In the book, Sagan explores 15 billion years of cosmic evolution and the development of science and civilization. Cosmos traces the origins of knowledge and the scientific method, mixing science and philosophy, and speculates to the future of science. The book also discusses the underlying premises of science by providing biographical anecdotes about many prominent scientists throughout history, placing their contributions into the broader context of the development of modern science.The book covers a broad range of topics, comprising Sagan's reflections on anthropological, cosmological, biological, historical, and astronomical matters from antiquity to contemporary times. Sagan reiterates his position on extraterrestrial life—that the magnitude of the universe permits the existence of thousands of alien civilizations, but no credible evidence exists to demonstrate that such life has ever visited earth.

    

    This astonishing device, responsible for storing and retrieving vast quantities of information that can be accessed at a moment's notice, is the human brain. How does such a dynamic and powerful machine make memories, learn a language, and remember how to drive a car? What habits can we adopt in order to learn more effectively throughout our lives? And how do external factors like traumatic injuries and mood affect our gray matter? The answers to these questions are merely the tip of the iceberg in The Learning Brain.These 24 half-hour lectures offer in-depth and surprising lessons about how the brain learns and how we can optimize that learning. Begin your journey by focusing on which parts of the brain are responsible for different kinds of memory, from personal experiences and memorized facts to short-term memory, and how these systems work on a psychological and biological level. Then, discover how to better absorb and retain all kinds of memories in all stages of life. This course is chock-full of valuable information, whether you're learning a new language at 60 or discovering calculus at 16. If you need better study habits, struggle with learning a new skill, or just worry about memories fading with age, The Learning Brain will provide illuminating insights.Take this journey with Thad Polk, professor of psychology at the University of Michigan, whose well-organized curriculum and relaxed teaching style ease you into intricate aspects of learning science, including the underlying cognitive and neural mechanisms involved. Professor Polk's credentials in psychology and over 20 years' experience in education shine through every lecture of The Learning Brain as he firmly supports this rigorous exploration with scientific studies conducted over the last several decades of neuroscientific research.Listening Length: 12 hours and 23 minutes

    But natural selection has given us a suite of beneficial social features, including our capacity for love, friendship, cooperation, and learning. Beneath all of our inventions -- our tools, farms, machines, cities, nations -- we carry with us innate proclivities to make a good society.In Blueprint, Nicholas A. Christakis introduces the compelling idea that our genes affect not only our bodies and behaviors, but also the ways in which we make societies, ones that are surprisingly similar worldwide.With many vivid examples -- including diverse historical and contemporary cultures, communities formed in the wake of shipwrecks, commune dwellers seeking utopia, online groups thrown together by design or involving artificially intelligent bots, and even the tender and complex social arrangements of elephants and dolphins that so resemble our own -- Christakis shows that, despite a human history replete with violence, we cannot escape our social blueprint for goodness.In a world of increasing political and economic polarization, it's tempting to ignore the positive role of our evolutionary past. But by exploring the ancient roots of goodness in civilization, Blueprint shows that our genes have shaped societies for our welfare and that, in a feedback loop stretching back many thousands of years, societies are still shaping our genes today.

    Why does a simple incident like a traffic jam affect you the way it does? What makes you act the way you do around your friends and family? Why do you often see the world so differently from the way other people see it? The answer to these questions and more really comes down to one thing: your personality.

    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.

    Darwin wondered why these birds were confined to remote islands at the tip of South America, sensing a larger story, but he set this mystery aside and never returned to it. Almost two hundred years later, Jonathan Meiburg takes up this chase. He takes us through South America, from the fog-bound coasts of Tierra del Fuego to the tropical forests of Guyana, in search of these birds: striated caracaras, which still exist, though they're very rare. He reveals the wild, fascinating story of their history, origins, and possible futures. And along the way, he draws us into the life and work of William Henry Hudson, the Victorian writer and naturalist who championed caracaras as an unsung wonder of the natural world, and to falconry parks in the English countryside, where captive caracaras perform incredible feats of memory and problem-solving. A Most Remarkable Creature is a hybrid of science writing, travelogue, and biography, as generous and accessible as it is sophisticated, and absolutely riveting.

    Sapolsky's storytelling concept is delightful but it also has a powerful intrinsic logic: he starts by looking at the factors that bear on a person's reaction in the precise moment a behavior occurs, and then hops back in time from there, in stages, ultimately ending up at the deep history of our species and its evolutionary legacy.And so the first category of explanation is the neurobiological one. A behavior occurs--whether an example of humans at our best, worst, or somewhere in between. What went on in a person's brain a second before the behavior happened? Then Sapolsky pulls out to a slightly larger field of vision, a little earlier in time: What sight, sound, or smell caused the nervous system to produce that behavior? And then, what hormones acted hours to days earlier to change how responsive that individual is to the stimuli that triggered the nervous system? By now he has increased our field of vision so that we are thinking about neurobiology and the sensory world of our environment and endocrinology in trying to explain what happened.Sapolsky keeps going: How was that behavior influenced by structural changes in the nervous system over the preceding months, by that person's adolescence, childhood, fetal life, and then back to his or her genetic makeup? Finally, he expands the view to encompass factors larger than one individual. How did culture shape that individual's group, what ecological factors millennia old formed that culture? And on and on, back to evolutionary factors millions of years old.The result is one of the most dazzling tours d'horizon of the science of human behavior ever attempted, a majestic synthesis that harvests cutting-edge research across a range of disciplines to provide a subtle and nuanced perspective on why we ultimately do the things we do...for good and for ill. Sapolsky builds on this understanding to wrestle with some of our deepest and thorniest questions relating to tribalism and xenophobia, hierarchy and competition, morality and free will, and war and peace. Wise, humane, often very funny, Behave is a towering achievement, powerfully humanizing, and downright heroic in its own right.

    By studying the physical astronomy of all the planets in the Solar System, we can attempt to understand their true nature. Ultimately, these lectures will bring us to a greater understanding of the Solar System's creation, which brings us again back to the beginning and what it means to us as we look outward from our rotating Earth.

    Each professor addresses an area of personal expertise and focuses not only on the matter at hand, but on the larger story-on the links between the works and the figures discussed. The lectures address-in chronological sequence-a series of major works that have shaped the ongoing development of Western thought both in their own right and in cultural dialogue with other traditions. In the process, the course engages many of the most perennial and far-reaching questions that we face in our daily lives.Lecture 1 From Sumer to AthensLecture 2 The Epic of GilgameshLecture 3 The Hebrew Bible: Historical Background and GenesisLecture 4 The Hebrew Bible: Exodus and the CovenantLecture 5 The Hebrew Bible: Psalms, Prophets, The Song of Songs, and JobLecture 6 Greece: From the Bronze Age to the Archaic AgeLecture 7 The IliadLecture 8 Homer: The OdysseyLecture 9 Hesiod and Lyric PoetryLecture 10 Greek Tragedy: AeschylusLecture 11 Greek Tragedy: SophoclesLecture 12 Greek Tragedy: EuripidesLecture 13 Herodotus of HalicarnassusLecture 14 Greek Art

    CBT illuminates the links between thoughts, emotions, behaviors, and physical health and uses those connections to develop concrete plans for self-improvement. Built on a solid foundation of neurological and behavioral research, CBT is an approach almost anyone can use for promoting greater mental health and improving quality of life. In 24 engaging half-hour lectures, you'll build a robust and effective self-improvement toolkit with the expert guidance of Professor Satterfield of the University of California, San Francisco. You will explore CBT's roots in Socratic and stoic philosophy, build a toolkit of CBT techniques, and hear about the latest research about its outcomes. Additionally this intriguing and practical course allows you to take on the role of medical student, physician, psychologist, and patient. Throughout the course you'll explore issues that cause people to seek out therapy. In some cases you'll get to hear Dr. Satterfield working with a patient, and in others you'll be delving into research to find what causes issues and how CBT helps to resolve them. Everyone has something about their life that they would like to improve. With the tools in CBT and the desire to make your situation better, you can create lasting change in your life.

    Professor Ridgley has crafted these 24 lectures as an accessible way to engage with thinking that will help you think-and act-more strategically in business and in your own life, whether you're the CEO of a Fortune 500 company or you're preparing to embark on a new career path.These lectures are loosely organized around several key topics central to effective strategic thinking, including: principles of conflict (in which you'll follow the development of strategic theory from its roots in great military campaigns to its modern applications in business); competitive intelligence (which plays an increasingly important role in strategic thinking); and tools of strategy and analysis (which can aid your understanding of the forces that shape our future and can help you make sense of a rapidly changing world).Central to these lectures are the tools and tricks that strategic thinkers have used to better approach problems and seek lasting solutions. Among those you'll learn how to use are the indirect approach (which offers you a much greater utility in achieving your objectives without approaching your opponent head-on); the value chain (a method that divides your team or organization into its value - producing activities so you can better inform yourself on its internal strengths and weaknesses; and the four actions framework (in which you ask yourself four questions to challenge your established logic in an effort to gain a stronger competitive advantage).

    Most scholars are historians of either Greek or Roman history and perform research solely in that specific field, an approach that author and award-winning Professor Robert Garland considers questionable.In these 36 passionate lectures, he provides an impressive and rare opportunity to understand the two dominant cultures of the ancient Mediterranean world in relation to one another - a relationship that has virtually no parallel in world history. He shows you how these two very different cultures intersected, coincided, and at times, collided.You'll discover the extraordinary culture that we call Greco-Roman: a unique fusion of civilizations that encompasses statecraft, mythology, language, philosophy, fine arts, architecture, science, and much else. Who were the Greeks and the Romans? How did they organize their societies? How did they interact?In this unique integrated historical approach, you'll see how Greece and Rome's relationship resembled a marriage: two distinct personalities competing in some areas, sharing in others, and sometimes creating a new synthesis of the two civilizations. And you'll consider their more substantive cultural differences, including religion, their views of foreigners, and their ways of thinking.You'll delight in the variety of sources - literature, archaeology, the visual arts, coinage, inscriptions - that Professor Garland draws upon to assemble a fascinating and complex picture of these two great civilizations. And you'll appreciate how he keeps Greece and Rome focused on how this material affects us today.
