A sky pirate armed with superior weapons of his own invention... First contact with an alien race dangerous enough to threaten the safety of two planets... The arrival of an unseen dark sun whose attendant marauders aimed at the very end of civilization in this Solar System. These were the three challenges that tested the skill and minds of the brilliant team of scientist-astronauts Arcot, Wade, and Morey. Their initial adventures are a classic of science-fiction which first brought the name of their author, John W. Campbell, into prominence as a master of the inventive imagination.

As Earth's faster-than-light spaceship hung in the void between galaxies, Arcot, Wade, Morey and Fuller could see below them, like a vast shining horizon, the mass of stars that formed their own island universe. Morey worked a moment with his slide rule, then said, "We made good time! Twenty-nine light years in ten seconds! Yet you had it on at only half power...." Arcot pushed the control lever all the way to full power. The ship filled with the strain of flowing energy, and sparks snapped in the air of the control room as they raced at an inconceivable speed through the darkness of intergalactic space...

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....

AMUSEMENTS IN MATHEMATICSby HENRY ERNEST DUDENEYPREFACEIn issuing this volume of my Mathematical Puzzles, of which some have appeared in periodicals and others are given here for the first time, I must acknowledge the encouragement that I have received from many unknown correspondents, at home and abroad, who have expressed a desire to have the problems in a collected form, with some of the solutions given at greater length than is possible in magazines and newspapers. Though I have included a few old puzzles that have interested the world for generations, where I felt that there was something new to be said about them, the problems are in the main original...

The Chemical History of a Candle is a series of 6 lectures on chemistry presented to a juvenile audience in 1848. Taught by Michael Faraday - a chemist and physist, and regarded as the best experimentalist in the history of science - it is probably the most famous of the Christmas Lectures of the Royal Society. Taking the everyday burning of a candle as a starting point, Faraday spans the arc from combustion and its products, via the components of water and air (oxygen, hydrogen, nitrogen, carbon), back to the type of combustion that happens in the human body when we breathe...

The Story of the Pony Express offers an in depth account behind the need for a mail route to connect the eastern U.S. with the rapidly populating west coast following the gold rush of California, the springing up of lumber camps, and all incidental needs arising from the settling of the western frontier. Here we learn of the inception of the Pony Express, its formation, successes, failures, facts, statistics, combined with many anecdotes and names of the people who were an integral part of this incredible entity which lasted but less than two years, yet was instrumental in the successful settlement of two thirds of the land mass comprising the expanding country...

Allan Pinkerton (1819-1884), a Scotsman by birth and a barrel-maker by trade, settled in Chicago in its infancy and founded the Pinkertons, the world's first detective agency. Though events associated with the agency after his death have tarnished the name, Pinkerton himself was one of the original human rights advocates. He was a dear friend to John Brown, an advisor to Abraham Lincoln, and 80 years ahead of his time in hiring female detectives. He was also stubborn, irascible, and an egomaniac...

Robert Sterling Yard (February 1, 1861 – May 17, 1945) was an American writer, journalist, and wilderness activist. Born in Haverstraw, New York, Yard graduated from Princeton University and spent the first twenty years of his career in the editing and publishing business. In 1915, he was recruited by his friend Stephen Mather to help publicize the need for an independent national park agency. Their numerous publications were part of a movement that resulted in legislative support for a National Park Service (NPS) in 1916...

“Mr. Benson sees the world, four or five generations hence, free at last from all minor quarrels, and ranged against itself in two camps, Humanitarianism for those who believe in no divinity but that of man, Catholicism for those who believe in no divinity but that of God.” This apocalyptic novel from the early 1900's is sometimes deemed one of the first modern dystopias.

Thoroughly appalled and sickened by the rising numbers of white-on-black murders in the South since the beginning of Reconstruction, and by the unwillingness of local, state and federal governments to prosecute those who were responsible, Ida Bell Wells-Barnett wrote Southern Horrors, a pamphlet in which she exposed the horrible reality of lynchings to the rest of the nation and to the world. Wells explained, through case study, how the federal government's failure to intervene allowed Southern states...

This is a textbook on the science of blood and bloodwork by (1908) Nobel Prize winner, Dr. Paul Ehrlich. Should appeal to hematologists, phlebotomists, and just plain folks interested in how our bodies work.

Just sixty miles from ground zero in Nevada there lies Circle T Ranch run by Hetty Thompson the owner, Barney Hatfield the farmhand, and Johnny Culpepper the assistant manager. It was just another ordinary ranch until, that is, the two cows and the roster hit the nuclear jackpot.(Introduction by Jeanie1914)
