Basis of the Theory of Inter-subject Connections T.N. Gnitetskaya Far East State University, Vladivostok; The basis of the theory of inter-subject connections is developed. The principles, models, theories, laws, and concepts are presented in the corresponding groups. The definition of inter-subject connections, as a connection realized through elements of a group. This connection is shown in several objects of studying. The concept of a unit is established, and is described as a characteristic of an element of a group in relation to some element of structure, length of connection, force of connection, and force of connection of a structural element with the structure of a general physics course. For one of the structures of a traditional course of general physics, the classification of elements of a group of laws by their importance is given as an example. The method allows on a basis of intersubjects connections not only to optimize but also to carry out the structurization of a general physics course.
V.I. Nikolaev M.V. Lomonosov Moscow State University, Faculty of Physics The construction of the so-called thermodynamical square is described which is used in five various mnemonic rules. With the help of these rules, it is easy to write down several sets of one-type formulae which are widely used in thermodynamics. These formulae contain the thermodynamical potentials, or their natural variables, or those and others at the same time. Cases are considered in which the potentials depend on either two or three natural variables.
Refinement of the University Physics Course A.Yu. Gryaznov Moscow State University, Faculty of Physics A version of the refinement of the university physics course is proposed based on Kant's methodological apriorism. The article deals with the problems concerning the definition of inertial frame of reference and the relationship between deductive and inductive methods in the university physics course.

Entropy as a Measure of the Chaotic State of a Thermodynamic System A.A. Shartz Moscow State Technological University "STANKIN" The article offers a new method teaching the concept of entropy in technical universities. The main emphasis is on the qualitative aspect of the entropy concept and on more precise definitions of using terminology.
Laboratory Project: "Designing a Meter of Temperature" S.á. Kazantchev, á.H. ábdrahmanova, F.í. Samigullin ëÁzan State Technological University A project for the physics laboratory course on "Electricity" is discussed. It relates to choosing optimal parameters of the scheme, intended for compensating for environmental temperature influence on thermocouple measurements . The project is done on PC.

The article considers methodical questions, that are connected with the experimental study of solitons of the Korteweg-de Vries type in nonlinear transmission lines. The following sections of the article describe the active model, the short theory of solitons KdV in discrete transmission line of the type low frequencies filter with nonlinear capacities (varactors), description of the model, including a system of automatic indication, and exercises on formation and interaction of solitons, and other quantitative features.
Laboratory Study on the Research of Interference of Waves with Circular Polarizations N.Ya. Molotkov, V.V. Shal'nev, N.V. Khvostov, V.B. Divak Tambov State University In scientific and educational literature on wave optics it is almost impossible to find the description of experiments of Arago (1824), as well as the theory of interference of light waves with circular polarizations. Undoubtedly, at the closer examination of wave optics in university level, these questions should be given some attention, which will allow to expand the knowledge of students about the phenomena of interference.
Non-Maxwell Distribution Functions and Their Study in General Physics Labs P.S. Bulkin, G.A. Mironova Moscow State University, Physics Department In a practical work of the Physics Department of Moscow State University, a device for the measurement of energy distribution functions of electrons in multigrid lamp is assembled. Thermal electrons coming from the cathode are exposed to the influence of a spatial charge, contact difference of potentials, and other factors. The measurements are conducted by a method of detaining potential. This method not only allows to receive functions of distribution at various spatial charges, but also to estimate the size of a potential barrier at the cathode, temperature, average energy, and average concentration of thermal electrons.

Computer Experiments as a Tool of Activating the Learning Process of Students T.V. Kotyrlo, I.V. Belitsyn, A.A. Vikharev I.I. Polzunov Altay State Technical University The computer experiment has one big advantage in comparison to real experiment. It essentially saves time, because the preparation of the experiment only consists of initial data input in the computer. The real physical experiment, which previously was not possible because of its complexity, can now be replaced by a computer experiment with appropriate support of computer resources. The computer experiment, as a method of learning, has a large pedagogical potential.
