The Seventeenth Jerusalem Symposium focused on dynamics on surfaces, a subject of interest in the areas of chemistry, physics and material sciences. The Symposium reflected the high standeds of these distinguished scientific meetings, which convene yearly at the Israel Academy of Sciences and Humanities to discuss a specific topic in the broad area of quantum chemistry and biochemistry. Molecule-surface dynamics constitutes a fast developing, current, research area. The main theme of the Symposium was built around a conceptual framework for the elucidation of the chemical and physical aspects of atomic and molecular scattering off surfaces, surface transport, surface reaction dynamics and radiative interactions on surfaces. The interdisciplinary nature of this research area was emphasized by intensive and extensive interactions between scientists from different disciplines and between theory and experiment. HeLd under the auspices of the Israel Academy of Sciences and Humanities and the Hebrew University of JerusaLem, the Seventeenth JerusaLem Symposium was sponsored by the Institut de BioLogie Physico- Chimique (Fondation Edmond de RothschiLd) of Paris. We wish to ex- press our deep thanks to Baron Edmond de Rothschild for his continuous and generous support, which makes him a true partner in this important endeavour. We would aLso like to express our gratitude to the Admi- nistrative Staff of the Israel Academy, and in particular to Mrs. AvigaiL Hyam, for the efficiency and exceLLency of the LocaL arrangements.
