Book excerpt: At once far flung and intimate, a fascinating look at how finding our way make us human. "A marvel of storytelling." —Kirkus (Starred Review) In this compelling narrative, O'Connor seeks out neuroscientists, anthropologists and master navigators to understand how navigation ultimately gave us our humanity. Biologists have been trying to solve the mystery of how organisms have the ability to migrate and orient with such precision—especially since our own adventurous ancestors spread across the world without maps or instruments. O'Connor goes to the Arctic, the Australian bush and the South Pacific to talk to masters of their environment who seek to preserve their traditions at a time when anyone can use a GPS to navigate. O’Connor explores the neurological basis of spatial orientation within the hippocampus. Without it, people inhabit a dream state, becoming amnesiacs incapable of finding their way, recalling the past, or imagining the future. Studies have shown that the more we exercise our cognitive mapping skills, the greater the grey matter and health of our hippocampus. O'Connor talks to scientists studying how atrophy in the hippocampus is associated with afflictions such as impaired memory, dementia, Alzheimer’s Disease, depression and PTSD. Wayfinding is a captivating book that charts how our species' profound capacity for exploration, memory and storytelling results in topophilia, the love of place. "O'Connor talked to just the right people in just the right places, and her narrative is a marvel of storytelling on its own merits, erudite but lightly worn. There are many reasons why people should make efforts to improve their geographical literacy, and O'Connor hits on many in this excellent book—devouring it makes for a good start." —Kirkus Reviews

Download or read book How to Navigate Life written by Belle Liang, PhD and published by St. Martin's Press. This book was released on 2022-08-02 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: An essential guide to tackling what students, families, and educators can do now to cut through stress and performance pressure, and find a path to purpose. Today’s college-bound kids are stressed, anxious, and navigating demands in their lives unimaginable to a previous generation. They’re performance machines, hitting the benchmarks they’re “supposed” to in order to reach the next tier of a relentless ladder. Then, their mental and physical exhaustion carries over right into first jobs. What have traditionally been considered the best years of life have become the beaten-down years of life. Belle Liang and Timothy Klein devote their careers both to counseling individual students and to cutting through the daily pressures to show a better way, a framework, and set of questions to find kids’ “true north”: what really turns them on in life, and how to harness the core qualities that reveal, allowing them to choose a course of study, a college, and a career. Even the gentlest parents and teachers tend to play into pervasive societal pressure for students to PERFORM. And when we take the foot off the gas, we beg the kids to just figure out what their PASSION is. Neither is a recipe for mental or physical health, or, ironically, for performance or passion. How to Navigate Life shows that successful human beings instead tap into their PURPOSE—the why behind the what and how. Best of all, purpose is a completely translatable quality to every aspect of life, from first jobs to last jobs and everything in between.

Download or read book Directed Sonar Sensing for Mobile Robot Navigation written by John J. Leonard and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph is a revised version of the D.Phil. thesis of the first author, submitted in October 1990 to the University of Oxford. This work investigates the problem of mobile robot navigation using sonar. We view model-based navigation as a process of tracking naturally occurring environment features, which we refer to as "targets". Targets that have been predicted from the environment map are tracked to provide that are observed, but not predicted, vehicle position estimates. Targets represent unknown environment features or obstacles, and cause new tracks to be initiated, classified, and ultimately integrated into the map. Chapter 1 presents a brief definition of the problem and a discussion of the basic research issues involved. No attempt is made to survey ex haustively the mobile robot navigation literature-the reader is strongly encouraged to consult other sources. The recent collection edited by Cox and Wilfong [34] is an excellent starting point, as it contains many of the standard works of the field. Also, we assume familiarity with the Kalman filter. There are many well-known texts on the subject; our notation derives from Bar-Shalom and Fortmann [7]. Chapter 2 provides a detailed sonar sensor model. A good sensor model of our approach to navigation, and is used both for is a crucial component predicting expected observations and classifying unexpected observations.

Download or read book After the Map written by William Rankin and published by University of Chicago Press. This book was released on 2016-07-01 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: For most of the twentieth century, maps were indispensable. They were how governments understood, managed, and defended their territory, and during the two world wars they were produced by the hundreds of millions. Cartographers and journalists predicted the dawning of a “map-minded age,” where increasingly state-of-the-art maps would become everyday tools. By the century’s end, however, there had been decisive shift in mapping practices, as the dominant methods of land surveying and print publication were increasingly displaced by electronic navigation systems. In After the Map, William Rankin argues that although this shift did not render traditional maps obsolete, it did radically change our experience of geographic knowledge, from the God’s-eye view of the map to the embedded subjectivity of GPS. Likewise, older concerns with geographic truth and objectivity have been upstaged by a new emphasis on simplicity, reliability, and convenience. After the Map shows how this change in geographic perspective is ultimately a transformation of the nature of territory, both social and political.

Download or read book Navigation by Judgment written by Dan Honig and published by Oxford University Press. This book was released on 2018-03-29 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foreign aid organizations collectively spend hundreds of billions of dollars annually, with mixed results. Part of the problem in these endeavors lies in their execution. In Navigation by Judgment, Dan Honig argues that high-quality implementation of foreign aid programs often requires contextual information that cannot be seen by those in distant headquarters. Drawing on a novel database of over 14,000 discrete development projects across nine aid agencies and eight paired case studies of development projects, Honig shows that aid agencies will often benefit from giving field agents the authority to use their own judgments to guide aid delivery. This "navigation by judgment" is particularly valuable when environments are unpredictable and when accomplishing an aid program's goals is hard to accurately measure. Highlighting a crucial obstacle for effective global aid, Navigation by Judgment shows that the management of aid projects matters for aid effectiveness.

Download or read book The Science of Time 2016 written by Elisa Felicitas Arias and published by Springer. This book was released on 2017-10-05 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: The uses of time in astronomy - from pointing telescopes, coordinating and processing observations, predicting ephemerides, cultures, religious practices, history, businesses, determining Earth orientation, analyzing time-series data and in many other ways - represent a broad sample of how time is used throughout human society and in space. Time and its reciprocal, frequency, is the most accurately measurable quantity and often an important path to the frontiers of science. But the future of timekeeping is changing with the development of optical frequency standards and the resulting challenges of distributing time at ever higher precision, with the possibility of timescales based on pulsars, and with the inclusion of higher-order relativistic effects. The definition of the second will likely be changed before the end of this decade, and its realization will increase in accuracy; the definition of the day is no longer obvious. The variability of the Earth's rotation presents challenges of understanding and prediction. In this symposium speakers took a closer look at time in astronomy, other sciences, cultures, and business as a defining element of modern civilization. The symposium aimed to set the stage for future timekeeping standards, infrastructure, and engineering best practices for astronomers and the broader society. At the same time the program was cognizant of the rich history from Harrison's chronometer to today's atomic clocks and pulsar observations. The theoreticians and engineers of time were brought together with the educators and historians of science, enriching the understanding of time among both experts and the public.
