Book Description
“Takes readers on illuminating scientific adventure, beginning sixty-six million years ago, that connects dinosaurs, comets, DNA, and the future of the planet.” —Huffington Post In this brilliant exploration of our cosmic environment, the renowned particle physicist and New York Times–bestselling author of Warped Passages and Knocking on Heaven’s Door uses her research into dark matter to illuminate the startling connections between the furthest reaches of space and life here on Earth. Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a devastating cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? In Dark Matter and the Dinosaurs, Lisa Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter embedded in the Milky Way. In a sense, it might have been dark matter that killed the dinosaurs. Working through the background and consequences of this proposal, Randall shares with us the latest findings—established and speculative—regarding the nature and role of dark matter and the origin of the Universe, our galaxy, our Solar System, and life, along with the process by which scientists explore new concepts. In Dark Matter and the Dinosaurs, Randall tells a breathtaking story that weaves together the cosmos’ history and our own, illuminating the deep relationships that are critical to our world and the astonishing beauty inherent in the most familiar things. “Randall has woven a beautiful account of how life on Earth is intimately connected to the cosmos.” —The Daily Telegraph (UK)

Warped Passages PDF Author: Lisa Randall
Publisher: Harper Collins
ISBN: 0061981230
Category : Science
Languages : en
Pages : 782

Book Description
The universe has many secrets. It may hide additional dimensions of space other than the familier three we recognize. There might even be another universe adjacent to ours, invisible and unattainable . . . for now. Warped Passages is a brilliantly readable and altogether exhilarating journey that tracks the arc of discovery from early twentieth-century physics to the razor's edge of modern scientific theory. One of the world's leading theoretical physicists, Lisa Randall provides astonishing scientific possibilities that, until recently, were restricted to the realm of science fiction. Unraveling the twisted threads of the most current debates on relativity, quantum mechanics, and gravity, she explores some of the most fundamental questions posed by Nature—taking us into the warped, hidden dimensions underpinning the universe we live in, demystifying the science of the myriad worlds that may exist just beyond our own.

Why Dinosaurs Matter

Why Dinosaurs Matter PDF Author: Kenneth Lacovara
Publisher: Simon and Schuster
ISBN: 1501120107
Category : Nature
Languages : en
Pages : 192

Book Description
What can long-dead dinosaurs teach us about our future? Plenty, according to paleontologist Kenneth Lacovara, who has discovered some of the largest creatures to ever walk the Earth. By tapping into the ubiquitous wonder that dinosaurs inspire, Lacovara weaves together the stories of our geological awakening, of humanity’s epic struggle to understand the nature of deep time, the meaning of fossils, and our own place on the vast and bountiful tree of life. Go on a journey––back to when dinosaurs ruled the Earth––to discover how dinosaurs achieved feats unparalleled by any other group of animals. Learn the secrets of how paleontologists find fossils, and explore quirky, but profound questions, such as: Is a penguin a dinosaur? And, how are the tiny arms of T. rex the key to its power and ferocity? In this revealing book, Lacovara offers the latest ideas about the shocking and calamitous death of the dinosaurs and ties their vulnerabilities to our own. Why Dinosaurs Matter is compelling and engaging—a great reminder that our place on this planet is both precarious and potentially fleeting. “As we move into an uncertain environmental future, it has never been more important to understand the past.”

Book Description
'Clear and compact ... It's hard to fault as a brief, easily digestible introduction to some of the biggest questions in the Universe' Giles Sparrow, BBC Four's The Sky at Night , Best astronomy and space books of 2019: 5/5 All the matter and light we can see in the universe makes up a trivial 5 per cent of everything. The rest is hidden. This could be the biggest puzzle that science has ever faced. Since the 1970s, astronomers have been aware that galaxies have far too little matter in them to account for the way they spin around: they should fly apart, but something concealed holds them together. That 'something' is dark matter - invisible material in five times the quantity of the familiar stuff of stars and planets. By the 1990s we also knew that the expansion of the universe was accelerating. Something, named dark energy, is pushing it to expand faster and faster. Across the universe, this requires enough energy that the equivalent mass would be nearly fourteen times greater than all the visible material in existence. Brian Clegg explains this major conundrum in modern science and looks at how scientists are beginning to find solutions to it.

Defending Planet Earth

Defending Planet Earth PDF Author: National Research Council
Publisher: National Academies Press
ISBN: 0309149681
Category : Science
Languages : en
Pages : 152

Book Description
The United States spends approximately $4 million each year searching for near-Earth objects (NEOs). The objective is to detect those that may collide with Earth. The majority of this funding supports the operation of several observatories that scan the sky searching for NEOs. This, however, is insufficient in detecting the majority of NEOs that may present a tangible threat to humanity. A significantly smaller amount of funding supports ways to protect the Earth from such a potential collision or "mitigation." In 2005, a Congressional mandate called for NASA to detect 90 percent of NEOs with diameters of 140 meters of greater by 2020. Defending Planet Earth: Near-Earth Object Surveys and Hazard Mitigation Strategies identifies the need for detection of objects as small as 30 to 50 meters as these can be highly destructive. The book explores four main types of mitigation including civil defense, "slow push" or "pull" methods, kinetic impactors and nuclear explosions. It also asserts that responding effectively to hazards posed by NEOs requires national and international cooperation. Defending Planet Earth: Near-Earth Object Surveys and Hazard Mitigation Strategies is a useful guide for scientists, astronomers, policy makers and engineers.

Mapping the Heavens

Mapping the Heavens PDF Author: Priyamvada Natarajan
Publisher: Yale University Press
ISBN: 0300221126
Category : Science
Languages : en
Pages : 337

Book Description
A theoretical astrophysicist explores the ideas that transformed our knowledge of the universe over the past century. The cosmos, once understood as a stagnant place, filled with the ordinary, is now a universe that is expanding at an accelerating pace, propelled by dark energy and structured by dark matter. Priyamvada Natarajan, our guide to these ideas, is someone at the forefront of the research—an astrophysicist who literally creates maps of invisible matter in the universe. She not only explains for a wide audience the science behind these essential ideas but also provides an understanding of how radical scientific theories gain acceptance. The formation and growth of black holes, dark matter halos, the accelerating expansion of the universe, the echo of the big bang, the discovery of exoplanets, and the possibility of other universes—these are some of the puzzling cosmological topics of the early twenty-first century. Natarajan discusses why the acceptance of new ideas about the universe and our place in it has never been linear and always contested even within the scientific community. And she affirms that, shifting and incomplete as science always must be, it offers the best path we have toward making sense of our wondrous, mysterious universe. “Part history, part science, all illuminating. If you want to understand the greatest ideas that shaped our current cosmic cartography, read this book.”—Adam G. Riess, Nobel Laureate in Physics, 2011 “A highly readable, insider’s view of recent discoveries in astronomy with unusual attention to the instruments used and the human drama of the scientists.”—Alan Lightman, author of The Accidental Universe and Einstein's Dream

The Lost Dinosaurs of Egypt

The Lost Dinosaurs of Egypt PDF Author: William Nothdurft
Publisher: Random House
ISBN: 1588361179
Category : Science
Languages : en
Pages : 209

Book Description
The date is January 11, 1911. A young German paleontologist, accompanied only by a guide, a cook, four camels, and a couple of camel drivers, reaches the lip of the vast Bahariya Depression after a long trek across the bleak plateau of the western desert of Egypt. The scientist, Ernst Freiherr Stromer von Reichenbach, hopes to find fossil evidence of early mammals. In this, he will be disappointed, for the rocks here will prove to be much older than he thinks. They are nearly a hundred million years old. Stromer is about to learn that he has walked into the age of the dinosaurs. At the bottom of the Bahariya Depression, Stromer will find the remains of four immense and entirely new dinosaurs, along with dozens of other unique specimens. But there will be reversals—shipments delayed for years by war, fossils shattered in transit, stunning personal and professional setbacks. Then, in a single cataclysmic night, all of his work will be destroyed and Ernst Stromer will slip into history and be forgotten. The date is January 11, 2000—eighty-nine years to the day after Stromer descended into Bahariya. Another young paleontologist, Ameri-can graduate student Josh Smith, has brought a team of fellow scientists to Egypt to find Stromer’s dinosaur graveyard and resurrect the German pioneer’s legacy. After weeks of digging, often under appalling conditions, they fail utterly at rediscovering any of Stromer’s dinosaur species. Then, just when they are about to declare defeat, Smith’s team discovers a dinosaur of such staggering immensity that it will stun the world of paleontology and make headlines around the globe. Masterfully weaving together history, science, and human drama, The Lost Dinosaurs of Egypt is the gripping account of not one but two of the twentieth century’s great expeditions of discovery.
