Understanding our humanity - the essence of who we are - is one of the deepest mysteries and biggest challenges in modern science. Why do we have bad moods? Why are we capable of having such strange dreams? How can metaphors in our language hold such sway on our actions? As we learn more about the mechanisms of human behavior through evolutionary biology, neuroscience, anthropology, and other related fields, we're discovering just how intriguing the human species is.

Robert Sapolsky’s Behave, his now classic account of why humans do good and why they do bad, pointed toward an unsettling conclusion: We may not grasp the precise marriage of nature and nurture that creates the physics and chemistry at the base of human behavior, but that doesn’t mean it doesn’t exist. Now, in Determined, Sapolsky takes his argument all the way, mounting a brilliant (and in his inimitable way, delightful) full-frontal assault on the pleasant fantasy that there is some separate self telling our biology what to do.

From the celebrated neurobiologist and primatologist, a landmark, genre-defining examination of human behavior, both good and bad, and an answer to the question: Why do we do the things we do? 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.

In 24 thought-provoking lectures designed for nonscientists, this course explores today's exciting field of genomics, the study of the vast storehouse of information contained within chromosomes. Your professor is Princeton University biologist Lee M. Silver, an acclaimed teacher, scientist, and author of popular books on biotechnology, genetics, and their impact on society.

No skill is more important in today's world than being able to think about, understand, and act on information in an effective and responsible way. What's more, at no point in human history have we had access to so much information, with such relative ease, as we do in the 21st century. But because misinformation out there has increased as well, critical thinking is more important than ever. These 24 rewarding lectures equip you with the knowledge and techniques you need to become a savvier, sharper critical thinker in your professional and personal life.

Eating is an indispensable human activity. As a result, whether we realize it or not, the drive to obtain food has been a major catalyst across all of history, from prehistoric times to the present. Epicure Jean-Anthelme Brillat-Savarin said it best: "Gastronomy governs the whole life of man."

Now in a third edition, Robert M. Sapolsky's acclaimed and successful Why Zebras Don't Get Ulcers features new chapters on how stress affects sleep and addiction, as well as new insights into anxiety and personality disorder and the impact of spirituality on managing stress. As Sapolsky explains, most of us do not lie awake at night worrying about whether we have leprosy or malaria. Instead, the diseases we fear-and the ones that plague us now-are illnesses brought on by the slow accumulation of damage, such as heart disease and cancer.

Grasp the important ideas that have served as the backbone of philosophy across the ages with this extraordinary 60-lecture series. This is your opportunity to explore the enormous range of philosophical perspectives and ponder the most important and enduring of human questions-without spending your life poring over dense philosophical texts.

Conventional wisdom suggests there is a sharp distinction between emotion and reason. Emotions are seen as inferior, disruptive, primitive, and even bestial forces.

Charles Darwin's theory of organic evolution-the idea that life on earth is the product of purely natural causes, not the hand of God-set off shock waves that continue to reverberate through Western society, and especially the United States. What makes evolution such a profoundly provocative concept, so convincing to most scientists, yet so socially and politically divisive? These 12 eye-opening lectures are an examination of the varied elements that so often make this science the object of strong sentiments and heated debate.

Whether complete or only fragmentary, the 930 extant Dead Sea Scrolls irrevocably altered how we look at and understand the foundations of faith and religious practice. Now you can get a comprehensive introduction to this unique series of archaeological documents, and to scholars' evolving understanding of their authorship and significance, with these 24 lectures. Learn what the scrolls are, what they contain, and how the insights they offered into religious and ancient history came into focus.

Between 1861 and 1865, the clash of the greatest armies the Western hemisphere had ever seen turned small towns, little-known streams, and obscure meadows in the American countryside into names we will always remember. In those great battles, those streams ran red with blood-and the United States was truly born.

"It doesn't take an Einstein to understand modern physics," says Professor Wolfson at the outset of these 24 lectures on what may be the most important subjects in the universe: relativity and quantum physics. Both have reputations for complexity. But the basic ideas behind them are, in fact, simple and comprehensible by anyone. These dynamic and illuminating lectures begin with a brief overview of theories of physical reality starting with Aristotle and culminating in Newtonian or "classical" physics.

Richard Dawkins' brilliant reformulation of the theory of natural selection has the rare distinction of having provoked as much excitement and interest outside the scientific community as within it. His theories have helped change the whole nature of the study of social biology, and have forced thousands to rethink their beliefs about life.

Astrophysicist Neil deGrasse Tyson has attracted one of the world’s largest online followings with his fascinating, widely accessible insights into science and our universe. Now, Tyson invites us to go behind the scenes of his public fame by unveiling his candid correspondence with people across the globe who have sought him out in search of answers.

In The Butchering Art, the historian Lindsey Fitzharris reveals the shocking world of 19th-century surgery on the eve of profound transformation. She conjures up early operating theaters - no place for the squeamish - and surgeons, working before anesthesia, who were lauded for their speed and brute strength. They were baffled by the persistent infections that kept mortality rates stubbornly high. A young, melancholy Quaker surgeon named Joseph Lister would solve the deadly riddle and change the course of history.

Every day of your life is spent surrounded by mysteries that involve what appear to be rather ordinary human behaviors. What makes you happy? Where did your personality come from? Why do you have trouble controlling certain behaviors? Why do you behave differently as an adult than you did as an adolescent?Since the start of recorded history, and probably even before, people have been interested in answering questions about why we behave the way we do.

Bringing together the imaginative strategies of fiction storytelling and new ways of narrating true, real-life events, creative nonfiction is the fastest-growing part of the creative writing world. It's a cutting-edge genre that's reshaping how we write (and read) everything from biographies and memoirs to blogs and public speaking scripts to personal essays and magazine articles.

Can literature change our real world society? At its foundation, utopian and dystopian fiction asks a few seemingly simple questions aimed at doing just that. Who are we as a society? Who do we want to be? Who are we afraid we might become? When these questions are framed in the speculative versions of Heaven and Hell on earth, you won't find easy answers, but you will find tremendously insightful and often entertaining perspectives.

Look beyond the abstract dates and figures, kings and queens, and battles and wars that make up so many historical accounts. Over the course of 48 richly detailed lectures, Professor Garland covers the breadth and depth of human history from the perspective of the so-called ordinary people, from its earliest beginnings through the Middle Ages.
