How much can we know about the world? In this audiobook physicist Marcelo Gleiser traces our search for answers to the most fundamental questions of existence, the origin of the universe, the nature of reality, and the limits of knowledge. In so doing he reaches a provocative conclusion: Science, like religion, is fundamentally limited as a tool for understanding the world. As science and its philosophical interpretations advance, we face the unsettling recognition of how much we don't know.

In a blossoming garden located far outside all worlds, a group of aging Greek gods have gathered to discuss the nature of existence, the mystery of mind, and whether there is a transcendent God from whom all things come. Turning to Eros, Psyche asks, "Do you see this flower, my love?"

In The Secrets of Alchemy, Lawrence M. Principe, one of the world's leading authorities on the subject, brings alchemy out of the shadows and restores it to its important place in human history and culture. By surveying what alchemy was and how it began, developed, and overlapped with a range of ideas and pursuits, Principe illuminates the practice. He vividly depicts the place of alchemy during its heyday in early modern Europe, and then explores how alchemy has fit into wider views of the cosmos and humanity.

Today’s technology has overtaken religion as the chief influence on twenty-first century life and community.

Can beliefs make you sick? Consider "The June Bug" incident from a US textile factory in the early 1960s. Many employees began to feel dizzy, had an upset stomach, and vomited. Some were even hospitalized. The illness was attributed to a mysterious bug biting workers. However, when the CDC investigated this outbreak, no bugs or any other cause of the illnesses could be identified. Instead, it appears to be an illness caused by the mind -- that is, sickness due to expectation.

Conjectures and Refutations is one of Karl Popper’s most wide-ranging and popular works, notable not only for its acute insights into the way scientific knowledge grows, but also for applying those insights to politics and to history. It provides one of the clearest and most accessible statements of the fundamental idea that guided his work: not only our knowledge but our aims and our standards grow through an unending process of trial and error.

Americans hold marriage in such high esteem that we push people toward it, reward them for taking part in it, and fetishize its benefits to the point that we routinely ignore or excuse bad behavior and societal ills in the name of protecting and promoting it. Through revealing storytelling, Zug builds a compelling case that when marriage is touted as “the solution” to such problems, it absolves the government, and society, of the responsibility for directly addressing them.

Humans have long thought of their bodies and minds as separate spheres of existence. The body is physical. But the mind is mental; it perceives, remembers, believes, feels, and imagines. Although modern science has largely eliminated this mind-body dualism, people still tend to imagine their minds as separate from their physical being. Even in research, the notion of the "self" as somehow distinct from the rest of the organism persists. Joseph LeDoux argues that we have hit an epistemological wall—that ideas like the self are increasingly barriers to discovery and understanding.

In Waves in an Impossible Sea, physicist Matt Strassler tells a startling tale of elementary particles, human experience, and empty space. He begins with a simple mystery of motion. When we drive at highway speeds with the windows down, the wind beats against our faces. Yet our planet hurtles through the cosmos at 150 miles per second, and we feel nothing of it. How can our voyage be so tranquil when, as Einstein discovered, matter warps space, and space deflects matter? The answer, Strassler reveals, is that empty space is a sea, albeit a paradoxically strange one.

It is rare for life to change Earth, yet three organisms have profoundly transformed our planet over the long course of its history. Elemental reveals how microbes, plants, and people used the fundamental building blocks of life to alter the climate, and with it, the trajectory of life on Earth in the past, present, and future. Taking listeners from the deep geologic past to our current era of human dominance, Stephen Porder focuses on five of life’s essential elements—hydrogen, oxygen, carbon, nitrogen, and phosphorus.

Called "a world-class power broker" by the Washington Post, Robert Brown has been a sought-after counselor for an impressive array of the famous and powerful, including every American president since John F. Kennedy. But as a child born into poverty in the 1930s, Robert was raised by his grandmother to think differently about success. For example, "The best way to influence others is to be helpful", she told him. And, "You can’t go wrong by doing right." Fueled by these lessons, Brown went on to play a pivotal, mostly unseen role alongside the powerful of our time.

For most of history, humans did without refined sugar. Granulated sugar was first produced in India around the sixth century BC, yet for almost 2,500 years afterward sugar remained marginal in the diets of most people. Then, suddenly, it was everywhere. How did sugar find its way into almost all the food we eat, fostering illness and ecological crisis along the way? The World of Sugar begins with the earliest evidence of sugar production.

For centuries, people have been returning to the same tired nature-versus-nurture debate, trying to determine what we learn and what we inherit. In Dancing Cockatoos and the Dead Man Test, biologist Marlene Zuk goes beyond the binary and instead focuses on interaction, or the way that genes and environment work together. Driving her investigation is a simple but essential question: How does behavior evolve?

The period from 1933 to 1943 was one of the darkest and most chaotic in human history, as the Second World War unfolded with unthinkable cruelty. It was also a crucial decade in the dramatic, intersecting lives of some of history’s greatest philosophers.
