CRYSTALS

Someone say "crystal" and people often imagine something beautiful, perfect and rare. In reality any body around us is a crystal. The exceptions are plants, animals, water and the atmosphere.

Crystallography is referred to as ''the most difficult and the most useless of sciences''. But it is one of the most important branches of natural science. Mathematics closely relates to crystallography.

Now the method of neutron diffraction comes into wide use in the field of crystal analysis. Crystals offer a simple way for transformation of one kind of energy into another one. Research into the strength of crystals is of special interest. All the metals and alloys constitute a collection of tiny crystals. The more perfect the crystals, the higher the strength of the metal. This means that it is possible to obtain crystals of the necessary strength.

Nowadays most of crystals are artificial. For example, engineers grow rock crystals at factories in a quantity far larger than that are at the nature. Ruby crystals have numerous applications. Ruby rods form the core of lasers. Engineers and scientists pay much attention to the future of crystal application.

crystallography - кристаллография to be referred to as - называться ruby - рубин
