In the winter of 1991, with the baggage of several spectacular relationship failures, a keen eye for observing the absurdities in others, a cavalier disregard for the accepted conventions of professional journalism, and a light lunch consisting of a sandwich, some chips and a plastic cup of chocolate pudding, author J. Broad set out to find those little moments that make life the world's greatest reality show. After several years of observing, and muttering and nodding to himself, someone finally suggested that he write some of them down. A collection of these commentaries became Observations From A Broad. In a series of anecdotal columns written over the past 13 years, the author points out the bizarre, celebrates the ironic and occasionally does it in rhyming couplets (and often in parentheses). Follow J. as he leads you through his imagination while searching for the missing letters in his name. Buckle up as he breaks up with his car. Sit in the bleachers as he registers a truly abysmal record with the fairer sex. Peer through the peephole as he demonstrates the decision-making process necessary before holding a door. You'll be glad you did.

EarthScope is a major science initiative in the solid-earth sciences and has been described as "a new earth science initiative that will dramatically advance our physical understanding of the North American continent by exploring its three-dimensional structure through time". The initiative proposes to cover the United States with an array of instruments created to reveal how the continent was put together, how the continent is moving now, and what lies beneath the continent. The initiative is made of four components, three of which are funded by the Major Research Equipment program of the National Science Foundation (NSF) and one of which is mostly associated with the National Aeronautics and Space Administration (NASA). In response to a request by the NSF, the National Research Council (NRC) established a committee to review the science objectives and implementation planning of the three NSF components, United States Seismic Array (USArray), the Plate Boundary Observatory (PBO), and the San Andreas Fault Observatory at Depth (SAFOD). The committee was charged with answered four specific questions: Is the scientific rationale for EarthScope sound, and are the scientific questions to be addressed of significant importance? Is there any additional component that should be added to the EarthScope initiative to ensure that it will achieve its objective of a vastly increased understanding of the structure, dynamics, and evolution of the continental crust of North America? Are the implementation and management plans for the three elements of EarthScope reviewed here appropriate to achieve their objectives? Have the appropriate partnerships required to maximize the scientific outcomes from EarthScope been identified in the planning documents? Review of EarthScope Integrated Science presents the committee's findings and recommendations. To reach its conclusions the committee reviewed extensive written material and listened to presentations by members of the EarthScope Working Group and other interested scientists. The recommendations encompass science questions, management, education and outreach, and partnerships. Overall the committee was impressed by the EarthScope initiative.

This book is a collection of comprehensive reviews on astrophysics at the highest energies. It puts together, for the first time, discussions of astrophysics from MeV to EeV energies and beyond. Observations at these energies reveal nuclear and particle physics throughout our galaxy as well as in the most extreme environments in the entire cosmos. These reports range from the recent spectacular results from the Compton Gamma Ray Observatory, including the latest information on enigmatic gamma ray bursts, to cosmic rays at the highest energies ever observed by man.

Phys. G: Nucl. Part. Phys. “The book is thus accessible to graduate students with a physics background and would be a useful addition to the libraries of institutions with an interest in astronomy and to the bookshelves of workers close to the field. Its cost is not excessive by modern standards and represents good value given the very high quality of the astrophysical material it contains.” Australian & New Zeland Physicist

Since its launch in 2013, IRIS has observed more than 10 X-class, over 100 M-class and more than 600 C-class flares at unprecedented spatial and temporal resolution. Thanks to the rich diagnostics that cover the physical conditions of the solar atmosphere from the photosphere to the hottest parts of the flaring corona, IRIS observations have provided exciting new results and constraints on flare heating models, significantly expanding our knowledge of how flares are triggered, and how the non-thermal energy is released, propagates downward from the corona, and is deposited in the low atmosphere. At the same time, the new discoveries provided by IRIS have raised new unresolved questions and new challenges for theoretical models. For instance, current hydrodynamic models still cannot fully explain many features observed by IRIS during both the impulsive and gradual phases such as the dynamics of the evaporative/condensation flows, the large line broadenings, and the puzzling complex and broad chromospheric lines. In addition, important questions remain regarding the details of the energy propagation and dissipation in flares, the importance of Alfvén waves vs electron-beam and thermal conduction heating, and the effects from large-scale reconfiguration of the magnetic field during flares.
