Sixty years after the Dallas shootings - and despite more and more documents becoming available - a multitude of myths continue to surround the most famous assassination attempt of the 20th century. With his work, the author tries to bring a little more light into the thicket of conspiracy theories and facts, especially for the layperson. The aim should be to be able to form an opinion based on undisputed facts, even without any specialist knowledge and purely on the basis of common sense.

This book offers up-to-date information and guidance on the application of metrology in legal proceedings, clarifying the limits of validity of scientific evidence and presenting an illuminating series of case studies in which measurement uncertainty has played an important role. The fundamental concepts of metrology are discussed, and it is explained how metrology is capable of quantifying the reliability of measurement results and thereby contributing to appropriate decision making. With the aid of the presented case studies, this book will assist readers in understanding how legal decisions should be made in the presence of uncertainty. Areas covered in those studies include breath alcohol concentration analysis, and DNA profiling. Nowadays, decisions in most legal cases are based on evidence obtained through scientific analysis involving the acquisition of accurate measurements. Against this background, Forensic Metrology will be of value for lawyers and judges in both civil and common law countries, as well as engineers and other scientists with an interest in the subject.

Wenn du spürst, wie der letzte Atemzug ihren Körper verlässt, schaust du ihnen in die Augen. Eine Person in dieser Situation ist Gott! Diese Äußerung stammt von dem berüchtigten Serienkiller Theodore Bundey. In mir persönlich ruft dieses Zitat nichts hervor.Aber wohl bei Ihnen; denn warum sollten Sie sich sonst ein Buch über Serienmörder kaufen wollen?Pures Interesse, Neugier oder doch eher der verkappte Versuch nur einmal über allem stehen zu wollen, sein, falls überhaupt vorhandenes, rudimentäres Ich vermeintlich strahlend präsentieren zu dürfen, wenn auch nur in der Fantasie? Einmal der vermeintliche Sieger sein, um seine alltäglich gefühlte und auch tatsächliche Unwichtigkeit und Nichtigkeit besser ertragen zu können. Nein, Ich doch nicht, so wird Ihre lapidare Antwort lauten. Natürlich nicht. Natürlich sind Sie über jeden Zweifel erhaben. Aber sicher doch und eben so sicher sind Sie einer von diesen Glückskeksen die denken etwas grandioses darzustellen um dann kurz vor dem Einschlafen doch daran erinnert zu werden, was für ein Versager man eigentlich ist. Nein? Aber ganz bestimmt.Warum? Das werden Sie wissen und auch verstehen wenn Sie dieses Buch gelesen haben.

Forgeries present a daunting problem to art historians, museums, galleries and curators who face challenges in determining the authenticity of paintings. Recent progress in science has led to the development of new methods for investigating works of art, and can provide new insights into the materials found in paintings. The rise in the value of paintings together with the knowledge and skills of forgers highlights the need to develop reliable scientific procedures to identify fakes. Given the complexity of materials in paintings and the convergence of various disciplines, a methodological approach for nvestigations of paintings is based on art historical, curatorial, aesthetic, technical and scientific evaluation. In this book sophisticated digital and analytical techniques are reviewed for the identification of materials (pigments, binders, varnishes, adhesives) and the physical characteristics of paintings such as brushstrokes, craquelure and canvas weaves. This book presents an updated overview of both non-invasive and micro-invasive techniques that enable the material characterization of paintings. The materials constituting a painting are reviewed, as are ways that changes in materials over time can provide insights into chronology and physical history. State-of the art digital metods including multi and hyper-spectral imaging and computational approaches to data treatment will be presented. Analytical techniques developed and optimized to characterize binders, varnishes, and pigments are reviewed, focusing on materials which can provide information on ageing or provenance. Case studies of applications of synchrotron-based methods and the analysis of paintings are given, as are chapters devoted to legal aspects related to authenticity.
