Happy 𝝅 Day! We’re celebrating with Reuleaux polygons and the remarkable property that ties them to 𝝅. We’ll also take a look at some of the many applications of these interesting shapes, touch on some big mathematical results, and even share a few open questions in the world of Reuleaux polygons!

In the newsletter, we shared problem 64 from this year’s 100 Problem Challenge. Before we dive into solving the problem, we hope you’ll take some time to work on the answers and uncover a pattern…

Each summer, BEAM helps students in our 9-year Pathway Program find summer enrichment programs to help pursue their interests in science, technology, engineering, and mathematics. Students have participated in PROMYS, MathPath, and many different pre-college programs. This August, we spoke with three different BEAM students about how they spent their summers.

Building on what we learned last summer, we made key changes to our online tools and other program elements to build a strong community and encourage students to dive deep into problem solving this summer. After the program, Ayaan told us, “This summer made me realize that the math I enjoy is the creative, puzzling kind.” Here are some highlights…
