DIMENSIONS, DIMENSIONS EVERYWHERE!

Honestly, dimensions and the curiosity to discover them knocks my brain out sometimes! For junior scientists and physicists, dimensions have always been their area of interest. Have you ever imagined what dimensional world we live in? How many dimensions have we discovered and how do we come to know?
First, let’s get cleared with the concept of dimensions! If we talk about 1-D, we just have a straight line. And then we have 2-D, where you have squares, circles and rectangles. 2-D can be described as looking at the world through the eyes of a flatworm! If we lived in a 2-D world, we would not have been able to eat. Here is the theory: if we eat something, we need a stomach to store and digest it, which is not possible in 2 dimensions. Whatever we eat comes out of the body from the other end.
If we are a flatlander (a person who lives in a 2-dimensional world), and if we are placed in a closed square room, there is no way to escape from that room. And if a person from 3-dimensional world tries to pull off the flatlander from 2-D to a 3-D world, then to other flatlanders it may look like, that flatlander has vanished into thin air! Just think about it. (image2)
To a flatlander walking, there are only two directions east and west, but no north and south. A flatlander can only walk sideways without changing the position of his heart or to the direction where he is facing, either upwards or downwards. We, thus, prove that we have a three-dimensional world.
A 3-D world is a complex world of cubes and spheres! In 3-D we can express our identities by the height and weight that we have! These are the physical dimensions we are talking about! But we are not static, lifeless objects. We grow, physically and intellectually, with TIME! So don’t you think that
