Variational methods for solving nonlinear equations (differential, integral, etc.) are perhaps the most common methods at the present time. However, the history of their origin and development, both in the USSR and in the whole world, has not been studied enough. The author attempts to fill this gap, limiting himself mainly to 1920's-1950's, starting with Hilbert’s works on justification of Dirichlet...
Chance has always accompanied man. He was afraid of the elusive forces behind him, but he was also fascinated. Relatively late from this fascination arose the understanding that in some circumstances chance can be measured and, consequently, with the help of mathematics to reveal the regularities behind it. It began with gambling games already known in ancient times, such as the dice game popular...
