Two mathematicians have proved that a straightforward question—how hard is it to untie a knot?—has a complicated answer.

MIT researchers uncovered clear evidence of unconventional superconductivity in magic-angle twisted trilayer graphene.

Quantum mechanics has at last been formulated exclusively with real numbers, bringing a mathematical puzzle at the heart of ...

Researchers in Spain reviewed six models used to calculate incidence angle modifier (IAM) losses in photovoltaic systems. They identified the Martín-Ruiz model as the most comprehensive, as it ...
