This exploration of the scientific limits of knowledge challenges our deep-seated beliefs about our universe, our rationality, and ourselves. “A must-read for anyone studying information science.” —Publishers Weekly, starred review Many books explain what is known about the universe. This book investigates what cannot be known. Rather than exploring the amazing facts that science, mathematics, and reason have revealed to us, this work studies what science, mathematics, and reason tell us cannot be revealed. In The Outer Limits of Reason, Noson Yanofsky considers what cannot be predicted, described, or known, and what will never be understood. He discusses the limitations of computers, physics, logic, and our own intuitions about the world—including our ideas about space, time, and motion, and the complex relationship between the knower and the known. Yanofsky describes simple tasks that would take computers trillions of centuries to complete and other problems that computers can never solve: • perfectly formed English sentences that make no sense • different levels of infinity • the bizarre world of the quantum • the relevance of relativity theory • the causes of chaos theory • math problems that cannot be solved by normal means • statements that are true but cannot be proven Moving from the concrete to the abstract, from problems of everyday language to straightforward philosophical questions to the formalities of physics and mathematics, Yanofsky demonstrates a myriad of unsolvable problems and paradoxes. Exploring the various limitations of our knowledge, he shows that many of these limitations have a similar pattern and that by investigating these patterns, we can better understand the structure and limitations of reason itself. Yanofsky even attempts to look beyond the borders of reason to see what, if anything, is out there.

Award-winning author Miranda Paul and illustrator Sija Hong present a fresh and fascinating journey to the outer reaches of outer space.

Profiles the land, the nature, and the people of the Outer Banks of North Carolina

Oscar and Lilian Handlin show how the new voyagers in the twentieth century--from Asia, Africa, Australia, and Latin America--record their experiences in the United States. Many accounts are newly translated from Arabic, Persian, Hebrew, and Spanish, and include such authors as Rabindranath Tagore, V. S. Naipaul and Octavio Paz.

As many visitors to Ocracoke will attest, the island's vibrant dialect is one of its most distinctive cultural features. In Hoi Toide on the Outer Banks, Walt Wolfram and Natalie Schilling-Estes present a fascinating account of the Ocracoke brogue. They trace its development, identify the elements of pronunciation, vocabulary, and syntax that make it unique, and even provide a glossary and quiz to enhance the reader's knowledge of 'Ocracokisms.' In the process, they offer an intriguing look at the role language plays in a culture's efforts to define and maintain itself. But Hoi Toide on the Outer Banks is more than a linguistic study. Based on extensive interviews with more than seventy Ocracoke residents of all ages and illustrated with captivating photographs by Ann Ehringhaus and Herman Lankford, the book offers valuable insight on what makes Ocracoke special. In short, by tracing the history of island speech, the authors succeed in opening a window on the history of the islanders themselves.

"Finch is today’s best, most perceptive Cape Cod writer in a line extending all the way back to Henry David Thoreau." —Christian Science Monitor Weaving together Robert Finch’s collected writings from over fifty years and a thousand miles of walking along Cape Cod’s Atlantic coast, The Outer Beach is a poignant, candid chronicle of an iconic American landscape anyone with an appreciation for nature will cherish.

Knowledge about the outer heliosphere and the interstellar medium, which were long treated as two separate fields, has improved dramatically over the past 25 years as a consequence of recent developments: The discovery of interstellar pickup ions and neutral helium inside the heliosphere, the determination of the interstellar hydrogen distribution in the heliosphere obtained using backscattered solar Lyman-alpha radiation, the prediction and subsequent detection of the hydrogen wall just outside of the heliopause, the development of detailed global models for the interaction of solar wind plasma with the interstellar medium, and most recently, direct in-situ plasma and field measurements inside of the heliosheath. At the same time, our understanding of the nearby galactic environment, including the composition and dynamics of the warm gas clouds and hot gas in the local bubble, has benefited greatly from absorption-line spectroscopy using nearby stars as background sources and dynamic modeling. The present volume provides a synopsis of these developments organised into seven sections: Dominant physical processes in the termination shock and heliosheath, three-dimensional shape and structure of the dynamic heliosphere, relation of the plasmas and dust inside and outside of the heliosphere, origin and properties of the very local interstellar medium, energy and pressure equilibria in the local bubble, physical processes in the multiphase interstellar medium inside of the local bubble, and the roles that magnetic fields play in the outer heliosphere and the local bubble. The last theme is probably the most basic of all as magnetic fields play important roles in most of the phenomena discussed here. The volume concludes with four papers providing the "big picture" by looking at the time evolution of both the heliosphere and the local bubble, looking beyond the local bubble, and finally addressing the challenges in modeling the interface between the two media.
