The molecules of the reflecting surface are sources of Huygens' wavelets
which make the reflected wavefront. These molecules can be nonplanar to
the extent of a fraction of the wavelength while yet there exists practically
reflected plane wavefront.

In a primary manner it is shown that if a body is stationary the torque
exerted on it is zero, while at present avoiding the analytical proof of this
theorem, this theorem is presented to the student unprovenly and almost
as an axiom.

In surface evaporation the liquid increases the potential energy of
its molecules by taking heat while their kinetic energies remain unchanged.
In such state the molecules are in the form of a gas (vapor).
We know that in an isothermal system of a liquid and a gas adjacent to
it, the temperature of the gas decreases due to the surface evaporation
while some net heat is transferred from the gas to the liquid. So, if the
temperature of the gas is lower than the temperature of the liquid only
in a sufficiently small extent, some net heat will be still transferred
from the gas to the liquid due to the surface evaporation and finally
the gas and liquid (and vapor) will be isothermal (in a temperature
lower than the initial temperature). This matter violates the Clausius
(or refrigerator) statement of the second law of thermodynamics.

It is shown that surface tension is not the reason causing minimization
of the surface of a liquid pile. It is shown that there exists a pressure inside
the liquid arising from the inward intermolecular resultant force on the
surface molecules exerted by the liquid molecules adjacent to the surface.
We call it as cohesion pressure. A method is presented for measuring
the intermolecular attraction which will be also a means for testing the
theory in comparison with the current theory of surface tension. It is
proven that the surface tension is not what causes the horizontal wire
sliding on the two limbs of a U-shaped wire to be in equilibrium in any
position when a liquid film forms the area of the U-shaped wire. In a
sure manner, incorrectness of the current relation Δp = 4
γ/R, for the
pressure difference between inside and outside of a bubble having radius
R, and Δp = 4
γ/R, for the one related to a solid drop having radius
R, is proven. It is shown that the adhesion reduces the pressure inside
the liquid, because a part of the liquid weight is sustained by the walls
of the container. The mechanism of capillarity is discussed in detail in
terms of intermolecular attraction and cohesion pressure. Dependence of
rise altitude on depth of dipping and dependence of fall depth on depth
of dipping are properties in capillarity; this is predicted by the theory
presented in this paper and not by the theory of surface tension, and then
can be a practical test for the theory.

It is not necessary to distinguish between inertial and gravitational
masses believing that the nature has chosen them quite proportional to
each other by chance, and not necessary to believe that the nature by
chance has chosen the power of distance in inverse-square forces exactly
equal to two, and not necessary that in trying to define mass (and force)
to become involved in a vicious circle using presupposition of existence
of inertial reference frame which itself requires pre-definition of mass.
Newton's laws of motion are rewritten in a logical manner. Some primary
models are presented as guides for discovering the essence of known
forces. A model for justifying the force between two electric and magnetic
charges, moving relative to each other, is presented. In fact energy has
only one form: kinetic energy. The law of action-reaction holds completely
and undoubtedly only during the direct collisions of particles.

Action mechanism of a conductor is presented in a simple manner. It
is proven that this is not the charges themselves that are distributed in
the conductor but their substitutes do this act. Also we conclude that
probably the electron doesn't have a size so small compared with the
dimensions of a molecule. In a discussion relating directly to the subject
of surface tension we see why a net negative charge in a conductor cannot
leave it.

A perfect comparison between a closed circuit of water current and a
closed circuit of electric current is made and Ohm's law is obtained in this
manner and it is shown that, contrary to the current belief, existence of
conduction current is not because of the existence of any electric field in
the conductor, and the linear relation J = gE cannot be valid. The relaxation
time (necessary for the current to reach its final speed) and the final
speed (drift velocity) of the current are obtained in the above-mentioned
manner, and it is shown that, contrary to what is believed at present, both
of them are independent of the chosen standard unit charge (eg electron
charge or coulomb) and its mass. It is also shown that, contrary to the
current belief, alternating current is steady. We also prove the existence
of a kind of resistance arising from the configuration of the circuit. Action
mechanism of transistor is explained and a hydrodynamical analogue for
it is introduced: both confirming the material presented earlier.

It is shown that as Newton's third law holds in static discussions of
Electromagnetism it holds also in dynamic discussions of it, ie where
the motion of electric charge in the magnetic field arising from the
magnetic static (or magnetostatic) poles is under consideration. In
addition, it is shown that in this recent case the forces of action and
reaction are not collinear. In other words as we know there is some
force exerted on a current-carrying wire in the magnetic field of a
magnet. It is shown that this magnet is in fact the same enlarged
magnetic needle in Oersted's experiment, and then there exists also
some force exerted on the magnet due to the electric current in the
wire. These two action and reaction forces are in opposite directions
but are not collinear.

Density of lines of the magnetodynamic field arising from two parallel
currents is more in the regions out of the distance between the
two wires and then the molecular magnetic dipoles of air are pulled toward
these regions and create a bigger pressure there which causes the
two wires to be pushed (or to be attracted) toward each other. A similar
reasoning applied conversely to two antiparallel currents justifies
their repulsion arising from the created air pressure difference. Thus,
most probably, railgun will not work very well in the absence of the air.
