On May 26, we celebrated the 80th birthday of Viktor Pavlovich Silin, a corresponding member of the Russian Academy of Sciences and a world-famous theoretical physicist, who contributed greatly to plasma physics and solid-state physics. His entire professional life has been linked with the Lebedev Physical Institute, where he began to work after graduating in 1949 from Moscow State University and where he progressed from a junior researcher to head of the Division of Solid-State Physics (1989– 1995). Over this period, he published about 700 papers in different fields of physics and four monographs. During the first 10 years of his work in the Theoretical Department at the Lebedev Institute, Silin obtained a number of important results on the theory of Fermi liquid in metals. Later, he concentrated on two fields of research: the theory of condensed media and the physics of gaseous plasmas. Many of Silin’s results on the physics of metals and semiconductors became an integral part of solid-state physics, were confirmed experimentally, and were further developed in the studies of his numerous followers. At present, Silin and his pupils are actively working on the theory of Josephson junctions in superconductors. Among his studies in the field of gaseous plasma physics, the most notable are those on the kinetic theory and stability of plasmas. Silin’s paper on the parametric resonance in plasma, which was published in 1965, is of fundamental importance for understanding the properties of plasma in a strong electromagnetic field. This paper received much attention and paved the way for many subsequent investigations on nonlinear processes in plasmas. Silin and his pupils laid the basis of the theory of parametric instabilities and parametric turbulence, which was then applied to investigate the interaction of high-power laser radiation with plasma. At present, Silin is continuing his studies on the generation of laser radiation harmonics, which he started in the 1960s and which have become especially challenging in recent years. Silin was twice awarded the USSR State Prize: in 1970 for the series of studies on the Fermi liquid theory and in 1987 for studies on nonlinear plasma theory. For his scientific activity, Silin was awarded two Orders of the Red Banner of Labor. He was conferred the title of an Honored Scientist of the Russian Federation. Silin is a member of the editorial boards of several scientific

journals. He is a member of a number of scientific councils and a member of the Scientific Council on Plasma Physics of the Russian Academy of Sciences. Over many years, he actively participated in organizing all-Union conferences on the interaction of electromagnetic waves with plasma and was a member of organizing committees of a number of international conferences on plasma physics. Along with his active involvement in scientific research, Silin devotes much time to teaching young scientists. For many years,
