Girls’ Angle Bulletin, Volume 14, Number 1

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

We open Volume 14 with the first half of a two-part interview with Williams College Associate Professor of Mathematics Pamela E. Harris. Prof. Harris’s journey into mathematics is extraordinary and quite unique. She also coauthored a wonderful contribution to the Bulletin in Volume 11, Number 2, entitled “Partitions from Mars”. Prof. Harris is actively involved in promoting minorities in mathematics. Among her many talents, Prof. Harris is expert at involving undergraduates in mathematical research.

Next, Deanna Needell gives us a survey of the various ways in which she and her team has studied Lyme Disease using machine learning. With the vast amounts of data being produced every second today, there is no hope for humans to analyze it all without the aide of computers. But computers are only as good as the algorithms that run on them. Data Science is a burgeoning field full of opportunities and promise.

Have you ever noticed how difficult it can be to keep track of multiple characteristics, even if the characteristics only come in two flavors, especially if the various characteristics influence each other? In Switcheroo!, Lightning Factorial tests your ability to stay organized in the face of many influencing, two-valued, switches. All you have to do is determine whether a light bulb is on or off. Good luck!

We enjoy turning activities that lend themselves to collaboration into mathematical activities. For example, crossword puzzles and jigsaw puzzles work really well as group activities, and at Girls’ Angle, we’ve “mathefied” both. (The first instance of a “mathefied” jigsaw puzzle is due to Girls’ Angle mentor Elise McCormack-Kuhman.) Word searches also lend themselves to collaboration, so we “mathefied” that this fall to create an activity that works well in the virtual world. Addie Summer provides a few example for you to try your hand at, as well as posing a number of math questions pertaining to these “number searches”.

Emily and Jasmine spent an afternoon building an icosahedron out of toothpicks. If you’re interested, they provide detailed instructions. They also analyzed the shape of the column of water that falls from a tap in a new installment of Emily and Jasmine’s adventures in The Water Column.

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!
