Math Therapy How math can help prison inmates turn their lives around w/ Christopher Havens

Christopher Havens is a mathematician with published research in number theory, but what makes him unique among fellow scholars is his entire career in math has taken place in prison where he is serving a 25-year murder sentence. Math was the catalyst and ongoing foundation for his rehabilitation, and along the way he founded the Prison Mathematics Project which provides resources to inmates across the US.
In recognition of his years of rehabilitation, mathematical research, and community building, the Washington State Pardons & Clemency board unanimously recommended his sentence be reduced last year, but last month the request was denied by the state governor. So we thought we'd bring you Vanessa's 2021 interview with Christopher which remains just as thought-provoking and inspiring today.
