ICTP is sponsoring the Boltzmann Memorial Meeting. The meeting will take place on Monday 4 September at Congress Hall, Duino Castle, beginning at 10:30 a.m. Introductory remarks by ICTP Director K.R. Sreenivasan will be followed by three lectures given by Leo Kadanoff, president-elect, American Physical Society; Peter Laggner, Managing Director, Institute of Biophysics and Nanosystems Research of the Austrian Academy of Sciences, Graz; and Giuseppe Mussardo, professor of physics, SISSA. Following the talks, participants will gather at the nearby former Hotel Ples to attend a ceremony unveiling a plaque honouring Boltzmann. Giorgio Ret, mayor of Duino, and Marc Abrioux, head of school of the United World College of the Adriatic, will offer remarks at the ceremony. Austrian-born Ludwig Boltzmann, father of statistical mechanics, is widely considered one of the greatest physicists of the late 19th and early 20th centuries. He took his life while on vacation with his wife and daughter in Duino on 5 September 1906.
