1   Point In Geometry

1.1   In geometry, topology and to other such parallel areas of mathematics, point is the simplest objects that other objects can be defined. For example a line is an infinite set of points.

1.2   Point determines the position on a two-dimensional map page and in the three-dimensional volume.

.

1.3  The general definition of a point does not take a stand on what the point is in itself. If the point is a human, the geometric definition probably would be; Man is the smallest set to other sets of objects to be defined, such as the nation. The above definitions do not describe the point any more than a human being. The nature of the current physics and geometry appears in the point definition. Instead, we can look at the essence of a point and leave the lines, and other patterns later.

1.4   At first, can say the point to describe infinity. It is small in size and compared to outside space infinite. Point is responsible for division by zero, which both answers are correct. 


0/0 = 0        0/0 = 1


Generally thought point and zero (0) have the likeness, the objects containing anything.

3.   Euclide' Elements

The first few definitions

Definition 1       A point is that which has no part

Definiton 2         A line is a breadthless length 

Definition 3        The Extremities of a line are points

Definition 4      A straight line is a line which lies evenly with the points on itself

3.   EP-Calculation

tuotearvokayra.jpgIn EP-calculation the importance of a point is a geometrical description of zero-dimensionality and point also describes the location of a phenomenon on a value curve. 

Points are determined in one-dimensionality, in other words the distance between them.

Points are in the value space, but their location of view of the phenomenon is not relevant. The phenomena do not ask for the location coordinates. 

4.   History

4.1   Euclid defined point in his book The Elements, saying that " the point is something that can not be divided ". The idea is ​​reflecting the Demokritos idea of ​​the atom, the smallest part of a substance, which could no longer be shared.

4.2  The ancient geometry were measured points and the distances used to detect the coordinates of the points in place. The point of the place was considered an unambiguous only if it could be linked to the fixed points of a sufficient number of distance allows .

4.2   EP-calculation principle has much the same way as the Greeks had with a well-known places. These places determined the location of one point. This is comparable to EP-calculation well-known data about the value. Conversely in EP-calculation at least one well-known point determines the other points on the curve and even separate graphs.
