FREE THE PLANIVERSE: COMPUTER CONTACT WITH A TWO-DIMENSIONAL WORLD PDF

The world is three dimensional, but everyone knows what one dimension or two dimensions are. Simply put, it is easy to recognize a line as being one dimensional and a square as two dimensional. However, does that really explain the idea of two dimensions? Dewdney's The Planiverse, a world with only two dimensions is discovered in the lab of a computer science department. Dewdny originally created a project for a class which would simulate a two dimensional world. Yendred, which is how the group referred to YNDRD, shows much of how things might operate in such a world. While this greatly worries Alice Little, Dewdney's course assistant, the class reaches the conclusion that it was most likely just a mistake The Planiverse: Computer Contact with a Two-dimensional World by a misreading of bits because the FEC soon continues to behave normally. However, YNDRD appears on the console a second day, and it becomes apparent that he is not a mistake, but something beyond what was expected. Yendred begins to talk with the students, understanding and using English in forms other than previously programmed for FECs. Although Yendred at first appears like a FEC, he begins to morph on screen from the triangular two armed FEC into a four armed being with a much more complicated body anatomy. During the first few week of contact, the class learns about Yendred's environment. They explore his underground house as well as follow Yendred and his father on a fishing trip on fiddib har, the sea by his house. The house as well as the fishing trip really begin to explain how things operate in this two dimensional world. This is when the class begins to really think about Arde differently from Earth. Although many things are similar, the absence of a third dimension really changes things that seem so common on Earth. For example, the fishing boat only needs to travel in two dimensions and cannot turn, therefore it has no real front or back. The second week, Yendred leaves his home to travel east. Eavesdropping on Yendred's conversation, The Planiverse: Computer Contact with a Two-dimensional World class learns that he is heading towards Vanizla, in search of something. Then, another difference between Earth and Arde is discovered. When Yendred first crosses paths with another Ardean, Tssil, one of them must lie down on the ground while the other walks over them in order to continue in their original directions The Planiverse: Computer Contact with a Two-dimensional World they cannot merely pass by each other. After parting with Tssil, Yendred explains that they are, or were, in a certain relationship, but that instead of the possibility of marriage, he has decided to go towards Vanizla. Once Yendred arrives in Is Felbt, a city en route to Vanizla, a The Planiverse: Computer Contact with a Two-dimensional World system is implemented which involves Westbound Ardeans walking into a covered pit allowing the Eastbound Ardeans to cross over, and then vice versa. Besides walking, Yendred also travels by balloon, a rocket, and a train. While in Is Felbt, much of the technology on Arde is explained to the computer science class on earth. At this point though, the class has begun meeting in the lab at night in an attempt to stay away from a repeat of a story in a tabloid about the discovery of a 2DWORLD. The The Planiverse: Computer Contact with a Two-dimensional World of the computer science department tells Dewdney to stop whatever it is that he is doing. Therefore, the entire class now has a greater sense of secrecy about the work that they are doing. But, they cannot merely stop exploring Yendred's world. Especially not as they learn about the two dimensional computer in the Punizlan Institute, only one of the more advanced engineering creations in Arde. During the last stretch of his journey, Yendred and his traveling companion, Tba Kryd, come under attack of a giant Bes Sallur, a snake like creature in Arde. The Bes Sallur, which can fly by trapping the air underneath it, traps the two travellers underneath its body and kills Tba Kryd. This situation truly shows how attached some in the class have become to Yendred, such as Alice. With the help of the class, who are very worried about Yendred's life at this point, Yendred is able to kill the Bes Sallur and escape with only an injured wrist. Yendred finally finds Drebk, a character who seems to be able to enter a third dimension, even while on the two dimensional world of Arde. He is known for being able to disappear and then reappear in a different place, and it seems that the way in which he does this is by going into a third dimension and then coming back into two dimensions. Through his time with Yendred, Drebk takes him away from the computer science class. There is some knowledge that Derbk possesses and that Yendred desires to know. However, in learning it, he will have to give up his life as it is, including the communication with Dewdney's class, his friends. The story in The Planiverse finally ends as Yendred leaves the two dimensional world with Drebk, leaving his Earth friends for good. This ends the novel with the speculation of perhaps the world having more than three dimensions. That perhaps a two dimensional world could exist, since no one could ever see it even if it was right in front of them since it would infinitesimally thin.

Overall, it is an intriguing book to read, The Planiverse: Computer Contact with a Two-dimensional World the general tone is of scientific inquisition, something I enjoyed significantly. The intricate animal biology, the mechanical constructs of the Planiverse mechanics and the allied descriptions, are interspersed with occasional parallels satirical? 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. Goodreads helps you keep track of books you want to read. Want to Read saving….

The Planiverse started its life as what has consistently been called a monograph titled Two-Dimensional Science and Technologyand much of the book's quality can be credited to Martin Gardner's picking up and advertising that monograph in Scientific American ; dozens of clever people, including physicists, geologists, and engineers, wrote in with elaborations, corrections, and suggestions, almost all of which apparently made it into the novel. The story itself isn't all that interesting—it lacks Flatland overt satire, which is probably for the best; when Stewart tried to include a feminist message in Flatterlandit just came off as ham-fisted and patronising—but it doesn't really need to be. Flatland 's asshole sphere is traded for a bunch of college students and a teleprinter which is adorableits top-down view for a more interesting side- scroller, and its endless confusion over dimensions for an exploration of the physical implications of a two-dimensional world. The result is a compelling novel which I'm surprised hasn't been made into a short film or video game yet. Apparently it inspired Creatures dude, remember Creatures? Actually, if anyone wants to do the art for a game, I'm up for the programming side of things. View 1 comment. May 21, Jlawrence rated it it was amazing. 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. Jun 22, Sinjin rated it it was amazing. This book taught me to appreciate the third dimension. Jun 06, Peter rated it really liked it. A delightful exploration of an alternate universe which had me looking at our 4 dimensions in a whole new way.

Of the thousands of books I have read during my lifetime, The Planiverse ranks among my top three. Perhaps that The Planiverse: Computer Contact with a Two-dimensional World why I am reading it for my third time. This is an excellent read, especially for the science minded readers. 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. Jan 24, Satwik rated it liked it. 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. Jul 13, Alexander rated it really liked it. 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. I found the students to be no different from Yendred the Ardean: two dimensional. They were unnecessary characters that didn't contribute The Planiverse: Computer Contact with a Two-dimensional World 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. Jun 07, Mark White rated it it was amazing.

The writing style is very economical and The Planiverse: Computer Contact with a Two-dimensional World 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. Aug 16, Stoa rated it really liked it. Flatland for speculative fiction fans, instead of Victorian-era satire. Two-dimensional biology and physics are given amazingly detailed treatments. Really interesting read The Planiverse: Computer Contact with a Two-dimensional World for a general audience. Wish it was much longer. Planiverse: A novel in many dimensions

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.

When The Planiverse? 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 in the skin of a vast, balloon-shaped space called the planiverse. It is tempting to imagine that those who believed, as well as those who suspended disbelief, did so because of a persuasive consistency in the cosmology and physics of this in? This was not just your r- of-the-mill universe fashioned out of the whole cloth of wish-driven imagination.
