Can Mass Turn into Energy?
The article presents a physics-philosophical analysis of the phrase "Can mass turn into energy?" It is shown that the phrase itself is meaningless from the physical as well as philosophical points of view. In particular it is shown that the common association of the expression with the special theory of relativity is in fact based on misunderstanding. Why Einstein Rejected Ether Hypothesis?
(On the Experimental Foundation of the Special Theory of Relativity) The article shows that the careful analysis of three crucial experiments leads to contradictions in the required properties of ether. Einstein resolved this situation by rejecting the concept of ether as a bearer for the electromagnetic fields. The electromagnetic fields were introduced therefore as irreducible realities. Numerous important consequences both theoretical as well as philosophical followed from the revolutionary rejection, notably the creation of the special theory of relativity. Rainbow Holograms In modern wave optics the physical principles of holography are considered, as a rule, on the basis of the set up of recording of the holograms in convergent (Leith and Upatnieks set-up) and in counter propagating (Denisyuk set-up) object and referent beams of light. In the present paper the methodical subject of record and reconstruction of the images with use of a method and set-up of rainbow holography, having now widest practical distribution, due to an opportunity of restoration of the images in white light of usual sources and technologically simple way of duplicating of such holograms are discussed.
Achievements of Physical Science in the Lecture Process: Conducting
into
Spin Electronics Attempt of Creation Transfer Network Creators and Consumers Educational
Equipment and Production for Association Physics Sub-faculties at a
Technical Universities of Russian Federation In this article the conception and the created program realization co-operation distant science centers physics sub-faculties in Technical Universities of Russian Federation based on actual Web-technologies are described. The created Internet-resource for Association physics sub-faculties in Technical Universities of RF, has the purpose to organize transfer of studying materials and create Distance Studying Physic System. Organization of the Internal Differentiation of Physics Teaching
in Technical
VUZ (Institute of Higher Education) on the Basis of Information Approach In the article is examined the problem of the organization of the internal differentiation of physics teaching in technical VUZ (Institute of Higher Education) taking into account the psychological special features of students, namely the individual styles of coding information.
The Derivation of Saha Equation within the Framework of General Physics The article considers the derivation of Saha equation for the case of two level model. It could be used for studying equilibrium ionization processes within the framework of a course on Basics of Plasma Physics for third- year students. The derivation of the equilibrium ionization constant is not based on a Gibbs canonical distribution but on calculation of different quantum states probabilities taking into account their degeneracy. The Methodical Questing of Employment of Computer Experiments in
Physical Education In this paper we discuss the question about methods of teaching of physical sciences because of progress of computer experiment and methods of training in computer laboratory practice.
The Complex of Computer Modeling Physics Laboratory Works: Principles
of Elaboration and Experience of Application in Educational Process Projecting and practical application of computer laboratory works are the important subjects in modern methodology and theory of physical education. In this paper the significance of information technology in educational process is analyzed. On the base of general pedagogical prerequisites the common principles of computer modeling laboratory work for using in course of physics elaboration are discussed. Studying of Bases of the Spectral Analysis on the Basis of the "Virtual
Monochromator" In the article the concept of realization of virtual experiment on studying of bases of the spectral analysis and of the optical monochromator for a university physics lab is presented. The technology of modeling of the experimental spectra, based on the real spectral database received on the precision scientific spectral equipment, and also a technique of performance of a corresponding students' laboratory experiment, are described. About Determination of Air Viscosity by the Time of its Free Flow through
the Capillary The laboratory work on determination of viscosity coefficient
is described. In this work the equipment
designed for determination of the adiabatic index by the Cleiman-Desorme
method is used. Study of the Dispersion Properties of the Flexural Waves
in the Spring The simple procedure of the study of the special features of the propagation of flexural waves in the thin plates and the rods based on the example of metallic spring from the tape of rectangular cross section is proposed. This method makes it possible to demonstrate three wave modes of those extending in the spring: "rapid" and "slow" wave of mutually perpendicular polarizations and longitudinal-bending wave with the cutoff frequency. The developed method can be used in the lecture demonstrations and in the training experiment on the principles of the vibration theory and wave theory. |
