From number one New York Times bestselling author Michael Pollan, a radical challenge to how we think about drugs, and an exploration into the powerful human attraction to psychoactive plants--and the equally powerful taboos Of all the things humans rely on plants for--sustenance, beauty, medicine, fragrance, flavor, fiber--surely the most curious is our use of them to change consciousness: to stimulate or calm, fiddle with or completely alter, the qualities of our mental experience. Take coffee and tea: People around the world rely on caffeine to sharpen their minds. But we do not usually think of caffeine as a drug, or our daily use as an addiction, because it is legal and socially acceptable. So, then, what is a "drug"? And why, for example, is making tea from the leaves of a tea plant acceptable, but making tea from a seed head of an opium poppy a federal crime? In This Is Your Mind on Plants , Michael Pollan dives deep into three plant drugs--opium, caffeine, and mescaline--and throws the fundamental strangeness, and arbitrariness, of our thinking about them into sharp relief. Exploring and participating in the cultures that have grown up around these drugs while consuming (or, in the case of caffeine, trying not to consume) them, Pollan reckons with the powerful human attraction to psychoactive plants. Why do we go to such great lengths to seek these shifts in consciousness, and then why do we fence that universal desire with laws and customs and fraught feelings? In this unique blend of history, science, and memoir, as well as participatory journalism, Pollan examines and experiences these plants from several very different angles and contexts, and shines a fresh light on a subject that is all too often treated reductively--as a drug, whether licit or illicit. But that is one of the least interesting things you can say about these plants, Pollan shows, for when we take them into our bodies and let them change our minds, we are engaging with nature in one of the most profound ways we can. Based in part on an essay published almost twenty-five years ago, this groundbreaking and singular consideration of psychoactive plants, and our attraction to them through time, holds up a mirror to our fundamental human needs and aspirations, the operations of our minds, and our entanglement with the natural world.

*A New York Times Editors' Choice Pick* An "ambitious work" ( Washington Post ) tracing the links between autism and ingenuity Is the ability to invent things unique to humans? In The Pattern Seekers , Cambridge University psychologist Simon Baron-Cohen argues that it is, and proposes that autistic people have played a key role in human progress for seventy to one hundred thousand years, from the first complex tools like the bow and arrow and the first musical instrument to the digital revolution. He presents the science that the same genes that contribute to autism enable a special kind of pattern seeking that is essential to our species' inventiveness. However, these abilities come at a cost for autistic people, including social and neurological challenges. Baron-Cohen calls on us to support and celebrate autistic people in both their disabilities and their talents. Ultimately, The Pattern Seekers isn't just a new theory of human evolution, but a call to reconsider how society treats those who think differently.

From the bestselling author of Gratitude and Musicophilia , a collection of essays that displays Oliver Sacks's passionate engagement with the most compelling ideas of human endeavor: evolution, creativity, memory, time, consciousness, and experience. Oliver Sacks, scientist and storyteller, is beloved by readers for the extraordinary neurological case histories ( Awakenings , An Anthropologist on Mars ) in which he explored many now-familiar disorders--autism, Tourette syndrome, face blindness. He was also a memoirist who wrote with honesty and humor about the remarkable experiences that shaped him ( Uncle Tungsten , On the Move , Gratitude ). In the pieces that comprise The River of Consciousness (many first published in The New York Review of Books , among other places), Dr. Sacks takes on evolution, botany, chemistry, medicine, neuroscience, and the arts, and calls upon his great scientific and creative heroes--above all, Darwin, Freud, and William James. For Sacks, these thinkers were constant companions from an early age. The questions they explored--the meaning of evolution, the roots of creativity, and the nature of consciousness--lie at the heart of science and of this book. The River of Consciousness demonstrates Sacks's unparalleled ability to make unexpected connections, his sheer joy in knowledge, and his unceasing, timeless endeavor to understand what makes us human.

Rapid advances in the physical and biological sciences and in related technologies have brought about equally farreaching changes in mathematical research. Focusing on control theory, invariant imbedding, dynamic programming, and quasilinearization, Mr. Bellman explores with ease and clarity the mathematical research problems arising from scientific questions in engineering, physics, biology, and medicine. Special attention is paid in these essays to the use of the digital computer in obtaining the numerical solution of numerical problems, its influence in the formulation of new and old scientific problems in new terms, and to some of the effects of the computer revolution on educational and social systems. The new opportunities for mathematical research presage, Bellman concludes, a renaissance of mathematics in human affairs by involving it closely in the problems of society.
