In 1998, my colleague, Forrest Mims, and I began a project to develop inexpensive handheld atmosphere monitoring instruments for the GLOBE Program, an international environmental science and education program that began its operations on Earth Day, 1995. GLOBE’s goal was to involve students, teachers, and scientists around the world in authentic partn- ships in which scientists would develop instrumentation and experimental protocols suitable for student use. In return, data collected by students and their teachers would be used by scientists in their research. This kind of collaboration represented a grand vision for science education which had never before been attempted on such a scale, and we embraced this vision with great enthusiasm. Between 1998 and 2006, Forrest Mims and I collaborated on the development of several instruments based on Mims’ original concept of using light emitting diodes as spectrally selective detectors of sunlight, which was first published in the peer-reviewed literature in 1992. These instruments have evolved into a set of tools and procedures for monitoring the transmission of sunlight through the atmosphere, and they can be used to learn a great deal about the composition of the atmosphere and the dynamics of the Earth/atmosphere/sun system. If measurements with these instruments are made properly, they have significant scientific value, as well.

" ... Concise explanations and descriptions - easily read and readily understood - of what we know of the chain of events and processes that connect the Sun to the Earth, with special emphasis on space weather and Sun-Climate."--Dear Reader.

Explores the cycles of the sun and moon and discusses early calendars and the work of ancient astronomers and mathematicians.

Tess Ward has compiled an original and inspiring selection of prayers. They reach beyond Christian and Celtic Pagan traditions, interweaving their calendars into a single pattern of prayer for every morning and night of the year. An important, hopeful and refreshing way forward. Dr. Gordon Lynch, Dept of Theology and Religion, Birmingham University, author of The New Spirituality.

Christ’s Body, Human Flesh If we’re honest, no one really cares about theology unless it reveals a gut-level view of God’s presence. According to pastor and ministry leader Hugh Halter, only the incarnational power of Jesus satisfies what we truly crave, and once we taste it, we’re never the same. God understands how hard it is to be human, and the incarnation—God with us—enables us to be fully alive. With refreshing, raw candor, Flesh reveals the faith we all long to experience—one based on the power of Christ in the daily grind of work, home, school, and life. For anyone burned out, disenchanted, or seeking a fresh honest-to-God encounter, Flesh will invigorate your faith.

Shortlisted for the 2022 ESSE Book Awards How has humanity sought to harness the power of the Sun, and what roles have literature, art and other cultural forms played in imagining, mythologizing and reflecting the possibilities of solar energy? What stories have been told about solar technologies, and how have these narratives shaped developments in science and culture? What can solar power's history tell us about its future, within a world adapting to climate crisis? Identifying the history of capturing solar radiance as a focal point between science and the imagination, Imagining Solar Energy argues that the literary, artistic and mythical resonances of solar power – from the Renaissance to the present day – have not only been inspired by, but have also cultivated and sustained its scientific and technological development. Ranging from Archimedes to Isaac Asimov, John Dee to Humphry Davy, Aphra Behn to J. G. Ballard, the book argues that solar energy translates into many different kinds of power (physical, political, intellectual and cultural), and establishes for the first time the importance of solar energy to many literary and scientific endeavours.
