Is anything 2d?

Is anything actually "2 deminsional"? I mean think about it. A drawing on a piece of paper may look like it's flat and has no deminson, but paper takes up space, and has a thickness. Any object in this world is 3D. The Google definition says 2D objects only have height and width, but no depth. Paper is 3D, you feel it between your fingers. It's thin, yes, but so is aluminum foil, and you wouldn't say that is 2D... I'm confused.

A movie projected on a flat white surface is 2d

A movie projected is only air though. It's just light and colors. That's like saying a rainbow is 2d

In life, it's usually best not to marry yourself to ideas and then be forced to argue absurdities when presented with ideas that counter yours.

That was a bit harsh.

a rainbow is actually 3D, it's a cone (with an inverted tip)
and "A movie projected is only air" wtf?
1 the_fake_slim_shady- 2018-02-02
A movie projected is air and light. You can run through it. It's not an object. It's light making pictures on a surface, same as a flashlight. Light is not 2d.

You're either high or completely dense...

Shadows are 2d representations of a 3d object.
Why is this a conspiracy.
1 XavierSimmons 2018-02-02
Shadows aren't a thing. The term refers to areas of a 3d body that are reflecting less light than other areas. Shadows aren't 2d, they are darker areas of a 3d object(s).

Claire Danes chest is pretty flat. I'd say it's 2D but more like 2As.

But when people refer to a 2d shape, they are most likely referring to something on a piece of paper. Which is 3d. Shadows are also just the absence of light, and air. It's not a solid, therefore it can't be considered 2d either.

Well I don't think there is anything that's absolutely 2D apart from the above mentioned movie projection and shadow. I think I see what you mean.
If you draw a shape on a paper you can put it under microscope and see that your pen has left ink on the paper etc... What we call 2D is rather the depiction of an object. Let's say I draw a triangle - that's 2D because you can not hold that specific shape in your hands, can not look behind etc.
So if a car is printed on a paper then the car itself is 2D but not the print itself.

So what makes something 2D then? Is a gas 2D?
1 Frank_Drebin 2018-02-02
2d means it has 2 dimensions. We live in an observable 3 dimensional universe. String theory and some other theoretical physics proposes more dimensions as possible but we can't experiment with anything like that, because the energy needed to observe these "strings" is far beyond our capabilities.
2 dimensional object are generally thought experiments. A square, a circle, a triangle all represented in two dimensional space. obviously a physical square why have some depth too it and be 3 dimensional in our universe. A shadow, projected onto a surface 8s a good example of something 2 dimensional in our universe. The fact that it is just the absence of light is meaningless. you can measure the height and width but it has no additional dimension ( unless you include variations of the surface it's being projected onto) and that makes it two dimensional.
You are getting wrapped around this idea that you want to see a physical object that's 2 dimensional but any molecule/atom will have three dimensions.

I wouldn't think so, it's still made up of molecules. It's so fun to think of where it all ends, or if it ends at all. https://www.youtube.com/watch?v=p9dn-Umr7VU Small world is so underrated!

2D objects are like triangles and squares and shit. Things that are flat. But it's only in your head that it's 2D, if it's on a piece of paper it's 3D, paper has thickness.
1 GranimalSnake 2018-02-02
A piece of paper is a 3d object... each of it's surfaces is 2d... this shit isn't rocket science man.
1 stainless_hardened3 2018-02-02
This is kind of silly. Of course everything in the observable world is 3-D because all we can observe is 3 dimensions. 2-D objects can't exist because matter can't have zero thickness. It's sort of like a perfect sphere can't make contact with a perfect plane because it can only touch on a single point. A point has zero width and height on the plane it is on or zero surface area. However in the observable world a perfect sphere and a perfect plane do not exist.

Graphene is a two dimensional material.

Yes: Shadows.

I recently saw someone say density rather than dimension.. it put a new approach to my thoughts.
1 the_fake_slim_shady- 2018-02-02
2d only exists ideally. Everything we know and see is 3d. Atoms have thickness.
