Divine Language, A: Learning Algebra, Geometry, and Calculus at the Edge of Old Age by Alec Wilkinson; 2022. Hardcover.

Decades after struggling to understand math as a boy, Alec Wilkinson decides to embark on a journey to learn it as a middle-aged man. What begins as a personal challenge―and it's challenging―soon transforms into something greater than a belabored effort to learn math. Despite his incompetence, Wilkinson encounters a universe of unexpected mysteries in his pursuit of mathematical knowledge and quickly becomes fascinated; soon, his exercise in personal growth (and torture) morphs into an intellectually expansive exploration.

In A Divine Language, Wilkinson journeys into the heart of the divine aspect of mathematics―its mysteries, challenges, and revelations―since antiquity. As he submits himself to the lure of deep mathematics, he takes the reader through his investigations into the subject’s big questions―number theory and the creation of numbers, the debate over math’s human or otherworldly origins, problems and equations that remain unsolved after centuries, the conundrum of prime numbers.
