When a magician performs his impressive tricks, his audience would like to know how he does it, but they concede that he keeps his secrets to himself. Much of what today’s technical systems can achieve may seem like magic to an outsider. Yet, there are no tricks behind it, but rather a wealth of insights gained over the centuries by great thinkers and researchers, which have been shared with humanity. Unlike magicians, scientists and engineers do not want to keep their knowledge to themselves. They are accustomed to sharing their expertise with colleagues and students in their field, but often find it challenging to select and present the relevant content in an understandable way for laypersons outside their discipline. This book aims to address that gap, presenting information in a clear and easily understandable manner.
