Travel through time with the maestros as they explore the amazing history of timekeeping! Did you know that there is more than one calendar? While the most commonly used calendar was on the year 2000, the Jewish calendar said it was the year 5760, while the Muslim calendar said 1420 and the Chinese calendar said 4698. Why do these differences exist? How did ancient civilizations keep track of time? When and how were clocks first invented? Find answers to all these questions and more in this incredible trip through history.
Historians will look back over time at the events of the fall of 2019 and the impeachment of Donald J. Trump, and will debate the merits of the charges and the circumstances that caused the whole debacle. In The Clock and the Calendar, Congressman Doug Collins will explain why the impeachment was not really about a phone call with a foreign leader or how the president conducted himself; no, it was not even about the Russia investigation that had fizzled just months before these proceedings. What happened in the halls of Congress during this time was merely a date with a destiny that was dreamed of by Democrats still feeling the sting of bitter tears in Brooklyn on the night that Donald Trump derailed the coronation of Hillary Clinton. It was on that night that the mainstream media was stunned and brought to tears, and the Washington establishment shook to their very core, that the seed was planted. We may not have won tonight, they said, but we will never let this stand. Instead of looking to win again in four years, the movement began to look for another solution. Seeds had already been sown: the way was impeachment and that was the destiny they sought.
What is time? When did we first use it? Does it always work? How do animals tell time? A fun and fascinating look at time from the first calendars and clocks to the digital watches and precise time-keeping methods of today.
This book explores how daily and seasonal rhythmicity is generated, how these rhythms are synchronised by our environment, and how they regulate the neuroendocrine systems that impact our physiology and behaviour. The constraints of surviving in a seasonal environment have shaped human evolution and migration, have shaped our societies and cultures, and continue to influence our everyday lives, health and wellbeing. Identifying the mechanisms whereby seasonal rhythmicity is generated and regulates the brain and body is not only important for understanding the natural world and relevant to animal production, it also offers many insights into the human condition. Each chapter is written by an international expert in the field of chronobiology. A historical perspective on how research into photoperiodism and rhythmicity progressed is initially provided, but the main focus of this book is on the remarkable studies in the last few decades that have unravelled the molecular and cellular machinery underpinning circadian and circannual timing. Topics covered include the role of melatonin in communicating seasonal information to the brain and pituitary gland, the neuroanatomical pathways in mammals, birds and fish by which changes in photoperiod reach the hypothalamus, the role of glial cells (tanycytes) and thyroid hormone in seasonal rhythmicity, neuroplasticity across seasons, effects of changing day length on mood, regulation of “clock“ gene expression, and the role of the suprachiasmatic nucleus. This book will appeal to all students and researchers who wish to learn about current and past research on daily and seasonal rhythmicity. This is the tenth volume in the International Neuroendocrine Federation (INF) Masterclass in Neuroendocrinology series (Volumes 1-7 published by Wiley) that aims to illustrate highest standards and encourage the use of the latest technologies in basic and clinical research and hopes to provide inspiration for further exploration into the exciting field of neuroendocrinology.
"If you lie awake worrying about the overnight transition from December 31, 1 b.c., to January 1, a.d. 1 (there is no year zero), then you will enjoy Duncan Steel's Marking Time."--American Scientist "No book could serve as a better guide to the cumulative invention that defines the imaginary threshold to the new millennium."--Booklist A Fascinating March through History and the Evolution of the Modern-Day Calendar . . . In this vivid, fast-moving narrative, you'll discover the surprising story of how our modern calendar came about and how it has changed dramatically through the years. Acclaimed author Duncan Steel explores each major step in creating the current calendar along with the many different systems for defining the number of days in a week, the length of a month, and the number of days in a year. From the definition of the lunar month by Meton of Athens in 432 b.c. to the roles played by Julius Caesar, William the Conqueror, and Isaac Newton to present-day proposals to reform our calendar, this entertaining read also presents "timely" tidbits that will take you across the full span of recorded history. Find out how and why comets have been used as clocks, why there is no year zero between 1 b.c. and a.d. 1, and why for centuries Britain and its colonies rang in the New Year on March 25th. Marking Time will leave you with a sense of awe at the haphazard nature of our calendar's development. Once you've read this eye-opening book, you'll never look at the calendar the same way again.
Three streams of history created the Western calendar - from the East beginning with the Sumerians, from the Celtic and Germanic peoples in the North, and again from the East, this time from Palestine with the rise of Christianity. The author teases out the contributions of each stream.
