Somewhere between 136 and 138 the reciprocal value of a
constant is located, which symbol is alpha: the fine structure
constant.

It is used to shorten an expression, which appears in the formula
for electron radii in Bohr's model of atoms.

A theory of 6-dimensional space-time gives an approximation for
aplha as 4 pi*pi*pi*pi*pi / 9 (136.0087488...) resulting from a
special formula for the charge of the electron.

The real value for the electron charge is slightly less and therefore
the real value for alpha slightly more than its theoretical value,
because of vacuum polarization (of electron-positron pairs around
the electron, which appear and annihilate in a time given by
uncertainty-principle t*E<h'). The exact value is then
137.035987....

A value for alpha for computations is 1/137.

For those with a pocket calculator:

formula for charge:
q ~ 1/pi² sqrt(h/2pi sqrt(eps(0)/mu(0)))

where -3q is the charge of the electron
(2q of up-quark, -q of down-quark)

with these constants

h/2pi = 1.0546 E-34 Js (Planks constant)
eps(0) = 8.8542 E-12 C/Vm (dielectric constant)
mu(0) = 1.2566 E-06 Vs/Am (magnetic constant)

gives

e ~ 1.60825 Coulomb
(charge 3q of electron with formuala)

Measured value:
e = 1.60219 Coulomb

formula for alpha:

alpha = e²/(4 pi eps(zero) h/2pi c )
using c = 1/sqrt(eps(vacuum)*mu(vacuum))
substiting e by above formula
~ 3*3/(pi²*pi²) /4pi
= 9/4pi^5
