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 discovery of two remarkably well preserved, two-million-year-old fossils of an adult female and young male, known as Australopiitecus sediba, has been hailed as one of the most important archaeological discoveries in history. The fossils reveal what may be one of humankind's oldest ancestors.Berger believes the skeletons they found on the Malapa site in South Africa could be the "Rosetta stone that unlocks our understanding of the genus Homo" and may just redesign the human family tree.Berger, an Eagle Scout and National Geographic Grantee, is the Reader in Human Evolution and the Public Understanding of Science in the Institute for Human Evolution at the University of Witwatersrand, Johannesburg, South Africa.The focus of the book will be on the way in which we can apply new thinking to familiar material and come up with a breakthrough. Marc Aronson is particularly interested in framing these issues for young people and has had enormous success with this approach in his previous books: Ain't Nothing But a Man and If Stones Could Speak.Berger's discovery in one of the most excavated and studied areas on Earth revealed a treasure trove of human fossils--and an entirely new human species--where people thought no more field work might ever be necessary. Technology and revelation combined, plus a good does of luck, to broaden by ten times the number of early human fossils known, rejuvenating this field of study and posing countless more questions to be answered in years and decades to come.

    A full-color chapter book biography that shows how a self-taught scientist was the first to observe the microbial life in and around us. By building his own microscope, Antony van Leeuwenhoek advanced humanity's understanding of our oft-invisible world around us.

    He envisioned something else: a multi-racial, urbanized, capitalistic America with a strong central government. He believed that such an America would be a land of opportunity for the poor and the newcomers. But Hamilton's vision put him at odds with his archrivals who envisioned a pastoral America of small towns, where governments were local, states would control their own destiny, and the federal government would remain small and weak. The disputes that arose during America's first decades continued through American history to our present day. Over time, because of the systems Hamilton set up and the ideas he left, his vision won out. Here is the story that epitomizes the American dream-a poor immigrant who made good in America. In the end, Hamilton rose from poverty through his intelligence and ability and did more to shape our country than any of his contemporaries.

    Butterflies can't survive cold weather, so when winter comes, many butterflies fly to warmer places. They migrate. Woodchucks don't like cold weather either but they don't migrate; they hibernate. Woodchucks sleep in their dens all winter long. Read and find out how other animals cope with winter's worst weather. This is a Level One Let’s-Read-and-Find-Out Science title, which means the book explores more challenging concepts for children in the primary grades and supports the Common Core Learning Standards, Next Generation Science Standards, and the Science, Technology, Engineering, and Math (STEM) standards. Let’s-Read-and-Find-Out is the winner of the American Association for the Advancement of Science/Subaru Science Books & Films Prize for Outstanding Science Series.

    Kaku skillfully guides us through the latest innovations in string theory and its latest iteration, M-theory, which posits that our universe may be just one in an endless multiverse, a singular bubble floating in a sea of infinite bubble universes. If M-theory is proven correct, we may perhaps finally find answer to the question, “What happened before the big bang?” This is an exciting and unforgettable introduction into the new cutting-edge theories of physics and cosmology from one of the pre-eminent voices in the field.

    Beneath the frozen crusts of several of the small, ice-covered moons of Jupiter and Saturn lurk vast oceans that may have been in existence for as long as Earth, and together may contain more than fifty times its total volume of liquid water. Could there be organisms living in their depths? Alien Oceans reveals the science behind the thrilling quest to find out.Kevin Peter Hand is one of today's leading NASA scientists, and his pioneering research has taken him on expeditions around the world. In this captivating account of scientific discovery, he brings together insights from planetary science, biology, and the adventures of scientists like himself to explain how we know that oceans exist within moons of the outer solar system, like Europa, Titan, and Enceladus. He shows how the exploration of Earth's oceans is informing our understanding of the potential habitability of these icy moons, and draws lessons from what we have learned about the origins of life on our own planet to consider how life could arise on these distant worlds.Alien Oceans describes what lies ahead in our search for life in our solar system and beyond, setting the stage for the transformative discoveries that may await us.
