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.

At a time when the very foundations of American democracy seem under threat, the lessons of the past offer a road map for navigating a moment of political crisis. In Democracy Awakening, acclaimed historian Heather Cox Richardson delves into the tumultuous journey of American democracy, tracing the roots of Donald Trump’s “authoritarian experiment” to the earliest days of the republic.

Inspired by her research for the hit podcast Ultra, Rachel Maddow charts the rise of a wild American strain of authoritarianism that has been alive on the far-right edge of our politics for the better part of a century. Before and even after our troops had begun fighting abroad in World War II, a clandestine network flooded the country with disinformation aimed at sapping the strength of the U.S. war effort and persuading Americans that our natural alliance was with the Axis, not against it.

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.

For much of history, societies have violently oppressed ethnic, religious, and sexual minorities. It is no surprise that many who passionately believe in social justice came to believe that members of marginalized groups need to take pride in their identity to resist injustice.

What if you woke up one morning and found you’d acquired another self—a double who was almost you and yet not you at all? What if that double shared many of your preoccupations but, in a twisted, upside-down way, furthered the very causes you’d devoted your life to fighting against? Not long ago, the celebrated activist and public intellectual Naomi Klein had just such an experience—she was confronted with a doppelganger whose views she found abhorrent but whose name and public persona were sufficiently similar to her own that many people got confused about who was who.

We feel, therefore we are. Conscious sensations ground our sense of self. They are crucial to our idea of ourselves as psychic beings: present, existent, and mattering. But is it only humans who feel this way? Do other animals? Will future machines? Weaving together intellectual adventure and cutting-edge science, Nicholas Humphrey describes in Sentience his quest for answers: from his discovery of blindsight in monkeys and his pioneering work on social intelligence to breakthroughs in the philosophy of mind.

Gazing at the stars, falling in love, or listening to music, we sometimes feel a transcendent connection with a cosmic unity and things larger than ourselves. But these experiences are not easily understood by science, which holds that all things can be explained in terms of atoms and molecules. Is there space in our scientific worldview for these spiritual experiences?

The conditions that allowed humans to live on this earth are fragile, incredibly so. Climate variability has at times created new niches that humans or their ancestors could potentially exploit, and challenges that at times have spurred innovation. But there’s a relatively narrow envelope of climate variability within which human civilization remains viable. And our survival depends on conditions remaining within that range. In this book, renowned climate scientist Michael Mann will arm listeners with the knowledge necessary to appreciate the gravity of the unfolding climate crisis.

Everyone is curious about life in the Universe, UFOs and whether ET is out there. Over the course of his thirty-year career as an astrophysicist, Adam Frank has consistently been asked about the possibility of intelligent life in the universe. Are aliens real? Where are they? Why haven’t we found them? What happens if we do?

Over the past two generations, U.S. leaders deregulated big business on the faith that it would yield a better economy and a freer society. But the opposite happened. Americans lost stable, well-paying jobs, Wall Street dominated industry to the detriment of the middle class and local communities, and corporations began to subject us to total surveillance, even dictating what we are, and aren’t, allowed to think. The corporate titans and mega-donors who aligned themselves with this vision knew exactly what they were getting: perfect conditions for what Sohrab Ahmari calls “private tyranny”.

In lyric, accessible prose, Carlo Rovelli invites us to consider questions about the nature of time that continue to puzzle physicists and philosophers alike. For most listeners, this is unfamiliar terrain. We all experience time, but the more scientists learn about it, the more mysterious it appears. We think of it as uniform and universal, moving steadily from past to future, measured by clocks. Rovelli tears down these assumptions one by one, revealing a strange universe where, at the most fundamental level, time disappears.

Inflammation is the body’s ancestral response to its greatest threats: injury and foreign microbes. But as the threats we face have evolved, new science reveals simmering inflammation underneath the surface of everything from heart disease and cancer to mysterious autoimmune conditions. In A Silent Fire, gastroenterologist Shilpa Ravella takes us on a lyrical quest across time, around the world, and into the body to reveal hidden inflammation at the root of modern disease―and how we can control it.

An energizing case for hope about the climate comes from Rebecca Solnit, called “the voice of the resistance” by the New York Times, and climate activist Thelma Young Lutunatabua, along with a chorus of voices calling on us to rise to the moment. Not Too Late is the book for anyone who is despondent, defeatist, or unsure about climate change and seeking answers. As the contributors to this volume make clear, the future will be decided by whether we act in the present—and we must act to counter institutional inertia, fossil fuel interests, and political obduracy.

Cosmos is one of the bestselling science books of all time. In clear-eyed prose, Sagan reveals a jewel-like blue world inhabited by a life form that is just beginning to discover its own identity and to venture into the vast ocean of space.

Until the End of Time is Brian Greene's breathtaking new exploration of the cosmos and our quest to find meaning in the face of this vast expanse. Greene takes us on a journey from the big bang to the end of time, exploring how lasting structures formed, how life and mind emerged, and how we grapple with our existence through narrative, myth, religion, creative expression, science, the quest for truth, and a deep longing for the eternal.

A breakout best seller in Italy, now available for American listeners for the first time, Genesis: The Story of How Everything Began is a short, humanistic tour of the origins of the universe, earth, and life - drawing on the latest discoveries in physics to explain the seven most significant moments in the creation of the cosmos.

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.

The Big Bang is all but dead, and we do not yet know what will replace it. Our universe's "beginning" is at an end. What does this have to do with us here on Earth? Our lives are about to be dramatically shaken again - as altered as they were with the invention of the clock, the steam engine, the railroad, the radio and the Internet.

Since its 2009 launch, the Kepler satellite has discovered more than 2,000 exoplanets, or planets outside our solar system. More exoplanets are being discovered all the time, remarkable in their variety. Astronomer Michael Summers and physicist James Trefil explore these remarkable recent discoveries: planets revolving around pulsars, planets made of diamond, planets that are mostly water, and numerous rogue planets wandering through the emptiness of space.

The late great astronomer and astrophysicist describes his personal search to understand the nature of the sacred in the vastness of the cosmos. Exhibiting a breadth of intellect nothing short of astounding, Sagan presents his views on a wide range of topics, including the likelihood of intelligent life on other planets, creationism and so-called intelligent design.

Einstein’s revolutionary scientific ideas have transformed our world, ushering in the nuclear age. The current pace of scientific and technological progress is simply astounding. So is there any place for faith in such a world? Einstein himself gave careful thought to the deepest questions of life. His towering intellectual status means he is someone worth listening to when we think through the big questions of life.

In Beyond Biocentrism, acclaimed biologist Robert Lanza and astronomer Bob Berman take the listener on an intellectual thrill ride as they reexamine everything we thought we knew about life, death, the universe, and the nature of reality itself. The first step is acknowledging that our existing model of reality is looking increasingly creaky in the face of recent scientific discoveries.

Shining a light on the most profound insights revealed by modern physics, Jim Al-Khalili invites us all to understand what this crucially important science tells us about the universe and the nature of reality itself. Al-Khalili begins by introducing the fundamental concepts of space, time, energy, and matter, and then describes the three pillars of modern physics - quantum theory, relativity, and thermodynamics - showing how all three must come together if we are ever to have a full understanding of reality.

Professor Brian Cox uncovers some of the most extraordinary natural events on Earth and in the universe and beyond. From the immensity of the universe and the roundness of Earth to the form of every single snowflake, the forces of nature shape everything we see. Pushed to extremes, the results are astonishing. In seeking to understand the everyday world, the colours, structure, behaviour and history of our home, we develop the knowledge and techniques necessary to step beyond the everyday.

Humanity has reached a critical moment. Our world is unsettled and rapidly changing, and we face existential risks over the next century. Various outcomes - good and bad - are possible. Yet our approach to the future is characterized by short-term thinking, polarizing debates, alarmist rhetoric, and pessimism. In this short, exhilarating book, renowned scientist and best-selling author Martin Rees argues that humanity’s prospects depend on our taking a very different approach to planning for tomorrow.

When Matthieu Ricard and Trinh Thuan met at an academic conference in the summer of 1997, they began discussing the many remarkable connections between the teachings of Buddhism and the findings of recent science. That conversation grew into an astonishing correspondence exploring a series of fascinating questions. Did the universe have a beginning? Might our perception of time in fact be an illusion, a phenomenon created in our brains that has no ultimate reality? What is consciousness and how did it evolve?

For at least 20,000 years, we have led not just an earthly existence, but a cosmic one. Celestial cycles drove every aspect of our daily lives. Our innate relationship with the stars shaped who we are - our art, religious beliefs, social status, scientific advances, and even our biology. But over the last few centuries we have separated ourselves from the universe that surrounds us. It's a disconnect with a dire cost.

What is consciousness? Why are we here? Where did it all come from - the laws of nature, the stars, the universe? Humans have been asking these questions forever, but science hasn't succeeded in providing many answers - until now. In The Grand Biocentric Design, Robert Lanza, one of Time magazine's "100 Most Influential People", is joined by theoretical physicist Matej Pavšic and astronomer Bob Berman to shed light on the big picture that has long eluded philosophers and scientists alike.

Already internationally acclaimed for his elegant, lucid writing on the most challenging notions in modern physics, Sean Carroll is emerging as one of the greatest humanist thinkers of his generation as he brings his extraordinary intellect to bear not only on the Higgs boson and extra dimensions but now also on our deepest personal questions. Where are we? Who are we? Are our emotions, our beliefs, and our hopes and dreams ultimately meaningless out there in the void?
