This book deals with randomly moving objects and their spreading. The objects considered are particles like atoms and molecules,
but also living beings such as humans, animals, plants, bacteria and even abstract entities like ideas, rumors, information,
innovations and linguistic features. The book explores and communicates the laws behind these movements and reports about
astonishing similarities and very specific features typical of the given object under considerations. Leading scientists in
disciplines as diverse as archeology, epidemics, linguistics and sociology, in collaboration with their colleagues from engineering,
natural sciences and mathematics, introduce the phenomena of spreading as relevant for their fields. An introductory chapter
on "Spreading Fundamentals" provides a common basis for all these considerations, with a minimum of mathematics, selected
and presented for enjoying rather than frustrating the reader.
