In Ten Trips neuropsychologist Andy Mitchell takes ten different psychedelic drugs in ten different settings, puncturing the hype while providing the fullest picture yet of their limitlessly fascinating possibilities. Once demonised and still largely illegal, psychedelic drugs are now officially a 'breakthrough therapy', used to treat depression, trauma and addiction and to enhance well-being. But as neuropsychologist Andy Mitchell shows in this deeply serious yet wildly entertaining investigation, this approach misses what is so strange and valuable about them: the psychedelic experience itself. In Ten Trips he takes ten different compounds, some famous, others obscure, journeying from a neuroimaging lab in London to the Colombian Amazon via Silicon Valley and his friend's basement kitchen. His encounters with scientists and gangsters, venture capitalists and con-men, psychonauts and shamans provide a panoramic view of psychedelics today: their capacity for healing but also trauma, for transcendence and corruption, profundity and hilarity. By removing psychedelics from their indigenous and underground cultures, we risk losing the very things we need to harness them. To make them safe or normal might ultimately destroy what makes them potent. That potential is indeed great, not as an antidote to mental illness - none exists - but as a way of changing our whole perspective on mental health and flourishing. Ten Trips is a dazzling, perception-shifting odyssey that shows how psychedelics can re-enchant us with the world.

A neuropsychologist takes ten different psychedelic drugs in this panoramic, profound and wildly entertaining investigation. 'Original and thrilling' Mike Jay, author of Psychonauts 'Utterly compelling' Mark Miodownik, author of Stuff Matters 'A hair-raising hurtle of a ride' Henry Shukman, author of One Blade of Grass 'The psychedelic world has been waiting for this book' Professor Erika Dyck Psychedelics may have made a comeback but they still remain a mystery. They are now a 'breakthrough therapy' for mental illness but the truth is we have only a vague idea how they work and there is a limit to what science alone can reveal. To have any hope of understanding them fully, we need first to broaden our view - dramatically - of what they are. In this daring, perception-shifting odyssey, clinical neuropsychologist Andy Mitchell takes ten different drugs in ten different settings, journeying from a neuroimaging lab in London to the Colombian Amazon via Silicon Valley and his friend's basement kitchen. His encounters with scientists and gangsters, venture capitalists and con men, psychonauts and shamans, as well as with the drugs themselves, reveal the reality of psychedelics in all their richness, darkness, hilarity, wonder and strangeness. We see that the drive to extract these substances from their indigenous and underground cultures comes with risk as well as opportunity, and that to make them safe or normal might ultimately destroy what makes them potent. We also see, more vividly than ever before, what makes them so rapturously enchanting and confounding. 'Beguiling, captivating, mind-expanding. It's impossible to read this book and not be tempted to replicate some of its wild, sanity-stretching forays into the peculiarities of human perception' Stuart Ritchie, author of Science Fictions 'A dazzling, timely book, as deep and poignant as it is madcap and hilarious' Mark Lythgoe, Director of the Centre for Advanced Biomedical Imaging, University College London

Learn how to get better answers in map analysis when you use spatial measurements and statistics. Spatial measurements and statistics give you a powerful way to analyze geospatial data, but you don't need to understand complex mathematical theories to apply statistical tools and get meaningful results in your projects. The Esri Guide to GIS Analysis, Volume 2: Spatial Measurements and Statistics, second edition, builds on Volume 1 by taking you to the next step of GIS analysis. Learn to answer such questions as, how are features distributed? What is the pattern created by a set of features? Where can clusters be found? This book introduces readers to basic statistical concepts and some of the most common spatial statistics tasks: measuring distributions, identifying patterns and clusters, and analyzing relationships. Updated with the latest and most useful software tools and revised explanations, each chapter in The Esri Guide to GIS Analysis, Volume 2 is organized to answer basic questions about the topic. Explore how spatial statistical tools can be applied in a range of disciplines, from public health to habitat conservation. Learn how to quantify patterns beyond visualizing them in maps. Examine spatial clusters through an updated chapter on identifying clusters. Use The Esri Guide to GIS Analysis, Volume 2, second edition, to understand the statistical methods and tools that can move your work past mapping and visualization to more quantitative statistical assessment.

Do more with your GIS and understand the foundation of spatial analysis: geographic patterns and relationships. A geographic information system (GIS) enables so much more than mapping. A GIS inherently enables spatial analysis that can give you a better understanding of your geographic data. GIS analysis reveals answers to questions like: Where is it? Where's the most and least? How much is where? What's inside? What's nearby? What's changed But how do you get started? The second edition of The Esri Guide to GIS Analysis, Volume 1 shows how and more. With easier to read maps and text, The Esri Guide to GIS Analysis, Volume 1, second edition, dives beneath the surface of mapping, beyond displaying data to using it to reveal geographic insights. Learn the basic concepts of spatial analysis and GIS. Build on that understanding with essential map-building skills to unveil and display patterns and relationships. The Esri Guide to GIS Analysis, Volume 1, second edition, also includes a guide to online lessons that reinforce the concepts and demonstrate GIS application. Written for both new and experienced GIS users using an easy to follow format, the second edition of The Esri Guide to GIS Analysis, Volume 1 helps you build a foundation of the basic tasks needed to handle a wide range of analysis applications and prepares you for more advanced GIS skills.

The third volume in the Esri Guide to GIS Analysis series, Modeling Suitability, Movement, and Interaction describes practical applications of modeling concepts in a geographic information system (GIS). Modeling allows users to explore different scenarios and the impacts of various options, before making a decision.This book covers a broad range of methods for spatial interaction, site selection, routing, and scheduling, and explains the theory behind them so users can better interpret the analysis results. It also describes how a particular method is implemented within a GIS. With full-color maps and illustrations and sample applications, this book will help students studying GIS and professional GIS analysts better use models to evaluate locations and analyze movement
