By A.K. Dewdney

The yr is 1981, and within the desktop lab of a giant collage a gaggle of graduate scholars and their professor are not easy at paintings on their mainframe, graphically modeling an imaginary two-dimensional international. The venture goes good, terribly good, while one pupil unexpectedly notices that the realm they're development with their portraits application is . . . inhabited! So starts A.K. DewdneyÕs newly republished 1984 story of trans-dimensional discovery and communique. the scholars and their professor locate, to their astonishment, that they're speaking with Yendred, their merely touch within the 2nd global of Arde. initially disbelieving, they're quickly entranced through a universe within which staggering tiny creaturesÑindeed a whole remarkable worldÑexist exclusively on an x-y aircraft. This ebook, following within the footsteps Edward AbbotÕs 19th century vintage Flatland, is a cult favourite between mathematicians and computing device scientists. As one of those psychological puzzle or brain-teaser, it demanding situations and delights, inviting readers to visualize simply how a two-dimensional global may perhaps paintings. however the booklet can be a parable, serving as a cautionary story in regards to the problems of conversation from one completely alien global to a different, and suggesting that it's not simply two-dimensional Ardeans who miss out on past the the most obvious international ahead of their eyes.
