This book is a supplement to What If? and intended to enhance the experience of reading the original book. We recommend purchasing the full version of What If? on Amazon in addition to this book. Introduction What If? Serious Scientific Answers to Absurd Hypothetical Questions presents a wide variety of questions covering a range of dubious potentialities and the results which would ensue should they become reality. The questions are collected from author Randall Munroe’s website, where they are sent in by readers of his blog. Some of the questions are conceptual, for example how much force would be required for Yoda to lift an X-fighter, others are in a more serious vein. All of the answers however are based on research and the application of scientific principles by the author, himself trained in physics and a former roboticist for NASA.

    With the Big Bang, it went from a state of unimaginable density to an all-encompassing cosmic fireball to a simmering fluid of matter and energy, laying down the seeds for everything from dark matter to black holes to one rocky planet orbiting a star near the edge of a spiral galaxy that happened to develop life. But what happens at the end of the story? In billions of years, humanity could still exist in some unrecognizable form, venturing out to distant space, finding new homes and building new civilizations. But the death of the universe is final. What might such a cataclysm look like? And what does it mean for us? Dr. Katie Mack has been contemplating these questions since she was eighteen, when her astronomy professor first informed her the universe could end at any moment, setting her on the path toward theoretical astrophysics. Now, with lively wit and humor, she unpacks them in The End of Everything, taking us on a mind-bending tour through each of the cosmos’ possible finales: the Big Crunch; the Heat Death; Vacuum Decay; the Big Rip; and the Bounce. In the tradition of Neil DeGrasse’s bestseller Astrophysics for People in a Hurry, Mack guides us through major concepts in quantum mechanics, cosmology, string theory, and much more, in a wildly fun, surprisingly upbeat ride to the farthest reaches of everything we know.

    Czerski provides the tools to alter the way we see everything around us by linking ordinary objects and occurrences, like popcorn popping, coffee stains, and fridge magnets, to big ideas like climate change, the energy crisis, or innovative medical testing. She provides answers to vexing questions: How do ducks keep their feet warm when walking on ice? Why does it take so long for ketchup to come out of a bottle? Why does milk, when added to tea, look like billowing storm clouds? In an engaging voice at once warm and witty, Czerski shares her stunning breadth of knowledge to lift the veil of familiarity from the ordinary.

    From early concepts of whether the world was a disk floating in water (Thales) or pear-shaped (Columbus), Davis explains earthquakes, rain forests, Atlantis and whether there are canaries on the Canary Islands. In short, he covers the scientific, physical, and political history of the Earth and does his level best to raise our collective geographic IQ while entertaining us.

    It is 1845, and Hannah Gardner Price has lived all twenty-four years of her life according to the principles of the Nantucket Quaker community in which she was raised, where simplicity and restraint are valued above all, and a woman’s path is expected to lead to marriage and motherhood. But up on the rooftop each night, Hannah pursues a very different—and elusive—goal: discovering a comet and thereby winning a gold medal awarded by the King of Denmark, something unheard of for a woman. And then she meets Isaac Martin, a young, dark-skinned whaler from the Azores who, like herself, has ambitions beyond his expected station in life. Drawn to his intellectual curiosity and honest manner, Hannah agrees to take Isaac on as a student. but when their shared interest in the stars develops into something deeper, Hannah’s standing in the community begins to unravel, challenging her most fundamental beliefs about work and love, and ultimately changing the course of her life forever. Inspired by the work of Maria Mitchell, the first professional female astronomer in America, The Movement of Stars is a richly drawn portrait of desire and ambition in the face of adversity.

    We have long been told to breakfast like kings and dine like paupers. In the wake of his own type 2 diabetes diagnosis, Professor Terence Kealey was given the same advice. He soon noticed that his glucose levels were unusually high after eating in the morning, but if he fasted until lunchtime they fell. Professor Kealey began to question how much evidence there was to support the advice he’d been given, and whether there might be an advantage to not eating breakfast after all.Breakfast is a Dangerous Meal asks:What is the reliable scientific and medical evidence for eating breakfast?Who should consider intermittent fasting by removing breakfast from their daily routine?From weight loss to reduced blood pressure, what are the potential benefits of missing breakfast?

    This is just as well, according to Mark Lynas in Nuclear 2.0, because nuclear energy is essential to avoid catastrophic global warming. Using the latest world energy statistics Lynas shows that with wind and solar still at only about 1 percent of global primary energy, asking renewables to deliver all the world’s power is “dangerously delusional”. Moreover, there is no possibility of using less energy, he reminds us, when the developing world is fast extricating itself from poverty and adding the equivalent of a new Brazil to global electricity consumption each year. The anti-nuclear movement of the 1970s and 80s succeeded only in making the world more dependent on fossil fuels, he shows: its history is “not lit by sunshine, but shrouded in coal smoke”. Instead of making the same mistake again, all those who want to see a low-carbon future need to join forces, he insists, concluding the book with an ambitious proposal for an Apollo Program-style combined investment in wind, solar and nuclear power. Mark Lynas is an environmental writer and campaigner. His previous books have drawn attention to the perils of global warming, and he was Climate Advisor to the President of the Maldives from 2009-2011. He is a Visiting Research Associate at Oxford University’s School of Geography and the Environment, and a member of the World Economic Forum’s Global Agenda Council on Emerging Technologies. He recently featured in the movie documentary Pandora’s Promise, which inspired the writing of this book.

    Mark Plaster takes readers beyond the ambulance bay doors into the stranger-than-fiction world of the Emergency Department.

    As a young man, he climbed the peaks of this singular range with basic climbing gear friends. Later in life, he led treks in India, Pakistan, Nepal, China, Tibet, and Peru, but he always returned to the mountains of his youth. He continues to climb the Tetons as a guide for Exum Mountain, Guides, the oldest and most prestigious guide service in America. Teewinot is his ode to forty years in the mountains that he loves. Like Thoreau and Muir, Turner has contemplated the essential nature of a landscape. Teewinot is a book about a mountain range, its austere temper, its seasons, its flora and fauna, a few of its climbs, its weather, and the glory of the wildness. It is also about a small group of guides and rangers, nomads who inhabit the range each summer and know the mountains as intimately as they will ever be known. It is also a remarkable account of what it is like to live and work in a national park. Teewinot has something for everyone: spellbinding accounts of classic climbs, awe at the beauty of nature, and passion for some of the environmental issues facing America today. In this series of recollections, one of America's most beautiful national parks comes alive with beauty, mystery, and power. The beauty, mystery, and power of the Grand Tetons come alive in Jack Turner's memoir of a year on America's most beautiful mountain range.

    Powerful hunter, tireless swimmer, tender mother, gentle playmate — she is superbly adapted for surviving, even thriving, in this harsh and icy climate.

Just as the Inuit people have watched and learned from this amazing creature for generations, readers are invited to witness the majesty of Ice Bear.

    In 1905 an unknown 26-year-old clerk at the Swiss Patent Office, who had supposedly failed math in school, burst on to the scientific scene and swept away the hidebound theories of the day. The clerk, Albert Einstein, introduced a new and unexpected understanding of the universe and launched the two great revolutions of twentieth-century physics, relativity and quantum mechanics. The obscure origin and wide-ranging brilliance of the work recalled Isaac Newton’s “annus mirabilis” (miracle year) of 1666, when as a 23-year-old seeking safety at his family manor from an outbreak of the plague, he invented calculus and laid the foundations for his theory of gravity. Like Newton, Einstein quickly became a scientific icon--the image of genius and, according to Time magazine, the Person of the Century.The actual story is much more interesting. Einstein himself once remarked that “science as something coming into being ... is just as subjectively, psychologically conditioned as are all other human endeavors.” In this profile, the historian of science L. Randles Lagerstrom takes you behind the myth and into the very human life of the young Einstein. From family rifts and girlfriend troubles to financial hardships and jobless anxieties, Einstein’s early years were typical of many young persons. And yet in the midst of it all, he also saw his way through to profound scientific insights. Drawing upon correspondence from Einstein, his family, and his friends, Lagerstrom brings to life the young Einstein and enables the reader to come away with a fuller and more appreciative understanding of Einstein the person and the origins of his revolutionary ideas.About the cover image: While walking to work six days a week as a patent clerk in Bern, Switzerland, Einstein would pass by the famous "Zytglogge" tower and its astronomical clocks. The daily juxtaposition was fitting, as the relative nature of time and clock synchronization would be one of his revolutionary discoveries in the miracle year of 1905.
