Gamma Ray Bursts (Grbs)
15 Epilogue Roger D. Blandford Kavli Institute for Particle Astrophysics and Cosmology, Department of Physics and SLAC National Accelerator Laboratory, Stanford University, Stanford, CA 94305, USA The preceding fourteen chapters have been written at a good time to take stock of the field of Gamma Ray Bursts (GRBs). The extraordinary discov- eries made over the last decade or so about a phenomenon that has been around for over four decades seem to have attained a mature state. Thou- sands of bursts have been observed, classified and followed up and it is now the special and rare cases, that are extreme by some important measure, that are most likely to advance our understanding as radically new γ−ray and X-ray observing capabilities are at least a decade away. On the theoret- ical front, some prescient inferences have been vindicated, phenomenological models that are usable by observers have been developed, and simulation has made great strides. The greatest challenge is to explore the underlying physical processes in much more detail and this is likely to require a new generation of high performance computers. Nonetheless, the GRB pace of discovery like much of contemporary astrophysics will likely exceed that in most other subfields of physical science. I was asked to write a critique of where we are today and what I think will be the major developments going forward. My qualifications for this task are not promising. I have probably contributed most to the study of a high energy γ−ray stellar phenomenon unintentionally in the context of trying to explain variability of the lowest frequency radio emission from active galaxies and my largest attempt to work on what I thought was relevant turned out to be only applicable, at best, to X-ray bursting neutron stars. -

The Center for Astrophysics Science Strategic Plan
Harvard-Smithsonian Center for Astrophysics Science Strategic Plan Executive Summary Mission Statement "The mission of the Harvard-Smithsonian Center for Astrophysics is to advance our knowledge and understanding of the Universe through research and education in astronomy and astrophysics." Introduction At the Center for Astrophysics we engage in forefront research in many different ways, from small individual projects to research centers to the utilization and operation of unique major ground- and space-based facilities. We excel as observers, theoreticians, instrumentalists and laboratory experimentalists. Our research spans the breadth of the electromagnetic spectrum, helping to create the distinctively fertile research environment that is the underpinning of our success. Our vision is to remain the leading center in multi-wavelength observing while strengthening our theoretical, computational and laboratory astrophysics efforts. How best to sustain and strengthen our Center is a challenging matter. The opportunities for breakthroughs in our field are numerous – this is the new “golden age” of astronomy – and they beckon our full participation. The Science Strategic Planning Committee (SSPC) was charged by the Director with determining which new facilities and programs will best suit our distinctive competencies. For the past year this committee, comprised of members from the scientific divisions, crafted this strategic plan to accomplish two objectives: 1. identify those new facilities and programs that tackle the most important science goals of our generation, make maximum use of our expertise in these areas, and promise the most significant benefit to our research, and 2. establish an appropriate balance between these few strategic projects and the important research carried out by our colleagues as individuals and in small groups. -

A History of Fear in British Culture, Identifying the Discursive Formations That Have Shaped the Apocalyptic Discourse in Britain Over the Last 120 Years
The idea of apocalypse has a long tradition in the history of civilization. Secularized speculations about the end of the world have been a part of public discourse in Britain ever since the 19th century. This study investigates fiction about the potential end of humankind, written and produced by British writers and filmmakers from the 1890s to the beginning of the 21st century. Martin Hermann argues that British apocalyptic fiction is deeply embedded in the cultural context of its respective era. Applying ideas from Michel HERMANN Foucault’s The Archaeology of Knowledge and analyzing works by H. G. Wells, John Wyndham, John Brunner, Stephen Baxter and other, less remembered authors of speculative fiction, Hermann traces a history of fear in British culture, identifying the discursive formations that have shaped the apocalyptic discourse in Britain over the last 120 years. · · Fear A History of ‘Working through an impressively wide range of examples, Hermann draws out the larger trends and currents of this enduring mode of writing.’ ADAM ROBERTS Royal Holloway, University of London Author of several acclaimed SF novel British Apocalyptic Fiction, 1895 A History of Fear British Apocalyptic Fiction, 1895 –2011 – 2 011 MARTIN HERMANN Foreword by Adam Roberts A History of Fear British Apocalyptic Fiction, 1895−2011 The idea of apocalypse has a long tradition in the history of civilization.
