Lobachevsky Geometry and Einstein Kinematics

A.D. Gladun

Moscow Institute of Physics and Technology (State University, Russia)

 

Einstein kinematics, like computer and spark track chamber, is a labour tool, a working instrument of the high energy physics and technology. It is shown that applying the apparatus of the relativistic mechanics we deal in essence with Lobachevsky geometry. This circumstance opens wide possibilities of a practical use of the non-Euclidean geometry in calculations of the scattering processes.

 

 

Simple Illustration of a Principle of a Minimum of Manufacture of an Entropy (Principle of a Minimum Integrated Dissipation)

V.S. Bulygin

Moscow State Technologic University "Stankin"

 

With the help of a principle of a minimum integrated dissipation deduced from a principle of a minimum of manufacture of an entropy, the time dependence of a charging current in a RC-chain is obtained.

Introduction to Discipline

V.V. Chernyshev

Military Aviation Technical University,

Planetnaya 3, Moscow

Version of introductory lecture on physics for technical institute is proposed. It is discussed the aims and problems of this discipline and also the general requirements to technical institute students in context with physics study. Discipline structure has been determined of view its minimal sufficiency. Some classification scheme of the different physical objects and phenomena study is considered. Perhaps it may be useful under discipline structure forming. The main models of objects and phenomena in mechanics are described.

 

Radiofrequency Electron Paramagnetic Resonance

Spectrometer for Laboratory Training

Moscow Institute of Physics and Technology (State University)

The work describes the design and operation principle of the EPR-spectrometer working in the range of 100-200 MHz. The device is reliable and makes it possible to determine the electron g-factor, the time and character of relaxation (the line width of EPR and its temperature dependence).

The laboratory project is offered for physical practical work with studying parameters of free damped vibrations (frequency, damping factor, logarithmic decrement, time of relaxation, quality and internal friction) with following calculation of material characteristics is damping ability and shear modulus.

 

Non-traditional Effects of Electrostatic Interaction of Charged Conducting Balls

V.A. Saranin, V.G. Korolenko

State Pedagogical Institute, Glazov

 

Such non-traditional coupling effects of charged conducting balls, as their interattraction are considered in case of one sign of charges, asymptotical behavior of force, electrostatic energy on small distances between balls, amplification of an internal field of one sphere at the expense of reallocation of own charges and charges of other sphere.

The invariant behavior of force of interaction of balls under condition of equality of the ratios of charges of balls and quadrates of their radii is placed. In this case it is a repulsive force for all distances between balls. At other, an arbitrary ratio of radiuses and charges at coming together of balls the force of their repulsion is replaced by attractive force.

Also invariant behavior is watched and for field intensity on a surface of balls, but only under condition of equality of the ratios of charges and radiuses (that is under condition of an equality in capabilities of balls). In this case field intensity monotonically decreases up to null at coming together of balls.

Using the experimental data of other writers, numerically are retrieved field intensity of breakdown of an air interval between balls. The outcomes of calculations are shown in one figure and allow concluding, that the least value of field intensity of breakdown at standard conditions is the value 26 kV/cm.

 

Standard Calculations in General Physics Course

Voronezh Institute of Internal Affair Ministry of Russia

Standard calculations application in physics training course is described. The main aim of standard calculations carrying out is considered to be students' original work development problems solving or physics instruments operating improvement, skills checking and examination.

 

Gravitational Interaction of Spherical Bodies which are Taking Place in Infinite Environment

E-mail: plazma@pi.ccl.ru 

 

The analysis of the equation for force of gravitational interaction of two spherical bodies which are taking place in infinite environment with density r0 is carried out. In a limiting case, when the density of bodies are much greater r0, the equation passes in the Newton law of gravitation.

Various Internet bases of experimental data have created recently in the field of nuclear physics and physics of elementary particles. These bases enable to train students using advanced experimental data to teach them to employ methods of scientific research, which are essential in the word of international cooperation.

 

The ˇomputer Model as Physical Demonstration

In this article we discuss the employment of computer experiments in physical education, particularly the employment of this experiments for demonstration of physical phenomena. We describe our computer demonstration models.

 

Computer Support of Lecture and School Lesson of Physics: an Electromagnetic Induction

The Ural State Technical University, Liceum ? 130

 

Life demonstration experiment is to be an obligatory component of the physics lecture and serves important didactical functions. Computer graphics may be quite useful directly for instructor during explanation at the stage of building an appropriate model of the phenomena under consideration. Now, after the first publication we have a technology of physics lecture accompaniment. The equipment for the technology includes PC and a screen in class. Animated graphics is a key component of the technology as usual. Some ideas of the software are discussed by the example of topic "Electromagnetic induction. Self-induction".

The article presents methods of physics teaching in educational process with use of modern computer technologies. The reasons of the students' interest decrease in learning natural science subjects are analyzed. The ways of increasing students' knowledge level and their interest in the subject with the help of computer teaching programs are suggested in the article. The pedagogical experiment of teaching physics with the use of computer simulation in the FESU (Far Eastern State University) College is described.

According to the results of regional subject competitions and psychologico-pedagogical tests of schoolchildren the article establishes a fact that the all-Russian Olympiad of schoolchildren functions in general as a program using an extensive way of choice and search of talented children which corresponds to the regime of psychological discomfort of the tested.

A new scheme approbation of holding subject competitions, which proposes a 2-level set of tasks, a 2-dimension system of evaluation and participants distribution in a competition showing two indices of priorities is summed up in the article.

 

The Untraditional Approaches to physics training at preparation faculty

The form of preparation on physics in technical academy for potential students, handing over and not handing over physics on entrance examinations are discussed. The training is conducted at preparation faculty of VSTA. It provides increase of a level of initial knowledge on physics, improvement of progress of the students. The interrogatory results "Preparation to academy by eyes of the students" are analyzed.

Methodic Recommendation to Practical Study

Military Aviation Technical University,

Planetnaya 3, Moscow

This recommendation introduces to geochemistry cycles problems in view of global physical and chemical processes. Under certain conditions the changes of some these processes parameters may provoke catastrophe irreversible consequences in the biosphere. In this point of view it make sense to include the present practical study in the discipline of natural sciences cycle.
