Google Doodle today celebrates the 97th birth anniversary of Russian mathematician Olga Ladyzhenskaya. Ladyzhenskaya was known for her work on partial differential equations and fluid dynamics.
Author of more than 250 papers, Ladyzhenskaya was a member of the St. Petersburg Mathematical Society since 1959 and went on to become its president in 1990. The mathematician provided the first rigorous proofs of the convergence of a finite difference method for the Navier-Stokes equations.
Olga Aleksandrovna Ladyzhenskaya was born in the town of Kologriv in the erstwhile Soviet Union. Her father was a mathematics teacher and is credited with inspiring her love of mathematics.
Her father was labeled “enemy of the people” by the Soviet Union government, and when she was just 15 years old, he was arrested by the interior ministry of Soviet Union and soon killed.
Her family name denied her admission into the Leningrad University, one of the largest Russian universities, irrespective of her exceptional grades. But after the death of then Premier of the Soviet Union, Joseph Stalin in 1952, she was provided with a second chance.
In 1953, Olga Ladyzhenskaya presented her doctoral thesis and was a student of the famous Soviet mathematician Ivan Petrovsky. She was awarded the Lomonosov Gold Medal by the Russian Academy of Sciences in 2002 for her impressive contributions to the world of mathematics.
Google celebrated her birthday with a doodle and a YouTube video on her life and achievements. The Google doodle is in an elliptical shape, possibly paying homage to her work involving linear and quasilinear elliptic equations.
