And groundbreaking Iranian mathematician Maryam Mirzakhani has died. A professor at Stanford University, she is the only woman and only Iranian to have ever won mathematics’ highest award, the Fields Medal. She died Saturday at the age of 40 from breast cancer. Multiple Iranian newspapers broke social taboos by publishing photos of Mirzakhani without a hijab, after Iranian President Hassan Rouhani posted a picture of her on Instagram without her head covered.
