The 2026 Fields Medal, one of the world’s most esteemed accolades in mathematics, has been awarded to four groundbreaking young researchers, including esteemed mathematician Mr. Wang Hong. Remarkably, she is the third woman to achieve this honor in the 90-year history of the award.
The Fields Medal is conferred every four years to a mathematician under the age of 40 for exceptional discoveries. It is presented by the International Mathematical Union. The winners were announced on July 23, with Professor Wang recognized for her groundbreaking work forecasting the movement of a needle in 3D space.
The 2026 Fields Medal winners also feature: Yu Deng from the University of Chicago, recognized for connecting microscopic and macroscopic gas descriptions. John Purdon, a professor at Stony Brook University, acclaimed for resolving significant issues in topology and geometry. Lastly, Jacob Zimerman from the University of Toronto, who has advanced powerful new methods in algebraic geometry and addressed longstanding mathematical enigmas.

Ms. Wang now joins a notably small group of women to receive the Fields Medal. Iranian mathematician Mariam Mirzakhani was the first in 2014, followed by Ukrainian mathematician Marina Wiazovska. Until Mirzakhani’s win, no woman had received the award for nearly 80 years.

Mr. Wang is known for her work on the Kaketani conjecture, focusing on the spatial requirements for a needle to orient in all three dimensions. This mathematical challenge has captivated researchers for nearly 50 years.
Wang and her collaborator Joshua Saar demonstrated a precise balance between the slenderness of the tubes representing the needle and the overall space they possess. Their approach primarily employs harmonic analysis, a field devoted to understanding complex shapes and signals through simplification.
Receiving the award was not an immediate elation for Wang. After months of scrutinizing their lengthy evidence, she initially worried it might overshadow their findings. Nonetheless, their work has been likened to a “once in a century” achievement, leading to the prestigious Fields Medal accolades, as highlighted by Quanta Magazine.
