¿Es posible revertir el inevitable final del Universo, o el mundo debe acabar de todas formas? es la pregunta que desde un día del siglo XXI, hasta generaciones y generaciones posteriores en el tiempo, hacen los humanos a los ordenadores.

From Heinlein's thought-provoking "Searchlight" and Clarke's dreamy "Reverie", to Asimov's ingenious "Super-Neutron", Bradbury's chilling "Zero Hour", and Zelazny's poetic masterpiece "A Rose for Ecclesiastes", each story explores deep questions of technology, humanity, and the unknown. Carefully curated to represent both iconic tales and lesser-known gems, this volume offers something for every science fiction reader—whether a newcomer or a lifelong fan.

Conway could remember the day, the exact minute, when the news had reached Science Tower. Patrol ships had shot out into space, tracing the pirates; they attacked the asteroid lairs in a fury that was completely unprecedented. Whether they caught the particular villains who had gutted the Venus-bound ship none could ever say, but the pirate power had been broken from that year on. And the patrol ships found something else: a tiny lifeboat winding a precarious orbit between Venus and Earth, radiating its coldly automatic radio calls for help.

La Fundación yace en ruinas, arrasada por la inteligencia mutante del Mulo. Sin embargo, se rumorea que Hari Seldon, el científico que lo inició todo, ha establecido una Segunda Fundación al otro lado de la galaxia, cuya ubicación exacta es un secreto guardado desde hace tiempo. Obligada a revelar su existencia, la Segunda Fundación deberá enfrentarse a la voluntad destructora del Mulo, con el añadido de que los supervivientes de la Primera Fundación también quieren acabar con ella…

Mientras la sociedad terrestre rechaza a los robots humanoides, los Mundos Exteriores, antiguas colonias de la Tierra, han basado su economía en el trabajo de los robots, desarrollando así una sociedad altamente tecnológica, mucho más que la terrestre, en la que los individuos no soportan la presencia de sus congéneres: todos los contactos sociales se producen por medio de proyecciones holográficas. Por eso, el detective Baley no sabe por dónde empezar cuando le envían a Solaria a resolver el primer asesinato que se produce en doscientos años.

Step into the sharp, idea-driven imagination of Isaac Asimov with this carefully selected collection of classic short fiction.

In a time before the Foundations, psychohistory’s creator Hari Seldon is made to stand before the Emperor of the crumbling Galactic Empire to present how his scientific theory of predicting the future might be applied to the real world. However, Hari refuses to deploy his theory for political gain, setting off instead with reporter Chetter Hummin in quest of a place to safely apply his theory: Earth, the original home of humanity. All records of Earth have been lost to time. Hari will therefore have to look back into the past, in order to seal the future of humanity for ever.

Watch out - the Earth just fell into a dark sun's orbit! Or maybe you'd rather visit a theme park called Hell? These are just two of the strange and unnerving tales you'll find in this collection of great science fiction and fantasy stories.

Lucky Starr’s Ergometrics probed space with widely stretching fingers. It detected many ships, but Lucky watched only for the one which he would recognize with certainty the instant it appeared. Nor did he fail. At a distance of twenty-million miles, the first quiverings roused his suspicions. At 100-thousand miles, his telescope showed it as a faint dot. At ten thousand, it had form and shape—it was the flagship of Anton, the pirate chieftain! At a thousand miles, Lucky sent out his first message—a demand that Anton return to Earth.

Desde hace doce mil años, la humanidad prospera en una galaxia gobernada por el Imperio desde la majestuosa ciudad de Trántor. Todos creen que la estabilidad durará para siempre hasta que Hari Seldon predice, mediante su revolucionaria teoría de la psicohistoria, un futuro de ruina y destrucción. Desterrado al planeta Terminus, Seldon establecerá una colonia con las mentes más brillantes del Imperio, una Fundación que esconde la clave para cambiar el destino de la galaxia.

The First Foundation has been defeated, crushed by the formidable mental powers of the Mule. But whispers of the mysterious Second Foundation, the only hope of defeating the Mule, are beginning to spread. Surviving members of the First Foundation also fear the secret powers of the Second Foundation, vowing to find and destroy it. However, the location of the Second Foundation remains shrouded in mystery. Finding it will lead the Foundation to the opposite end of the Galaxy, where the fate of Seldon’s two Foundations awaits.

Sabotage!!! Agrav. It was the century’s most important advance in space travel … and an experiment so revolutionary that only the men who huddled beneath the surface of Jupiter Nine were permitted to know its full meaning. Yet someone else did know—knew everything, saw everything, head everything—and was diabolically sabotaging the top-secret mission. Who or what the enemy was, Lucky Starr didn’t know. But one thing was certain: the deadly force was not human … not even remotely human!

Un clásico entre los clásicos de la ciencia ficción. Esta historia, que apareció por primera vez en 1976, fue mi exposición más clarividente del desarrollo de los robots. Trataba del deseo de un robot de convertirse en hombre y la forma en que realizaba este deseo, paso a paso. No tenía intención de escribir esta historia cuando la empecé, se escribió sola, y se trazó y entrelazó en la máquina de escribir. Acabó siendo la tercera de mis historias favoritas, entre todas las escritas.

First published fifteen years ago, shortly after his death, inside this collection are some of the finest short stories of science fiction writing from one of the genre’s greatest writers, Isaac Asimov. Isaac Asimov was the Grand Master of the Science Fiction Writers of America, the founder of...

From a distance it seemed an emerald green, fairyland bubble! Aphrodite, the largest city on Venus, deep beneath the planet’s sea. Earthmen had established an incredible civilization, but now it is threatened by an unknown force preying on men’s minds. “Bigman’s head snapped back at a sudden new and strange sound. It was a voice, flat, without intonation. It said, “Do not tamper with your machine of far-reaching sound. We do not wish it.” Bigman turned. His mouth fell open and, for a moment, stayed so. He said, “Who said that? Where is it?” Lucky said, “Easy, Bigman. It was inside your head.”

Earth officials were hard on the heels of the mysterious Sirian spy, Agent X, when he blasted off in a stolen spaceship. But before they could catch him, the master spy jettisoned the capsule that held his report into the icy rings of Saturn. In a flash, Lucky Starr and Bigman Jones found themselves in a race with the Sirian war fleet to recover the top secret information ...

In this 1972 treatise, Isaac Asimov takes the listener on an historic journey through the development of man's understanding of electricity, chemistry, and - ultimately - nuclear energy. Asimov's incomparable ability to simplify the complex is apparent as he guides you through the milestones of scientific thought that connected ideas about electricity and magnetism to the nature of matter, and led to the advances in discovery through the first half of the 20th century that resulted in the harnessing of previously unknown energy directly from the heart of the atom.

Aucune nation dans l'histoire n'a laissé au monde un héritage aussi grand que celui des Grecs. Il semble à peine croyable qu'un peuple aussi dispersé, installé sur les îles et péninsules rocheuses de la mer Égée, ait pu accomplir tant de choses ; mais il a excellé dans tout ce qu'il a entrepris, qu'il s'agisse de guerre ou de politique, d'art ou d'athlétisme, de littérature ou de philosophie. Les Grecs ont donné une nouvelle définition de l'humanité. Leurs idéaux, leurs héros sont devenus les nôtres.

What would a child of the future envision a classroom of the 20th century to look like? This is a question that is explored in a rare piece of science fiction from master writer Isaac Asimov.

While written decades ago it's uncanny to hear the similarities to our present.
