In geometry, an object exhibits symmetry if it looks the same after a transformation, such as reflection or rotation. Symmetry is important in art, math, biology and chemistry.

This paper formulates the problem of measuring bilateral symmetry of objects analytically for landmark data, and develops various new testing procedures and exploratory data analyses. The development ...

Kaleidoscope mirror symmetry inspires new design for optical tools, technologies Using multiple-axis symmetry inspired by kaleidoscopes, new polarization designs can control spin angular momentum ...
