A Wave-Based Polishing Theory

Authors: Hamid V. Ansari
Comments: 3 pages

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.

"Proposition for Performing a Series of Important Electromagnetic Experiments" and "Why Two Parallel Currents Exert Force on Each Other"

Authors: Hamid V. Ansari
Comments: 6 pages

The real causes of force existent between two current-carrying wires are searched. Some electromagnetic experiments are proposed to verify these causes and other similar material.

Primary Proof that the Torque Exerted on a Stationary Body is Zero

Authors: Hamid V. Ansari
Comments: 3 pages

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.

Why Evaporation Causes Coldness; a Challenge to the Second Law of Thermodynamics

Authors: Hamid V. Ansari
Comments: 11 pages

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.

A Deliberation on the Surface Tension Theory

Authors: Hamid V. Ansari
Comments: 16 pages

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.

A Critique of the Definitions of Mass and Force

Authors: Hamid V. Ansari
Comments: 18 pages

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.

Classical Analysis of the Electric Conductivity

Authors: Hamid V. Ansari
Comments: 8 pages

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.

Electric Current Similar to Water Current

Authors: Hamid V. Ansari
Comments: 20 pages

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.

A Deliberation on the Limits of the Validity of Newton's Third Law in Electromagnetism

Authors: Hamid V. Ansari
Comments: 7 pages

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.

Role of Air Pressure in the Force Between Currents

Authors: Hamid V. Ansari
Comments: 9 pages

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.
