Viruses have shaped human civilisation and life on Earth in ways we are only beginning to understand. Pranay Lal's  Invisible Empire  shows us tantalising glimpses of powerful hidden forces that affect each and every one of us. Fascinating and illuminating. -- SIDDHARTHA MUKHERJEE, Pulitzer Prize-winning author of The Emperor of All Maladies Most of us think of viruses as agents of disease but they are among the most diverse and abundant organisms in the natural world, right at the boundary between the living and non-living. In this engaging and beautifully illustrated account, Pranay Lal takes us on a grand tour of the world of viruses, revealing their history and the amazing and varied roles they play in nature. Anyone interested in the natural world including young readers will greatly enjoy this book. -- VENKI RAMAKRISHNAN, winner of the 2009 Nobel Prize in Chemistry Viruses are one of life's most powerful and mysterious forces, and shape our world in ways that we don't fully understand.  Invisible Empire  illuminates a world which has so far only been looked at through the narrow lens of disease. This is one of those rare books that can truly change the way you see the world around you. -- LARRY BRILLIANT, epidemiologist and author

An examination of the role of theory in applied econometrics. Econometrics is a study of good and bad ways to measure economic relations. In this book, Bernt Stigum considers the role that economic theory ought to play in such measurements and proposes a formal science of economics that provides the means to solve the measurement problems faced by econometric researchers. After describing the salient parts of a formal science of economics, Stigum compares its methods with the methods of contemporary applied econometrics. His goal is to develop a basis for meaningful discussion of the best way to incorporate economic theory in empirical analysis. Stigum conceives two scenarios for research in applied econometrics: contemporary econometrics in the tradition of Trygve Haavelmo and the formal theory-data confrontation envisioned by Ragnar Frisch. Stigum presents case studies of economic phenomena, contrasting the empirical analysis prescribed by contemporary applied econometrics with the empirical analysis prescribed by a formal theory-data confrontation. He finds significant and provocative differences. Which are we to believe when the statistical analyses of these two methodologies yield very different descriptions of the behavior characteristics of data variables and inferences about social reality? Stigum points to three aspects of contemporary econometric methodology that may benefit from serious discussions: the analysis of positively valued time series, a suspect characteristic of qualitative response models, and the search for linearly cointegrated time series. These three aspects are of as much concern to formal econometrics as they are to contemporary econometrics.
