JAKARTA – Google Doodle today, Thursday (07/03/2019) commemorates the 97th birthday of Olga Ladyzhenskaya. He is a mathematician known for his work in exact differential equations (PDE) and fluid dynamics.
Born in Kologriv, the former Soviet Union region on March 7, 1992, Olga has produced more than 250 journals. His research on exact differential equations has contributed to the advancement of fluid dynamics studies in various fields such as oceanography, cardiovascular science, aerodynamics, and weather forecasting.
“He may be one of the most important mathematicians from Russia,” said Dr. Marshall Slemrod, a mathematician at the University of Wisconsin, to The New York Times when Ladyzhenskaya died at the age of 81.
“If you believe in weather forecasts, you have to solve the equation that he studies,” he continued.
Olga’s scientific career does not always run smoothly. He had to face many obstacles under Joseph Stalin’s government regime. Olga was banned by the Soviet government from entering Leningard University because his father was considered an enemy of the state.
Quoting The Independent, Olga’s father, Aleksandr Ivanovich Ladyzhenskii himself was a person who had a big influence on Olga’s life. He was the one who encouraged Olga’s interest in mathematics from a young age. Ladyzhenskii was believed to have died in 1937 in a detention cell after being captured by Soviet authorities named NKVD or secret police. At that time Olga was only 15 years old.
As a result of the ban, Olga finally chose to teach at an orphanage and secondary school before entering Moscow University in 1943. During his education at Moscow University, Olga got a golden opportunity to study under the supervision of the famous mathematician Ivan Petrovsky.
Graduating from there, Olga then continued her doctoral studies at the University of Leningrad. His journey at Leningrad University was not easy, the thesis he completed in 1951 could only be published in 1953 after Stalin died.
Although living under oppression, Olga is known not to be afraid to express her opinions on social issues. St. University Andrews even wrote these expressions often threatening his safety.
Not only has critical thinking, Olga is also friends with Aleksandr Solzhenitsyn, a writer who often criticizes the Soviet Union’s government. The poet Anna Akhmatova, whose work contains many criticisms of Stalin’s regime, is known to have good relations with Olga.
Olga began tasting freedom in 1989 when the communist government ended following the collapse of the Soviet Union. He then began teaching as a lecturer and became a researcher at the Steklov Mathematical Institute. After his career continued to climb, in 1991, he was appointed as head of the Mathematics Physics Laboratory.
Although the economic conditions in his country deteriorated since the end of the Soviet Union, Olga continued to choose to settle in Russia. He later became a member of the St Petersburg Mathematical Society in 1959 and in 1990 occupied the presidency of the organization.
Throughout his life, Olga has published hundreds of studies. He was awarded the Lomonosov Gold Medal in 2002 for his contribution to the progress of mathematics. Olga died two years later on January 12, 2004.
