Day At Cern A Guided Tour Through The Heart Of Particle Physics

Day At Cern, A: Guided Tour Through The Heart Of Particle Physics

'This brief book offers an interesting, fun, and widely accessible first-person tour of CERN, the European Center for Nuclear Research, the largest particle physics laboratory in the world. The facilities at CERN include the Large Hadron Collider (LHC), a 27-kilometer particle accelerator that straddles the border between Switzerland and France. The LHC was famously used to discover the Higgs boson, a long-sought fundamental particle. Physics historian Depambour (University of Paris) is enthusiastic about all aspects of CERN, especially its role as an agent for peace and international cooperation. The book focuses mainly on the physical layout of the CERN campus and its experimental facilities, but Depambour also includes an introduction to the standard model of particle physics and a history of the search for the Higgs boson. Supporting illustrations and interviews help convey the atmosphere and culture of CERN. The book can be read and enjoyed by virtually anyone interested in modern science, starting with students currently in high school. It will also be welcome as a useful orientation for undergraduates and graduate students whose research interests might eventually take them to CERN. Summing Up: Highly recommended. All readers.'CHOICEWhat lies within CERN's entrails? What is the path followed by the particles that are accelerated before they collide? What does the ATLAS detector look like? Does research at CERN find applications in everyday life?From the accelerator control room to the huge Computing Centre, via the auditorium where the discovery of the Higgs boson was announced in July 2012, I invite you to experience for one day an immersion in the world of research in particle physics! Discovering emblematic installations at CERN, walking through the places where people spend every working day, meeting with researchers in various fields, descending into the ATLAS cavern ... Our visit, whose path will mimic that of the particles during their journey, will be full of anecdotes and surprises.Follow me for a guided tour of CERN, the largest scientific collaboration in the world!

History Of Particle Theory: Between Darwin And Shakespeare

History of Particle Theory fills an important gap existing in the literature by discussing the impressive progress in understanding the elementary particles out of which all everyday objects are made. Most of this progress has happened in the last seventy years after the theory of quantum electrodynamics (QED) was perfected as an extremely accurate description of electromagnetic interactions. This astonishing sequence of discoveries was made hand in hand between theory and experiment. This book concentrates only on theory where giant steps were made by a series of exceptionally creative physicists, and this is portrayed as an essential part of the broader spectrum of human knowledge and culture, which is constantly being similarly extended by the creative individuals such as the two mentioned in the subtitle, Between Darwin and Shakespeare, who both significantly changed Western Civilization by ideas in Biology and in English Literature respectively.In the last forty years, the standard model has been confirmed again and again as the correct description of elementary particles up to energies of a thousand times the proton mass. In the discussion of particle theory and theoretical physics in general, the book starts from well over two thousand years ago, going back to the ancient Greeks such as Democritus and Archimedes, until the 17th century, when the extraordinary intellect of Newton changed everything by demonstrating that not only objects in the laboratory but also heavenly bodies are governed by mathematical equations. There followed what can be called Darwinian evolution in theoretical physics, survival of the fittest theories, by loose analogy with the origin of biological species.The present standard model of particle theory surely cannot be the final word because it contains far too many free parameters. The book contains a penultimate chapter discussing a number of such open problems which exist in particle theory. There is then a closing chapter, not related to the rest of the book, providing a series of quotations written in the 16th and 17th centuries by Shakespeare and here applied to particle theory. The inclusion of this is based on our premise that particle theory is just one out of several opportunities for exceptional human creativity.
