Norby è un robottino davvero unico. E non solo perché ha l'aspetto di un barilotto. I meccanismi che lo compongono provengono da una misteriosa astronave aliena e questo dettaglio gli permette di sottrarsi alle tre leggi della robotica. Può quindi rifiutarsi di obbedire agli ordini; essere un fifone sempre preoccupato di farsi male; e addirittura lottare contro i cattivi. Questo lo rende imprevedibile, buffo e... incredibilmente umano. Insieme al suo amico e proprietario, il cadetto spaziale Jeff Wells, dovrà affrontare l'odioso Ing l'Ingrato, deciso a diventare Imperatore della Terra.

A collection of 20 classic short stories by Isaac Asimov, author of the Foundation series, featuring the definitive and only in-print version of “Nightfall”.

Tout porte à croire que le légendaire berceau de l'humanité, la Terre, se trouve au cœur d'un vaste plan à l'échelle galactique, destiné à garantir en coulisse la pérennité de la civilisation : une synthèse parfaite entre le matérialisme de la Première Fondation et le mentalisme de la Seconde, mise en œuvre par une mystérieuse puissance. Mais comment trouver une planète que beaucoup croient mythique, et dont toute trace a inexplicablement disparu des archives galactiques ?

"L'univers uni, c'est fini. L'Empire galactique se désagrège. Trente mille ans de chaos sont au programme. Et moi, j'en ai trop fait et je suis las. Oui, je m'appelle Hari Seldon et je vois que ce nom vous dit quelque chose. Tout ce que j'ai fait, c'est de poser les équations et d'agir. Les équations ne mentent pas. D'ailleurs vous le savez. Je ne voudrais pas jouer les prophètes, mais quand j'allume mon Premier Radiant, je lis l'avenir de l'humanité. Le chaos prévu sera réduit à un petit millier d'années."

Harry Seldon venait d'inventer la psychohistoire et il n'y voyait qu'une pure spéculation, sans applications pratiques. Mais dès qu'il prit la parole à ce colloque, tout le monde comprit. La psychohistoire ne pouvait pas prédire l'avenir ? Les politiques s'en moquaient ! Ce qui comptait pour eux, c'est que les gens allaient y croire. Ensuite, les équations diraient ce qu'on leur ferait dire. Et si Seldon n'était pas d'accord tant pis pour lui ! Alors, le jeune chercheur s'enfuit en compagnie d'une belle historienne, Dors Venabili.

The way we feel about another person or about objects is often bound up in associations that have no direct connection with the person or object, at all. Often, what we call a "change of heart" comes about sheerly from a change in the many associations which make up our present viewpoint. Now, suppose that these associations could be altered artificially, at the option of the person who was in charge of the process.

The Eternals, the ruling class of the Future, had the power of life and death not only over every human being but over the very centuries into which they were born. Past, Present, and Future could be created or destroyed at will. You had to be special to become an Eternal. Andrew Harlan was special. Until he committed the one unforgivable sin - falling in love. Eternals weren’t supposed to have feelings. But Andrew could not deny the sensations that were struggling within him. He knew he could not keep this secret forever. And so he began to plan his escape.

Arguably the greatest science fiction writer who ever lived, Isaac Asimov also possessed one of the most brilliant and original minds of our time. His accessible style and far-reaching interests in subjects ranging from science to humor to history earned him the nickname "the Great Explainer". I. Asimov is his personal story - vivid, open, and honest - as only Asimov himself could tell it.

"It all began with my month's layoff between galactic service assignments. I reached Marsport for the ususla three-day stopover. Before landing, I received a spacegram from my wife, Hilda, saying she would stay and wait for me on Earth. So I called Flora and set a date. As I stepped out of the Video Booth, the first whiff of catastrophe nudged itself up to me. Rog Crinton said, 'Red Emergency Alert - come with me. Jack Hawk is dead. The galactic drug menace and his killer is on his way here.'"

From the late 1940's through the 1950's, in a world where space travel and nuclear annihilation were no longer merely the stuff of fantasy, science fiction began to achieve a new popularity. And, the work of noted genre writers began to be adapted in movies and radio programs. Based (however implausibly) on science, these radio broadcasts reflected the depths of the nation's fears, and the boundlessness of its imagination.

What happens when a robot begins to question its creators? What would be the consequences of creating a robot with a sense of humour? Or the ability to lie? How do we truly tell the difference between man and machine? In I, Robot, Asimov sets out the Three Laws of Robotics - designed to protect humans from their robotic creations - and pushes them to their limits and beyond.

In the 23rd century, pioneers have escaped the crowded earth for life in self-sustaining orbital colonies. One of the colonies, Rotor, has broken away from the solar system to create its own renegade utopia around an unknown red star two light-years from Earth: a star named Nemesis. Now a 15-year-old Rotorian girl has learned of the dire threat that nemesis poses to Earth’s people - but she is prevented from warning them. Soon, she will realize that Nemesis endangers Rotor as well.

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. 

Première Loi : Un robot ne peut porter atteinte à un être humain ni, restant passif, laisser cet être humain exposé au danger. Deuxième Loi : Un robot doit obéir aux ordres donnés par les êtres humains, sauf si de tels ordres entrent en contradiction avec la Première Loi. Troisième Loi : Un robot doit protéger son existence dans la mesure où cette protection n’entre pas en contradiction avec la Première ou la Deuxième Loi.

Ignition! is the story of the search for a rocket propellant which could be trusted to take man into space. This search was a hazardous enterprise carried out by rival labs who worked against the known laws of nature, with no guarantee of success or safety. John Drury Clark writes with irreverent and eyewitness immediacy about the development of the explosive fuels strong enough to negate the relentless restraints of gravity. The resulting volume is as much a memoir as a work of history, sharing a behind-the-scenes view of an enterprise that eventually took men to the moon.
