Other Minds: The Octopus, the Sea, and the Deep Origins of Consciousness
Peter Godfrey-Smith - 2016
In captivity, octopuses have been known to identify individual human keepers, raid neighboring tanks for food, turn off lightbulbs by spouting jets of water, plug drains, and make daring escapes. How is it that a creature with such gifts evolved through an evolutionary lineage so radically distant from our own? What does it mean that evolution built minds not once but at least twice? The octopus is the closest we will come to meeting an intelligent alien. What can we learn from the encounter?In Other Minds, Peter Godfrey-Smith, a distinguished philosopher of science and a skilled scuba diver, tells a bold new story of how subjective experience crept into being—how nature became aware of itself. As Godfrey-Smith stresses, it is a story that largely occurs in the ocean, where animals first appeared. Tracking the mind’s fitful development, Godfrey-Smith shows how unruly clumps of seaborne cells began living together and became capable of sensing, acting, and signaling. As these primitive organisms became more entangled with others, they grew more complicated. The first nervous systems evolved, probably in ancient relatives of jellyfish; later on, the cephalopods, which began as inconspicuous mollusks, abandoned their shells and rose above the ocean floor, searching for prey and acquiring the greater intelligence needed to do so. Taking an independent route, mammals and birds later began their own evolutionary journeys.But what kind of intelligence do cephalopods possess? Drawing on the latest scientific research and his own scuba-diving adventures, Godfrey-Smith probes the many mysteries that surround the lineage. How did the octopus, a solitary creature with little social life, become so smart? What is it like to have eight tentacles that are so packed with neurons that they virtually “think for themselves”? What happens when some octopuses abandon their hermit-like ways and congregate, as they do in a unique location off the coast of Australia?By tracing the question of inner life back to its roots and comparing human beings with our most remarkable animal relatives, Godfrey-Smith casts crucial new light on the octopus mind—and on our own.
How to Argue With a Racist: What Our Genes Do (and Don't) Say About Human Difference
Adam Rutherford - 2020
But its toxic effects on society are plain to see—feeding white nationalism, fueling hatred, endangering lives, and corroding our discourse on everything from sports to intelligence. Even well-intentioned people repeat stereotypes based on “science,” because cutting-edge genetics are hard to grasp—and all too easy to distort. Paradoxically, these misconceptions are multiplying even as scientists make unprecedented discoveries in human genetics—findings that, when accurately understood, are powerful evidence against racism. We’ve never had clearer answers about who we are and where we come from, but this knowledge is sorely needed in our casual conversations about race.How to Argue With a Racist emphatically dismantles outdated notions of race by illuminating what modern genetics actually can and can’t tell us about human difference. We now know that the racial categories still dividing us do not align with observable genetic differences. In fact, our differences are so minute that, most of all, they serve as evidence of our shared humanity.
How Not to Be Wrong: The Power of Mathematical Thinking
Jordan Ellenberg - 2014
In How Not to Be Wrong, Jordan Ellenberg shows us how terribly limiting this view is: Math isn’t confined to abstract incidents that never occur in real life, but rather touches everything we do—the whole world is shot through with it.Math allows us to see the hidden structures underneath the messy and chaotic surface of our world. It’s a science of not being wrong, hammered out by centuries of hard work and argument. Armed with the tools of mathematics, we can see through to the true meaning of information we take for granted: How early should you get to the airport? What does “public opinion” really represent? Why do tall parents have shorter children? Who really won Florida in 2000? And how likely are you, really, to develop cancer?How Not to Be Wrong presents the surprising revelations behind all of these questions and many more, using the mathematician’s method of analyzing life and exposing the hard-won insights of the academic community to the layman—minus the jargon. Ellenberg chases mathematical threads through a vast range of time and space, from the everyday to the cosmic, encountering, among other things, baseball, Reaganomics, daring lottery schemes, Voltaire, the replicability crisis in psychology, Italian Renaissance painting, artificial languages, the development of non-Euclidean geometry, the coming obesity apocalypse, Antonin Scalia’s views on crime and punishment, the psychology of slime molds, what Facebook can and can’t figure out about you, and the existence of God.Ellenberg pulls from history as well as from the latest theoretical developments to provide those not trained in math with the knowledge they need. Math, as Ellenberg says, is “an atomic-powered prosthesis that you attach to your common sense, vastly multiplying its reach and strength.” With the tools of mathematics in hand, you can understand the world in a deeper, more meaningful way. How Not to Be Wrong will show you how.
Lifespan: Why We Age—and Why We Don't Have To
David A. Sinclair - 2019
But what if everything we’ve been taught to believe about aging is wrong? What if we could choose our lifespan? In this groundbreaking book, Dr. David Sinclair, leading world authority on genetics and longevity, reveals a bold new theory for why we age. As he writes: “Aging is a disease, and that disease is treatable.” This book takes us to the frontlines of research many from Dr. David Sinclair’s own lab at Harvard—that demonstrate how we can slow down, or even reverse, aging. The key is activating newly discovered vitality genes, the descendants of an ancient genetic survival circuit that is both the cause of aging and the key to reversing it.
The Defining Decade: Why Your Twenties Matter—And How to Make the Most of Them Now
Meg Jay - 2012
Some say they are an extended adolescence. Others call them an emerging adulthood. But thirty is not the new twenty. In this enlightening book, Dr. Meg Jay reveals how many twentysomethings have been caught in a swirl of hype and misinformation that has trivialized what are actually the most defining years of adulthood. Drawing from more than ten years of work with hundreds of twentysomething clients and students, Dr. Jay weaves the science of the twentysomething years with compelling, behind-closed-doors stories from twentysomethings themselves. She shares what psychologists, sociologists, neurologists, reproductive specialists, human resources executives, and economists know about the unique power of our twenties and how they change our lives. The result is a provocative and sometimes poignant read that shows us why our twenties do matter. Our twenties are a time when the things we do--and the things we don't do--will have an enormous effect across years and even generations to come.
Nightfall
Isaac Asimov - 1990
The story was called "Nightfall", and many years later it has long been recognized as a classic, its author a legend. Now, the Gran Master of Science Fiction teams with Robert Silverberg, one of the field's top award-winning authors, to explore and expand an apocalyptic tale that is more spellbinding today than ever before -- Nightfall: The Novel.Imagine living on a planet with six suns that never experiences Darkness. Imagine never having seen the Stars. Then, one by one the suns start to set, gradually leading into Darkness for the first time ever. Kalgash is a world on the edge of chaos, torn between the madness of religious fanaticism and the unyielding rationalism of scientists. Lurking beneath it all is a collective, instinctual fear of the Darkness. For Kalgash knows only the perpetual light of day; to its inhabitants, a gathering twilight portends unspeakable horror. And only a handful of people on the planet are prepared to face the truth, their six suns are setting all at once for the first time in over two thousand years, signaling the end of civilization as it explodes in the awesome splendor of Nightfall.Encompassing the psychology of disaster, the tenacity of the human spirit, and, ultimately, the regenerative power of hope, Nightfall is a tale rich in character and suspense that only the unique collaboration of Isaac Asimov and Robert Silverberg could create.
The Invention of Science: The Scientific Revolution from 1500 to 1750
David Wootton - 2015
Yet today, science and its practitioners have come under political attack. In this fascinating history spanning continents and centuries, historian David Wootton offers a lively defense of science, revealing why the Scientific Revolution was truly the greatest event in our history.The Invention of Science goes back five hundred years in time to chronicle this crucial transformation, exploring the factors that led to its birth and the people who made it happen. Wootton argues that the Scientific Revolution was actually five separate yet concurrent events that developed independently, but came to intersect and create a new worldview. Here are the brilliant iconoclasts—Galileo, Copernicus, Brahe, Newton, and many more curious minds from across Europe—whose studies of the natural world challenged centuries of religious orthodoxy and ingrained superstition.From gunpowder technology, the discovery of the new world, movable type printing, perspective painting, and the telescope to the practice of conducting experiments, the laws of nature, and the concept of the fact, Wotton shows how these discoveries codified into a social construct and a system of knowledge. Ultimately, he makes clear the link between scientific discovery and the rise of industrialization—and the birth of the modern world we know.

Strange New Worlds: The Search for Alien Planets and Life Beyond Our Solar System
Ray Jayawardhana - 2011
Before the decade is out, telltale signs that they harbor life may be found. If they are, the ramifications for all areas of human thought and endeavor--from religion and philosophy to art and biology--will be breathtaking. In Strange New Worlds, renowned astronomer Ray Jayawardhana brings news from the front lines of the epic quest to find planets--and alien life--beyond our solar system.Only in the past fifteen years, after millennia of speculation, have astronomers begun to discover planets around other stars--hundreds in fact. But the hunt to find a true Earth-like world goes on. In this book, Jayawardhana vividly recounts the stories of the scientists and the remarkable breakthroughs that have ushered in this extraordinary age of exploration. He describes the latest findings--including his own--that are challenging our view of the cosmos and casting new light on the origins and evolution of planets and planetary systems. He reveals how technology is rapidly advancing to support direct observations of Jupiter-like gas giants and super-Earths--rocky planets with several times the mass of our own planet--and how astronomers use biomarkers to seek possible life on other worlds.Strange New Worlds provides an insider's look at the cutting-edge science of today's planet hunters, our prospects for discovering alien life, and the debates and controversies at the forefront of extrasolar-planet research.
Disturbing the Universe
Freeman Dyson - 1979

Light
M. John Harrison - 2002
John Harrison’s dangerously illuminating new novel, three quantum outlaws face a universe of their own creation, a universe where you make up the rules as you go along and break them just as fast, where there’s only one thing more mysterious than darkness.In contemporary London, Michael Kearney is a serial killer on the run from the entity that drives him to kill. He is seeking escape in a future that doesn’t yet exist—a quantum world that he and his physicist partner hope to access through a breach of time and space itself. In this future, Seria Mau Genlicher has already sacrificed her body to merge into the systems of her starship, the White Cat. But the “inhuman” K-ship captain has gone rogue, pirating the galaxy while playing cat and mouse with the authorities who made her what she is. In this future, Ed Chianese, a drifter and adventurer, has ridden dynaflow ships, run old alien mazes, surfed stellar envelopes. He “went deep”—and lived to tell about it. Once crazy for life, he’s now just a twink on New Venusport, addicted to the bizarre alternate realities found in the tanks—and in debt to all the wrong people.Haunting them all through this maze of menace and mystery is the shadowy presence of the Shrander—and three enigmatic clues left on the barren surface of an asteroid under an ocean of light known as the Kefahuchi Tract: a deserted spaceship, a pair of bone dice, and a human skeleton.
Tomorrowland: Our Staggering Journey from Science Fiction to Science Fact
Steven Kotler - 2015
Now he gathers the best of his best, updated and expanded upon, to guide readers on a mind-bending tour of the far frontier, and how these advances are radically transforming our lives. From the ways science and technology are fundamentally altering our bodies and our world (the world’s first bionic soldier, the future of evolution) to those explosive collisions between science and culture (life extension and bioweapons), we’re crossing moral and ethical lines we’ve never faced before.As Kotler writes, “Life is tricky sport—and that's the emotional core of this story, the real reason we can’t put Pandora back in the box. When you strip everything else away, technology is nothing more than the promise of an easier tomorrow. It’s the promise of hope. And how do you stop hope?”Join Kotler in this fascinating exploration of our incredible next: a deep dive into those future technologies happening now—and what it means to be a part of this brave new world.
Old Man's War
John Scalzi - 2005
First he visited his wife's grave. Then he joined the army.The good news is that humanity finally made it into interstellar space. The bad news is that planets fit to live on are scarce-- and alien races willing to fight us for them are common. So: we fight. To defend Earth, and to stake our own claim to planetary real estate. Far from Earth, the war has been going on for decades: brutal, bloody, unyielding.Earth itself is a backwater. The bulk of humanity's resources are in the hands of the Colonial Defense Force. Everybody knows that when you reach retirement age, you can join the CDF. They don't want young people; they want people who carry the knowledge and skills of decades of living. You'll be taken off Earth and never allowed to return. You'll serve two years at the front. And if you survive, you'll be given a generous homestead stake of your own, on one of our hard-won colony planets.John Perry is taking that deal. He has only the vaguest idea what to expect. Because the actual fight, light-years from home, is far, far harder than he can imagine--and what he will become is far stranger.
How We'll Live on Mars
Stephen L. Petranek - 2014
Now he makes the case that living on Mars is not just plausible, but inevitable.It sounds like science fiction, but Stephen Petranek considers it fact: Within twenty years, humans will live on Mars. We'll need to. In this sweeping, provocative book that mixes business, science, and human reporting, Petranek makes the case that living on Mars is an essential back-up plan for humanity and explains in fascinating detail just how it will happen.The race is on. Private companies, driven by iconoclastic entrepreneurs, such as Elon Musk, Jeff Bezos, Paul Allen, and Sir Richard Branson; Dutch reality show and space mission Mars One; NASA; and the Chinese government are among the many groups competing to plant the first stake on Mars and open the door for human habitation. Why go to Mars? Life on Mars has potential life-saving possibilities for everyone on earth. Depleting water supplies, overwhelming climate change, and a host of other disasters — from terrorist attacks to meteor strikes — all loom large. We must become a space-faring species to survive. We have the technology not only to get humans to Mars, but to convert Mars into another habitable planet. It will likely take 300 years to "terraform" Mars, as the jargon goes, but we can turn it into a veritable second Garden of Eden. And we can live there, in specially designed habitations, within the next twenty years.In this exciting chronicle, Petranek introduces the circus of lively characters all engaged in a dramatic effort to be the first to settle the Red Planet. How We'll Live on Mars brings firsthand reporting, interviews with key participants, and extensive research to bear on the question of how we can expect to see life on Mars within the next twenty years.
