The biomechanical transactions of professor G. V. Kolosov

The G. V. Kolosov's works on the biomechanics are discussed. Gury Vasilievich Kolosov (12(in the old style) 08.1867 – 1936) was born in the village of Ustie (Novgorod province). In 1889, he graduated from St. Petersburg University with a first degree. His research issue was “Torsion prisms”. Since 1902 he was Assistant Professor in Yuriev (Tartu) University. In May 1903, he defended his master's thesis “On some modifications of Hamilton principle applied to issues of solid mechanics”. In 1910 he defended his doctoral thesis “An application of the theory of functions of a complex variable to the plane elasticity problems”. According to the academician of the Georgian Academy of Sciences N. I. Muskhelishvili, student G. V. Kolosov, “was the first who managed to express the general solution of the plane problem by way of 2 (independent from each other) analytic functions of a complex variable, which makes it possible to apply well-developed theory of analytic functions to the plane problem”. Formula Kolosov–Muskhelishvili is known in the theory of elasticity. From 1913 until his death Gury Vasilievich headed departments of theoretical mechanics in Petersburg Electrotechnical Institute and in the University. He was convinced that “the student must quick be putted into position in science where they shoot”. In 1931 he was elected a corresponding member of the USSR Academy of Sciences. Besides Gury Vasilievich — the author of works on biomechanics. His idea was that the mathematical method of research may apply to everyone phenomena around us. In Tartu University G. V. Kolosov explained to medic N. Kornilovich the structure of bone from the perspective of the theory of elasticity. In his monograph, published in 1935, G. V. Kolosov stressed the importance of the law of the Wolff. In this monograph the author has pictures isostatics (lines of equal stress) in the bone. G. V. Kolosov had written work on the application of mathematical probability theory to the problem of infection eclampsia (Vrach. 1901. No. 32) and the mathematical theory of the device for determining blood pressure.
