The nature of sound and vision in relation to colour

The increasing role of sound within the visual arts context and the trend in postmodernism towards interdisciplinary artworks has demanded a heightened awareness of the audio-visual. This paper explores some of the fundamental physical properties of both sound and colour, their similarities and differences and how the audio and visual senses are related. Ways in which soundscapes have been combined with paintings in exhibitions by the author will be used to illustrate how the two media can be combined to enhance the overall artistic experience.     

The nature of physics

The Doppler shift in frequency of an ionospherically reflected radio wave can be used to study various ionospheric disturbances. In this article the experimental arrangement for measuring such a shift is described, and examples of frequency shifts associated with solar flares, geomagnetic variations and travelling disturbances are discussed.     

The physics of diamond

The accurate measurement of the thermal conductivity of metals still poses considerable experimental difficulty. The reasons for this, and the main ways in which the problem has been approached, are summarized. A detailed examination of the development in technique and methods of measurement shows that while most of the steady-state methods introduced over 50 years ago are still being improved, the emphasis in the last few years has been on the development of methods which give more rapid results, particularly at high temperatures.     

The physics of photons

The intensity of the electromagnetic field is treated using the photon wave function in the usual probabilistic sense, as governed by Maxwell's equations. The dynamic characteristics and symmetry properties are determined. The uncertainty relations are found, from which the degree of localization follows for single particle states.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 9, pp. 46–50, September, 1989.

The physics of lightning

Despite being one of the most familiar and widely recognized natural phenomena, lightning remains relatively poorly understood. Even the most basic questions of how lightning is initiated inside thunderclouds and how it then propagates for many tens of kilometers have only begun to be addressed. In the past, progress was hampered by the unpredictable and transient nature of lightning and the difficulties in making direct measurements inside thunderstorms, but advances in instrumentation, remote sensing methods, and rocket-triggered lightning experiments are now providing new insights into the physics of lightning. Furthermore, the recent discoveries of intense bursts of X-rays and gamma-rays associated with thunderstorms and lightning illustrate that new and interesting physics is still being discovered in our atmosphere. The study of lightning and related phenomena involves the synthesis of many branches of physics, from atmospheric physics to plasma physics to quantum electrodynamics, and provides a plethora of challenging unsolved problems. In this review, we provide an introduction to the physics of lightning with the goal of providing interested researchers a useful resource for starting work in this fascinating field.     

The state of ferroelectric physics

Conclusions It can be concluded from this review that ferroelectric physics is one of the actively expanding branches of solid-state physics. The concepts of states related to the ferroelectric one, e.g., the ferroelastic state, have broadened significantly. Within this field successful studies are being performed of such general questions as phase transitions, subsystem interactions, i.e., the interaction of different quasiparticles, and other nonlinear processes. In ferroelectric semiconductors the interaction of charge carriers with spontaneous polarization is being studied, while in Seignette ferromagnetics the interaction of magnetic and electric subsystems is under investigation. Nonlinear phenomena are given special study in the phase transition region.A number of new interesting phenomena have been discovered in ferroelectric studies recently: phonon echo, photovoltaic effect, autolocalization of charge carriers in the phase transition region, etc. Many new classes of ferroelectrics have been discovered, thus demonstrating the broad extent of the ferroelectric state in nature. Apparently, certain organic compounds and liquid crystals may be classified as ferroelectrics. Results of ferroelectric studies are widely used in the national economy.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 1, pp. 5–39, January, 1979.
