Mathematicians Startled by 17-Year-Old With Uncanny Abilities

A brilliant teen who honed her skills during the COVID-19 pandemic has solved one of math's most mysterious problems — and in doing so, become a rising star. As Quanta magazine reports, fledgling mathematician Hannah Cairo was just 17 when she disproved the Mizohata-Takeuchi conjecture, a decades-old proposition — in higher math, it's common for the suggestion that something is true based on observations to become a target for challenging formalized counter-proofs — dealing with waves on surfac

Hannah Cairo: 17-year-old teen refutes a math conjecture proposed 40 years ago

Hannah Cairo was stuck on a math problem. All she could think about during those weeks was a new approach. “After months of trying to prove the result, I managed to understand why it was so difficult. I realized that if I used that information correctly, I might be able to refute the claim. Finally, after several failed attempts, I found a way to construct a counterexample [a case that does not satisfy the studied property and therefore proves it is not universally true].” Ciaro says it required

After 20 years, math couple solves major group theory problem

After the conjecture was posed in the 1970s, dozens of mathematicians tried their hand at proving it. They made partial progress — and in the process they learned a great deal about groups, which are abstract objects that describe the various symmetries of a mathematical system. But a full proof seemed out of reach. Then Späth came along. Now, 20 years after she first learned about the problem and more than a decade after she met Cabanes, the two mathematicians have finally completed the proof.
