FORENSIC ASPECTS of Arson and Explosives With one big bang, the universe exploded into being 13.7 million years ago. This is the story of how everything came about, from the moment when time and space came into existence, to the formation of the first stars, galaxies, and planets, to the evolution of human beings able to contemplate our own origins and ultimate destiny—and on to the infinite future, after the Red Giant Sun consumes Earth. Bang! explains it all in clear, straightforward terms, chronologically, without any mathematics, and including the most up-to-date discoveries.New in paperback. Stephen Hawking, one of the most brilliant theoretical physicists in history, wrote the modern classic A Brief History of Time to help non-scientists understand fundamental questions of physics and our existence: where did the universe come from? How and why did it begin? Will it come to an end, and if so, how?Hawking attempts to deal with these questions (and where we might look for answers) using a minimum of technical jargon. Among the topics gracefully covered are gravity, black holes, the Big Bang, the nature of time and physicists\' search for a grand unifying theory. This is deep science the concepts are so vast (or so tiny) that they cause mental vertigo while reading, and one can\'t help but marvel at Hawking\'s ability to synthesize this difficult subject for people not used to thinking about things like alternate dimensions. The journey is certainly worth taking for as Hawking says, the reward of understanding the universe may be a glimpse of “the mind of God”.(From Hawking dot org dot uk)A Brief History of Time, published in 1988, was a landmark volume in science writing and in world-wide acclaim and popularity, with more than 9 million copies in print globally. The original edition was on the cutting edge of what was then known about the origins and nature of the universe. But the ensuing years have seen extraordinary advances in the technology of observing both the micro- and the macrocosmic world—observations that have confirmed many of Hawking\'s theoretical predictions in the first edition of his book. Now a decade later, this edition updates the chapters throughout to document those advances, and also includes an entirely new chapter on Wormholes and Time Travel and a new introduction. It makes vividly clear why A Brief History of Time has transformed our view of the universe. (Refers to later editions) Big History is our modern scientific and historical creation story which unfolds in eight increasing thresholds of complexity. Our story starts with the creation of the Universe in the Big Bang, 13.8 billion years ago. Then we proceed to the formation of the first stars and galaxies, 200 million years after the Big Bang. The third threshold is the creation of all the chemical elements in the Universe, either within the core of stars, or for those elements heavier than iron, from exploding supernovas. This diversity of chemical elements allowed for greater complexity, the formation of gas, ice, and rocky planets, including our Earth and solar system, which was formed 4.5 billion years ago. The fifth threshold examines the appearance of life on Earth 3.8 billion years ago, and the incredible explosion of species through the process of natural selection and evolution. This evolution ultimately leads to the sixth threshold, humans, who first appeared in the Rift Valley of East Africa 300,000 years ago. We then explore the history of humanity from leaving Africa, migrating around the world as hunters and gatherers, and the advent of agriculture alongside major river systems around 12,000 years ago after the end of the last Ice Age, directly leading to great civilizations, the modern world, and our technological revolution, which we are just on the cusp of experiencing now. We examine the future of humanity, the Earth, solar system, our Milky Way galaxy, and ultimately the Universe. In this book, I argue that we are close to approaching a ninth level of increasing complexity, the singularity, when artificial intelligence will exceed human intelligence. The dramatic history of explosives, from the invention of gunpowder to the H-bomb Laying the emphasis on the lives of the people involved, on the diverse uses of explosives, and on their social and historical impact, this entertaining history relates a story of remarkable international and human endeavor. Many of those involved—Roger Bacon, Guy Fawkes, Alfred Nobel, Robert Oppenheimer—are famed worldwide others, such as C.F. Schonbein, William Bickford, Sir Frederick Abel, and Charles E. Munroe, though less well-known, also played critical roles. Alongside their achievements, this book highlights the uses and impact of explosives in both war and terrorism, and in civil engineering, quarrying, mining, demolition, fireworks manufacture, and shooting for sport. In many cases explosives are seen to have had a significant historical impact as, for example, in the early use of gunpowder in the Civil War, the defeat of the Spanish Armada, and the worldwide opening up of canals and railways.
