Dr. Olga Ladyzhenskaya

In the Misbehaving.net tradition of noting the lives and deaths of women in the sciences, I post this notice of the death of Olga Ladyzhenskaya, from whose work we benefit every night when we watch the weather reports:

Dr. Olga Ladyzhenskaya, a mathematician whose work with differential equations contributed to advances in the study of fluid dynamics in areas like weather forecasting, oceanography, aerodynamics and cardiovascular science, died on Jan. 12 in St. Petersburg, Russia. She was 81.
