It discusses her major mathematical discoveries including her work related to partial differential equations. Sofia Kovalevskaya was born in Moscow in 1850. Her family lived well. Sofia's father was a general in the Russian army. The family valued education and provided tutors for Sofia when she was a young girl. At this time Moscow was the capital of the Russian and not unlike other major cities in Europe, it was dealing with forces of change. At this time girls were not able to get a higher education. But Sofia persisted and eventually she was able to get a degree in mathematics and was awarded a doctorate. Sofia studied advanced mathematics, in particular, partial differential equations. She also studied physics and especially the role of mathematics in physics. Eventually Sofia started working at the University of Stockholm in Sweden. Sofia had many challenges to overcome.
