Meet Bille, the name given to the world's first monostable tetrahedron—a four-faced object that will always land on the same ...

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

Now, with geometry added to the list of impressive skills that crows have to offer, it’s clear that these animals are smart in ways we’re only beginning to appreciate.

What’s more, their ability didn’t depend on familiarity. The shapes were randomly rotated and scaled. The irregular shape, called the “intruder,” changed position every trial. Yet both crows ...

In the study, they could tell the difference between shapes like stars, crescents and squares, as well as between squares and irregular figures with four sides. Researchers once thought this ...

Crows seem to understand geometry — and we thought only humans could. In a remarkable new study, crows demonstrated an intuitive grasp of geometry—identifying irregular shapes without training.

A crow’s math skills include geometry 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 ...

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

How to incorporate curvy and irregular shapes into your home décor . April 11, 2025 at 7:00 am Updated April 11, 2025 at 7:00 am . By . Amber Katz. Special to At Home in the Northwest.

Grains of lamellae with parallel orientation are characterized by irregular polygon shapes and are bounded by defect regions where the lamellae are oriented out of the plane of the film.

Among all the shapes we can construct with a compass and straightedge, regular polygons hold a special cachet. The Greeks didn’t impose arbitrary rules just to make math more challenging.

But Mahler had made an important observation by breaking the problem down into two steps. His first conjecture was that the answer is a smoothed polygon with straight edges and corners rounded with ...
