Cern, “Accelerating Science” European Organization for Nuclear Research (CERN) is a laboratory campus of high energy physics. The basic purpose of all experiments conducted here is searching for the basic building stones of matter. Moreover, decades of experiments at CERN are working towards understanding all of the different forces of nature within one framework which is actually one of the ultimate goals of physics. 113 countries, 608 universities and 12000 researchers take part here. It is on the borderline between France and Switzerland, some laboratories are on France but most of them are on Swiss part. the most powerful magnifying glass because they are smaller than the wavelenght of the “visible light”. So, how can we ‘look’ inside the atom? To find out what something is made of you might A) look at it B) heat it and see what happens C) smash it by a strong force √ So that is why initially we call particle accelerators as “atom smashers”. • In huge accelerators we speed particles and smash them into one another. By this way we are creating – for a brief moment – in a small region of space – an intense concentration of energy which replicates the nature of the universe as it was within original Big Bang. The particles discovered experimentally or defined theoritically are shown in the figure. PHYSICS DEPARTMENT What Are We Made Of? The drive of high-energy physics is curiosity; the desire to know • what we are made of • where it came from • why the laws of the universe are so finely balanced that we have evolved2. The fundamental structure of the atom is beyond real imagination! Particle physics tries to show how matter is built and explain where it all come from. But we will never be able to see the particles even with THE CLAPPER 2014 - 2015 45
