Here he explains how our image of the world has changed throughout centuries. Fom Aristotle to Albert Einstein, Michael Faraday to the Higgs boson, he takes us on a wondrous journey to show us that beyond our ever-changing idea of reality is a whole new world that has yet to be discovered.

    But its toxic effects on society are plain to see—feeding white nationalism, fueling hatred, endangering lives, and corroding our discourse on everything from sports to intelligence. Even well-intentioned people repeat stereotypes based on “science,” because cutting-edge genetics are hard to grasp—and all too easy to distort. Paradoxically, these misconceptions are multiplying even as scientists make unprecedented discoveries in human genetics—findings that, when accurately understood, are powerful evidence against racism. We’ve never had clearer answers about who we are and where we come from, but this knowledge is sorely needed in our casual conversations about race.How to Argue With a Racist emphatically dismantles outdated notions of race by illuminating what modern genetics actually can and can’t tell us about human difference. We now know that the racial categories still dividing us do not align with observable genetic differences. In fact, our differences are so minute that, most of all, they serve as evidence of our shared humanity.

    This authoritative yet accessible study is the ultimate astronomy lesson. Combining fascinating and often alarming scenarios that seem plucked from science fiction with the latest research and opinions, Plait illustrates why outer space is not as remote as most people think. Each chapter explores a different phenomenon, explaining it in easy-to-understand terms, and considering how life on earth and the planet itself would be affected should the event come to pass. Rather than sensationalizing the information, Plait analyzes the probability of these catastrophes occurring in our lifetimes and what we can do to stop them. With its entertaining tone and enlightening explanation of unfathomable concepts, Death from the Skies! will appeal to science buffs and beginners alike.

    It has been inspired by the scientific ferment that swept through Britain at the end of the 18th century, and which Holmes now radically redefines as 'the revolution of Romantic Science'.

    Told in the same fanciful, irreverent style as the Hitchhiker trilogy, with scraps of scripts, letters and comments from Adams, Don't Panic is the perfect companion to one of the most successful series in publishing history.

    After its founding in 509 BCE, Rome grew from an unremarkable Italian city-state to the dominant superpower of the Mediterranean world. Through it all, the Romans never allowed a single man to seize control of the state. Every year for four hundred years the annually elected consuls voluntarily handed power to their successors. Not once did a consul give in to the temptation to grab absolute power and refuse to let it go. It was a run of political self-denial unmatched in the history of the world. The disciplined Roman republicans then proceeded to explode out of Italy and conquer a world filled with petty tyrants, barbarian chieftains, and despotic kings.But the very success of the Republic proved to be its undoing. The republican system was unable to cope with the vast empire Rome ruled. Bankrolled by mountains of imperial wealth and without a foreign enemy to keep them united, ambitious Roman leaders began to stray from the republican austerity of their ancestors. Almost as soon as they had conquered the Mediterranean, Rome would become engulfed in violent political conflicts and civil wars that would destroy the Republic less than a century later.The Storm Before the Storm tells the story of the beginning of the end of the Roman Republic--the story of the first generation that had to cope with the dangerous new political environment made possible by Rome's unrivaled domination over the known world. The tumultuous years from 133-80 BCE set the stage for the fall of the Republic.The Republic faced issues like rising economic inequality, increasing political polarization, the privatization of the military, endemic social and ethnic prejudice, rampant corruption, ongoing military quagmires, and the ruthless ambition and unwillingness of elites to do anything to reform the system in time to save it--a situation that draws many parallels to present-day America. These issues are among the reasons why the Roman Republic would fall. And as we all know, those who do not learn from history are doomed to repeat it.

    Breaking down the symbols themselves, they pose a series of questions: What is energy? What is mass? What has the speed of light got to do with energy and mass? In answering these questions, they take us to the site of one of the largest scientific experiments ever conducted. Lying beneath the city of Geneva, straddling the Franco-Swiss boarder, is a 27 km particle accelerator, known as the Large Hadron Collider. Using this gigantic machine—which can recreate conditions in the early Universe fractions of a second after the Big Bang—Cox and Forshaw will describe the current theory behind the origin of mass.Alongside questions of energy and mass, they will consider the third, and perhaps, most intriguing element of the equation: 'c' - or the speed of light. Why is it that the speed of light is the exchange rate? Answering this question is at the heart of the investigation as the authors demonstrate how, in order to truly understand why E=mc2, we first must understand why we must move forward in time and not backwards and how objects in our 3-dimensional world actually move in 4-dimensional space-time. In other words, how the very fabric of our world is constructed. A collaboration between two of the youngest professors in the UK, Why Does E=mc2? promises to be one of the most exciting and accessible explanations of the theory of relativity in recent years.

    Our Big Bang, our distant future, parallel worlds, the sub-atomic and intergalactic - none of them are what they seem. But there is a way to understand this immense strangeness - mathematics. Seeking an answer to the fundamental puzzle of why our universe seems so mathematical, Tegmark proposes a radical idea: that our physical world not only is described by mathematics, but that it is mathematics. This may offer answers to our deepest questions: How large is reality? What is everything made of? Why is our universe the way it is?Table of ContentsPreface 1 What Is Reality?

    This idea is considered a foundation of modern physics, but what if it is wrong? Theoretical physicist Magueijo presents the idea that light traveled faster in the early universe than it does today. The varying speed of light theory solves some of the most intractable problems in cosmology, and could have major implications for the study of physics.

    Her actions sparked a global movement, inspiring millions of students to go on strike for our planet, forcing governments to listen, and earning her a Nobel Peace Prize nomination.No One Is Too Small to Make A Difference brings you Greta in her own words, for the first time. Collecting her speeches that have made history across the globe, from the United Nations to Capitol Hill and mass street protests, her book is a rallying cry for why we must all wake up and fight to protect the living planet, no matter how powerless we feel. Our future depends upon it.

    These are the stories of life inside the courtroom. They are sometimes funny, often moving and ultimately life-changing. How can you defend a child-abuser you suspect to be guilty? What do you say to someone sentenced to ten years who you believe to be innocent? What is the law and why do we need it? And why do they wear wigs? From the criminals to the lawyers, the victims, witnesses and officers of the law, here is the best and worst of humanity, all struggling within a broken system which would never be off the front pages if the public knew what it was really like. This is a first-hand account of the human cost of the criminal justice system, and a guide to how we got into this mess, The Secret Barrister shows you what it’s really like and why it really matters.

    In the hands of one of today’s hottest young physicists, that simple fact of breakfast becomes a doorway to understanding the Big Bang, the universe, and other universes, too. In From Eternity to Here, Sean Carroll argues that the arrow of time, pointing resolutely from the past to the future, owes its existence to conditions before the Big Bang itself, a period modern cosmology of which Einstein never dreamed. Increasingly, though, physicists are going out into realms that make the theory of relativity seem like child’s play. Carroll’s scenario is not only elegant, it’s laid out in the same easy-to- understand language that has made his group blog, Cosmic Variance, the most popular physics blog on the Net. From Eternity to Here uses ideas at the cutting edge of theoretical physics to explore how properties of spacetime before the Big Bang can explain the flow of time we experience in our everyday lives. Carroll suggests that we live in a baby universe, part of a large family of universes in which many of our siblings experience an arrow of time running in the opposite direction. It’s an ambitious, fascinating picture of the universe on an ultra-large scale, one that will captivate fans of popular physics blockbusters like Elegant Universe and A Brief History of Time.

    In this narrative, Walter Isaacson explains how his mind worked and the mysteries of the universe that he discovered.

    But are there limits to what we can discover about our physical universe?In this very personal journey to the edges of knowledge, Marcus du Sautoy investigates how leading experts in fields from quantum physics and cosmology, to sensory perception and neuroscience, have articulated the current lie of the land. In doing so, he travels to the very boundaries of understanding, questioning contradictory stories and consulting cutting edge data.Is it possible that we will one day know everything? Or are there fields of research that will always lie beyond the bounds of human comprehension? And if so, how do we cope with living in a universe where there are things that will forever transcend our understanding?In What We Cannot Know, Marcus du Sautoy leads us on a thought-provoking expedition to the furthest reaches of modern science. Prepare to be taken to the edge of knowledge to find out if there’s anything we truly cannot know.

    Bejan explores controversial and relevant issues such as sustainability, water and food supply, fuel, and economy, to critique the state in which the world understands positions of power and freedom. Breaking down concepts such as desire and power, sports health and culture, the state of economy, water and energy, politics and distribution, Bejan uses the language of physics to explain how each system works in order to clarify the meaning of evolution in its broadest scientific sense, moving the reader towards a better understand of the world's systems and the natural evolution of cultural and political development. What Life Is argues that the evolution phenomenon is much broader and older than the evolutionary designs that constitute the biosphere, empowering readers with a new view of the globe, revealing that the urge to have better ideas has the same physical effect as the urge to have better laws and better government. This is evolution explained loudly but also elegantly, forging a path that flows sustainability.
