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.
The mica group of sheet silicate minerals includes several closely related materials having nearly perfect basal cleavage. 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.
