A polygon is a 2D shape with straight sides that meet at vertices. Polygons have names that show the number of sides they have. A three-dimensional (3D) shape is a solid shape. 3D shapes have ...

A 2D shape could have line symmetry or rotation symmetry, or both! 3D shapes are described by their faces, edges and vertices. The faces can be the same shape or different, and a 3D shape could ...

Over the years, mathematicians found that the twisted shapes exist in dimensions 2, 6, 14, 30 and 62. They also showed that ...

Researchers at Westlake University have disclosed a two-dimensional (2D) mechanically interlocked polymer (MIP) that mimics medieval chainmail at the molecular scale. This micrometer-scale 2D ...

CLCEs are soft, rubber-like materials that shift color when under stress. This ability comes from their spiral-shaped inner ...

According to the National Institute of Standards and Technology (NIST), researchers have found special atomic patterns called quasicrystals in 3D printed aluminum alloys ... is made of a few identical ...
