Abstract
The nonexistence of a solution to a generic algebraic equation of degree 5 (or higher than 5) as a finite combination of its coefficients using radicals and finite field operations is one of the first and the most important impossibility results in mathematics known as the Abel-Ruffini Theorem. The usual proof is not accessible without the machinery of the Galois theory. Lecturing to Moscow High School students in 1963-1964, Arnold provided an elementary proof of this fundamental result. I will attempt to explain his proof.
