Horizons of Heroes 2: The Next Twenty Years
Par Cameron Price. 2017
After returning from the Vietnam War, Cameron finds the United States has changed in ways he could not have imagined.…
He struggles to find his path through challenges in relationships, school, and employment. As an African American in the early 1970s, Cameron learns he must persevere a great deal more than the average person in order to achieve his goals and dreams. As one of the former highest ranking spies in the military, Cameron dares to share his view on how women know if it is “real love.” Horizons of Heroes: The Next Twenty Years is an amazing non-fiction book and an excellent read.Solar Power Satellites
Par Don M. Flournoy. 2012
Communication satellites are a $144 billion industry. Is there any space-based industry that could possibly beat that market? 'Solar Power…
Satellites' shows why and how the space satellite industry will soon begin expanding its market from relaying signals to Earth to generating energy in space and delivering it to the ground as electricity. In all industrialized nations, energy demand is growing exponentially. In the developing world, the need for energy is as basic as food and water. The Sun's energy is available everywhere, and it is non-polluting. As business plans demonstrate its technical feasibility, commercial potential, and environmental acceptability, every country on Earth will look to space for the power it needs.When the fuzzy indeterminacy of quantum mechanics overthrew the orderly world of Isaac Newton, Albert Einstein and Erwin Schrödinger were…
at the forefront of the revolution. Neither man was ever satisfied with the standard interpretation of quantum mechanics, however, and both rebelled against what they considered the most preposterous aspect of quantum mechanics: its randomness. Einstein famously quipped that God does not play dice with the universe, and Schrödinger constructed his famous fable of a cat that was neither alive nor dead not to explain quantum mechanics but to highlight the apparent absurdity of a theory gone wrong. But these two giants did more than just criticize: they fought back, seeking a Theory of Everything that would make the universe seem sensible again. In Einstein’s Dice and Schrödinger’s Cat, physicist Paul Halpern tells the little-known story of how Einstein and Schrödinger searched, first as collaborators and then as competitors, for a theory that transcended quantum weirdness. This story of their quest--which ultimately failed--provides readers with new insights into the history of physics and the lives and work of two scientists whose obsessions drove its progress. Today, much of modern physics remains focused on the search for a Theory of Everything. As Halpern explains, the recent discovery of the Higgs Boson makes the Standard Model--the closest thing we have to a unified theory-- nearly complete. And while Einstein and Schrödinger failed in their attempt to explain everything in the cosmos through pure geometry, the development of string theory has, in its own quantum way, brought this idea back into vogue. As in so many things, even when they were wrong, Einstein and Schrödinger couldn’t help but get a great deal right.Quantum Mechanics: The Theoretical Minimum (The Theoretical Minimum)

is a (second) book for anyone who wants to learn how to think like a physicist. In this follow-up to the bestselling The Theoretical Minimum, physicist Leonard Susskind and data engineer Art Friedman offer a first course in the theory and associated mathematics of the strange world of quantum mechanics. Quantum Mechanics presents Susskind and Friedman's crystal-clear explanations of the principles of quantum states, uncertainty and time dependence, entanglement, and particle and wave states, among other topics. An accessible but rigorous introduction to a famously difficult topic, Quantum Mechanics provides a tool kit for amateur scientists to learn physics at their own pace.Modern Techniques of Surface Science
Par D. Phil, Woodruff. 2016
This is a fully revised and expanded edition of a very successful and widely used book. It describes the physical…
basis of all the principal, and most of the more specialised, techniques currently employed in the study of well-characterised solid surfaces. The coverage of each technique, illustrated with selected examples, is underpinned by discussion of the relevant physical principles, and the complementary aspects of the various methods are also described. Throughout, the emphasis is on understanding the concepts involved, rather than on an exhaustive review of applications. The book will be of great use to final year undergraduate and postgraduate students in physics, chemistry and materials science. It will also be valuable to established researchers in any area of surface science concerned with the acquisition and analysis of experimental data.Born to Battle: Grant and Forrest--Shiloh, Vicksburg, and Chattanooga
Par Jack Hurst. 2012
Born to Battleexamines the Civil War’s complex and decisive western theater through the exploits of its greatest figures, Ulysses S.…
Grant and Nathan Bedford Forrest. These two opposing giants squared off in some of the most epic campaigns of the war, starting at Shiloh and continuing through Perryville, Vicksburg, Chickamauga, and Chattanoogabattles in which the Union would slowly but surely divide the western Confederacy, setting the stage for the final showdowns of the bloody, protracted conflict. Grant is widely regarded as the man most responsible for winning the war for the Union, Forrest as the Confederacy’s most fearsome defender in the West. Both men had risen through their respective hierarchies thanks to their cunning and military brilliance, and despite their checkered pasts. Grant and Forrest were both lower”-born officers who struggled to overcome particular, dubious reputations (Forrest’s as a semi-literate rustic and Grant’s as a doltish drunkard). In time, however each became renowned for his intelligence, resourcefulness, and grit. Indeed, as Hurst shows, their familiarity with hardship gave both men a back-against-the-wall mindset that would ultimately determine their successboth on the battlefield, and off it. Beginning with the Union victory at Tennessee’s Fort Donelson in February 1862 (when Grant handed the Union the largest force ever captured on American soil, refurbishing his reputation and earning himself the nickname Unconditional Surrender Grant”), Hurst follows both men through the campaigns of the next twenty months, showing how this critical periodand these two unequaled leaderswould change the course of the war. Again and again, Grant’s hardscrabble tactics saved Federal forces from the disastrous decisions of his fellow commanders, who seemed unable to think outside of the West Point playbook. Just as often, Forrest’s hot temper and wily, frontier know-how would surprise his Federal adversaries and allow him to claim astonishing victories on behalf of the Confederacy. But as Grant pressed south and east over the course of these twenty months, routing Confederate forces at such critical strongholds as Corinth, Vicksburg (Gibraltar of the Mississippi”), and Chattanooga, the systemic differences between the North and South began to tell. The more inclusive, meritocratic Union allowed Grant to enter into the military’s halls of decision, whereas the proudly aristocratic Confederate high command barred Forrest from contributing his input. As Hurst vividly demonstrates, that disparity affected, and possibly dictated, the war’s outcome. Thoroughly disgusted with his disdainful superiors and their failure to save his home state of Tennessee from the clutches of the Union, Forrest eventually requested a transfer to a backwater theater of the war. Grant, by contrast, won command of the entire Union army following his troops’ stunning performance at Chattanooga, and would go on to lead the North to victory over the forces of another exceptional Southern general: Robert E. Lee. An utterly American tale about class, merit, and their role in one of the most formative wars in the nation’s history,Born to Battleoffers an impassioned account of two visionary Civil War leaders and the clashing cultures they foughtin some cases, quite ironicallyto protect. Hurst shows how Grant and Forrest brought to the battlefield the fabled virtues of the American working-class: hard work, ingenuity, and intense determination. Each man’s background contributed to his triumphs on the battlefield, but the open-mindedness of his fellow commanders proved just as important. When the North embraced Grant, it won a stalwart defender. When the South rejected Forrest, by contrast, it sealed its fate.Magnitude: The Scale of the Universe
Par Megan Watzke, Kimberly Arcand. 2017
In the tradition of illustrated science bestsellers, like Thing Explainer and harkening back to the classic film The Powers of…
Ten, this unique, fully-illustrated, four-color book explores and visualizes the concept of scale in our universe. In Magnitude, Kimberly Arcand and Megan Watzke take us on an expansive journey to the limits of size, mass, distance, time, temperature in our universe, from the tiniest particle within the structure of an atom to the most massive galaxy in the universe; from the speed at which grass grows (about 2 to 6 inches a month) to the speed of light. Fully-illustrated with four-color drawings and infographics throughout and organized into sections including Size and Amount (Distance, Area, Volume, Mass, Time, Temperature), Motion and Rate (Speed, Acceleration, Density, Rotation), and Phenomena and Processes (Energy, Pressure, Sound, Wind, Computation), Magnitude shows us the scale of our world in a clear, visual way that our relatively medium-sized human brains can easily understand.Six Not-So-Easy Pieces: Einstein's Relativity, Symmetry, and Space-Time

Par Roberto Trotta. 2014
From the big bang to black holes, from dark matter to dark energy, from the origins of the universe to…
its ultimate destiny, The Edge of the Sky tells the story of the most important discoveries and mysteries in modern cosmology#151;with a twist. The book’s lexicon is limited to the thousand most common words in the English language, excluding physics, energy, galaxy, or even universe. Through the eyes of a fictional scientist (Student-People) hunting for dark matter with one of the biggest telescopes (Big-Seers) on Earth (Home-World), cosmologist Roberto Trotta explores the most important ideas about our universe (All-there-is) in language simple enough for anyone to understand. A unique blend of literary experimentation and science popularization, this delightful book is a perfect gift for any aspiring astronomer. The Edge of the Sky tells the story of the universe on a human scale, and the result is out of this world.This monograph identifies the essential characteristics of the objects described by current quantum theory and considers their relationship to space-time.…
In the process, it explicates the senses in which quantum objects may be consistently considered to have parts of which they may be composed or into which they may be decomposed. The book also demonstrates the degree to which reduction is possible in quantum mechanics, showing it to be related to the objective indefiniteness of quantum properties and the strong non-local correlations that can occur between the physical quantities of quantum subsystems. Careful attention is paid to the relationships among such property correlations, physical causation, probability, and symmetry in quantum theory. In this way, the text identifies and clarifies the conceptual grounds underlying the unique nature of many quantum phenomena.How to Destroy the Universe

Par Shing-Tung Yau, Steve Nadis. 2010
String theory says we live in a ten-dimensional universe, but that only four are accessible to our everyday senses. According…
to theorists, the missing six are curled up in bizarre structures known as Calabi-Yau manifolds. In The Shape of Inner Space, Shing-Tung Yau, the man who mathematically proved that these manifolds exist, argues that not only is geometry fundamental to string theory, it is also fundamental to the very nature of our universe.Time and again, where Yau has gone, physics has followed. Now for the first time, readers will follow Yau's penetrating thinking on where we've been, and where mathematics will take us next. A fascinating exploration of a world we are only just beginning to grasp, The Shape of Inner Space will change the way we consider the universe on both its grandest and smallest scales.Cosmic Numbers: The Numbers That Define Our Universe

zones. Now Lewis brings his first-rate narrative skills to bear on the inspiriting tale of Judy--an English pointer who perhaps was the only canine prisoner of war. After being bombed and shipwrecked repeatedly while serving for several wild and war-torn years as a mascot of the World War II Royal Navy Yangtze river gunboats the Gnat and the Grasshopper, Judy ended up in Japanese prisoner of war camps in North Sumatra. Along with locals as slave labor, the American, Australian, and British POWs were forced to build a 1,200-mile single-track railroad through the most horrifying jungles and treacherous mountain passes. Like the one immortalized in the film The Bridge on the River Kwai, this was the other death-railroad building project where POWs slaved under subhuman conditions. In the midst of this living hell was a beautiful and regal-looking liver and white English pointer named Judy. Whether she was scavenging food to help feed the starving inmates of a hellish Japanese POW camp, or by her presence alone bringing inspiration and hope to men, she was cherished and adored by the Allied servicemen who fought to survive alongside her. Judy's uncanny ability to sense danger, matched with her quick thinking and impossible daring saved countless lives. More than a close companion she shared in both the men's tragedies and joys. It was in recognition of the extraordinary friendship and protection she offered amidst the unforgiving and savage environment of a Japanese prison camp in Indonesia that she gained her formal status as a POW. From the author of The Dog Who Could Fly and the co-author of Sergeant Rex and It's All About Treo comes one of the most heartwarming and inspiring tales you will ever read.The End of Pink

taxidermied mermaids, snake oil salesmen, and Benjamin Franklin--all from the annals of science and pseudoscience. Equal parts fact and folklore, these poems look to the marvelous and the weird for a way to understand childbirth, parenthood, sickness, death, and-of course--joy.Interpreting Physics
Par Edward Mackinnon. 2011
This book is the first to offer a systematic account of the role of language in the development and interpretation…
of physics. An historical-conceptual analysis of the co-evolution of mathematical and physical concepts leads to the classical/quatum interface. Bohrian orthodoxy stresses the indispensability of classical concepts and the functional role of mathematics. This book analyses ways of extending, and then going beyond this orthodoxy orthodoxy. Finally, the book analyzes how a revised interpretation of physics impacts on basic philosophical issues: conceptual revolutions, realism, and reductionism.The Craft of Scientific Writing
