A.I. and Genius Machines by the editors of Scientific American In science fiction, artificial intelligence takes the shape of computers that can speak like people, think for themselves, and sometimes act against us. Sometimes the machines seem to know everything, and symbolize implacable and unknowable power, as in The Matrix. Such machines can also embody the limits of logic, and by extension our own powers of reason. In Arthur C. Clarke's 2001: A Space Odyssey, HAL was a computer of vast capability driven insane by the demands of his programming – to honestly and completely report information – when those instructions conflicted with orders to keep state secrets. Star Trek has given us the android, Lieutenant Commander Data, who strives to be more human. None of these visions came true in quite the way science fiction writers imagined, even though in many ways computers surpass their fictional counterparts. This eBook reviews work in the field and covers topics from chess-playing to quantum computing. The writers tackle how to make computers more powerful, how we define consciousness, what the hard problems are and even how computers might be built once the limits of silicon chips have been reached. Artificial intelligence also raises some thorny ethical questions, such as whether morality can be programmed. These are kinds of issues that make artificial intelligence and computing fascinating. Building an intelligent machine brings together the human desire to create and the question of what makes us what we are. If anyone ever builds a true thinking machine, that last question becomes much more complicated, not less. Data and HAL would probably agree.

The Higgs Boson: Searching for the God Particle by the Editors of Scientific American Updated 2017 Edition! For the fifth anniversary of one of the biggest discoveries in physics, we’ve updated this eBook to include our continuing analysis of the discovery, of the questions it answers and those it raises. As the old adage goes, where there’s smoke, there’s fire. Where there is effect, there must be cause. The planet Neptune was found in 1846 because the mathematics of Newton's laws, when applied to the orbit of Uranus, said some massive body had to be there. Astronomers eventually found it, using the best telescopes available to peer into the sky. This same logic is applied to the search for the Higgs boson. One consequence of the prevailing theory of physics, called the Standard Model, is that there has to be some field that gives particles their particular masses. With that there has to be a corresponding particle, made by creating waves in the field, and this is the Higgs boson, the so-called God particle. This eBook chronicles the search – and demonstrates the power of a good theory. Based on the Standard Model, physicists believed something had to be there, but it wasn't until the Large Hadron Collider was built that anyone could see evidence of the Higgs – and finally in July 2012, they did. A Higgs-like particle was found near the energies scientists expected to find it. Now, armed with better evidence and better questions, the scientific process continues. This eBook gathers the best reporting and analysis from Scientific American to explain that process – the theories, the search, the ongoing questions. In essence, everything you need to know to separate Higgs from hype.

The fundamental outlines of the physical world, from its tiniest particles to massive galaxy clusters, have been apparent for decades. Does this mean physicists are about to tie it all up into a neat package? Not at all. Just when you think you’re figuring it out, the universe begins to look its strangest. This eBook, “Ultimate Physics: From Quarks to the Cosmos,” illustrates clearly how answers often lead to more questions and open up new paths to insight. We open with “The Higgs at Last,” which looks behind the scenes of one of the most anticipated discoveries in physics and examines how this “Higgs-like” particle both confirmed and confounded expectations. In “The Inner Life of Quarks,” author Don Lincoln discusses evidence that quarks and leptons may not be the smallest building blocks of matter. Section Two switches from the smallest to the largest of scales, and in “Origin of the Universe,” Michael Turner analyzes a number of speculative scenarios about how it all began. Another two articles examine the mystery of dark energy and some doubts as to whether it exists at all. In the last section, we look at one of the most compelling problems in physics: how to tie together the very small and the very large – quantum mechanics and general relativity. In one article, Stephen Hawking and Leonard Mlodinow argue that a so-called “theory of everything” may be out of reach, and in another, David Deutsch and Artur Ekert question the view that quantum mechanics imposes limits on knowledge, arguing instead that the theory has an intricacy that allows for new, practical technologies, including powerful computers that can reach their true potential.

In the world of physics, very little in the universe is what it first appears to be. And science fiction has imagined some pretty wild ideas about how the universe could work – from hidden extra dimensions in Interstellar to life as a mental projection in The Matrix. But these imaginings seem downright tame compared with the mind-bending science now coming out of physics and astronomy, and in this eBook, Physics: New Frontiers, we look at the strange and fascinating discoveries shaping (and reshaping) the field today. In the world of astrophysics, the weirdness begins at the moment of creation. In “The Black Hole at the Beginning of Time,” the authors discuss theories of what might have come before the big bang. Could our 3-D universe have sprung from the formation of a black hole in a 4-D cosmos? The math says: maybe. Later, in “The Giant Bubbles of the Milky Way,” the authors describe massive structures dubbed “Fermi bubbles” at its center – structures that no one noticed until recently. Technological innovations make much of this new science possible, as we see again in “Neutrinos at the Ends of the Earth,” where 5,000-odd sensors frozen deep within a cubic kilometer of ice in Antarctica aim to catch neutrinos in order to study distant cosmic phenomena. Scientists are also dissecting molecules with the most powerful x-ray laser in the world, as explored in “The Ultimate X-ray Machine.” Even our most fundamental notions of what reality is are up for debate, as examined in “Does the Multiverse Really Exist?” and the aptly named “What Is Real?” in which the authors question whether particles are indeed material things at all. While all of this abstraction might seem like a fun exercise in mental gymnastics, living things must also abide by the laws of physics, which, according to “The Limits of Intelligence,” may prevent our brains from evolving further. Then again, as we’ve learned, things could be different than they appear...

How exactly do children become the adults they were meant to be? In this eBook, Understanding Child Development, we investigate this profoundly complicated process from infancy through early childhood (the teenage years will be covered in a separate eBook). Included in this collection are several seminal studies on infant cognition where researchers found evidence that many of our abilities are "pre-programmed." For example, in "The Visual Cliff," Eleanor Gibson explains her findings that most human infants are able to judge depth as soon as they can crawl, suggesting that we are born with an ability to perceive falling-off places without having to go through the trial-and-error process. Section 2 looks at how we learn to communicate using both symbols and language. Judy DeLoache's story, "Mindful of Symbols," examines the process that toddlers must go through to learn to discriminate between an object and a representation of that object, such as a photograph. With the ability to communicate comes social development, covered in Section 3. In it, Melinda Wenner Moyer argues that play time is essential for healthy social adjustment in "The Serious Need for Play," while Stefanie Reinberger discusses the link between temper tantrums and violent tendencies later in life in "Tempering Tantrums." The fourth section focuses on developmental disorders, from ADHD to Down syndrome, autism and less common diseases that are linked to faulty genomic imprinting, discussed in a piece by Melinda Wenner Moyer called "A Patchwork Mind." Finally, we end with a section on parenting, which includes a Q&A with noted anthropologist Sarah Blaffer Hrdy on the evolutionary lessons of motherhood-why cooperative parenting and community-based childrearing is not only better for kids, but essential to their healthy development.

Who do we love? Who loves us? And why? Is love really a mystery, or can neuroscience offer some answers to these age-old questions? In her third enthralling book about the brain, Judith Horstman takes us on a lively tour of our most important sex and love organ and the whole smorgasbord of our many kinds of love-from the bonding of parent and child to the passion of erotic love, the affectionate love of companionship, the role of animals in our lives, and the love of God. Drawing on the latest neuroscience, she explores why and how we are born to love-how we're hardwired to crave the companionship of others, and how very badly things can go without love. Among the findings: parental love makes our brain bigger, sex and orgasm make it healthier, social isolation makes it miserable-and although the craving for romantic love can be described as an addiction, friendship may actually be the most important loving relationship of your life. Based on recent studies and articles culled from the prestigious Scientific American and Scientific American Mind magazines, The Scientific American Book of Love, Sex, and the Brain offers a fascinating look at how the brain controls our loving relationships, most intimate moments, and our deep and basic need for connection.

From the Scopes “Monkey Trial” of 1925 to the court ruling against the Dover Area School Board’s proposed intelligent design curriculum in 2005, few scientific topics have engendered as much controversy—or grabbed as many headlines—as evolution. And since the debate shows no signs of abating, there is perhaps no better time to step back and ask: What is evolution? Defined as the gradual process by which something changes into a different and usually more complex and efficient form, evolution explains the formation of the universe, the nature of viruses, and the emergence of humans. A first-rate summary of the actual science of evolution, this Scientific American reader is a timely collection that gives readers an opportunity to consider evolution’s impact in various settings. Divided into four sections that consider the evolution of the universe, cells, dinosaurs, and humans, Evolution brings together more than thirty articles written by some of the world’s most respected evolutionary scientists. As tour guides through the genesis of the universe and complex cells, P. James E. Peebles examines the evidence in support of an expanding cosmos, while Christian de Duve discusses the birth of eukaryotes. In an article that anticipated his book Full House, Stephen Jay Gould argues that chance and contingency are as important as natural selection for evolutionary change. And Ian Tatersall makes two fascinating contributions, submitting his view that the schematic of human evolution looks less like a ladder and more like a bush. With the latest on what’s being researched at every level of evolutionary studies, from prospects of life on other planets to the inner working of cells, Evolution offers general readers an opportunity to update their knowledge on this hot topic while giving students an introduction to the problems and methodologies of an entire field of inquiry.

Brain disease such as Alzheimer’s and Parkinson’s affect an estimated one in six Americans and are increasing in incidence as the population ages. In this eBook, Fragile Brain: Neurodegenerative Diseases, we examine these and other conditions involving the damage and loss of neurons, including other forms of dementia, amyotrophic lateral sclerosis (ALS), chronic traumatic encephalopathy (CTE) and multiple sclerosis (MS). In “The Seeds of Dementia,” the authors discuss evidence of prions and protein misfolding as a universal culprit in Alzheimer’s and other conditions. Later, two articles by Gary Stix report on ongoing research into a cluster of Columbian families that experience early onset symptoms of Alzheimer’s. Researchers studying the genes and progression of disease in these families hope that results will reveal clues about its course and possible future remedies. In “New Movement in Parkinson’s,” the authors outline abnormal cell behavior and genetic mutations that may be behind the disease. In the study of ALS, Amy Yee examines research into why eye muscles tend to last longer than other motor neurons and what this may mean for treatment. Other pieces look at new lines of inquiry in MS, including why researchers are turning to gray matter, as opposed to white matter, as the starting point for the disease. We wrap up this collection with current preventative measures and treatments that target not only disease pathology, but also lifestyle changes as well. In “A Rare Success against Alzheimer’s,” the results of a large-scale Finnish study provide evidence that choices such as diet and exercise can help prevent cognitive decline. Although this news is far from a cure, forward movement against Alzheimer’s – and neurodegenerative disease in general – is reason for optimism. As research and evidence accumulates, we get ever closer to curative therapies that can halt the debilitation and death of neurons.

The Magic and Mystery of Numbers

How many people achieve a cult following because of their writing in mathematics? Only a handful, and Martin Gardner is among the most well known and well loved. Not only did he present a notoriously difficult subject in an engaging and accessible way, but in doing so, he attracted an incredibly broad readership. His correspondents ranged from academics like Roger Penrose and John Horton Conway to artists MC Escher and Salvador Dali to writer Isaac Asimov. His "Mathematical Games" column in Scientific American ran nearly every month for 26 years and was one of the most popular in the magazine's history. Gardner would have celebrated his 100th birthday this October, and to mark the occasion we've created this eBook collection, Martin Gardner: The Magic and Mystery of Numbers. In this anthology, we strove to create a new "slice" through his wealth of material. Here, we focus on all flavors of number, from common integers and negative numbers to figurate numbers and the exotic random number, Omega, which can be described but not computed. Some of these columns are less well known than, say, his writings about flexagons, but they are no less fun. In true Gardner fashion, they leap from magic and games—as well as art, music, and literature—to flashes of deep mathematical insight. Lattice integers become a billiards challenge and surreal numbers spawn a host of related games. The "abracadabric number e," quoting French entomologist Jean-Henri Fabre, leads to spiders' webs and compounded interest. The binary Gray code inspires a poem and cracks the classic Chinese Rings puzzle. And binary numbers unlock mind-reading tricks and the Tower of Hanoi. Almost every column offers up problems for readers to solve and test their understanding—along with the answers for anyone easily frustrated. We hope that they will prove as inspirational to readers now as they did to earlier audiences.
