Measurements and experiments are made each and every day, in fields as disparate as particle physics, chemistry, economics and medicine, but have you ever wondered why it is that a particular experiment has been designed to be the way it is. Indeed, how do you design an experiment to measure something whose value is unknown, and what should your considerations be on deciding whether an experiment has yielded the sought after, or indeed any useful result? These are old questions, and they are the reason behind this volume. We will explore the origins of the methods of data analysis that are today routinely applied to all measurements, but which were unknown before the mid-19th Century. Anyone who is interested in the relationship between the precision and accuracy of measurements will find this volume useful. Whether you are a physicist, a chemist, a social scientist, or a student studying one of these subjects, you will discover that the basis of measurement is the struggle to identify the needle of useful data hidden in the haystack of obscuring background noise.

History and archaeology tell us that when our far ancestors began to settle in localized groups, they codified their lives and experiences, and formed a collective for mutual support. This proto-civilization would have arisen from each individual¿s questions about the world, and their attempt to understand themselves and their place in the world. These groups, or tribes, evolved rules of conduct to facilitate communal living, and made a calendar for the group¿s celebration of harvests, and other events upon which the group was utterly dependent.This process of social evolution is the origin of religion, and of a magical way of looking at Nature. Eventually, this developing worldview was also the origin of science, which is our investigation of Nature to understand something of what is happening around us, and to use this knowledge to ensure our survival in a violent, indifferent Universe. After all, science and religion seek to answer the same question: Why and how isthe natural world the way it is? This book seeks to show how science evolved from religion and magic, in response to a need to understand Nature.

Examines the origin of the molecular architecture of crystals; a topic that is becoming increasingly important and is often termed, crystal engineering. Such studies are a means of predicting crystal structures, and of designing crystals with particular properties by manipulating the structure and interaction of large molecules.
