1972-1997, Twenty-five years of energy and environmental history : lessons learned.

Given the events of the past 25 years concerning energy and environmental issues and our reaction to them, what lessons can we learn? First, the individual American consumer wants and expects energy to be a stable commodity with low prices and easy availability. As evidenced by the heated debate over increasing the federal gasoline tax by $.05 per gallon (which would still leave Americans paying only one-third of what Europeans pay for gasoline), increases in energy prices elicit very strong public and political opposition. As further evidence, it has been argued that the general public support of the Gulf War was due, in part, to a recognition of the need to maintain a stable source of cheap oil from the region. The American public wants to maintain the benefits of cheap and abundant energy and expects its political leaders to make it happen. A second lesson is that if constraints on the energy supply do occur (e.g., the OPEC-imposed oil embargo) ardor environmental impacts from energy use do appear to be significant (e.g., SO{sub 2} and CO{sub 2} emissions), the preference is for a technology fix rather than a behavioral change. This is evidenced by our reliance on moving low-sulfur …

Near-Death and Out-of-Body Experiences in the Blind: A Study of Apparent Eyeless Vision (open access)

Near-Death and Out-of-Body Experiences in the Blind: A Study of Apparent Eyeless Vision

Article reporting the results of an investigation into near-death and out-of-body experiences in 31 blind respondents. The study sought to address three main questions: (1) whether blind individuals have near-death experiences (NDEs) and, if so, whether they are the same as or different from those of sighted persons; (2) whether blind persons ever claim to see during NDEs and out-of-body experiences (OBEs); and (3) if such claims are made, whether they can ever be corroborated by reference to independent evidence.

Structure and dynamics of few-nucleon systems (open access)

Structure and dynamics of few-nucleon systems

Few-nucleon physics is a field rich with high-quality experimental data and possibilities for accurate calculations of strongly-correlated quantum systems. In this article the authors discuss the traditional model of the nucleus as a system of interacting nucleons and outline many recent experimental results and theoretical developments in the field of few-nucleon physics. They present discussions of nuclear structure and spectra, clustering and correlations, elastic and inelastic electromagnetic form factors, low energy electroweak reactions, and nuclear scattering and response in the quasi-elastic regime. Through a review of the rich experimental data and a variety of theoretical developments, a coherent description of the nuclear strong and electroweak interaction properties emerges. In this article, they attempt to provide some insight into the practice and possibilities of in few-nucleon physics today.
