Hong Wang Breaks New Ground with 2026 Fields Medal win
Hong Wang and collaborator Joshua Zahl proved the 3D Kakeya set conjecture, a landmark result at the crossroads of harmonic analysis, geometric measure theory, and PDE, earning Wang the 2026 Fields Medal—the third woman to win the prize. The award caps a remarkable journey from Guilin to France, MIT, and NYU, and showcases Wang’s use of multiscale analysis and innovative “sticky” Kakeya techniques to rule out counterexamples, reshaping the field and pointing to future work on higher-dimensional Kakeya problems.

Reviving Geometry's Classic Challenges with New Math
A team of mathematicians has revived interest in enumerative geometry by applying a decades-old theory called motivic homotopy theory to count solutions across various number systems, providing new insights and raising intriguing questions about the fundamental nature of numbers and geometric objects.
New Method Unravels Knot Measurement Simplicity
Mathematicians have disproved a long-standing conjecture in knot theory by finding a counterexample that shows the unknotting number is unpredictable, revealing greater complexity in the study of knots than previously thought.
Student Resolves Long-Standing Addition Limit Issue
A graduate student at the University of Oxford, Benjamin Bedert, has solved a long-standing problem about the limits of addition related to sum-free sets, confirming that in any set of integers, there exists a large sum-free subset, advancing understanding in a fundamental area of mathematics originally posed by Paul Erdős in 1965.
"Predicting Prime Numbers: A Groundbreaking Breakthrough"
Researchers at City University of Hong Kong and North Carolina State University have made a groundbreaking discovery in prime number theory, challenging the long-held belief that prime numbers are unpredictable.

Mathematicians, including Iosif Polterovich and his collaborators, have proven a special case of George Pólya's 70-year-old conjecture in spectral geometry, concerning the estimation of the frequencies of a round drum or the eigenvalues of a disk. This achievement, published in Inventiones Mathematicae, has theoretical value and potential applications in computational mathematics and numerical computation. The researchers' success highlights the universality of mathematics and the pursuit of elegant solutions with practical implications.
"Discovery: Decimal Point Found in 1440s Italian Merchant's Notes"
The use of the decimal point in mathematics dates back further than previously thought, with a new paper tracing it back to the work of Giovanni Bianchini in the 1440s. Bianchini, a Venetian merchant and administrator, used the decimal system in his calculations in spherical astronomy and metrology, introducing the notation of a little dot to separate whole units from the fractional part. This notation was later adopted by influential mathematician astronomers such as Clavius and Regiomontanus, shaping the development of mathematical notation and paving the way for the widespread use of the decimal point.
"Discovery: Decimal Point Found in 1440s Merchant's Notes"
Math historian Glen Van Brummelen discovered a decimal used to indicate tenths of a number in a 15th-century treatise, challenging the belief that German mathematician Christopher Clavius was the first to use decimals in a 1593 treatise. The treatise by Venetian merchant Giovanni Bianchini, using a base-10 system, marked a significant advancement in calculations, potentially influencing Clavius's work. This finding sheds new light on the history of decimals and their early usage in mathematical calculations.
