Anirudh Aswal Posted May 19, 2016 Share Posted May 19, 2016 We live in a 3 dimensional world, where everything has length breadth and height. But what if we live in a 2D' world? Every thing will be smashed down to a single plane surface. And what that world would look like? This is what explained in a novel "Flatland" by Edwin Abbott in 1800. But what is a dimension anyway? For us dimension is a direction, which we can picture as a line. For our direction to be dimension, it has to be at right angle to all other dimension. so 1D is a line, while a 2D is two perpendicular line. (a flat surface) Eg. when we stretch a line from its ends perpendicular to the line, We get a 2D square. Similarly a 3D figure adds a third perpendicular. consider the same square. adding a third perpendicular to each ends give us a cube. So what will be a 4 dimensional figure? A five? 10?

Daecon Posted May 19, 2016 Share Posted May 19, 2016 A 4 dimensional square/cube would be a tesseract. https://en.wikipedia.org/wiki/Tesseract Link to comment Share on other sites More sharing options...
Yvtq8k3n Posted May 29, 2016 Share Posted May 29, 2016 (edited) Is more easy to think then to draw. Imagine that we are in 2D. Imagine that u have an square. Draw another prependicular next to it and link the corners and u will get an cub. Now u have an cube so we are at 3D. Now draw another cube and link each corner of the cube whit the other cube so u got a tesseract. Want go higher? Now we have an tesseract(4D) draw prependicular another tesseract and link each corner, congrates u are at the 5D. U will get this: Edited May 29, 2016 by Yvtq8k3n Link to comment Share on other sites More sharing options...
