Liquid Crystals are a state of matter that have properties between those of conventional
liquid and those of a solid crystal. Thermotropic liquid crystals react to changes
in temperature or, in some cases, pressure. The reaction of lyotropic liquid crystals,
which are used in the manufacture of soaps and detergents, depends on the type of
solvent they are mixed with. Since the accidental discovery of the chiral nematic
(ordered) phase in 1888 many liquid crystal phases have been found, sometimes by chance
and sometimes by design. The existence of one such phase was predicted by Freiser
in 197
