        Pak V.V. was born 20 may 1935, in family of prominent learned-miner, academician Academy of Sciences of Ukraine, founder of Donetsk scientific school of mountain mechanics Vitold Stepanovich Pak. On finishing of Donetsk industrial institute, where Vitold-younger successfully combined an excellent studies with public work and concert activity, being one of organizers first in country student symphojazz, was directed to work in Fedorov Institute of mining and actively included in creation business of new more effective ventilation funds of deep, highly productive mine and mine. After five lethes by him is done a big volume of experimental researches on creation aerodynamic of schemes of centrifugal ventilators of high economy and worked up method aerodynamic of them computation, putting together maintenance of his candidate dissertation, stuck in 1963, and up for chronicled Academy of Sciences USSR "Mechanics in USSR during 50 years" (volume 2, page, 832, 854).

       By Material for his doctoral dissertation, defended in 1971, began the computation methods and rational profiling of all of installations elements of main and local ventilation, founded on principle безотрывного flowed by stream of hard borders, pulled out by candidate for a degree on air moving description in not compact conduit of big extent, on optimum field coverage of vent routines by working domains by the medium of methods of mathematical pilings theory and coverages and oth., that allowed to provide bringing of losses in installations on 20-30 %, essential sizes abbreviation down, laboriousness attached to their building.

        Wide erudition, high level of theoretical preparation, fine ownership by experiment, ingenuity, complex approach to decision of tasks with calculation of all of creation components and functioning of mountain engines - here constituents of creative laboratory's Pak. Therefore while arose a question about improvement of mathematical education of mountain engineers in Donetsk polytechnical institute, him invited in 1976 to lead a chair of higher mathematics. This selection found oneself very successful, so far as after small time he began by chairman of Scientifically-methodical commission on Ministry mathematics of Ukraine education, arranged for row of educational manuals on mathematics for engineering specialities.

       Except of prominent works in domain of mountain engines professor Pak belong the large results in domain hydrodynamics, pilings theory and coverages, mathematical modeling of natural and technological processes (sequence method of simple models), pedagogics and philosophies.

       Under guidance professor Pak stuck up for 8 doctoral candidate and 3 dissertations, to them published about 370 scientific labour, in that number one textbook, eight monographs, 118 author evidences and foreign patents on inventions, methods sacred to perfection and mine ventilation funds, to creation of more progressive schemes shaft pumping, to fight with noise and vibration of mountain engines (in education source ), to elaboration of new forcing method of ventilators being in exploitation of main ventilation, permissive without capital expenditures sharply to improve upon ventilation of underground making. His inculcation on 20 mine of Donetsk region gave a big social and economic effect, after that in 1987 World organization of intellectual property attached to United Nations Organization rewarded professor Pak by honourable diploma.

       After big endowment in science development and technique in 1992 professor Pak is embezzled a honourable rank of Deserved science figure and Ukraine techniques, and in 1994 him elect by academician of Engineering Ukraine academy.

       Its 60-year professor Pak marked by publication textbook first in Ukraine on mathematics for engineering specialities on ukrainian, which attached to fourfold lesser volume on comparison with analogous textbooks has a big information saturation and engineering orientation, and also monograph "Engineer, mathematics and others. Simple methods of mathematical modeling of natural and technological processes", where on numerous examples he brings secrets to light of engineering creation attached to decision of scientific and inventive tasks, and also mathematics role, philosophy, physics and other fundamental sciences in this creation.
