Weaving together the cosmos' history and our own in an expanding intellectual adventure story, Dark Matter and the Dinosaurs takes us from the mysteries of dark matter and our cosmic environment to the conditions for life on Earth.Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter that is embedded in the plane of the Milky Way. Her research challenges the usual assumptions about the simple nature of dark matter and demonstrates how scientists formulate and establish new ideas. In a sense, it might have been dark matter that killed the dinosaurs.With her unique and wide-ranging perspective, Randall connects dark matter to the history of the world in the broadest terms. Bringing in pop culture and social and political viewpoints, she shares with us the latest findings—established and speculative—regarding dark matter, the cosmos, the galaxy, asteroids, comets, and impacts, as well as life's development and extinctions. Randall makes clear how connected the planet is to the makeup of the Universe, but also how fragile our place in the Universe, which evolved over billions of years, might be.In this brilliant and fresh exploration of our cosmic environment, Professor Randall explains the underlying science of our world in the breathtaking tale of a Universe in which the small and the large, the visible and the hidden are intimately related. Dark Matter and the Dinosaurs illuminates the deep relationships that are critical to our world as well as the astonishing beauty of the structures and connections that surround us. It's impossible to read this book and look at either Earth or sky again in the same way.

    Forever. But here’s the thing about crazy: It. Wants. Out.” In Scrappy Little Nobody, she invites readers inside her brain, sharing extraordinary and charmingly ordinary stories with candor and winningly wry observations.With her razor-sharp wit, Anna recounts the absurdities she’s experienced on her way to and from the heart of pop culture as only she can—from her unusual path to the performing arts (Vanilla Ice and baggy neon pants may have played a role) to her double life as a middle-school student who also starred on Broadway to her initial “dating experiments” (including only liking boys who didn’t like her back) to reviewing a binder full of butt doubles to her struggle to live like an adult woman instead of a perpetual “man-child.”Enter Anna’s world and follow her rise from “scrappy little nobody” to somebody who dazzles on the stage, the screen, and now the page—with an electric, singular voice, at once familiar and surprising, sharp and sweet, funny and serious (well, not that serious).

    Everyone knows this. Each of us contributes his share. But we tend to take the situation for granted. Most people are rather confident of their ability to recognize bullshit and to avoid being taken in by it. So the phenomenon has not aroused much deliberate concern. We have no clear understanding of what bullshit is, why there is so much of it, or what functions it serves. And we lack a conscientiously developed appreciation of what it means to us. In other words, as Harry Frankfurt writes, "we have no theory."Frankfurt, one of the world's most influential moral philosophers, attempts to build such a theory here. With his characteristic combination of philosophical acuity, psychological insight, and wry humor, Frankfurt proceeds by exploring how bullshit and the related concept of humbug are distinct from lying. He argues that bullshitters misrepresent themselves to their audience not as liars do, that is, by deliberately making false claims about what is true. In fact, bullshit need not be untrue at all.Rather, bullshitters seek to convey a certain impression of themselves without being concerned about whether anything at all is true. They quietly change the rules governing their end of the conversation so that claims about truth and falsity are irrelevant. Frankfurt concludes that although bullshit can take many innocent forms, excessive indulgence in it can eventually undermine the practitioner's capacity to tell the truth in a way that lying does not. Liars at least acknowledge that it matters what is true. By virtue of this, Frankfurt writes, bullshit is a greater enemy of the truth than lies are.

    Dozens died of radiation poisoning, fallout contaminated half the continent, and thousands fell ill.In Chernobyl, Serhii Plokhy draws on new sources to tell the dramatic stories of the firefighters, scientists, and soldiers who heroically extinguished the nuclear inferno. He lays bare the flaws of the Soviet nuclear industry, tracing the disaster to the authoritarian character of the Communist party rule, the regime's control over scientific information, and its emphasis on economic development over all else.Today, the risk of another Chernobyl looms in the mismanagement of nuclear power in the developing world. A moving and definitive account, Chernobyl is also an urgent call to action.
