When The Planiverse ?rst appeared 16 years ago, it caught more than a few readers off guard. The line between willing suspension of dis- lief and innocent acceptance, if it exists at all, is a thin one. There were those who wanted to believe, despite the tongue-in-cheek subtext, that we had made contact with a two-dimensional world called Arde, a di- shaped planet embedded ...more

A lot of people have written sequels and homages to Flatland , and most of them only managed to live up to the original by virtue of that original not being very good to begin with. When people call Planiverse ``a worthy successor'', though, they are doing it a disservice.

The Planiverse started its life as (what has consistently been called) a monograph titled Two-Dimensional Science and Technology, and much of the book's quality can be credited to Martin Gardner's picking up and advertising th

Simply one of the best and most detailed/well-thought-out alternate worlds ever presented in print. From the computer simulation (oh, how I wanted to play with exactly such a program) through which the protagonists make contact with a complex, living two-dimensional world, to the many illustrations detailing that world's flora, fauna, architecture, engineering, and art: a delight. Plus Yndred's a cool fellow.

Non so se la versione pubblicata nel 2000 e ripubblicata nel 2013 di questo libro sia più aggiornata rispetto all'originale del 1983 che mi sono comprato di seconda mano. Ma in fin dei conti già questa prima versione è molto interessante, perché porta alle conseguenze estreme quanto Edwin Abbott Abbott scrisse in Flatland. Quel libro era in effetti nato come una satira contro la società vittoriana, e gli abitanti bidimensionali non erano certo tratteggiati biologicamente oppure nella loro compet ...more

Recommends it for: Readers interested in computers, science, and technology.
This is a brilliant description of life in a two-dimensional world. The concept is that through the use of a computer simulation the instructor and his students gain contact with one of the inhabitants of the world. It is that contact that gives the details about the 2D world.

What makes this such a fascinating book are the many illustrations. From simple things like how do the inhabitants get past each other when traveling in opposite directions to complex issues such as the construction of thei

Such an addictive, wild journey of a book! Why this doesn't have more of a cult following, I will never understand.

While it isn't entirely flawless, I couldn't help but give it 5 stars. A book has not excited me this much in a very long time.

I think this is probably one of my all-time favorite books. It’s a novel with a plot, but it also goes super in-depth into how everything would work in a 2-dimensional world. And I mean everything - biology, astrophysics, chemistry, weather, transport and traffic, painting, musical instruments, writing, computers, everything. To go along with the fascinating worldbuilding there is a pretty gripping plot about a 2-dimensional being who befriends some 3-dimensional university students and takes ...more

The Planiverse: Computer Contact with a Two Dimensional World by AK Dewdney

The setting is a graduate program in the early 1980's. Computers are mainframes, time and resources are precious, and programs are primitive at best.

A group of students led by their professor decide to model a two dimensional world--with the deptyh and horizontal axis rather than the horizontal and vertical axes of Flatland. It starts as an exercise in pure physics, mathematics and computer science, until their model som

My mind rebelled at the obvious, to me at least, flaws in the logical premise of the book. I know this is fiction, but you have to draw the line somewhere. Straight from the prolog we get off on the wrong foot. The 2D world is in a computer. I am fine with that. The computer is in a high school. What? The world has been created by the students programing it. Your kidding right? When the 2D world encouters a 2D being that communicates with the students and teacher they see a graphical change to ...more

Takes the mind-blowing qualities of its inspirations, Edwin Abbott Abbott's classic Flatland and Charles Hinton's "An Episode of Flatland," and takes them to the next level. (Sorry. Couldn't resist.) Instead of generally exploring worlds of lesser and greater dimensionality than our own, Dewdney seeks to create a two-dimensional world with internally consistent rules of physics, chemistry, biology, and technology, and succeeds admirably. That he is also able to tell a funny, touching story abo ...more

This purports to be an account of a computer programming project to simulate of a two-dimensional world. 'Somehow' the software makes contact with a 'real' two-dimensional universe. Our author is able to communicate with one of the inhabitants via the keyboard as this flat fellow goes on an exploratory semi-mystical journey through his squashed world.

Unlike Edwin Abbott's classic (and dull) Flatland A Romance of Many Dimensions, this 2D world is a sideways cross-section: our hero and his friends

Of course this book begs comparisons to Flatland...though not as well known as that famous romp through a world with only two dimensions, I believe this book is much better. Dewdney put a lot of thought in the way a civilization must necessarily be set up in a two-dimensional world - how will the laws of physics affect these creatures and their world? How can a two-dimensional creature have a digestive tract without being cut in half? How to pass each other in the street? How to build a dwelling ...more

Whereas Flatterland was a sequel to Flatland and, likes its predecessor, focuses Moreno geometry and physics, Dewdney explores what a two-dimensional world would be like for sentient creatures similar to humans. It's predecessors (at least the two I previously mentioned) dismiss these questions outright but Dewdney takes them on and really pushes my thinking about these concepts even further. At times I felt the detail of the fiction was a little unnecessary but mostly I found the story of ...more

This is science-fiction with lots of science in it. It has really interesting description of physics and engineering of two dimensional world. Interestingly the book also gives you ways to imagine how the four dimensional world would behave. But the downside of the book is that it doesn't have enough story in it (may be because things are so limited in 2D world). Anyway anyone interested in science shold find this book interesting.

A fascinating book which may be literature but also speculative science and even philosophy. What would a world that functioned in only two dimensions really look like? How would the flora and fauna develop and if there was intelligent life how would they think and what would their spirituality be like. You need go no further than Planiverse.

I'm sad to get rid of this book because of it's uniqueness but the decluttering has to continue. I'm glad to have had a last read.

Even though I find the concept of this book super interesting, the book itself just bored me immensely. The same happened with Flatland, the original "two-dimensional universe" narrative. In both cases, I found the framing gimmick gimmicky, the prose tedious, and the math of the thing explained dryly and without clever insight. Maybe it's just me.

Absolutely fascinating book. The most detailed, plausible description of a 2-D world I have ever read. I was fascinated by all the descriptions of how biology worked in a 2-D world, as well as physics, geography, and engineering. A bunch of computer geeks somehow make contact with a 2-D creature in another universe through their computer. Again, utterly fascinating.

I loved this book overall. The narrative framing was effective, and the storytelling lubricated the exposition/world building just enough for consistent engagement. There were many little "aha" moments within it, and you can tell it was a ton of fun to develop. It resonated a lot more than Flatland. Recommended with any fan of world building!

Flatland done right.

A.K. Dewdney creates a detailed 2-dimensional world told in a charming academic setting.

The book starts out written in the dry style of a technical report but finds

I've read this twice, and enjoyed it thoroughly both times. A. K. Dewdney is great- right up there with Martin Gardner for making math, science, and (more specific to him) computer science interesting and fun.

The physical discussions of 2d systems, the biology and mechanics, are really fascinating. Even the sociology and civilization are interesting, but a lot of the framing storyline, about Dewdney and his graduate students, isn't particularly compelling.
