Credit: Smithsonian Institution Archives Heisuke Hironaka, a prominent figure in algebraic geometry, was renowned for his landmark 1964 proof of the “resolution of singularities”. His work provides a way to unravel complicated phenomena in geometric objects, such as cusps, spikes and self-intersections. This fundamental result is a standard ingredient in research across a wide swathe
