Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - To color a given map we first find its related map with the most mutual adjacency and color it by only four colors, then we trace back. For a large even number there are a large number of pairs of odd numbers sum of the members of each being the even number. We eliminate those pairs that none of the members of each of them is prime and show that number of the remaining pairs is still large. Process of proof shows that there can be no drop to zero in the function of number of the mentioned prime pairs. It is shown that we can take all numbers to odd bases such that we require only about half of the digits required in the current method provided that we introduce negative mark for each digit. Most probably this method will have various applications in computer technology. It is shown that the wave equation cannot be solved for the general spreading of cylindrical wave using the method of separation of variables. But, an equation is presented in case of its solving the above act will have occurred. Also, using this equation, the above-mentioned general spreading of the cylindrical wave for large distances is obtained which contrary to what is believed consists of arbitrary functions.

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - There is a uniqueness theorem, other than one of electrostatic potential, that states charges given to a constant configuration of conductors take a unique distribution. Using it we get coefficients of potential. A simple carelessness has caused it is deemed that electrostatic potential is half of volume integration over D.E, while in it E must be replaced by a part of it that is the electrostatic field arising only from the external charges not also from the polarization charges. Capacitor's capacitance does not depend on the dielectric used in it and depends only on the configuration of its conductors. We correct some widespread current mistakes in these respects. Dielectric polarization in the capacitor of a circuit causes attraction of more charges onto the capacitor. So, we must consider capacitor's dielectric as a source of potential not changer of capacitance. These two are not the same, eg it is shown that contrary to what is believed, resonance frequency of a circuit of RLC will increase by inserting dielectric into the capacitor, for which a report of a performed experiment is presented. What is calculated as K (dielectric constant) is in fact 2-(1/K).

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Cohesion pressure in liquid due to inward intermolecular force on surface molecules, not surface tension, causes minimization of liquid surface. Surface tension isn't what causes horizontal wire sliding on two limbs of a U-shaped wire to be in equilibrium in any position. Incorrectness of current relations for pressure differences between inside and outside of a bubble and one related to a solid drop is proven. In surface evaporation liquid increases the potential energy of its molecules by taking heat while their kinetic energies remain unchanged. Gas temperature decreases due to surface evaporation while some net heat is transferred from gas to liquid. So if gas temperature is only a little lower than liquid temperature, some net heat will be still transferred from gas to liquid due to surface evaporation and finally gas and liquid will be isothermal in a temperature lower than the initial temperature. This violates the 2nd law of thermodynamics. An equation is presented in case of its solving wave equation can be solved for general spreading of cylindrical wave. Using it, general spreading of cylindrical wave for large distances is obtained which consists of arbitrary functions.

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - We prove as Newton s 3rd law holds in static aspects of Electromagnetism it holds also in dynamic aspects of it. Force on current-carrying wire in external magnetic field and force on magnetic needle in Oersted s experiment are action-reaction forces. By considering point magnetic charges, mutual effects of electric and magnetic charges on themselves and on each other are presented in the forms of vectorial relations. Using these relations, incorrectness of a usual manner which eventually leads to the deviation from the classical physics and to the rejection of the Galilean transformations and to the resort to the special relativity is proven. Almost all the fundamental relations in the current electromagnetic theory are rewritten in new forms by using the presented fundamental vectorial relations. The way electromagnetic wave propagates through tiny magnetic and electric dipoles is easily explained by using the mentioned relations and obtaining the new form of Maxwell s equations and deducing the wave equations from them. Fresnel coefficients are obtained in their new forms. In this new approach, reflectance and transmittance are introduced the sum of which is identical with one.

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - We both proceed to current mistakes and present new theories in E&M. Potential difference between two conductors of a capacitor is two times more than potential difference between two poles of the battery which has charged it; we see influence of this in the experiments performed for determination of charge and mass of electron. Existence of conduction current isn't because of existence of any electric field in conductor and the linear relation J = gE cannot be valid. Relaxation time and drift velocity are independent of charge and mass. Action mechanism of transistor is explained and a hydrodynamical analogue for it is introduced. In a gradient of magnetic field magnetic dipoles of air are attracted toward the region of intense field and create an air pressed pad there causing levitation in diamagnetism. Electrons get freed from hot core of Earth accompany it in revolving around stationary liquid core and so create a big magnet in it. Probably electron doesn t have a size so small compared with the dimensions of a molecule. We must take into account role of air pressure difference created at two sides of each of two parallel current-carrying wires in their repulsion or attraction.

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - We have tried to show the necessity to search for any existent classical solution to solve any physical problem before trying to use Quantum and Relativity. We have used this method to verify carefully some important events in Physics that the claimed inability of Classical Physics to explain them was the origin of advent of Modern Physics. Important phenomena currently regarded totally as supporters of Quantum and Relativity Physics's are justified in Classical Physics. These are: photoelectric effect, Compton effect (as a Doppler effect), Stertn-Gerlach experiment, Franck-Hertz experiment, wave-like behavior of electron beams, presentation of the electromagnetic theory without Special Relativity (and without breach of Newton's 3rd law), optical justification of deviation of stars light by Sun. Also correction of some serious shortcomings in them are presented, like: proving invalidity of the Planck's derivation of E=h , justification of the Hall effect (without supposition of hole), verification of the concept of photon (pressure), proving that stellar aberration doesn't contradict ether drag, showing the invalidity of distinguishing between inertial and gravitational masses.
