In physics and mathematics, the size of a mathematical space (or object) is randomly defined as the minimum number of links needed to clarify any point within it. So a line is the size of one (1D) because only one link is needed to specify a point on it - for example, point 5 on the number line. A plane-like area or cylinder or globe has two dimensions (2D) because two coordinates are needed to determine a point in it -
for example, both latitude and longitude are needed to locate a point in space. circular area. The inside of the cube, cylinder or globe has a three-dimensional (3D) dimension because three links are needed to determine the point between these spaces. In ancient mechanics, space and time are separate categories and refer to space and time. That concept of the earth is a four-dimensional force but not one that has been found to explain the magnetic field. The 4 dimensional space (4D) spacecraft includes events that are not fully spelled out locally and temporarily, but are known to be related to the spectator's movement. Minkowski's space first measures the universe without gravity;
The pseudo-Riemannian manifolds of general relativity defines space time and matter and gravity. 10 sizes are used to describe superstring theory (6D hyperspace + 4D), 11 sizes can explain gravity and M theory (7D hyperspace + 4D), and the state of quantum mechanics is a workplace with infinite magnitude . The concept of greatness is not limited to material things. Higher size spaces often appear in mathematics and science. It may be parameter spaces or stop spaces such as Lagrangian or Hamiltonian mechanics; these are invisible, independent spaces in our environment.
