Although hints of a crisis appeared as early as the 1570s, the temperature by the end of the 16th century plummeted so drastically that Mediterranean harbors were covered with ice, birds literally dropped out of the sky, and "frost fairs" were erected on a frozen Thames - with kiosks, taverns, and even brothels that become a semi-permanent part of the city. Recounting the deep legacy and far-ranging consequences of this "Little Ice Age", acclaimed historian Philipp Blom reveals how the European landscape had subtly, but ineradicably, changed by the mid-17th century.

Australopithecines, dinosaurs, trilobites - such fossils conjure up images of lost worlds filled with vanished organisms. But in the full history of life, ancient animals, even the trilobites, form only the half-billion-year tip of a nearly four-billion-year iceberg. Andrew Knoll explores the deep history of life from its origins on a young planet to the incredible Cambrian explosion, presenting a compelling new explanation for the emergence of biological novelty.

Blockchain is the technology behind Bitcoin, the revolutionary "virtual currency" that's changing the way people do business. While Bitcoin has enjoyed some well-deserved hype, Blockchain may be Bitcoin's most vital legacy. Blockchain for Dummies is the ideal starting place for business pros looking to gain a better understanding of what Blockchain is, how it can improve the integrity of their data, and how it can work to fundamentally change their business and enhance their data security.

Is there a right way to study how the brain works? The most common approach involves the study of neural reactions to stimuli presented by an experimenter. György Buzsáki's The Brain from Inside Out examines why the outside-in framework for understanding brain function has become stagnant and points to new directions for understanding neural function. Building upon the success of 2011's Rhythms of the Brain, Professor Buzsáki presents the brain as a foretelling device that interacts with its environment through action and the examination of action's consequence.

On the Alaska Peninsula, where exceptional landscapes are commonplace, a small river attracts attention far beyond its scale. Each year, from summer to early fall, brown bears and salmon gather at Brooks River to create one of North America's greatest wildlife spectacles. As the salmon leap from the cascade, dozens of bears are there to catch them, and thousands of people come to watch in person or on the National Park Service's popular Brooks Falls Bearcam. The Bears of Brooks Falls tells the story of this region and the bears that made it famous.

"Ants are the most warlike of all animals, with colony pitted against colony.... Their clashes dwarf Waterloo and Gettysburg", writes Edward O. Wilson in his most finely observed work in decades. In a myrmecological tour to such far-flung destinations as Mozambique and New Guinea, the Gulf of Mexico's Dauphin Island and even his parents' overgrown yard back in Alabama, Wilson thrillingly evokes his nine-decade-long scientific obsession with more than 15,000 ant species.

One grey dismal day, Janine Marsh was on a trip to northern France to pick up some cheap wine. She returned to England a few hours later having put in an offer on a rundown old barn in the rural Seven Valleys area of Pas de Calais. This was not something she'd expected or planned for. Janine eventually gave up her job in London to move with her husband to live the good life in France. Or so she hoped. While getting to grips with the locals and la vie Française, and renovating her dilapidated new house, a building lacking the comforts of mains drainage, heating, or proper rooms.

In Three Roads to Quantum Gravity, Lee Smolin provides an accessible overview of the attempts to build a final "theory of everything." He explains in simple terms what scientists are talking about when they say the world is made from exotic entities such as loops, strings, and black holes and tells the fascinating stories behind these discoveries: the rivalries, epiphanies, and intrigues he witnessed firsthand.

In many ways, insects are just like us. Elaborate mating rituals, a variety of parenting styles, and a plethora of careers — from architects and engineers, to farmers and ranchers. Like us, they’re able to share complex information essential for survival, significantly impact their environment, and recycle. But insects outdo us in so many respects. They are terrestrial, but some can live underwater.

In this witty, often terrifying work of cultural criticism, Postman chronicles our transformation into a Technopoly: a society that no longer merely uses technology as a support system but instead is shaped by it. According to Postman, technology is rapidly gaining sovereignty over social institutions and national life to become self-justifying, self-perpetuating, and omnipresent. He warns that this will have radical consequences for the meanings of politics, art, religion, family, education, and more.

The Beginner's Guide to Raising Chickens makes it easy to start keeping these surprisingly smart birds right in your own backyard. From constructing coops to rearing chicks, you'll learn everything you need to know to make sure your chickens stay happy and healthy all year round.

If you are at all interested in life on our planet, then you need to know about insects. They are the most successful group of animals ever to have lived on Earth. Making up three-quarters of all animal species, insects conquered the planet long ago. They were among the very first animals to appear on land and were the first to take to the air. Their total biomass is at least 10 times that of all humans and our livestock combined. Join Dr. George McGavin on an exciting audio journey to help us understand the fascinating world of insects.

Clarence L. "Kelly" Johnson led the design of such crucial aircraft as the P-38 and Constellation, but he will be more remembered for the U-2 and SR-71 spy planes. His extraordinary leadership of the Lockheed "Skunk Works" cemented his reputation as a legendary figure in American aerospace management.

Today we are blessed with two extraordinarily successful theories of physics. The first is Albert Einstein's general theory of relativity, which describes the large-scale behavior of matter in a curved spacetime. The second is quantum mechanics. This theory describes the properties and behavior of matter and radiation at their smallest scales.

What caused the extinction of the dinosaurs? Walter Alvarez, one of the Berkeley scientists who discovered evidence of the impact, tells the story behind the development of the initially controversial theory. It is a saga of high adventure in remote locations, of arduous data collection and intellectual struggle, of long periods of frustration ended by sudden breakthroughs, of friendships made and lost, and of the exhilaration of discovery that forever altered our understanding of Earth's geological history.

Perhaps the greatest physicist of the second half of the 20th century, Richard Feynman changed the way we think about quantum mechanics, the most perplexing of all physical theories. Here Lawrence M. Krauss, himself a theoretical physicist and best-selling author, offers a unique scientific biography: a rollicking narrative coupled with clear and novel expositions of science at the limits.

The most important things in life are our health and happiness. Yet most of us are neither healthy nor happy. We have been led to believe that if we think ahead and make the right choices, we can manifest our dreams. Yet despite our best efforts, we still have more disease and discontent than ever before. Is it possible that our essential ideas about life are flawed? We are all aware of the impact of sunlight on a plant's growth and development. But few of us realize that a plant actually "sees" where light is emanating from and positions itself to be in optimal alignment with it.

Among the estimated 100 billion solar systems in the known universe, evolving life is surely abundant. That evolution is a process of "becoming" in each case. Since Newton, we have turned to physics to assess reality. But physics alone cannot tell us where we came from, how we arrived, and why our world has evolved past the point of unicellular organisms to an extremely complex biosphere.

This Very Short Introduction discusses the key concepts of biochemistry, as well as the historical figures in the field and the molecules they studied, before considering the current science and innovations in the field, and the interaction between biochemistry, biotechnology, and synthetic biology.

Michael Schneider leads us on a spectacular journey along the numbers one through 10 to explore the mathematical principles made visible in flowers, shells, crystals, plants, and the human body, expressed in the symbolic language of folk sayings and fairy tales, myth and religion, art and architecture. This is a new view of mathematics, not the one we learned at school but a comprehensive guide to the patterns that recur through the universe and underlie human affairs.
