Informal learning is the unofficial, unscheduled, impromptu way most of us learn to do our jobs. Informal learning is like riding a bicycle: the rider chooses the destination and the route. The cyclist can take a detour at a momentâs notice to admire the scenery or help a fellow rider.
The name mica is derived from the Latin micare, which means to glitter or also to shine. Mica is a naturally occurring group of silicate minerals that has a perfect basal cleavage, easily splits into thin luminae, and is most often translucent in appearance.
All are monoclinic, with a tendency towards pseudohexagonal crystals, and are similar in chemical composition. The nearly perfect cleavage, which is the most prominent characteristic of mica, is explained by the hexagonal sheet-like arrangement of its atoms. The word mica is derived from the Latin word mica, meaning a crumb, and probably influenced by micare, to glitter.
