From four-dimensional hexagons to the mind-bending amplituhedron, geometrical shapes are wilder than we learn at school - and ...

A new study shows that like humans, crows can recognize geometric regularity, making them the first nonhuman animal known to have this ability. Squares, triangles, circles - these geometric shapes ...

“They’re the natural language for geometric objects.” They’re also tough to define. Talk to a computer scientist, and they might tell you that a tensor is an array of numbers that stores important ...

Crows in a lab were able to distinguish shapes that exhibited right angles, parallel lines, and symmetry, suggesting that, like humans, they have a special ability to perceive geometric regularity.
