...What is Real Since the beginning of higher thought there has always been an internal struggle within the very depths of man that wondered “What is Real”. For centuries all men have tried to define and analyze this for many different reasons, to predict the future, to know where we came from, to manipulate and control. After all the time that man has been on Earth many different ideas and theories have developed on this topic but this still has been one of the most universally debatable issues. Reality is dependent on each individuals own interpretation of what is real in terms of our sensory experience, personal perceptions, and own individualistic beliefs. Edwin Abbott wrote a great analogy about our dimensional experience in Flatland: A Romance of Many Dimensions. Many subjects are approached in this book but the most interesting was the concept of dimensions. He starts off describing that we live and apply logic in dimensions; the first dimension consists of points that can produce a single line, the points live in the first dimension and therefore cannot grasp the perception of the next dimension. The second dimension consists of moving lines which turns into shapes along two axis’, this dimension can fully understand the first dimension but yet again the next dimension is inconceivable. In the third dimension the same idea is applied, the shapes formed along the second dimension are moved and twisted into, as we perceive it, three dimensional shapes that are multisided...

...------------------------------------------------- Dimension From Wikipedia, the free encyclopedia "0d" redirects here. For 0D, see 0d (disambiguation). For other uses, see Dimension (disambiguation). From left to right, the square, the cube, and the tesseract. The square is bounded by 1-dimensional lines, the cube by 2-dimensional areas, and the tesseract by 3-dimensional volumes. A projection of the cube is given since it is viewed on a two-dimensional screen. The same applies to the tesseract, which additionally can only be shown as a projection even in three-dimensional space. A diagram showing the first four spatial dimensions. In physics and mathematics, the dimension of a space or object is informally defined as the minimum number of coordinates needed to specify any point within it.[1][2] Thus a line has a dimension of one because only one coordinate is needed to specify a point on it (for example, the point at 5 on a number line). A surface such as aplane or the surface of a cylinder or sphere has a dimension of two because two coordinates are needed to specify a point on it (for example, to locate a point on the surface of a sphere you need both its latitude and itslongitude). The inside of a cube, a cylinder or a sphere is three-dimensional because three co-ordinates are needed to locate a point within these spaces. In physical terms, dimension refers to the constituent structure of all space (cf. volume) and its position in time (perceived as a scalar dimension...
