Results of the preliminary investigations on ways of thinking processes in solving physical problems are presented. The investigations were organized in high school classes for groups of students regarded by teachers as ...

Methods of turbidity measurement are discussed and a prototype of a turbidimeter, its design and parameters are described.

Temperature depedence of dielectric constant ε, electric conductivity, Seebeck's coefficient, were studied around the morphotropic boundary of the solution. On the ground of polaron theory of transport, charge carrier ...

To evaluate the possibilities of using sodium niobate in thermo-electric converters transforming heat energy into electric energy, the temperature changes of electric conductivity, of Seebeck coefficient and of the thermal ...

Temperature changes of the electrical conductivity and of the Seebeck coefficient for the ceramics $NaNbO_3$, and $NaNbO_3$ + 0.2% mol $La_2O_3$, have been investigated. The obtained results have been used to define the ...

The impact of heavy ions on various gaseous targets was observed within the energy range available in the Institute of Nuclear Physics, Cracow 200 keV accelerator. The ions passing through a gas target were recharged and ...

The results of checking knowledge of physics in a secondary school have been worked up with the use of the two methods mentioned above. The result received in both mothods proved comparable, though the method based on ...

The evidence of slaw discharge currents in PbZrO[3] near the phase change is given. Current measurements were carried out in the temperature range 180°C-280°C. The results prove the existence of three exponentially ...

The Spin Free Particle with the diffluence in the Center Mass System is described. The momentum of this particle is non parallel to velocity. The Klein-Gordon equation for this case is modified.
