50 Years in Physics

I am a Doctor of Sciences in Physics. I belong to the school of physicists established by Alexander Prokhorov–Nobel Prize Laureate in Physics. I am a Laser Physicist by education, having published over 150 papers. I graduated from Moscow Institute of Physics and Technology with High Honors in 1970. I am eternally grateful to Academician A. M. Prokhorov and Prof. A. A. Manenkov, whose influence on my scientific life has been decisive. 19 years ago, I developed an interest in Cosmology. I have been elaborating a model I dubbed World-Universe Model (WUM) and published a series of papers in the Journal of High Energy Physics, Gravitation and Cosmology WUM is a natural continuation of Classical Physics, and it can already serve as a basis for a New Cosmology proposed by Paul Dirac in 1937. In my view, there is a principal difference between Physics and Mathematics. I am convinced that Physics cannot exist without Mathematics, but Mathematics must not replace Physics. I absolutely agree with John von Neumann who said: “The sciences do not try to explain, they hardly even try to interpret, they mainly make models. By a model is meant a mathematical construct, which, with addition of certain verbal interpretations describes observed phenomena. The justification of such a mathematical construct is solely and precisely that it is expected to work”.
