Twentieth-century developments such as quantum mechanics are introduced early on, so that students can appreciate their importance and see how they fit into the bigger picture.

    - This is the best kind of popular science: informed, impassioned, and highly accessible.- Compare it to Stephen Hawking's The Universe in a Nutshell, but broader in scope and much more readable.- A crossover for the Young Adult market, now in the perfect format.

    They found him a dreamy child without an especially promising future. But some time in his early years he developed what he called wonder about the world. Later in life, he remembered two instances from his childhood--his fascination at age five with a compass and his introduction to the lucidity and certainty of geometry--that may have been the first signs of what was to come. From these ordinary beginnings, Einstein became one of the greatest scientific thinkers of all time. This illuminating biography describes in understandable language the experiments and revolutionary theories that flowed from Einstein's imagination and intellect--from his theory of relativity, which changed our conception of the universe and our place in it, to his search for a unified field theory that would explain all of the forces in the universe.

    Through metaphors and straightforward language, it breathes life into astrophysics, unveiling how particles and forces and fields interplay to create the drama in the heavens above us.

    It is now revised to reflect the most recent advances in physics. From black holes to holograms, from relativity theory to the discovery of quarks, this book is an original and rich exposition of quantum theory and the way it unravels profound theological questions.

    He decried the internment of Japanese-Americans in World War Two, agitated against nuclear weapons, promoted vitamin C as a cure for the common cold and researched the idea of DNA.

    In those twelve months, Einstein shattered many cherished scientific beliefs with five extraordinary papers that would establish him as the world's leading physicist. This book brings those papers together in an accessible format. The best-known papers are the two that founded special relativity: On the Electrodynamics of Moving Bodies and Does the Inertia of a Body Depend on Its Energy Content? In the former, Einstein showed that absolute time had to be replaced by a new absolute: the speed of light. In the second, he asserted the equivalence of mass and energy, which would lead to the famous formula E = mc2.The book also includes On a Heuristic Point of View Concerning the Production and Transformation of Light, in which Einstein challenged the wave theory of light, suggesting that light could also be regarded as a collection of particles. This helped to open the door to a whole new world--that of quantum physics. For ideas in this paper, he won the Nobel Prize in 1921.The fourth paper also led to a Nobel Prize, although for another scientist, Jean Perrin. On the Movement of Small Particles Suspended in Stationary Liquids Required by the Molecular-Kinetic Theory of Heat concerns the Brownian motion of such particles. With profound insight, Einstein blended ideas from kinetic theory and classical hydrodynamics to derive an equation for the mean free path of such particles as a function of the time, which Perrin confirmed experimentally. The fifth paper, A New Determination of Molecular Dimensions, was Einstein's doctoral dissertation, and remains among his most cited articles. It shows how to calculate Avogadro's number and the size of molecules.These papers, presented in a modern English translation, are essential reading for any physicist, mathematician, or astrophysicist. Far more than just a collection of scientific articles, this book presents work that is among the high points of human achievement and marks a watershed in the history of science. Coinciding with the 100th anniversary of the miraculous year, this new paperback edition includes an introduction by John Stachel, which focuses on the personal aspects of Einstein's youth that facilitated and led up to the miraculous year.

    There's a lot for astronomers to be smug about. But when it comes to understanding how the Universe began and grew up we are literally in the dark ages. In effect, we are missing the first one billion years from the timeline of the Universe.This brief but far-reaching period in the Universe's history, known to astrophysicists as the 'Epoch of Reionisation', represents the start of the cosmos as we experience it today. The time when the very first stars burst into life, when darkness gave way to light. After hundreds of millions of years of dark, uneventful expansion, one by the one these stars suddenly came into being. This was the point at which the chaos of the Big Bang first began to yield to the order of galaxies, black holes and stars, kick-starting the pathway to planets, to comets, to moons, and to life itself.Incorporating the very latest research into this branch of astrophysics, this book sheds light on this time of darkness, telling the story of these first stars, hundreds of times the size of the Sun and a million times brighter, lonely giants that lived fast and died young in powerful explosions that seeded the Universe with the heavy elements that we are made of. Emma Chapman tells us how these stars formed, why they were so unusual, and what they can teach us about the Universe today. She also offers a first-hand look at the immense telescopes about to come on line to peer into the past, searching for the echoes and footprints of these stars, to take this period in the Universe's history from the realm of theoretical physics towards the wonder of observational astronomy.

    And from the Deepwater Horizon oil disaster to Hurricane Katrina, he’s shown an astounding ability to beat the odds (and beat the bureaucrats) to get things done.Then again, Jindal is not your typical politician. The son of Indian immigrants, a Christian convert from Hinduism, and a Rhodes Scholar, Jindal presided over Louisiana’s healthcare system at age 24, headed the University of Louisiana system at 27, became a U.S. congressman at 33, and was elected governor of Louisiana at 36.Throughout his meteoric career, Jindal has dealt with some of the worst crises of our times, from natural disasters in his home state to out-of-control spending in Washington, D.C. His secret: the common sense solutions that bureaucrats (and politicians) ignore in favor of government–as–usual.In Leadership and Crisis, Jindal reveals: How the Obama administration spent too much time worrying about public perception and not enough on actually fighting the oil How the federal government actually impeded Louisiana’s efforts to stem the flood of oil Why the bureaucratic incompetence during Hurricane Katrina was even worse than you know How Bobby Jindal took on Louisiana’s infamous culture of corruption His own journey from Hinduism to Christianity, from student at Oxford to Governor of Louisiana, from policy wonk to instant midwife when he had to deliver his third child himself Filled with behind–the–scenes stories from the oil–slicked beaches of Louisiana to the corridors of power in the U.S. Capitol, Leadership and Crisis offers an insider’s view into one of the worst environmental disasters our nation has suffered—and into one of the most unique success stories of American politics.
