#18: The number of dimensions we can perceive is the number of dimensions from 1st to 3rd. 1st being defined with length but no width... by which we can infer that the "zero-th" dimension is just a point in space with neither width nor length. Based on the first dimension, we can create a second dimension... giving a length an added width. When coming to our third dimensional world, we already have a length and height or an x and a y coordinate for every given object. We need to add a z for depth because of things. This 3rd dimensional world we in is one where those of us cannot perceive what a fourth dimensional object or fifth dimensional object is even like.
#19: There are five dimensions: the first is a line - 1D. The second is something like a drawing. It's flat, but takes up space on the flat surface - 2D. The third is what most things are... what movie-makers are constantly trying to create - 3D. It's a tangible object, something that you can hold. 4D is something that movie-makers have also said that their movies replicate, though they are wrong. The fourth dimension is time. What movie-makers are saying is 4D is really just 3D. They want to make it sound cooler. The fifth dimension is a tesseract which, according to Madeleine L'Engle is "a wrinkle in time" which is where her famous book got its name. Basically, you squeeze time and space to create a tesseract which, from what I can remember, can take one to alien places and times. Beyond the fifth dimension, some say that there are even more dimensions, although they become so complicated no one really gets it. To us, only the first three dimensions really exist. We can see them so easily. A line is a line is a line -- we know what that is. We see 2D things all the time: in artwork, blueprints, movies, and video games. Likewise, 3D is a natural part of life. All objects are three dimensional. It's nothing new to us. However, time is a concept, an idea. It's not something you can see or touch. Rather it's something you contemplate. We know that time is passing. We count it, we remember times when things were different from when we didn't exist. But it's not like a line or a drawing or an object. Time could be said to not exist at all. You cannot say that a person doesn't exist. It's different with time. It's intangible. A tesseract may or may not exist. We don't know. At this point, we definitely could not perform one, so for now, humans are unable to go beyond three-dimensional.
#20: In math, there are four dimensions. In each new dimension, things go in a new direction. Something with zero dimension is just a point. A point is an infinitely small place in space. Something with one dimension is a line. A line is made up with an infinite amount of infinitely small points. You can measure how long a line segment is, but you can't measure it any other way -- it only has one dimension. Something with two dimensions has both length and width. A shape that you can draw on a piece of paper has two dimensions. You can measure its length and width, but not its height. A plane has infinite length and width. Something with three dimensions has width, length, and height... such as a cube. You can measure these three dimensions. Space is a concept of something with infinite width, length, and height, and it supposedly contains all of the points in existence. The final known dimension is an abstract idea -- time. You cannot measure it with a ruler, but with something that keeps track of time. Something with four dimensions changes as time continues. This brings up the question of "what is time?" Does time exist? Can we go back in time? We, as human beings, cannot help but to ponder these questions that may not ever be answered.
#21: There are only three dimensions: length, width, and height. Dimensions exist only as we see them and not in an emotional way. Emotions exist within the same dimensions as we do. Height is how far something extends upward when placed on the ground. Length and width are size of something measured in two perpendicular lines to their longest point. All objects have three dimensions except images that only have two. Ideas exist as three-dimensional chunks of code in your brain. There are, and always will be, three dimensions.
#22: There are many dimensions, as many as you would like, and they can be anything and contain everything you want. For example, there would be a dimension for hockey in my many dimensions, and there would be a dimension where I could own any car I want and I would have garages just filled with cars. Although there would be dimensions for school, because there have to be dimensions for everything that plays a major role in your life. This brings reality into the dimension world and reminds us of the constants in the words.
Dimensions = what you want + what you need / constants of life
#23: I believe that there are four dimensions. All people and objects are 3-d things that are able to move or be used in some way. Most 2-d items are viewed. For example, reading words from a page is a 2-dimensional act. I do not know what has been proven, but I believe there could be a 4th dimension. As time continues, in the future, I believe there will be numerous amounts of dimensional things. The first dimension is a point, the second is a line, the third is objects or volume, and the fourth is time.
#24: There are two dimensions. One is 2D, like watching a movie. The other is 3D which is everyday life, like ourselves. There may be other dimensions we have not discovered. Heaven and hell may have totally different dimensions.
#25: That we know of, there are only three dimensions. An example of a one-dimensional figure is a straight line. An example of a 2-dimensional figure is a picture on paper. Lastly, an example of a 3-dimensional figure is a human. We know of only 3 dimensional figures, but it could be that there are even more dimensions. Maybe a 4-dimensional figure is somewhere in this universe or in another dimension. Maybe even a 10-dimensional figure. We really just don't know how many dimensions there are.
#26: The physical book itself is obviously 3-dimensional and the text is 2-dimensional. The characters could be 3-dimensional in the sense that they could be real people if they weren't fake and made-up. The author did grow up in the same time period; maybe he knew people like the people in the book. But I don't really know what is meant by dimensions.
#27: Okay, so there would be the dimensions literally according to scientific interpretation. I think dimensions can also be used as a metaphor for exploring layers of meaning in things. It's like if you take the literal interpretation of a story you understand the surface of it. However, if you notice patterns or suggestions or meanings you are penetrating into the dimension of meaning the author creates. I would say you usually have to go down layer by layer of understanding to get to the deepest or truest meaning. This means that you have to understand the different top layers of the story to put it all together.
[Above diagram: 1st dimension: literal meaning: "The car won the battle;" square surface; 2nd dimension: "Cat worked hard. Cat was brave;" layers of cube; 3rd dimension: "To win a victory takes bravery and hard work;" cube; 4th dimension: "Cube becomes idea in head;" Apply the understanding of the meaning to use in your own life or to help you understand something else.]
5th dimension: If you can evaluate the author's messages in the book, and use your own experiences to critique them, i.e. you already know enough about what they are trying to say enough to agree/disagree.
#28: Realistically, there are three dimensions in how literal an object can be seen. However, when you think about how one can perceive something, the dimensions can be defined differently. You can see something/someone as unimportant and not pay attention to it, in which case your reception would be one-dimensional. If you see something or someone as how it appears to be, and observe its outer characteristics (if regarding a person, then their outward identity and appearance), then your perception is two-dimensional. If you see the subject as more than just its outer appearance and actually search for deeper meaning within it or understand who it truly is (internal identity), you have a three-dimensional perception of it. Obtaining a three-dimensional perception is very difficult and would involve a great deal of observation of the subject until it is very familiar to you. In dealing with a person, you would need to know background information about him and his inner feelings to truly understand him.
The fourth dimension of time can be achieved after knowing that objects or person for a really long time and coming to a deeper level of understanding of and connection with it. Only then can you perceive this thing four-dimensionally.
