It's quite a coincidence that your story is about this theorem because FW just published a piece about two teen girls solving a math problem related to that theorem this morning!!! You definitely must read this story and share it with your pupils. https://medium.com/fourth-wave/two-teen-girls-solve-a-2-000-year-old-math-conundrum-b610af4d0749

Thanks for your charming story. Lifelong learners (like you) are the smartest and most pleasant people I know. :)
