For centuries, students have learned that in a right triangle, the square of the hypotenuse equals the sum of the squares of the other two sides. Known as the Pythagorean Theorem, this ...

A high school teacher didn't expect a solution when she set a 2,000-year-old Pythagorean Theorem problem in front of her ...

Students who made math history when they were in high school have now published new ways of proving the Pythagorean Theorem using trigonometry.

They had some success. One of the earliest AI programs could output proofs of dozens of statements in mathematical logic. Other programs followed, coming up with ways to prove statements in geometry, ...

When two mathematicians raised pointed questions about a classic proof that no one really understood, they ignited a years-long debate about how much could be trusted in a new kind of geometry.

A new math proof could help us map the inside of the Earth in unprecedented detail. Gunther Uhlmann of the University of Washington, one of Vasy’s coauthors, has been working on the problem for ...
