Their work has uncovered a number of the universe’s more surprising secrets, and many believe further wonders remain hidden within the theory’s tangle of equations, waiting to be exposed. In this sweeping narrative of science and culture, astrophysicist Pedro Ferreira brings general relativity to life through the story of the brilliant physicists, mathematicians, and astronomers who have taken up its challenge. For these scientists, the theory has been both a treasure trove and an enigma, fueling a century of intellectual struggle and triumph.. Einstein’s theory, which explains the relationships among gravity, space, and time, is possibly the most perfect intellectual achievement of modern physics, yet studying it has always been a controversial endeavor. Relativists were the target of persecution in Hitler’s Germany, hounded in Stalin’s Russia, and disdained in 1950s America. Even today, PhD students are warned that specializing in general relativity will make them unemployable. Despite these pitfalls, general relativity has flourished, delivering key insights into our understanding of the origin of time and the evolution of all the stars and galaxies in the cosmos. Its adherents have revealed what lies at the farthest reaches of the universe, shed light on the smallest scales of existence, and explained how the fabric of reality emerges. Dark matter, dark energy, black holes, and string theory are all progeny of Einstein’s theory. We are in the midst of a momentous transformation in modern physics. As scientists look farther and more clearly into space than ever before, The Perfect Theory reveals the greater relevance of general relativity, showing us where it started, where it has led, and where it can still take us.

    When the seventh row of the periodic table of elements was completed in June 2016 with the addition of four final elements—nihonium, moscovium, tennessine, and oganesson—we at last could identify all the ingredients necessary to construct our world.In Elemental, chemist and science educator Tim James provides an informative, entertaining, and quirkily illustrated guide to the table that shows clearly how this abstract and seemingly jumbled graphic is relevant to our day-to-day lives.James tells the story of the periodic table from its ancient Greek roots, when you could count the number of elements humans were aware of on one hand, to the modern alchemists of the twentieth and twenty-first centuries who have used nuclear chemistry and physics to generate new elements and complete the periodic table. In addition to this, he answers questions such as: What is the chemical symbol for a human? What would happen if all of the elements were mixed together? Which liquid can teleport through walls? Why is the medieval dream of transmuting lead into gold now a reality?Whether you're studying the periodic table for the first time or are simply interested in the fundamental building blocks of the universe—from the core of the sun to the networks in your brain—Elemental is the perfect guide.

    Heroes are often defined as ordinary characters who get thrust into extraordinary circumstances, and through courage and a dash of luck, cement their place in history. Chosen as FDR’s fourth-term vice president for his well-praised work ethic, good judgment, and lack of enemies, Harry S. Truman was the prototypical ordinary man, still considered an obscure Missouri politician. That is, until he was shockingly thrust in over his head after FDR's sudden death. At the climactic moments of the Second World War, Truman had to play judge and jury during the founding of the United Nations, the Potsdam Conference, the Manhattan Project, the Nazi surrender, the liberation of concentration camps, and the decision to drop the bomb and end World War II. Tightly focused, meticulously researched, and using documents not available to previous biographers, The Accidental President escorts readers into the situation room with Truman during this tumultuous, history-making 120 days, when the stakes were high and the challenges even higher.

    It addresses the most interesting, gruesome, and earthshaking historical murders, the reasons for them, and their consequences. Prepare to be amazed by the daring and determination of the world’s most notorious criminals, and disturbed by the extremes taken by others to commit these crimes.As the saying goes, there is more than one way to skin a cat. The assassinators of history have proven to be inventive, even if not always effective. Read about the creative weapons, from pen guns to a pot of tea, and the various lengths taken to carry out their murderous acts. The book reveals what drives some individuals to commit assassinations, and ponders whether some deaths have been for the greater good. Fascinating paintings and photographs help bring this sinister human history to life.

    At the outset this group included the wives, sisters, and daughters of the resident astronomers, but soon the female corps included graduates of the new women's colleges--Vassar, Wellesley, and Smith. As photography transformed the practice of astronomy, the ladies turned from computation to studying the stars captured nightly on glass photographic plates.The "glass universe" of half a million plates that Harvard amassed over the ensuing decades--through the generous support of Mrs. Anna Palmer Draper, the widow of a pioneer in stellar photography--enabled the women to make extraordinary discoveries that attracted worldwide acclaim. They helped discern what stars were made of, divided the stars into meaningful categories for further research, and found a way to measure distances across space by starlight. Their ranks included Williamina Fleming, a Scottish woman originally hired as a maid who went on to identify ten novae and more than three hundred variable stars; Annie Jump Cannon, who designed a stellar classification system that was adopted by astronomers the world over and is still in use; and Dr. Cecilia Helena Payne, who in 1956 became the first ever woman professor of astronomy at Harvard--and Harvard's first female department chair.

    Houbolt, an unsung hero of Apollo 11 and the man who showed NASA how to put America on the moon. Without John C. Houbolt, a junior engineer at NASA, Apollo 11 would never have made it to the moon. Top NASA engineers on the project, including Werner Von Braun, strongly advocated for a single, huge spacecraft to travel to the moon, land, and return to Earth. It's the scenario used in 1950s cartoons and horror movies about traveling to outer space. Houbolt had another idea: Lunar Orbit Rendezvous. LOR would link two spacecraft in orbit while the crafts were travelling at 17,000 miles per hour. His plan was ridiculed and considered unthinkable. But this junior engineer was irrepressible. He stood by his concept, fired off memos to executives, and argued that LOR was the only way to success. For the 50th anniversary of Apollo 11, hear the untold story of the man who helped fulfill Kennedy’s challenge to reach the moon and begin exploring the final frontier.

    Croix. He went to America to pursue his education. Along the way he became one of the American Revolution’s most dashing—and unlikely—heroes. Adored by Washington, hated by Jefferson, Hamilton was a lightning rod: the most controversial leader of the American Revolution.She was the well-to-do daughter of one of New York’s most exalted families—feisty, adventurous, and loyal to a fault. When she met Alexander, she fell head over heels. She pursued him despite his illegitimacy, and loved him despite his infidelity. In 1816 (two centuries ago), she shamed Congress into supporting his seven orphaned children. Elizabeth Schuyler Hamilton started New York’s first orphanage. The only “founding mother” to truly embrace public service, she raised 160 children in addition to her own.With its flawless writing, brilliantly drawn characters, and epic scope, The Hamilton Affair will take its place among the greatest novels of American history.

    In Lower Manhattan, on a field in Pennsylvania, and along the banks of the Potomoc, the United States suffered the single largest loss of life from an enemy attack on its soil.In November 2002 the United States Congress and President George W. Bush established by law the National Commission on Terrorist Attacks Upon the United States, also known as the 9/11 Commission. This independent, bipartisan panel was directed to examine the facts and circumstances surrounding the September 11 attacks, identify lessons learned, and provide recommendations to safeguard against future acts of terrorism. This volume is the authorized edition of the Commission's final report. This volume is the authorized edition of the Commission's final report.

    What would happen to his life, his presidency, his country, his world?Now he presents his most compelling narrative of all about the historical event that has riveted us for fifty years. What if Kennedy were not killed that fateful day? What would the 1964 campaign have looked like? Would changes have been made to the ticket? How would Kennedy, in his second term, have approached Vietnam, civil rights, the Cold War? With Hoover as an enemy, would his indiscreet private life finally have become public? Would his health issues have become so severe as to literally cripple his presidency? And what small turns of fate in the days and years before Dallas might have kept him from ever reaching the White House in the first place?As with Then Everything Changed, the answers Greenfield provides and the scenarios he develops are startlingly realistic, rich in detail, shocking in their projections, but always deeply, remarkably plausible. It is a tour de force of American political history.

    And yet, until the explosive Trump presidency, few Americans could even name a member.“A must-read for anyone interested in how Washington really works” (Ivo H. Daalder), White House Warriors finally reveals how the NSC evolved from a handful of administrative clerks to, as one recent commander-in-chief called them, the president’s “personal band of warriors.”When Congress originally created the National Security Council in 1947, it was intended to better coordinate foreign policy after World War II. Nearly an afterthought, a small administrative staff was established to help keep its papers moving. President Kennedy was, as John Gans documents, the first to make what became known as the NSC staff his own, selectively hiring bright young aides to do his bidding during the disastrous Bay of Pigs operation, the fraught Cuban Missile Crisis, and the deepening Vietnam War.Despite Kennedy’s death and the tragic outcome of some of his decision, the NSC staff endured. President Richard Nixon handed the staff’s reigns solely to Henry Kissinger, who, given his controlling instincts, micromanaged its work on Vietnam. In the 1980s, President Ronald Reagan’s NSC was cast into turmoil by overreaching staff members who, led by Oliver North, nearly brought down a presidency in the Iran-Contra scandal. Later, when President George W. Bush’s administration was bitterly divided by the Iraq War, his NSC staff stepped forward to write a plan for the Surge in Iraq.Juxtaposing extensive archival research with new interviews, Gans demonstrates that knowing the NSC staff’s history and its war stories is the only way to truly understand American foreign policy. As this essential account builds to the swift removals of advisors General Michael Flynn and Steve Bannon in 2017, we see the staff’s influence in President Donald Trump’s still chaotic administration and come to understand the role it might play in its aftermath.A revelatory history written with riveting DC insider detail, White House Warriors traces the path that has led us to an era of American aggression abroad, debilitating fights within the government, and whispers about a deep state conspiring against the public.

    But conspiracy theories are becoming more popular and more widespread in the twenty-first century. Nowhere have they become more obvious than in revisionist accounts of the history of the Third Reich. Long-discredited conspiracy theories have taken on a new lease of life, given credence by claims of freshly discovered evidence and novel angles of investigation.In The Hitler Conspiracies renowned historian Richard Evans takes five widely discussed claims involving Hitler and the Nazis and subjects them to forensic scrutiny: that the Jews were conspiring to undermine civilization, as outlined in The Protocols of the Elders of Zion; that the German army was 'stabbed in the back' by socialists and Jews in 1918; that the Nazis burned down the Reichstag in order to seize power; that Rudolf Hess' flight to the UK in 1941 was sanctioned by Hitler and conveyed peace terms suppressed by Churchill; and that Hitler escaped the bunker in 1945 and fled to South America. In doing so, it teases out some surprising features that these, and other conspiracy theories, have in common.This is a history book, but it is a history book for the age of 'post-truth' and 'alternative facts': a book for our own troubled times.

    A vivid and eloquent book." --Stephen W. Sears, author of Gettysburg"Little Round Top has become iconic in Civil War literature and American memory. In the emotional recollection of our great war, if there was one speck on the landscape that decided a battle and the future of a nation, then surely this was it. The story of the July 2, 1863 struggle for that hill outside Gettysburg goes deeper into our consciousness than that, however. The men who fought for it then and there believed it to be decisive, and that is why they died for it. Glenn W. LaFantasie's Twilight at Little Round Top addresses that epic struggle, how those warriors felt then and later, and their physical and emotional attachment to a piece of ground that linked them forever with their nation's fate. This is military and social history at its finest." --W.C. Davis, author of Lincoln's Men and An Honorable Defeat"Few military episodes of the Civil War have attracted as much attention as the struggle for Little Round Top on the second day of Gettysburg. This judicious and engaging book navigates confidently through a welter of contradictory testimony to present a splendid account of the action. It also places events on Little Round Top, which often are exaggerated, within the broader sweep of the battle. All readers interested in the battle of Gettysburg will read this book with enjoyment and profit." --Gary W. Gallagher, author of The Confederate War"In his beautifully written narrative, Glenn LaFantasie tells the story of the battle for Little Round Top from the perspective of the soldiers who fought and died in July 1863. Using well-chosen quotes from a wide variety of battle participants, TWILIGHT puts the reader in the midst of the fight--firing from behind boulders with members of the 4th Alabama, running up the hillside into battle with the men of the 140th New York, and watching in horror as far too many men die. This book offers an elegy to the courage of those men, a meditation on the meaning of war, and a cautionary tale about the sacrifices nations ask of their soldiers and the causes for which those sacrifices are needed." --Amy Kinsel, Winnrer of the 1993 Allan Nevins Prize for From These Honored Dead: Gettysburg in American Culture
