In science, sociophysics is the study of social phenomena from a physics perspective. The subject seems to deal with thermodynamics in part; albeit, the majority of theories in this field seem to be on statistical extrapolations or phase transition models.
A noted researcher in the field is physicist Serge Galam claims that he has been in the field of sociophysics since the late 1970s.  A noted researcher in this field is Canadian political scientist Paris Arnopoulos and his 1993 book Sociophysics, in which he speculates on heat, pressure, temperature, entropy, and volumes of societies. 
At the 2008 international workshop on socio physics, at Torino, Italy, the focus was on the statistical physics modeling of large scale social phenomena, such as opinion formation, cultural dissemination, the origin and evolution of language, crowd behavior, social contagion; where it was stated that previous years had witnessed the attempt to study collective phenomena emerging from the interactions of individuals as elementary units in social structures. The workshop worked to promote effective cooperation between physicists and social scientists.
