Thanks to a generous grant from Science House, Girls' Angle has begun producing the Girls' Angle Women in Mathematics Video Series. This series features women in mathematics presenting pieces of math that excited them when they were in middle and high school. New videos will be posted on the 30th of every other month starting with September, in alternation with the Girls' Angle Bulletin.

These videos, sometimes filmed on the spur of the moment and in a single take, aim to showcase the diverse group of women working in mathematics today. For a more formal presentation of material, join Girls' Angle! If a concept or comment in a video seems unclear, feel free to notify us at girlsangle "at" gmail.com. We love receiving comments from visitors to this website!

The Women in Mathematics video series was conceived by Girls' Angle director Elisenda Grigsby. If you are a woman in mathematics and would like to contribute to this series, please email girlsangle "at" gmail.com with the subject "Attn: WIM videos".
