Searching for the highest-energy particles in nature FREE

I will briefly outline the history behind the discovery of cosmic rays and explain the early efforts to understand them. I will introduce the vast energy range involved – the most energetic have an energy comparable to Andy Murray’s first serve - and explain why we are interested in studying these particles. I will describe the detection methods and the planning, construction and realisation of the Pierre Auger Observatory in Argentina, which covers a land-area about the size of West Yorkshire and is the largest cosmic-ray detector ever built. I will explain how we measure the energy of the particles and describe our efforts to use them for cosmic-ray astronomy.
