The Limits To Travel

As affluence grows, it gets easier to travel faster and further. But research shows that, despite this, the average travel time in all societies remains steady at roughly an hour a day. The implication is that people are choosing to increase the distance they regularly travel, rather than opting for shorter journey times. While this clearly offers advantages in terms of reaching more desirable locations, the disadvantages are numerous - not least that of anthropogenic climate change, to which transport is the fastest growing contributor. However, the stability of travel time does not form part of the present conceptual framework of transport policy makers and professionals - consequently, misconceived decisions lead to unintended outcomes. In this intriguing book, David Metz examines the inadequacies inherent in the current thinking, along with the resulting problems, such as pollution, congestion and noise. He highlights the impact of the rapid increase in car use in China and India, and explores the general travel experience, public vs. private transport, and transport technology. In considering to what extent travel could be avoided, he arrives at a new paradigm to underpin sustainable transport policies, based on the fundamental characteristics of human mobility and focusing on quality, not quantity, of travel.

In this compendium of essays, some of the world’s leading thinkers discuss their conceptions of space and time, as viewed through the lens of their own discipline. With an epilogue on the limits of human understanding, this volume hosts contributions from six or more diverse fields. It presumes only rudimentary background knowledge on the part of the reader. Time and again, through the prism of intellect, humans have tried to diffract reality into various distinct, yet seamless, atomic, yet holistic, independent, yet interrelated disciplines and have attempted to study it contextually. Philosophers debate the paradoxes, or engage in meditations, dialogues and reflections on the content and nature of space and time. Physicists, too, have been trying to mold space and time to fit their notions concerning micro- and macro-worlds. Mathematicians focus on the abstract aspects of space, time and measurement. While cognitive scientists ponder over the perceptual and experiential facets of our consciousness of space and time, computer scientists theoretically and practically try to optimize the space-time complexities in storing and retrieving data/information. The list is never-ending. Linguists, logicians, artists, evolutionary biologists, geographers etc., all are trying to weave a web of understanding around the same duo. However, our endeavour into a world of such endless imagination is restrained by intellectual dilemmas such as: Can humans comprehend everything? Are there any limits? Can finite thought fathom infinity? We have sought far and wide among the best minds to furnish articles that provide an overview of the above topics. We hope that, through this journey, a symphony of patterns and tapestry of intuitions will emerge, providing the reader with insights into the questions: What is Space? What is Time?

Are there some things we can never think, or know, let alone do? In this fascinating book, acclaimed author John Barrow reveals the often paradoxical limits on knowledge and achievement, and shows that the notion of `impossibility' has played, and continues to play, a striking role in our thinking, and in the way in which we understand the universe and ourselves. - ;What are the true limits of science and human endeavour? The end of each century leads to a stocktaking of human achievement and our expectation about the future. This new book by John D. Barrow looks at what limits there might be to human discovery and what we might find, ultimately, to be unknowable, undoable, or unthinkable. Weaving together a tapestry of surprises, Barrow explores the frontiers of knowledge, taking in surrealism, impossible figures, time travel, paradoxes of logic and perspective, theological speculations about Beings for whom nothing is impossible -- all stimulate us to contemplate something more that what is. With sufficient time and money at our disposal, why should we find anything impossible? Barrow explores the limits that may be imposed upon a full understanding of the physical Universe by constraints of technology, computes, cost, and complexity. He considers how the nature of the universe's structure prevents us from answering the deepest questions about its beginning, its structure, and its future. And he delves into the deep limits imposed by the nature of knowledge itself, which have profound implications for any quest for complete knowledge. They take us into the debates over the problems of free will and consciousness. G--ouml--;del's famous theorem about our inability to capture the truths of mathematics by rules and axioms is explored to see if it has any implications for science. Clearly and engagingly written, and using simple explanations, this book reveals that impossibility is a deep and powerful notion: that any Universe complex enough to contain conscious beings will contain limits on what those beings can know about their Universe: that what we cannot know defines reality as surely as what we can know. Impossibility is a two-edged sword: it threatens the completeness of the scientific enterprise yet without it there would be no laws of Nature, no science, and no scientists. - ;In this illuminating, well-written account of Limits (with capital L), John D. Barrow chronicles and explains the limits of science as a reality-generation mechanism and why it matters.So for about as good an account as you're going to get of where science stops, read this book. It won't tell you any final answer. But the journey is far more interesting - and important - than the destination. - Nature

The last quarter century has seen a broad, but qualified, belief in the efficacy of market organization slide into an unyielding dogma that the market, as unconstrained as possible, is the best way to govern virtually all economic activity. However, unrestricted markets can often lead to gross inequalities in access to important resources, the creation of monopolies, and other negative effects that require regulation or public subsidies to remedy. In The Limits of Market Organization, editor Richard Nelson and a group of economic experts take a more sophisticated look at the public/private debate, noting where markets are useful, where they can be effective only if augmented by non-market mechanisms, and where they are simply inappropriate. The Limits of Market Organization examines the appropriateness of markets in four areas where support for privatization varies widely: human services, public utilities, science and technology, and activities where market involvement is altogether inappropriate. Richard Murnane makes the case that a social interest in providing equal access to high quality education means that for school voucher plans to be effective, substantial government oversight is necessary. Federal involvement in a transcontinental railroad system was initially applauded, but recent financial troubles at Amtrak have prompted many to call for privatization of the rails. Yet contributor Elliot Sclar argues that public subsidies are the only way to maintain this vital part of the American transportation infrastructure. While market principles can promote competition and foster innovation, applying them in certain areas can actually stifle progress. Nelson argues that aggressive patenting has hindered scientific research by restricting access to tools and processes that could be used to generate new findings. He suggests that some kind of exception to patent law should be made for scientists who seek to build off of patented findings and then put their research results into the public domain. In other spheres, market organization is altogether unsuitable. Legal expert Richard Briffault looks at one such example—the democratic political process—and profiles the successes and failures of campaign finance reform in preventing parties from buying political influence. This important volume shows that market organization has its virtues, but also its drawbacks. Just as regulation can be over-applied, so too can market principles. The Limits of Market Organization encourages readers to think more discriminately about the march toward privatization, and to remember the importance of public institutions.
