Friends, today we are talking about dimensions. I will explain you about 1D, 2D, 3D, 4D etc. So in this way firstly we have to know what is dimension ? Also, there are some interesting things about dimensions so lets start.
All the things of the universe are in dimensions which may be 0D, 1D, 2D, 3D but we can feel 4D by some techniques. If you have heard about 6D, 7D, 8D, 9D, 11D etc. Then i want to tell you friends these dimensions (6D, 7D, 8D, 9D, 11D etc.) are not exist in the universe. This is only a rumor for user attraction. So never believe on 6D, 7D, 8D, 9D, 11D and more in future. Now let we know about 0D, 1D, 2D, 3D and 4D one by one.
Zero Dimensional (0D) :
A point or a particle is zero dimensional because They have not any length, width, volume and mass. We can’t expand them in any direction but we can see them from our eyes. Then that object will be in zero dimension. A dust particle and a point by a sharp pen are good examples of 0D.
One Dimensional (1D) :
A line is one dimensional because all you need to describe it is one measurement, such as the line is 5 Meters long. A span of time is also one dimensional, such as 30 minutes. After all, I want to tell you that a line is perfect example of one dimensional because we can expand a straight line in only two directions. If we talk about time then time is running constantly without any break in a direction, for example if this time passed it will never come in you life.
Two Dimensional (2D) :
A flat shape would be in 2 dimension, such as a shape with Length and width but it has not any thickness then it will be in 2 dimension. If you are thinking of plotting points on a graph you need to know the x. y coordinates for the vertices.
Three Dimensional (3D) :
If you can feel any thickness or depth in anything, that things will be in three dimensional. In simple form if any object has length width and thickness or depth then that thing is 3 Dimensional. Also, if you are thinking of plotting points on a graph you need to know the x, y, z coordinates for the vertices. Almost all things of this earth are in 3D.
Four Dimensional (4D) :
4 Dimension is a special condition for dimensions. we can say that 4D is a artificial dimension because we have made it by some techniques. You ever heard about 4DX cinemas, here we can feel to fourth dimension. In these cinemas, if you are watching a 3D movie but the special thing is that you feel every moment with your body. For example in movie, if there is raining you will feel water drops on your body, if wind is blowing you will feel wind is touching your body, if frame is moving, your chair will also move etc. These types of techniques makes a combination of some three dimensions, after all we got a new dimension which we called 4D.
