The cover shows the Hasse diagram for the partially ordered set of partitions show Young diagrams fit inside a 4 row by 3 column rectangle. For more on these beautiful structures, see Robert Donley’s latest installment in his multipart series on partitions on Page 8.
For our interview, we continue with the second installment of our 4-part interview with the Theresa Mall Mullarkey Associate Professor of Mathematics at Wellesley College, Karen Lange. There’s lots of great advice in this installment!
We continue exploring the ramifications of an approach a group of 8th graders at the Buckingham, Browne, and Nichols Middle School came up to find Pythagorean triples in Follow Your Nose, Part 2.
Emily and Jasmine continue their investigation of rational rompers, this time focusing on finite rational rompers that represent the same rational numbers.
We have a Learn by Doing on random numbers. Remember: If you ask someone to pick a random number, you have to specify a mechanism or a probability distribution!
In Alphanumerics, we imagine what an alien mathematician might think upon encountering the alphabet for the first time.
Some members at the club worked on ways to fold regular polygons with the techniques of origami. In this issue, we provide folding instructions for a regular pentagon. Can you prove that it works?
We conclude with Notes from the Club.
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!
Also, the Girls’ Angle Bulletin is a venue for students who wish to showcase their mathematical achievements that go above and beyond the curriculum. If you’re a student and have discovered something nifty in math, considering submitting it to the Bulletin.
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!
