Work

An accumulation of matter with uniform physical and chemical properties is said to be in a certain phase, such as solid, liquid or gas. Magnetism and the orientation of molecules can also give rise to different phases. Different phases are characterized by different forms of order and disorder. During the 1970s Pierre Gilles de Gennes showed how transitions from order to disorder come about, especially for liquid crystals and polymers in solution. He demonstrated that the results apply to a number of different types of phase transitions.
