As a starting position of the statistical physics and thermodynamics, recommended for use is Boltzmann’s formula connecting the entropy with the statistical weight of the system state, as well as his postulate on the equiprobability of microstates of closed equilibrium system. It is due this approach that the students understand the physical sense of the entropy clearer and the basic equations of thermodynamics and statistical physics become to a great extent simpler to develop.

The new model of the university students’ education methods is offered for the independent undertaking different experimental physical studies. The essence of it is concluded in shaping among the trainees generalized ways of the standard cognitive problems decisions with the using of the experiment. The types of the cognitive problems are chosen on the base of the prominent physicist experimental works analysis.

The theory joint electrical charging of two spheres by means of their contact is considered. Two cases are analyses: in time charging spheres are supported at identical potentials and case, when the spheres are isolated, but one previously is charged up to a known charge. Are given the exact decision and decision as a first approximation on number of the electrical images. Is shown, that in the second case already first approach in a quantitative sense gives result close to exact in all range of change of parameters.

Physical Mechanism of Diffusion in Various Media.

248000, Kaluga, Lunacharskogo st., 63 - 9.

Article main objective - to share an operational experience with the students of the high school, who has found the place in educational system of a higher educational institution, meaningly experienced prospects of the future speciality, and in movement to the special knowledge which has put many of personal work and diligence.

Study of Photoelectric Properties of Solar Battery
A.D.Gladun, F.F,Igoshin. Yu.M.Tsipenyuk
Moscow Institute of Physics Technology

The description of the laboratory work for students in the course of general physics is described. The work is developed for study photoelectric properties of the element of solar battery, i.e. to investigate the dependence of photocurrent and photo e.m.f. on wavelength of irradiating light.

Dumbbell Shaped Simplified Oberbeck Pendulum for Experimental Testing of Law for Rotational Motion
G. N. Freiberg

Modification of laboratory work on studying of rotational dynamics of a dumbbell rigid body with variable moment of inertia is considered. The experiment is based on measuring the time needed for rotation of the pendulum on a given angle. The design of the setup allows for enhanced trustworthiness of the results and operational reliability. A variation method of data analysis is proposed.

The Measurement of the Specific Electronic Charge by Means of a Vacuum Diode Thermoelectric Effect

Glazov State Pedagogical Institute of V.G. Korolenko, Udmurt Republic

The use of bending waves in thin resilient plates as a replacement for liquid surface waves in experimental study of mechanical waves has been suggested.

Studying of the Electro-Optic Effects in Liquid Crystals During Practical Work in the General Course of Physics
M.S. Martynov, A.S. Baklagin, V.N. Yushin
Academy of the Federal Guard Service of the Russian Federation, Orel

The article describes the practical work in studying the nonlinear electro-optic effects in nematic liquid crystals.

Simple Demonstrations of the Bias Current Magnetic Field
V.V. Mayer
Glazov State Pedagogical Institute of V.G. Korolenko, Udmurt Republic

The use of flat capacitor made of rectangular plates with standing wave formed along the longer sides is suggested for demonstration of the bias current magnetic field. Magnetic field is visualized by the coil with incandescent lamp, electric field- by the luminescent lamp.


Interactive omputer Laboratory Works on Physics
E.V. Getmanova
Belgorod State Technological University

Interactive computer laboratory works on the physics with use of mathematical system MathCAD are described. Processes of classical mechanics, electrodynamics, quantum physics are modeled in laboratory works. Three-dimensional and two-dimensional graphs of corresponding physical processes as result of computer model are described. Computer laboratory works promote clearer understanding of the physical phenomena, and do physics more attractive to students.

The Physical Bases of the Information Transfer and Reception Using the Liaison Channels
O.M. Alykova

E-mail: kof@aspu.ru

The wide introduction of the information technologies in life demands studying physical bases of the information processing and transfer. In this article the methodic of the physical knowledge allocation is developed what is illustrated on a stage of the information transfer. Also here are presented both the developed and fulfilled installations, the technical devices which evidently show us the higher named processes.
