Book Description
In 1905 Einstein found from relativity that there is an absolute lightbarrier. He reiterated his ¿finden¿ in 1916, writing, ¿¿We conclude that in thetheory of relativity the velocity c plays the part of limiting velocity, which canneither be reached nor exceeded by any real body.¿ Poincaré and Lorentz didnot share Einstein¿s view of relativity in that regard. Nor, later, did Fermi andTeller it seems. There were others who hesitated to come forward. Then in a1921 lecture and a 1922 look, ¿sidelights on Relativity,¿ Einstein wrote (pp. 35-6), ¿Poincaré is right. The idea of the measuring-rod and the idea of the clockco-ordinated with it in the theory of relativity do not find their exactcorrespondence in the real world.¿Thus the light barrier was questioned by the same man who erected it, andthe last theoretical obstacle to practical star travel was mortally wounded butfew noticed. There is still a conditional light barrier, but no longer one that isimpenetrable. It became clear that the second postulate of special relativity doesnot equate to an absolute light barrier as many continue to believe even to thisday; some highly-regarded scientists continue to subscribe to this faulty logic:¿I believe that special relativity is correct and consequently exceeding thespeed of light [by] (just accelerating more and more) is impossible,¿¿Don Lincoln, Fermilab, email dated 3 Feb. 2005.Such statements reflect a misunderstanding of the second postulate. The key isthat the second postulate applies to photons but not to rocketships; rocketshipsare not macrophotons as Sachs pointed out.In the September 1971 issue of the journal ¿Physics Today¿ MendelSachs wrote about Einstein¿s 1921-22 ¿change of mind¿ as he referred to it,again in 1985, 1993 and at other times; but Sachs¿ writings were scorned byother scientists. It was as if others wanted there to be a truly impenetrable lightbarrier perhaps because it seemed to hold open the exciting promise of timetravel. The first author became aware of Sachs¿ writings in 2004 and the twoexchanged views for a time as reported here.This book presents a hard-science case for practical star travel. The firstsix chapters lay it all out in a logical and factual manner consistent with thetheory of relativity. Chapters 7 & 8 outline a ¿Grand Experiment¿ designed toprobe the light barrier. Chapters 7-9 give future-fiction accounts of possiblescenarios of Humanity¿s first hesitant steps to the stars. Chapter 10 presents aseparate argument questioning the idea of an absolute light barrier.

Book Description
The uplifting, adventure-filled memoir of one groundbreaking scientist’s quest to develop new ways to fight illness and disease through the healing powers of plants. “A fascinating and deeply personal journey.” —Amy Stewart, author of Wicked Plants and The Drunken Botanist Traveling by canoe, ATV, mule, airboat, and on foot, Dr. Cassandra Quave has conducted field research everywhere from the flooded forests of the remote Amazon to the isolated mountaintops in Albania and Kosovo—all in search of natural compounds, long-known to traditional healers, that could help save us all from the looming crisis of untreatable superbugs. Dr. Quave is a leading medical ethnobotanist—someone who identifies and studies plants that may be able to treat antimicrobial resistance and other threatening illnesses—helping to provide clues for the next generation of advanced medicines. And as a person born with multiple congenital defects of her skeletal system, she's done it all with just one leg. In The Plant Hunter, Dr. Quave weaves together science, botany, and memoir to tell us the extraordinary story of her own journey.

Book Description
Some prophecies thwart danger. Others create it. “Fans of contemplative, psychologically rich (but no less action-packed) fantasies à la Ursula Le Guin will welcome this warm, inventive debut” (BCCB, starred review). High in their mountain covens, red witches pray to the Goddess, protecting the Witchlands by throwing the bones and foretelling the future. But it’s all fake. At least, that’s what Ryder thinks. He doubts the witches really deserve their tithes—one quarter of all the crops his village can produce. And even if they can predict the future, what danger is there to foretell, now that his people’s old enemy, the Baen, has been defeated? But when a terrifying new magic threatens both his village and the coven, Ryder must confront the beautiful and silent witch who holds all the secrets. Everything he’s ever believed about witches, the Baen, magic, and about himself will change when he discovers that the prophecies he’s always scorned…are about him. Laced with rich, imagined histories; miles of catacombs; and prophecies true and false, Witchlanders takes place in an evocative, tantalizingly vibrant world and raises equally evocative questions: Who gets to defines history? When does a legend become a crutch? And why does the enemy in war look a lot like the hero? Lena Coakley’s first novel is a lush, chilling story that is sure to send shivers through your finger bones.

Book Description
First published in 1933, "The Shape of Things to Come" is science fiction novel written by H. G. Wells. Within it, world events between 1933 and 2106 are speculated with a single superstate representing the solution to all humanity's problems. A classic example of Wellsian prophesy, this volume is highly recommended for fans of his work and of the science fiction genre. Herbert George Wells (1866 - 1946) was a prolific English writer who wrote in a variety of genres, including the novel, politics, history, and social commentary. Today, he is perhaps best remembered for his contributions to the science fiction genre thanks to such novels as "The Time Machine" (1895), "The Invisible Man" (1897), and "The War of the Worlds" (1898). Many vintage books such as this are becoming increasingly scarce and expensive. We are republishing this book now in an affordable, modern, high-quality edition complete with a specially commissioned new biography of the author.

Book Description
The technology of the next few decades could possibly allow us to explore with robotic probes the closest stars outside our Solar System, and maybe even observe some of the recently discovered planets circling these stars. This book looks at the reasons for exploring our stellar neighbors and at the technologies we are developing to build space probes that can traverse the enormous distances between the stars. In order to reach the nearest stars, we must first develop a propulsion technology that would take our robotic probes there in a reasonable time. Such propulsion technology has radically different requirements from conventional chemical rockets, because of the enormous distances that must be crossed. Surprisingly, many propulsion schemes for interstellar travel have been suggested and await only practical engineering solutions and the political will to make them a reality. This is a result of the tremendous advances in astrophysics that have been made in recent decades and the perseverance and imagination of tenacious theoretical physicists. This book explores these different propulsion schemes – all based on current physics – and the challenges they present to physicists, engineers, and space exploration entrepreneurs. This book will be helpful to anyone who really wants to understand the principles behind and likely future course of interstellar travel and who wants to recognizes the distinctions between pure fantasy (such as Star Trek’s ‘warp drive’) and methods that are grounded in real physics and offer practical technological solutions for exploring the stars in the decades to come.

Book Description
The books in the Florida and the Caribbean Open Books Series demonstrate the University Press of Florida’s long history of publishing Latin American and Caribbean studies titles that connect in and through Florida, highlighting the connections between the Sunshine State and its neighboring islands. Books in this series show how early explorers found and settled Florida and the Caribbean. They tell the tales of early pioneers, both foreign and domestic. They examine topics critical to the area such as travel, migration, economic opportunity, and tourism. They look at the growth of Florida and the Caribbean and the attendant pressures on the environment, culture, urban development, and the movement of peoples, both forced and voluntary. The Florida and the Caribbean Open Books Series gathers the rich data available in these architectural, archaeological, cultural, and historical works, as well as the travelogues and naturalists’ sketches of the area in prior to the twentieth century, making it accessible for scholars and the general public alike. The Florida and the Caribbean Open Books Series is made possible through a grant from the National Endowment for the Humanities and the Andrew W. Mellon Foundation, under the Humanities Open Books program.
