Book Description
In the pantheon of air power spokesmen, Giulio Douhet holds center stage. His writings, more often cited than perhaps actually read, appear as excerpts and aphorisms in the writings of numerous other air power spokesmen, advocates-and critics. Though a highly controversial figure, the very controversy that surrounds him offers to us a testimonial of the value and depth of his work, and the need for airmen today to become familiar with his thought. The progressive development of air power to the point where, today, it is more correct to refer to aerospace power has not outdated the notions of Douhet in the slightest In fact, in many ways, the kinds of technological capabilities that we enjoy as a global air power provider attest to the breadth of his vision. Douhet, together with Hugh “Boom” Trenchard of Great Britain and William “Billy” Mitchell of the United States, is justly recognized as one of the three great spokesmen of the early air power era. This reprint is offered in the spirit of continuing the dialogue that Douhet himself so perceptively began with the first edition of this book, published in 1921. Readers may well find much that they disagree with in this book, but also much that is of enduring value. The vital necessity of Douhet’s central vision-that command of the air is all important in modern warfare-has been proven throughout the history of wars in this century, from the fighting over the Somme to the air war over Kuwait and Iraq.

Book Description
A timeless classic of economic theory that remains fascinating and pertinent today, this is Frank Knight's famous explanation of why perfect competition cannot eliminate profits, the important differences between "risk" and "uncertainty," and the vital role of the entrepreneur in profitmaking. Based on Knight's PhD dissertation, this 1921 work, balancing theory with fact to come to stunning insights, is a distinct pleasure to read. FRANK H. KNIGHT (1885-1972) is considered by some the greatest American scholar of economics of the 20th century. An economics professor at the University of Chicago from 1927 until 1955, he was one of the founders of the Chicago school of economics, which influenced Milton Friedman and George Stigler.

Book Description
This is the first edition of Charles Darwin's On the Origin of Species, published on November 24, 1859 in London by John Murray. It is a seminal work in scientific literature and a landmark work in evolutionary biology. It introduced the theory that populations evolve over the course of generations through a process of natural selection. It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. The starting chapters introduce the theory of natural selection, explaining why certain species thrive, while others decrease in number, how the members of nature are in competition with each other and why organisms tend to vary and change with time. Much of this work is based on experiments and observations seen within domestic animals and plants. The later chapters defend the theory of natural selection against apparent inconsistencies, why geological records are incomplete, why we find species so widespread and how sterility can be inherited when the organisation is unable to reproduce and more. The book is approachable for any audience.

Book Description
A powerful and impassioned historical account of the largest successful revolt by enslaved people in history: the Haitian Revolution of 1791–1803 “One of the seminal texts about the history of slavery and abolition.... Provocative and empowering.” —The New York Times Book Review The Black Jacobins, by Trinidadian historian C. L. R. James, was the first major analysis of the uprising that began in the wake of the storming of the Bastille in France and became the model for liberation movements from Africa to Cuba. It is the story of the French colony of San Domingo, a place where the brutality of plantation owners toward enslaved people was horrifyingly severe. And it is the story of a charismatic and barely literate enslaved person named Toussaint L’Ouverture, who successfully led the Black people of San Domingo against successive invasions by overwhelming French, Spanish, and English forces—and in the process helped form the first independent post-colonial nation in the Caribbean. With a new introduction (2023) by Professor David Scott.

Wilson Literary Science Writing Award and the Minnesota Book Award for General Nonfiction A Finalist for the Stanford Dolman Travel Book of the Year Award Winner of the Peace Corps Worldwide Special Book Award A Best Book of the Year: NPR, The Wall Street Journal, Smithsonian, Minneapolis Star-Tribune, The Globe and Mail, The BirdBooker Report, Geographical, Open Letter Review Best Nature Book of the Year: The Times (London) "A terrifically exciting account of [Slaght's] time in the Russian Far East studying Blakiston’s fish owls, huge, shaggy-feathered, yellow-eyed, and elusive birds that hunt fish by wading in icy water . . . Even on the hottest summer days this book will transport you.” —Helen Macdonald, author of H is for Hawk, in Kirkus I saw my first Blakiston’s fish owl in the Russian province of Primorye, a coastal talon of land hooking south into the belly of Northeast Asia . . . No scientist had seen a Blakiston’s fish owl so far south in a hundred years . . . When he was just a fledgling birdwatcher, Jonathan C. Slaght had a chance encounter with one of the most mysterious birds on Earth. Bigger than any owl he knew, it looked like a small bear with decorative feathers. He snapped a quick photo and shared it with experts. Soon he was on a five-year journey, searching for this enormous, enigmatic creature in the lush, remote forests of eastern Russia. That first sighting set his calling as a scientist. Despite a wingspan of six feet and a height of over two feet, the Blakiston’s fish owl is highly elusive. They are easiest to find in winter, when their tracks mark the snowy banks of the rivers where they feed. They are also endangered. And so, as Slaght and his devoted team set out to locate the owls, they aim to craft a conservation plan that helps ensure the species’ survival. This quest sends them on all-night monitoring missions in freezing tents, mad dashes across thawing rivers, and free-climbs up rotting trees to check nests for precious eggs. They use cutting-edge tracking technology and improvise ingenious traps. And all along, they must keep watch against a run-in with a bear or an Amur tiger. At the heart of Slaght’s story are the fish owls themselves: cunning hunters, devoted parents, singers of eerie duets, and survivors in a harsh and shrinking habitat. Through this rare glimpse into the everyday life of a field scientist and conservationist, Owls of the Eastern Ice testifies to the determination and creativity essential to scientific advancement and serves as a powerful reminder of the beauty, strength, and vulnerability of the natural world.
