This volume is a collection of the Nobel lectures delivered by the Nobel laureates, together with their biographies and the presentation speeches by Nobel Committee members for the period 2011-2015. The criterion for the Physics award is to the discoverer of a physical phenomenon that changed our views, or to the inventor of a new physical process that gave enormous benefits to either science at large or to the public. The biographies are interesting to read and the Nobel lectures provide detailed explanations of the phenomena for which the laureates were awarded the Nobel Prize.
