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. 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 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 their underground dwellings all are covered.Of the thousands of books I have read during my lifetime, The Planiverse ranks among my top three Perhaps that is why I am reading it for my third time.This is an excellent read, especially for the science minded readers This book taught me to appreciate the third dimension. A delightful exploration of an alternate universe which had me looking at our 4 dimensions in a whole new way At the forefront, I think the sequel of Flatland appellation usually given to Planiverse does much disservice to it Rather, a simple Flatland inspired world ought to be enough to pay homage to Abbott s masterpiece without causing subconscious comparisons between the two while reading.Overall, it is an intriguing book to read, and the general tone is of scientific inquisition, something I enjoyed significantly Kudos to the author s imagination and his scientific rigor in wanting to make our At the forefront, I think the sequel of Flatland appellation usually given to Planiverse does much disservice to it Rather, a simple Flatland inspired world ought to be enough to pay homage to Abbott s masterpiece without causing subconscious comparisons between the two while reading.Overall, it is an intriguing book to read, and the general tone is of scientific inquisition, something I enjoyed significantly Kudos to the author s imagination and his scientific rigor in wanting to make our lower dimensional or were they brethren seem plausible to the skeptic minded More than a narrative structure, the book reads as a world building exercise and a sort of thinly veiled or rather with a thin padding of a story fable presenting the author s attempt at scientifically sound construction of 2D equivalents of the sciences The intricate animal biology, the mechanical constructs of the Planiverse mechanics and the allied descriptions, are interspersed with occasional parallels satirical with our own societies political constructs.On the down side, I felt it was very little story and too much world building A lot of excessive descriptions of the 2D universe gets a little stale after a while, especially the really redundant pieces towards the middle part Here is where the Flatland comparison is detrimental, since not only does Planiverse not enjoy the element of first time intrigue as did Flatland, but also lacks the general strength of story that was important in the latter Moreover, many ideas are repeated Although Planiverse adds a great deal to the universe and is considerably different from that of Flatland Some parts were laboriously slow moving, and I felt the ending was a bit too abrupt and perhaps, unnecessarily cryptic.Final Verdict A free time read A great read for those who have not read Flatland, a moderate to good read for those who have Enjoyable if you like world building books Such an addictive, wild journey of a book Why this doesn t haveof 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. A classic book about life in a two dimensional universe, written by a well known author Now brought back into print in this revised and updated edition, the book is written within the great tradition of Abbott s Flatland, and Hinton s famous Sphereland Accessible, imaginative, and clever, it will appeal to a wide array of readers, from serious mathematicians and computer scientists, to science fiction fans A little slow in the beginning, but a fascinating thought experiment in action This book not only sparked my imagination wondering what the rest of Arde looks like, but it pleased the analytical portion of my brain as well There is a surprising amount of real life science that backs up a lot of what is stated in the book I have no doubt that if we were able to observe a 2 dimensional world such as the one described in the book, a lot of the theoretical science would be confirmed I found the A little slow in the beginning, but a fascinating thought experiment in action This book not only sparked my imagination wondering what the rest of Arde looks like, but it pleased the analytical portion of my brain as well There is a surprising amount of real life science that backs up a lot of what is stated in the book I have no doubt that if we were able to observe a 2 dimensional world such as the one described in the book, a lot of the theoretical science would be confirmed I found the students to be no different from Yendred the Ardean two dimensional They were unnecessary characters that didn t contribute to the story much If you can look past the paper thin plot that sets up Yendred s adventures in the Planiverse, you won t be disappointed I recommend this book to anyone who enjoyed Edwin Abbott s Flatland , which should be mandatory reading before tackling this book Also if you are particularly interested in any of the STEM fields, please give this book a look There s plenty of science in here to excite you A technically fascinating look at a two dimensional universe this book is also a surprisingly sweet story of friendship, adventure, spirituality and self discovery with a wistful, bittersweet ending Vastlysophisticated in both plot and execution than Flatland, this is a fully functional two dimensional universe Yendred, the protagonist, is a fully formed and sympathetic character whose adventures will have you on the edge of your seat The writing style is very economical and that this i A technically fascinating look at a two dimensional universe this book is also a surprisingly sweet story of friendship, adventure, spirituality and self discovery with a wistful, bittersweet ending Vastlysophisticated in both plot and execution than Flatland, this is a fully functional two dimensional universe Yendred, the protagonist, is a fully formed and sympathetic character whose adventures will have you on the edge of your seat The writing style is very economical and that this is all accomplished in such a concise fashion is a lesson to authors who take two or three times as many pages to achieve far less I think this book should have broad appeal from early teens upwards Flatland for speculative fiction fans, instead of Victorian era satire Two dimensional biology and physics are given amazingly detailed treatments Really interesting read even for a general audience Wish it was much longer.
