    Lyman alpha line shapes from electron impact H2 dissociative processes in the Jovian auroral zone

    Over the past two years several Lyman alpha line profile spectra of Jupiter were obtained using the International Ultraviolet Explorer (IUE) telescope. Several different regions of the planet were observed including the auroral zone, the low and mid latitudes, and the equatorial region which includes the Lyman alpha bulge region. These results have presented a very interesting picture of atomic hydrogen on Jupiter with explanations that range from ion outflow in the auroral zone to large thermospheric winds at low and mid latitudes. New data are needed to address the outstanding questions. Almost certainly, high resolution spectra from the Hubble Space Telescope will play a role in new observations. Better data also require better models, and better models require new laboratory data as inputs. The purpose of this program is two-fold: (1) to introduce a method by which new laboratory electron impact measurements of H2 dissociation can be used to calculate both the slow and fast H(S-2) and H(P-2) fragments in an H2 atmosphere; and (2) to determine the predicted Lyman alpha line shape that would result from electron impact production of these dissociative fragments in the Jovian auroral zone

    A Call From the Panopticon to the Judicial Chamber “Expect Privacy!â€

    Privacy is necessary in order for one to develop physically, mentally and affectively. Autonomy and self definitionhave been recognized by the United States Supreme Court as being values of privacy. In our technologicallyadvanced, and fear driven society, however, our right to privacy has been severely eroded. Due to encroachmentby government and business we have a diminished expectation of privacy. This article examines the detriments toself and society which result from a reduced sphere of privacy, as well as offering a modest suggestion for amethod to reintroduce an improved conception of privacy into citizens’ lives
