Brilliant scientific successes have helped shape our world, and are always celebrated. However, for every victory, there are no doubt numerous little-known blunders. Neuroscientist Simon LeVay brings together a collection of fascinating, yet shocking, stories of failure from recent scientific history in When Science Goes Wrong. From the fields of forensics and microbiology to nuclear physics and meteorology, in When Science Goes Wrong LeVay shares twelve true essays illustrating a variety of ways in which the scientific process can go awry. Failures, disasters and other negative outcomes of science can result not only from bad luck, but from causes including failure to follow appropriate procedures and heed warnings, ethical breaches, quick pressure to obtain results, and even fraud. Often, as LeVay notes, the greatest opportunity for notable mishaps occurs when science serves human ends. LeVay shares these examples: To counteract the onslaught of Parkinson's disease, a patient undergoes cutting-edge brain surgery using fetal transplants, and is later found to have hair and cartilage growing inside his brain. In 1999, NASA's Mars Climate Orbiter spacecraft is lost due to an error in calculation, only months after the agency adopts a policy of "Faster, Better, Cheaper." Britain's Bracknell weather forecasting team predicts two possible outcomes for a potentially violent system, but is pressured into releasing a ‘milder' forecast. The BBC's top weatherman reports there is "no hurricane", while later the storm hits, devastating southeast England. Ignoring signals of an imminent eruption, scientists decide to lead a party to hike into the crater of a dormant volcano in Columbia, causing injury and death. When Science Goes Wrong provides a compelling glimpse into human ambition in scientific pursuit.

What is this book about?ASP.NET 1.0 is the final release of Microsoft's Active Server Pages (ASP). It is a powerful server-based technology designed to create dynamic, interactive, HTML pages for web sites and corporate intranets. ASP.NET is a core element of Microsoft's exciting .NET vision, building on the strengths of the .NET Framework to provide many new features not seen in previous versions of ASP.This book, entirely revised and updated for the final release, will provide you with a step-by-step introduction to ASP.NET using VB.NET, with plenty of worked examples to help you to gain a deep understanding of what ASP.NET is all about, and how you can harness it to build powerful web applications.What does this book cover?In this book, you will learn how toCreate basic ASP.NET pages with VB .NETUnderstand the concepts of Object Oriented ProgrammingWork with data and XMLDebug and handling errors in your codeUse ASP.NET Server ControlsCreate user controls and componentsExplore the world of Web servicesOptimize performanceSecure your applicationWho is this book for?This book is aimed at relatively inexperienced web builders who are looking to enrich their sites with dynamically-generated content, and want to learn how to start building web applications using ASP.NET. Developers who have a little experience with previous versions of ASP (and are looking to move over to ASP.NET), may also find this book helpful in getting a simple grasp on what ASP.NET is, what it does, and how it can be used. Experience of basic HTML is required, but previous experience of ASP or VBScript is not essential. We'll be teaching the basics of VB .NET in this book, so prior experience of the language is not required.
