But if we are supposedly evolution’s greatest creation, why do we have such bad knees? Why do we catch head colds so often—two hundred times more often than a dog does? How come our wrists have so many useless bones? Why is the vast majority of our genetic code pointless? And are we really supposed to swallow and breathe through the same narrow tube? Surely there’s been some kind of mistake. As professor of biology Nathan H. Lents explains in Human Errors, our evolutionary history is nothing if not a litany of mistakes, each more entertaining and enlightening than the last. The human body is one big pile of compromises. But that is also a testament to our greatness: as Lents shows, humans have so many design flaws precisely because we are very, very good at getting around them.   A rollicking, deeply informative tour of humans’ four billion year long evolutionary saga, Human Errors both celebrates our imperfections and offers an unconventional accounting of the cost of our success.

    So little, in fact, that scientists and philosophers have, for centuries, been obsessed with what has become known as the “eel question”: Where do eels come from? What are they? Are they fish or some other kind of creature altogether? Even today, in an age of advanced science, no one has ever seen eels mating or giving birth, and we still don’t understand what drives them, after living for decades in freshwater, to swim great distances back to the ocean at the end of their lives. They remain a mystery.Drawing on a breadth of research about eels in literature, history, and modern marine biology, as well as his own experience fishing for eels with his father, Patrik Svensson writes a book about this unusual animal. In The Book of Eels, we meet renowned historical thinkers, from Aristotle to Sigmund Freud to Rachel Carson, for whom the eel was a singular obsession. And we meet the scientists who spearheaded the search for the eel’s point of origin, including Danish marine biologist Johannes Schmidt, who led research efforts in the early twentieth century, catching thousands upon thousands of eels, in the hopes of proving their birthing grounds in the Sargasso Sea.Blending memoir and nature writing, Svensson’s journey to understand the eel becomes an exploration of the human condition that delves into overarching issues about our roots and destiny, both as humans and as animals, and, ultimately, how to handle the biggest question of all: death.

    History at its most interesting is complex, a fascinating whirl of events, personalities, and forces, and few periods of history offer us such captivating complexity as Europe's 19th "century"—the often-broadly defined period from the French Revolution to World War I that formed the foundation of the modern world.How was that foundation built? And what did that transition to modernity mean for peasants, workers, the middle class, aristocrats, women, and minorities?Why did an era that began with the idealism of the French Revolution and the power of the Industrial Revolution culminate in the chaos of World War I, considered by most historians to be the greatest tragedy of modern European history? Did nationalism and imperialism inevitably lead in such a direction, or were there other factors involved?Even these questions, as important as they are, can only hint at the complexity of this period, just as this course can really only put us on a path toward the answers.

    It intersects with Darwin’s theory of evolution, and collides with the horrors of Nazi eugenics in the 1940s. The gene transforms post-war biology. It reorganizes our understanding of sexuality, temperament, choice and free will. This is a story driven by human ingenuity and obsessive minds – from Charles Darwin and Gregor Mendel to Francis Crick, James Watson and Rosalind Franklin, and the thousands of scientists still working to understand the code of codes.This is an epic, moving history of a scientific idea coming to life, by the author of The Emperor of All Maladies. But woven through The Gene, like a red line, is also an intimate history – the story of Mukherjee’s own family and its recurring pattern of mental illness, reminding us that genetics is vitally relevant to everyday lives. These concerns reverberate even more urgently today as we learn to “read” and “write” the human genome – unleashing the potential to change the fates and identities of our children.Majestic in its ambition, and unflinching in its honesty, The Gene gives us a definitive account of the fundamental unit of heredity – and a vision of both humanity’s past and future.

    The Cave and the Light is a magisterial account of how the two greatest thinkers of the ancient world, Plato and Aristotle, laid the foundations of Western culture—and how their rivalry shaped the essential features of our culture down to the present day.   Plato came from a wealthy, connected Athenian family and lived a comfortable upper-class lifestyle until he met an odd little man named Socrates, who showed him a new world of ideas and ideals. Socrates taught Plato that a man must use reason to attain wisdom, and that the life of a lover of wisdom, a philosopher, was the pinnacle of achievement. Plato dedicated himself to living that ideal and went on to create a school, his famed Academy, to teach others the path to enlightenment through contemplation.   However, the same Academy that spread Plato’s teachings also fostered his greatest rival. Born to a family of Greek physicians, Aristotle had learned early on the value of observation and hands-on experience. Rather than rely on pure contemplation, he insisted that the truest path to knowledge is through empirical discovery and exploration of the world around us. Aristotle, Plato’s most brilliant pupil, thus settled on a philosophy very different from his instructor’s and launched a rivalry with profound effects on Western culture.   The two men disagreed on the fundamental purpose of the philosophy. For Plato, the image of the cave summed up man’s destined path, emerging from the darkness of material existence to the light of a higher and more spiritual truth. Aristotle thought otherwise. Instead of rising above mundane reality, he insisted, the philosopher’s job is to explain how the real world works, and how we can find our place in it. Aristotle set up a school in Athens to rival Plato’s Academy: the Lyceum. The competition that ensued between the two schools, and between Plato and Aristotle, set the world on an intellectual adventure that lasted through the Middle Ages and Renaissance and that still continues today.   From Martin Luther (who named Aristotle the third great enemy of true religion, after the devil and the Pope) to Karl Marx (whose utopian views rival Plato’s), heroes and villains of history have been inspired and incensed by these two master philosophers—but never outside their influence.   Accessible, riveting, and eloquently written, The Cave and the Light provides a stunning new perspective on the Western world, certain to open eyes and stir debate.Praise for The Cave and the Light   “A sweeping intellectual history viewed through two ancient Greek lenses . . . breezy and enthusiastic but resting on a sturdy rock of research.”—Kirkus Reviews   “Examining mathematics, politics, theology, and architecture, the book demonstrates the continuing relevance of the ancient world.”—Publishers Weekly  “A fabulous way to understand over two millennia of history, all in one book.”—Library Journal  “Entertaining and often illuminating.”—The Wall Street JournalFrom the Hardcover edition.

    

    The consequences of losing beavers were profound: streams eroded, wetlands dried up, and species from salmon to swans lost vital habitat. Today, a growing coalition of “Beaver Believers”―including scientists, ranchers, and passionate citizens―recognizes that ecosystems with beavers are far healthier, for humans and non-humans alike, than those without them. From the Nevada deserts to the Scottish highlands, Believers are now hard at work restoring these industrious rodents to their former haunts. Eager is a powerful story about one of the world’s most influential species, how North America was colonized, how our landscapes have changed over the centuries, and how beavers can help us fight drought, flooding, wildfire, extinction, and the ravages of climate change. Ultimately, it’s about how we can learn to coexist, harmoniously and even beneficially, with our fellow travelers on this planet.

    These 24 intriguing and enlightening lectures lay bare the inner workings of our minds – and it's all brought to you by award-winning Professor Stephen P. Hinshaw, an instructor whose training as a clinical psychologist straddles both the science of the mind and its impact on individual lives. His comprehensive and unbiased approach to this subject reveals how the science of the human mind applies to the life of our species – and to your own life as well.

    It starts in your mother's womb, accelerates to high speed in infancy and childhood, and continues through every age, whether you're actively engaged in mastering a new skill, intuitively discovering an unfamiliar place, or just sleeping, which is fundamental to helping you consolidate and hold on to what you've learned. You are truly born to learn around the clock.But few of us know how we learn, which is the key to learning and studying more effectively. For example, you may be surprised by the following:People tend to misjudge what they have learned well, what they don't yet know, and what they do and do not need to practice.Moments of confusion, frustration, uncertainty, and lack of confidence are part of the process of acquiring new skills and new knowledge.Humans and animals explore their worlds for the sake of learning, regardless of rewards and punishment connected with success.You can teach an old dog new tricks. In fact, older learners have the benefit of prior knowledge and critical skills—two advantages in learning.Shedding light on what's going on when we learn and dispelling common myths about the subject, How We Learn introduces you to this practical and accessible science in 24 half-hour lectures presented by Professor Monisha Pasupathi of the University of Utah, an award-winning psychology teacher and expert on how people of all ages learn.

    Discover the secrets behind the words in our everyday lexicon with this delightful, informative survey of English, from its Germanic origins to the rise of globalization and cyber-communications. Professor Curzan approaches words like an archaeologist, digging below the surface to uncover the story of words, from the humble "she" to such SAT words as "conflagration" and "pedimanous." In these 36 fascinating lectures, you'll discover the history of the dictionary and how words make it into a reference book like the Oxford English Dictionary; survey the borrowed words that make up the English lexicon; find out how words are born and how they die; expand your vocabulary by studying Greek and Latin "word webs"; and revel in new terms, such as "musquirt," "adorkable," and "struggle bus." English is an omnivorous language and has borrowed heavily from the many languages it has come into contact with, from Celtic and Old Norse in the Middle Ages to the dozens of world languages in the truly global 20th and 21st centuries. You'll be surprised to learn that the impulse to conserve "pure English" is nothing new. In fact, if English purists during the Renaissance had their way, we would now be using Old English compounds such as "flesh-strings" for "muscles" and "bone-lock" for "joint." You may not come away using terms like "whatevs" or "multislacking" in casual conversation, but you'll love studying the linguistic system that gives us such irreverent - and fun - slang, from "boy toy" to "cankles."

    See ISBN 9780465094646History is full of strange animal stories invented by the brightest and most influential, from Aristotle to Disney. But when it comes to understanding animals, we’ve got a long way to go.Whether we’re watching a viral video of romping baby pandas or looking at a picture of penguins ‘holding hands’, we often project our own values – innocence, abstinence, hard work – onto animals. So you’ve probably never considered that moose get drunk and that penguins are notorious cheats.In The Unexpected Truth About Animals Zoologist Lucy unravels many such myths – that eels are born from sand, that swallows hibernate under water, and that bears gave birth to formless lumps that are licked into shape by their mothers – to show that the stories we create reveal as much about us as they do about the animals.Astonishing, illuminating and laugh-out-loud funny.

    Over millennia, philosophers, theologians, and mathematicians have all weighed in on the topic, and in recent centuries, economists, psychologists, and sociologists have joined the investigation. Now, you can learn what science has revealed about how we make choices. In How You Decide: The Science of Human Decision Making, Professor Ryan Hamilton, Associate Professor of Marketing at Emory University's Goizueta Business School, uses research revealed via the scientific method to understand and explain human decision making. Incorporating the outcomes of his own published experiments and those of his esteemed peers, Dr. Hamilton presents information that allows you to better understand the choices you face every day, the tools you can use to make the best decisions for your personal goals, and how to most effectively influence the decisions of others.
