How can matter behave both like a particle and a wave? Does a particle exist before we look at it or does the very act of looking bring it into reality? Is there a place where the quantum world ends and our perceivable world begins? Many of science's greatest minds including Thomas Young, Albert Einstein and Richard Feynman have grappled with the questions embodied in the simple yet elusive 'double-slit' experiment in order to understand the fabric of our universe. With his extraordinary gift for making the complicated comprehensible, Anil Ananthaswamy travels around the world and through history, down to the smallest scales of physical reality we have yet fathomed, to reveal the answers.

A scientific and globetrotting exploration of the physics experiments changing the ways we understand our universe. Why is the universe expanding? What is the nature of dark matter? Do other universes exist? In this timely and original book, science writer Anil Ananthaswamy embarks on a global journey to some of the world's most inhospitable and dramatic research sites to witness first-hand the audacious physics experiments conducted to answer profound questions about the nature of the universe. From the Atacama Desert in the Chilean Andes to the European Southern Observatory's Very Large Telescope on Mount Paranal to deep inside an abandoned iron mine in Minnesota and to the East Antarctic Ice Sheet, Ananthaswamy weaves together stories about the people and places at the heart of this cosmological research. While explaining the immense questions that scientists are trying to answer, Ananthaswamy provides an accessible and unique portrait of the universe and our quest to understand it. An atmospheric, engaging and illuminating read, The Edge of Physics depicts science as a human process and brings cosmology with all its rarefied concepts down to earth. ***PRAISE FOR THE EDGE OF PHYSICS*** 'A travelogue that celebrates the blood, sweat and tears that drive our understanding of the universe.' Guardian 'An excellent book. The author has a great knack of making difficult subjects comprehensible. I thoroughly enjoyed it.' Sir Patrick Moore 'A remarkable narrative that combines fundamental physics with high adventure.' New Scientist 'The ultimate physics-adventure travelogue... brilliant.' Physics World 'A grand tour of modern day cosmology's sacred places... evocative... engaging... refreshing... a taste of science in the heroic mode.'

Reveals the mind boggling neuroscience connecting brain, body, mind, and society, by examining a range of brain disorders, in the tradition of Oliver Sacks. Identifying what makes up the nature of the human mind has long been neuroscience's greatest challenge - a mystery perhaps never to be fully understood. Award-winning author and master of science journalism Anil Ananthaswamy smartly explores the concept of self by way of several mental conditions that alter patients' identities, showing how we learn a lot about being human from people with a fragmented or altered sense of self. He travels the world to meet those who suffer from "maladies of the self" interviewing patients, psychiatrists, philosophers and neuroscientists along the way. He charts how the self is affected by Asperger's, autism, Alzheimer's, epilepsy, schizophrenia, among many other mental conditions, revealing how the brain constructs our sense of self. Each chapter is anchored with stories of people who experience themselves differently from the norm. The Man Who Wasn't There is a magical mystery tour of scientific analysis and philosophical pondering, now utterly transformed by recent advances in cutting-edge neuroscience. ***PRAISE FOR THE MAN WHO WASN'T THERE*** 'Ananthaswamy excels at making theoretical concepts and experimental procedures both comprehensible and compelling.' Science 'If you simply want to read a great science book, I can't recommend any more highly than this one.' Forbes 'A compelling and entertaining look at the last untapped mystery, the true final frontier: the nature of our selves. Science journalism at its best.' Daniel J. Levitin, author of The Organized Mind 'An agreeably written travelogue through this mysterious landscape at the frontiers of knowledge.' The Wall Street Journal 'You'll never see yourself-or others-the same way again.' People 'Ananthaswamy's remarkable achievement is to make sense of these unhappy individuals' otherness, while holding on to their human sameness. You'll come away enlightened and chastened, asking searching questions about who you are.' Nicholas Humphrey, author of A History of the Mind 'It is an astonishing journey and an ambitious book, bringing together cutting-edge science and philosophy from West and East. You will not be quite the same self after reading it.' New Scientist

An Oliver Sacks-style tour of the neuroscience of schizophrenia, autism, Alzheimer's, epilepsy, Cotard's syndrome and out of body experiences in which people lose some critical sense of themselves - with sometimes bizarre and often painful results - revealing the absolute importance of our sense of self, however fragile and its nurture.Understanding "the self" has long been thought to be neuroscience's greatest challenge, a mystery perhaps that never can be solved. We are who we are - but mystics, Buddhists and even scientists have told us the self is an illusion. We know who we are but then no matter how successful and healthy you are, sometimes we wonder - who is that inside our heads? Who am I really? Are you sure you know? With the explosion of progress in the scientific investigation of conditions such as schizophrenia, autism, Alzheimer's, ecstatic epilepsy and Cotard's syndrome, as well as out of body experiences and Asperger's, we are learning about the Self at a level of detail that Descartes ("I think therefore I am") could never have imagined. Is the Self merely your ongoing autobiography, your personal narrative, as Antonio Damasio has suggested? Alzheimer's disease is illuminating the role of memory in the construction of that narrative as Ananthaswamy shows. The same part of your brain that remembers your life story is constructing your future life story. Is the location of the Self in our grey matter at hand? Those afflicted with Cotard's syndrome think they are already dead - in a way, they believe that "I think therefore I am not". But who - or what - is saying that? Neuroscience has identified specific regions of the brain that, when they misfire, can lead to the self can moving back and forth between the body and a doppelganger or leaving the body entirely and able to witness it's former body. But, then, where in the brain is the self actually located? As Ananthaswamy elegantly reports, neuroscientists themselves ultimately acknowledge that the self is both everywhere and nowhere in the brain's anatomy. Here is a magical mystery tour of one of the most ancient mysteries now utterly transformed by cutting edge neuroscience told by a master of science journalism.

In this deeply original book, science writer Anil Ananthaswamy sets out in search of the telescopes and detectors that promise to answer the biggest questions in modern cosmology. Why is the universe expanding at an ever faster rate? What is the nature of the "dark matter" that makes up almost a quarter of the universe? Why does the universe appear fine-tuned for life? Are there others besides our own?

Ananthaswamy soon finds himself at the ends of the earth--in remote and sometimes dangerous places. Take the Atacama Desert in the Chilean Andes, one of the coldest, driest places on the planet, where not even a blade of grass can survive. Its spectacularly clear skies and dry atmosphere allow astronomers to gather brilliant images of galaxies billions of light-years away. Ananthaswamy takes us inside the European Southern Observatory's Very Large Telescope on Mount Paranal, where four massive domes open to the sky each night "like dragons waking up."

He also takes us deep inside an abandoned iron mine in Minnesota, where half-mile-thick rock shields physicists as they hunt for elusive dark matter particles. And to the East Antarctic Ice Sheet, where engineers are drilling 1.5 miles into the clearest ice on the planet. They're building the world's largest neutrino detector, which could finally help reconcile quantum physics with Einstein's theory of general relativity.

The stories of the people who work at these and other dramatic research sites--from Lake Baikal in Siberia to the Indian Astronomical Observatory in the Himalayas to the subterranean lair of the Large Hadron Collider--make for a compelling new portrait of the universe and our quest to understand it. An atmospheric, engaging, and illuminating read, "The Edge of Physics" depicts science as a human process, bringing cosmology back down to earth in the most vivid terms.
