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.

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.

It was the place where blues, pop, and country merged into rock and roll--and the sounds that emerged from the tiny storefront at 706 Union Avenue in Memphis are still reverberating around the world nearly fifty years after they were made. On Sam Phillips's bright yellow Sun Records label spun a mind-bendingly eclectic body of music by Carl Perkins, Jerry Lee Lewis, Roy Orbison, Charlie Rich, Junior Parker, Johnny Cash, and many others. And one day, a gawky nobody named Elvis Presley walked in.

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.

In Memphis, Tennessee, in the 1950s, there was hard-edged blues playing on Beale Street, and hillbilly boogie on the outskirts of town. But at Sam Phillips’ Sun Records studio on Union Avenue, there was something different going on – a whole lotta shakin’, rockin’, and rollin’. This is where rock ’n’ roll was born. Sun Records: the company that launched Elvis Presley, Jerry Lee Lewis, Johnny Cash, Roy Orbison, and Carl Perkins. The label that brought the world, “Blue Suede Shoes,” “Whole Lotta Shakin’ Goin’ On,” “Breathless,” “I Walk the Line,” “Mystery Train,” “Good Rockin’ Tonight.” The Birth of Rock ’n’ Roll: 70 Years of Sun Records is the official history of this legendary label, and looks at its story in a unique way: through the lens of 70 of its most iconic recordings. From the early days with primal blues artists like Howlin’ Wolf and B.B. King to long nights in the studio with Elvis and Jerry Lee Lewis, you will see how the label was shaped and how it redefined American music. Accompanying the recordings is the label’s origin story and a look at the mission of the label today, as well as “Sun Spot” sidebars—a fascinating dive into subjects such as how the iconic logo was created, the legendary Million Dollar Quartet sessions, and how the song “Harper Valley, PTA” funded the purchase of the label. Written by two of the most acclaimed music writers of our time, Peter Guralnick and Colin Escott, and featuring hundreds of rare images from the Sun archives as well as a foreword by music legend Jerry Lee Lewis, this is a one-of-a-kind book for anyone who wants to know where it all started.

" ... 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.

This book is intended for geophysicists, astronomers (especially those with an interest in history), historians and orientalists. The culmination of many years of research, it discusses, in depth, ancient and medieval eclipse observations and their importance in studying Earth's past rotation. This was the first major book on this subject to appear in the last twenty years. The author has specialised in the interpretation of early astronomical records and their application to problems in modern astronomy for many years. The book contains an in-depth discussion of numerous eclipse records from Babylon, China, Europe and the Arab lands. Translations of almost every record studied are given. It is shown that although tides play a dominant long-term role in producing variations in Earth's rate of rotation - causing a gradual increase in the length of the day - there are significant, and variable non-tidal changes in opposition to the main trend.

An interdisciplinary approach to solar physics, as eighty-nine contributors trace the evolution of the Sun and provide a review of our current understanding of both its structure and its role in the origin and evolution of the solar system.

Solar and geomagnetic variability are of considerable interest for scientists of many different persuasions and indeed one has the distinct impression that for the sun at least, there is direct relevance for mankind in general as the interrelation between solar and terrestrial phenomena is starting to be appreciated. From the vast time scale of interest in the variability field, attention was confined to the last 10,000 years in a NATO Advanced Research Workshop held from April 6 - 10, 1987 in Durham, England, and the present publication comprises the lectures given there. Such a Workshop was very timely in view of the impressive new data available from 14C analysis in dated tree rings and lOBe in polar ice cores, from natural palaeomagnetic records in lacustrine sediments and from archaeomagnetic material. Also to be mentioned are new studies of historical accounts of naked-eye sunspots and aurorae. All the data have contributed to improvements in under standing the relative variations of solar properties, the geomagnetic field and climate and it is hoped that this volume will convey the flavour of these advances in knowledge. A feature of the Workshop was the lively discussions which followed so many of the papers. There were several instances of healthy disagreement and this is reflected in the opposing views presented inanumber of the papers published here.
