The natural science that involves the study of matter and its motion through space and time, along with related concepts such as energy and force. More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves. piezoelectricity pion Planck constant Also called Planck's constant.
In textiles, lustre or luster is a physical property that makes them appear bright, glossy, and shiny. The amount of light reflected from the surface of a fiber is referred to as its luster.
