Me and a few friend had this conversation about dimensions.
See the thing we were talking about is 2d existing in a 3dimensional world.
He said if you have let say there a drawing in a paper then the drawing is 2d.
so he is saying that 2d can exist in our world.
Is it really 2d?
I mean the lead has height width and depth, only a little depth though.
So the drawing is in fact 3d but only appears as 2d.
as you know 2d is only made up of height and width but no depth.
I am not sure but I know a lot of you kirupians are pretty smart I need your opinion.
well, lets talk about universe rather than a single world
Universe is in dimenson…
all the 3d such as X, Y, Z as in a graph… and there is one limit we forget… ie TIME
To what do you relate one object to another… we can say it in bounded limit of X and Y and Z in 3d form which is in terms of an centre. However in Universe nothing is related to nothing cause it goes beyond those 3D… it TIME…
as long as we related any thing …we are bounded by 3d limitations…
I can easily imagine both 0, 1 and 2 dimensions, but i can’t see them… The way I think of them is:
0 = Imagine a point anywhere in the world, but don’t focus on what the point “contains”, just the position it indicates.
1 = Imagine the distance from your house and to the library (or something like that, I don’t care). Don’t focus on the road that leads you there, but just the fact, that the distance between your house and the library exists.
2 = Imagine the area of the floor in your livingroom. Don’t focus on the material the floor itself is made of, but simply the fact, that the space exists.
Does anyone agree with my explanation of the 3 first dimensions?
Yes, I think that’s a great way to explain it.
Points, lines, planes - they are really concepts, mathematical ideals as you described them. Which is why we don’t ever *really *see them. We can approximate them, define them with words and equations, but we aren’t going to find them growing on trees or hiding under rocks.
Yup
