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)

Book Description
The most thrilling, genre-busting, unlikely science book you’ll ever read, from the world-renowned, multi-award-winning, superstar physicist Lisa Randal. 66 million years ago, a ten-mile-wide object from outer space hurtled into the Earth at incredible speed. The impact annihilated the dinosaurs, along with three-quarters of the other species on the planet. But what if this catastrophe was the sign of something greater: an opening vista onto the interconnectedness of the universe itself? This is the story of the astounding forces that underpin our existence; a horizon-expanding tour of the cosmos that unifies what we know about the universe with new thinking. From the far-flung reaches of space, the makeup of the universe and our solar system's place within it, to the mysterious and elusive stuff of dark matter and how it affects life here on Earth. ‘A fascinating, and surprisingly simple, theory...and a tantalising premise’ The Times ‘Extremely engaging’ BBC Focus

Book Description
A New York Times Notable Book: A particle physicist’s “engaging and remarkably clear” look at the dimensions that may exist beyond the ones we know (The New York Times Book Review). The universe has many secrets. It may hide additional dimensions of space other than the familiar 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 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. “Randall brings much of the excitement of her field to life as she describes her quest to understand the structure of the universe.” —Publishers Weekly “A great read . . . I highly recommend it.” —Ira Flatow, host of NPR’s Science Friday “Randall, a professor of physics at Harvard, offers a tour of current questions in particle physics, string theory, and cosmology, paying particular attention to the thesis that more physical dimensions exist than are usually acknowledged . . . She’s honest about the limits of the known, and almost revels in the uncertainties that underlie her work—including the possibility that some day it may all be proved wrong.” —The New Yorker

Book Description
“[A] highly readable, accessible look at particle physics today and...a passionate defense and celebration of the scientific worldview” (Discovery News). One of Time magazine’s 100 most influential people in the world and the bestselling author of Warped Passages, Lisa Randall is an expert in both particle physics (the study of the smallest objects we know of) and cosmology (the study of the largest). In this book, Randall takes us on an amazing tour through the latest developments in physics—including a new preface explaining the thrilling discovery of the Higgs boson—and the theoretical concepts underlying this work. Knocking on Heaven’s Door also explores the role of risk, creativity, uncertainty, beauty, and truth in scientific thinking. Through provocative conversations with leading figures in other fields, including chef David Chang, forecaster Nate Silver, and screenwriter Scott Derrickson, and through reflections on her own work, Randall makes an impassioned argument in defense of science. Praise for Knocking on Heaven’s Door “Randall is . . . one of the more original theorists at work in the profession today. . . . She gives a fine analysis of the affinity between scientific and artistic beauty, comparing the broken symmetries of a Richard Serra sculpture to those at the core of the Standard Model.” —New York Times Book Review, 100 Notable Books of 2011 “Written with dry wit and ice-cool clarity. . . . Knocking on Heaven’s Door is a book that anyone at all interested in science must read. This is surely the science book of the year.” —Sunday Times (London) “Valuable and engaging. . . . Randall’s generous cornucopia of ideas, her engaging style, and above all her deep excitement about physics make this a book that deserves a wide readership.” —American Scientist

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
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.

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.

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.

Book Description
On July 4, 2012, physicists at the Large Hadron Collider in Geneva madehistory when they discovered an entirely new type of subatomic particle that many scientists believe is the Higgs boson. For forty years, physicists searched for this capstone to the Standard Model of particle physics—the theory that describes both the most elementary components that are known in matter and the forces through which they interact. This particle points to the Higgs field, which provides the key to understanding why elementary particles have mass. In Higgs Discovery, Lisa Randall explains the science behind this monumental discovery, its exhilarating implications, and the power of empty space.
