Dimensions and types

Introduction:
     The dimension of a space or object is defined as the minimum number of coordinates needed to specify each point within required object.

• Thus a line has a one dimension because only one coordinate is needed to specify a point on their object.
• A surface such as a plane, the surface of a cylinder, 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 its longitude.
• Inside the cube, a cylinder or a sphere is three-dimensional because three co-ordinates are needed to locate a point within these spaces.                                                                                                                                                                                                                  

      The theory of dimension is not answerable to physical objects. High-dimensional spaces will   happen in mathematics and the sciences for lots of reason, frequently as arrangement spaces such as in Lagrangian or Hamiltonian mechanics; these are theoretical spaces, independent of the physical space we live in.  So we need 4-dimensional universal relativity for High –dimension.

Types of Dimensions:

There are 3 types of dimensions,

•  One dimension (1D)-It enclose only lengths of object.

• Two dimension(2D)-It enclose length and breadth.

• Three dimension(3D)-It encloselength, height and depth.
