Introduction

Abstract

Leonid Isaakovich Mandelstam is an outstanding physicist, not only in his home country, but in the context of world science. In the book “Russian physics of the Nobel Level”, L.I. Mandelstam is mentioned among nine scientists who could have received the Nobel Prize, but have not. Some of them have not received the Nobel Prize because it cannot be given posthumously. Others (including L.I. Mandelstam and G.S. Landsberg, who decisively contributed to the discovery of combinational scattering of light) have not received the Nobel Prize under the force of circumstance. The Indian physicist Sir Chandrasekhara Venkata Raman received the Nobel Prize for the discovery of the combinational scattering of light. This effect is named in honor of him.
