**Fine Structure Constant**

The fine structure - or coupling
- constant is one of the biggest mysteries of physics of
the last decades.

The current descriptions and explanations (according to
the Wikipedia
page on the subject and various findings and interpretations)
are strictly empirical. There are at least seven possible
physical
interpretations on this wikipedia page for the physical
meaning of the fine structure constant.

The approach of the circulating electromagnetic
wave model of the electron on this website (submitted
for publication) derives
the simple formula for the fine structure constant with
a clear physical concept.

The ratio of the field energy responsible
for the charge to the total particle rest energy is the
dimensionless figure 1/137, which is identical in value
and formula to the fine structure or coupling constant.

The fraction 1/X of the field energy
of the electron that forms the
external charge to the total field energy
can be calculated. The electron is regarded as sphere capacitor
with the stored energy E = 1/2 Q^{2} /C.

.
With the capacity,
the charge Q is

With the values for the de Broglie
frequency ,
the electron radius
determined above and the factor 1/X = 1/137, the electron
charge is calculated correctly to 1.603 10^{-19}
C. The dimensionless fraction 1/X equals the fine structure
constant .

If the known formula of
is inserted into the above equation, the product inside
the root equals to
and Q = e. The coupling constant
perfectly confirms the current model.

Above approach is regarded the quantum
realistic origin and meaning of the coupling - or fine structure
constant as the ratio of the electric field energy forming
the charge of the electron to the total field energy .

or on the quark.

This physical approach for the origin of the fine structure
constant is simple and gives a definition that does not
rely on the interaction between a photon and the electron.

From the spin the** electric
charge** and the electron radius can be calculated.
