Cuando me faltaba poco para cumplir los veinte años y era ya un endurecido lector de ciencia ficción, llevaba leídas muchas historias de robots, y había descubierto que podían calificarse en dos categorías. En la primera categoría estaban los Robots-como-Amenaza. No tengo que explicar demasiado esto. Tales historias eran una mezcla de clanc-clanc y aarghh y Hay algunas cosas que se supone que el hombre no debe conocer. Al cabo de un tiempo empezaron a palidecer a mis ojos, y ya no pude seguir soportándolas

En el mes de mayo del año 987, un joven cayó de su caballo durante una animada partida de caza en lo que es hoy la Francia del noreste. Quedó seriamente lesio¬nado, sangrando de la nariz y la garganta. El 21 de mayo murió. El joven tenía escasa importancia en sí mismo. Su nombre era Luis y era rey, pero esto era todo lo que podía decirse de él. Tenía veinte años de edad, había remado durante un año y su única preocupación verdadera era pasarlo bien. Entró en la historia con el nombre de Luis V, el Holgazán.

Preludio a la Fundación es el primer libro del «Ciclo de la Fundación», tercer bloque de la célebre «Saga de la Fundación», la serie que catapultó al autor en lo más alto de la ciencia ficción. Corre el año 12020 en Trántor, la próspera capital del Imperio Galáctico, una civilización de una complejidad tecnológica y cultural inimaginable. Sin embargo, Hari Seldon, la mente científica más brillante de su época acaba de augurar un desastre colosal a través de la psicohistoria, una nueva ciencia capaz de predecir el futuro mediante fórmulas matemáticas. Cuando el emperador Cleón busque apropiársela, Seldon deberá huir para que sus ideas no caigan en las manos equivocadas. Esta precuela a la famosa trilogía de la Fundación es un hito en la historia de la ciencia ficción y toda una revolución para los lectores, tanto los fans de los libros originales como los que están a punto de embarcarse en este viaje intergaláctico. «Una de las carreras más formidables de la ciencia ficción». --The Times ENGLISH DESCRIPTION The first of two prequel novels in Isaac Asimov's classic science-fiction masterpiece, the Foundation series It is the year 12,020 G.E. and Emperor Cleon I sits uneasily on the Imperial throne of Trantor. Here in the great multidomed capital of the Galactic Empire, forty billion people have created a civilization of unimaginable technological and cultural complexity. Yet Cleon knows there are those who would see him fall--those whom he would destroy if only he could read the future. Hari Seldon has come to Trantor to deliver his paper on psychohistory, his remarkable theory of prediction. Little does the young Outworld mathematician know that he has already sealed his fate and the fate of humanity. For Hari possesses the prophetic power that makes him the most wanted man in the Empire . . . the man who holds the key to the future--an apocalyptic power to be known forever after as the Foundation.

La humanidad, muy probablemente, tuvo su origen en África. Los más antiguos rastros de homínidos (seres que se asemejan al hombre en sus características más que cualquier otra forma de vida) han sido hallados en África. Los más cercanos parientes del hombre en el reino animal, el chimpancé y el gorila, sólo se encuentran aún en África, excepto casos individuales que han sido llevados a otras partes por mediación humana. Durante el par de millones de años de existencia de los homínidos, éstos se expandieron por ámbitos cada vez mayores, pero siempre estuvieron limitados a regiones que podían alcanzar sin atravesar una gran masa de agua. Todos los fósiles de los primeros homínidos que son distintivamente más primitivos que el hombre moderno sólo se han encontrado en África, Europa y Asia, las tres masas terrestres contiguas que constituyen lo que a veces recibe el nombre de la Isla del Mundo. También pueden hallarse vestigios en las islas situadas frente a las costas de esos continentes.

"The Galactic Empire was collapsing. His fall was inexorable, but as slow as the Empire was extensive. It would have gone unnoticed had it not been for a man, Hari Seldon, who knew how to anticipate the future: through the science of psychohistory, he calculated that thirty thousand years of barbarism would happen to the Empire. To shorten the interregnum, Seldon established two Foundations on opposite ends of the Galaxy: The First Foundation, a world of physical scientists whose path through the vicissitudes of history would be marked by the "Seldon crises," a series of twists predicted by the psychohistory; and the Second Foundation, a world of mental scientists that would watch over the course of the First and make the corrections that the passing of the centuries made necessary. Together, both Foundations would constitute the seed of a new Galactic Empire that, thanks to Seldon's plan, would arise just a thousand years after the fall of the previous one."--

"For twelve thousand years the Galactic Empire has ruled supreme. Now it is dying. But only Hari Seldon, creator of the revolutionary science of psychohistory, can see into the future--to a dark age of ignorance, barbarism, and warfare that will last thirty thousand years. To preserve knowledge and save humankind, Seldon gathers the best minds in the Empire--both scientists and scholars--and brings them to a bleak planet at the edge of the galaxy to serve as a beacon of hope for future generations. He calls his sanctuary the Foundation."--

Los límites de la Fundación, sexto libro del «Ciclo de la Fundación', es la continuación de la «Trilogía de la Fundación' o «Ciclo de Trántor', la obra maestra de la ciencia ficción de Isaac Asimov. Golan Trevize, consejero de la Primera Fundación, se pregunta sobre la posibilidad de la supervivencia de la Segunda Fundación. Esta debería haber sido destruida, según la versión oficial, agotándose así los superpoderes mentales de los científicos que la componían y que dirigían en la sombra los aconteceres del Imperio Galáctico. Tras una serie de intrigas políticas, Trevize se verá obligado a exiliarse en una astronave, en compañía del historiador Janov Pelorat. Pero, una vez en el espacio, ambos decidirán dedicarse a la búsqueda del antiguo planeta Tierra... ENGLISH DESCRIPTION The fourth novel in Isaac Asimov's classic science-fiction masterpiece, the Foundation series At last, the costly and bitter war between the two Foundations has come to an end. The scientists of the First Foundation have proved victorious, and now they return to Hari Seldon's long established plan to build a new Empire on the ruins of the old. But rumors persist that the Second Foundation is not destroyed after all--and that its still-defiant survivors are preparing their revenge. Now two exiled citizens of the Foundation--a renegade Councilman and a doddering historian--set out in search of the mythical planet Earth . . . and proof that the Second Foundation still exists. Meanwhile someone--or something--outside of both Foundations seems to be orchestrating events to suit its own ominous purpose. Soon representatives of both the First and Second Foundations will find themselves racing toward a mysterious world called Gaia and a final, shocking destiny at the very end of the universe.

Isaac Asimov's death on April 6, 1992, was a great loss to the world of literary science and freethought. The prolific author's vision is unmatched today, and his pointed honesty shines through in The Roving Mind, now reissued in this special tribute edition.This collection of essays is wide-ranging, reflecting Asimov's extraordinary skill in disseminating knowledge from across the spectrum of human thought. Some of the areas explored in this volume of 62 essays include creationism, pseudoscience, censorship, population, philosophy of science, transportation, computers and corporations of the future, and astronomy. His predictions about cloning which has only recently become the topic of public debate the theory of "technophobia," and other scientific developments are astounding. In a lighter tone, Asimov includes several personal stories from his life including thoughts on his style of writing and memories of family in younger days.With tributes by Arthur C. Clarke, L. Sprague de Camp, Harlan Ellison, Kendrick Frazier, Martin Gardner, Donald Goldsmith, Stephen Jay Gould, E. C. Krupp, Frederik Pohl, and Carl Sagan
