## News from the world of Maths

Today is International Women's Day! *Plus* is run entirely by women who are happily disregarding maths and gender stereotypes, so we're very pleased to join in the celebrations. We've got lots of content by or about women mathematicians on *Plus* and here are some of our favourites.
