From one of the world’s leading data scientists, a landmark tour of the new science of idea flow, offering revolutionary insights into the mysteries of collective intelligence and social influence If the Big Data revolution has a presiding genius, it is MIT’s Alex “Sandy” Pentland. Over years of groundbreaking experiments, he has distilled remarkable discoveries significant enough to become the bedrock of a whole new scientific field: social physics. Humans have more in common with bees than we like to admit: We’re social creatures first and foremost. Our most important habits of action—and most basic notions of common sense—are wired into us through our coordination in social groups. Social physics is about idea flow, the way human social networks spread ideas and transform those ideas into behaviors. Thanks to the millions of digital bread crumbs people leave behind via smartphones, GPS devices, and the Internet, the amount of new information we have about human activity is truly profound. Until now, sociologists have depended on limited data sets and surveys that tell us how people say they think and behave, rather than what they actually do. As a result, we’ve been stuck with the same stale social structures—classes, markets—and a focus on individual actors, data snapshots, and steady states. Pentland shows that, in fact, humans respond much more powerfully to social incentives that involve rewarding others and strengthening the ties that bind than incentives that involve only their own economic self-interest. Pentland and his teams have found that they can study patterns of information exchange in a social network without any knowledge of the actual content of the information and predict with stunning accuracy how productive and effective that network is, whether it’s a business or an entire city. We can maximize a group’s collective intelligence to improve performance and use social incentives to create new organizations and guide them through disruptive change in a way that maximizes the good. At every level of interaction, from small groups to large cities, social networks can be tuned to increase exploration and engagement, thus vastly improving idea flow. Social Physics will change the way we think about how we learn and how our social groups work—and can be made to work better, at every level of society. Pentland leads readers to the edge of the most important revolution in the study of social behavior in a generation, an entirely new way to look at life itself. From the Trade Paperback edition.

This manual is one of a series of four practical and technical books and manuals prepared by the International Society of Radiographers and Radiological Technologists (ISRRT) on behalf of the Global Steering Group for Education and Training in Diagnostic Imaging, established by the World Health Organisation in 1999. The aim of these books is to assist medical and technical personnel working in the area of diagnostic imaging in small and mid-size hospitals.The present volume on basic physics of ultrasonographic imaging procedures provides clear and concise information on the physics behind ultrasound examinations in diagnostic imaging. It attempts to present the subject from a simple approach that should make it possible for the target groups to comprehend the important concepts which form the physical basis of ultrasonic imaging. The main target group of this manual is radiological technologists and radiographers working with diagnostic ultrasound in developing countries. Clinicians and nurse practitioners may also find the simple presentation appealing. A conscious effort has been made to avoid detailed mathematical treatment of the subject. The emphasis is on simplicity.

For many centuries, Aristotle's Physics was the essential starting point for anyone who wished to study the natural sciences This book begins with an analysis of change, which introduces us to Aristotle's central concepts of matter and form, before moving on to an account of explanation in the sciences and a defence of teleological explanation. Aristotle then turns to detailed, important, and often ingenious discussions of notions such as infinity, place, void, time, and conintuity. He ends with an argument designed to show that the changes we experience in the world demand as their cause a single unchanging cause of all change, namely God. This is the first complete translation of Physics into English since 1930. It presents Aristotle's thought accurately, while at the same time simplifying and expanding the often crabbed and elliptical style of the original, so that it is very much easier to read. A lucid introduction and extensive notes explain the general structureof each section of the book and shed light on particular problems.

The first edition of this highly successful book appeared in 1975 and evolved from lecture notes for classes in physical optics, diffraction physics and electron microscopy given to advanced undergraduate and graduate students. The book deals with electron diffraction and diffraction from disordered or imperfect crystals and employed an approach using the Fourier transform from the beginning instead of as an extension of a Fourier series treatment. This third revised edition is a considerably rewritten and updated version which now includes all important developments which have taken place in recent years.
