Split Infinity

On the technological, decadent world of Proton, someone was trying to destroy Stile, serf and master Gamesman. His only escape lay through a mysterious “curtain” revealed by a loving robot. Beyond the curtain lay Phaze—a world totally ruled by magic. There, his first encounter was with an amulet that turned into a demon determined to choke him to death. And there, he soon learned, his alternate self had already been murdered by sorcery, and he was due to be the next victim. “Know thyself!” the infallible Oracle told him. But first he must save himself as he shuttled between worlds. On Proton, his fate depended on winning the great Games. On Phaze, he could survive only by mastering magic. And if he used any magic at all, the werewolf and the unicorn who were his only friends were determined to kill him at once!

In this brilliant continuation of the epic adventure that began in Split Infinity, Piers Anthony again proves himself a master of both fantasy and science fiction For Stile, life was a matter of shuttling madly between two worlds, with the problems growing greater on each. On the science world of Proton, he was a serf, trying to prove his right to exist by competing in the Great Games. On Phaze, where only magic worked, he was the Blue Adept, trying to master the powers of sorcery. And on both worlds, someone was trying to assassinate him. Aside from winning increasingly difficult contests with no time to prepare, all he had to do was win the love of the Lady Blue, fight a dragon, discover the ultimate weapon—and, of course, seek the paranoid Adept or the all-powerful Citizen who was trying to kill him! And now, just when things were growing impossible, he had to fight a mortal duel with the unicorn Herd Leader, against whom his magic powers were useless!

A once peaceful planet of refugees faces complete annihilation in this hard science fiction sequel to Brightness Reef. Book Two in the Uplift Storm Trilogy It’s illegal to occupy the planet Jijo, but six castaway races have managed to coexist there for some time. They’ve successfully hidden from watchful law enforcers of the Five Galaxies—until now . . . After making an amazing discovery far away—a derelict armada whose mere existence triggered interstellar war—the Terran exploration vessel Streaker and its crew of humans and dolphins arrive at Jijo in search of sanctuary from the Galactic forces out to destroy them. But they were followed. As behemoth Galactic starships descend upon Jijo, heroic—and terrifying—choices must be made. Together, human and alien settlers must choose whether to fight the invaders or join them. The crew of the Streaker, meanwhile, discovers something that just might save Jijo and its inhabitants . . . or destroy every last one of them. “Well paced, immensely complex, highly literate . . . Superior SF.” —Publishers Weekly, starred review “An imaginative drama of excitement and wonder . . . The sheer virtuosity of the prose alone makes this book worth reading.” —SF Site

THE SEQUEL TO LIFESPAN OF STARLIGHT A split-second decision, a single time-skip. The world that you know, gone in a blink. Now a sharp and adept time-skipper, Scout jumps years ahead to find the world transformed. Technology has accelerated and the people she knows have grown up, or disappeared. Most pressing, the government that she was trying to escape has used the time to prepare for the return of the time skippers. Caught between finding the mother she left behind and time-skipping ahead with Mason, a series of events lead Scout deeper into the tunnel than ever before. The only way out is by the strength of her love and the power of her mind. The illusion of time has one more surprise, one with the power to change everything.

A dynamic exploration of infinity In Infinity and the Mind, Rudy Rucker leads an excursion to that stretch of the universe he calls the “Mindscape,” where he explores infinity in all its forms: potential and actual, mathematical and physical, theological and mundane. Using cartoons, puzzles, and quotations to enliven his text, Rucker acquaints us with staggeringly advanced levels of infinity, delves into the depths beneath daily awareness, and explains Kurt Gödel’s belief in the possibility of robot consciousness. In the realm of infinity, mathematics, science, and logic merge with the fantastic. By closely examining the paradoxes that arise, we gain profound insights into the human mind, its powers, and its limitations. This Princeton Science Library edition includes a new preface by the author.

There are some mathematical problems whose significance goes beyond the ordinary - like Fermat's Last Theorem or Goldbach's Conjecture - they are the enigmas which define mathematics. The Great Mathematical Problems explains why these problems exist, why they matter, what drives mathematicians to incredible lengths to solve them and where they stand in the context of mathematics and science as a whole. It contains solved problems - like the Poincaré Conjecture, cracked by the eccentric genius Grigori Perelman, who refused academic honours and a million-dollar prize for his work, and ones which, like the Riemann Hypothesis, remain baffling after centuries. Stewart is the guide to this mysterious and exciting world, showing how modern mathematicians constantly rise to the challenges set by their predecessors, as the great mathematical problems of the past succumb to the new techniques and ideas of the present.

SHORTLISTED FOR THE 2017 ROYAL SOCIETY SCIENCE BOOK PRIZE Even small children know there are infinitely many whole numbers - start counting and you'll never reach the end. But there are also infinitely many decimal numbers between zero and one. Are these two types of infinity the same? Are they larger or smaller than each other? Can we even talk about 'larger' and 'smaller' when we talk about infinity? In Beyond Infinity, international maths sensation Eugenia Cheng reveals the inner workings of infinity. What happens when a new guest arrives at your infinite hotel - but you already have an infinite number of guests? How does infinity give Zeno's tortoise the edge in a paradoxical foot-race with Achilles? And can we really make an infinite number of cookies from a finite amount of cookie dough? Wielding an armoury of inventive, intuitive metaphor, Cheng draws beginners and enthusiasts alike into the heart of this mysterious, powerful concept to reveal fundamental truths about mathematics, all the way from the infinitely large down to the infinitely small.
