The Science of Science Fiction WritingSeven famous science fiction authors--Heinlein, Campbell, "Doc" Smith, Williamson, de Camp, van Vogt, & Taine--present essays on the science and art of writing science fiction. They offer valuable tips and insights to the writer breaking into science fiction, and give the general reader fascinating behind-the-scenes information on how stories are constructed. Originally issued in a limited edition, Of Worlds Beyond rapidly sold out and soon became a collector's item. In response to many requests, Advent arranged to return the book to print, for the benefit of present-day students of science fiction. Many instructors of science fiction courses have chosen Of Worlds Beyond as required reading, and it remains on of the few (and best) explanations of how science fiction stories are written. It is full of useful insights for writers, editors, and readers.ContentsIntroduction by Lloyd Arthur Eshbach"On the Writing of Speculative Fiction" by Robert A.

A little over a century ago, a young Albert Einstein presented his general theory of relativity to the world and utterly transformed our understanding of the universe. He overturned centuries of thinking about gravity by revealing how it arises from the curvature of space and time. Yet general relativity has had far greater consequences. It has revealed that our universe has been expanding from a hot dense state called the big bang. It has changed our understanding of space and time. And it predicts that the universe is an extreme place, containing black holes and possibly wormholes. Using Einstein's insights, today's cosmologists have come to realise that most of the universe is missing in the form of mysterious dark matter and dark energy. In Where the Universe Came From leading cosmologists and New Scientist explain that while we have made great progress, we still have plenty of unfinished business with the cosmos. How does the dark universe shape our cosmic destiny? What is really happening near black holes? Are we any closer to discovering the ripples in space-time predicted by Einstein? Why is relativity not the final answer?

In the midst of the Vietnam War, a young girl struggles to embrace change in this tender family story for fans of Cynthia Lord and Wendy Maas Lucy is a practical, orderly person--just like her dad. He taught her to appreciate reason and good sense, instilling in her the same values he learned at medical school. But when he's sent to Vietnam to serve as an Army doctor, Lucy and her mother are forced to move to San Jose, California, to be near their relatives--the Rossis--people known for their superstitions and all around quirky ways. Lucy can't wait for life to go back to normal, so she's over the moon when she learns her father is coming home early. It doesn't even matter that he's coming back "different." That she can't ask too many questions or use the word "amputation." It just matters that he'll be home. But Lucy quickly realizes there's something very wrong when her mother sends her to spend the summer with the Rossis to give her father some space. Lucy's beside herself, but what's a twelve-year-old to do? It's a curious boy named Milo, a mysterious packet of photographs and an eye-opening mission that makes Lucy see there's more to life than schedules and plans, and helps to heal her broken family. The latest from critically-acclaimed author Tracy Holczer is a pitch-perfect middle grade tale of family and friendship that's sure to delight fans of One for the Murphys and Rules.
