The Math(s) Fix: An Education Blueprint for the AI Age is a groundbreaking book that exposes why math education is in crisis worldwide and how the only fix is a fundamentally new mainstream subject. It argues that today's math education is not working to elevate society with modern computation, data science, and AI. Instead, students are subjugated to compete with what computers do best and lose.

The automobile was one of the most miraculous inventions of the 20th century. It promised freedom, style, and utility. But sometimes, rather than improving our lives technology just makes everything worse. Over the past century cars have filled the air with toxic pollutants and fueled climate change. Cars have stolen public space and made our cities uglier, dirtier, less useful, and more unequal. Cars have caused tens of millions of deaths and injuries. They have wasted our time and our money.

Most of the top jobs for the future require students to have a strong foundational understanding of mathematics. Our failure to mathematically educate most students in general, and students of color in particular, is bad not only for these students individually but also for our society. In Choosing to See, Pamela Seda and Kyndall Brown offer a substantive, rigorous, and necessary set of interventions to move mathematics education toward greater equity, particularly in serving the needs of Black and Brown students, who are underrepresented and underserved as math scholars.

If you're like most people, geometry is a dimly remembered exercise you gladly left behind in the dust of ninth grade. It's plodding through a series of miniscule steps only to prove some fact about triangles that was obvious to you in the first place. That's not geometry. Okay, it is geometry, but only a tiny part, which has as much to do with geometry in all its flush modern richness as conjugating a verb has to do with a great novel. Shape reveals the geometry underneath some of the most important scientific, political, and philosophical problems we face.

Survival Math is both a personal reckoning and a vital addition to the national conversation about race. Mitchell explores the Portland of his childhood, tracing the ways in which his family managed their lives in and around drugs, prostitution, gangs, and imprisonment as members of a tiny black population in one of the country’s whitest cities. He discusses sex work and serial killers, gangs and guns, near-death experiences, composite fathers, the concept of “hustle,” and the destructive power of drugs and addiction on family.
