Prison Math Project


In early 2012, a prisoner by the name Christopher Havens began studying mathematics for the very first time within the prison inside of prison. We know this form of isolation by the name solitary confinement… prisoners know it as “the hole”. Having no other form of stimulation, mathematics occupied every hour of Christopher‘s days, lasting the better part of a year until he was released back into the general population. In so many cases, the negative effects of prolonged isolation manifests itself through the behaviors in both the short and the long term. However, this case is one where a mix of isolation and the transformative powers of mathematics caused Christopher to undergo a steady chain of personal growth while igniting within him a passion for mathematics.

As his studies continued and they began to have deep meaning, he started branching out from the standard curriculum and took an interest in algebraic systems and number theory. In January 2013, these beautiful areas of mathematics inspired him to write a letter to the Annals of Mathematics. Several months later, a single letter was sent from across the ocean to Christopher Havens from Professor Luisella Caire of the Politecnico di Torino, in Italy.
As his long awaited questions began being answered, Luisella supplemented Christopher‘s self-studies by giving him feedback and introducing him to intriguing problems. She provided him with material that would inspire him to explore different areas of mathematics. As Luisella watched Christopher grow, she sent him books and journals, as well as “Math News” letters. Some were personal textbooks used by both her and her husband, Umberto Cerruti, which were sent with personal inscriptions. Unfortunately many of the texts were rejected by Christopher‘s prison for various reasons.

The guidelines for prisoners receiving books are becoming more and more restrictive, and so after a more than a year of so many priceless rejected books, Christopher had the idea of a math program for which he sent across the ocean. Luisella and Christopher sent their ideas back and forth with the rough idea being to establish a math program with a classroom and a library containing every last one of the previously rejected books. In 2015, Christopher was transferred to a minimum security unit as a result of his exceptional behaviors, and he began working to start the program.

In early 2016, after pleading, proposals, and pitches, Christopher sat in a room with one of the Prison’s staff members and watched as the moment of approval came. As the staff member sent emails to the scheduling personnel, the program was missing one thing before it could be finalized.. a name. The staff member turned his head from the screen and said “What are you going to call it?” Christopher responded with “Do I have to give you the name right now?” “Yep… right now.” Having somehow missed this important detail in the planning, Christopher responds with “The Prison Mathematics Project!”. And with a grunt of approval, the PMP was born.

The Prison Mathematics Project holds meetings twice weekly where they discuss mathematics, collaborate on large projects and work together on their very own “PMP Solving Team”. In the Solving Team, prisoners search math magazines (such as MAA Horizons) and solve the problems in the back sections. Unconventional teaching took place to accommodate a group of math enthusiasts whose mathematical maturity varied greatly from one to the other, thus resulting in a truly unique experience for each participant.

In 2016, PMP had its first annual Pi Day celebration inside of a small classroom and by 2017 mathematicians flew from across the globe to see our newly established annual events. PMP events have become an avenue for mathematicians to share their passions for mathematics in the form of lectures in front of an assembly room with upwards of 100 prisoners, all with one commonality – they were hungry to learn. In turn, prisoners give speeches and have contests with both staff and mathematicians. In addition to the limericks being shouted, the interactive experiences, and a level of mathematical hunger never before experienced in prisons, the PMP became a small piece of the mathematical community behind prison walls.
