Pythagoras Eagle and the Music of the Spheres by Anne Carse Nolting

Three children – Shawna, Adin and Tavia – are math aficionados who are trying to crack the Beale Ciphers, a set of 3 documents from the early 1800s which supposedly encode information about a treasure.  Along the way, they run into many interesting mathematical topics like factorials, Fibonacci numbers, triangular numbers, substitution ciphers, and Pythagorean numbers.

This is a live-streamed event.  Occasional video recordings are made available for a fee at

Cover of book, "Pythagoras Eagle and the Music of the Spheres"
