  The media and politicians have been sounding the alarm for years, and with every fresh tragedy involving a young perpetrator comes another flurry of articles about the dangers of violent media. The problem is this: Their fear isn't supported by the evidence. In fact, unlike the video game–trained murder machines depicted in the press, school shooters are actually less likely to be interested in violent games than their peers. In reality, most well-adjusted children and teenagers play violent video games, all without ever exhibiting violent behavior in real life. What's more, spikes in sales of violent games actually correspond to decreased rates of violent crime.If that surprises you, you're not alone—the national dialogue on games and violence has been hopelessly biased. But that's beginning to change. Scholars are finding that not only are violent games not one of society's great evils, they may even be a force for good.In Moral Combat, Markey and Ferguson explore how video games—even the bloodiest—can have a positive impact on everything from social skills to stress, and may even make us more morally sensitive.

  CHARGE - Why Does Gravity Rule?

  Humans have long been aware of the electric and magnetic forces around us, and scientific investigation showed that the two are intimately connected as electromagnetism. Lightning shows how devastating electricity can be in nature, while humans learned to exploit the flow of negatively charged electrons that make up an electric current. In the early twentieth century, the experiments of Ernest Rutherford showed that at the heart of atoms lies a positively charged nucleus. The positive charge comes from protons. Atoms are neutral because the charges of the electron and proton cancel out.The charges of the proton and electron are opposite and equal, even though the proton is bigger. But why are they equal? This is one of the deepest unresolved puzzles of physics. Frank Close takes us on a journey into the quantum subatomic world of particles. He describes the strong and weak forces that operate alongside electromagnetism, the color and flavor charges, as well as the parallels between them, giving hints of a deeper unity. Seeking an answer to why matter is neutral brings us to fundamental forces and particles, the Standard Model, the Higgs boson, and implications of grand unification for the stability of matter. Close packs in a rich account of our current understanding and the latest ambitious experiments to probe further, and test theoretical possibilities.

  Recent years have seen out of control wildfires rage across remote Brazilian rainforests, densely populated California coastlines, and major cities in Australia. What connects these separate events is more than immediate devastation and human loss of life. In Global Burning, Eve Darian-Smith contends that using fire as a symbolic and literal thread connecting different places around the world allows us to better understand the parallel, and related, trends of the growth of authoritarian politics and climate crises and their interconnected global consequences.As political leaders and big business work together in the pursuit of profits and power, anti-environmentalism has become an essential political tool enabling the rise of extreme right governments and energizing their populist supporters. These are the governments that deny climate science, reject environmental protection laws, and foster exclusionary worldviews that exacerbate climate injustice.The widespread fires demand acknowledgment of the global systems of inequality that undergird them, connecting the political erosion of liberal democracy with the corrosion of the environment. In thinking through wildfires as environmental and political phenomenon, Global Burning challenges listeners to confront the interlocking powers that are ensuring our future ecological collapse.

  From jungles and rain forests to the driest deserts and barren arctic terrain, Planet Earth comprises a breathtaking array of ecosystems. As quickly becomes apparent, no one ecosystem exists independently of the rest, and no matter where a person resides, an understanding of all the ecosystems and how they work together as a living planet provides a better understanding of man's place on Earth and the future of the environment.
   
  In this series of lectures, renowned ornithologist John Kricher presents an absorbing analysis of the diverse ecosystems that exist on Planet Earth. He provides a factual study of the many fragile and threatened portions of our biosphere while describing the interaction between each system and the effect of man's presence in these ecosystems. Professor Kricher also explains the amazing variety of flora and fauna that inhabit the individual ecosystems and addresses current ecological issues facing mankind.

  This book contains 3 topics, all centered around astronomy: 
  1 - Cosmology: Welcome to a journey through the depths of space and time, a voyage into the heart of the cosmos, and an exploration of the most profound mysteries our universe holds. This is a book about cosmology—a science that unveils the grandeur of the universe, its history, its structure, and its deepest secrets. It's a journey through the vast expanses of space, where galaxies collide, stars are born and die, and black holes lurk in cosmic shadows. But it's also a journey through the frontiers of human knowledge and imagination, where the quantum world meets the cosmic expanse. 
  2 - Photometry: In the vast expanse of the universe, where the night sky reveals countless stars, planets, and galaxies, the pursuit of knowledge knows no bounds. Among the many tools at the disposal of astronomers and astrophysicists, photometry stands as a beacon of precision and insight. This book, "Photometry: Science, Sensitivity, and Its Connection to Astronomy," is your guided journey into the fascinating world of measuring and interpreting light in the cosmos. 
  3 - Spectroscopy: Spectroscopy, the study of the interaction between matter and electromagnetic radiation, may sound complex and esoteric, but at its heart lies a simple and profound idea: the colors of light can reveal the secrets of the universe. From the examination of distant stars to the analysis of molecules in a laboratory, spectroscopy is the key that unlocks the hidden stories encoded in light.

  The Elements We Live By - How...

  This “excellent” popular science book explores just what we—and the things around us—are made of (Aftenposten, Norway). 
   
  Some elements get all the attention: glittering gold, radioactive uranium—materials we call “precious” because they are so rare. But what could be more precious than the building blocks of life—from the oxygen in our air to the carbon in all living things? 
   
  In The Elements We Live By, physicist and award-winning author Anja Røyne reminds us that we’d be lost without the quiet heroes of the periodic table. Our bodies need phosphorous to hold our DNA together, potassium to power our optic nerves, and many more elements—in just the right amounts—to function. Other fundamental elements keep our technology (and society) running: Our phones contain arsenic, boron, and gallium to control signals and store information; indium and tin for the touch screen; and lithium for the battery. 
   
  Everything is made of elements—every galaxy, star, and planet—from the iron in Earth’s core to the silicon in its sand. But that doesn’t mean the elements we rely on will never run out; for example, about half the lithium we need is extracted from rocks in Australia, and the other half is from saltwater in Argentina and Chile. As Røyne travels the world to find where these elements exist (some in ever-shrinking amounts), she shows how vitally urgent it is for us to protect them—the elements of our very existence. 
   
  “Not just a discussion of basic chemistry, this is a volume that looks at the human impact on the planet and what we can learn from nature…Useful for science or sociology courses that address the various impacts of natural resource development or for popular science readers.” —School Library Journal
