Pafnuty Chebyshev

Pafnuty Chebyshev was a Russian mathematician known for his work in probability, statistics, and approximation theory. He developed methods to estimate how closely polynomials can approximate functions, which has applications in engineering and data analysis. Chebyshev also formulated the Chebyshev inequality, providing bounds on how much a random variable can deviate from its average, foundational in statistics. His contributions help us understand and predict patterns in data, making him a key figure in the development of modern mathematical methods used across science and technology.
