Ten general principles for solution tasks on physics are discussed. The idea is founded that, being taken together, these principles create the system base for analysis of situations in which the laws of physics play the role of the main tool for achievement the required aim. Methodical aspects of using these principles in teaching process on general physics are considered. All the main statements are illustrated by examples.
The paper describes the experience of compiling multi-media version of the specialized course for students of the Physics Department of M.V. Lomonosov Moscow State University "Introduction to the Physics of Lasers". The baseline of the course is a sound track of recorded lecturer's presentation for live audience. Then the video frames with formulae, figures, comments etc. are added by means of Macromedia Flash software package. The methodological and technological aspects of creating such course are discussed.
Computer text book "Nonlinear Waves and Nonlinear Optics" is based on lecture
course for senior students of the Physics Department and for students of International
Laser Center of MSU. Technological base for compiling computer aided courses
has been developed in the Research Computing Center of MSU. It is characterized
by robust representing of the complex physical and mathematical texts with
formulae, ability to include graphics, audio and video clips, and computer
animation of 2D and 3D objects, mathematically correct drawing of plots with
interactively changed parameters, information subsystems with hypertext links.
Training of students on laser technology requires different methods. Theoretical course cannot provide development of creative skills of student, which is necessary to solve real technological or research tasks. Therefore using problems in education of students in the field of laser-based technology is very desirable. The general questions of different laser-based technologies (characteristics of technological lasers and laser radiation, optical schemes, main laser-matter interaction problems etc) and questions of specific technologies (cutting, drilling, hardening, welding, film machining etc) are considered in the book of problems. The necessary theoretical information, the examples of solving of problems and the main thermal and optical properties of some material are given.
The expression allowing measuring the ratio by a Boltzmann constant k to an elementary charge e in experiment on a stationary heating of a wire by a direct current is received.

is described. Students should observe a temperature change of Fermi level location
and the corresponding change of the electronic conductivity; determine the
entropy and the enthalpy values for Ag
The principles of are given. It's displayed that the variety of the physical and mechanical properties are caused by the different types of crystal structure of SiO2. The principal elements of the theoretical calculation of X-ray radiation pictures for the different types of sand are shown.
The method of investigation of the heat diffusion in metal rod is developed. The experimental technique of solution of the linear heat diffusion equation at the given temporal and boundary conditions is suggested. The temperature distributions along the rod at the different time moments are obtained. Furthermore, we describe the methods of treatment of experimental data using the mathematical computer programs developed at last years.
A simple experiment to observe a skin effect in the ferromagnetic (iron) wire using a low frequency ("sonic") generator and an electronic voltmeter is proposed. The value of internal impedance of the wire has been chosen as the basic controlled parameter. The experimental results of investigating the normalized internal impedance as a function of ac current frequency are in complete agreement with that predicted by the skin effect theory for the case of cylindrical conductor. The magnitude of the magnetic permeability can be immediately revealed from the experimentally obtained data.
Is described simple in manufacturing Multi-Pendulum model of environments, for an illustration of the wave phenomena. The opportunity of demonstration of phase and group speeds, dispersion law, influence on dispersion of the various factors is shown.
The article is about methodological features and results of carrying out physics laboratory trainings based on usage of the computer models in an institute of higher education. The topics of lectures and practical works were equal to the topics of virtual physics trainings it allowed to use frontal method, when all students have the same task for practical work, but different parameters of the experiment. The computer models make it possible to carry out research works in molecular, atomic and nuclear physics. Virtual physics trainings can be recommended to use for distant teaching.
Set of computer laboratory works in general physics for training of foreign students develops in TPU. Application of computer laboratory works advantage forming of integrated perception of world, attaching of lecture and practice studies material, preparation for performance of laboratory practicum on experimental plants, and consolidating of specific physics vocabulary of Russian language.
In this paper we discuss the several educational computer experiments on molecular physics with employment of model of molecular interaction as elastic impacts of solid spheres.
Methods of studying the charged particles in crossed electric and magnetic fields dynamics combining the advantages of computer modeling and workable physical experiments with axial symmetry vacuum diode located inside the solenoid are described. The suggested methods may be used in laboratory practical work as well as for practical training or at lecture demonstrations.
