"I can't volunteer to help him in his GED prep class... That is a security risk."

Nathan Kimbrell writes about the hurdles of prison education, and the loophole that allows him to trade the chaos of the cell block for the chaplain's office.

Nonlinear Transformations: An Algebraic Security Risk
Incarcerated mathematician Nathan Kimbrell reflects on the hurdles of tutoring in prison, where sharing equations becomes a rare escape from barbed wire and bureaucracy.

Last week, we learned that Governor Bob Ferguson denied Christopher Havens's request for clemency. While this is not the outcome we hoped for, it does not erase the incredible change Christopher has achieved. (1/3)
Statement by Christopher Robin Havens January 13, 2026 This last year was spent in anticipation of my release after receiving a 5/0 unanimous vote for a commutation of my sentence by the Washington State Clemency and Pardons Board. I think we all felt that the hardest part was over, and that the formality of the governor's signature was not even in question. Unfortunately, this was not the case. On January 6, Governor Bob Ferguson decided against my early release. I would like to thank the Washington State Clemency and Pardons Board for believing in me. Regardless of my release, I would like to thank Governor Bob Ferguson for his consideration. I would also like to thank all of you for your support, your faith in humanity, and for believing that there is a capacity for redemption in everyone. Over the past years, I have had incredible experiences working towards advancing my field in mathematics and in my humanitarian efforts with the Prison Mathematics Project. Among these experiences, there have been extraordinary achievements and moments that have changed people's lives. While the governor's decision was not favorable, this will not hinder my efforts to give back to the world, despite my reach being limited by my continued incarceration. I had some goals and dreams to be fulfilled after my release, including projects that were big enough to warrant waiting until I regained my freedom. Legacy projects. I will continue my work for PMP in a greater capacity, and I have also decided—in the spirit of perseverance—to unveil my plan to launch the international Math Haven Conferences, entirely devoted to widely accessible introductory areas, as well as to establish a new academic mathematics journal that will tie into the conference. This journal will be open access and will focus on intuition and accessibility. I want to put into context just how much is possible for a single individual, blindfolded and with his hands tied behind his back. I want to give the world more than what is possible in my limited capacity... and I will. Someday. Until then, I will continue in my own way of serving towards an infinite debt, and I will be ever grateful for your continued support. Ladies and gentlemen, go boldly towards your future, no matter the obstacles you face… and while we take each step, let's do our best to project into the world the beauty we want to see.

Imagine discovering your life's passion but having absolutely no one to share it with. For years, Travis studied in isolation, fearing that the academic world wouldn’t accept him. But one day, he took a risk.

Mathematicians + intriguing problems + a supportive community = transformation.

This year, PMP organized seven Math Circles in correctional facilities in Canada, Florida, Illinois, North Dakota, and Washington.

2025 was a year filled with new projects and growth for PMP. We are honored to continue this beautiful work in 2026! But first, let’s do a countdown to Christmas and recap what made our year special with our very own PMP Wrapped.

Mathematics can free minds in the tightest of constraints.

"Every time I opened a textbook or read a research paper, every day I stayed clean, every time I showed compassion to the people around me, I was fighting a system that wanted me to fail."

"Prison sucks that out of you, if you let it. You'll give up on yourself and the world too."

Math can be a liberatory force, transform lives and enrichen the human spirit in the face of adversity.

How do you learn to code from a prison cell with no computer?

For one student, it started with sending JavaScript snippets via email. That simple hack led to PMP's CodePraxis.

Now, the mission is to bring this project to prisons across the country.

Do you know an incarcerated person with a keen interest in math? You can help them feel a part of the math community while they're inside prison.

Contact us with their mailing info and we'll send them a physical copy of our quarterly newsletter.

Big news: we are expanding our digital space with a new blog!

Expect to see insights on math education, stories from our participants, and reflections on justice and the carceral system.

For our first post, Christopher Havens joined us for an interview exploring his journey.

We recently secured approval for a pilot program in Australia's largest prison! This makes our coding app available for incarcerated people. Before, learning programming was functionally impossible: imagine learning how to code without being able to run and compile your code!
