| the edge of physics by anil ananthaswamy: Through Two Doors at Once Anil Ananthaswamy, 2020-01-23 The clearest, most accessible explanation yet of the amazing world of quantum mechanics. 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? Are there hidden elements to reality missing from the orthodox view of quantum physics? And is there a place where the quantum world ends and our perceivable world begins? Many of science's greatest minds have grappled with these questions embodied by the simple yet elusive double-slit experiment. Thomas Young devised it in the early 1800s to show that light behaves like a wave, and in doing so opposed Isaac Newton’s theories. Nearly a century later, Albert Einstein showed that light comes in particles, and the experiment became key to a fierce debate with Niels Bohr over the nature of reality. Richard Feynman held that the double slit embodies the central mystery of the quantum world. Hypothesis after hypothesis, scientists have returned to this ingenious experiment to help them answer the deep questions about 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 for the answers. ***PRAISE FOR THROUGH TWO DOORS AT ONCE*** A Physics Book of the Year A Forbes Best Book of the Year A Kirkus Best Book of the Year A Smithsonian Favourite Book of the Year Publisher's Weekly Best Books of Autumn 'A fascinating read and a must for anyone who would like to find out the latest experimental advances made in this most fundamental of quantum experiments.'

| the edge of physics by anil ananthaswamy: The Man Who Wasn’t There Anil Ananthaswamy, 2018-10-05 Anil Ananthaswamy offers an intimate look at the latest neuroscience of schizophrenia, autism, Alzheimer’s disease and Cotard’s syndrome, among others, to reveal the power of the human sense of self. Extensive in-depth interviews venture into the lives of individuals who offer remarkable and sometimes heart-wrenching insights. One man cut off his own leg. Another became one with the universe. Where in the brain, or mind, or body is the self actually located? As Ananthaswamy reports: neuroscientists now themselves see that the elusive sense of self is both everywhere and nowhere in the brain. The Man Who Wasn’t There takes readers on an emotional, scientific and intellectual journey, arriving at a new visceral understanding of something we have wondered about since humans existed. |
| the edge of physics by anil ananthaswamy: Strange Tools Alva Noë, 2015-09-22 A philosopher makes the case for thinking of works of art as tools for investigating ourselves. In Strange Tools: Art and Human Nature, the philosopher and cognitive scientist Alva Noë argues that our obsession with works of art has gotten in the way of understanding how art works on us. For Noë, art isn’t a phenomenon in need of an explanation but a mode of research, a method of investigating what makes us human—a strange tool. Art isn’t just something to look at or listen to—it is a challenge, a dare to try to make sense of what it is all about. Art aims not for satisfaction but for confrontation, intervention, and subversion. Through diverse and provocative examples from the history of art-making, Noë reveals the transformative power of artistic production. By staging a dance, choreographers cast light on the way bodily movement organizes us. Painting goes beyond depiction and representation to call into question the role of pictures in our lives. Accordingly, we cannot reduce art to some natural aesthetic sense or trigger; recent efforts to frame questions of art in terms of neurobiology and evolutionary theory alone are doomed to fail. By engaging with art, we are able to study ourselves in profoundly novel ways. In fact, art and philosophy have much more in common than we might think. Reframing the conversation around artists and their craft, Strange Tools is a daring and stimulating intervention in contemporary thought. Praise for Strange Tools “With incisive arguments and in crisp and engaging prose, Strange Tools brings the discourse on the function of art and beauty to a different level.” —Science “A stimulating and wide-ranging investigation of the meaning of art . . . A searching and learned response to vexing, long-debated questions.” —Kirkus Reviews “Noë offers a unique analysis on the role of art, and also philosophy, in our lives. Readers with an interest in philosophy, aesthetics, or art will find this an accessible and engaging read.” —Library Journal |

Fascinating from first to last—this is a book that has already prompted the attention and admiration of some of the most prominent scientists and mathematicians. |
| the edge of physics by anil ananthaswamy: Surfing Uncertainty Andy Clark, 2015-10-02 How is it that thoroughly physical material beings such as ourselves can think, dream, feel, create and understand ideas, theories and concepts? How does mere matter give rise to all these non-material mental states, including consciousness itself? An answer to this central question of our existence is emerging at the busy intersection of neuroscience, psychology, artificial intelligence, and robotics. In this groundbreaking work, philosopher and cognitive scientist Andy Clark explores exciting new theories from these fields that reveal minds like ours to be prediction machines - devices that have evolved to anticipate the incoming streams of sensory stimulation before they arrive. These predictions then initiate actions that structure our worlds and alter the very things we need to engage and predict. Clark takes us on a journey in discovering the circular causal flows and the self-structuring of the environment that define the predictive brain. What emerges is a bold, new, cutting-edge vision that reveals the brain as our driving force in the daily surf through the waves of sensory stimulation. |
| the edge of physics by anil ananthaswamy: Six Impossible Things John Gribbin, 2019-10-08 “An elegant and accessible” investigation of quantum mechanics—“highly recommended” for students of the sciences, sci-fi fans, and anyone interested in the strange world of quantum physics (Forbes) Rules of the quantum world seem to say that a cat can be both alive and dead at the same time and a particle can be in two places at once. And that particle is also a wave; everything in the quantum world can described in terms of waves—or entirely in terms of particles. These interpretations were all established by the end of the 1920s, by Erwin Schrödinger, Werner Heisenberg, Paul Dirac, and others. But no one has yet come up with a commonsense explanation of what is going on. In this concise and engaging book, astrophysicist John Gribbin offers an overview of six of the leading interpretations of quantum mechanics. Gribbin calls his account “agnostic,” explaining that none of these interpretations is any better—or any worse—than any of the others. Gribbin presents: • The Copenhagen Interpretation, promoted by Niels Bohr and named by Heisenberg • The Pilot-Wave Interpretation, developed by Louis de Broglie • The Many Worlds Interpretation • The Decoherence Interpretation • The Ensemble “Non-Interpretation” • The Timeless Transactional Interpretation, which theorized waves going both forward and backward in time All of these interpretations are crazy, Gribbin warns, and some are more crazy than others—but in the quantum world, being more crazy does not necessarily mean more wrong. |
| the edge of physics by anil ananthaswamy: How the Hippies Saved Physics: Science, Counterculture, and the Quantum Revival David Kaiser, 2011-06-27 How the Hippies Saved Physics gives us an unconventional view of some unconventional people engaged early in the fundamentals of quantum theory. Great fun to read. —Anton Zeilinger, Nobel laureate in physics The surprising story of eccentric young scientists—among them Nobel laureates John Clauser and Alain Aspect—who stood up to convention and changed the face of modern physics. Today, quantum information theory is among the most exciting scientific frontiers, attracting billions of dollars in funding and thousands of talented researchers. But as MIT physicist and historian David Kaiser reveals, this cutting-edge field has a surprisingly psychedelic past. How the Hippies Saved Physics introduces us to a band of freewheeling physicists who defied the imperative to “shut up and calculate” and helped to rejuvenate modern physics. For physicists, the 1970s were a time of stagnation. Jobs became scarce, and conformity was encouraged, sometimes stifling exploration of the mysteries of the physical world. Dissatisfied, underemployed, and eternally curious, an eccentric group of physicists in Berkeley, California, banded together to throw off the constraints of the physics mainstream and explore the wilder side of science. Dubbing themselves the “Fundamental Fysiks Group,” they pursued an audacious, speculative approach to physics. They studied quantum entanglement and Bell’s Theorem through the lens of Eastern mysticism and psychic mind-reading, discussing the latest research while lounging in hot tubs. Some even dabbled with LSD to enhance their creativity. Unlikely as it may seem, these iconoclasts spun modern physics in a new direction, forcing mainstream physicists to pay attention to the strange but exciting underpinnings of quantum theory. A lively, entertaining story that illuminates the relationship between creativity and scientific progress, How the Hippies Saved Physics takes us to a time when only the unlikeliest heroes could break the science world out of its rut. |

| the edge of physics by anil ananthaswamy: Life's Ratchet Peter M Hoffmann, 2012-10-30 Life is an enduring mystery. Yet, science tells us that living beings are merely sophisticated structures of lifeless molecules. If this view is correct, where do the seemingly purposeful motions of cells and organisms originate? In Life's Ratchet, physicist Peter M. Hoffmann locates the answer to this age-old question at the nanoscale. Below the calm, ordered exterior of a living organism lies microscopic chaos, or what Hoffmann calls the molecular storm -- specialized molecules immersed in a whirlwind of colliding water molecules. Our cells are filled with molecular machines, which, like tiny ratchets, transform random motion into ordered activity, and create the purpose that is the hallmark of life. Tiny electrical motors turn electrical voltage into motion, nanoscale factories custom-build other molecular machines, and mechanical machines twist, untwist, separate and package strands of DNA. The cell is like a city -- an unfathomable, complex collection of molecular workers working together to create something greater than themselves. Life, Hoffman argues, emerges from the random motions of atoms filtered through these sophisticated structures of our evolved machinery. We are agglomerations of interacting nanoscale machines more amazing than anything in science fiction. Rather than relying on some mysterious life force to drive them -- as people believed for centuries -- life's ratchets harness instead the second law of thermodynamics and the disorder of the molecular storm. Grounded in Hoffmann's own cutting-edge research, Life's Ratchet reveals the incredible findings of modern nanotechnology to tell the story of how the noisy world of atoms gives rise to life itself. |
| the edge of physics by anil ananthaswamy: The Man Who Wasn't There Anil Ananthaswamy, 2020-03-05 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.'

The human brain, he argues, is a complex system that not only tells time, but creates it; it constructs our sense of chronological movement and enables mental time travel—simulations of future and past events. These functions are essential not only to our daily lives but to the evolution of the human race: without the ability to anticipate the future, mankind would never have crafted tools or invented agriculture. This virtuosic work of popular science will lead you to a revelation as strange as it is true: your brain is, at its core, a time machine. |
| the edge of physics by anil ananthaswamy: A Grand and Bold Thing Ann K. Finkbeiner, 2012-03-03 In 2005 the Sloan Digital Sky Survey burst onto the scene—an amazingly detailed new map of the universe created by a small group of visionary scientists, led by the beloved and multi-talented astronomer James Gunn—just awarded the National Medal of Science. Suddenly cosmologists were flooded with so many powerful new discoveries that, as one said, it was like drinking out of a fire hose. At last they could trace the universe’s whole history and peer into vast swaths of never before charted deep space. The Sloan survey was put on the web for free, and it has launched a brave new era of “eAstronomy” in which anyone who wants to is free to probe into the beautiful and far-reaching depths of the Sloan map and discover a new galaxy or name a new super-nova. In The Grand and Bold Thing critically acclaimed science writer Ann Finkbeiner tells the inside story of how Gunn and his band of comrades pulled off this remarkable achievement and of the astonishing array of new cosmological findings that the Sloan Survey has made possible. This is a book that cosmology buffs and every armchair astronomer will relish. |
| the edge of physics by anil ananthaswamy: Lost in Math Sabine Hossenfelder, 2020-06-02 A contrarian argues that modern physicists' obsession with beauty has given us wonderful math but bad science Whether pondering black holes or predicting discoveries at CERN, physicists believe the best theories are beautiful, natural, and elegant, and this standard separates popular theories from disposable ones. This is why, Sabine Hossenfelder argues, we have not seen a major breakthrough in the foundations of physics for more than four decades. The belief in beauty has become so dogmatic that it now conflicts with scientific objectivity: observation has been unable to confirm mindboggling theories, like supersymmetry or grand unification, invented by physicists based on aesthetic criteria. Worse, these too good to not be true theories are actually untestable and they have left the field in a cul-de-sac. To escape, physicists must rethink their methods. Only by embracing reality as it is can science discover the truth. |
| the edge of physics by anil ananthaswamy: The Physics of Wall Street James Owen Weatherall, 2013-01-08 A look inside the world of “quants” and how science can (and can’t) predict financial markets: “Entertaining and enlightening” (The New York Times). After the economic meltdown of 2008, Warren Buffett famously warned, “beware of geeks bearing formulas.” But while many of the mathematicians and software engineers on Wall Street failed when their abstractions turned ugly in practice, a special breed of physicists has a much deeper history of revolutionizing finance. Taking us from fin-de-siècle Paris to Rat Pack–era Las Vegas, from wartime government labs to Yippie communes on the Pacific coast, James Owen Weatherall shows how physicists successfully brought their science to bear on some of the thorniest problems in economics, from options pricing to bubbles. The crisis was partly a failure of mathematical modeling. But even more, it was a failure of some very sophisticated financial institutions to think like physicists. Models—whether in science or finance—have limitations; they break down under certain conditions. And in 2008, sophisticated models fell into the hands of people who didn’t understand their purpose, and didn’t care. It was a catastrophic misuse of science. The solution, however, is not to give up on models; it’s to make them better. This book reveals the people and ideas on the cusp of a new era in finance, from a geophysicist using a model designed for earthquakes to predict a massive stock market crash to a physicist-run hedge fund earning 2,478.6% over the course of the 1990s. Weatherall shows how an obscure idea from quantum theory might soon be used to create a far more accurate Consumer Price Index. The Physics of Wall Street will change how we think about our economic future. “Fascinating history . . . Happily, the author has a gift for making complex concepts clear to lay readers.” —Booklist |
| the edge of physics by anil ananthaswamy: The Physics of Everyday Things James Kakalios, 2018-05-15 Physics professor, bestselling author, and dynamic storyteller James Kakalios reveals the mind-bending science behind the seemingly basic things that keep our daily lives running, from our smart phones and digital “clouds” to x-ray machines and hybrid vehicles. Most of us are clueless when it comes to the physics that makes our modern world so convenient. What’s the simple science behind motion sensors, touch screens, and toasters? How do we glide through tolls using an E-Z Pass, or find our way to new places using GPS? In The Physics of Everyday Things, James Kakalios takes us on an amazing journey into the subatomic marvels that underlie so much of what we use and take for granted. Breaking down the world of things into a single day, Kakalios engages our curiosity about how our refrigerators keep food cool, how a plane manages to remain airborne, and how our wrist fitness monitors keep track of our steps. Each explanation is coupled with a story revealing the interplay of the astonishing invisible forces that surround us. Through this “narrative physics,” The Physics of Everyday Things demonstrates that—far from the abstractions conjured by terms like the Higgs Boson, black holes, and gravity waves—sophisticated science is also quite practical. With his signature clarity and inventiveness, Kakalios ignites our imaginations and enthralls us with the principles that make up our lives. |

| the edge of physics by anil ananthaswamy: Einstein in Berlin Thomas Levenson, 2017-05-23 In a book that is both biography and the most exciting form of history, here are eighteen years in the life of a man, Albert Einstein, and a city, Berlin, that were in many ways the defining years of the twentieth century. Einstein in Berlin In the spring of 1913 two of the giants of modern science traveled to Zurich. Their mission: to offer the most prestigious position in the very center of European scientific life to a man who had just six years before been a mere patent clerk. Albert Einstein accepted, arriving in Berlin in March 1914 to take up his new post. In December 1932 he left Berlin forever. “Take a good look,” he said to his wife as they walked away from their house. “You will never see it again.” In between, Einstein’s Berlin years capture in microcosm the odyssey of the twentieth century. It is a century that opens with extravagant hopes--and climaxes in unparalleled calamity. These are tumultuous times, seen through the life of one man who is at once witness to and architect of his day--and ours. He is present at the events that will shape the journey from the commencement of the Great War to the rumblings of the next one. We begin with the eminent scientist, already widely recognized for his special theory of relativity. His personal life is in turmoil, with his marriage collapsing, an affair under way. Within two years of his arrival in Berlin he makes one of the landmark discoveries of all time: a new theory of gravity--and before long is transformed into the first international pop star of science. He flourishes during a war he hates, and serves as an instrument of reconciliation in the early months of the peace; he becomes first a symbol of the hope of reason, then a focus for the rage and madness of the right. And throughout these years Berlin is an equal character, with its astonishing eruption of revolutionary pathways in art and architecture, in music, theater, and literature. Its wild street life and sexual excesses are notorious. But with the debacle of the depression and Hitler’s growing power, Berlin will be transformed, until by the end of 1932 it is no longer a safe home for Einstein. Once a hero, now vilified not only as the perpetrator of “Jewish physics” but as the preeminent symbol of all that the Nazis loathe, he knows it is time to leave. |

What does it mean to “be you”—that is, to have a specific, conscious experience of the world around you and yourself within it? There may be no more elusive or fascinating question. Historically, humanity has considered the nature of consciousness to be a primarily spiritual or philosophical inquiry, but scientific research is now mapping out compelling biological theories and explanations for consciousness and selfhood. Now, internationally renowned neuroscience professor, researcher, and author Anil Seth is offers a window into our consciousness in BEING YOU: A New Science of Consciousness. Anil Seth is both a leading expert on the neuroscience of consciousness and one of most prominent spokespeople for this relatively new field of science. His radical argument is that we do not perceive the world as it objectively is, but rather that we are prediction machines, constantly inventing our world and correcting our mistakes by the microsecond, and that we can now observe the biological mechanisms in the brain that accomplish this process of consciousness. Seth has been interviewed for documentaries aired on the BBC, Netflix, and Amazon and podcasts by Sam Harris, Russell Brand, and Chris Anderson, and his 2017 TED Talk on the topic has been viewed over 11 million times, a testament to his uncanny ability to make unimaginably complex science accessible and entertaining. |

Penrose presents a new perspective on three of cosmology’s essential questions: What came before the Big Bang? What is the source of order in our universe? And what cosmic future awaits us? He shows how the expected fate of our ever-accelerating and expanding universe—heat death or ultimate entropy—can actually be reinterpreted as the conditions that will begin a new “Big Bang.” He details the basic principles beneath our universe, explaining various standard and non-standard cosmological models, the fundamental role of the cosmic microwave background, the paramount significance of black holes, and other basic building blocks of contemporary physics. Intellectually thrilling and widely accessible, Cycles of Time is a welcome new contribution to our understanding of the universe from one of our greatest mathematicians and thinkers. |

One of GQ's 50 Best Books of Literary Journalism of the 21st Century Just before the 2002 season opens, the Oakland Athletics must relinquish its three most prominent (and expensive) players and is written off by just about everyone—but then comes roaring back to challenge the American League record for consecutive wins. How did one of the poorest teams in baseball win so many games? In a quest to discover the answer, Michael Lewis delivers not only “the single most influential baseball book ever” (Rob Neyer, Slate) but also what “may be the best book ever written on business” (Weekly Standard). Lewis first looks to all the logical places—the front offices of major league teams, the coaches, the minds of brilliant players—but discovers the real jackpot is a cache of numbers?numbers!?collected over the years by a strange brotherhood of amateur baseball enthusiasts: software engineers, statisticians, Wall Street analysts, lawyers, and physics professors. What these numbers prove is that the traditional yardsticks of success for players and teams are fatally flawed. Even the box score misleads us by ignoring the crucial importance of the humble base-on-balls. This information had been around for years, and nobody inside Major League Baseball paid it any mind. And then came Billy Beane, general manager of the Oakland Athletics. He paid attention to those numbers?with the second-lowest payroll in baseball at his disposal he had to?to conduct an astonishing experiment in finding and fielding a team that nobody else wanted. In a narrative full of fabulous characters and brilliant excursions into the unexpected, Michael Lewis shows us how and why the new baseball knowledge works. He also sets up a sly and hilarious morality tale: Big Money, like Goliath, is always supposed to win . . . how can we not cheer for David? |

| the edge of physics by anil ananthaswamy: Quantum Chance Nicolas Gisin, 2014-07-30 Quantum physics, which offers an explanation of the world on the smallest scale, has fundamental implications that pose a serious challenge to ordinary logic. Particularly counterintuitive is the notion of entanglement, which has been explored for the past 30 years and posits an ubiquitous randomness capable of manifesting itself simultaneously in more than one place. This amazing 'non-locality' is more than just an abstract curiosity or paradox: it has entirely down-to-earth applications in cryptography, serving for example to protect financial information; it also has enabled the demonstration of 'quantum teleportation', whose infinite possibilities even science-fiction writers can scarcely imagine. This delightful and concise exposition does not avoid the deep logical difficulties of quantum physics, but gives the reader the insights needed to appreciate them. From 'Bell's Theorem' to experiments in quantum entanglement, the reader will gain a solid understanding of one of the most fascinating areas of contemporary physics. |

| the edge of physics by anil ananthaswamy: The Secret History of the Mongol Queens Jack Weatherford, 2010-02-16 “A fascinating romp through the feminine side of the infamous Khan clan” (Booklist) by the author featured in Echoes of the Empire: Beyond Genghis Khan “Enticing . . . hard to put down.”—Associated Press The Mongol queens of the thirteenth century ruled the largest empire the world has ever known. The daughters of the Silk Route turned their father’s conquests into the first truly international empire, fostering trade, education, and religion throughout their territories and creating an economic system that stretched from the Pacific to the Mediterranean. Yet sometime near the end of the century, censors cut a section about the queens from the Secret History of the Mongols, and, with that one act, the dynasty of these royals had seemingly been extinguished forever, as even their names were erased from the historical record. With The Secret History of the Mongol Queens, a groundbreaking and magnificently researched narrative, Jack Weatherford restores the queens’ missing chapter to the annals of history. |
| the edge of physics by anil ananthaswamy: From Eternity to Here Sean Carroll, 2010-01-07 A rising star in theoretical physics offers his awesome vision of our universe and beyond, all beginning with a simple question: Why does time move forward? Time moves forward, not backward—everyone knows you can’t unscramble an egg. In the hands of one of today’s hottest young physicists, that simple fact of breakfast becomes a doorway to understanding the Big Bang, the universe, and other universes, too. In From Eternity to Here, Sean Carroll argues that the arrow of time, pointing resolutely from the past to the future, owes its existence to conditions before the Big Bang itself—a period modern cosmology of which Einstein never dreamed. Increasingly, though, physicists are going out into realms that make the theory of relativity seem like child’s play. Carroll’s scenario is not only elegant, it’s laid out in the same easy-to- understand language that has made his group blog, Cosmic Variance, the most popular physics blog on the Net. From Eternity to Here uses ideas at the cutting edge of theoretical physics to explore how properties of spacetime before the Big Bang can explain the flow of time we experience in our everyday lives. Carroll suggests that we live in a baby universe, part of a large family of universes in which many of our siblings experience an arrow of time running in the opposite direction. It’s an ambitious, fascinating picture of the universe on an ultra-large scale, one that will captivate fans of popular physics blockbusters like Elegant Universe and A Brief History of Time.

| the edge of physics by anil ananthaswamy: Epistemology of Experimental Gravity - Scientific Rationality Nicolae Sfetcu, 2019 The evolution of gravitational tests from an epistemological perspective framed in the concept of rational reconstruction of Imre Lakatos, based on his methodology of research programmes. Unlike other works on the same subject, the evaluated period is very extensive, starting with Newton's natural philosophy and up to the quantum gravity theories of today. In order to explain in a more rational way the complex evolution of the gravity concept of the last century, I propose a natural extension of the methodology of the research programmes of Lakatos that I then use during the paper. I believe that this approach offers a new perspective on how evolved over time the concept of gravity and the methods of testing each theory of gravity, through observations and experiments. I argue, based on the methodology of the research programmes and the studies of scientists and philosophers, that the current theories of quantum gravity are degenerative, due to the lack of experimental evidence over a long period of time and of self-immunization against the possibility of falsification. Moreover, a methodological current is being developed that assigns a secondary, unimportant role to verification through observations and/or experiments. For this reason, it will not be possible to have a complete theory of quantum gravity in its current form, which to include to the limit the general relativity, since physical theories have always been adjusted, during their evolution, based on observational or experimental tests, and verified by the predictions made. Also, contrary to a widespread opinion and current active programs regarding the unification of all the fundamental forces of physics in a single final theory, based on string theory, I argue that this unification is generally unlikely, and it is not possible anyway for a unification to be developed based on current theories of quantum gravity, including string theory. In addition, I support the views of some scientists and philosophers that currently too much resources are being consumed on the idea of developing quantum gravity theories, and in particular string theory, to include general relativity and to unify gravity with other forces, as long as science does not impose such research programs.

| the edge of physics by anil ananthaswamy: You Look Like a Thing and I Love You Janelle Shane, 2019-11-05 As heard on NPR's Science Friday, discover the book recommended by Malcolm Gladwell, Susan Cain, Daniel Pink, and Adam Grant: an accessible, informative, and hilarious introduction to the weird and wonderful world of artificial intelligence (Ryan North). You look like a thing and I love you is one of the best pickup lines ever . . . according to an artificial intelligence trained by scientist Janelle Shane, creator of the popular blog AI Weirdness. She creates silly AIs that learn how to name paint colors, create the best recipes, and even flirt (badly) with humans—all to understand the technology that governs so much of our daily lives. We rely on AI every day for recommendations, for translations, and to put cat ears on our selfie videos. We also trust AI with matters of life and death, on the road and in our hospitals. But how smart is AI really... and how does it solve problems, understand humans, and even drive self-driving cars? Shane delivers the answers to every AI question you've ever asked, and some you definitely haven't. Like, how can a computer design the perfect sandwich? What does robot-generated Harry Potter fan-fiction look like? And is the world's best Halloween costume really Vampire Hog Bride? In this smart, often hilarious introduction to the most interesting science of our time, Shane shows how these programs learn, fail, and adapt—and how they reflect the best and worst of humanity. You Look Like a Thing and I Love You is the perfect book for anyone curious about what the robots in our lives are thinking. I can't think of a better way to learn about artificial intelligence, and I've never had so much fun along the way. —Adam Grant, New York Times bestselling author of Originals |
| the edge of physics by anil ananthaswamy: Kabbalah Shahar Arzy, Moshe Idel, 2015-01-01 In this original study, Moshe Idel, an eminent scholar of Jewish mysticism and thought, and the cognitive neuroscientist and neurologist Shahar Arzy combine their considerable expertise to explore the mysteries of the Kabbalah from an entirely new perspective: that of the human brain. In lieu of the theological, sociological, and psychoanalytic approaches that have generally dominated the study of ecstatic mystical experiences, the authors endeavor to decode the brain mechanisms underlying these phenomena. Arzy and Idel analyze first-person descriptions to explore the Kabbalistic techniques employed by most prominent Jewish mystics to effect bodily reduplications, dissociations, and other phenomena, and compare them with recent neurological observationsand modern-day laboratory experiments. The resultant study offers readers a scientific, more brain-based understanding of how ecstatic Kabbalists achieved their most precious mystical experiences. The study further demonstrates how these Kabbalists have long functioned as pioneering investigators of the human self-- |
| the edge of physics by anil ananthaswamy: The End of Everything Katie Mack, 2020-08-04 A NEW YORK TIMES NOTABLE BOOK * AN NPR SCIENCE FRIDAY BOOK CLUB SELECTION* NAMED A BEST BOOK OF THE YEAR BY THE WASHINGTON POST, THE ECONOMIST, NEW SCIENTIST, PUBLISHERS WEEKLY, and THE GUARDIAN From the cohost of the podcast The Universe with John Green and one of the most dynamic stars in astrophysics, an “engrossing, elegant” (The New York Times) look at five ways the universe could end, and the mind-blowing lessons each scenario reveals about the most important concepts in cosmology. We know the universe had a beginning. With the Big Bang, it expanded from a state of unimaginable density to an all-encompassing cosmic fireball to a simmering fluid of matter and energy, laying down the seeds for everything from black holes to one rocky planet orbiting a star near the edge of a spiral galaxy that happened to develop life as we know it. But what happens to the universe at the end of the story? And what does it mean for us now? Dr. Katie Mack has been contemplating these questions since she was a young student, when her astronomy professor informed her the universe could end at any moment, in an instant. This revelation set her on the path toward theoretical astrophysics. Now, with lively wit and humor, she takes us on a mind-bending tour through five of the cosmos’s possible finales: the Big Crunch, Heat Death, the Big Rip, Vacuum Decay (the one that could happen at any moment!), and the Bounce. Guiding us through cutting-edge science and major concepts in quantum mechanics, cosmology, string theory, and much more, The End of Everything is a wildly fun, surprisingly upbeat ride to the farthest reaches of all that we know. |
| the edge of physics by anil ananthaswamy: Probable Impossibilities Alan Lightman, 2021-02-09 The acclaimed author of Einstein’s Dreams tackles big questions like the origin of the universe and the nature of consciousness ... in an entertaining and easily digestible way” (Wall Street Journal) with a collection of meditative essays on the possibilities—and impossibilities—of nothingness and infinity, and how our place in the cosmos falls somewhere in between. Can space be divided into smaller and smaller units, ad infinitum? Does space extend to larger and larger regions, on and on to infinity? Is consciousness reducible to the material brain and its neurons? What was the origin of life, and can biologists create life from scratch in the lab? Physicist and novelist Alan Lightman, whom The Washington Post has called “the poet laureate of science writers,” explores these questions and more—from the anatomy of a smile to the capriciousness of memory to the specialness of life in the universe to what came before the Big Bang. Probable Impossibilities is a deeply engaged consideration of what we know of the universe, of life and the mind, and of things vastly larger and smaller than ourselves. |
