For, the past few days, we've been discussing 3-dimensional graphing. Mrs. Walters often talks of 3-D, 2-D, and 1-D objects. This has often caused my mind to wander. (often causing me to do poorly on my assignments) So I was thinking are all these objects phisically possible? I'm sure that 3-D objects are possible, after all, we live in a 3-dimensional world. But are 2-D objects phisically possible. It appears that they arent't phisically possible, but are posible in some picures and all virtual images. Paper isn't 2-D. I just want to clear this up. Mrs. Walters often refers to paper and drawings as 2-D. They're not. They have a length, width, and heigth. The height may be miniscule, but it cannot be ignored. the drawings too, were created with ink, which exists in 3 dimensions. Now, this got me thinking about whether or not 2 dimensional figures exist at all. i suppose they do, on screens, because the image itself does not take up 3 dimensions in space. The awesome warped space picture I posted has a length and a width, but I don't believe it has a height. I may be wrong, you more technologically advance people may be prove me otherwise. If it turns out that the awesome photo I posted does have a height, then I can't figure any other way a 2-D object could exist in our 3-D world. Now, Mrs. Walters calls points and lines 1 dimensional objects. This is most definetely possible. A point and line both have a length and width, even on a computer screen. I don't believe a 1-D object is, or will ever be possible, ever. Now, to end this blog post with a cool little twist, can anyone think of how a 4-D object may exist? What is 4-D? Maybe an object with a length across time? Would this cause temporal impossibilities? Please leave your thoughts in the comments, I hope this post made you think! Also, please don't tell Mrs. Walters what I said here.

I think that Mrs. Walters will find out. After all Mr. Nasshan found out about our disscussion with Mrs. Chesney

I am soooooooooo happy you talked about the two dimensional impossibilities and I have always gotten so P O'D when people say paper is 2 dimensional. Also that image is not 2 dimensional because a. pixels have depth, and b. you are seeing the light projecting from the screen so it is not the actual dimensions of the pixels but the length, width and height so therefore it is a dimensional impossibility because the light extends for an infinite space. Also the one dimension is all theoretical and is supposed to help describe points and lines, not to classify them. So to answer your question, I don't think there are two dimensional objects, and to answer your question a 4th dimensional object could never exist because the background radiation would collect infinitly, destroying the entire universe. In short, no,

interesting thoughts... I have no idea what a 4th dimensional object would be

It's true. 1 and 2- Dimensional Objects are a spatial Impossibility (because it's impossible for a tangible object to have no height). However, in computer models a lot of objects only have 1 or 2 dimensions (which causes the dreaded Bowtie effect in Modeling). Also, it has been said that there are as many as 11 dimensions (although many physicists say they were simply created as a justification for odd blips in String Theory's mathematical proofs), and if there are, we would probably be unable to percieve them without the use of advanced equipment.
