Mind Fuck: Day 8

Today I found out... another way of viewing the third dimension.

Imagining the third dimension is easy for us because we experience it daily. A three dimensional object has length, width, and height. However there’s another of understanding the third dimension: if we were to imagine an ant walking across a newspaper which is lying flat on a table, and we pretend that the ant is completely two dimensional when walking along this two-dimensional newspaper world... the paper can be folded around so that the two ends meet, thus creating a way for the Ant 'jump' across to the other side of his newspaper world instantly while everything still remains two dimensional.

In effect the Ant has “magically” disappeared from one position in his two-dimensional world and be instantly transported to another. We can imagine that we did this by taking a two-dimensional object and folding it through the dimension above, which is our third dimension. It is apparently more convenient for us to imagine the higher dimensions if we can think of the third dimension in this way... the third dimension is what you “fold through” to jump from one point to another in the dimension below.
