Book Description
The Sun is nowadays observed using di?erent techniques that provide an almost instantaneous 3-D map of its structure. Of particular interest is the studyofthevariabilityinthesolaroutputproducedbythedissipationofm- netic energy on di?erent spatial and temporal scales – the so-called magnetic activity. The 11-year cycle is the main feature describing this phenomenon. Apart from its intrinsic scienti?c interest, this topic is worth studying because of the interaction of such processes with the terrestrial environment. A ?eet of space and ground-based observatories are currently monitoring the behaviour of our star on a daily basis. However, solar activity varies not only on this decadal time-scale, as has been attested mainly through two methods: (a) records of the number of sunspots observed on the solar surface from 1610, and (b) the records of 14 10 cosmogenic isotopes, such as Cand Be, measured in tree-rings and i- cores, respectively. The study of the long-term behaviour of solar activity may be comp- mented by the study of historical accounts describing phenomena directly or indirectly related to solar activity. Numerous scienti?c and non-scienti?c d- uments have reported these events and we can make use of them as a proxy of solar activity in past times.

Book Description
Comprehensive and engaging, this colourful study covers the whole sweep of ritual history from the earliest written records to the present day. From May Day revels and Midsummer fires, to Harvest Home and Hallowe'en, to the twelve days of Christmas, Ronald Hutton takes us on a fascinating journey through the ritual year in Britain. He challenges many common assumptions about the customs of the past, and debunks many myths surrounding festivals of the present, to illuminate the history of the calendar year we live by today.

Book Description
What do Emily Dickinson, slave revolts, Babylonian Kings, and Monticello all have in common? A solar eclipse. Whether it was deciding on the location of a grand home (or castle), inspiring poetry, timing battles and revolts, or planning expeditions, eclipses have inspired fear and fascination. Solar eclipses allowed Ptolemy to determine the length of the Mediterranean and helped Einstein establish his General Theory of Relativity. Preliterate societies recorded eclipses on turtle shells found in "The Wastes of Yin" and on the Mayan "Dresden Codex." Eclipses were later instrumental in the creation of longitude and allowed Hubble to understand the expansion of the Universe (and disprove another theory of Einstein's in the process). John Dvorak, the acclaimed author of Earthquake Storms and The Last Volcano, examines this amazing phenomena and reveals the humanism behind the science. With insightful detail and vividly accessible prose, he provides explanations as to how and why eclipses occur—as well as insight into the eclipse of 2017, which was visible across North America.

Book Description
William Gascoigne (c.1612-44) was the inventor of the telescopic sight and micrometer (instruments crucial to the advance of astronomy). His name is now known to historians of science around the world. For some considerable time after his tragic death at the age of 32 in the English Civil War, however, it seemed as if his achievements would be consigned to oblivion. Most of his papers were lost and even the few that survived have largely disappeared. This is the story of how his work was rescued. Into this story is woven an account of the state of astronomy and optics during Gascoigne’s lifetime, so that the reader can appreciate the significance of his discoveries.

Book Description
Creation myths around the world reveal an intricate network of recurrent motifs. Many of these are counterintuitive and not widely known, describing a time when the sky was low, the stars did not yet shine, multiple suns appeared, the moon was brighter than the sun, no land existed, deities and mortals maintained frequent contact, a 'world axis' in the form of a tree, ladder or giant man connected the earth with the sky, a devastating flood or fire ended the old order, and so forth. The present work, in multiple volumes, aims to find an origin for this cross-culturally and internally consistent body of traditions in a series of extraordinary natural events relating especially to the earth's transition from the last glacial period to the Holocene. This first volume sets the stage for the interdisciplinary hypothesis. Essential lines of research receive a historical introduction: comparative mythology, catastrophism and the study of the mythical world axis in relation to the earth's rotation. Various astronomical and meteorological interpretations that are not strictly catastrophist are explored for several types of myths about the sun, the moon and the world axis, but leave many of the most intriguing traditions unexplained. It is argued that a structural core of the worldwide mythology of 'creation and destruction', in which the cosmic axis takes pride of place, points to a specific period of dramatic natural circumstances in real prehistoric time. A new synopsis is provided of this universal mythological substrate. It emerges that the mythical world axis cannot have been based on a single object seen or imagined at one of the poles, as has usually been supposed. This surprising conclusion paves the way for the innovative geomagnetic theory proposed in volume 2.
