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.

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.

Caught up in an experiment gone wrong, Joseph Schwartz is transported forward in time from post-war Chicago to the heyday of the first Galactic Empire. Earth, he soon learns, is a backwater, despised by the other two hundred million planets of the Empire because its people dare to claim it as the original home of man. And Earth is poor, with great areas of radioactivity ruining much of its soil – so poor that everyone is sentenced to death at the age of sixty. And Joseph Schwartz is sixty-two.
