Scope of the conference: Based on the process of random movement in widely varying scales from the molecular up to the macroscopic and even cosmic level, diffusion is the key to describe spreading phenomena in many different areas. Following the motto Diffusion Phenomena Moving People, the organizers' aim was to bring together dedicated scientists from all related disciplines such as engineering, physics, chemistry, sociology, ethnology, medicine, linguistics, etc. and to stimulate the interdisciplinary approach by learning about the astonishingly similar patterns of spreading phenomena.
