A Question of Time: The Ultimate Paradox by the Editors of Scientific American "What time is it?" That simple question is probably asked more often in contemporary society than ever before. In our clock-studded world, the answer is never more than a glance away, and so we can blissfully partition our days into ever smaller increments for ever more tightly scheduled tasks. Modern scientific revelations about time, however, make the question endlessly frustrating. If we seek a precise knowledge of the time, the infinitesimal flash of now dissolves into a scattering flock of nanoseconds. Because we are bound by the speed of light and the velocity of nerve impulses, our perception of the "present" reflects the world as it occurred an instant ago – for all that human consciousness pretends otherwise, we can never catch up. Even in principle, perfect synchronicity escapes us. Relativity dictates that, like a strange syrup, time flows slower on moving trains than in the stations and faster in the mountains than in the valleys. The time for our wristwatch is not exactly the same as the time for our head. This eBook, A Question of Time, summarizes what science has discovered about how time permeates and guides both our physical world and our inner selves. That knowledge should enrich the imagination and provide practical advantages to anyone hoping to beat the clock, or at least to stay in step with it. Synchronize your watches...

The Future of Energy: Earth, Wind and Fire by the Editors of Scientific American Since the Industrial Revolution our civilization has depended on fossil fuels to generate energy – first it was coal; then petroleum. But there are two problems: the first is that petroleum isn't an infinite resource; and the second is that burning coal and oil puts billions of tons of carbon dioxide into the atmosphere, trapping heat. Temperatures have risen by about 0.6 degrees Celsius over the last 100 years, which may not sound like much, but even that small increase is showing some large effects. For one, records have been set for the seasonal loss of arctic ice. If business as usual continues, we are looking at a world where sea levels will be high enough to submerge many coastal cities and extreme weather events like 2012's Hurricane Sandy are the new normal. In this eBook, The Future of Energy: Earth, Wind and Fire, we review the energy problem and analyze the options from the mundane to the far out, beginning in Section One with an overview of issues and solutions, including the comprehensive "A Path to Sustainable Energy by 2030" and "7 Radical Energy Solutions." As these authors show, a multitude of possibilities exist. Renewable energy is more than photovoltaic cells and wind turbines – though these are viable options – and subsequent sections look at various sources, including solar power, hydropower, geothermal power, nuclear power and yes, wind power. For example, Section 4's "Can Nuclear Power Compete" examines the possibilities for nuclear rebirth and Section 5's "Turning the Tide" and "Moving Parts" discuss how tides could power coastal cities. Meanwhile we need to power transportation, and Section 7 reviews the search for biofuels that do not negatively impact the environment. Of course, all technologies have drawbacks that must be addressed, and not every idea will succeed. That isn't the point. There's no choice but to change the way we power our lives. The question is how and when. The longer we wait, the more painful the transition will be.

Have you ever wondered what’s happening in your brain as you go through a typical day and night? This fascinating book presents an hour-by-hour round-the-clock journal of your brain’s activities. Drawing on the treasure trove of information from Scientific American and Scientific American Mind magazines as well as original material written specifically for this book, Judith Horstman weaves together a compelling description of your brain at work and at play. The Scientific American Day in the Life of Your Brain reveals what’s going on in there while you sleep and dream, how your brain makes memories and forms addictions and why we sometimes make bad decisions. The book also offers intriguing information about your emotional brain, and what’s happening when you’re feeling love, lust, fear and anxiety—and how sex, drugs and rock and roll tickle the same spots. Based on the latest scientific information, the book explores your brain’s remarkable ability to change, how your brain can make new neurons even into old age and why multitasking may be bad for you. Your brain is uniquely yours – but research is showing many of its day-to-day cycles are universal. This book gives you a look inside your brain and some insights into why you may feel and act as you do. The Scientific American Day in the Life of Your Brain is written in the entertaining, informative and easy-to-understand style that fans of Scientific American and Scientific American Mind magazine have come to expect.

Forever Young: The Science of Aging by the Editors of Scientific American Today, an infant born in the US will probably live to see his or her 78th birthday, a 20- year-plus increase over the average lifespan a century ago. While living well into the 80s and 90s is becoming more and more attainable, how many more years can humanity expect to gain? The two main barriers are accumulated damage to cells and organs that occurs over time and age-related illnesses like cancer and Alzheimer's disease. Researchers are divided over where to pour their efforts, and in this eBook, Forever Young: The Science of Aging we take a look at what science knows—and what it's striving to learn—about the aging process. Both genes and environment influence how long people live and how "well" they age, as discussed in Section 1, "A Matter of Time: The Aging Process." The eBook opens with "Why Can't We Live Forever," where author Thomas Kirkwood explains exactly why by way of his "disposable soma" theory. Other theories of how we age, including the role of telomeres, free radicals and caloric restriction, are discussed in subsequent sections. Recent studies have called into question long-held beliefs about the anti-aging benefits of antioxidants and reducing caloric intake. Though there are a number of age-related illnesses, few are so devastating as Alzheimer's disease, covered in its own section. While there's still no cure, a slew of clinical drug trials is underway. Finally, we examine the quest for longevity, featuring stories on both life-extension research and lifestyle choices. In particular, "Fit Body, Fit Mind?" looks at how to prevent age-related mental decline by staying physically fit and socially involved. So while there's no miracle pill on the horizon that will extend our lives to 150, we can certainly make the most of the years we do have.

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.
