The Kakeya Conjecture, proposed by Japanese mathematician Sōichi Kakeya in 1917, has finally been proven in 3D space after 108 years. The proof, by Hong Wang (NYU) and Joshua Zahl (UBC), reshapes harmonic analysis and won Wang a 2026 Fields Medal.
In 2025, French and British mathematicians proved a 40-year-old conjecture about the "spectral gap" of hyperbolic surfaces. Building on the late Maryam Mirzakhani's research, this discovery has potential applications in quantum chaos and efficient communication network design. We explain this complex mathematical world in accessible terms.
In 2025, a team of American mathematicians partially solved Hilbert's sixth problem, unresolved for 125 years. This groundbreaking achievement mathematically proves how microscopic particle motion gives rise to macroscopic fluid laws, shedding new light on the mystery of the "arrow of time."
On December 22, 2025, MEXT presented a plan to a Central Council for Education working group: fold AI and data science fundamentals into Mathematics I, the mandatory high school course, via two new units, and dissolve the Mathematics A/B/C split into a single subject. From the 2032 curriculum, every student takes it, humanities track included.
