    Kate Biberdorf, aka "Kate the Chemist," reveals the fascinating science we experience every day Have you ever wondered what makes dough rise? Or how your morning coffee gives you that energy boost? Or why your shampoo is making your hair look greasy? The answer is chemistry. From the moment we wake up until the time we go to sleep (and even while we sleep), chemistry is at work—and it doesn't take a PhD in science to understand it. Dr. Biberdorf has appeared on TV programs from the Today show to The Late Show with Stephen Colbert, lighting the world on fire and changing the face of chemistry as we know it. In It's Elemental, she demystifies the fundamental principles of the science that may have eluded you in high school and shows how chemistry comes alive in everything we do. With wry wit and infectious enthusiasm, this entertaining guide will ignite your passion for science and change the way you experience the world.

    Breaking down the symbols themselves, they pose a series of questions: What is energy? What is mass? What has the speed of light got to do with energy and mass? In answering these questions, they take us to the site of one of the largest scientific experiments ever conducted. Lying beneath the city of Geneva, straddling the Franco-Swiss boarder, is a 27 km particle accelerator, known as the Large Hadron Collider. Using this gigantic machine—which can recreate conditions in the early Universe fractions of a second after the Big Bang—Cox and Forshaw will describe the current theory behind the origin of mass.Alongside questions of energy and mass, they will consider the third, and perhaps, most intriguing element of the equation: 'c' - or the speed of light. Why is it that the speed of light is the exchange rate? Answering this question is at the heart of the investigation as the authors demonstrate how, in order to truly understand why E=mc2, we first must understand why we must move forward in time and not backwards and how objects in our 3-dimensional world actually move in 4-dimensional space-time. In other words, how the very fabric of our world is constructed. A collaboration between two of the youngest professors in the UK, Why Does E=mc2? promises to be one of the most exciting and accessible explanations of the theory of relativity in recent years.

    The result is the most authoritative and scientifically accurate description of the revolutionary developments taking place in medicine, computers, artificial intelligence, nanotechnology, energy production, and astronautics.In all likelihood, by 2100 we will control computers via tiny brain sensors and, like magicians, move objects around with the power of our minds. Artificial intelligence will be dispersed throughout the environment, and Internet-enabled contact lenses will allow us to access the world's information base or conjure up any image we desire in the blink of an eye.Meanwhile, cars will drive themselves using GPS, and if room-temperature superconductors are discovered, vehicles will effortlessly fly on a cushion of air, coasting on powerful magnetic fields and ushering in the age of magnetism.Using molecular medicine, scientists will be able to grow almost every organ of the body and cure genetic diseases. Millions of tiny DNA sensors and nanoparticles patrolling our blood cells will silently scan our bodies for the first sign of illness, while rapid advances in genetic research will enable us to slow down or maybe even reverse the aging process, allowing human life spans to increase dramatically.In space, radically new ships—needle-sized vessels using laser propulsion—could replace the expensive chemical rockets of today and perhaps visit nearby stars. Advances in nanotechnology may lead to the fabled space elevator, which would propel humans hundreds of miles above the earth's atmosphere at the push of a button.But these astonishing revelations are only the tip of the iceberg. Kaku also discusses emotional robots, antimatter rockets, X-ray vision, and the ability to create new life-forms, and he considers the development of the world economy. He addresses the key questions: Who are the winner and losers of the future? Who will have jobs, and which nations will prosper?All the while, Kaku illuminates the rigorous scientific principles, examining the rate at which certain technologies are likely to mature, how far they can advance, and what their ultimate limitations and hazards are. Synthesizing a vast amount of information to construct an exciting look at the years leading up to 2100, Physics of the Future is a thrilling, wondrous ride through the next 100 years of breathtaking scientific revolution.

    She delves into the science behind inventions, the steps various people took to create and improve upon ideas as they evolved, and the ways in which young inventors can continue to think about and understand what it means to tinker, to fiddle, and to innovate. And laced throughout it all, Temple gives us glimpses into her own childhood tinkering, building, and inventing.More than a blueprint for how to build things, in Calling All Minds Temple Grandin creates a blueprint for different ways to look at the world. And more than a call to action, she gives a call to imagination, and shows readers that there is truly no single way to approach any given problem--but that an open and inquisitive mind is always key.*Includes a Bonus PDF with projects, patents, photos and drawings from the author.

    He couldn't believe the crowded, glittering night sky at the planetarium was real--until a visit to the country years later revealed the impossible.That discovery was like rocket fuel for Neil's passion about space. His quest for knowledge took him from the roof of his apartment building to a science expedition in northwest Africa, to a summer astronomy camp beneath a desert sky, and finally back home to become the director of the Hayden Planetarium, where it all began. Before long, Neil became America's favorite guide to the cosmos.This story of how one boy's quest for knowledge about space leads him to become a star scientist is perfect for young readers who are fascinated by the universe, aspiring scientists, and the dreamer in all of us.

    It’s time. Today is the day he will once again cast himself into the air, spiral upward into the clouds, and bank into the wind.He wears a black band on his lower right leg and an orange flag on his upper left, bearing the laser inscription B95. Scientists call him the Moonbird because, in the course of his astoundingly long lifetime, this gritty, four-ounce marathoner has flown the distance to the moon—and halfway back! B95 is a robin-sized shorebird, a red knot of the subspecies rufa. Each February he joins a flock that lifts off from Tierra del Fuego, headed for breeding grounds in the Canadian Arctic, nine thousand miles away.  Late in the summer, he begins the return journey. B95 can fly for days without eating or sleeping, but eventually he must descend to refuel and rest. However, recent changes at ancient refueling stations along his migratory circuit—changes caused mostly by human activity—have reduced the food available and made it harder for the birds to reach. And so, since 1995, when B95 was first captured and banded, the worldwide rufa population has collapsed by nearly 80 percent. Most perish somewhere along the great hemispheric circuit, but the Moonbird wings on. He has been seen as recently as November 2011, which makes him nearly twenty years old. Shaking their heads, scientists ask themselves: How can this one bird make it year after year when so many others fall?  National Book Award–winning author Phillip Hoose takes us around the hemisphere with the world’s most celebrated shorebird, showing the obstacles rufa red knots face, introducing a worldwide team of scientists and conservationists trying to save them, and offering insights about what we can do to help shorebirds before it’s too late. Through prose, research, and images, Hoose explores the tragedy of extinction through the triumph of a single bird.
