Playing with light and a crystalA crystal or crystalline solid
is a solid material, whose constituent atoms, molecules, or ions are arranged in an orderly repeating pattern extending in all three spatial dimensions. The scientific study of crystals and crystal formation is crystallography. The process of crystal formation via mechanisms of crystal growth is called crystallization or solidification. The word crystal is derived from the ancient Greek word κρύσταλλος (krustallos), which had the same meaning, but according to the ancient understanding of crystal. At root it means anything congealed by freezing, such as ice.[1] The word once referred particularly to quartz, or "rock crystal".
Most metals encountered in everyday life are polycrystals. Crystals are often symmetrically intergrown to form crystal twins.
Hi my friends,

And thanks again to Carol for giving it to me.
Today is a beautiful day again in Florida, the temps are in the 70's and now we are heading out to the beach. Hubby need some fresh air to breath - and me too....smile...
