Hong Wang, a mathematician at New York University, has been named one of the winners of the 2026 Fields Medal, making her only the third woman to receive the prestigious award in its 90-year history. The Fields Medal is considered the highest honor in mathematics and is awarded every four years to mathematicians under the age of 40. Wang helped solve a long-standing problem in geometry that had puzzled experts for decades. Her work has been hailed as a major breakthrough in the field. The announcement was made on Tuesday, though the official ceremony will take place later this year. Wang joins Maryam Mirzakhani, who won in 2014, and June Huh's co-winner? Actually, Huh is male. The first woman was Mirzakhani in 2014, and the second was Karen Uhlenbeck? Wait, Uhlenbeck won the Abel Prize, not Fields. Actually, the second woman to win the Fields was Maryna Viazovska in 2022. So Wang is the third. But we should not add that unless source says. The source says third woman, so we can state that. We'll keep it simple. The article should be 200-250 words. Let's write.
