When most Americans think of slavery, they do not picture the colonial or revolutionary eras. Yet, in fact, one of six inhabitants of the thirteen original colonies was enslaved. The Escapes of David George: an Odyssey of Slavery, Freedom, and the American Revolution reveals a remarkable, untold experience of the American revolutionary period—a Black man's quest for the freedom espoused by our Founders, but denied him and other enslaved people.

Real wages have stagnated or declined for most workers, job insecurity has increased, and retirement income is uncertain. Why have jobs gotten so much worse? As Peter Cappelli argues, these issues and others stem from the logic of financial accounting and its fundamental flaws in dealing with human capital. Financial accounting views employee costs as fixed costs that cannot be reduced and fails to account for the costs of bad employees and poor management. The simple goal of today's executives is to drive down employment costs, even if it raises costs elsewhere.

Dr. Michael Baden has been involved in some of the most high-profile civil rights and police brutality cases in United States history, from the government's 1976 re-investigation of the assassination of Martin Luther King, Jr., to the 2014 death of Michael Brown, whose case sparked the initial Ferguson protests that grew into the Black Lives Matter movement. The playbook hasn't changed since 1979, when Dr. Baden was demoted from his job as New York City's Chief Medical Examiner after ruling that the death of a Black man in police custody was a homicide.

Mars, a mysterious dust-ridden place, is most like Earth in its climate and seasons. Of all the possible destinations in space to travel, Mars is the most likely for humans to reach. According to esteemed scientist Louis Friedman, it may be the only destination outside the moon to ever see human footprints. Far from diminishing our future in space, Human Spaceflight lays out a provocative future for human space travel. The noted aerospace engineer and scientist says that human space exploration will continue well into the future, but space travel by humans will stop at Mars.

Most Civil War battles took place along major roads, railroads, and waterways. And yet this perspective hasn't been fully explored when it comes to Gettysburg. Gettysburg Ranger and historian Troy Harman draws on a lifetime of researching the Civil War and more than thirty years of studying the terrain of Gettysburg and south-central Pennsylvania and northern Maryland to reframe the story of the Battle of Gettysburg.

The carbon dioxide that industrial civilization spews into the atmosphere has dramatic consequences for life on Earth that extend beyond climate change. CO2 levels directly affect plant growth, in turn affecting any kind of life that depends on plants—in other words, everything.

This book traces the lives of the Macaw and her enigmatic captain, from birth on San Francisco Bay to death at Midway. Ultimately, for Paul Burton and the Macaw the real enemy was the sea, and in a deadly denouement told here in riveting detail, the sea won. Highlighting the underreported role auxiliary vessels played in the war, A Strange Whim of the Sea should engage the military historian and layperson alike with the previously untold story it tells of struggle, sacrifice, death, and survival in the Pacific in World War II.

Revised, updated, and expanded with the latest interpretations and fossil discoveries, the second edition of Oceans of Kansas adds new twists to the fascinating story of the vast inland sea that engulfed central North America during the Age of Dinosaurs. Giant sharks, marine reptiles called mosasaurs, pteranodons, and birds with teeth all flourished in and around these shallow waters. Their abundant and well-preserved remains were sources of great excitement in the scientific community when first discovered in the 1860s and continue to yield exciting discoveries 150 years later.

Bibliophobia is a book about material books, how they are cared for, and how they are damaged, throughout the 5,000-year history of writing from Sumeria to the smartphone. A global history, covering six continents and seven religions, it discusses topics such as the origins of human script; the development of textual media such as scrolls, codices, printed books, and AI; the collection and destruction of libraries; the use of books as holy relics, talismans, or shrines; and the place of literacy in the history of slavery, heresy, blasphemy, censorship, and persecution.

In May 2018, NASA called a press conference to announce the successful test-run of their tiny nuclear reactor KRUSTY (Kilopower Reactor Using Stirling Technology). This revolutionary technology, which runs on heat alone, may have profound consequences for the future of mankind, enabling us to maintain permanent bases on the Moon, on Mars, and other planets, and eventually power a starship. On earth too it could have enormous benefits as a new way to generate power at a time when climate change is threatening our very existence.

When Jefferson acquired the Louisiana Territory, he envisioned an "empire for liberty" populated by self-sufficient white farmers. Cleared of Native Americans and the remnants of European empires by Andrew Jackson, the Mississippi Valley was transformed instead into a booming capitalist economy commanded by wealthy planters, powered by steam engines, and dependent on the coerced labor of slaves.

Levels of violent crime have been in a steady decline for centuries-for millennia, even. Over the past 500 years, homicide rates have decreased a hundred-fold. We live in a time that is more orderly and peaceful than ever before in human history. Why, then, does fear of crime dominate modern politics? In Command and Persuade, Peter Baldwin examines the evolution of the state's role in crime and punishment over 3,000 years.

Sixteen sparkling episodes of the iconic comedy panel show Radio 4's longest-running panel game returns for the first time since the death of much-missed maestro Nicholas Parsons, who chaired the show for over 50 years. Following in his footsteps for Series 86 are an array of special guest hosts...

Today, Germantown is a busy neighborhood in Philadelphia. On October 4, 1777, it was a small village on the outskirts of the colonial capital whose surrounding fields and streets witnessed one of the largest battles of the American Revolution. The bloody battle represented George Washington's attempt to recapture Philadelphia but has long been overshadowed by better-known events like Brandywine, Saratoga, and Valley Forge.

Well over 100 years ago the data industry put in place a business model that trades our attention for news and entertainment. That model has evolved into a complex art and science of message targeting and content ownership that has splintered communities while simultaneously concentrating media ownership to a few massive corporations. Forged in War takes a critical look at the systems we use and how we ended up in a society that values data over personal liberty and commerce over the public good.

From the beginning, American cinema has been both a powerful mythmaker and a social critic. D.W. Griffith's Birth of a Nation, arguably the first feature film, shows us just how early in its history cinema had established its influence. Birth of a Nation famously portrayed the Ku Klux Klan in a favorable light, a portrayal that contributed to the modern resurgence of the group and brought racist depictions of African Americans imported from the minstrel show to the silver screen. In response, filmmakers of color have created nuanced and indelible portraits of race.

During his years as a public official, Mitchell Weiss was told that government can't do new things or solve tough challenges - it's too big and slow and bureaucratic. Sadly, this is what so many of us have come to believe. But in the wake of the Boston Marathon bombings, he and his city hall colleagues raced to support survivors in new, innovative ways. This kind of entrepreneurial spirit and savvy in government is growing, transforming the public sector's response to big problems at all levels.

The Education of John Adams is the first biography of John Adams by a biographer with legal training. It examines his origins in colonial Massachusetts, his education, and his struggle to choose a career and define a place for himself in colonial society.

President Franklin D. Roosevelt organized an extraordinary partnership between the US government and America's media outlets to communicate to the reluctant and isolationist American public the nature of the threat that World War II posed to the nation and the world. The coalition's aim was to promote the concept of American exceptionalism and use it to galvanize the public for the government's cause.
