Book Synopsis When Humans Nearly Vanished by : Donald R. Prothero
Download or read book When Humans Nearly Vanished written by Donald R. Prothero and published by Smithsonian Institution. This book was released on 2018-10-16 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fascinating true story of the explosion of the Mount Toba supervolcano--the Earth's largest eruption in the past 28 million years--and its lasting impact on Earth and human evolution Some 73,000 years ago, the huge dome of Mount Toba, in today's Sumatra, Indonesia, began to rumble. A deep vibration shook the entire island. Jets of steam and ash emanated from the summit, followed by an explosion louder than any sound heard by Homo sapiens since our species evolved on Earth. The eruption of the Toba supervolcano released the energy of a million tons of explosives; seven hundred cubic miles of magma spewed outward in an explosion forty times larger than the largest hydrogen bomb and more than a thousand times as powerful as the Krakatau eruption in 1883. So much ash and debris was injected into the stratosphere that it partially blocked the sun's radiation and caused global temperatures to drop by five to nine degrees. It took a full decade for Earth to recover to its pre-eruption temperatures. When Humans Nearly Vanished presents the controversial argument that the Toba catastrophe nearly wiped out the human race, leaving only about a thousand to ten thousand breeding pairs of humans worldwide. Human genes today show evidence of a "genetic bottleneck," an effect seen when a population of organisms becomes so small that their genetic diversity is greatly reduced. This group of survivors could be the ancestors of all humans alive today. Donald R. Prothero explores the geological and biological evidence supporting the Toba bottleneck theory; reveals how the explosion itself was discovered; and offers insight into how the world changed afterward and what might happen if such an eruption occurred today. Prothero's riveting account of this calamitous supervolcanic explosion is not to be missed.

Book Synopsis Apollo's Legacy by : Roger D. Launius
Download or read book Apollo's Legacy written by Roger D. Launius and published by Smithsonian Institution. This book was released on 2019-05-14 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: An all-encompassing look at the history and enduring impact of the Apollo space program In Apollo's Legacy, space historian Roger D. Launius explores the many-faceted stories told about the meaning of the Apollo program and how it forever altered American society. The Apollo missions marked the first time human beings left Earth's orbit and visited another world, and thus they loom large in our collective memory. Many have detailed the exciting events of the Apollo program, but Launius offers unique insight into its legacy as seen through multiple perspectives. He surveys a wide range of viewpoints and narratives, both positive and negative, surrounding the program. These include the argument that Apollo epitomizes American technological--and political--progress; technological and scientific advances garnered from the program; critiques from both sides of the political spectrum about the program's expenses; and even conspiracy theories and denials of the program's very existence. Throughout the book, Launius weaves in stories from important moments in Apollo's history to draw readers into his analysis. Apollo's Legacy is a must-read for space buffs interested in new angles on a beloved cultural moment and those seeking a historic perspective on the Apollo program.
Download or read book The Last Elephants written by Colin Bell and published by Penguin Random House South Africa. This book was released on 2019-03-01 with total page 563 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Africa-wide Great Elephant Census of 2016 produced shocking findings: a decimated elephant population whose numbers were continuing to plummet. Elephants are killed, on average, every 15–20 minutes – a situation that will see the final demise of these intelligent, extraordinary animals in less than three decades. They are a species in crisis. This magnificent book offers chapters written by the most prominent people in the realm of conservation and wildlife, among them researchers, conservationists, film makers, criminologists, TV personalities and journalists. Photographs have been selected from among Africa’s best wildlife photographers, and the Foreword is provided by Prince William. It is hoped this book will create awareness of the devastating loss of elephant lives in Africa and stem the tide of poaching and hunting; that it will inspire the delegates to CITES to make informed decisions to ensure that all loopholes in the ivory trade are closed; and that countries receiving and using ivory (both legal and poached) – primarily China, Vietnam, Laos and Japan – ban and strenuously police its trade and use within their borders, actively pursuing and arresting syndicate leaders driving the cruel poaching tsunami. This book is also a tribute to the many people who work for the welfare of elephants, particularly those who risk their lives for wildlife each day, often for little or no pay – in particular the field rangers and the anti-poaching teams; and to the many communities around Africa that have elected to work with elephants and not against them. The Last Elephants – is the title prophetic? We hope not, but the signs are worrying.

Book Synopsis Flags of the Night Sky by : André G. Bordeleau
Download or read book Flags of the Night Sky written by André G. Bordeleau and published by Springer Science & Business Media. This book was released on 2013-10-22 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many national flags display astronomical features – Sun, Moon, stars – but are they really based on existing astronomical objects? The United States flag sports 50 stars, one for each state, however none of them are linked to real stars. Further, the lunar crescent is often shaped like the Sun being eclipsed by the Moon. At times, stars are seen right next to the crescent, where the darkened disc of the moon should be! This book will present true astronomical objects and patterns highlighted on national flags and link informative capsules about these objects to the political reasons why they were chosen to adorn such an important symbol.
