Yakov Grigorevich Sinai is one of the most influential mathematicians 
                    of the twentieth century. He obtained numerous groundbreaking 
                    results in the theory of dynamical systems, in mathematical 
                    physics and in probability theory. Especially his ingenious 
                    insights and pioneering works practically shaped the modern 
                    metric theory of dynamical systems (also often called after 
                    Kolmogorov the theory of stochasticity of dynamical systems). 
                    Sinai was the major architect of the bridges connecting the 
                    world of deterministic (dynamical) systems with the world 
                    of probabilistic (stochastic) systems.
