  Travels in Four Dimensions: The Enigmas of Space and Time

  Space and time are the most fundamental features of our experience of the world, and yet they are also the most perplexing. Does time really flow, or is that simply an illusion? Did time have a beginning? What does it mean to say that time has a direction? Does space have boundaries, or is it infinite? Is change really possible? Could space and time exist in the absence of any objects or events? What, in the end, are space and time? Do they really exist, or are they simply the constructions of our minds? Robin Le Poidevin provides a clear, witty, and stimulating introduction to these deep questions and many other mind-boggling puzzles and paradoxes. He gives a vivid sense of the difficulties raised by our ordinary ideas about space and time, but he also gives us the basis to think about these problems independently, avoiding large amounts of jargon and technicality. His book is an invitation to think philosophically rather than a sustained argument for particular conclusions, but Le Poidevin does advance and defend a number of controversial views. He argues, for example, that time does not actually flow, that it is possible for space and time to be both finite and yet be without boundaries, and that causation is the key to an understanding of one of the deepest mysteries of time: its direction. Drawing on a variety of vivid examples from science, history, and literature, Travels in Four Dimensions brings to life some of the most profound questions imaginable.

  Robots in Space: Technology, Evolution, and Interplanetary Travel (New Series in NASA History)

  Given the near incomprehensible enormity of the universe, it appears almost inevitable that humankind will one day find a planet that appears to be much like the Earth. This discovery will no doubt reignite the lure of interplanetary travel. Will we be up to the task? And, given our limited resources, biological constraints, and the general hostility of space, what shape should we expect such expeditions to take?In Robots in Space, Roger Launius and Howard McCurdy tackle these seemingly fanciful questions with rigorous scholarship and disciplined imagination, jumping comfortably among the worlds of rocketry, engineering, public policy, and science fantasy to expound upon the possibilities and improbabilities involved in trekking across the Milky Way and beyond. They survey the literature—fictional as well as academic studies; outline the progress of space programs in the United States and other nations; and assess the current state of affairs to offer a conclusion startling only to those who haven’t spent time with Asimov, Heinlein, and Clarke: to traverse the cosmos, humans must embrace and entwine themselves with advanced robotic technologies.Their discussion is as entertaining as it is edifying and their assertions are as sound as they are fantastical. Rather than asking us to suspend disbelief, Robots in Space demands that we accept facts as they evolve.

  Leaving Earth: Space Stations, Rival Superpowers, and the Quest for Interplanetary Travel

  Charged with the ever-present potential for danger and occasionally punctuated by terrible moments of disaster, the history of space exploration has been keenly dramatic. The recent disaster of the Space Shuttle Columbia was a sad but certain reminder that space travel is an extraordinarily dangerous occupation. Oddly enough, it often takes a tragic accident to remind us that we still have a presence in space. In the decades between triumph and tragedy we tend to ignore the fact that there have been scores of space pioneers who have risked their lives to explore our solar system. Indeed, the International Space Station is sometimes referred to as "Alpha," a moniker that implies that it is our first real permanent presence in space. But this notion is frowned upon by the Russians - and for good reason. Prior to the construction of the controversial International Space Station, a host of daring Russian cosmonauts, and a smaller number of intrepid American astronauts, were living in space for months, some of them for over a year. In this definitive account of man's quest to become citizens of the cosmos, noted space historian Robert Zimmerman reveals the great global gamesmanship between Russian and American political leaders that drove us to the stars. Beaten to the Moon by their Cold War enemies, the Russians were intent on being first to the planets. They believed that manned space stations held the greatest promise for reaching other worlds and worked feverishly to build a viable space station program - one that would dwarf American efforts and allow the Russians to claim the vast territories of space as their own.Although unthinkable at the time, the ponderously bureaucratic Soviet Union actually managed to overtake the United States in the space station race. Leveraging their propaganda machine and tyrannical politics to launch a series of daring, dangerous, and scientifically brilliant space exploits, their efforts not only put them far ahead of NASA, they also helped to reshape their own society, transforming it from dictatorship to democracy. At the same time, the American space program at NASA was also evolving, but not necessarily for the better. In fact, the two programs were slowly but inexorably trading places. Drawing on his vast store of knowledge about space travel, as well as hundreds of interviews with cosmonauts, astronauts, and scientists, Zimmerman has superbly captured the excitement and suspense of our recent space-traveling past. For space and history enthusiasts alike, "Leaving Earth" describes a rich heritage of adventure, exploration, research, and discovery.
