One of the prominent research areas , which have gained a lot attention of the scientific community as well as of the general public is about the study of the basic structure of matter. ‘Elementary particle physics’ as it is called is a balancing act of theoretical predictions and experimental confirmations.The widespread attention and media coverage about latest discoveries which are being announced frequently by CERN, the best particle physics study centre in the world , is undoubtedly due to the inherent interest and curiosity of human beings to understand the framework of the world they are in. This book provides an overview of the things that are going on in the micro world, to an audience who may not be specialised in science , but are interested in understanding the study of ‘matter’ with a little effort. Special emphazis is given to ‘ particle accelarators’ section , which is the practical side of particle physics research.
