It is shown that teaching of Physics in secondary and higher technical school is based on fundamentals and has important competing aspects: fundamental physics as a natural science and fundamental worldview as the basis of technical specialty. Therefore there is a need for optimal incorporation of these features in the organization and conduct of sessions. There are a number of traditional issues in Physics as worldview science that should be considered in lectures, practical seminars and student conferences. The great mystery of physics is the problem of dualism, when electromagnetic waves and light waves can be also the particles. But in explaining the nature of light wave approach obviously contradicts to the corpuscular approach. From the point of view of the wave theory light is a wave and in accordance with the principle of Huygens each point of the wave surface is a source of new waves. The light from the point can pass to the point of observation. And from the point of view of corpuscular theory light is seen as a beam of particles  photons. Because the photon has momentum, it cannot pass to the point of observation. Hence, wave and corpuscular approaches are in contradiction and cannot explain the problem for hundreds of years. This means a wrong approach. The wave is the wrong approach for wave propagation environment is required. Huygens believed this environment was hypothetical “ether”. We know that the “ether” does not exit. Consistent explanation is that there are in fact fundamentally different waves  waves without environment. This is the wave of particles that fly with internal oscillation motion. Similarly, as is the spread of light photons moving in space that are in the process of oscillatory type: energy→mass→energy→mass→... The possibility of such oscillatory process follows from the known relationship between mass and energy: Similar oscillations occur in other wavelengths. In particular, radio waves  waves and particles too, but in books on radio engineering or physics this is not said. It is suggested opinions that the fundamental problem questions of physics should be the subject of discussion with the students, so they should be considered in lectures, practical seminars and student conferences. It helps to enhance the learning process and develop a creative atmosphere, which is important for the formation of future specialists.

The grain size diameter is the main parameter characterizing a given metallic alloy. In the case of Al-Si or Fe-C eutectic alloy the average inter-lamellar spacing is a good parameter which seems to be adequate to describe this irregular structure. To define the average inter-lamellar spacing the regular areas within generally irregular structure has been distinguished. It has been postulated that the formation of regular structure could be related to the minimum entropy production criterion. From the other side the maximum destabilization of the non-faceted phase interface could be referred to marginal stability. The criterion of minimum entropy production allows to formulate the growth law for regular lamellar structure solidifying under stationary state. It defines the regular eutectic spacing versus growth rate. The marginal stability concept allows to define the maximum wavelength which can be developed at the solid / liquid interface of non-faceted (Al) phase. It defines the maximum spacing within irregular structure taking into account the wavelength of instability (marginal stability) created at the non-faceted phase interface. An average inter-lamellar spacing results from the relationship formulated on the basis of both spacings. It should be emphasized that both conditions (criteria) are deduced from the thermodynamics of irreversible processes. The simplified scheme of irregular structure incorporates, additionally the intermediate lamella of faceted phase that is also taken into account in the definition of average inter-lamellar spacing, [...] . The intermediate morphology existing between two distinguished distances is treated as being under oscillation between stationary state and marginal stability. The state of marginal stability is defined by a vanishing excess entropy production. Therefore, it is suggested that the structural oscillation takes place between an attractor and point of bifurcation in the system.

The article broaches the relationship of the Byzantine liturgical hymn called the Akathist with Litany of Loreto. Both prayers are addressed to the Virgin Mary, the two also combine three topics: dogmatic, liistoriosopliic, and eschatological. Theological thought links them closely together in a poetic form of communication. Therefore, they are fundamental to the development of Marian spirituality.
