Dimensions...

Not really a question, just sharing some thoughts.

I started thinking about this a while back. An array, Arr[n] is represented as a series of data, one after the other. Arr[n][n] is a grid of values. Arr[n][n][n] is a solid cube of values.

Then, to continue, Arr[n][n][n][n] would be that cube of values over time, a series of cubes of data, Just like the original 1D array. So, the 5th Dimension would be a series of objects over time. Dimension 6 would be those objects over time in different dimensions(?). What would 7 be? What about 8? Any thoughts?

I don't think you will ever need to use more then 3d arrays. Most people find it difficult to imagine 4D or 5D.

I read a description in a book once. It went:

Imagine a one dimensional universe, any creatures living in it can only move forward or back and never travel past each other.

Then imagine a two dimensional universe, any creatures living in this would be freely able to travel forward and back, up and down.
They would be able to move past each other (over and under) and would see each other as a line.

Imagine if one of us in our three dimensional world were to pick an object out of the 2D world and replace it
somewhere else. Where would the 2D creatures think it had gone?

Now imagine if an object was plucked out of our world by a 4D creature and then replaced somewhere else.

Where did it go?

It is hard to imagine what this 4D world is like - this is a fourth dimension in space, not time.

I suppose that if you can get your head around this, then you can continue to add as many dimensions as you like.

I dont think i would ever want to use a 4 or 5D array, i just think its an interesting way of thinking about it =).
