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

From math to biology Mathematically, the two-thirds law is a no-brainer. Consider a bog-standard cube: if you increase the length of one side by, say, x times, then the surface area will increase ...

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 ...

In spite of this strong experimental evidence, scaling laws on the strength of solids usually ignore geometry and are studied by applying mechanics (see ref. 5): in particular, fracture mechanics ...
