Meanwhile, someone - or something - outside of both Foundations seems to be orchestrating events to suit its own ominous purpose.

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.

On the beautiful Outer World planet of Solaria, a handful of human colonists lead a hermit-like existence, their every need attended to by their faithful robot servants. To this strange and provocative planet comes Detective Elijah Baley, sent from the streets of New York with his positronic partner, the robot R. Daneel Olivaw, to solve an incredible murder that has rocked Solaria to its foundations. The victim had been so reclusive that he appeared to his associates only through holographic projection. Yet someone had gotten close enough to bludgeon him to death while robots looked on.

Tandis que les crises qui secouent l'Empire redoublent de violence et annoncent son effondrement définitif, la Fondation créée par le psychohistorien Hari Seldon pour sauvegarder la civilisation devient de plus en plus puissante, suscitant naturellement convoitise et visées annexionnistes. En tout premier lieu, celles de Bel Riose, jeune général qui voit dans les secrets détenus par la Fondation le moyen de monter sur le trône. C'est alors qu'apparaît un mystérieux et invincible conquérant, surnommé le Mulet, que le plan de Seldon n'avait pas prévu.

Prévoyant l'effondrement prochain de l'Empire galactique, le psychohistorien Hari Seldon a jadis créé deux Fondations, l'une officielle, l'autre occulte, afin de préserver la civilisation d'une interminable période de chaos. Pourtant, cinq siècles après leur établissement, alors même que la Première Fondation n'a jamais été aussi puissante, un nouveau protagoniste semble entrer en jeu, œuvrant dans l'ombre à l'insu de tous. Peut-être tient-il entre ses mains le devenir de l'humanité tout entière...

Detective Elijah Baiey is called to the Spacer world Aurora to solve a bizarre case of roboticide. The prime suspect is a gifted roboticist who had the means, the motive, and the opportunity to commit the crime. There's only one catch: Baley and his positronic partner, R. Daneel Olivaw, must prove the man innocent. For in a case of political intrigue and love between woman and robot gone tragically wrong, there's more at stake than simple justice. This time Baley's career, his life, and Earth's right to pioneer the Galaxy lie in the delicate balance.

A robopsychologist must outwit a machine determined to stay hidden in "Little Lost Robot"; a woman’s talent for "Light Verse" overshadows her true accomplishments with her robot servants; "The Last Question" presented to computer after computer over a hundred billion years may remain forever unanswered … and seventeen more future visions from the grand master of science fiction.

Conçue par le psychohistorien Hari Seldon pour restreindre l'ère de chaos résultant de la décadence de l'Empire galactique, la Fondation est désormais aux mains du Mulet, un mutant imprévisible capable de manipuler les esprits et d'imposer sa volonté à quiconque. Avec ses pouvoirs et les immenses ressources que lui procurent la Fondation, il s'est donné pour objectif d'étendre sa domination aux ultimes vestiges de l'Empire défunt.

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.

The fate of the Foundation rests on young Arcadia Darell, only 14 years old and burdened with a terrible secret. As its scientists gird for a final showdown with the Mule, the survivors of the First Foundation begin their desperate search. They too want the Second Foundation destroyed, before it destroys them.

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.

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.
