STATPHYS25, the 25th International Conference on Statistical Physics of the International Union for Pure and Applied Physics (IUPAP) is to be held in Seoul National University, Seoul, Korea, from July 22 to 26, 2013. In the STATPHYS tradition, starting in Florence, Italy, in 1949, this Conference is aimed at providing a current overview of the general field of Statistical Physics and to foster interaction among all scientists involved in all research topics in this area. The community of research scientists in Statistical Physics meets every three years at the STATPHYS Conferences, organized under the sponsorship of the IUPAP. These are the largest general meetings in Statistical Physics and the occasion when both the latest advances of this science in its traditional domain and new developing trends in other related fields are examined. Recent STATPHYS meetings were held at Cairns, Australia (2010), Genova, Italy (2007), Bangalore, India (2004), Cancun, Mexico (2001), Paris, France (1998), Xiamen, China (1995), Berlin, Germany (1992), and Rio de Janeiro, Brazil (1989). The organizers have provided assurance that STATPHYS25 will be conducted in accordance with IUPAP principles as stated in the ICSU-Document "Universality of Science" (sixth edition, 1989) regarding the free circulation of scientists for international purposes. In particular, no bona fide scientist will be excluded from participation on the grounds of national origin, nationality, or political consideration unrelated to science.
