In this episode, we interview Dalhousie University mathematician Dr. Jason Brown. We talk to him about his early days playing guitar in a band with his siblings, the real-world applications of graph theory, and the mathematics behind Beatles music.

In his free time, Dr. Brown enjoys playing music and writing songs. He’s been performing in front of audiences for decades and has even recorded his own album (Songs in the Key of Pi).

Back in 2004, some of Dr. Brown’s research made international headlines when he first used the power of math to figure out what was really going on with the mysterious opening chord of A Hard Day’s Night by the Beatles. Since then, he’s continued to explore music mathematically and publish the results.
