Niels Henrik Abel

Niels Henrik Abel was a pioneering Norwegian mathematician known for his contributions to various fields, notably algebra, calculus, and number theory. He is best known for proving that there is no general solution in radicals to polynomial equations of degree five or higher, impacting algebra profoundly. Abel also made significant advances in the theory of infinite series and is recognized for the Abel-Ruffini theorem, which underlines the limitations of algebraic solutions. His work laid foundational stones for modern mathematical analysis, influencing future generations and establishing him as a key figure in the evolution of mathematics in the 19th century.
