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.

This collection features three classic, dramatized Isaac Asimov stories: "Pebble in the Sky", "Nightfall", and "Hostess".

In 1966, Isaac Asimov and Theodosius Dobzhansky wrote The Genetic Effects of Radiation as a public information resource for the US Atomic Energy Commission. In Asimov's typically incisive and easy-to-understand style, the pair presents an overview of genetics, and how inherited traits can be influenced by external factors, including radiation, both environmental and man-made.

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.

And we dream of a time when we have developed a theory of everything—a theory that answers all questions. Einstein's Unfinished Dream explores the cutting-edge research of modern particle physicists that pushes us slowly towards a theory of everything....

Comet begins with a breathtaking journey through space astride a comet. Pulitzer Prize-winning astronomer Carl Sagan, author of Cosmos and Contact, and writer Ann Druyan explore the origin, nature, and future of comets, and the exotic myths and portents attached to them. The authors show how comets have spurred some of the great discoveries in the history of science and raise intriguing questions about these brilliant visitors from the interstellar dark.

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.

This classic science fiction masterwork by Isaac Asimov weaves stories about robots, humanity, and the deep questions of existence into a novel of shocking intelligence and heart.

Beginning with the death of Stalin in 1953, the "sixties" era in the Soviet Union was just as vibrant and transformative as in the West. The ideological romanticism of the revolutionary years was revived, with renewed emphasis on egalitarianism, equality, and the building of a communist utopia. Mass terror was reined in, great victories were won in the space race, Stalinist cultural dogmas were challenged, and young people danced to jazz and rock and roll. Robert Hornsby examines this remarkable and surprising period.
