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.

“Ghosts!” cried the engineer wildly, flinging his arms about. “I’ve seen them, but will anyone believe me?” Bigman said, “Ghosts! Are you nuts?” At once Mindes screamed, “You don’t believe me either. But I’ll prove it.” With a harsh screech of laughter, he drew his blaster, and with frenzied speed, before Bigman could move to stop him, he aimed it at Lucky at pointblank range and squeezed the trigger … Can Bigman save Lucky, before it’s too late?

As the people of Earth develop atomic power, they are recorded as having achieved maturity by the Galactic keeper of records. But when the keeper learns that they have not yet penetrated space, and that they test their atomic weapons on the planetary surface, he strikes them from the record, commenting that Earth people are 'Silly Asses'.

Isaac Asimov has never laid claim to the title of “Mr. Science Fiction,” but he personifies science fiction in many ways. For one thing, he has grown up with the field, improving as he went; for another, he is actually a teacher of science by profession. But most significant, perhaps, is the scope of his vision, ranging (like that of science fiction itself) from the infinitely vast - as in many of his novels - to the poignantly small - as in this story… Narrated by John W. Michaels.

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.

Isaac Asimov, known primarily for his science fiction stories, was also a scientist. In cooperation with the Senior Scholastic magazine, he composed this wonderful and fascinating work of historical nonfiction. Twenty-six far-reaching discoveries and the twenty-nine scientists who made them—from Archimedes, who boasted he could move the world, to Goddard, who sent the first liquid-fuel rocket toward space.

A research spaceship from Earth lands on Saybrook's Planet to investigate a report by an earlier colony ship. The colony ship's captain, Saybrook, had reported that the planet's abundant plant and animal life was all part of a single organism with a unified consciousness. That organism was able to induce pregnancy in all the colony ship's female animals, and all the offspring born had green patches of fur instead of eyes, a sign that they were part of the planetary organism.

Dans ce second et dernier volume dédié à l'histoire romaine, l'immense Isaac Asimov emmène ses lecteurs à travers les quatre siècles durant lesquels Rome assura son hégémonie sur le monde occidental, apportant la paix à une centaine de millions de personnes, tout en développant deux des plus conséquents héritages de l'Antiquité : le droit et le christianisme. Se plaçant en chroniqueur lucide, Asimov, au moyen d'anecdotes savoureuses et d'apartés, relie la grande histoire, celle des batailles et des empereurs, à la « petite », celle du quotidien et des masses anonymes.

"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."
