Mathematician Matt Parker celebrates the year 2025, a date he has anticipated for a decade because it marks the year he will turn 45, the square root of the year. He unveils a deeper mathematical property: 2025 is the square of a triangle number. This discovery led to a collaboration with the firm Jane Street to create the “Partridge Puzzle,” a massive physical installation based on this unique numerical relationship.
