In a remarkable new study, crows demonstrated an intuitive grasp of geometry—identifying irregular shapes without training.

Crows can recognize geometric patterns, suggesting that humans aren't unique in understanding shape structure.

W hen most people think of shapes, they imagine a triangle, a rectangle, or maybe even a fancier- sounding rhombus or ...

Crows in a lab were able to distinguish shapes that exhibited right angles, parallel lines, and symmetry, suggesting that, ...

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

Polygons are 2D shapes that have straight sides. Regular polygons have sides and angles that are all the same size. Let's recap what a polygon is with this quick video. How would you work out the ...

You can create regular polygons with optional rounded corners and alignment features not available with circle(). The file also provides teardrop2d, which is useful for 3D printable holes. Many of the ...

The particle weight is compared with the importance map at each particle interaction and at each crossing of a regular geometry boundary. A rectangular-shaped shipping cask was used for a sample ...
