Biography
Born on September 5, 1930 in Leningrad, in the family of a chauffeur, later a plant director.
In 1932, the family moved to Moscow
In 1948 he graduated from school with a gold medal.
In 1948-1953 he studied at the Department of Theoretical Nuclear Physics, Physics Faculty, Moscow State University .
Since 1954 - works at the Institute of Physics of the Earth named after O. Yu. Schmidt of the Russian Academy of Sciences , first as a graduate student, then as a research assistant, since 1983 - Head of the Laboratory of Theoretical Geodynamics.
In 1963 - defended his candidate. He built the theory of metal phase transitions and theoretically showed that pressure of tens of millions of bar is needed to convert mantle oxides to metal, and therefore the core of the Earth cannot consist of metallic silicates, as was supposed at that time.
in 1971 - defended his doctoral thesis on the topic "Physics of Jupiter ". Established that Jupiter is a gas-liquid planet, not a solid ice, as previously supposed. The concept of a gas-liquid state of all giant planets (including models of their internal structure), developed jointly with V. N. Zharkov and co-workers, was confirmed during the passage of American spacecraft and has now become generally accepted.
In 1986 he was awarded the title of professor. In the works with his graduate students, a new theory of convective heat and mass transfer in the mantle and igneous chambers with the deposition of crystals was built. This theory generalizes the classical theory of Rayleigh-Taylor and is used to quantitatively describe the processes of heterogeneous differentiation of a substance in a gravity field.
Based on mathematical modeling, he developed the foundations of a new tectonic theory - the tectonics of floating continents. This theory combines the ideas of A. Wegener (1880-1930) about the floating continents and the theory of tectonics of the oceanic lithosphere, since it takes into account all thermal and mechanical interactions of the continents with the viscous mantle and the oceanic lithosphere, which “freezes” to the continents on passive margins and plunges into the mantle their active margins.
In 2000 - elected a corresponding member of the Russian Academy of Sciences .
