And this updated edition contains a host of new findings on “Gemstones for Collectors,” additional gems in the “Table of Constants,” and the “double fraction” figures that experts have long wanted—a very special new feature.All the gemstones are treated in their many variations: more than 1,500 full-color photos showcase each precious and semiprecious stone in both its rough, natural, and its polished and cut renditions. Each entry offers complete information on the gemstone’s formation, structure, physical properties, and characteristics, along with the best methods of working, cutting, and polishing it. There are even full treatments of lesser-known gems, from andalusite to vesuvian, and a special section is devoted to rocks as precious stones, including alabaster, onyx, obsidian, and fossils. Organic gem materials are also covered, such as coral, ivory, amber, and pearl. Charts and tables help collectors identify unknown gemstones and check for genuineness.

    Join him as he perfects, simplifies, and totally re-invents your favorite dishes in surprising, spectacular ways.   Have you ever wondered which cheese, exactly, will make the stretchiest, cheesiest mac and cheese? Or if you can make Hollandaise sauce without fear, a double boiler, or even a whisk? Or if, instead of having to choose between onion rings or French fries, you can make onion rings crusted with French fries? Tyler Florence has. These are the kinds of questions he obsesses over when he thinks about how to make cooking both easier and more exciting.   For years, while shuttling between his restaurants and TV shoots, Tyler's kept a notebook of ideas to push his own recipes out of their comfort zone. Now, for the first time in his career, he’s established a culinary lab where he can dive deep into the hows, whys, and why-nots of his cooking. He brings you Inside the Test Kitchen to see his experiments, the wins and the fails, and of course, the delicious, foolproof, and surprising recipes that come out of it.   Go from tricks to make basics brilliant—like saucing Double-Creamed Spinach with pureed spinach, or using boiling-hot brine to make a Super-Crisp Roast Chicken— to simpler ways to make the classics, like a nearly no-stir Time Saver Risotto and a Three-Minute Hollandaise, to pure reinvention, like Fronion Rings and almost-instant Modern Burger Buns.   Through these 120 recipes, Tyler invites you to question culinary sacred cows, push your skills to the next level, and make food more delicious than they would have thought possible.

    In The Ends of the World, Peter Brannen dives into deep time, exploring Earth’s past dead ends, and in the process, offers us a glimpse of our possible future.Many scientists now believe that the climate shifts of the twenty-first century have analogs in these five extinctions. Using the visible clues these devastations have left behind in the fossil record, The Ends of the World takes us inside “scenes of the crime,” from South Africa to the New York Palisades, to tell the story of each extinction. Brannen examines the fossil record—which is rife with creatures like dragonflies the size of sea gulls and guillotine-mouthed fish—and introduces us to the researchers on the front lines who, using the forensic tools of modern science, are piecing together what really happened at the crime scenes of the Earth’s biggest whodunits.Part road trip, part history, and part cautionary tale, The Ends of the World takes us on a tour of the ways that our planet has clawed itself back from the grave, and casts our future in a completely new light.

    What with broken promises, complicated jargon and a lack of simple and clear information, is it any wonder that voter turnout is plummeting? It's not that you don't care about the way the country is run - it's that you don't think you can change it. Well, you can. And this book aims to show you how, by setting out basic politics and answering questions we've all asked, like: Why do politicians lie? What do UKIP stand for? And what's going to happen to the NHS? You have a decision to make in the countdown to the May 2015 General Election. You have something politicians want. Your vote. An ambassador for #SwingtheVote and the presenter of Free Speech, Rick Edwards has written a pithy and succinct book explaining the power of your vote. A refreshing counterpoint to Russell Brand's sentiments on voting in his latest book, Revolution, it will make you think about politics in a completely new way.
