Definition
Andrei Markov was a Russian mathematician. He is best known for his work on stochastic processes, particularly what are now called Markov chains. These chains describe sequences of events where the probability of each event depends only on the state attained in the previous event. This concept has applications in various fields, including physics, statistics, and computer science. His work laid the foundation for many modern algorithms and models. Think of him as a pioneer in probability and statistics.
