When physical chemist Richard Williams applied an electric field to a thin layer of a nematic liquid crystal at 125 °C, he observed the formation of a regular pattern that he called domains (now known as Williams Domains).
Când chimistul-fizician Richard Williams a aplicat un câmp electric unui strat subțire de cristal lichid nematic la 125 °C, el a observat formarea unui model regulat pe care el l-a numit „domeniu” (astăzi denumit „domeniu Williams”).
