This book includes: -Details about the ancient civilizations that once existed around the world and the events which led to their disappearance. -Translations from ancient texts that include: The Atrahasis, Enuma Elish, Sumerian King List, Eridu Genesis, Code of Hammurabi, Emerald Tablets, and more. -The eagle and the serpent, cataclysms during the last ice age, and the influences of the Anunnaki. -Secrets of consciousness, reincarnation, spirituality, and sentient life in the universe.

     This book is a supplement to What If? and intended to enhance the experience of reading the original book. We recommend purchasing the full version of What If? on Amazon in addition to this book. Introduction What If? Serious Scientific Answers to Absurd Hypothetical Questions presents a wide variety of questions covering a range of dubious potentialities and the results which would ensue should they become reality. The questions are collected from author Randall Munroe’s website, where they are sent in by readers of his blog. Some of the questions are conceptual, for example how much force would be required for Yoda to lift an X-fighter, others are in a more serious vein. All of the answers however are based on research and the application of scientific principles by the author, himself trained in physics and a former roboticist for NASA.

    Men like Andrew Carnegie built empires like Carnegie Steel, and financiers like J.P. Morgan merged and consolidated them. The era also made names like Astor, Cooke, and Vanderbilt instantly recognizable across the globe. Over time, the unfathomable wealth generated by the businesses made the individuals on top incredibly rich, and that in turn led to immense criticism and an infamous epithet used to rail against them: robber barons. Dozens of men were called “robber barons”, but few of them were as notorious as Cornelius Vanderbilt, who also happened to be one of the nation’s first business titans. Vanderbilt was a railroad and shipping magnate at a time that the industry was almost brand new, but he rode his success to become one of the richest and most powerful men in American history. When historians are asked to name the richest man in history, a name that often pops up is that of John D. Rockefeller, who co-founded Standard Oil and turned it into the first real trust in the United States. Rockefeller had been groomed ambitiously by a huckster father nicknamed “Devil Bill”, who was just as willing to cheat his son as an unsuspecting public, and John certainly chased his dreams of living long and large. Rockefeller forged his empire in the first few decades of his life and nearly worked himself to death by the time he was 50, which helped compel him to retire for the last several decades of his life. At one point, Rockefeller’s wealth was worth more than 1.5% of the entire country’s gross domestic product, and by adjusting for inflation, he is arguably the richest man in American history if not world history. When robber barons across America took the reins of vast industries, they needed financing, and many of them turned to the most famous banker of all: John Pierpont Morgan. It was J.P. Morgan who bankrolled the consolidation of behemoth corporations across various industries, including the merging of Edison General Electric and Thomson-Houston Electric Company, which subsequently became General Electric, still known simply as GE across the world today. Similarly, he financed Federal Steel Company and consolidated various other steel businesses to help form the United States Steel Corporation. While critics complained about the outsized influence that these gigantic businesses had, Morgan’s massive wealth also gave him unprecedented power in the financial sector and the ability to deal with politicians. In fact, Morgan played an important part in the Panic of 1907 and the subsequent decision to create the Federal Reserve as a monetary oversight. Ironically, one of America’s most famous robber barons, Andrew Carnegie, epitomized the American Dream, migrating with his poor family to America in the mid-19th century and rising to the top of the business world in his adopted country. A prodigious writer in addition to his keen sense of business, Carnegie was one of the most outspoken champions of capitalism at a time when there was pushback among lower social classes who witnessed the great disparities in wealth; as he once put it, “Upon the sacredness of property civilization itself depends—the right of the laborer to his hundred dollars in the savings bank, and equally the legal right of the millionaire to his millions.

    The biological background provided enables students to comprehend the major problems in biochemical engineering and formulate effective solutions.

    The First seven chapters deal with structure related aspects such as lattice and crystal structures, bonding, packing and diffusion of atoms followed by imperfections and lattice vibrations. Chapter eight deals mainly with experimental methods of determining structures of given materials. While the next nine chapters cover various physical properties of crystalline solids, the last chapter deals with the anisotropic properties of materials. This chapter has been added for benefit of readers to understand the crystal properties (anisotropic) in terms of some simple mathematical formulations such as tensor and matrix. New to the Second Edition: Chapter on: *Anisotropic Properties of Materials

    If these galaxies had always been travelling, he reasoned, then they must, at some point, have been on top of one another. This discovery transformed the debate about one of the most fundamental questions of human existence - how did the universe begin?Every society has stories about the origin of the cosmos and its inhabitants, but now, with the power to peer into the early universe and deploy the knowledge gleaned from archaeology, geology, evolutionary biology and cosmology, we are closer than ever to understanding where it all came from. In The Origin of (almost) Everything, New Scientist explores the modern origin stories of everything from the Big Bang, meteorites and dark energy, to dinosaurs, civilisation, timekeeping, belly-button fluff and beyond.From how complex life evolved on Earth, to the first written language, to how humans conquered space, The Origin of (almost) Everything offers a unique history of the past, present and future of our universe.span

    He spent two years gathering information that demonstrates this and along the way interviewed more than a hundred experts in a number of different fields. Among them were parapsychologists, medical doctors, psychologists, psychiatrists, quantum physicists, and researchers into the true nature of reality. Specific examples are presented that indicate what happens when we die, for example that memories can be formed and retained despite a subject’s brain having been shutdown and the blood drained from it. Questions such as whether or not you will be able to communicate with living loved ones after death are addressed, if it is possible to be reborn, and what might be missing from reproductive theory to explain the various phenomena indicated in the many case histories and scientific investigations presented. All of us will someday cross the border to what Shakespeare called "The undiscovered country." As long as we must make that trip, wouldn’t it be smart to find out where we are going and what to expect when we get there?
