Google's Doodle celebrates Russian mathematician's 97th birth anniversary

NEW DELHI: Google's Doodle on Thursday marked the 97th birth anniversary of Russian mathematician Olga Ladyzhenskaya.

In the doodle, her portrait is seen at the centre and the Navier-Stokes momentum equation can be seen written at the bottom.

Born on March 7, 1922, Ladyzhenskaya was known for her work on partial differential equations and in the field of fluid dynamics.

She provided the first rigorous proofs of the convergence of a finite difference method for the Navier-Stokes equations.

Ladyzhenskaya's work on differential equation led to several developments in the study of fluid dynamics and paved the way for advances in weather forecasting, oceanography, aerodynamics, and cardiovascular science.

A daughter of a mathematics teacher, she graduated from Moscow State University and received a doctorate from Leningrad State University. She also earned a doctorate from Moscow State in 1953.

She overcame numerous hurdles in her personal life, including incarceration and the subsequent murder of her father. Her father, a descendant from Russian nobility, was executed by the Soviet authorities for being an "enemy of the state".

Her mother and sisters had to sell dresses to make ends meet.

Her admission to Leningrad State University, despite obtaining excellent grades in high school, was barred because of her family's background.

She died on January 12, 2004, in St Petersburg, Russia, at the age of 81.
