Vannemar Morgan's dream is to link Earth to the stars with the greatest engineering feat of all time: a 24,000-mile-high space elevator. But first he must solve a million technical, political, and economic problems while allaying the wrath of God. For the only possible site on the planet for Morgans Orbital Tower is the monastery atop the Sacred Mountain of Sri Kanda.

Welcome to Ringworld, an intermediate step between Dyson Spheres and planets. The gravitational force created by a rotation on its axis of 770 miles per second means no need for a roof. Walls 1,000 miles high at each rim will let in the sun and prevent much air from escaping. Larry Niven's novel, Ringworld, is the winner of the 1970 Hugo Award for Best Novel, the 1970 Nebula Award for Best Novel, and the 1972 Ditmars, an Australian award for Best International Science Fiction.

The Boy Who Would Live Forever has a sense of wonder and excitement that will satisfy those who loved Gateway and will delight new listeners as well. In Gateway, long after the alien Heechee abandoned their space-station, Gateway (as humans dubbed it) allowed humans to explore new worlds.

The race to colonize Mars was too important, too costly, and America was already too committed, for plans to be scrapped. They would have to make a new Martian. And Roger Torraway was it, candidate for the endless surgery, operation after painful operation, that would enable him to survive on that faraway planet.

The Overlords appeared suddenly over every city - intellectually, technologically, and militarily superior to humankind. Benevolent, they made few demands: unify earth, eliminate poverty, and end war. With little rebellion, humankind agreed, and a golden age began.

A Fire Upon the Deep is the big, breakout book that fulfills the promise of Vinge's career to date: a gripping tale of galactic war told on a cosmic scale.

We were fighting on the wrong side of a war we couldn't win. And that was the good news. The Ruhar hit us on Columbus Day. There we were, innocently drifting along the cosmos on our little blue marble, like the native Americans in 1492. Over the horizon come ships of a technologically advanced, aggressive culture, and BAM! There go the good old days, when humans only got killed by each other. So, Columbus Day. It fits. When the morning sky twinkled again, this time with Kristang starships jumping in to hammer the Ruhar, we thought we were saved.

Ryland Grace is the sole survivor on a desperate, last-chance mission - and if he fails, humanity and the Earth itself will perish. Except that right now, he doesn't know that. He can't even remember his own name, let alone the nature of his assignment or how to complete it. All he knows is that he's been asleep for a very, very long time. And he's just been awakened to find himself millions of miles from home, with nothing but two corpses for company.

Wan-To was the oldest and must powerful intelligence in the universe, a being who played with star systems as a child plays with marbles. Matter occupied so tiny a part of his vast awareness that humans were utterly beneath his notice.

For nearly a billion years, every known sentient species in the universe has been the result of genetic and cultural guidance - or "uplifting" - by a previously uplifted patron race. Then humans are discovered. Having already uplifted chimps and dolphins, humanity clearly qualifies as an intelligent species, but did they actually evolve their own intelligence, or did some mysterious patron race begin the process, then suddenly abandon Earth?

Pell's Station, orbiting the alien world simply called Downbelow, had always managed to remain neutral in the ever escalating conflict between The Company, whose fleets from Earth had colonized space, and its increasingly independent and rebellious colony worlds.

The Last Theorem is a story of one man’s mathematical obsession, and a celebration of the human spirit and the scientific method.

Science fiction can often seem to be pure imaginative fantasy, but many authors are more fluent in real science than many readers and viewers may realize. Professor Charles L. Adler of St. Mary’s College of Maryland was the perfect choice for this subject, as he is both a longtime science-fiction fan and a real-world scientist. Professor Adler’s talent for using literature to shine a light on science - both the accurate and not-so-accurate versions employed by creators, spanning two centuries - makes this course a great survey for fans of both science fact and science fiction.
