Dale Purves - Brains: How They Seem to Work


Dale Purves - Brains: How They Seem to Work
Publisher: FT Press; 1 edition (April 19, 2010) | Language: English | ISBN-10: 0137055099 | EPUB + MOBI | 320 pages | 0.2 mb + 0.3 mb

For 50 years, the world’s most brilliant neuroscientists have struggled to understand how human brains really work. Today, says Dale Purves, the dominant research agenda may have taken us as far as it can—and neuroscientists may be approaching a paradigm shift.In this highly personal book, Purves reveals how we got to this point and offers his notion of where neuroscience may be headed next. Purves guides you through a half-century of the most influential ideas in neuroscience and introduces the extraordinary scientists and physicians who created and tested them. Purves offers a critical assessment of the paths that neuroscience research has taken, their successes and their limitations, and then introduces an alternative approach for thinking about brains. Building on new research on visual perception, he shows why common ideas about brain networks can’t be right and uncovers the factors that determine our subjective experience. The resulting insights offer a deeper understanding of what it means to be human.

In Defense of Food: An Eater's Manifesto


Michael Pollan, "In Defense of Food: An Eater's Manifesto" [Audiobook]
Pguin Audio | 2008 | ISBN: 0143142747 | MP3@96 kbps | 6 hrs 22 mins | 265.44 mb

Pollan provides another shocking yet essential treatise on the industrialized Western diet and its detrimental effects on our bodies and culture. Here he lays siege to the food industry and scientists' attempts to reduce food and the cultural practices of eating into bite-size concepts known as nutrients, and contemplates the follies of doing so. As an increasing number of Americans are overfed and undernourished, Pollan makes a strong argument for serious reconsideration of our eating habits and casts a suspicious eye on the food industry and its more pernicious and misleading practices. Listeners will undoubtedly find themselves reconsidering their own eating habits. Scott Brick, who narrated Pollan's The Omnivore's Dilemma, carries forward the same tone and consistency, thus creating a narrative continuity between the two books. Brick renders the text with an expert's skill, delivering well-timed pauses and accurate emphasis. He executes Pollan's asides and sarcasm with an uncanny ability thatmakes listening infinitely better than reading. So compelling is his tone, listeners may have trouble discerning whether Brick's conviction or talent drives his powerful performance.

What to eat, what not to eat, and how to think about health: a manifesto for our times

"Eat food. Not too much. Mostly plants." These simple words go to the heart of Michael Pollan's In Defense of Food, the well-considered answers he provides to the questions posed in the bestselling The Omnivore's Dilemma. Humans used to know how to eat well, Pollan argues. But the balanced dietary lessons that were once passed down through generations have been confused, complicated, and distorted by food industry marketers, nutritional scientists, and journalists—all of whom have much to gain from our dietary confusion. As a result, we face today a complex culinary landscape dense with bad advice and foods that are not "real." These "edible foodlike substances" are often packaged with labels bearing health claims that are typically false or misleading. Indeed, real food is fast disappearing from the marketplace, to be replaced by "nutrients," and plain old eating by an obsession with nutrition that is, paradoxically, ruining our health, not to mention our meals. Michael Pollan's sensible and decidedly counterintuitive advice is: "Don't eat anything that your great-great grandmother would not recognize as food."

Writing In Defense of Food, and affirming the joy of eating, Pollan suggests that if we would pay more for better, well-grown food, but buy less of it, we'll benefit ourselves, our communities, and the environment at large. Taking a clear-eyed look at what science does and does not know about the links between diet and health, he proposes a new way to think about the question of what to eat that is informed by ecology and tradition rather than by the prevailing nutrient-by-nutrient approach.

In Defense of Food reminds us that, despite the daunting dietary landscape Americans confront in the modern supermarket, the solutions to the current omnivore's dilemma can be found all around us.

In looking toward traditional diets the world over, as well as the foods our families—and regions—historically enjoyed, we can recover a more balanced, reasonable, and pleasurable approach to food. Michael Pollan's bracing and eloquent manifesto shows us how we might start making thoughtful food choices that will enrich our lives and enlarge our sense of what it means to be healthy.

Amazon.com Review
Amazon Significant Seven, January 2008: Food is the one thing that Americans hate to love and, as it turns out, love to hate. What we want to eat has been ousted by the notion of what we should eat, and it's at this nexus of hunger and hang-up that Michael Pollan poses his most salient question: where is the food in our food? What follows in In Defense of Food is a series of wonderfully clear and thoughtful answers that help us omnivores navigate the nutritional minefield that's come to typify our food culture. Many processed foods vie for a spot in our grocery baskets, claiming to lower cholesterol, weight, glucose levels, you name it. Yet Pollan shows that these convenient "healthy" alternatives to whole foods are appallingly inconvenient: our health has a nation has only deteriorated since we started exiling carbs, fats—even fruits—from our daily meals. His razor-sharp analysis of the American diet (as well as its architects and its detractors) offers an inspiring glimpse of what it would be like if we could (a la Humpty Dumpty) put our food back together again and reconsider what it means to eat well. In a season filled with rallying cries to lose weight and be healthy, Pollan's call to action—"Eat food. Not too much. Mostly plants."—is a program I actually want to follow. —Anne Bartholomew

thought about this book to introduce kids and aspiring gardeners to the wonderful benefits of natural gardening. If you continue to read on, you will discover the important roles that worms and garbage play when trying to grow something naturally or organically (as it is sometimes called). But more importantly, what I would really like for you to learn is that the real key to successful natural gardening is found in the soil.
For Ages 9 & Up.
The soil is the source of life. Often times we simply take soil as just one of the basic ingredients of start up gardening. However, as you know more about the soil, you will discover how it sustains not only plants but millions of micro-organisms, all happily participating in God perfect cycle of life. The soil is alive and we should learn to take care of it!
With this book I hope you will see how easy it is to grow things naturally and have some fun while you are at it!
And as you understand how plants should best be grown, I hope this book can also help you make healthier food choices in the ....

Stephen Hawking and Leonard Mlodinow - A Briefer History of Time


Stephen Hawking and Leonard Mlodinow - A Briefer History of Time
Audiobook | ISBN 10: 0553176986 | English | MP3 64.00 kbps | 183 MB

Editorial Reviews (amazon)
From Publishers Weekly
Starred Review. In the 17 years since the publication of A Brief History of Time, Dr. Hawking's bestselling exposition of physics, new data from particle physics and observational astronomy have shed light on efforts to find a Grand Unified Theory of Everything that Hawking and Mlodinow use to enhance and update their answers to basic questions about the universe: where it's going and how it began. Discussed at length are the mysterious dark matter and dark energy-both of which can only be observed by their gravitational effects and are believed to make up 90 percent of the universe. Another area of research that has exploded in the past 20 years is string theory. Hawking and Mlodinow provide one of the most lucid discussions of this complex topic ever written for a general audience. Readers will come away with an excellent understanding of the apparent contradictions and conundrums at the forefront of contemporary physics. Recognizing that much of their audience will also be science fiction buffs, they include a chapter on the possibility of time travel. "Don't bet on it," the authors advise. Throughout these discussions, the authors maintain the same wry, lively tone that made the original Brief History such a delight. They close with a discussion of where physics ends and philosophy begins, "Why does the universe exist at all?" They cannot provide the answer, but they do provide an immense amount of food for thought. Highly recommended.

From Scientific American
Hawking's A Brief History of Time, published in 1988, was a surprise best-seller but a tough read for most people who tackled it. Hawking received many requests for a version that would make his discussion of deep questions about the universe more accessible. This book does that. Hawking and Mlodinow, a physicist turned science writer, proceed by small and careful steps from the early history of astronomy to today's efforts to construct a grand unified theory of the universe.
