AOTW: The Fourth Dimension App Explains Everything 4D

The human mind is amazingly complex, able to imagine anything we want in our “minds eye”. You can sort of see it, but the picture is not really complete, blurry and needs a lot of focus to complete. But you know this, you’re human. (hopefully) We can even imagine pictures that don’t exist. Especially that don’t exist. So, it would seem that we would have a fairly easy time imagining a fourth dimension. Like, what is it? I can’t even formulate any examples of guesses of the fourth dimension would look like. Our brains just can’t process this.

To explain this problem, many people use the popular “Flatland” example. Imagine a place that only lives in 1 dimension. These people can only move up and down on a flat line. That’s it. They’re just points on a line. If you were one of these people, the possibility of going sideways would be impossible. They wouldn’t even know what “sideways would be. Now imagine a 2D world. Flatland. These people are shapes, who only know moving up, down, left and right. If we speculate what it would be like, such as in the 2007 animated movie “flatland”, people could only see lines. But they could move.

They of course would think of a “3rd dimension” as a dumb theory that nobody would take seriously. It just wouldn’t be possible to them. This is the basis of the story, Flatland – A Romance Of Many Dimensions, by Erwin Abbott, set in Shapeland, or the 2D world. The narrator, named simply “the Square”, guides the reader through this victorian era like place, full of castles and kings. The Square eventually visits “Lineland” and “Spaceland”, the latter of which he couldn’t even imagine beforehand. This great novel was written in 1884, and still holds up logically true today.

But back to the fourth dimension. There are some ways to imagine the fourth dimension, such as the shape of a tesseract. A tesseract is 4D shape, when translated into a 3D shape looks like a cube inside a cube, with lines connecting the corners. But what does it look like in the fourth dimension? Well, that’s where the app The Fourth Dimension app comes in. This app shows you the answer to this and more is an interactive and animated page by page story. The app thoroughly explains everything about the fourth dimension, and the whole thing takes about 10-15 minutes to complete, though totally worth it. With sprinkles of humor throughout, going through The Fourth Dimension app is a great learning and entertaining experience.
