The first is Albert Einstein's general theory of relativity, which describes the large-scale behaviour of matter in a curved spacetime. This theory is the basis for the standard model of big bang cosmology. The discoveryof gravitational waves at the LIGO observatory in the US (and then Virgo, in Italy) is only the most recent of this theory's many triumphs.The second is quantum mechanics. This theory describes the properties and behaviour of matter and radiation at their smallest scales. It is the basis for the standard model of particle physics, which builds up all the visible constituents of the universe out of collections of quarks, electrons andforce-carrying particles such as photons. The discovery of the Higgs boson at CERN in Geneva is only the most recent of this theory's many triumphs.But, while they are both highly successful, these two structures leave a lot of important questions unanswered. They are also based on two different interpretations of space and time, and are therefore fundamentally incompatible. We have two descriptions but, as far as we know, we've only ever hadone universe. What we need is a quantum theory of gravity.Approaches to formulating such a theory have primarily followed two paths. One leads to String Theory, which has for long been fashionable, and about which much has been written. But String Theory has become mired in problems. In this book, Jim Baggott describes the road less travelled: anapproach which takes relativity as its starting point, and leads to a structure called Loop Quantum Gravity. Baggott tells the story through the careers and pioneering work of two of the theory's most prominent contributors, Lee Smolin and Carlo Rovelli.

    His grand meteorological project had failed. Yet only a decade later, FitzRoy's storm warning system and "forecasts" would return, the model for what we use today.In an age when a storm at sea was evidence of God's wrath, nineteenth-century meteorologists had to fight against convention and religious dogma. Buoyed by the achievements of the Enlightenment, a generation of mavericks set out to decipher the secrets of the atmosphere and predict the future. Among them were Luke Howard, the first to classify clouds; Francis Beaufort, who quantified the winds; James Glaisher, who explored the upper atmosphere in a hot-air balloon; Samuel Morse, whose electric telegraph gave scientists the means by which to transmit weather warnings; and FitzRoy himself, master sailor, scientific pioneer, and founder of the U.K.'s national weather service.Reputations were built and shattered. Fractious debates raged over decades between scientists from London and Galway, Paris and New York. Explaining the atmosphere was one thing, but predicting what it was going to do seemed a step too far. In 1854, when a politician suggested to the Commons that Londoners might soon know the weather twenty-four hours in advance, the House roared with laughter.Peter Moore's The Weather Experiment navigates treacherous seas and rough winds to uncover the obsession that drove these men to great invention and greater understanding.

    When the seventh row of the periodic table of elements was completed in June 2016 with the addition of four final elements—nihonium, moscovium, tennessine, and oganesson—we at last could identify all the ingredients necessary to construct our world.In Elemental, chemist and science educator Tim James provides an informative, entertaining, and quirkily illustrated guide to the table that shows clearly how this abstract and seemingly jumbled graphic is relevant to our day-to-day lives.James tells the story of the periodic table from its ancient Greek roots, when you could count the number of elements humans were aware of on one hand, to the modern alchemists of the twentieth and twenty-first centuries who have used nuclear chemistry and physics to generate new elements and complete the periodic table. In addition to this, he answers questions such as: What is the chemical symbol for a human? What would happen if all of the elements were mixed together? Which liquid can teleport through walls? Why is the medieval dream of transmuting lead into gold now a reality?Whether you're studying the periodic table for the first time or are simply interested in the fundamental building blocks of the universe—from the core of the sun to the networks in your brain—Elemental is the perfect guide.

    Award-winning author Mary Cable recreates - in all its human and natural drama - the three-day debacle that began on the night of Sunday, March 11, 1888. We meet the heroes and villains alike as they struggle through the mounting snow and icy winds to keep the wheels of civilization from grinding to a halt. The Blizzard of 88 is a moving and dramatic history in the tradition of David McCullough's classic The Johnstown Flood.

    By dawn the next day, the city that hours earlier had stood as a symbol of America’s growth and expansion was now gone. Shattered, grief-stricken survivors emerged to witness a level of destruction never before seen: Eight thousand corpses littered the streets and were buried under the massive wreckage. Rushing water had lifted buildings from their foundations, smashing them into pieces, while wind gusts had upended steel girders and trestles, driving them through house walls and into sidewalks. No race or class was spared its wrath. In less than twenty-four hours, a single storm had destroyed a major American metropolis—and awakened a nation to the terrifying power of nature.Blending an unforgettable cast of characters, accessible weather science, and deep historical research into a sweeping and dramatic narrative, The Storm of the Century brings this legendary hurricane and its aftermath into fresh focus. No other natural disaster has ever matched the havoc caused by the awesome mix of winds, rain, and flooding that devastated Galveston and shocked a young, optimistic nation on the cusp of modernity. Exploring the impact of the tragedy on a rising country’s confidence—the trauma of the loss and the determination of the response—Al Roker illuminates the United States’s character at the dawn of the “American Century,” while also underlining the fact that no matter how mighty they may become, all nations must respect the ferocious potential of our natural environment.

    Two scientists, Peter Higgs and François Englert, whose theories predicted its existence, shared a Nobel Prize. The discovery was the culmination of the largest experiment ever run, the ATLAS and CMS experiments at CERN's Large Hadron Collider.But what really is a Higgs boson and what does it do? How was it found? And how has its discovery changed our understanding of the fundamental laws of nature? And what did it feel like to be part of it?Jon Butterworth is one of the leading physicists at CERN and this book is the first popular inside account of the hunt for the Higgs. It is a story of incredible scientific collaboration, inspiring technological innovation and ground-breaking science. It is also the story of what happens when the world's most expensive experiment blows up, of neutrinos that may or may not travel faster than light, and the reality of life in an underground bunker in Switzerland.This book will also leave you with a working knowledge of the new physics and what the discovery of the Higgs particle means for how we define the laws of nature. It will take you to the cutting edge of modern scientific thinking.

    In the next 40 hours of the "Super Outbreak," 148 record-breaking tornadoes tore through 13 states, from Michigan to Alabama. The twisters killed more than 300 people and left over 5,000 others injured. F5 recounts the nearly unbelievable destruction wrought by a "perfect storm" system that experts calculate could occur only once every 500 years. A truly riveting read.

    It was the deadliest day of the biggest tornado outbreak in recorded history, which saw 348 people killed, entire neighborhoods erased, and $11 billion in damage. The biggest of the tornadoes left scars across the land so wide they could be seen from space. But from the terrible destruction emerged everyday heroes, neighbors and strangers who rescued each other from hell on earth.With powerful emotion and gripping detail, Cross weaves together the heart-wrenching stories of several characters--including three college students, a celebrity weatherman, and a team of hard-hit rescuers--to create a nail-biting chronicle in the Tornado Alley of America. No, it's not Oklahoma or Kansas; it's Alabama, where there are more tornado fatalities than anywhere in the US, where the trees and hills obscure the storms until they're bearing down upon you. For some, it's a story of survival, and for others it's the story of their last hours.Cross's immersive reporting and dramatic storytelling sets you right in the middle of the very worst hit areas of Alabama, where thousands of ordinary people witnessed the sky falling around them. Yet from the disaster comes a redemptive message that's just as real: In times of trouble, the things that tear our world apart also reveal what holds us together.

    By the time the sun set over a ravaged plain, some 71 tornadoes had claimed 11,000 homes and businesses and caused a billion dollars in damages. One of them was a mile-wide monster of incredible power, the fiercest F5 twister to hit a metropolitan area, and whose 300 mph winds were the fastest ever recorded on the planet.Veteran journalist Nancy Mathis draws on numerous interviews to weave the story of those few terrifying hours that irrevocably changed the lives of many Oklahomans. "Storm Warning" features Kara Wiese, who fought to save her son from the fatal winds, and Charlie Cusack, who followed the tornado's progress on television until it came knocking on his front door. Amazingly, only thirty-eight people perished at the hands of the Oklahoma F5. Many lives were saved by the efforts of professionals such as Ted Fujita, the creator of the Fujita Scale (dubbed "Mr. Tornado" for his relentless pursuit to unravel a twister's mysteries); the oft-criticized but dogged government meteorologists; and Gary England, a resourceful TV weatherman whose tireless efforts prepared hundreds of people in the tornado's path. "Storm Warning" alternates between personal stories and the history of the struggle to understand this bewildering force of Mother Nature, creating a nail-biting, captivating look at surviving the fury from the skies.

    For the settlers the sight of a funnel cloud was an unearthly event. They called it "the Storm King" and their descriptions bordered on the supernatural: it glowed green or red, it whistled or moaned or sang. In Storm Kings, Lee Sandlin retraces America's fascination and unique relationship to tornadoes. From Ben Franklin's early experiments, to "the great storm debates" of the nineteenth century, to heartland life in the early twentieth century, Sandlin shows how tornado chasing helped foster the birth of meteorology, recreating with vivid descriptions some of the most devastating storms in America's history, including the "Tri-State tornado" of 1925 and the Peshtigo "fire tornado," whose deadly path of destruction was left encased in glass. Drawing on memoirs, letters, eyewitness testimonies, and numerous archives, Sandlin brings to life the forgotten characters and scientists-like James Espy, America's first meteorologist and Corporal John Park Finley, who helped place a network of weather "spotters" across the country-that changed a nation, detailing the almost invisible history of The National Weather Service, the settling of the Midwest, and how successive generations came to understand and finally coexist with the spiraling menace that could erase lives and whole towns in an instant.

    The Big Bang Cosmology is explored, looking at its observational successes in explaining the expansion of the Universe, the existence and properties of the cosmic microwave background, and the origin of light elements in the universe. Properties of the very early Universe are also covered, including the motivation for a rapid period of expansion known as cosmological inflation. The third edition brings this established undergraduate textbook up-to-date with the rapidly evolving observational situation. This fully revised edition of a bestseller takes an approach which is grounded in physics with a logical flow of chapters leading the reader from basic ideas of the expansion described by the Friedman equations to some of the more advanced ideas about the early universe. It also incorporates up-to-date results from the Planck mission, which imaged the anisotropies of the Cosmic Microwave Background radiation over the whole sky. The Advanced Topic sections present subjects with more detailed mathematical approaches to give greater depth to discussions. Student problems with hints for solving them and numerical answers are embedded in the chapters to facilitate the reader's understanding and learning. Cosmology is now part of the core in many degree programs. This current, clear and concise introductory text is relevant to a wide range of astronomy programs worldwide and is essential reading for undergraduates and Masters students, as well as anyone starting research in cosmology.

    To shape debates over health care, energy policy, space travel, and other vital issues, ordinary citizens must engage directly with research rather than relying on pundits’ and politicians’ interpretations. Otherwise, fringe opinions that have been discredited in the scientific community can take hold in the public imagination. At the same time, scientists must understand their roles as communicators and ambassadors as well as researchers.Rees not only diagnoses this central problem but also explains how scientists and the general public can deploy a global, long-term perspective to address the new challenges we face. In the process, he reveals critical shortcomings in our current system—for example, the tendency to be overly anxious about minor hazards while underrating the risk of potential catastrophes. Offering a strikingly clear portrait of the future of science, Rees tackles such diverse topics as the human brain, the possibility that humans will colonize other planets, and the existence of extraterrestrial life in order to distinguish between what scientists can hope to discover and what will always lie beyond our grasp.A fresh perspective on science’s significance and potential, From Here to Infinity will inspire and enlighten.
