Even the most detached of physicists can hardly have failed to observe in his local shops during the last two years the appearance of a new component, the liquid crystal display. There is now a move into the laboratory, with multimeters and other instruments incorporating liquid crystals, and this may stimulate the more curious to seek out a book which explains the complex optical properties of these strange materials in terms readily appreciated by the nonspecialist.
