The latest installment of the long-standing mathematical challenge series, Puzzle Corner, has been released for the September/October 2026 period, according to MIT Technology Review. The publication maintains a tradition of editorial engagement that spans six decades.

Responsibility for the current edition rests with the Puzzle Corner Puzzle Crew, known as PC 2. This group consists of Michael S. Branicky, ScD ’95, alongside Edward Faulkner ’03, MEng ’04, and Abe Kunin ’03. The current issue provides necessary solutions to the problems presented in the May/June edition. Readers looking to participate in the ongoing challenge are directed to submit their solutions and prospective problems to the editorial team at puzzlecorner@technologyreview.com by October 1.

Historical Editorial Timeline

Original editor emeritus Allan Gottlieb ’67 initiated the column in 1966. The archives of the column are split across two distinct digital locations: historical materials documenting the project through 2022 are hosted via New York University at cs.nyu.edu/~gottlieb/tr, while more recent entries are maintained directly on the MIT Technology Review portal.

Why It Matters

Technical publications often serve as repositories for institutional culture, and the longevity of the Puzzle Corner highlights the intersection of academic rigor and recreational mathematics. While modern media focuses on fast-cycle algorithmic content, the maintenance of such long-form, logic-based challenges provides a measure of intellectual continuity for engineering and science alumni. By preserving these archives, institutions demonstrate the value of cognitive endurance, which remains a key metric for talent recruitment in high-complexity sectors like software engineering and theoretical physics, where the ability to solve non-linear problems is essential for professional advancement.
