Winner of the Pulitzer Prize A metaphorical fugue on minds and machines in the spirit of Lewis Carroll Douglas Hofstadter's book is concerned directly with the nature of "maps" or links between formal systems. However, according to Hofstadter, the formal system that underlies all mental activity transcends the system that supports it. If life can grow out of the formal chemical substrate of the cell, if consciousness can emerge out of a formal system of firing neurons, then so too will computers attain human intelligence. Gödel, Escher, Bach is a wonderful exploration of fascinating ideas at the heart of cognitive science: meaning, reduction, recursion, and much more.

In 2029, the United States is engaged in a bloodless world war that will wipe out the savings of millions of American families. Overnight, on the international currency exchange, the ''almighty dollar'' plummets in value, to be replaced by a new global currency, the ''bancor.'' In retaliation, the president declares that America will default on its loans. ''Deadbeat Nation'' being unable to borrow, the government prints money to cover its bills. The Mandibles have been counting on a sizable fortune filtering down when their ninety-seven-year-old patriarch dies. Once the inheritance turns to ash, each family member must contend with disappointment, but also-- as the US economy spirals into dysfunction-- the challenge of sheer survival.

"A provocative and very funny page-turner..."--Wall Street Journal With dry wit and psychological acuity, this near-future novel explores the aftershocks of an economically devastating U.S. sovereign debt default on four generations of a once-prosperous American family. Down-to-earth and perfectly realistic in scale, this is not an over-the-top Blade Runner tale. It is not science fiction. In 2029, the United States is engaged in a bloodless world war that will wipe out the savings of millions of American families. Overnight, on the international currency exchange, the “almighty dollar” plummets in value, to be replaced by a new global currency, the “bancor.” In retaliation, the president declares that America will default on its loans. “Deadbeat Nation” being unable to borrow, the government prints money to cover its bills. What little remains to savers is rapidly eaten away by runaway inflation. The Mandibles have been counting on a sizable fortune filtering down when their ninety-seven-year-old patriarch dies. Once the inheritance turns to ash, each family member must contend with disappointment, but also—as the U.S. economy spirals into dysfunction—the challenge of sheer survival. Recently affluent, Avery is petulant that she can’t buy olive oil, while her sister, Florence, absorbs strays into her cramped household. An expat author, their aunt, Nollie, returns from abroad at seventy-three to a country that’s unrecognizable. Her brother, Carter, fumes at caring for their demented stepmother, now that an assisted living facility isn’t affordable. Only Florence’s oddball teenage son, Willing, an economics autodidact, will save this formerly august American family from the streets. The Mandibles is about money. Thus it is necessarily about bitterness, rivalry, and selfishness—but also about surreal generosity, sacrifice, and transformative adaptation to changing circumstances.

“Instead of 1984, read this.” —Washington Post From New York Times bestselling author Lionel Shriver, a near-future novel that explores the aftershocks of an economically devastating U.S. sovereign debt default on four generations of a once-prosperous American family In 2029, the United States is engaged in a bloodless world war that will wipe out the savings of millions of American families.

The lion cannot guard himself from the toils, nor the fox from wolves. A Prince must therefore be a fox to discern toils, and a lion to drive off wolves. The modern-day term “Machiavellian” is used to describe deception, dishonesty, and cruelty to meet a goal. The Prince by Niccolò Machiavelli was written as a guide for autocrats on how to govern using means that were meant to deceive and manipulate a government’s constituency—to the extent of advocating the use of evil for political expediency. In this classic work, the end justifies the means reigns paramount to Machiavelli’s system of government.

Have you, like the rest of the world, speculated as to the identity of Satoshi Nakamoto, anonymous creator of Bitcoin? The world's first cryptocurrency, Bitcoin went online in 2009 and has since revolutionized our concepts of currency and money. Not supported by any government or central bank, completely electronic, Bitcoin is a virtual currency based on advanced cryptographic systems. Like the currency he created, the identity of Bitcoin's creator Satoshi Nakamoto is virtual, existing only online. The Nakamoto persona, which may represent an individual or a group, exists only in the online publications that introduced and explained Bitcoin during its earliest days. Here, collected and professionally published for the first time are the essential writings that detail Bitcoin's creation. Included are - Satoshi Nakamoto Emails and Posts on Computer Forums Presented in Chronological Order - Bitcoin Fundamentals Presented in Layman's Terms - Bitcoin's Potential and Profound Economic Implications - The Seminal Paper Which Started It All The Book of Satoshi provides a convenient way to parse through what Bitcoin's creator wrote over the span of the two years that constituted his "public life" before he disappeared from the Internet . . . at least under the name Satoshi Nakamoto. Beginning on November 1st 2009 with the publication of the seminal paper describing Bitcoin, this public life ends at about the time PC World speculated as to a possible link between Bitcoin and WikiLeaks, the infamous website that publishes leaked classified materials. Was there a connection? You be the judge. Nakamoto's true identity may never be known. Therefore the writings reproduced here are probably all the world will ever hear from him concerning Bitcoin's creation, workings, and theoretical basis. Want to learn more about Bitcoin? Go directly to the source-the writings of the creator himself, Satoshi Nakamoto!

The fate of Russia hangs in the balance as up-timers and down-timers battle for freedom! The United Sovereign States of Russia struggles to set in place the traditions and legal precedents that will let it turn into a constitutional monarchy with freedom and opportunity for all its citizens. At the same time, they’re trying to balance the power of the states and the federal government. And the USSR is fighting a civil war with Muscovite Russia, defending the new state of Kazakh from invasion by the Zunghars, building a tech base and an economy that will allow its money to be accepted in western Europe, establishing a more solid claim to Siberia, and, in general, keeping the wheels of civilization from coming off and dumping Russia back into the Time of Troubles. Or, possibly even worse, reinstalling the sort of repressive oligarchy that they just got rid of.

NEBULA AWARD FINALIST and sequel to national bestseller, Nebula Award finalist, and Compton Crook Award winner Fire with Fire. Science fiction adventure on a grand scale. When reluctant interstellar diplomat and intelligence operative Caine Riordan returns from humanity’s first encounter with alien races, sudden war clouds burst. With Earth’s fleet shattered by a sneak attack and its survivors fighting for their lives, Caine must rely upon both his first contact and weaponry skills to contend with the non-humanoid enemy. And when the technologically-superior attackers sweep aside the solar system’s last defenses, and traitorous corporations invite the invaders to land ‘security forces,’ humanity fights back with its best weapons: cunning, inventiveness, and guts. But as Earth hurtles towards a final trial by fire that is certain to scar its collective memory, Caine discovers that there may also be large and disturbing gaps in that memory. Clues point to a much earlier inter-species apocalypse, buried in humanity’s own prehistory. Which raises a terrifying possibility: what if the aliens' invasion of Earth is not one of conquest, but preemption? And what if their harrowing memories of a long-past cataclysmic war makes them willing to do anything to keep it from reigniting? Even if that means exterminating the human race. About Trial by Fire: "Gannon's whiz-bang second Tales of the Terran Republic interstellar adventure delivers on the promise of the first (Fire with Fire). . . . The charm of Caines harrowing adventure lies in Gannons attention to detail, which keeps the layers of political intrigue and military action from getting too dense. The dozens of key characters, multiple theaters of operations, and various alien cultures all receive the appropriate amount of attention. The satisfying resolution is enhanced by the promise of more excitement to come in this fascinating far-future universe."—Publishers Weekly Starred Review " . . . offers the type of hard science-fiction those familiar with the John Campbell era of Analog Science Fiction will remember.Gannon throws his readers into an action-packed adventure. A sequel to Fire With Fire, it is a nonstop tale filled with military science-fiction action." —Daily News of Galveston County "[A] white-knuckle adventure . . . with real stakes, and sets up the next challenge for the newly named Terran Republic. Gannon is making it easy for me to meet my goal of reading more military SF this year."—Fantasy Literature Review About Compton Crook award winner for best first novel, Fire with Fire: “Chuck Gannon is one of those marvelous finds—someone as comfortable with characters as he is with technology, and equally adept at providing those characters with problems to solve. Imaginative, fun, and not afraid to step on the occasional toe or gore the occasional sacred cow, his stories do not disappoint.”—David Weber "If we meet strong aliens out there, will we suffer the fate of the Aztecs and Incas, or find the agility to survive? Gannon fizzes with ideas about the dangerous politics of first contact.”—David Brin "The plot is intriguing and then some. Well-developed and self-consistent; intelligent readers are going to like it."—Jerry Pournelle "[T]he intersecting plot threads, action and well-conceived science kept those pages turning."—SF Crowsnest About Starfire series hit, Extremis, coauthored by Charles E. Gannon: “Vivid. . . Battle sequences mingle with thought-provoking exegesis . . .”–Publishers Weekly "It’s a grand, fun series of battles and campaigns, worthy of anything Dale Brown or Larry Bond ever wrote." –Analog About Charles E. Gannon: "[A] strong [writer of] . . . military SF. . .[much] action going on in his work, with a lot of physics behind it. There is a real sense of the urgency of war and the sacrifices it demands." –Locus

Who is John Galt?

Why does he fight his hardest battle against the woman he loves? You will know the answer to these questions when you discover the reason behind the baffling events that play havoc with the lives of the amazing men and women in this book. You will discover why a productive genius becomes a worthless playboy...why a great steel industrialist is working for his own destruction...why a composer gives up his career on the night of his triumph...why a beautiful woman who runs a transcontinental railroad falls in love with the man she has sworn to kill. Atlas Shrugged, a modern classic and Rand’s most extensive statement of Objectivism—her groundbreaking philosophy—offers the reader the spectacle of human greatness, depicted with all the poetry and power of one of the twentieth century’s leading artists.
