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 ...

2D shapes can be described by their sides, their angles and their symmetry. The sides might be equal in length and some might be parallel. The angles could be right angles, but sometimes they are ...

The shapes can seem to appear out of nowhere: an undulating S-like spiral streaking across the European skies or a glowing orb trailing above the North American coast. Such strange light shows ...

MYRTLE BEACH, S.C. — As rain and snow continue to fall in New York, several GLOW baseball and softball programs escaped south. The trip provided teams with a clear path for play that was unavailable ...

This file includes redefinitions of the core modules to work with attachment, and functional forms of those modules that produce paths. You can create regular polygons with optional rounded corners ...
