The principal goals of the study were to articulate the scientific rationale and objectives of the field and then to take a long-term strategic view of U.S. nuclear science in the global context for setting future directions for the field. Nuclear Physics: Exploring the Heart of Matter provides a long-term assessment of an outlook for nuclear physics. The first phase of the report articulates the scientific rationale and objectives of the field, while the second phase provides a global context for the field and its long-term priorities and proposes a framework for progress through 2020 and beyond. In the second phase of the study, also developing a framework for progress through 2020 and beyond, the committee carefully considered the balance between universities and government facilities in terms of research and workforce development and the role of international collaborations in leveraging future investments. Nuclear physics today is a diverse field, encompassing research that spans dimensions from a tiny fraction of the volume of the individual particles (neutrons and protons) in the atomic nucleus to the enormous scales of astrophysical objects in the cosmos. Nuclear Physics: Exploring the Heart of Matter explains the research objectives, which include the desire not only to better understand the nature of matter interacting at the nuclear level, but also to describe the state of the universe that existed at the big bang. This report explains how the universe can now be studied in the most advanced colliding-beam accelerators, where strong forces are the dominant interactions, as well as the nature of neutrinos.

A novel, integrated approach to understanding long-term human history, viewing it as the long-term evolution of human information-processing. This title is also available as Open Access.

Dramatic progress has been made in all branches of physics since the National Research Council's 1986 decadal survey of the field. The Physics in a New Era series explores these advances and looks ahead to future goals. The series includes assessments of the major subfields and reports on several smaller subfields, and preparation has begun on an overview volume on the unity of physics, its relationships to other fields, and its contributions to national needs. Nuclear Physics is the latest volume of the series. The book describes current activity in understanding nuclear structure and symmetries, the behavior of matter at extreme densities, the role of nuclear physics in astrophysics and cosmology, and the instrumentation and facilities used by the field. It makes recommendations on the resources needed for experimental and theoretical advances in the coming decade.

Cyberbullying is the intentional and repeated act of causing harm to others through the use of computers, mobile phones, and other electronic devices. The authors look at the potential consequences of this deliberate behaviour and present strategies for effective identification, prevention, and response. They also include illustrations of what cyberbullying looks like, tips for identifying cyberbullies or targets and strategies for responsible social networking. This resource will assist in confronting technology-based aggression and ensure the safe and responsible use of computers and the internet.

Originally published in 1982, this collection of essays provides an integrated overview of the application of nuclear science to astronomy. The book discusses, among other topics, the abundances of the nuclear and chemical species on the Earth and the Moon, in meteorites, in the stars, and in interstellar space. The hypothesis that these species are produced by nuclear reactions is then explored and related to laboratory measurements. Other subjects include the dynamics of supernovae and interdisciplinary relationships between elementary particle physics and cosmology. The essays are dedicated to Professor William A. Fowler and pay tribute to his vast influence on the field.
