Andrey Kolmogorov was a prominent Russian mathematician born on April 25, 1903, and he passed away on October 20, 1987. He is best known for his foundational work in the field of probability theory, where he established the modern axiomatic framework that underpins the discipline. His contributions have had a lasting impact on various areas of mathematics and science. In addition to probability theory, Kolmogorov made significant advancements in mathematical logic, topology, and turbulence. He was also involved in the development of algorithmic information theory, which explores the complexity of data and information. His work continues to influence researchers and practitioners across multiple fields today.
