mathiverse, offering humorous, pun-filled explanations that lighten the exploration of complex ideas and contrast sharply with the somber, didactic tone of the original Flatland.[17] The Space Hopper's witty exposition style not only facilitates Vikki's discoveries but also injects levity into the story, making abstract concepts accessible through banter and visual gags.[3] Supporting characters in Flatterland personify various mathematical concepts, enhancing the narrative by illustrating key ideas through their interactions with Vikki and the Space Hopper. For instance, Schröger's Cat appears as a paradoxical feline embodying quantum superposition, while the Mandelblot, a resident of Fractalia, represents fractal geometry with its intricate, self-similar form.[3] Other figures include the Charming Construction Entity, which aids in building dimensional structures, and Moobius the one-sided cow, a humorous depiction of non-orientable surfaces like the Möbius strip, providing milk in Klein bottles to underscore topological quirks.[18] Vikki's family members, such as her father Grosvenor Square—who views A. Square as the "black sheep" of the lineage—offer grounding in Flatland's societal constraints, while figures like Stephen Hawk King, ruler of a domain involving black holes, contribute to episodic encounters that advance Vikki's enlightenment without dominating the central duo's dynamic.[11]Plot Overview
In the year 1999 of Flatland society, a century after the events chronicled by A. Square, young Victoria "Vikki" Line discovers her great-great-grandfather's long-hidden diary in the attic of her family home.[19] The diary reveals a secret code that Vikki decodes, inadvertently activating a Virtual Unreality device and opening a portal to higher dimensions.[11] This summons the Space Hopper, a bouncy, smiley-faced interdimensional guide resembling a toy, who arrives to whisk Vikki away on an educational tour of the Mathiverse, a Platonic realm encompassing various mathematical and physical wonders beyond Flatland's two-dimensional confines, allowing exploration of concepts like fractals, topology, and higher dimensions.[1] Vikki's journey unfolds episodically across diverse realms, beginning with a visit to Spaceland, the familiar three-dimensional Euclidean world, where she adjusts to perceiving depth and volume.[1] She then ventures into the Fractal Forest, encountering self-similar structures like the intricate Snowflake Helge and the bustling Quadratic City overseen by the Mandelbrot Set, illustrating infinite complexity at every scale.[1] Further adventures take her to Topologica, home to shape-shifting entities such as the Doughmouse and Moobius the Cow, demonstrating topological transformations; the Projective Plain, where she evades illusory Projective Lions; and Platterland, a non-Euclidean domain of curved hyperbolic spaces that defy Flatland's straight-line logic.[1] In quantum-inspired Cat Country, Vikki navigates probabilistic subatomic landscapes with feline inhabitants, while in Alberteinstein, she meets the Paradox Twins and grapples with relativistic effects like time dilation.[1] The tour intensifies with encounters involving the Space Girls and the Hawk King in higher-dimensional territories, culminating in a perilous sequence where Vikki falls into a black hole, escapes via a white hole, and briefly utilizes a time machine to return to safety.[11] As the narrative builds to its climax, Vikki confronts profound concepts of infinity, multiverses, and a ten-dimensional supermanifold tied to advanced theories like M-theory, expanding her worldview to encompass the universe's potential shapes and scales.[1] Transformed by these experiences, she bids farewell to the Space Hopper and returns to Flatland, now equipped with a deeper appreciation for dimensional possibilities.[11] Back home, Vikki emerges as an advocate for greater awareness of higher dimensions within her restrictive society, challenging its anti-intellectual and gender-based prejudices through subtle teachings via the Flatland Interline network.[1] The story, structured across 18 chapters, weaves adventure with Socratic dialogues and light philosophical reflections, concluding on an open-ended note pondering the true geometry of the cosmos.[20]Scientific Concepts
Geometry and Dimensions
In Flatterland, non-Euclidean geometry is introduced through Vikki's guided tours to curved worlds, contrasting with the flat Euclidean plane of the original Flatland. In spherical geometry, Vikki observes a finite yet boundless space where parallel lines converge, as illustrated by her interaction with a sphere-painting rectangle, demonstrating how circles expand to a maximum size before shrinking due to positive curvature.[21] Hyperbolic geometry, encountered in the realm of Hyperbolica, features negative curvature where parallel lines diverge, allowing multiple parallels through a point not on a given line, and "straight" paths appear curved in models like the Poincaré disk, with triangles exhibiting angle sums less than 180 degrees.[21] These visits highlight how curvature alters fundamental properties like distance and parallelism, providing intuitive analogies for abstract spaces. Projective geometry is explored in the realm of Projectiva, where all lines intersect, including parallels which meet at a point at infinity, challenging Euclidean assumptions about perspective and introducing concepts like the projective plane. Vikki learns how projections preserve certain properties, such as the intersection of lines, and encounters finite projective geometries used in combinatorial designs, like arranging points and lines without parallels.[22] The book extends the dimensional exploration beyond Flatland's two dimensions, progressing to three-dimensional Spaceland and beyond, using analogies to build conceptual understanding. Vikki's journey with the Space Hopper reveals a third dimension as an "up-down" axis perpendicular to the plane, enabling projections of 3D objects like spheres into 2D circles that seem to grow and shrink.[21] Higher dimensions, up to 11, are depicted through tesseracts—four-dimensional hypercubes whose 3D projections resemble unfolding cubes—and further abstractions where additional dimensions act as variables, such as rotations or time as the fourth dimension in space-time.[21] For instance, a bicircle requires seven dimensions for full description (three for position, four for orientation), and string theory's 10 or 11 dimensions are curled at the Planck scale, imperceptible in everyday experience.[21] These analogies emphasize how higher dimensions allow resolutions to problems insoluble in lower ones, like untangling knots without cutting. Fractals and fractional dimensions expand the notion of dimensionality in Flatterland, introducing non-integer measures through self-similar structures encountered in narrative settings like a fractal forest. The Hausdorff dimension quantifies the complexity of fractals, where shapes like the Koch snowflake exhibit self-similarity: each iteration replaces line segments with scaled copies, yielding a boundary dimension greater than 1 but less than 2.[21] During Vikki's visit to a fractal island, the fractal dimension is calculated using the formula where is the number of self-similar copies and is the scaling factor; for the Koch snowflake, and , giving .[21] Examples include the Mandelbrot set, whose boundary fills space fractally despite embedding in a plane, and natural forms like ferns, demonstrating infinite detail at every scale and challenging integer-based intuitions of dimension.[21] This framework underscores fractals as geometries invariant under certain transformations, bridging classical dimensions with irregular, scale-invariant patterns.Topology, Relativity, and Quantum Ideas
In Flatterland, topology is vividly illustrated through Vikki's journey to Topologica, where the Doughmouse demonstrates rubber-sheet geometry by deforming a doughnut into a teapot, preserving intrinsic properties like the number of holes while altering extrinsic appearance.[21] This rubber-sheet analogy underscores topological invariants, allowing Vikki to grasp how shapes can be continuously transformed without tearing or gluing.[22] Moobius the Cow, a non-orientable surface creature, embodies the Möbius strip by providing milk from a single-sided body, highlighting how such surfaces challenge intuitive notions of inside and outside in lower dimensions. Klein bottles are explored as bottle-like structures that loop back through themselves, forming closed surfaces without boundaries in four dimensions, further emphasizing topology's focus on connectivity over metric distances.[22] Vikki's adventures delve into knot theory when she encounters tangled structures that can only be untied by invoking an extra dimension, illustrating how embeddings in higher spaces simplify topological complexities. Homeomorphisms are explained as continuous mappings that preserve topological features, such as the equivalence between a sphere and a cube under deformation, contrasting with rigid geometric transformations.[21] These concepts culminate in encounters like the Alexander horned sphere, a wild embedding that traps three-dimensional space, demonstrating pathology in topological embeddings.[22] Error-correcting codes are introduced in the context of information realms, where Vikki learns how redundant encoding in higher-dimensional "digit territories" allows detection and correction of errors in transmitted data, such as flipping bits in binary sequences to recover original messages, with applications to reliable communication.[23] The narrative transitions to relativity in the realm of Spaceland, where curved spacetime is portrayed as a dynamic fabric warped by mass, aligning with general relativity's depiction of gravity as geometry. Black holes emerge as singularities where spacetime curvature becomes infinite, trapping light and matter beyond the event horizon, with infalling observers experiencing extreme time dilation.[23] Vikki's escape from such a predicament involves wormholes—hypothetical tunnels linking distant spacetime points to white holes, which expel matter—and closed timelike curves that permit loops in time, enabling paradoxical yet mathematically consistent time travel. This exploration ties to the Lorentzian metric of special relativity, given by which measures proper time along timelike paths and underpins the causal structure allowing closed curves in curved spacetime extensions.[23] Quantum mechanics enters through Superpaws, a feline embodiment of Schrödinger's cat, who exists in superposition—simultaneously alive and dead—until observation collapses the wave function, illustrating the probabilistic nature of quantum states.[22] Entanglement is depicted in quantum interactions where distant particles remain correlated, defying classical locality, as Vikki witnesses linked outcomes across space.[24] Feynman path integrals are introduced via diagrams tracing all possible particle trajectories, summing their amplitudes to predict quantum behavior, including retrocausal influences in time travel scenarios.[22] The book briefly touches on string theory, positing fundamental particles as vibrations of tiny strings in ten dimensions, with branes as extended objects embedding our universe in higher-dimensional bulk space, offering a framework for unifying quantum mechanics and relativity.[25]Themes and Allusions
Mathematical Themes
In Flatterland, dimensions serve as central metaphors for comprehending the universe, extending beyond the Euclidean constraints of the original Flatland to encompass modern concepts like infinite-dimensional spaces and multiverses. The narrative progresses from the two-dimensional limitations of A. Square's world to explorations of fractional dimensions, such as the 1.26186-dimensional snowflake edge, and higher-dimensional frameworks that challenge perceptual boundaries. This metaphorical use of dimensions illustrates how mathematical structures can model complex realities, from curled extra dimensions at the Planck scale to the vast possibilities of multiversal theories.[22] The pursuit of a Theory of Everything forms a key narrative arc, paralleling efforts in string theory to unify fundamental forces like gravity, electromagnetism, and the strong and weak nuclear forces. Protagonist Vikki Square's journey, guided through transdimensional realms, symbolizes the mathematical exploration that transcends intuitive understanding, incorporating supersymmetry to link bosons and fermions via particle spin. In this framework, superstring theory posits particles as vibrating strings in a 10-dimensional universe, where extra dimensions are compactified, offering a potential reconciliation of quantum mechanics and general relativity. Vikki's odyssey thus mirrors the ambitious quest for a single mathematical description of all physical phenomena.[26][22] Imagination and abstraction are emphasized as essential tools for visualizing the invisible, such as four-dimensional shadows projected into lower realms, enabling comprehension of abstract geometries defined by spaces and transformation groups. The story critiques the rigid, anti-innovative society of Flatland as a barrier to such creative mathematical thinking, advocating for open exploration of symmetries and higher-dimensional transformations. This highlights how abstraction allows mathematicians to navigate concepts beyond direct sensory experience, fostering breakthroughs in understanding universal structures.[16] Philosophically, mathematics emerges as a universal language that transcends dimensional boundaries. This view underscores the incomplete yet powerful nature of mathematical inquiry, positioning it as a bridge across realities without delving into formal proofs.[22]Cultural and Real-World References
Ian Stewart's Flatterland incorporates numerous puns and wordplay to enliven its exploration of mathematical concepts, grounding abstract ideas in accessible humor. The protagonist's guide, the Space Hopper, is depicted as a bouncy, spherical entity resembling the popular 1960s children's toy of the same name, complete with a grinning face and horns, serving as a playful mentor through multidimensional realms.[27] Other character names draw on mathematical puns, such as Moobius the one-sided cow, a nod to the Möbius strip, and the Mandelblot, evoking the Mandelbrot set. Realms in the Mathiverse also feature witty nomenclature, like the Projective Plane, which alludes to projective geometry while evoking a flattened, illusory world.[3] The narrative weaves in pop culture allusions to enhance its whimsical tone, drawing stylistic inspiration from Lewis Carroll's Alice's Adventures in Wonderland through its fantastical voyage structure and encounters with eccentric entities. Quantum mechanics appears via Schrödinger's Cat, personified as a character who embodies superposition and uncertainty, bridging scientific paradox with literary trope. These elements echo the absurd, universe-spanning adventures in Douglas Adams's The Hitchhiker's Guide to the Galaxy, though Stewart's focus remains on mathematical satire rather than pure comedy.[3] Real-world scientific nods anchor the story in late-20th-century discoveries, including references to the cosmic microwave background radiation, which supports discussions of the universe's flat geometry and Big Bang origins. Images from the Hubble Space Telescope are invoked to illustrate cosmic structures and expansion, reflecting 1990s advancements in observational cosmology. The book lightly satirizes academic mathematics through depictions of conferences as bewildering gatherings of abstract thinkers, mirroring real events like those of the International Congress of Mathematicians.[11]Reception and Legacy
Critical Response
Upon its publication in 2001, Flatterland received positive reviews for its accessible explanations of complex mathematical concepts. A review in Nature praised the book.[28] Similarly, Kirkus Reviews acknowledged its ambitious scope in touring late-20th-century mathematics, physics, and cosmology, though with reservations about its style.[11] The engaging narrative structure, updating the original Flatland through a modern lens, was highlighted in The Washington Post, which described it as a captivating sequel that expands on multidimensional exploration.[29] Reader reception has been solid, with an average rating of 3.7 out of 5 on Goodreads based on over 1,700 reviews.[18] Criticisms focused on the book's whimsical tone and depth of mathematical content. Kirkus Reviews deemed it "cloying" and "pun-filled," labeling it "high twee for the science set" due to its overly cute approach.[11] Reviews from mathematical organizations, such as the Mathematical Association of America (MAA), noted its fresh perspective through a female protagonist.[16] In academic contexts, Flatterland has been incorporated into university courses on geometry and multidimensional mathematics. For instance, it served as the basis for an educational play adaptation at Harvey Mudd College, used to illustrate topological and dimensional ideas in a theatrical format.[30] The book is frequently compared to Flatland, praised for advancing scientific themes but critiqued for diminishing the original's sharp social satire in favor of explanatory focus.[31]Influence and Reader Impact
Flatterland has found significant application in educational contexts, particularly for illustrating concepts of higher dimensions, topology, and non-Euclidean geometry. It is referenced in secondary-school mathematics resources to explore projective geometry and spatial visualization, helping students grasp abstract ideas through narrative analogies.[32] An adaptation of the book into a theatrical play has further supported its use in classroom settings, breathing new life into mathematical instruction by combining storytelling with demonstrations of dimensional concepts.[30] As part of the broader legacy of mathematical fiction, Flatterland has contributed to the popularization of advanced mathematics in the early 21st century, aligning with works like Brian Greene's The Elegant Universe in making complex topics such as space-time and hidden dimensions accessible to general audiences.[33] Its narrative approach has inspired sequels and imitations within science fiction, extending the Flatland tradition into explorations of multiverses and alternate realities in popular media.[34] The book continues to engage readers by fostering interest in mathematical visualization, often cited in discussions of four-dimensional geometry and tools for conceptualizing higher spaces.[35] Reviews highlight its role in challenging readers to rethink spatial intuition, promoting deeper appreciation for topology and relativity among non-specialists.[16]References
