Math’s astir prestigious prizes were announced coming astatine nan International Congress of Mathematicians successful Philadelphia. Following a lively brass-band capacity by nan West Philadelphia Orchestra successful a monolithic auditorium astatine nan Philadelphia Convention Center, nan president of nan International Mathematical Union bestowed nan prizes to 4 mathematicians for activity ranging from nan mentation of knots to nan mobility of fluids.

The Fields Medals went to Hong Wang of New York University and France’s Institute of Advanced Scientific Studies (IHES), Yu Deng of nan University of Chicago, John Pardon of Stony Brook University and Jacob Tsimerman of nan University of Toronto.

In nan awards’ 90-year history, Wang is only nan 3rd female to triumph one, aft mathematicians Maryam Mirzakhani and Maryna Viazovska successful 2014 and 2022, respectively. Wang and Deng correspond nan prizes’ only Chinese-born recipients too mathematician Shing-Tung Yau, who won a Fields Medal successful 1982.

The awards, often referred to arsenic math’s Nobel Prizes, are named for John Charles Fields, a Canadian mathematician who led nan push for their creation successful nan 1920s arsenic a measurement to bring nan world mathematics organization together. But dissimilar nan Nobels, they are only bestowed each 4 years, and starting successful 1966 only spell to researchers who little than 40 years old.

Hong Wang

When Wang roseate to speak during a symposium astatine nan Institute for Advanced Study successful Princeton, N.J., this past February, she opened pinch a characteristic statement of humility. “Thank you for having me; it’s a awesome honor,” she said. “Especially erstwhile I saw nan speaker list, I thought, ‘Maybe I shouldn’t speak.’”

But nary 1 successful nan rapt assemblage shared Wang’s opinion. At property 34, her activity astatine nan interface of 2 mathematical fields—taking collections of wavelike equations and utilizing them to research really shapes capable space—had already transformed some subjects. In particular, a 2025 impervious of nan three-dimensional Kakeya conjecture that she co-authored pinch mathematician Joshua Zahl marked a triumphant extremity to what had been a fervent, field-defining 50-year search.

Now Wang possesses nan eventual qualification for immoderate database of mathematical greats: a Fields Medal.

The Kakeya conjecture is nan reply to a mathematical game: swirl your pencil astir successful nan aerial truthful that it points successful each guidance precisely erstwhile while besides swiveling it done arsenic small abstraction arsenic possible. Wang and Zahl proved a basal limit to really mini that abstraction tin perchance be.

“She solved nan ‘holy grail’ problem,” says Nets Katz, a mathematician astatine Rice University, adding that this is only 1 of nan accomplishments that “has made her a cardinal figure” successful nan area. Wang’s Fields Medal, he says, “is good deserved.”

Wang remembers being excited erstwhile Mirzakhani became nan first female to triumph a Fields badge successful 2014. But for illustration it was for the precocious Mirzakhani, who was a reticent nationalist figure, this facet of nan accomplishment is somewhat secondary to Wang. “I didn’t deliberation excessively overmuch astir it,” she says.

Yu Deng

Informed softly successful January that he’d won a Fields medal, Deng fled his University of Chicago office, spending nan adjacent fewer days stepping nan shores of Lake Michigan to calm his nerves. But past he went backmost to work. “You conscionable enactment arsenic if thing happened,” he says.

In 2024 and 2025 he and his co-authors released a bid of gargantuan papers that amounted to an unprecedented accomplishment successful mathematics and physics. The mobility of fluids has ever seemed contradictory. Microscopically, a fluid is simply a chaotic jumble of molecules bouncing disconnected 1 different for illustration billiard balls. But macroscopically, it follows laws of mobility arsenic if it was 1 continuous whole.

Mathematicians had tried—and mostly failed—for much than a period to formally reconcile really fluids could behave successful these 2 chopped ways. Deng’s grant is for changing that. He and his collaborators proved that nan equations that picture fluids connected different scales are really 1 and nan same.

“It’s a genuinely spectacular, singular result,” says Scott Armstrong, a mathematician astatine N.Y.U. It’s difficult to ideate a much deserving recipient, Armstrong adds, and he expects Deng’s mathematical tally to continue. “It would person been a disaster had he not won.”

With today’s awards, Deng and Wang person now tripled nan full number of Chinese-born Fields Medalists. This reflects China’s decades of finance successful mathematics education, which has led to a caller harvest of talented young mathematicians populating nan apical universities. “I’m moving mostly conscionable arsenic myself,” Deng says, “but I’m besides happy that I’m 1 of nan first of this caller procreation to get this recognition.”

John Pardon

If a Fields Medal is an grant for nan mathematically precocious, it’s difficult to ideate a amended fresh than Pardon. In 2010 he was conscionable a 21-year-old undergraduate astatine Princeton University erstwhile his activity successful knot mentation ensured nan full mathematics world learned his name.

Knot mentation is astir each nan different ways a portion of drawstring tin beryllium tied up, pinch its 2 loose strands glued together aft nan tying. These myriad forms are famously difficult to sort—two knotted-up strings mightiness look wholly different yet, done elaborate manipulations, beryllium made to match. So mathematicians effort to travel up pinch foolproof methods for differentiating them.

One of these is “distortion”: a measurement of measuring really difficult a knot is to traverse. It gauges really agelong it would return an ant, for instance, to crawl from 1 constituent on nan drawstring to another—compared pinch a grasshopper that could simply leap betwixt them.

“John showed that, for a definite series of knots, nan distortion became arbitrarily large,” says David Gabai, a mathematician astatine Princeton. “This simply stated problem attracted overmuch liking among mathematicians during nan erstwhile 25 years.”

“I was happy astir it,” Pardon recalls of toppling this mathematical Goliath arsenic a specified equation-slinging undergraduate. But successful hindsight, he says, he should’ve been moreover happier. “It’s difficult to cognize astatine nan clip really overmuch value a fixed solution will have.” This is simply a sentiment Pardon has knowledgeable galore times since: successful postgraduate schoolhouse and beyond, he went connected to conquer different awesome conjectures covering different areas of geometry.

Jacob Tsimerman

Tsimerman loved mathematics from an property astatine which astir children look scarcely alert it moreover exists. “My parents recognized, by nan clip I was three, that I was ace into it,” he says. “I ne'er really considered not being a mathematician.”

His grandfather would springiness him elemental mathematical puzzles to activity with, and erstwhile his mother noticed his early fascination pinch antagonistic numbers, she offered him her precocious schoolhouse mathematics textbook to thumb through. “It conscionable became for illustration recreation for me, agelong earlier it was a career,” Tsimerman says.

In 2021 he and 2 collaborators proved nan André-Oort conjecture, which concerns nan section of mathematics that seeks solutions to equations for which each nan variables are full numbers. But this conjecture leaves elemental equations and full numbers behind; it seeks typical points connected rarified objects called “Shimura varieties,” which are sometimes (but not always) solutions to equations. This is esoteric stuff, but Shimura varieties are hugely important successful mathematics today, and nan conjecture gives mathematicians an unprecedented grip connected their elaborate structure.

“Jacob is simply a superb mathematician,” says his longtime collaborator Jonathan Pila of nan University of Oxford. “I person seen his brilliance and resourcefulness astatine first hand—he is besides a very easygoing character.”

The André-Oort conjecture is conscionable 1 of Tsimerman’s mathematical feats. He’s besides made important contributions successful “Hodge theory,” an area that relates to 1 of the 7 Millennium Prize Problems—meaning its solution has a $1-million reward.

Although a Fields Medal’s monetary worth is modest—just nan 14-karat-gold badge itself positive 15,000 Canadian dollars—the prestige it bestows is invaluable. Tsimerman wants to usage his stock to nonstop much attraction to a caller area: artificial intelligence. “I deliberation that location are large changes coming to our world, and I want group to attraction connected that,” he says. “One of nan galore scary things astir AI is that we don’t really understand nan strategy very well.” Tsimerman hopes axenic mathematics tin alteration that.
