If it is possible to conquer space, then perhaps it is also possible to conquer time. At least that was the theory American scientists were exploring in an effort to explain the new sources of knowledge the Russians possessed. Perhaps Russian scientists had discovered how to transport themselves back in time in order to learn long-forgotten secrets of the past. That was why young Ross Murdock, above average in intelligence but a belligerently independent nonconformist, found himself on a "hush-hush" government project at a secret base in the Arctic. The very qualities that made him a menace in civilized society were valuable traits in a man who must successfully act the part of a merchant...

A lone space traveler arrives on Earth seeking a new planet to colonize, his own world dead. At the same time a mysterious plague has infected Earth that will wipe out all life. Can a lone scientist stop the plague and save the world? Or will the alien find himself on another doomed planet?

Alan Green is a space traveler stranded on a barbaric planet who has been taken slave and made a consort to an insipid and smelly queen. His slave-wife, though beautiful and smart, nags him constantly. He’s given up hope of ever returning to Earth when he hears of two astronauts who have been captured in a kingdom on the other side of the planet, and sets out on an action-packed journey on a ship sailing across vast grasslands on rolling pin-like wheels in a desperate scheme to save them and return home. Due to the non-renewal of its copyright, this book is in the public domain.

Predictability has come a long way. The computers of the future can tell you if you’re going to win a war before you fire a shot. Unfortunately they’re predicting perpetual standoff between the Terran and Centaurian Empires. What they need is something unpredictable, what they get is Thomas Cole, a man from the past accidently dragged forward in time. Will he fit their calculations, or is he the random variable that can break the stalemate? – The Variable Man first appeared in the September, 1953 issue of Space Science Fiction magazine.

The war with the Yucks from Proxima Centauri was claimed to be a stalemate but they were really winning. The mine belts they laid seemed to propagate themselves and were slowly strangling Terran planets. How did they do that? What was their secret? The answer was baffling and the best human minds could only conclude that their ships and mines were somehow alive. So, the next desperate step was to ask "If they are using organic ships, why can't we do the same?". Thus Mr. Spaceship was conceived and carried out. But will a conscious warship do what the generals wish? Perhaps and perhaps something entirely surprising!

The book, also known as Darwin’s Journal of Researches, is a vivid and exciting travel memoir as well as a detailed scientific field journal covering biology, geology, and anthropology that demonstrates Darwin’s keen powers of observation, written at a time when Western Europeans were still discovering and exploring much of the rest of the world. Although Darwin revisited some areas during the expedition, for clarity the chapters of the book are ordered by reference to places and locations rather than chronologically. With hindsight, ideas which Darwin would later develop into his theory of evolution by natural selection are hinted at in his notes and in the book .

John Endlich needed to clean up his act. Gambling, drinking, a hot temper and wanderlust were the last things Rose and the kids needed. So he went to the Homesteaders Office and signed up to terraform Vesta, a chunk of a once thriving alien planet that had exploded from within; a flat lump of crust which was now the remains of a farm on one side and a mining operation on the other. The miners hated Endlich and sabotaged his plans at every opportunity. They were going to kill him and his family if he didn’t find a way to stop them. - Asteroid of Fear was first published in the March, 1951 edition of Planet Stories magazine.

The famous scientific trio of Arcot, Wade and Morey, challenged by the most ruthless aliens in all the universes, blasted off on an intergalactic search for defenses against the invaders of Earth and all her allies. World after world was visited, secret after secret unleashed, and turned to mighty weapons of intense force--and still the Thessian enemy seemed to grow in power and ferocity. Mighty battles between huge space armadas were but skirmishes in the galactic war, as the invincible aliens savagely advanced and the Earth team hurled bolt after bolt of pure ravening energy--until it appeared that the universe itself might end in one final flare of furious torrential power....

"The Machine Stops" is a science fiction short story by E. M. Forster. After initial publication in The Oxford and Cambridge Review (November 1909), the story was republished in Forster's The Eternal Moment and Other Stories in 1928. After being voted one of the best novellas up to 1965, it was included that same year in the populist anthology Modern Short Stories. The story describes a world in which most of the human population has lost the ability to live on the surface of the Earth. Each individual now lives in isolation below ground in a standard 'cell', with all bodily and spiritual needs met by the omnipotent, global Machine.
