Physical meaning of base of natural logarithm e
There is number “e” that is called “base of natural logarithm” mathematically.
ｅ ＝ lim (1+1/n)^n ( n →∞ )
＝ 2.718  
this is definition of e, and this e is used in many theories of mathematics
and physics. Therefore, importance of the number will be very high.
But nobody could explain how this number was fitted into natural phenomenon,
and why “e” was needed in our world. But it can be explained by introduction
of “Five dimension theory”.
As is understood by definitional equation, “e” is expressed as the product
of (1+infinitesimal) and infinity. Though the idea, 1+infinitesimal, is
subtle, if one is regarded as largeness, the other can be regarded as point.
In “Five Dimension Theory”, combination of point and largeness is necessary in order to generate recognition of space, recognition of largeness. Seeing largeness from point, largeness can be felt, on the other hand, seeing point from largeness, point can be recognized.
Infinite continuity of this operation is formation factor of recognition
of space. Point and largeness in this case is combination of “1 and infinitesimal”
mathematically. To repeat it infinitely is expressed as infinite product
mathematically.
Thinking in this way, all existences include “e”. Therefore, it was natural
that “e” appears in mathematical expression of natural phenomenon.
“e” has been used in all aspects of scientific theories without understanding
the meaning of it until now. As essential meaning of “e” can be understood
after “Five dimension” is introduced, understanding of scientific theories
will be dramatically progressed
