The electronic version of the latest issue of the Girls’ Angle Bulletin is now available on our website.

From Day One, Girls’ Angle has wished to hire a woman with a doctoral degree in mathematics as Head Mentor at our club, where girls explore mathematics under the guidance of our stellar mentors. This wish is now a reality with the hiring of Grace Work as our new Head Mentor, and this issue’s interview is with her.

The dream is to create a professorial class whose teaching duties pertain to the K12 arena instead of college/grad. A main reason for this dream is the observation that many girls come to like math when they do mathematical research. At Girls’ Angle, many girls have come up with their own interesting math questions and have embarked on multi-month journeys as they sought answers, and that’s what math research is. Another reason is to have a Head Mentor who has a research mathematician’s understanding of mathematics and experience tackling unsolved problems.

Next, Deanna Needell gives her take on the stable marriage problem. This is Needell’s 10th installment of her column *Needell in the Haystack*.

Emily and Jasmine continue discovering beautiful facts about the pattern created by two zigzags running across a rectangle. They keep finding neat things and it sure feels like they’re going to stumble on a nice mathematical gem soon – stay tuned!

We close with the solutions to last issue’s Summer Fun problem sets, which include quite a bit on ordinals, including a result of Paul Erdős concerning the maximum number of different ordinals one can obtain by adding up ordinals in different orders.

We hope you enjoy it!

Finally, a reminder: when you subscribe to the Girls’ Angle Bulletin, you’re not just getting a subscription to a magazine. You are also gaining access to the Girls’ Angle mentors. We urge all subscribers and members to write us with your math questions or anything else in the Bulletin or having to do with mathematics in general. We will respond. We want you to get active and *do* mathematics. Parts of the Bulletin are written to induce you to wonder and respond with more questions. Don’t let those questions fade away and become forgotten. Send them to us!

We continue to encourage people to subscribe to our print version, so we have removed some content from the electronic version. Subscriptions are a great way to support Girls’ Angle while getting something concrete back in return. We hope you subscribe!
